60 Claims.

This invention relates to lasting machines, and is herein illustrated as applied to a machine organization of the same general character as disclosed in United States Letters Patent No. 1,843,-

5 232, granted on February 2, 1932 upon an application of mine, but modified in certain respects as further disclosed in Letters Patent No. 1,979,269, granted also upon an application of mine on November 6, 1934, and in Letters Patent No. 2,026,539, granted on January '7, 1936 upon still another application of mine. The present invention has particularly in View further improvements in an organization of that character;

but it is to be understood that in various aspects '15 the invention is not limited to machines of the 69 anism for illustrated type.

In general similarity to prior machines, the machine herein shown is provided with wipers for wiping the margin of the toe end of an upper in- 30 wardly over an insole on a last, and with a device for clamping the upper about the toe and for also wiping it heightwise of the last, the clamping device being so controlled as to permit it to adjust itself to the lateral swing of the forepart of a right or a left last. In accordance with the present invention there is further provided novel means whereby the toe wipers are differently adjusted for right and left lasts under control of the clamping device, thus aifording better insurance that in operating on shoes in which there are pronounced differences between rights and lefts the wipers will be so positioned as to wipe the margin of the upper inwardly the proper distances from the opposite side edges of the insole.

For the purpose in view, the construction herein shown includes eccentric members arranged to control portions of the wiper-closing mechanisms and adjustable by the clamping device to effect a corresponding adjustment of the wipers. To insure against any such action of the wiper-closing mechanisms on the eccentric members as to relax the pressure of the clamping device on the shoe when the wipers are operated, there is further provided means for locking the clamping device against movement in directions away from the sides of the toe after the adjustment of the wipers.

In a further aspect, the invention provides novel means for determining the position of each 59 shoe with respect to lateral tipping movement, to

insure that the bottom of the shoe will extend laterally in proper relation to the plane of end wipers, herein shown as the toe wipers. As herein illustrated, this means comprises a device mov- 55 able into engagement with the opposite side porvice from operative position to. make way for the wipers. More particularly, in the construction shown the shoe-positioning device is supported on a movable carrier provided with a presser foot for engaging the shoe and moving it heightwise as heretofore, and is arranged to engage and position the shoe before the presser foot engages it, after which control of the shoe is transferred from the positioning device to the presser foot in response to further movement of the carrier.

Machines of the illustrated type include heel wipers mounted for tipping movements about an axis extending lengthwise of the shoe, and a de' vice controlled by engagement with the bottom of the heel end' of the shoe for tipping them asdetermined by the shoe into proper relation to the 'shoe bottom To insure greater accuracy in such positioning of the wipers, this device in the construction herein shown is provided with presser feet arranged to engage the opposite side portions of the heel end of the shoe bottom in the pathof the wipers, the presser feet being movable lengthwise of the shoe by the action of the wipers thereonto make way for the wipers.

To assist in properly shaping the upper over the toe end of the last, the invention further provides novel means for clamping the margin of the toe end of the upper to apply a pull to the upper in the power operation of the machine. As illustrated this clamping means comprises a clamp member movableby the operator into position to clamp the margin of the upper outspread in a location over the toe wipers prior to the starting of the power operation of the machine, thus enabling the operator to insure that the upper is properly positioned and clamped before the machine begins its power movements. Novel means also are provided for locking the clamp member in clamping position and for thereafter releasing it, and also novel means for moving it from an initial retracted position into clamping relation to the upper.

In the machine herein shown the toe wipers are maintained in a heated condition to render them more effective in pressing the margin of the upper free from wrinkles and also to accelerate by the heat the drying or hardening of adhesive used to secure the upper to the insole. To increase further the effectiveness of the machine in these respects,v the invention provides means for bringing the machine automatically to a stop at a time in the cycle when the toe wipers are pressing the upper upon. the insole and for starting it again automatically after a predetermined interval, the construction shown being such that the time during which the machine thus remains at rest is adjustably variable.

The above and other features of the invention, including also novel wiper-heating means, novel means for insuring against any objectionable lengthwise tipping movement of the shoe relatively to the toe wipers by mechanism controlling the heel end of the shoe, novel mechanism for locking and unlocking movable heel-end clamping means with which the machine is provided, and various novel details of construction and combinations of parts, will now be more particularly described by reference to the accompanying drawings and pointed out in the claims.

In view of the disclosures in the above-mentioned Letters Patent, only such portions of the complete machine as it is necessary to refer to for an understanding of the novel features of this invention are herein shown, and such parts as are common to the prior disclosures, as well as the manner of their operation, Will be only briefly hereinafter described. The machine herein shown is intended for use only in lasting the opposite end portions of a shoe, the side-lasting mechanisms included heretofore in machines of the illustrated type being omitted, although it is to be understood that the novel features of the invention are applicable to machines which include such side-lasting mechanisms.

For supporting and positioning the last and shoe at the heel end there is provided a block 2 having thereon a heel pin or spindle 4 which enters the spindle hole in the last, the block 2 being supported on the head 6 of a vertical rod 8 which is screw-threaded for upward or downward adjustment in a holder l2. The holder I2 is supported on a vertically movable slide M which is depressible with the shoe against the resistance of a spring IS in response to pressure applied on the bottom of the shoe. The block 2 is freely movable, as heretofore, along guideways l8 in the head 6 (Figs. 11 and 13) which are curved about an axis located at or near the bottom of the heel end of the shoe, so that the shoe may be tipped laterally to position the bottom of its forepart in proper relation to the toe wipers without any substantial bodily lateral displacement of the heel end of the shoe. In the construction herein shown, however, the means provided heretofore for limiting such tipping movement of the shoe by contact with a side face of the heel end of the last and for thereby determining the position of the shoe is omitted, the position of the shoe being determined by other means hereinafter described.

To last the heel end of the shoe there are provided heel wipers 20 (Figs. 1 and 11) for wiping the margin of the upper inwardly over the insole and a heel band 22 for clamping the upper around the heel end of the last. The wipers and the heel band are carried as heretofore by a slide 24 guided for movements lengthwise of the shoe on a pair of horizontal rods 26, only one of which is shown in the drawings, which are mounted on the vertically movable slide I4. The slide 24 is maintained initially in an idle position comparatively remote from the shoe support by latch mechanism constructed somewhat differently than heretofore, as hereinafter described, this mechanism being movable by the operator to release the slide to the action of a spring 28 which then moves the slide toward the shoe support to a fixed position relatively to the vertical slide I4. As fully disclosed in the previously mentioned Letters Patent No. 2,026,539, the holder l2 which supports the heel end of the last and shoe is movable in directions lengthwise of the shoe along guideways on the slide I l and is moved toward the right (Fig. 1) by a spring 30 when the slide 24 has arrived substantially at the end of its movement toward the shoe support.

The spring 30 is released by a latch-32' operated by ascrew 34 carried by-the slide 24; all as fully disclosed in the above-mentioned LettersPatent. The'shoe is thus carried by the holder I2 into contact with the heel band 22 which determines the lengthwise position of the shoe.

The above-mentioned latch mechanism comprises a lever 36- pivotally mounted ona rod 38 supported by'a bracket 40 which is fast on-the rods 26, this lever in the construction herein shown having fast thereon a plate 42 (Fig. 23') provided with a shoulder 44 arranged to engage a shoulder 46 on a bar 48 secured to the lower-end of the slide 24. It will be understood that when the shoulder 44 is thus in engagement .with the shoulder 46 the slide 24 is held in'retracted position against the resistance of the spring. The slide 24 is released as heretofore; prior to the starting of the power operation of the machine, by downward movement of the lever 36 effected by the operator through a rod 50 against the resistance of a spring 52 (Fig. 1"),andthe slide is returned to its idle position near-the endofthe cycle of operations of the machine by'downward movement of a rod 54 (Fig. 1) connected by a chain 56 to the above-mentioned bar 48. This chain engages a sprocket wheel 58 mounted to turn on the above-mentioned rod 38, thesprocket wheel in the construction herein shown being eccentrically mounted on the rod and soarranged that the. portions thereof which arefarthest from its axis are effective on the chain as the retractive movement is imparted to-the slide 24. This reduces the. amount of power required to retract theslide without the inconvenience of providing an unduly large sprocket wheel.

The construction herein shown is such that the slide 24 is positively locked during the operation or the machine on the shoe against any retractive movement such as might result from pressure of the shoe on the heel band 22. For this purpose the left-hand end of the plate 42 is arranged to engage the right-hand face ofthe bar '48, as illustrated in Fig. 23. In order to release the slide 24 to permit it to be retracted by the chain 56 there is provided means for swinging the lever 36 downwardly far enough to withdraw the plate 42 from contact with the right-hand face of the bar 48. This means comprises downwardly extending cam members 60 (Figs.22 and 23) formed on a member 62 which has an arm 64 slidingly movable in a guideway in the bar 48 and to which the chain 56 is directly connected, these cam members being arranged to act onlugs 66 formed on lateral extensions ofthe plate 42. Springs 68 mounted in sockets in the member 62 and engaging the bar 48 hold the member 62 in such a position relatively to the bar that the cam members 60 are at theleft of the lugs 66 when the slide 24 is locked in its operating position by the plate 42, the chain 56 being slack enough to permit this. When the chain is operated to retract the slide 24 to its idle position the first effect of the chain is to move the member 62 to the right against the resistance of the springs 68, thus rendering the cam members 60 effective on the lugs 66 to force the lever 36 far enough downward to release the bar 48. Thereafter the slide 24 is retracted by the continued movement of the chain.

The heel-lasting wipers 20, as disclosed in the abovementioned Letters Patent No. 2,026,539,are mounted for swinging or closing movements on a stud I0 (Fig. 11) carried by the head 12 of a plunger I4 which serves as a wiper carrier and is: mounted for lengthwise movements and also for turning movements ina holder 16 supported as hereinafter described. The wipers are advanced lengthwise of the shoe by forward movement of theplunger l4 effected: by an arm I8 (Fig. 1) of a bell-crank lever 80, this arm being provided with a plate 82 for engaging a roll 84 on the end of the plunger. As the wipers are thus-advanced they are closed through the action of links 86, only one of'which is herein shown, as more fully disclosed in Letters Patent No. 1,979,269. The wipers are supported initially, as heretofore, in a position higher than when operating on a shoe,--and prior to their operation on the shoe they are depressed to a position determined by the height of the bottom of the heel'end ofthesho'e. As they are depressed they may also be tipped lengthwise and laterally to position them so that their wiping faces will extend in substantially parallel relation to the plane of the=heel seat, their lateral tipping movement being-permittedby the turning of the plungerlfl in the holder I6. For supporting the wipers as above described, the holder I6 is mounted on a plunger 88whichis movable vertically in a recess in the slide 24. and is depressible against the resistance of a spring 90, the wipers being further supported by yieldingly depressible plungers 92, onlyi'one of which is herein shown, mounted in the means which supports theheel band 22 and engaging the lower faces of the wipers. The holder I6 is supported on the plunger 88 by trunnions 9.4 which permit thetipping of the holder and the wipers about an axis extending laterally of the shoe sothatthe wipers will extend lengthwiste ofthe; shoe inparallel relation to the heel sea The wipersare depressed and are properly positioned? as: above described by the operation of a carrier 96 fast on a rod 98Lmounted for vertical movements and for turning movements in the frame of the machine. This carrier is swung from an initialv idle position (Fig. 1) into position tobring partsthereon over the heel end of the shoe, and is then moved downwardly to depress andposition the heel wipers and thereafter also to depress the last and shoe together with these wipers relatively to toe-lasting means hereinafter described. For depressing and positioning the wipers the carrier 96 is provided with means which acts directly on the plunger 88 and with other-means which acts directly on the two wipers themselves in locations over the plungers 92. The means which acts on the plunger 08 differs in construction from the means provided heretcfore for this purpose, the construction herein shown being more readily and quickly adjustable to vary the amount of downward movement imparted to the plunger. Secured to the carrier 96 is a bracket I00:in which is mounted a tubular member I02 having a head I04 on its lower end for engaging the top of the plunger 88. Confined in the member I02 is a spring I06 the lower end of which engages a pin I08 fast in the bracket I00 and extending through slots I I0 in the member I02. At its upper end the spring I06 abuts against a screw II2 which is threaded in the member-I02. Pivotally mounted on a stud II4 on the bracket I00 is an arm I I6 arranged to bear on the top of thescrew I I2 and thus to determine the height to which the tubular member I02 is raised by the spring I06. The arm II6 carries a. spring-pressed. pin II8 (Fig. 12) arranged to enter one or another of a plurality of holes I20 in the bracket I00 to-hold the arm 6 in adjusted position. As shown in Fig. 11, the-holes I20 are designated by numerals on the bracket I to assist the operator in determining the proper adjustment of the arm II6, these numer- 5 als having no particular significance with reference to shoe characteristics. The operator sets the arm H6 in a position which may be determined by trial in beginning the use of the ma chine on shoes of a particular style or character, 10 the object being to depress the plunger 38 to such a position, relatively to the means on the carrier 96 which acts directly on the top of the wipers themselves, that the wipers will extend lengthwise of the shoe in directions substantially parallel to the heel seat.

The above-mentioned means on the carrier 96 for controlling the wipers by contact therewith over the plungers 92 comprises, as heretofore, two arms I22, one of which is shown in Fig. 1 and 20 the other in Fig. 11, these arms being part of a holder I24 which is mounted on the carrier 96 for rocking or tipping movements laterally of the shoe. As more fully disclosed in Letters Patent No. 1,979,269, provision for such tipping of the 25 holder I24 is afforded by a pair of curved slots in the holder in which lie rolls supported on the carrier 96, one of these slots and the cooperating roll being shown respectively at I26 and I28 in Fig. 1. It will thus be understood that the direc- 30 tion in which the wipers 20 extend laterally of the shoe is determined by the arms I22 in contact therewith and depends upon the position of the holder I24. The position of the holder is determined, as heretofore, by means controlled by the shoe itself, this means also determining by contact with the shoe the position to which the wipers are depressed relatively to the heel seat. The present invention, however, provides for this purpose a construction different from that used heretofore, an object being to facilitate the control of the holder I24 by the shoe and to insure greater accuracy in the positioning of the wipers. As shown in Fig. 11, there is mounted for vertical movement in the holder I24 a slide I30 in the same location as a corresponding slide shown in Letters Patent No. 1,979,269 but differing therefrom in construction. The slide I30 in the construction herein shown has an inclined downwardly extending arm I32 in the lower end of which there is a slot to receive a lug I34 projecting laterally from the lower end of a bar I36 which extends upwardly adjacent to the holder I24 with its upper end portion in contact with the holder, the lug I34 being secured to the arm I32 by a pin I38. Pivotally mounted on a pin I40 in the upper end portion of the bar I36 is a downwardly extending arm I42 which carries at its lower end two presser feet I44 (Fig. 1) mounted for turning movements about a pin I46 extending laterally of the shoe. The two presser feet I 44 are arranged respectively to engage the opposite side portions of the bottom of the shoe in locations substantially at the forward end of the heel seat, their shoe-engaging portions extending substantial distances lengthwise of the shoe and the ends thereof which are nearest the shank portion of the shoe being curved upwardly. It will be understood that by turning about the pin I46 the presser feet adjust themselves to the contour of the shoe bottom. In operating on work of the character herein shown these presser feet actually engage portions of the upper previously laid inward over the insole and fastened by assembling tacks.

- The arm I42 is controlled by a spring I48 which tends to swing it in one direction about the pin I40 and holds it initially with its lower end in engagement with the lower end of the bar I36, as shown in Fig. 11. When the carrier 96 is moved downwardly as hereinbefore described the two presser feet I44 are carried into engagement with the shoe, and if the position of the shoe is such that one of them engages the shoe before the other the holder I24 is tipped as determined by the shoe until both presser feet are seated firmly upon the shoe bottom, the wipers 20 being correspondingly tipped under control of the arms I22 so that they extend laterally of the shoe in parallel relation to the heel seat. Since the presser feet engage the opposite side portions of the shoe bottom in spaced locations the holder I24 is more readily and accurately controlled by the shoe than in prior constructions having only a single presser foot engaging the intermediate portion of the shoe bottom. It will be understood that the presser feet I44 likewise determine by their contact with the shoe how far the wipers 20 are depressed relatively to the heel seat by the arms I22 and how far the plunger 88 is depressed relatively to the shoe by the member I02 preliminarily adjusted as hereinbefore described. The presser feet are preferably located, as shown, partly in the path of movement of the heel wipers, and near the end of the wiping operation they are engaged and moved lengthwise of the shoe by the wipers, the arm I42 being swung about the pin I40.

The machine herein shown is provided with means constructed substantially as disclosed in Letters Patent No. 1,979,269 for adjusting the presser feet I44 heightwise of the shoe to vary the height of the wipers relatively to the heel seat and for also releasing the presser feet near the end of the operative movement of the wipers to permit the shoe to be forced more firmly upward against the wipers by the action of the spring I6 on the vertical slide I4. As shown in Fig. 11, there is threaded in a block I50 fast on the holder I24 a screw I52 which bears at its lower end on the top of a slide I54 vertically movable in the holder above the slide I30. These two slides are normally connected by a latch I56 pivoted on a pin I58 on the slide I30 and lying, at its upper end in a notch in the slide I54. A spring I60 connected to the block I50 and to the latch I56 tends to move both the slides I30 and I54 upwardly and holds the upper slide I54 against the screw I52 while also holding the latch in operative position. It will accordingly be evident that turning of the screw I52 results in downward or upward adjustment of the slide I30 and the presser feet I44 relatively to the holder I24.

To permit the shoe to be forced more firmly upward against the wipers by the spring I6, the lower end of the latch I 56 is engaged near the end of the operative movements of the wipers by a shoulder I62 on the head 12 of the wiper-operating plunger 14, the latch being thereby withdrawn from the notch in the slide I54 to permit upward movement of the slide I30. This releases the shoe from the control of the presser feet I44. In the return of the parts of the machine to starting positions a spring-pressed pin I 64 in the slide I 54 insures such separation of the two slides I30 and I54 as to cause the latch I56 again to enter the notch in the slide I54.

The toe-lasting mechanism comprises, as heretofore, a slide I66 (Figs. 1 and 7) adjustable in directions lengthwise of the shoe for shoes of different sizes, and a casting I68 supported on the slide I66 for adjustment along curved guidefor wiping the upper upwardly about the toe end 1 of the last as the last is forced downwardly by the previously mentioned presser feet I44 and by other means, hereinafter described, which engages the forepart of the shoe bottom. For thus wiping the upper upwardly there is fast on the casting I68 2. block I12 (Figs. 7 and 1.0) which supports a pair of levers I14 pivotally mounted between their ends on pins I'l6 for swinging movements widthwise of the shoe. On the inner arms of these levers are pins I18 which serve as 20 pivotal supports for blocks I88 (Fig. 9) having slots therein to receive the end portions of a flexible toe band I82. Supported on the. upper face of the block I12 are a plurality of slides I84 extending in a series between the two blocks I88 and having slots in which the band I82 is also mounted. The slides I84 are movable inwardly or outwardly along the supporting face of the block I12 and are controlled by a coil spring I86 located in recesses in their outer sides and con nected at its ends to pins I 88 mounted on ears I89 on the inner ends of the levers I14. It will thus be seen that the slides I84 may be forced outwardly'against the resistance of the spring I86 by pressure of the shoe on the band I82 as the shoe is forced downwardly.

The band-supporting end blocks I88 also are yieldingly controlled to permit them to be forced apart by wedging action of the shoe on the band. For this purpose the outer arm of each lever I14 40 has rotatably mounted therein a stud I98 (Figs. 7 and 10) provided below the arm with a block I92 through which extends a transverse rod'l94, one end of the rod having screw threads thereon in engagement with corresponding threads in one of the blocks I92 and the intermediate portion of the rod being swiveled in the other block. A spring I96 mounted on the rod I94 between the last-mentioned block and a collar I 98 fast on the rod tends to swing the inner band-supporting arms of the levers I14 toward each other and is yieldable to permit these arms to be forced apart. Inward movements of these arms are limited by a collar 288 fast on the rod I94 and engaging that block I92 in which the rod is swiveled. It 53 will be evident that by turning the rod I94 through a hand wheel 282 thereon the band-supporting arms of the levers I14 may be adjusted toward or from each other for shoes of different widths. It will also be evident-that the connec- 60 tions between the two levers I14 permit the forward end portions of the band I82, i. e., the portions which are farthest from the extreme end of the toe, to be swung simultaneously in the same direction laterally of the shoe to permit 65 the band to adjust itself to a right or a left shoe.

As the shoe is depressed to cause the band I82 to wipe the upper upwardly, the toe end of the shoe is engaged, as heretofore, by a rubber toe 70 rest 284 which is forced downwardly by contact of the shoe therewith, the toe rest being-supported on a hollow plunger 286 slidingly movable in a holder 288. In the construction herein shown, for a purpose hereinafter described, the

F5 downward movement of the toe rest and the plunger 286 is resisted initially by a comparatively light spring 2I8 mounted between the closed upper end of the plunger and a flange 2I2 formed on a spool 2I4 fast on a rod 2I6 extending downwardly through an opening in the lower end of the holder 288. Between the flange .2I2 and the lower end of the holder is a heavier spring 2I8 which is compressed by further downward movement of the toe rest after the upper end of the plunger 286 has moved downwardly far enough to engage the upper end of the spool 2 I4. In the construction shown in the previously mentioned Letters Patent No. 2,026,539 the holder 288 was pivotally mounted on the casting I68, by -means of trunnions indicated herein at 228, to permit it to swing with the toe rest lengthwise of the shoe, and such swinging movement was eifected in the downward movement of the toe rest by a cam acting on a roll 222 supported on the plunger 286 so as to cause the toe rest to apply a frictional pull to the upper toward the end of the toe. Return movement of the holder and the toe rest was effected by a spring-controlled plunger 224 mounted in a lug 226 on the holder 288 and engaging a bracket oorrespondingin location to a bracket 228 herein'shown which is fast on the casting I68. For the purpose of operating on shoes which have already been'pulled over and it may be also side lasted, the machine herein shown is provided with means for preventing such swinging movement of the toe rest, the above-mentioned cam being omitted. To this end, there is secured to the bracket 228 a plate 238 having thereon a block 232 interposed between the upper face of the lug 226 and the head of the plunger 224 which engages the bracket 228 above it, so as to lock the holder '288 from swinging about the axes of the trunnions 228. If desired, however, the bracket 228 and the parts thereon may be removed and another bracket provided with a cam, as shown in the last-mentioned Letters Patent, may be substituted therefor, so that by the action of the cam on the roll 222 the toe rest will beswung as formerly as it is depressed. Upward'movement of the toe rest isadjustably limited by a stop screw 234 threaded in the bracket 228 and engaging the roll 222.

For wiping the marginal portion'of the toe end of the upper inwardly over the insole the machine herein shown is provided with a single pair of wipers 236 (Figs. 5, 6 and '7) mounted on a wiper carrier 238 which is movable in directions lengthwise of the shoe along guideways in the casting I68. These wipers are extended lengthwise of the shoe far-enough to engage portions of the upper extending more or less rearwardly of the toe portion of the shoe toward the ballline. The wiper carrier 238-overlies portions of the wipers and has a curved tongue-and-groove connection therewith indicated by dotted lines at 248 in Fig. 6 to guide them for swinging or closing movements about an axis located approximately at their wiping edges, one of the wipers having a small curved extension 242 lying in a correspondingly curved recess in the other wiper to prevent undue separation between the two wipers at the extreme end of the toe when they are in their closed positions. The wipers are supported underneath, in part, by a plate 244 fast on a bracket 246 (Fig. '7) which is secured to the wiper carrier 238, and they are furthersupported in locations opposite the sides of the toe by plates 248 fast on the casting I68. The wiper carrier 238 is operated to advance the wipers lengthwise of the shoe by a gear sector 258 fast on a rock shaft 252 operated by the same means as heretofore in machines of the illustrated type. For closing the wipers laterally of the shoe there are provided, as heretofore, rack bars 254 operated by the rock shaft 252 and adjustably connected by screws 256 to slides 258 mounted in guideways in the casting I68. These slides are connected to the wipers by mechanisms constructed differently than heretofore. Each of these mechanisms comprises a link 266 pivotally connected at one end by a pin 26! to the corresponding slide 258 and at the other end by a pin 262 to a member 263 mounted to turn about an eccentric 264 which is rotatably mounted, for a purpose hereinafter described, on a stud 266 on the casting I68. The member 263 is connected by a link 268 to a pivot pin 216 which extends upwardly from the wiper 236. It will thus be seen that as the wipers are advanced lengthwise of the shoe by the wiper carrier 238 they are closed laterally of the shoe by the slides 258 which act thereon through the links 260, the members 263 and the links 268, the members 263 turning about the eccentrics 264.

Reference has been made to the fact that the toe band I82 is so controlled that its forward end portions may swing simultaneously in the same direction laterally of a shoe in response to pressure of the shoe thereon. In this way the band adjusts itself to the lateral swing of the forepart of a right or a left shoe, the heel end of which is centralized laterally by the heel band 22. In operating on shoes in which there are pronounced differences between rights and lefts with respect to the lateral swing of the forepart it is desirable that the toe wipers 236 also be differently positioned for rights and lefts, so that they will wipe the margin of the upper inwardly substantially equal distances from the opposite side edges of the insole. Accordingly the machine herein shown is so constructed that the wipers are adjusted to different shoes by the toe band. For this purpose each of the bandcontrolling levers I14 is connected by a link 212 to a plate 214 (Figs. 6 and 8) which is integral with the previously mentioned eccentric 264, the link having fast on one end thereof a block 216 provided with an opening 211 in which lies the ball-shaped upper end 218 of the previously mentioned pin I88. Accordingly, if the forward end portions of the band I82 are swung, for emample, to the right (Fig. 6) by the action of the shoe thereon as the shoe is forced downwardly within the band, the two links 212 are moved by the band to turn the eccentrics 264 in counter clockwise directions, and by such movements of the eccentrics the members 263 which are mounted thereon are swung about the pins 262 and act through the links 268 to swing the wipers 236 in the same direction as the forward ends of the toe band. By the same means both wipers are swung toward the left (Fig. 6) if the forward ends of the toe band are swung in that direction by pressure of a shoe thereon. It will thus be seen that the wipers are adjusted under control of the shoe so that their wiping edges will be substantially equidistant from the opposite side edges of the shoe bottom prior to the opera tion of the wipers on the shoe, and accordingly when they operate they will move inwardly over the shoe bottom substantially equal distances from the opposite side edges of the insole,

After the toe band and the wipers have adjusted themselves to the shoe as above described, the toe band is locked against any such displacement of either of the opposite side portions there of as might result from the action of either of the members 263 on the corresponding eccentric 264 by reason, for example, of resistance of the shoe to the inward movement of either of the wipers. For this purpose there is associated with each of the plates 214 a pawl 280 pivotally mounted on a stud 282 on the casting I 68 and arranged to engage ratchet teeth 284 formed on the plate 214. The pawl is held initially out of engagement with the ratchet teeth by the action of the link 260 on the head of a screw 286 adjustably threaded in a tail of the pawl, and is swung into engagement with the ratchet teeth by a leaf spring 288 when permitted by the link substantially at the beginning of the operative movements 01' the wipers.

In the construction herein shown the toe wipers 236 are maintained in a heated condition in order to render them more effective to wipe the margin of the upper free from wrinkles as well as to accelerate the hardening or setting of adhesive whereby the margin of the upper is secured to the insole. For this purpose there are fastened to a cover plate 290 on the casting I68 heating members 292 having electrical heating units 294 mounted therein, each of the members 292 having a flat lower face 296 (Fig. '1) arranged for sliding contact with an extended fiat face 298 (Fig. 6) formed on an enlarged portion of the previously mentioned link 268 which is adjacent thereto. The link 268 has also an extended fiat lower face arranged for sliding contact with the top of the wiper 236, and it will accordingly be evident that heat is conducted at all times to the wipers from the members 292 through the links 268. For the protection of the operator there is mounted over each heating member 292 a cap 300 preferably covered with felt (Fig. l) or other suitable heat-insulating material.

For better insurance that the toe end of the upper will be conformed tightly to the contour of the last as the shoe is depressed within the band I82, the machine herein shown is provided with means constructed differently than heretofore for clamping the marginal portion of the toe end of the upper and subjecting it to an upward pull in response to the depression of the last. This means comprises a lower clamp member 302 (Figs. 5, 7 and 11) curved to extend around the end of the toe and provided with an upper-clamping portion located immediately over the wipers 236, the member 302 having a forked arm 304 secured by a clamping screw 306 to a bracket 308 which is mounted to turn about a shaft 310 supported in bearings on the top of the cover plate 290. Threaded in the bracket 308 are two screws 3l2 the lower ends of which are arranged to rest on the cover plate to determine the height of the clamp member 302, these screws preferably being so adjusted that the clamp member is supported out of contact with the wipers so as not to interfere frictionally with the adjustment of the wipers to the shoe by the action of the toe band as hereinbefore described. It will be evident that upon loosening the clamping screw 306 the clamp member 302 may be properly adjusted lengthwise of the shoe and angularly. To cooperate with this member there is provided another similarly curved clamp member 3I4 having thereon a lip 3 l6 arranged to enter a corresponding recess 3I8 in the member 302 to increase the frictional hold of the clamp members on the upper. The clamp member 3I4 is secured to two arms 320 which serve as a holder therefor, these arms having therein slots 322 through which the shaft 3l0 extends so that the arms may not only swing with the clamp mem- 5 her about this shaft but may also move lengthwise relatively to the shaft. Extending through the arms 320 is a rod 324 on which is pivotally mounted a block 326 which carries two springpressed pl-ungers 328 arranged to bear against l shoulders on the arms 320 above the rod 324.

These plungers tend to swing the block 326 downwardly about the rod 324 and position the block initially in engagement with shoulders 330 formed on tail portions 33I of the arms 320, 15 as indicated in Fig. '1. Pivotally connected to pins 332 carried by the block 326 in locations higher than the rod 324 are links 334 which are also connected to crank arms 336 fast on the shaft 3l0. Springs 338 connected to the pins 20 332 and to brackets 340 fast on the cover plate 290 tend to pull the block 326 and the arms 320 in a. direction lengthwise of the shoe away from the toe end of the shoe, and also tend to swing the block and the arms about the shaft 3l0 in '25 the direction to lift the clamp member 3I4 away from the member 302. Such movement of the block and the arms away from the shoe is limited by contact of the shaft 3l0 with the arms in the slots 322, and such swinging movement is limited by contact of the tail portions 33I of the arms 35 nor as to facilitate positioning the margin of the toe end of the upper in proper relation to the member 302.

Movement of the clamp member 3I4 into clamping position is effected by turning the shaft 40 3I0 in a clockwise direction (Fig. 7). At the beginning of such movement of the shaft the crank arms 336 act through the links 334 to move the block 326 and the arms 320 lengthwise of the shoe against the resistance of the springs 45 338 as far as permitted by the shaft 3l0 in the slots 322 of the arms, thus advancing the clamp member 3I4 lengthwise of the shoe before it begins its downward swinging movement. When such movement of the arms 320 is stopped by the '50 shaft 3I0 the links 334 begin to swing the block 326 and the arms about the shaft 3l0 to carry the clamp member 3 I4 into clamp-ing engagement with the upper, and after this member has engaged the upper the block 326 is swung, by further movement of the links, about the rod 324 against the resistance of the spring-controlled plungers 328, as illustrated in Fig. 11. The clamp member 3I4 is thus pressed yieldingly against the upper. The turning of the shaft 3I0 for the 60 purpose in view is effected by the operator through depression of a treadle 342 (Fig. 1) against the resistance of a spring 344, the treadle being connected by a flexible cable 346 to one arm of a lever 348 fast on the shaft 3l0. Pivot- 65 ally mounted on the other arm of this lever is a'finger 350 (Fig. 1) arranged to serve as a 'detent and controlled by a compression spring 352 (Fig. 5) which tends to swing the lower portion of the finger toward a lug 354 on the lever. Ini- 70 tially the finger 350 is held by the spring 352 with one side thereof in engagement with one end of 2. lug 356 formed on a plate 358 which is fast on one end of the previously mentioned rock shaft 252 (Fig. '1) whereby the toe wipers 75 are operated. When the operator depresses the treadle 342 to effect the clamping ofthe toe 'end of the upper the finger 350 is carried upwardly by the lever 348 past the lug 356, whereupon the spring 352 swings the lower end of the finger to a position over the top face of the lug, such swinging movement of the finger being limited by contact of the lug 354 on the lever 348 with the end of a screw 360 adjustably threaded in the finger. A lock nut 362 threaded on the screw 360 serves by engagement with the finger 350 to lock the to screw many adjusted position. When the finger 350 is moved to a position over the top of the lug 356 the clamp member 3I4 is locked by this lug in clamping position, so that the operator may remove his foot from the treadle 342. As the rock shaft 252 is turned to operate the toe wipers, after the depression of the shoe and the pullingsof the upper by the upper-clamping means, the lug 356 is carried out from under the lower end of the finger 350, thereby releasing the lever 348 and the parts controlled thereby so that the clamp member 3I4 is lifted to release the upper'and is returned to its starting posi tion by the-action of the springs 338. Preferably such release of the clamp member 3I4 is timed, by adjustment of thescrew 360, to occur just as the wipers begin to wipe the upper inwardly over the insole. 1

I As previously described, the downward move- I ment of the shoe within the toe band I82 is effected, in part, by the two presser feet I44 engaging the bottom of the heel-end portion of the shoe and operated by the downwardly movable carrier 36 on the rod 98. Cooperating with these presser feet is another presser foot 364 arranged 3 to engage the forepart of the insole over the toe rest 204, this presser foot being pivotally mounted as heretofore on a bracket 366 adjustable upwardly or downwardly on an arm 368 by a screw 310 threaded in a lug 312 on the arm. The arm 40 368 is supported by alined rods 314 and 316 (Fig.

1) mounted for vertical movements and for turn ing movements in bearings in the frame. The arm 368 occupies initially a position in which the presser foot 364 is retracted rearwardly from over the shoe bottom, and the operator swings the arm forwardly to position the presser foot over the shoe bottom by use of a handle 318 mounted on a lug 380 projecting forwardly from the arm. As fully described in Letters Patent No. 1,843,232, the machine is started inoperation by a forward swinging movement of the arm 368, whereupon the arm is carried downward simultaneously with the means engaging the heel end of the insole to effect'the depression of the shoe, the rod 98 at the heel end and the alined rods 314 and 316 at the toe end being, in fact, operated by the same cam.

From the above description it will be evident that in the lasting operation the position of the shoe with respect to tipping movement about any axis extending laterally thereof is determined by the cooperative action of the presser. foot 364 at the forepart and the two presser feet I44 at the heel end, and by suitable adjustment of the casting I68 (Fig. '7) along the guideways I10 the toe wipers 236, as hereinbefore explained, may be so positioned that they will extend lengthwise of the shoe in substantially parallel relation to'the forepart of the shoe bottom. To insure a substantially parallel relation between these wipers and the forepart of the shoe bottom in directions laterally of the shoe in the toe-lasting operation, the machine herein shown is provided with means for bringing the shoe into proper relation to the wipers, if it isnot already in that relation, by tipping it laterally through contact with the forepart of the shoe bottom. This means comprises a member 382 (Figs. 11 and 14) supported on the previously mentioned bracket 366 on the arm 368 and mounted to turn on a pin 384 on which the presser foot 364 also is mounted. The member 382 is provided with two downwardly projecting lugs 386 arranged to act on the forepart of the shoe bottom in spaced locations near the opposite side edges of the insole and to engage either the insole itself or a portion of the margin of the upper previously lasted over the insole, depending upon the condition of the shoe when it comes to the machine. The member 382 is controlled by two links 388 and 390 pivotally connected together by a pin 392, the link 388 being pivotally connected to the member 382 by a pin 394 and the link 390 being pivotally connected by a rod 396 to the bracket 366. A spring 398 (Fig. 15) connected to the link 388 and to the bracket 366 holds the links initially in alinement with each other as shown in Fig. l I, such positions of the links being determined by engagement of a shoulder 400 on the link 388 with a shoulder 402 on the link 390. When the links are thus positioned the member 382 is held rigidly thereby in a relation to the presser foot 364 such as illustrated in Figs. 11 and 14, the two lugs 386 projecting far enough downwardly to engage the bottom of the shoe in the downward movement of the arm 368 while the presser foot 364 is still a little above the insole. Such engagement of the lugs 386 with the shoe occurs before the presser feet I44 at the heel end arrive in shoeengaging positions, and if the shoe is not already in such position that the forepart of the insole extends laterally in substantially parallel relation to the plane of the toe wipers the shoe is tipped to the proper position by the action of the lugs 386 thereon. Such tipping of the shoe is facilitated by the mounting of the heel-pinsupporting block 2 in the guideways l8 (Fig. 13) as previously described, and although the heel end of the shoe is at this time clamped by the heel band 22, the yielding pressure of the heel band on the shoe is not such as to oppose substantial resistance to any tipping of the shoe that may be necessary for the purpose in view. Since the member 382 ordinarily performs its shoe-positioning function before the shoe is forced downwardly with any substantial pressure against the toe rest 204, the shoe as it is tipped will readily slip over the toe rest. In the construction herein shown, however, the rubber toe rest 204 is so supported on the plunger 206 that it may tip with the shoe, the toe rest being fast on a metallic member 404 (Fig. 14) provided with a depending curved rib 406 mounted in a similarly curved recess in the top of the plunger 206. Two spring-pressed pins 408 mounted in the upper end of the plunger 206 and bearing on the lower face of the member 404 maintain the toe rest normally in a centralized position.

After the shoe has been positioned as above described by the action of the member 382 thereon, control of the forepart of the shoe is transferred from the member 382 to the presser foot 364 and the member 382 is withdrawn from operative position, sinceif it remained in that position it would be in the way of the toe wipers 236 in their inward wiping movements. The withdrawal of the member 382 from operative position is preferably effected'prior to any substantial downward movement of the shoe and the toe rest 204; but since under some conditions the depression of the shoe and the toe rest may begin before the member 382 is withdrawn, the comparatively light spring 2l0 is provided as hereinbefore described in the plunger 206 to lessen the force of impact of the shoe against the presser foot 364 as compared with the force which would result from compression of the heavy spring 2l8 controlling the toe rest. It will be understood that such impact is due to the small space which must be taken up between the shoe bottom and the presser foot 364 when the shoe is released from control of the member 382.

To move the member 382 out of its operative position it is swung upwardly about the pin 384 through the links 388 and 390. To this end, the link 390 is fast on the rod 396 which is mounted to turn in a bearing in the bracket 366, and also fast on this rod is a bracket 410 in which is slidingly mounted a tubular member 4l2 having on its lower end a head 4|4 arranged to engage 2; lug 4 I 6 formed on one of the wiper-heating members 292. A spring M8 in the tubular member 4| 2 bears at its lower end on a pin 420 fast in the bracket and extending through slots in the member 2, and bears at its upper end on a screw 422 threaded in the upper end of the member 4I2. It will thus be seen that the spring 4l8 tends to move the member 4l2 upwardly in the bracket M0. The position of the member M2 in the bracket is determined by a lever 424 pivoted on the bracket and engaging the head of the screw 422, this lever being held in different adjusted positions by a spring-pressed pin 426 carried thereby and arranged to enter one or another of a plurality of holes 428 in the bracket 4l0. It will be observed that these parts are similar to those shown in Figs. 11 and 12 for variably controlling the plunger 88 which supports the heel wipers. It will be understood that the member 4| 2 is preferably so adjusted that its head 4 engages the lug 416 just as the shoe is properly positioned in the manner hereinbefore described by the member 382, and that in further downward movement of the arm 368 the rod 396 is turned by the action of the lug M6 on the member 4l2 so as to swing the links 388 and 390 out of alinement with each other, as illustrated in Fig. 15. In the return of the parts to starting positions the spring 398 swings the links again into alinement with each other and thereby positions the member 382 in proper relation to the presser foot 364. 1

Supported on the arm 368 is also means differing somewhat from that disclosed in the previously mentioned Letters Patent No. 2,026,539 for pressing the margin of the toe end of the insole close to the bottom of the last and for also engaging the margin of the upper to assist the toe wipers in wiping the upper tightly and smoothly over the insole. This means comprises a clamp member 430 (Figs. 1 and 11) curved for engagement with the margin of the insole around the toe end and pivotally mounted on the lower end of a yoke member 432 having upwardly extending arms 434 and 436 (Fig. 14). The arm 434 is pivotally supported on one end of an arm 438 which is secured at its other end to a rock shaft 440 extending through the arm 368, and on the other end of this rock shaft is an arm 442, a portion of which is visible in Fig. 14, this arm being connected to the upwardly extending arm 436 of the yoke member 432. Connected to the arm 438 by a link 444 is a plunger 446 pressed down by a spring 448 (Fig. 11) mountedin the handle 318, the downward swinging movement of the arm 438 being adjustably limited by a screw 456 threaded therein and engaging a lug 452 on the arm 368. The yoke member 432 is further controlled by a link 454 connected to its arm 436 and to an eccentric 456 formed on a pin 458 mounted to turn in the arm 366 and adjustable by means of a screw driver to vary the position of the clamp member 436 lengthwise of the shoe. It will be understood that the clamp member is so adjusted heightwise of the shoe by the screw 456 that when the presser foot 364 is in engagement with the insole the clamp member is under control of the spring 446 which holds it pressed yieldingly down upon the insole. The clamp member is provided with an outwardly inclined face 466 against which the margin of the upper is pressed by the wipers 266 as the Wipers begin to wipe the upper inwardly over the edge of the insole, and by wedging action of the upper and the wipers against this inclined face the clamp member 436 is lifted against the resistance of the spring 448 to permit the wipers to wipe the upper inwardly beneath it, as illustrated in Fig. 16.

As in prior machines of the illustrated type, the toe wipers 236 are operated to wipe the margin of the upper inwardly over the insole at substantially the same time as the heel wipers 26, and near the end of the inward wiping movements of the toe and heel wipers the heel presser feet 144, as previously described, are released by the latch 56 uo permit the heel end of the shoe to be pressed more firmly up against the heel wipers by the action of the spring 16 on the slide i4. Any

actual upward movement of the slide 14 and the heel end of the shoe at this time is, however, Very small, since the wipers 26 are held against up-. ward movement by the arms 122. Thereafter, in order similarly to increase the pressure of the toe wipers on the overwiped margin of the upper, both the arm 368 which carries the toe presser foot 364 and the carrier 66 on which the arms 522 are supported are moved upwardly by their operating cam, as described in Letters Patent No. 1,843,232. This permits the spring 218 controlling the toe rest 294 to press the toe end of the shoe more firmly up against the toe wipers. It will be evident, however, that any actual upward movement of the toe end of the shoe is very small because of the resistance of the toe wipers. Since the arms i2"? which press down on the heel wipers are necessarily moved upward with the carrier 96, the heel end of the shoe might, unless prevented, be moved far enough upward by the action of the spring IS on the slide 14 to tip the forepart of the shoe relatively to the elongated toe wipers so as to decrease the pressure applied by the latter at the extreme toe end of the shoe. The machine is accordingly provided with means for limiting or preventing such upward movement of the slide 14 when the carrier 96 receives its upward movement. For this purpose there is secured to the upper end of the slide 14 (Figs. 1, 19 and a bracket 462 on which there is mounted a small vertically movable slide 464 provided with ratchet teeth 466 arranged to cooperate with a pair of pawls 466 which are carried by an arm 416 of the previously mentioned bell-crank lever 66 the arm 18 of which imparts operative movement to the heel wipers 26. The two pawls 468 are arranged in staggered relation for greater precision and are mounted to turn on a pin 412 on the arm 416. The pawls are controlled'by a lever 414, also mounted to turn on the pin 412,

through springs 416 mounted between an upwardly extending lug 41.8 on the lever and upwardly extending tail portions of the pawls, each of the pawls carrying a pin 486 which extends through the spring and through an opening in the lug 416 and which carries nuts 482 for limiting relative movement of the lever 414 and the pawl under the influence of the spring. A spring 464 connected to one end of the lever 414. and to the arm 416 tends to swing the lever in a'counterclockwise direction (Fig. 19), such movement of he lever being limited by engagement of a pin '26 thereon with the lower face of the arm 410. he lever 414 carries at one enda screw 4B8 arranged engage the head 466 of a rod 492 slidingly mounted in lugs on the bracket 462 and ranged to; rest at its lower end on a'shoulder 4 on the frame of the machine. Accordingly, the bell-crank lever 86 is operated to advance and close the heel wipers, the arm 416 near the end of the wiper operation carries the screw 488 into contact with the head 499, whereupon the pawls 466 are swung yieldingly into engagement with the ratchet teeth 466 through the action of the lever 414 on the springs 416 as the arm 4111 continues tomove downwardly. In this manner the small slide 464 is locked against upward movement. This locking of the slide 464 occurs just before the presser feet 144 are released by the latch 156; and in order to permit the shoe to be. pressed more forcibly up against the heel wipers by the spring 16 when the presser feet are thus released, there is provision for limited upward movement of th slide 14 relatively to the small slide 464. To this end, the slide 464 is slidingly mounted in a vertical guideway in the bracket 462. Extending laterally from the upper end of the slide 464 is a lug 466 underneath which is a spring 498 mounted in a recess in the. bracket 462, and extending laterally from the lower end of the slide is a lug 566 in which is mounted a screw 502 arranged to engage a shoulder 5114 on the bracket. The spring 468 normally holds the slide 464 in a position determined by the screw 562, the screw being so adjusted that there is a small space between the lug 496 and the top of the bracket 462. This permits a short upward movement of the slide 14 to increase the pressure of the shoe on the heel wipers at the time when the presser feet 144 are released by the latch 156. By such upward movement of the slide 14 the space between the lug 496 and the bracket 462 is substantially or nearly taken up, so that when the carrier 96 is thereafter raised with the arm 368 to permit the toe end of the shoe to be pressed more firmly up against the toe wipers, but little, if any, upward movement of the slide 14 can take place by reason of engagement of the bracket 462 with the lug 496 on the slide. 464 which is locked against upward movement by one or the other of the pawls 468.

The power driving means in the machine herein shown, and the mechanism for starting the machine and for automatically stopping it at the end of the cycle, are substantially the same as disclosed in Letters Patent No. 1,843,232 and will be only briefly described. As shown in Fig. 2, there is an electric motor 506 connected by a chain 508 to a shaft 510 having thereon a worm 512 for driving continuously a worm gear 514 mounted to turn on a cam shaft 516. The gear 514 serves as a clutch member cooperating with another clutch member 518 fast on the cam shaft 516. Thetwo clutch members are connected together to drive t e machine by the turning of a cylindrical member 528 (Fig. 17) in the member 5l8 by a spring 522 connected to an arm 524 fast on the outer end of the member 528. The inner end of the member 528 is recessed on one side to clear normally a series of teeth 525 carried by the gear 5M, and when the member is turned by the spring 522 a portion 526 thereof is moved into the path of these teeth to cause the gear 5|4 to drive the member M8. The member 528 carries a pin 521 normally engaged by a plate .528 on a lever 538 to disconnect the clutch members 514 and 518. Ihe lever 538 is lifted to release the pin 521 and start the machine through a hook 532 connected by mechanism including a link 534 to the previously mentioned toe presser foot arm 368. When the arm 524 is operated by the spring 522 to connect the two clutch members it is locked against reverse movement by a spring-controlled lever 536 mounted on the clutch member 5I8 and having therein a notch 538 to receive a projection 539 (Fig. 17) on the arm 524. After the starting of the machine the lever 538 is released from the hook 532, to permit the plate 528 to be returned into the path of movement of the pin 521, by a finger 548 fast on the clutch member 518 and arranged to engage the lower end of the hook 532. The lever 536 is engaged by a lug 542 on the plate 528 to release the arm 524 just before the pin 521 arrives in position to engage the end of the plate 528, after which this plate acts through the pin to disconnect the two clutch members and stop the machine at the end of the cycle of operations.

The machine herein shown is provided additionally with means for bringing the machine to a stop at a point in the cycle immediately after the shoe has been pressed more firmly upward against the toe wipers 235 by the action of the spring 218 under the toerest, as hereinbefore described, and for again starting the machine automatically after a variably predetermined interval. This renders the toe wipers more effective to press the upper free from wrinkles and to transmit their heat to the adhesive for accelerating the drying out or hardening of the adhesive. For thus stopping the machine, there is mounted on a bracket 544 on the base of the machine a lever 546 having fast thereon an arm 548 provided with a shoulder 550 for engaging the pin 521 and disconnecting'the two clutch members and provided also with a. shoulder 552 for operating the lever 536 to release the arm 524. The lever 546 is controlled by a spring 554 which holds the arm 548 normally with its shoulder 558 in the path of the pin 521. The arm 548 is swung downwardly to start the machine again by an automatic timing device including a bar 556 which is reciprocated periodically at all times in downward and upward directions by means hereinafter described. This bar is guided by two plates 558 (Fig. 18) which are secured to the arm 548 and by a bolt 568 mounted in the plates 558 and lying between a portion of the bar 556 and a plate 562 fast on the bar. Formed on this plate are ratchet teeth 584 engaged by two pawls 566 which are mounted to turn on a bolt 568 in the plates 558, the pawls being arranged in staggered relation for greater precision. Each pawl is controlled by a spring 510 which tends to hold it against the ratchet teeth. Normally, however, the pawls are held out of engagement with the ratchet teeth by a small bell-crank lever 512 mounted to turn on a pin 514 carried by the plates 558 and provided with screws 516 arranged to engage tails on the pawls to swing them away from the ratchet teeth against the resistance of their springs 518. The bell-crank lever 512 is held in position to disconnect the pawls from the ratchet teeth by a spring 518. Substantially at the time, however, when the arm 548 acts on the pin 521 to stop the machine the previously mentioned finger 548 on the clutch member 5l8 engages the bell-crank lever 512 and swings it far enough to release the pawls 566 and permit them to engage the ratchet teeth 564. Thereafter, each downward movement of the bar 555 results in a corresponding downward swinging movement of the lever arm 548 by reason of the fact that the ratchetteeth 564 tend to turn the pawls 566 in a counterclockwise direction (Fig.

17) and thus to cramp them against the plate 562. The arm 548 is locked against reverse upward movement by teeth 58!) on the finger 548 in engagement with a tooth 58! on the bell-crank lever 512, the finger 540 thus serving as a detent. As the bar 556 receives each upward movement the teeth 564 are carried past the pawls 566 by reason of the fact that the pawls are turned by the teeth in a clockwise direction. It will thus be seen that the arm 548 is moved downward step P by step until the shoulder 558 on the arm passes beyond the end of the pin 521, whereupon the machine is started again in operation. Just as the shoulder 558 passes beyond the end of the pin the bell-crank lever 512 also passes beyond the end of the finger 548, whereupon the spring 518 swings the bell-crank lever into position to disconnect the pawls from the ratchet teeth and the arm 548 is returned upward to its normal position by the spring 554.

For imparting to the bar 556 its repeated downward movements there is provided a cam member 582 (Figs. 2, 3 and 4) fast on a shaft 584 which is driven continuously and serves to operate a belt conveyor 586, as disclosed in Letters Patent No. 1,843,232. This cam member engages a roll 588 mounted on a lever 598 which is pivoted at 592 on a bracket 594 on the frame and is connected by a rod 598 to the bar 556. The cam member 582 is a substantially square member, as shown in Fig. 4, so that it imparts four downward movements to the lever 598 and the bar 556 in each revolution of the shaft 584. After each downward movement the bar and the lever are returned upwardly by a spring 598 connected to the bar. The limit of upward movement of the lever 598 is variably determined by a cam 688 which engages the upper face of the lever and is fast on a shaft 682 mounted in the bracket 594, the shaft having also fast thereon a crank arm 684 for turning it and thereby adjusting the cam. The cam 688 is held in adjust-ed position by a spring-pressed pin 686 mounted in the arm 684 and arranged to enter one or another of a plurality of holes 688 in the bracket 594. It will thus be understood that by adjustment of the cam 688 the amount of downward movement imparted each time to the lever 598 and the bar 558 may be Varied so as to vary the number of downward movements of the bar required to move the arm 548 downwardly far enough to start the machine. Accordingly the length of time that the heated wipers remain in contact with the overwiped margin of the upper may be varied at will.

The character of operations previously performed on a shoe to be operated upon by the above-described machine will vary in accordance with the preferences of different manufacturers. In Fig. 24 is shown, for example, a shoe which after the customary assembling and pulling-over operations has been lasted along the sides with the well-known Littleway staples s, the rows of staples extending forwardly of the ball line but terminating in locations somewhat short of the toe portion of the shoe so as to leave not only the toe portion but also a portion of the shoe extending rearwardly therefrom toward the ball line to be lasted with adhesive. Suitable adhesive will preferably have been applied to the heel end of the insole and to the margins of the heel end of the upper materials prior to the assembling operation; and such adhesive may have been applied also at the forepart before assembling, or may be applied in this location just before the shoe is presented to the illustrated machine. Preferably also at the toe end the layers of the upper materials, with the exception of the outer layer, will have been so out prior to assembling, or will be so trimmed before the shoe is presented to the machine, as to extend but little inwardly from the extreme edge of the insole when in lasted position.

After mounting the shoe on the shoe support the operator releases the slide 24 which carries the heel band 22 and the heel wipers 26, as customary in the use of machines of the illustrated type, whereupon the spring 28 moves the slide toward the shoe and the spring 30 moves the shoe back against the heel band, as hereinbefore described. The operator then spreads the margin of the toe end of the upper outwardly over the lower clamp member 332 and by use of the treadle 342 moves the cooperating clamp member 314 from its idle position into clamping relation to the upper. The clamp member SM is locked in clamping position by engagement of the lug 356 i with the lower end face of the finger a. Thereafter the operator swings the arm 368 forwardly by the handle 3'18, this movement of the arm resulting in the starting of the power operation of the machine.

Upon the starting of the machine the arm 368 begins its downward movement, and the carrier 96 at the heel end is swung to carry the presser feet I44 into position over the heel end of the shoe bottom and is also moved downwardly. Before the presser feet M4, however, engage the shoe the member 352 carried by the arm 368 arrives in position to engage the bottom of the forepart of the shoe and to tip the shoe laterally into proper relation to the toe wipers if it is not already in that relation. Immediately thereafter, in response to continued downward movement of the arm 358, the member 382 is swung upwardly and control of the forepart of the shoe is thus transferred to the presser foot In the downward movement of the carrier 52%;, just after the shoe has been properly positioned by the member 382, the presser feet I44 arrive in positions to engage the heel end of the shoe and are acted upon by the shoe to tip the heel wipers laterally into proper relation to the heel seat in the manner previously described, these wipers 7 being positioned at the proper height relatively to the heel seat by the arms 522. Continued downward movements of the arm 358 and the carrier 96 serve thereafter to depress the shoe, the heel wipers and the heel band being moved downwardly with the shoe. In response to such depression of the shoe the toe-end portion of the upper is wiped upwardly'by the toe band I82 and is also subjected to a pull by the action of the means which clamps its margin, the upper being permitted to slip more or less between the clamping members 302 and 314. As the shoe is forced down within the toe band the toe wipers are adjusted in accordance with the lateral swing of the forepart of the last under control of the toe band, in the manner previously described. At the end of the downward movement of the shoe the parts which operate at the forepart of the shoe are in the positions illustrated in Fig. 15, the margin of the toe end of the insole being pressed down on the last yieldingly by the member 43!! carried by the arm 368.

The toe and heel wipers are next operated to wipe the margin of the upper at the toe and heel ends inwardly over the insole. Substantially at the time when the toe wipers arrive ,at the edge of the insole the clamp member 3M is released by movement of the lug 356 out from under the finger 350, and as the wipers continue their inward movement they press the marginal portion of the upper against the insole-engaging member 439 which thus acts as a retarder on the upper, this member being forced upwardly by the wedging action of the wipers and the upper thereon and then assuming a position over the wipers, as illustrated in Fig. 16. As the heel wipers 23 are advanced and closed over the heel seat they move the presser feet I44 more or less forwardly, and nearthe end of the inward movement of the heel wipers these presser feet are released by the latch I56 to permit the heel end of the shoe tobe forced more firmly up against the wipers by the action of the spring IS on the slide 14. Thereafter the arm 368 and the carrier 96 are moved upwardly a short distance to permit the forepart of the shoe to be forced more firmly up against the toe wipers by the action .of the spring 2|8 on the toe rest 2, any substantial upward movement of the heel end of the shoe at this time being prevented by the pawl-and-ratchet mechanism shown in Fig. 19.

After the shoe has been forced upwardly against the heated toe wipers asabove described,

the machine is brought automatically to a stop by the mechanism shown in Fig. 17 to permit the overwiped margin of the forepart of the upper to remain for a short time under the pressure of the toe wipers and under the influence of the heat transmitted therefrom. It will be understood that these wipers may overlap more or less portions of the forepart of the upper previously I lasted with staples, these previously lasted portions accordingly being subjected to an ironing action by the wipers. After an interval variably predetermined by adjustment of the automatic controlling mechanism shown in Figs. 2 and 17 the clutch is actuated to start the machine again in operation, whereupon the arm 368 and the Features of the mechanism herein disclosed for,

bringing the machine to a stop prior to the completion of its cycle and for automatically starting it again are claimed in a divisional application Serial No. 72,860, filed on April 6, 1936.
