SPECIFICATION forming part of Letters Iatent No. 436,852, dated September 23, 1%890. Original application filed July 13, 1839I Serial No. 3171.443. Divided and this application filed December 10. 1889; Serial No.

To all whom it may concern:

Be it known that I, IsAAo N. FORBES, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and usefullmprovements in Lasting-Machines and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in various parts of the machine with a View to simplifying, lightening, and cheapening its conl struction, while at the same time increasing the convenience and efflciencyof its operation.

My invention consists in those parts and combinations thereof, or their equivalents, which are hereinafter set forth and claimed.

With regard to the side-lasting clamps and holders therefor this application is a division of that filed by me July 13, 1889, Serial No. 317 ,443.

Referring to the drawings, A indicates the table, designed especially to meet the various requirements of this machine, both for the support and adjustment of the various parts of the frame and mechanism and for the reception of the detachable and interchangeable parts when not in use. The table is provided around its edge with a depending flange a; transverse bearing-plates a a. d2 a2, situated below the top of the table and within the flange at; horizontal perforated end-clamping anges a3, joined to the lower edges of flange a and plates a2; lateral extensions A A to accommodate and inclose the side-lever mechanism, and having depending flanges a4 and horizontal transverse guides c5; verticallyperforated bearing-bosses a6 a, depending from the top of the table and eccentrically situated, as shown in Figs. l and 46; a longitudinal central enlargement a7 formed. upon the under side of the table-top and containing the longitudinal T-groove as, and a central depending transversely-perforated bearing-bracket a9. All these parts are preferably formed by a single casting, although they may consist of several parts bolted together. The table top is vertically and centrally slotted-transversely, as indicated at am d10, and longitudinally, as shown at au al1-to admit of the passage and working of the side and end lasting levers. The middle portion of groove cts-is enlarged, as indicated at @12, and the lower and wider part of the same is still further and circularly undercut at @13, as indicated by dotted lines, Fig. 34, and the flange a is cut away at am a, opposite the extension A to admit the side-lever-actuatin g mechanism.

A2 A2 indicate the legs of the table, Figs. 1 and 8. They consist of castings of a width equal to that of the main portion of thetable,

provided with side Hanges 0.15, which extend from the end of the table tothe plate a2, with horizontal perforated top flanges am, which extend the same distance and are secured to the under side of flanges as by bolts a, and with other horizontal anges 0.18, situated at Various heights and supporting sheet-metal shelves A3, which have upturned edge flanges d, fastenedby rivets or screws d20 to the vertical portions of thelegs. These shelves serve to hold the interchangeable parts of the machine within convenient reach ofthe operator, and sodisposed that the desired part may be readily selected.

It is highly important that the operator ot' each machine have under his absolute control the interchangeable parts of his machine, not only conveniently arranged and within easy reach, as already mentioned, but so secured that in his absence other persons may not borrow or abstract these easilyportable pieces. This despoiling of a machine is always a source of annoyance and delay, and is sometimes resorted to for the purpose of bringing a particular workman or type of machine into disrepute. I have therefore provided the working parts of the machine with a substructure which is in effect a metallic safe, within which the detachable parts of the machine may be not only conveniently but securely stored. Referring to Figs. to 74, A4 indicates horizontal longitudinal supporting-pieces, which are provided with vertical and horizontal flangesa21 C022, the latter of which are situated beneath the front and rear edges of the bottom shelf, Figs. 67 and 7 2, and support the same. sheet metal, may be made plain, as shown in most of the figures, or may be longitudinally corrugated for the sake of additional strength and stiffness, as shown in Fig. 7 3. If desired, the shelves may be stilened around their edges by metallic frames A5, around which the edges of the shelves are bent, as indicated in Fig. '74. On its rear side the table-top is suitably rabbeted at @23, and the rear sides of the table-legs are similarly rabbeted at @24, Figs. 46 and 67, and in the recess thus formed is fitted a sheet-metal panel A6, which may be embossed or struck up, as indicated, to give greater strength and add to the appearance of the structure. At its base the panel A6 is screwed or riveted to the rear piece A4, Fig. 67. I may here state that in securing the different parts of the table and legs together screws or rivets will be employed, accordingly as is desired to produce a structure which may be taken apart for purposes of transportation or one which is permanent. On its front side the table and legs are similarly rabbeted at @25 ag, in which recessis seated a door A7, preferably made in two parts, hinged to the legs at A8. By means of a lock A9 this door may be securely fastened, so that it can be opened only by the workman having charge of the machine, who may thus at all times have the interchangeable and portable parts of the machine under his personal control. The under sides'ot' the extensions A are closed by plates A10, Figs. 65 and 66, secured by screws which enter the apertures L27 formed in the iianges a4, Fig. 46.

Last-slfafndswB is the heel-stand for the These shelves, ofv

last C, inwhich I provide for adjustments of the last longitudinally, laterally, vertically, and angularly in horizontal planes, according to the size of the last and the situationin the` last of its heel-stand socket. I prefer to fit the latter with ametallic lining or bushing c, Fig. 8, for the sake of durability and in order that the last may always fit the stand accurately and be iirmly supported. B Ais au internally-screw-threaded sleeve having at its upper end a cylindrical vertical pivot b, adapted to lit the bushing c and permit the horizontal angular adjustment of the last. At the base of said pivot is a supporting-flange h', and the last may also be supported by the abutting of the pivot against the closed end. of the socket c. Above the internal thread is a cylindrical bearing h2, Vwhich is accurately fitted by a pin b3, carried at the upper end of a post B2. The latter has an external screw-thread b4, which lits -feely the correspondingl internal thread of the sleeve B, and below the thread a cylindrical journal b5, which accurately fits a corresponding bearing h6 in the lower part of the sleeve. The last may be vertically adjusted by screwing sleeve B up or down, while the accurately-fitting bearings at each end of the thread prevent any looseness of the last, although the screwthreads do not fit each other tightly.. The lower end of the post B2 is provided with a lateral flange 67 and below the iiange with a T-head 68, which is adaptedto t a corresponding transverse groove b9 in a base B3, and may there be secured when the post has been adj usted laterally, as desired, by a setscrew blo. For the sake of compactnessand in order that the `heel-stand may be more firmly held in place, I have provided the base B5 with a central clamp below the T-groove b9 and substantially in line with the post B2. To this end the base is formed with a central chamber closed on the lower side by a screwplug hu, having a central vertical opening, through which passes a stem B4, which is screw-threaded near its upperend and has on its lower end a T-head 1712, Fig. 13, adapted to pass down through the enlargement cd2 of the groove @got the table and to fit Within the groove. Above its screw-thread the stem B4 lits at 1913 in a corresponding bearing in the said base. A combined worm-wheel and nut B5 fits upon the thread of the stem B4 within the base, and bears upon the 'upper side of plug hu, while its toothed periphery is engaged by a horizontal transverse worm B, Fig. 20, which is mounted in suitable bearings in the base and provided at its end neXt the operator with a milled head h and squared head b, by which it may be turned' (by hand or key) toA rotate the wheel-nut B5, raise the stem B4, and vclamp the base B3 to the table.

In order to guide lthe base andv IOO IIO

. plug b is correspondingly shaped.

l l larged toward the bottom, in order to be strong enough for its considerable height, and is at its base provided with a T-head d', adapted to fit said groove. Above this head the post is screw-threaded at d2 and engaged by a handled nut D3, which bears upon a washer D4, the latter in turn resting upon the top of the table. It will thus be seen that the toestand may be readily adjusted longitudinally and clamped in place and made of the proper height, according to the size of' the last which is to be supported opposite to the lasting'devices. At its top the sleeve D' has a vertical pivot d3, upon which swivels a suitable toe-rest D5, adapted to support and keep the forward end of the last in proper position.

Head-yoke.-E E indicate two ,yoke and side fulcrum stands, mounted at the sides of the table upon the extensions A' and secured rigidly in place by vertical bolts e, the heads and nuts of' which engage the under side of the table-top and the upper surfaces of the horizontal flanges e' of the stands. With said flanges and the outer walls of the stands are cast horizontal transverse bearings e2, which are vertically and longitudinally slotted and provided at their outer ends with internallyscrew-threaded bushin gsE' ,which are screwed in place in the stands, Figs. 1 and 34. Above the flanges e the standsl E extend outwardly and upwardly, Fig. l,being U-shapedinhorizontal cross-section, with the open or concave side inward, and are at their tops formed with horizontal flanges, in which are cut internal screw-threads which engage correspondingly threaded and Iianged stems e3 e". 'lhe latter form the bases ofposts E2 E3. The former constitutes a vertical pivot, upon which fit the sleeves ff' ot' the hinge-piece F of' -the head-yoke F', which sleeves rest upon the iiange c5 of the post and are engaged by a nut e6, screwed upon the upper end of the post, respectively. The hingepiece has two inwardly-extending ears f2, between which the yoke F fits, and on which it is mounted by means of' a horizontal hinge pin or bolt f3, which fits both of the parts neatly, and by a stop pin or bolt f4, which fits in the ears of the hinge-piece and engages a slot f5, formed from pin f3 as a center, in the yoke F'. F2 is a plate-spring mounted between the ears f2 on a pin f6, engaging by its free end a notch f7 in t-he yoke, and bearing between its ends and by its inner face against a pin f8. These parts are so adjusted that the spring Fzphas the necessary tension to lift the yoke F', with its head and pliers, (when the latter are disengaged from the upper,) oscillating the yoke upon pin f3 upward and out` ward until the inner end of slot f5 strikes the stop-pin f4. Vhen thus lifted, the yoke, with its head, may be swung easily upon post E2 from over the last to the position indicated by dotted lines in Figs. 1 and 8, thus affording ready access for securing the upper and removing the lasted shoe. The severe lifting strain imposed upon the workman by the ordinary upwardly-turning head is thus entirely obviated. At the side of the machine opposite to the yoke-hinge the yoke is provided with an outwardlyextending rigid handle f 9, with a tapering or conical proj ection f 10, which is adapted to come over and fit a correspondingly-shaped seat e7 in the upper end of the part E3, and with a latch F3, hinged by pin f to the yoke. Below the seat e7 the post is formed with a socket adapted to contain a rubber or other elastic buffer es, which the projection f 10 will strike and compress as the yoke is forced down into place by the latch. For this purpose the latter is swung inwardly on pin f11 bymeans of the handle fm, thereby causing roller fw, which is journaled on the latch, to engage the outer lower edge of a projection e, form ed on post E3, and to roll under said projection. This movement brings the yoke, with its downhold, firmly down into place and securely locks it. A reverse movement of the latch permits spring F2 to lift the yoke, as already described, sufficiently for the downhold to clear the last, projection f10 to clear the post E3, (see Fig. 3,) and the pliers to clear the lasting devices. A spring f, Fig. 3, is seated in a dovetailed recess in the headyoke and secured by a screw f 15. Its free end,

covered with rawhide or other suitable material, fw, extends downward to a point where it will strike the round (or flat) post E3 and prevent shock when the yoke swings horizontally into place.

Dcwnholrl.-G is the downhold comprising a head g, adapted to rest upon the inner sole and swiveled upon a screw-threaded stem g. The latter engages and is vertically adjustable in the horizontal arm g2 of a bracket G', which latter has a journal g3 fitting a vertical bearing f1@ in the arch f17 of the head-yoke. At or near the upper end of said journal it is screw-threaded and engaged by a nut g4, by which the bracket G' can be securely clamped to the yoke, with the arm g2 in any desired position.

Heart-The pliers are so supported that after they have been engaged with the edge of the upper they may all be raised at once to draw the upper tightly over the last. The toe-pliers are, moreover, separately mounted, so that they-say three in number-may be independently raised to stretch the upper sufficiently along the instep and around the toe. F4 F4 are inwardly-extending vertical guides formed with the head-yoke F', Figs. 47 and 56, and engaging corresponding vertical grooves h, formed in the central piece H of the head, Figs. 57 and 58. Said piece has formed with or secured to it a vertical stem or shank IOO IIO

H, Fig. s.

H, on Vthe upper end of which is formed a screw 7L', adapted to engage a correspondingly-threaded nut I. The latter is mounted and rotary in a vertical bearingsleeve F5, wi th which the central part of the head-yoke is provided, resting upon a washer i', and being held in place by transverse pins fm, which pass tangentially through the sleeveand engage a peripheral groove iin the nut. Below the screw the stem H has a round portion h2, of the same diameter, which accurately lits and is adapted to slide verticallyin the lower part of the sleeve F"",Fig. l. By means of the crank-handle I the nut I may be readily turned in horizontal planes and the piece H and all parts carried thereby, including the pliers, raised vertically. Said piece is formed with three perforations,Fi gs. l5 and 58,the central oneh3 of which is screw-threaded and receives alongitudinal bearingsleeve H2, which is screwed in place therein and keyed in place by a pin 7L, which is driven or screwed up through the bottom extension hl2 of the piece Said Vextension serves as a stop adapted to abut the upper end of journal g3 and arrest the downward movement of the head, thus preventing screw 7L from becoming disengaged, Fig. S. The outer h4 h4 of the said perforations receive and rigidly hold longitudinal shafts H3 H3, Figs. 9, ll, 12, and 47, each of which has alongitudinal groove h5. Above the perforations h4 the piece H has two other perforations h6 7i, Fig. 58, in which are carried two longitudinal oscillatory shafts H4 H4,

plates mounted upon the ends of shafts H3 H4 l sion is put upon the pliers.

and additionally connected by means of screwrods H6 H6, Figs. 8, 9, and 47. Said end plates are also provided with inwardly-extending sleeves hs, which fit neatly around the ends of the central bearing-sleeve H2. The shafts H4-are adapted to turn in their bearings in the parts H and H5. Upon shafts H3 are mounted longitudinally-movable sleeves H7, Figs. 9 and l2, which are kept from turning by pins hf 71,9, with which each of said sleeves is provided, and which enter the groove h5.

Hangers and pliers-Each of the sleeves H7 supports a side plier, the hanger-eye J of which surrounds the sleeve between pins hf, by which latter the eye is kept in place. By sliding the sleeves by hand alongtheir shafts the side pliers may be properly distributed to operate upon the upper of a long or short shoe. The lower ends of eyes J have screwthreads j, upon which are vertically-adjustable screW-sleeves J Fig. 75. Into the lower ends of said sleeves are rigidly screwed pins J 2, the heads j of which iit within the hangersleeves J 3. Above said heads and below the upper ends of the sleeves are springs J 4, through the medium of which an elastic ten- The sleeve J3 has downwardlyextending legs j?, the space jaws are made narrow at their operative ends. Between said legs are hinged the plier-jaw and leg pieces K K by means of a screw-pin k, which carries a sleeve le and iits into eyes jg, formed on the ends of legs 3'2. The sleeve it fits in eyes 7a2, formed on the plier-pieces just above the jaws 7c3 and below the springlegs 7a4, Figs. 75, 84, and S5. The eye k2 is onehalf the width of the plier-piece; but the other half of the piece is provided with a semicircular bearing 7t5, of a radius equal to that of the outer periphery of the eye c2of the other plier-piece and adapted to fit the latter-,whereby, although the pieces are in line with or opposite each other when fitted together, each plier-piece has a bearing for its full width. Moreover, the piece is much strengthened by the wall which forms the bearing R5 and connects the jaw with the spring-leg. portion of the outer piece K is formed like that of the inner piece K', excepting that the jaw and leg are not so nearly in line, Fig. 85, thereby throwing the plier-handle out into a convenient position and enabling the leg of The lower l v the inner piece K to remain nearly perpendicular and still give the desired distance between the legs when the plier is closed, Fig. 77. At the upper ends of the plier-pieces are formed eyes 7n k7, which are hinged by pins ks to two elbow-levers K2 K3. The latter are` hinged together by pin ki. The lever K2 is divided vertically at its inner end, and its two arms 7010 pass one on each side of the eye k7 and receive the pin ks thereof. At its other end said lever receives between its arms the lever K3, Fig. 80, which latter at its outer end is forked or divided to receive the eye los. This eye is consequently thinner than the eye k7 of the piece K. rlhe outer extremity of lever K2 is prolonged, bent slightly downward, and forms a handle by the depression of which the spring-arms may easily be forced apart and their jaws caused to seize the edge of the upper. .l5 is a stop-pin passing transversely through and fixed in the hanger-legsl between the spring-plier pieces 1.94, andf at such height to arrest the downward movement of the elbow-levers when the pin 7st has reached a point slightly below a straight line drawn between pins 158. The levers are thus self-locking. The elasticity of legs 7a4 permits this locking to be easily effected, notwithstanding the varying thickness of the uppers. The pins J2 are of different lengths, those carrying the pliers at the ball of the last beingthe shortest, Fig. 8.

PLier-detach'ing devices-Upon each of the shafts H4 are mounted a series ot' levers L, one for each side plier. Said leversare provided with vbearings Z, which encircle the shafts, and which are partially divided or split, so as to `be compressible by bolts Z. They may thus be made to fit said shafts ac-4 curately. The levers may be moved longitudinally upon their shafts and kept' in line with the side-pliers, but are prevented from turning by pins Z2, which engage the'grooves IOO IIO

k7, Fig. 1. The oscillation of each shaft H4 thus causes all of its levers L to turn simultaneously, and the outer ends of the levers being connected by cords, chains, or wires L with the pins kg of the plier elbow-levers the latter may be lifted and all of the side pliers disengaged at once from the upper by suitable movements of said shafts. That one of the shafts H4 which is on the side of the machine next the operator is provided with a hand-lever L2, which may be conveniently formed in one piece with one of the levers L, and the movement of this shaft is caused to produce a simultaneous opposite turning of the other shaft H4 by means of intermeshing toothed segments L3, Figs. 1 and S, mounted on said shaft.

Toe-pliers -The toe-pliers 7a4 and hangers J 6 are similar to those for the side of the last, excepting that they are suspended by screwhooks J7, which engage and oscillate freely in eyes M, secured to a plate M', Figs. 8, 47, 48, and49. Thelatter is attached to or formed with a vertical sleeve M2, which has at its upper end an internal flange m, engaged by an external flange m, formed on a vertical screw M3, Fig. 8. This screw engages by its thread a screw-sleeve M4, formed with a horizontal longitudinal slide-shaft M5, which iits within the forward end of the central sleeve or tube H2 of the head. Shaft M5 is longitudinally ladj ustable therein for a long or short last, but is held from turning by short pins hw, Fig. 8, which are driven or screwed into sleeve H2 and extend inwardly into the longitudinal grooves m2. of the shaft. M6 is a crank-handle by which screw M3 may be operated to raise or lower the screw and with it the sleeve M2 and plate M. The toe-pliers may thus be addiiionally raised relative to the side-pliers. The sleeve M2 is cut away at its rear at m3 in Fig. 48 to accommodate the shaft At its upper end the said sleeve is provided with a rearwardly-proj ectin g bracket M7, Figs. 48 and 50, to which is hinged by a pin m4 the forked arms m5 of a hand-lever M8. In front of the sleeve said lever is connected by a depending link m6 with an ear m7, securedto a plate M9. This plate has a vertical sleeve m8, which fits around and slides upon the sleeve M2, and is perforated in three places, as shown at m", for the attachment of the flexible connections or wires L4 of the toe-pliers. Said connections operate in the same manner as the side connections L to detach the three toe-pliers simultaneously when hand-lever Ms is raised. All of these detaching devices travel with the pliers in their vertical adjustments.

End-lasting devices-The upper having been stretched and drawn up properly over thelast by the devices already described, the lasting devices or clamps begin their operation. I will now describe my improvements in these parts of the machine and in the means whereby they are supported and actuated. N N represent the heel and toelasting clamp stands provided at their bases with stands are provided with horizontal longitudinal clamp-bearings n2 n2, adapted to be compressed by hand-screws 'n2 upon slide-bearing sleeves N2 N3, which latter may thus be longitudinally adjusted and securely held. N4

N4 indicate slide-shafts iitting and freely movable endwise within the said sleeves and having near their inner ends vertical mortises n4. At their extreme inner ends the slides are provided with curved clamp-guides m5, which are compressible by hand-screws a6 upon correspondingly-shaped curved slides N5. The latter are provided with inwardly-extending perforated ears m7, between which are mounted the heel and toe lasting jaws N6 N7, hinged on pins ng, which pass through the perforations of the ears p7 and through bearings in the jaws. The slides N5 are ciroularly adj ustable in vertical longitudinal planes in the clamp-guides a5 to adapt the end jaws to the forward and rearward slants of the bottom of the last. The outwardly-extending arms n of the end-lastin g jaws are provided with balls a9, which are connected with stationary balls n10,rigidlysecured to the sleeves N2 N 3. Links O, provided with suitable sockets for said balls, connect the arms of the jaws with parts of the machine which are thus stationary. When, therefore, the jaws are by slides N4 bodily moved inward, they are caused to simultaneously close by reason of their arms being held back by the said links O. These links, Figs. 86 to 92, each comprise a central shank O, provided with a nut-shaped parto, by which the shank may be turned by a suitable wrench. The ends of the shank are provided with right and left screw-threads o 02, with flanges o3 at the base of the threads, and with hollows o4 on the extreme ends shaped to fit the balls rrilor w40. O2 O3 indicate caps which are respectively screwthreaded to iit the threads o o2 of the shank, and provided with hemispherical sockets o5, which lit said balls. At o6 the caps are cut away or open to accommodate the arm n of the ball nl and the stem 1112, which carries the ball n10, and is secured in the slide-bearing sleeve N2, or, in the case of sleeve N3, in a depending bracket w13 thereof. These parts are so fitted that when the shank O has been turned until the ilanges o3 bear against the edges of caps O2-O3 the balls will play freely in their sockets. The ends of the shank and the openings o6 are beveled, as indicated, to give sufficient range of movement to the arms n', and to the links relative to the stems 71,42. Flanges o3 are undercut toinclose the edges of caps O2 O3 and prevent them from spreading open. P Pare the end levers which actuate the slides N4 and give to the end-lasting jaws the movements already described. Said levers are mounted and os- IOO IIO

p3, with which it is also connected by a ccntral pin p4, and said side pieces tit neatly and are adapted to move vertically in the inortisc n4 of the slide N4, thus forming a combined slide-hinge joint P. The eyes p2 below the table have similar joints P2, with the inortises q, of two horizontal longitudinal slide-shafts Q, mounted in bushings q', which are fitted in the bearing-plates d d2. The fulcrum-pins p are cairied by the verticallyforked inner ends P3 of longitudinally-adjustable end fulcruin-shafts P4, mounted in bearings N8,formed in the stands N N. In the outer portions of the stands are screwed internally-threaded bushings N9, within which fit correspondingly-threaded screw-sleeves P5, provided with external milled heads or handles p5. Within these sleeves neatly fit the outwardly-extending stems p6 of the shaf ts P4,

which are held from inwardv movement from' the sleeves by nuts P6, engaging the threaded ends of said stems and abutting against the outer faces of the sleeves P5. It will thus be seen that the end-lever fulcrums may be readily adjusted to suit the length of last by turning the sleeves P5, the shafts P4 being prevented from turning by the engagement of the end levers with their forked ends P3. During this adjustment screws n3are loosened.

Side-lasting devices cmd actuating mechanism-The side-lasting-clamp levers are shown at R. They are mounted upon fulcrum-pins o', carried by slide-shafts R', the latter being mounted in the bearings e201? the side stands E and adjustable by means of sleeves R2, engaging the shafts R and screwing in the bushings E', in a manner substantially similar to that already described in connection with the end levers. At their lower ends, below the table, side levers R are provided with slide-hinge joints R3, by means of which they connect with slide-nuts S S', moving transversely, with their upwardly-extending ribs's fitting between the guides d5. `Said nutsare formed with lateral recesses s', in each of which fits neatly one of the vertically-movable slide-joint-socket pieces 0". The lower ends of the side levers are forked, Fig. 44, each lever having two eyes fr?, which accurately t the socket-pieces r on each side of the slide-nuts S S', Figs. 1 and 25, and are additionally hinged thereto by pins r3. Nuts S S are engaged by right and left threads S2 SS, formed on a transverse power-shaft S4, the outer ends of which are mounted in bushings s2 s3, itted into the extensions A of the table and clamped in place by nuts s4. Said shaft is further supported at the middle and held from endwise movement by being made in two parts vscrewed and pinned together, one of which has a journal S5, mounted in the bracket a, and a boss S6 and screw-threaded Stem S7, which tit in the other part of the shaft. The bushing or bearing s2 is provided with a set-screw sg, which bears against the end of shaft S, or against an interposed washer or packing, and is adapted to takeiip end play. The slide-nut S is formed with lateral ears s ou each side thereof which carry hinge-pins S10. The latter engage eyes in the ends of links Si, which extend horizontally inward by the sides of shaft S4 to a point where, by pins s, they are hinged to the longitudinal arms of angle-levers S. At their angles these levers are fulcrumed bybolts S13 to the lower ends of bosses a, and their lateral arms extend inward to points inline with the slide-shafts Q, to which they are connected by links Q. It will therefore be seen that when the power-shaft S4 is rotated in the proper direction to the right in Fig. 25 the parts connected directly and indirectly therewith will 4be moved in the directions indicated by the arrows in said figure, the lower ,ends ot' both the side and end levers will be forced outward, and their upper ends, carrying the lasting-clamps, will swing inward toward the last and force the clamps against the upper, which at such time will be held by the pliers.

In Figs. 32, 33, and et, l have shown a modified construction of the slide-shafts Q and their connections, by which the point of engagement between them and the end levers is rendered adjustable longitudinally for entreme lengths of lasts. According to this construction the shafts Q are screw-threaded at q2 and engaged by screw-sleeves Q2, having milled edges Q3 and peripheral grooves Q4, Fig. In these grooves and resting tangentially upon the central portion of the sleeves at each side thereof fit the slide-joint pieces g5, Fig. 2, in the sockets of whichare held the eyes p2 of the forked ends P" of the end levers P, which are thus modified in form, Fig. 445. Near their upper ends the side levers R are provided each with a transverse flange r4,'above which the lever is continued in the form of a short screw-threaded stem T5, upon which is screwed a hollow socket-piece T. The latter is then for greater security fastened by a transverse pin t, Figs. 36 and 37, which also holds in position an external sleeve T', inclosing the lower cylindrical extension t of the said socket-piece. On the inner side the said extension and sleeve are perforated, as shown at t2, and at t3 t3, just above sleeve T', the extension t' is perforated through both the inner and outer sides. In line with the perforations t3 is situated a screw stop-pin u, mounted and adjustable in the extension u' of the oscillatory holder U. also hollow. The length of the pin is equal to the external diameter of the eX- tension t. The upper part of the holder forms a hemispherical inner socket-piece il?, which fits accurately in a correspondinglyshaped portion ti of the outer piece T, and is secured in place and permitted to oscillate only in the transverse plane of the machine byhinge-bolts t5 t5, Fig. 4l, which pass through IOC IIO

and have bearings in the sides of the socket t4 and screw into the part u2. A spring U held at its upper end in a split tapered plug a3, driven int-o a tapered hole in the hollow cylindrical extension u and situated within said extension, bears at its lower free end against the inner end of a pin t, which is screwed or otherwise secured in the wall of the outer side of extension t and projecting inward through a perforation in the outer side of extension u into the interior of the latter. The tension of the spring U is such that it will always tend to force the lower end of the holder U inward and its upper end outward relative to the socket-piece T, thus elevating the inner ends or edges of the sidelasting clamps V, which are carried by said holder. In this position said lasting devices will pass inward over the edge of the last at a height just above the top surface of the inner sole. Having passed the edge of the latter, the clamps V are depressed t-ightl y against the upper, moving at the same time slightly inward, and the lasting operation proper willl be finished and the upper ready to be tacked or cemented in place. During this action of the lasting devices the head and pliers maybe lowered slightly to'yield a little ot' the upper to the lasting-clamps and prevent tearing of -the material. The said depression of the side clamps is effected by stop screws W WV, mounted and horizontally adjustable in eyes w w, and situated in line with the perforations t2,'so that when the side levers are near the limit of their inward movement the outer ends of said screws will enter the perforations and arrest the extensions u', Fig. 1. The eyes w are carried by a Y-frame WV', the lower portion of which is a cylindrical journal w', vertically mounted and swiveling in a bearing-sleeve W2. The latter has at its bottom a T-head w2, adapted to pass down through the enlargement 01,12 of the table-groove and when turned crosswise to fit the undercut portion als of the same. It is then clamped in place by a nut w3, which engages a thread on the sleeve and bears against a washer w4, which in turn rests upon the top surface of the table, Fig. 1.

The holder U is provided with an internal hemispherical socket, which is completed and adapted to form one member of a ball-andsocket joint by a screw-plug U2, suitably concaved on its inner face and screwed into the upper end of the holder. Within the socket thus formed are situated two hemispherical clamping-pieces U2, between which and half in each is formed a cylindrical clamp-bearing uf", adapted to receive the shank V of the side clamp. The latter may be formed with its shank substantially vertical or in line with the side lever, Fig. 1, or with the shank at right angles to the lever, Fig. 59, and therefore the clampingpieces U3 will be correspondingly arranged, with their bearing u in line with the shank V. The clampingpieces are forced together and upon the shank V by means of a set-screw V4, which passes through and engages the holder or a portion thereof either horizontally, as in Fig. 1, or vertically, as in Fig. 59. In the former case the outer socket-piece T is provided with an aperture tl on its outer side to accommodate the set-screw. In the latter case the part of the holder engaged directly by the threads of the screw V4 will be the plug U2. It' desired, a bearing-piece u, Fig. 59, may be interposed between the screw V4and the clamping-piece U2 to give a wider bearing on and obviate any tendency to turn the latter.

U5, Fig. 1, is a screw engaging the holdersocket and projecting at its inner end into a recess a7 larger than the screw, which is formed in one of the clamping-pieces U2. This screw prevents the clam p-bearing a5 from being twisted away from the opening in the holder through which the shank V eniers. In Fig. 59 a similar office is performed by the upper end us'of plug u2. In this latter construction, Fig. 60, screws a9 are provided engaging the plug and inner socket-piece to prevent any chance of the unscrewing of the former while working the clamp-screw V4.

It will be seen that by the parts describedthe side-lasting clamps are so mounted as to be universally adjustable in any direction within limits ample for the purpose, and can therefore befixed in the position necessary for their proper operation relative to the last. While so adjusting the clamps they are brought forward against the last and should be rigid upon their levers. The stop-pin u, already referred to, is provided for this purpose, and is designed to act in conjunction with a sleeve T2, which encircles the exten'- sion t below a flange t8 and rests on the upper end of the fixed sleeve T. While thus held in position vertically opposite to the pin u the sleeve T3 may be readily rotated to bring its solid portion against the ends of said pin, or to bring in line with the same the openings tu. In the latter ease the holder U may oscillate freely. In the former it will be rigidly held. The upper edge of the sleeve T3 is'cut away for about a quarter of a circle, forming a recess at t9, the ends of which are engaged by a pin 1510, driven into the extension t', Fig. 40.

In order that the blades V2 of the side-lasting clamps may lie substantiallyhorizontal when the side levers are at the inner limit of their throw, Figs. 1 and 59,I form said blade at an obtuse angle to the shank V.

The blade of thin elastic steel or other suitable material is stamped or otherwise formed along its operative edge, Figs. 59, 61, 62, and 63, so as to conform to acertain size and shape of last, (or to the average of several lasts,) and is preferably partially divided to form separate spring-lingers fu. More elasticity maybe given to the latter by perforat-ing the blade V2 at o at the bases of the fingers. The nec- IOO ITO

essary strength is given to the blade as a whole by a vertical rib c2, formed at its rear edge and with the shank V.

The tapering of the space between the hanger-legs and ot the plier-pieces already mentioned need only occur in the toe-pliers,

where it is especially necessary to prevent interference between the different pliers as they are attached to the upper around a narrow or' pointed toe.

The detaching connections L or L4 may be secured to either of the elbow-joint pieces instead of to the pin lao-as, for instance,to the piece K2--by means of pertorations or eyes 7640, Fig. 1.

The shaft S4 may be operated by the handcrank shown or by fast and loose pulleys and steam or other power.

If desired, the table-legs may be dispensed with and the table-top bolted upon a bench or other suitable support.

In adapting the machine to operate in conjunction with the particular shape and size of last which is to be employed the operation is as follows, (referring especially to Fig. 1:) The lasting devices being in the Vposition in which they were left at the close of the previous lasting operation-that is to say, away from the last-the new last, having the insole and upper in place thereon, is placed upon the heel and toe stands. By means of the Various adjusting devices with which the latter are provided the last is then brought into line with the end clamps and raised or lowered as may be necessary to the proper height relative thereto. During these adjustments ot the last the lasting devices may, by means of the power mechanism, be caused to approach the last, in order that the proper position of the same may be accurately determined. The clamp-screws a3 having been slackened, the power-shaft S4 is turned to cause the nuts S S to abut against the ends of sleeves s3 s2, and at the same time the end clamps to abut against the ends of the last, thisresult being aided (in case of variation in the lengths of the previous and present lasts) by turning the end fulcrum-screws P5 and, in extreme cases, adjusting the end stands N N in the groove a8. The sleeves N 2 N3 are then adjusted longitudinally in their bearings n2 to such points that the end-lasting jaws N9 N7 will assume their closed position, whereupon the bearings n2 will be caused to rigidly secure the sleeve N2 N3 by means of said screws n3. A pair of side-lasting clamps having been selected which will correspond in the contour of their operative edges with the last already chosen, they are placed in position on the side levers ,with their shanks inserted in the bearings a5.

The sleeve T3 having been turned so as to engage both ends ot the stop-pin a, Fig. 39, so as to prevent the oscillation of the holder U, the side-lastingclamps are (by the power mechanism) brought approximately into contact with the upper, and said clamps are then adjusted accurately to the last by twisting their secured by the screws V4.

shanks in the bearings a5 and by turning the clamping-pieces U5 inthe socket which contains them. The side clamps are then rmly Bylthe combined operation of the power mechanism and of the side fulcrum-screws R2 the parts are brought into such relative positions that when the'nuts S S are in their outermost position abutted against the bushings s2 s3 the operative edges of the side-lasting clamps are in their filial innermost position, with the upper suitably stretched and lasted. The lasting-clamp being now retracted by the power mechanism and the sleeves Tgbeing so turned as to permit the oscillation of the holder and the screws W having been so adj usted that theywill at the proper time (at or near the end otv the inner movement of the side clamp) arrest the lower ends of the holders U, the machine will be ready for any desired number of successive lasting operations in conjunction with the last for which themachine has been adjusted, as above described.

It will be noted that the inner ends of the bushings or bearings s2 s3 serve as positive stops, which limit the inward movements of the lasting devices beyond a certain point, thus preventing the possibility of injury to the upper or to the last.

While in this application I desire to be understood as making a generic claim to the actuating mechanism comprising the screwshaft S4, whether that shaft be arranged longitudinally or transversely relative to the last and head, I do not herein claim specifically that modiiication in which the said screwshaft is arranged longitudinally.
