Application filed May 11, 1918. Serial No. 98,781.

To allwliomzt may concern:

Be'it known that I, ERASTUS E. WINKLEY,

a citizen of the United States, residing at L nn, in the county of Essex and State of assachusetts, have invented certain new and useful Improvements in Shank-Edge Trimmers; and I do hereby declare the followin to be a full, clear, and exact dc.- scri tlon of the invention, such as will ena 1e others skilled in the art to' which it ap ertains to make and use the same.

his invention relates to a machine for operating upon shoes, and it has special reference to machines for finishing sole edges, and particularly for trimming, or partially trimming, the edges of they shank of the outby a special machine for that purpose. This heel-jointing is necessary both because theordinary rotary trimming-cutter cannot work up into the angle between the sole and the breast of the heel, and because the shank must be trimmed at its rear e'xtremity, in order to produce a neat finish, with reference to the finished surfaces of the heel and not with reference to the hottom of the crease.

The present inventor has devised a method of making shoes, set forth and claimed in a co-pending divisional application, Serial No. 371,917, filed April 7 1920, in accordance with which the shank-edges are trimmed before the application of the heel, and in which the heel is also finished before its application, and one object of the present invention is to produce a machine adapted particularly for performing a preliminary shank-edge trimmlng operation in carrying out the method above referred to.

For this purpose the machine is provided with novel means for gaging the depth of the cuts produced in the trimming operation so that this depth, instead of belng determined either by the skill of the operator or characteristics thereof.

by reference to the crease of the shoe, shall be so determmed that the trimmed shankedges shall exactly co incide,-at the rear extrem1t ,-w1th the finished surfaces of the heel w en the latter is subsequently applied. Smce the location of the heel is determined, 1n the methodabove referred to, with reference to the orlginal outline of the sole,and preferably by a tongue or narrow extenslon at the rear extremity of the shank, the machine of the present invention is so con structed as to the rear extremlty of the shank, in accordance with the original outline of the sole,

and preferably by coo eration of its gag-.

ing mechanism with t ferred to.

In another and broader aspect, ,an object of the present invention is to provide a shoe machine which shall perform its intended operation or function upon each shoe. pree tongue above resented thereto in accordance with the particular characteristics of the individual shoe being operated upon. To this end, a feature of the invention resides in the provision of operating means which is prescribed in its action by movable guiding means that is provided with means constructed and arranged to enga e each shoe operated upon for adjusting t e position of the iding,

means in accordance with the in ividual Other objects of the invention, and the various features of construction bywhich these objects are attained, will be set forth hereinafter, in connection with the description of the illustratedembodiment of the invention.

In the accompanying drawings Figure 1 is a side-elevation of a machine embodying the present invention; Fig. 2 is a planview of a portion of a shoe, showing the character 0 the Work performed by the machine; Fig. 3 is a plan-view of the machine, on a larger scale than Fig. 1; Fig. 4 is a front-elevation of the upper portion of the machine, with a part of the crossbar broken away; Fig. 5 is a frontselevation of the lower portion of the machine, on a smaller scale than Fig. 4; Fig. 6 is a verticalsection on the line 66 in Fig. 3, but on a larger scale than the latter figure; Fig. 7 is a section on the line 7-7 in Fig. 1, looking upwardly and on a-larger scale than ge. the trimming-cuts, at

the latter figure; Fig. 8 is a horizontal section on the line 8-8 in Fig. 5; and Fig. 9 is a vertical section on the line 99 in Fig. l.

The construction and operation of the machine may be best understood in view of the character of the "work which it performs. Fig. 2 shows a portion of a lasted shoe, of which the outer sole 11 has been stitched in place and the heel 13 has also been aflixed. In this shoe, as hereinbefore described, the sole is provided with a rearward extension or tongue 12 from the rear extremity of the shank-portion of the sole, this tongue being narrower than the shank-portion. The heel is finished before its application, and it is provided with a recess which receives the tongue 12, and whereby the heel is located accurately with respect to the shank of the sole. The edges of the shank-portion have been trimmed previous to the application of the heel, as shown by shading in Fig. 2, the trimming operation involving the removal of the surplus material which is shown by the dotted lines 14 constituting a part of the original outline of the sole.

The principal function of the present machine is to perform the preliminary trimming operation in such a manner that the rear extremities. of the trimming-cuts shall leave the shank-portion of the shoe, at its rear extremity, with an outline having an exact relation to the width and location of the tongue 12, so that when the previously finished heel 13 is placed on the sole the finished lateral surfaces of the heel shall be exactly contiguous with the trimmed edges of the shank.

A subsidiary function of the machine is to facilitate the smooth blending of the short trimming-cuts performed by the machine. with the trimming-cuts which may be subsequently performed in the usual manner, in trimming the rest of the shank. This latter trimming operation is guided with reference, not to the original outline of the sole, but rather to the position of other parts of .the shoe, particularly the bottom of the crease between the welt and the upper.

The operative instrumentalities of the present machine comprise, as shown particularly in' Fig. 7, two rotary trimming-cutters or tools 15, which operate progressively along the sole-edge toward the rear extremities of the shank. The position of the shoe during the trimming operation is accurately and automatically determined with reference to four points of the shoe. Two of these points are the angles between the tongue 12 and the rear extremity of the shank-portion. For this purpose the machine is provided with two gages 16, which may be described as tongue-gages. The other two points of location are at the bottom of the crease, slightly in advance of the points at which the trimming-cuts are commenced, and these gagingpoint are located by means of two creasegages 17. having acute ends adapted to enter the creases to the bottoms thereof. In Fig. 7 the sole 11 only of the shoe is shown. for the purpose of illustration, the other parts of the shoe, which are above the sectioirplanc, being omitted, and the bottoms of the crease are indicated by broken lines 18.

\Vhen the shoe has been located in the machine by the four gages just described, the paths of operation of the trimming-cutters are determined with reference to the positions of the gages. For this purpose the cutters are rotatably mounted upon laterally-movable slides 19 (Fig. 7), which are provided with guide-rollers 21. Each of these rollers moves along the outer cam-like surface of a cutter-guide or templet in the form of a bar 22. The rear end of each guide is attached, by a pivot 23, to a bracket 24 extending forwardly from a slide 25 upon which one of the tongue-gages 16 is also rigidly mounted. The slides 25 move laterally in a gu deway 20 on the frame of the machine. Since the pivots 23 are laterally in line with the rear extremity of the shank when the tongue-gages are in engagement with the angle between the tongue and the shank, as shown in Fig. 7, the depth of the cuts produced by the trimming-tools is exactly determined, at the rear extremity of the shank, in accordance with the width of the tongue. Since, also, the sole with the tongue is produced by a dieing-out operation which positively determines the relative widths and positions of the tongue and the shank, it follows that the trimming-cuts have, at the rear extremity of the shank, a definite relation to the original outline of the shank at this point.

It will be observed, also, that the cutter guides or templets 22 are of such length as to extend beyond the heel end of the shankedge, of the short outsole illustrated in Fig. 7. and that their curvature is such that the rolls 21, in traveling over them, carry the cutters 15 in a path in extension of the curvature of the shank-edge as they leave engagement with the sole. This provides for an exact width of sole at the heel end of the shank equal to the width of the breast of the heel, and a sharp corner on the short outsole to abut the heel breast.

The forward ends of the cutter-guides 22 are connected, by pivots 26, with two slides 27, and the crease-gages 17 are also mounted on these slides. For this purpose the creasegages are provided with shanks 54 which are fastened, by set-screws, in sleeves 55 integral with the slides. The slides move laterally in slide-guides 56 on the frame of the machine.

Since the position of the forward ends of" the cutter-guides is determined by reference to the creases of the shoe, it follows that the trimming-cuts, at their forward extremities, are regulated as to depth and pos1t1on by reference rather to the position of the crease or edge ofthe last within the shoe, than to the original outline of the shoe-sole, and accordingly the trimming-cuts produced by the present machine may be smoothly blended, at their forward extremities, with trimming-cuts produced in the usual manner and gaged by the crease of the shoe.

Prior tothe introduction of the shoe between the gages it is necessary to draw these gages apart, and for this purpose mechanism 1s employed which is operated by a treadle. To each of the slides 25 a link 28 is at tached, by a pivot-screw 29, and the outer ends of the links are pivoted to arms 31 constituting parts of two bellorank levers which swing about pivot-rods 32 fixed vertically on the frame of the machine. The second arms 33 of the respective bell-crank levers are connected, by short links 34 (Figs. 6 and 9), with the upper and lower ends of a head 35 which slides horizontally on a rod 36. This rod is fixed in brackets 37 on the frame of the machine. A tensionspring 38 (Figs. 7 and 9), connected at its ends wi+h the two leverarms 31, tends to draw them together so as to move the tongue-gages 16 toward each other,.and the arrangement of the levers and the head 35 is such as to cause the movements of the levers and of the tongue-gages to be always e ual and in opposite dlrections, so that w en the parts are released from the operation of the treadle 52 (Fig. 1) the spring 38 causes the gages to centralize the tongue as well as to press against the sides of it. At the same time the operator pushes the shoe rearwardly, so as to cause the rear extremity of the shank to engage the tongue-gages.

The head 35 is connected, by a pivot-pin 39, with a link 41 (Fig. 7) which is pivoted to the upper end of a lever 42. This lever is mounted to swing freely on a rod 43 fixed in the frame of the machine. The lever 42 is provided with a lug 44, in position t be engaged by an adjustablescrew 45 (Fig. 1) carried bya yoke-shaped lever 46 which also turns upon the rod 43. The lever 46 has an arm 47 which is connected, by a rod 48, with a lever-arm 49. The arm 49 is integral with a sleeve 50 (Fig. 5), whichturns on a rod 51 fixed at the bottom of the frame of the machine. A treadlelever 52 is also integral with the sleeve 50. A spring 53, attached to the treadle-lever, holds it normally in raised position. When the treadle is depressed the lever 46 is swung in a direction to cause the screw 45 to swing the lever 42 forwardly, thus slid ing the head 35 forwardly on the rod 36 and causing the tongue-gages to be moved apart. When the parts are n their normal .anism very simi position the screw 45 is out of engagement with thelug 44, so that the tongue-gages are free to assume their proper operative positions under the influence of the spring 38. i

The crease-gages are controlled by mechar to,

(Fig. 7) are'connected, by pivot-pins 58, with arms 57 constituting parts of two bell-crank levers which turn on the rods 32. The other arms 59 of the levers are connected, by links 61, with a head 62 (Fig. 9) which slides on a rod 63 mounted in the brackets 37; This head is connected, by a link 64 (Fig. 7), with alever 65 arranged alongside the lever 42. The lever 65 cooperateswith a second screw 66, carried by the lever 46, so that when the treadle 52 is '70 and in part common w1th, that just described. The slides 27.

depressed the. crease-gages are-moved apart in the same manner as the tongue-gages. The crease-gages are drawn toward each other by the operation of a tension-spring 67 (Figs. 7 and 9) which connects the leverarms 57.

The trimming-cutters, in addition to rotating, are moved inwardly and outwardly to engagethem with and disengage them from the work and to regulate the depth of the cuts produced, and they are also moved in a fore-and-aft direction to cause them to act progressively on the shank and then to return to their original positions. To cause the rotation of the cutters each cutter is mounted on a vertical shaft 68 (Figs. 4 and 8), which turns in upper and lower bearing-sleeve 70 and 80. These sleeves are connected by an integral yoke, as shown in dotted lines in Fig. 4, and each sleeve 70 is integral with the corresponding slide 19.

Between the bearing-sleeves each shaft carries a pulley which is connected, by a belt 78, with a drive-pulley 76. 1

It is necessary to maintain, duringv the fore-and-aft movements of the cutters, a constant distance between thecutter-shafts and the drive-pulley 76. Accordingly these parts are connected together bya single fore-and-aft slide. The frameof the machine is provided, at the top, with two longitudinal slide-guides 71 (Figs. 4 and 6), and the slides 19 move in a transverse guideway 69 which is connected with rearwardly extending slide-bars 72 which move in the slide-guides 71. The bars 72- are connected, at their rear ends, by a yoke 73 and a cross-bar 74, as shown particularly in Figs. 1 and 9. Cheeks 75, which rise from the sides of the slide, provide. bearings for the shaft of the drive-pulley 76, and also for the shaft of an idler-pulley 77 which is located in front of the nulley 76 so as to guide the quarter-turn belts 78. The drive-pulley is connected, by a vertical belt 79 (Fig. .1) with a pulley 81 mounted on the power-shaft 82 of the machine. This shaft is driven constantly by connection with any suitable source of power.

The movements of the trimming-cutters are performed automatically through a complete cycle, the commencement ot'the movements being determined by the operator. For this purpose, the slides which control the -movements of the cutters are actuated by a cam mechanism driven through a Horton or one-revolution clutch. The power-shaft 82 is connected, by mitergears 84 (Fig. with a vertical wormshaft 86 which is journaled in the frame of the machine. The worm-shaft carries a worm which meshes with a worm-wheel 88 (Fig. 8) rotatable about a cam-shaft 90 which is journaled in the frame.

The \\'oi'm-wlieel is connected with one member of. a Horton clutch 92, of which the other member is fixed to the shaft. The construction of this clutch is not particularly illustrated, as devices of the kind are well known, but it will be understood that the operation of the clutch is controlled, in the usual manner, by means of a stop-member 94 which is provided with a shoulder, as shown in dotted lines in Fig. 1, arranged to coiiperate with a lug on one end of a detentlever 96, which is pivoted on the frame of the machine. A spring 98 connected to the lever 96 tends to throw it upwardly so as to engage the shoulder and arrest the movement of the clutch at the completion of each rotation. To permit the clutch to be thrown into operation the detent-lever is connected, by a rod 100, with a treadle-lever 102, which is normally held in its upper position by connection with the same spring 98 by which the detent-lever is controlled. Each time the treadle 102 is depressed and released the cam-shaft 90 performs one complete rotation and then comes to rest.

The transverse movements of the slides 19, by which the trimming-cutters are brought into and out of engagement with the work. are controlled by a cam 104 (Figs. 5 and 8) on the cam-shaft 90. This cam engages a roller 106 on onearm 108 of a bell-crank lever which turns loosely on a rod 110 fixed on the frame of the machine. The other arm 112 of the bell-crank lever is connected, by a rod 114, with one arm 116 (Fig. 9) of a second hell-crank lever, which turns loosely on a rod 118 which is supported in brackets 119 on the frame of the machine. A second arm 120, integral with the arm 116. is connected, by a link 122, with an arm 124 depending from a sleeve 125. The sleeve turns loosely on a rod 126 which is supported in uprights 127. From the middle of the sleeve 125 an arm 128 projects forwardly, and is provided with a wide end which is adapted to engage simultaneously the ends of two arms 130 (Figs. 3 and 4) projecting from sleeves 132. These sleeves are fixed on rods 134 which are journaled, in parallel positions. in bearings 1.36 on the frame of the machine. From each sleeve 132 two arms 138 depend, and support a horizontal rod 140. Each of the rods 140 pass through a horizontal opening in the yoke which connects the upper and lower bearings and 80 in which one of the cutter-shafts G8 is supported, as shown particularly in Fig. 4. This arrangement is such that while the rods 140 do not interfere with fore-and-aft movements of the yokes. they cause the yokes, and thus the slides 19 and the trimming-cutters, to move transversely when the arms 138 are rocked. The inward movement of the arms 138 is caused by springs 142, which are coiled around the rods 134, as shown in Fig. 9. and are connected. at their opposite ends, with the bearings 136 and collars on the ends of the rods. The engagement of the cutters with the work is accordingly produced by the resilient action of the springs. The opposite or disengaging movement of the cutters is produced positively, by the action of the cam 104 and the intervening mechanism above described.

The fore-and-aft movements of the cutters. by which they are caused to traverse the sole-edge and also to return to their original positions, is produced by a cam 144 (Figs. 5 and 8) on the cam-shaft 90. This cam engages a roller 146 carried by one arm 148 of a bell-crank lever pivoted on the rod 110. and the other arm 150 of the lever is connected, by a rod- 152, with a bell-crank lever 154 (Fig. 7) which is mounted on the rod 118. The other arm 156 (Fig. 9)- of the latter bell-crank lever is connected, by a link 158, with a bearing-lug on the cross-bar 74 which forms a part of the fore-and-aft slide by which the slideuide 69 is supported. This slide is, therei ore, moved positively by the action of the cam 144, in proper timed cotiperation with the other parts of the mechanism.

To insure an exact registry of the trimming-cutters with the edges of the shank each cutter is provided with a smooth flange 160 (Figs. 7 and 9), which is adapted to enter the crease of the shoe and bear against the grain surface of the welt. This flange is not designed, however, to limit the movement of the trimming-cutter by engagement with the bottom of the crease, since this function is performed, in the present machine, by the guiding-mechanisms heretofore described.

A chute 162 (Figs. 1 and 9) is provided beneath the trimming-cutters to receive the material removed. The chute may be connected, in the usual manner, with an exhauster to carry away the dust.

The operation of the machine, asa whole, is as follows: In the normal position of the parts the trimming-cutters are in their fore-v most position and are widely separated from each other, and all parts of the machine are at rest, except the power-shaft 82 and the belt-connections by which the trimmingcutters are constantly rotated. The operator holds the lasted shoe, on which a short outsole has been laid, in inverted position and introduces it between the cutters so as to bring the tongue 12 of such an outsole into a position between the tongue-gages 16;

While so introducing the work the operator holds the treadle 52 in depressed position, so that the tongue-gages and the cross-gages are held widely apart. The operator then releases the treadle 52, allowing the gages to seat themselves against the work, and at the same time presses the shoe rearwardly to cause the tongue-gages to be engaged by the shoulders at the extremities of the shank of the sole, formed by the tongue 12. The operator then depresses and releases the treadle 102. This causes the clutch to im-- part one-rotation to the cam-shaft 90, and by the action of the cams, as above described, the trimming-cutters are caused, first, to approach and cut into the work to the depth determined by the guides or templets 22, then to move to and past the rear extremities of the shank, so as to trim these extremities to a contour determined by the gages, then to move away from each other and out of engagement with the work, and finally, to

return to their. original position and come to rest, the cycle of operations of the machine being thus completed. The operator then again depresses the treadle 52, removes thetrimmed shoe, and substitutes another.

The invention has been illustrated and described as embodied in a machine arranged to trim only therear portions of the shankedges, as this is the function for which the machine is particularly designed, but it Will be apparent, that the invention is not limited to embodiment in a machine arranged to opcrate in this restrictedmanner, I
