67 Claims.
-This invention relates to machines for use in the manufacture of shoes and in some aspects more particularly to machines for shaping uppers over lasts. The invention is herein shown as embodied in a machine for lasting the sides of shoes between their toe and heel-end portions, and adapted more particularly for operation upon shoes in which the upper in the lasting operation is secured to the insole by adhesion, but j() it will be recognized that in many of its novel features the invention is not limited to the manufacture of that type of shoe o-r limited in respect to the portion of the shoe upon which the operation is performed.
Important features of the invention are to be recognized in a novel combination of means for conforming an upper tightly to the contour of its last and for pulling its marginal portion inwardly over an insole on the last without any substantial 0 pressure of the upper against the insole and then pressing its marginal portion upon the insole while under pulling strain and wiping it inwardly over the insole. Thus the danger of any slackening of the upper on its last after the upper-pullg5 ing operation is avoided and in the manufacture of a shoe the margin of the upper of which is secured to the insole by adhesion substantial insurance is afforded that the insole will not be wrinkled or otherwise displaced in the overwiping 3() operation and that the margin of the upper will not be pressed into premature adherence to the insole. In one important aspect the invention provides for thus operating upon the upper along the shank and forepart of the shoe. As herein shown the machine is provided with upper-pulling means comprising grippers arranged to operate at the ball and shank portions of the shoe and movable inwardly over the shoe bottom to tighten the upper over its last and to draw its marginal l portion inwardly over the insole, overlaying members or wipers movable with said grippers and arranged to extend along the opposite sides of the shoe between its toe and heel-end portions, and mechanism for effecting relative movement 5 of the wipers and the shoe heightwise of the shoe to press the margin of the upper upon the insole after the margin cf the upper has been drawn inwardly over the insole and while the upper is held under strain by the grippers, this mechanism io` being arranged thereafter in response to resistance of the shoe to the pressure applied to impart to the wipers movements farther inwardly over the insole invwiping engagement with the upper while applying'progressively increasing pressure 35 to the upper heightwise of the last to force it into rm adherence to the insole. In accordance with a further feature the wipers are preferably heated, thus increasing the eectiveness of their action on the margin of the upper to smooth it free from wrinkles and to secure firm adhesion of the upper to the insole through hastening of the setting of the cement.
In the illustrated machine the shoe is supported yieldingly bottom downward with its bottom face located initially a predetermined distance above the upper-engaging faces of the wipers. A pair of abutments are provided for engaging the top of the heel end and the top of the forepart of the shoe and its last, to support the shoe against pressure applied on its bottom face, and means is provided, herein shown as a slide, for moving the shoe-supporting means toward the abutments to carry the shoe into engagement with the abutments and then to eifect a depression of the shoesupporting means relatively to the slide. The wipers are supported on the slide and are connected to supporting brackets by parallel links which are arranged to. impart to the wipers their inward movements without varying their angular relation to the shoe bottom, spring means being provided for opposing the inward movements of the wipers and for thereafter moving them outwardly. In the construction shown, the grippers comprise movable jaws carried by the wipers and, arranged to cooperate therewith to grip and pull the upper. The movable gripper jaws are located opposite each other along the shank portion of the shoe and at the opposite sides of the ball of the shoe, and in order that the gripper jaws may be moved relatively to the wipers to grip the upper before the wipers begin their inward movements, there is provided, in accordance with a further feature of the invention, mechanism operative in response to movement of the wiper support heightwise of the shoe to impart to the gripper jaws movements both heightwise and laterally of the shoe relatively to the wipers to clamp the opposite side portions of the margin of the upper against the wipers, this mechanism being operative thereafter to impart to the gripper jaws movements relatively to the wipers to release the upper in time relation to the inward movements of the wipers.
In order to determine the relation between the wipers and the shoe during the early part of the movement of the wipers and grippers inwardly over the insole, there is provided, in accordance with another feature of the invention, novel means for positioning the wipers heightwise of the shoe relatively'to the bottom of the shoe.
This means, as herein shown, comprises gaging devices which as the wipers are moved heightwise of the shoe engage the wipers and thus cause the parallel links to impart to the wipers their inward movements against the resistance of said spring means, the movements of the wipers toward the shoe being thus limited by the gaging devices which are also adjustable heightwise of the shoe to determine the distance between the wipers and the bottom face of the insole. In order that the spring means will be effective to impart to the wipers movements heightwise of the shoe to press the margin of the upper upon the insole, the machine is also provided with means for releasing the wipers from the gaging devices at a predetermined time in the inward movements of the wipers and grippers. As illustrated, this means comprises a pair of rods carried by the above-mentioned slide and arranged to impart to the gaging devices in time relation to the inward movements of the grippers and wipers movements heightwise of the shoe to release the wipers to the action of the spring means. As the slide continues to move upwardly, the wipers are moved farther inwardly over the insole in wiping engagement with the upper by the parallel links against the increasing resistance of the spring means. In accordance with another feature, there is provided means for preventing outward return movement of the wipers, in the movement of the slide away from the abutments, until after the shoe-supporting means has been returned relatively to the slide to its initial position, the shoe being thus support-ed above the path of the outwardly moving wipers so as to avoid any possibility of displacement of the margin of the upper by outward drag of the wipers thereon.
The above and other features of the invention, including various novel details of construction and combinations of parts, will now be more particularly set forth by reference to the accompanying drawings and pointed out in the claims.

The invention is illustrated as applied to a machine organization which is in many respects similar to that illustrated in Letters Patent of the United States No. 1,549,243, granted on August 11, 1925, on an application led in the name of E. E. Winkley with portions of the machine constructed as disclosed in Letters Patent of the United States No. 1,951,373, granted March 20, 1934, upon an application filed in my name, although it is to be understood that the invention is not limited to organizations of that particular character. Machines of the type illustrated in said Letters Patent are twin machines comprising two sets of mechanisms whereby one shoe is subjected to pressure simultaneously with the release from pressure of another shoe previously operated upon. Only one of the two sets of mechanisms is herein illustrated or need be referred to for an understanding of the present invention. As more fully illustrated in the above-mentioned Letters Patent No. 1,549,243 the machine is provided with a pair of vertical rods 20 (Figs. 1 and 2) which support adj ustably near their upper ends a cross-head 22. To this cross-head there are adjustably secured a toe post 24 and a heel post 26 which serve to support the shoe against upwardly directed pressure applied on its bottom face. The toe post 24 has a rubber-covered roll 28 thereon for engaging the shoe or last on the top of the forepart and the heel post is provided with a plate 30 arranged to engage the top face of the heel-end portion of the last, the plate 3D being mounted on a block 32 pivotally connected at 34 to the heel post and arranged to be swung about its pivot by an adjustable screw 36 against the action of a ilat spring 38 to adjust the plate 30 so that it will bear evenly on the top face of the last, as more fully disclosed in my copending application referred to above.
Mounted on the rods 20 is a slide 40 to which upward and downward movements are imparted through a link 42 connected at 44 to the slide and operated by mechanism not herein shown in detail since it is fully disclosed in the Letters Patent No. 1,549,243 above mentioned. The slide 40 supports a box 46 provided with a pair of trunnions one of which is indicated at 48 in Fig. 1
mounted in bearings on the slide so that the box may tip about an axis extending laterally of the shoe, the box being held normally in a predetermined position, determined by a spring-pressed plunger 50 carried by the box and engaging the slide, by a spring 52 connecting the slide and the box.
Vertically movable in the box 46 is a casting 54 supported by four springs 55 which are yieldable in response to resistance of the shoe to the pressure applied. Mounted in guideways on the casting 54 for movements in directions widthwise of the shoe is a slide 58 which is adjustable along its guideway by a screw 6I] held against lengthwise movement by a lug 62 fast on the casting. Mounted in guideways on the slide 58 for movements in directions lengthwise of the shoe is a slide 64 which is adjustable along the guideways by a screw 66 held against lengthwise movement relatively to the slide 64 by a plate 68 fast on the slide 64, the screw being threaded in a lug 10 on the slide 58 and having a hand wheel 'I2 thereon for turning it. The slide 64 serves as a support for four brackets two of which are located opposite each other near the toe end of the shoe and the other two of which are located opposite each other near the heel end of the shoe. The brackets 14 near the toe end of the shoe are mounted in guideways on the slide 64 for movements laterally of the shoe and are adjustable toward or from each other by a shaft- 16 having right and left-hand threads thereon engaging lugs on the brackets and a hand-wheel 'i8 secured to its outer end for turning it, the shaft 16 being held against lengthwise movement relatively to the slide 64 by spaced projections on the slide engaging shoulders 82 on the shaft. The brackets 84 (Fig. 6) at the heel end of the shoe are pivotally connected to the slide 64 by shouldered studs 86. The brackets 14,
84 have connected thereto respectively by par-` allel links 88, 99 angularly shaped holders 92, 94 and each pair of holders 92, 94 serve to support one of a pair of ironing members or wipers 96, 99. The wipers 96, 98 extend along the opposite sides of the shoe (Fig. 1), and are shaped both heightwise and widthwise of the shoe'to conform substantially tol the curvatures of the opposite edges of the shoe bottom. The wipers 96, 98 are positioned on the holders 94 by dowel pins |99 which extend upwardly into recesses formed in the wipers, and on the holders 92 by pins |92 extending upwardly into lengthwise slots |94 formed in the wipers, the wipers being provided also with convex projections |96 (Fig. 7), ar-
1 ranged to engage complementally shaped recesses |98 formed in the holders 92. It will be seen that rotation of the hand wheel 18 moves the brackets 14 toward or from each other and that this movement of the brackets 14 through the wipers 96, 98 causes the brackets 84 to swing about their pivotal connections to the slide 64. 'Ihe portions of the wipers near the toe end of the shoe are thus moved greater distances toward or from each other than the portions of the wipers near the shank of the shoe. Since variations in widths of shoes of different sizes are greater at the forepart than at the shank of the shoe, the Wipers 96, 98 may accordingly be adjusted to take care of a number of shoes of differentsizes, although for wide variations in sizes, as well as for variations in styles, differently formed wipers will be substituted.
One of each pair of parallel links supporting the holders 92, 94, on the brackets 14, 84, namely, the link 88, has an extension I9 to the outer end of which is pivotally connected a rod H2. Mounted on each rod H2 is a bushing H4 which is held against a shoulder H6 on the rod by a compression spring H8 surrounding the rod and engaging at its lower end a washer |29 supported by a nut |22 threaded on the rod, Fig. 2. Surrounding the bushing I4 and bearing at its lower end against a flange |24 on the bushing and at its upper end against a flange |26 formed on a second bushing |28 slidably mounted on the rod H2, above the shoulder H6, is a compression spring |39 which is of less capacity than the spring H8. Each bracket 14, 84, has a laterally extending forked arm |32 which partially surrounds the bushing |28 and is provided with recesses |34 arranged to receive trunnions |36 on the bushing |28, the construction being such that the springs |39 maintain the holders 92, 94, initially in upraised positions (Fig. 2), in which their outer side faces are against the upwardly extending portions of the brackets 14, 84. It will be seen that when the parallel links 68, 99 are swung about their pivots, by means hereinafter described, to impart inward movements to the wipers 96, 98, the springs |39 are compressed until the bushings I4 engage the bushings |28, after which continued swinging of the links 88, 99 acts to compress the stronger springs H8.
In the illustrated machine the shoe is supported initially bottom downward by a member |38 which, as sho-wn in Figs. 1 and 3, engages the heel-seat portion of the shoe, and a member |49 arranged to engage the bottom face of the insole substantially midway between the opposite sides of the shoe just rearwardly of the toe end of the shoe as shown in Figs. l and 2. The member |38 is mounted for sliding movements in directions heightwise of the shoe in a guideway formed in an upwardly extending arm |42 of a standard |44 secured to the casting 54. The arm |42 is provided with a shoulder |46 and projecting from the shoulder is a pin |49 which acts to centralize a compression spring |59 with a recess |52 formed in the member |38. The spring |59 bears at its lower end against the shoulder |46 and at its upper end against the member |38 at the upper end of the recess |52. A projection |54 on the arm |42 is arranged to engage a stop |56 on the member |38 and to limit the upward movement of the member |38 under the action of the spring |59. The forepart supporting member |49 is slidably mounted for movements in directions heightwise of the shoe in a guideway formed in a standard |58 secured to the slide 64 (Figs. l and 2) and is upheld with a projection |69 on the member |49 engaging a stop |62 on the standard by a compression spring |64 which bears at its lower end against the slide 64 and at its upper end against the member |49 at the upper end of a recess |66 formed in the memf ber'. The stops |56, |62 are so located that when the parts are in the positions shown in Figs. 1 and 2 the shoe is supported by the members |39, |49 with its bottom face a predetermined distance above the upper-engaging faces of the wipers 96, 98. In the upward movement of the slide 49, the shoe and last are carried into engagement with the members 28 and 39 by the supporting members |38 and |49 after which as the slide continues its upward movement the springs |59 and |64 are compressed, thus effectingv a depression of the supporting members |38 and |49 relativelyv to the slide.
In order to hold the shoe on the supporting members |88, |49 and to determine the proper lateral position of the heel-end portion of the shoe, the illustrated machine is provided with gages |68, one of which is shown in Fig. l, located opposite each other at the heel end. The gages |69 are substantially the same as similar mechanism shown and described in my copending application Serial No. 481,919 mentioned above, each gage comprising an arm |19 (Fig. l), mounted on a block |12 for swinging movements laterally of the shoe and having a leather cover |14 thereon to contact with the shoe. The arms |19 are interconnected to swing in unison and are adjustable toward or from each other by a shaft |16 having right and left threads in engagement with blocks |89 that are swiveled on the outer ends of the respective arms, the shaft having a knurled head |82 thereon for turning it. The supporting block |12 is pivoted at |84 on the standard |44 to permit the arms |19 to be swung out of operative position to facilitate removal of the wipers 96, 98. .A spring |86 connected to one of the arms |19 and to the standard |44 holds the arms normally in operative position, the arrangement of the spring in relation to the axis |64 being such that it will also maintain the arms in inoperative position when they are swung to that position.
The machine is provided with means for maintaining the wipers 96, 96 in a heated condition. For this purpose there is mounted in a recess in each end of each wiper 96, 98, an electrical heating unit |98. From each heating unit |88 electrical conductors |99 lead to any convenient source of electrical energy for heating it.
When the operator places the shoe on the supporting members 98, |49, the shoe is held against lateral tipping movements on these supports by the gages |68 which act also properly to position the heel end of the shoe laterally of the wipers. It is contemplated that the complementally shaped wipers 96, 98, will afford a suiiiciently definite indication of the lengthwise position of the shoe and that the operator, by swinging the toe end of the shoe, will locate the forepart in proper lateral position on the support |40. As the slide 40 moves upwardly the shoe and last are carried by the supports |38, |40 into engagement with the members 28, 30, and substantially at the time of such engagement upward movement of the wipers 96, 98 is limited by means which is arranged to determine the distance between the bottom face of the insole and the wipers as they begin their inward movements. By reference to Figs. 3, 4 and 5, it will be seen that each wiper 96, 98 has secured to it a bracket |92 which is arranged to engage, as the slide 40 moves upwardly, an abutment piece or stop |94 secured to a gaging member |96 which is slidably mounted on the rod 20. The gaging member |96 is supported on the rod by an adjustable collar |98 which is secured to the rod by a set screw 200. A heavy compression spring 202 surrounding the rod 20 and bearing at its lower end against the member |96 and at its upper end against the cross-head 22 acts to hold the member against its supporting collar |98. The stops |94 act to limit upward movement of the wipers 96, 98 by engagement with the brackets |92 secured to the wipers so that, as the slide 40 continues to move upwardly, the parallel links 88, are swung about their pivotal connections to the brackets 14, 84, thereby imparting inward movements to the wipers. By adjusting the positions of the collars |98 on rods 20 the heightwise positions of the gaging members |96 may be varied to vary the time in the upward movement of the slide 40 when the wipers 96, 98 begin their inward movements, the members |96 being preferably so-adjusted that the beginning of the inward movement of the wipers takes place substantially at the time when the shoe and last are moved into engagement with the members 28, 30. It will be understood that the inward movement of the wipers occurs against the resistance of the light compression springs |30 until the bushings |4 engage the bushings |28, after which the comparatively heavy compression springs ||8 are compressed as more particularly hereinafter evplained. It will be seen also that as the wipers move toward each other they are guided in their inward movements by the stops |94 against which the brackets |92 are held by the springs |30, the compression springs 202 being of suiicient capacity to prevent upward movement of the gaging members |96 at this time. By reference to Fig. 3 it will be evident that the wipers at the beginning of their inward movements are located somewhat below the bottom face of the insole and that as they move inwardly they act to bend the margin of the upper inwardly over the bottom of the shoe without pressing it against the insole. This prevents danger of displacement of the insole and insures also against premature adherence of the upper to the insole. The heightwise positions of the wipers at the beginning of their inward movements relatively to the bottom face of the insole may be varied by vertical adjustment of the collars |98 on the rod 20.
In order that the margin of the upper will be pressed into rm adherence to the insole, the machine is provided with means for moving the stops |94 out of engagement with the brackets |92 at a predetermined time in the cycle, so as to render the stops ineffective thereafter to limit the upward movements of the wipers. For this purpose the slide 40 has secured to it blocks 206 provided with recesses into which extend the lower end portions of rods 208 which extend upwardly in parallel relation to the rods 20. The rods 208 are pinned to the blocks 206 and pass through apertures in the collars |98 and into recesses 2|0 formed in the gaging members |96. Each gaging member |96 carries an adjustable set screw 2|2 which acts to close the upper end of the recess 2| 0 and to serve as an adjustable stop, the construction being such that, as the rods 208 move upwardly with the slide 40, they engage the stops 2| 2 and impart upward movements to the gaging members |96, against the resistance of the springs 202, to release the wipers 96, 98. When the wipers are released by the gaging members they are carried farther upwardly to press the margin of the upper against the insole. When the pressure is thus applied to the shoe by the wipers the resistance of the shoe to continued upward movement of the wipers causes a further swinging movement to be imparted to the parallel links 80, 90, so that the wipers are forced farther inwardly toward each other with a wiping action on the margin of the upper. The screws 2 I2 are so adjusted that upward movements are imparted to the gaging members |96 substantially at the time when the bushings |4 engage the bushings |28 so that continued swinging movements of the parallel links 88, 90, occur against the increasing resistance of the springs ||8 which act through the Wipers to press the margin of the upper firmly into adhering relation to the insole.
The illustrated machine is further provided with means for conforming the shoe upper closely and tightly to the contour of the sides of the shank portion of the last and for also conforming it tightly to the contour of the forepart of the last at the rear of the toe portion before pressing its marginal portion into adhering relation to the insole along the forepart and shank portions of the shoe. As shown, this means comprises gripi pers for gripping the opposite side portions of the margin of the upper at the shank portion of the shoe and at the opposite sides of the forepart of the shoe, said grippers being movable with the wipers inwardly over the shoe bottom to tighten i the upper over the last and to draw its marginal portion inwardly over the insole. Pivotally connected at 2| 4 to each bracket |92 (Figs. 3, 4 and 5) are a plurality of levers 2|6, to which there are pivotally connected at 2|8 gripper jaws 220. The gripper jaws 220, herein illustrated as six in number, three at each side of the shoe, are spaced apart lengthwise of the shoe from the ball of the shoe rearwardly along its shank portion, the jaws at each side being directly opposite corresponding jaws at the other side. Each gripper jaw 220 has pivotally connected to its lower end a rod 222 which extends through an enlarged opening formed in a downwardly extending arm 224 of a bell crank lever 226 also pivoted at 2| 4 to the C bracket |92. Each lever 224 has a laterally extending arm 228 carrying a roll 230 arranged to engage the bottom face of a steel plate 232 secured to the gaging member |96. Surrounding each rod 222 is a compression spring 234 which bears at one G end against a shoulder 236 on the rod and at the other end against a washer 238 provided with a concave face for engaging a convex projection 240 on the inner side face of the arm 224. A nut and lock nut 242, threaded on the end of the rod, are 7 arranged to hold a washer 244 in engagement with the opposite side face of the arm 224 when the parts are in their idle positions (Fig. 2). When the machine is initially at rest the spring 234 is under no compression, the parts 2|6, 220 71 andV 226 accordingly tending to swing as a unit about the axis 2|4 in a direction to hold the roll 239 in engagement with the plate 232. As the slide 49, however, moves upward relatively to the gaging members |96, before the members |92 engage the members |94, the levers 2|6 and 226 are swung in a direction to impart heightwise movement to the gripper jaw 229 relatively to the wipers 96, 98, the spring 234 acting at this time substantially as a solid member. Each lever 2|6 has an adjustable stop, illustrated as a screw 246, which is arranged to engage the bottom face of the wiper to limit upward swinging movement of the lever. Preferably, the stops 246 are so adjusted that only sufficient upward swinging movement will be imparted to each lever 2|6`to carryY its associated gripper jaw 229 upwardly into position to move relatively to the wiper to clamp the marginal portion of the upper against the inner side face of the wiper without moving the gripper jaw above the upper-engaging face of the wiper. Thereafter, as the levers 226 continue to swing in the same directions the gripper jaws 229 are rst swung toward the wipers about their pivotal connections 2|8 to the levers 2|6 to press the marginal portion of the upper against the inner side faces of the wipers, after which lthe springs 234 are compressed to cause the gripper jaws to clamp the margin of the upper hard against the wipers, the construction being such that sumcient swinging movements are imparted to the levers 226 to accomplish this before the brackets |92 are moved into engagement with the stops |94. As the wipers 96, 98 thereafter are moved toward each other from the positions shown in Fig. 3 to the positions shown in Fig. 4 by the swinging of the parallel links 88, 99, the upper is drawn tightly over the forepart and shank portions of the last by the inwardly moving gripper jaws cooperating with the wipers, the rolls 230 moving inwardly in engagement with the plates` 232. It will be evident that as the wipers and grippers thus move inwardly to pull the upper, the springs 234 through which the grippers are operated to clamp the upper will permit the upper to slip between the grippers and the wipers.
` Substantially at the timewhen the wipers 96, 98 are moved upwardly to press the margin of the upper against the insole an abutment piece 248 (Figs. 1, 2 and 4) secured to the slide 64 is arranged to be engaged by downwardly extending arms 259 carried by the levers 2| 6 as these levers are carried inwardly with the wipers. As the wipers and grippers move inwardlyfrom the positions shown in Fig. 4 to the positions shown in Fig. 5 the levers 2|6 are swung by the member 248 about their pivots 2|4 in directions to move the gripper jaws 229 downwardly out of engagement with the margin of the upper. reference to Figs. 4 and 5 it will be seen that the downwardly extending arms 259 engage the abutment piece 248 substantially at the time when the rods 29B engage the adjustable screws 2|2 carried by the gaging members |96. As the gaging 4members |96 move upwardly the springs |39 act to force the wipers 94, 96 upwardly to press the margin of the upper against the insole. Since the levers 2 I6, 226 move upwardly with the wipers there is no lowering of the gripper jaws 229 to releasethe margin of the upper until it has been pressed into adhering relation to the insole and the wipers have begun their inward movements to wipe and press the margin of the upper inwardly over the insole in response to resistance of the shoe to the pressure applied. The upper is thus held under pulling strain by the wipers and gripper jaws until its marginal portion has been pressed into adherence to the insole after which the levers 2 i 6 are swung about their pivots by the abutment 248 to lower the gripper jaws. By reference to Figs. 3, 4 and 5 it will be seen that the inner side faces of the wipers 96, 98, against which the upper engaging faces of the gripper jaws are held by the springs 234, are inclined downwardly and outwardly so that as the gripper jaws are lowered from positions shown in Fig. 4 to the positions shown in Fig. 5 their upper -endsv are swung away from each other to prevent interference between them as the wipers move inwardly to wipe and press the margin of the upper for its entire width upon the insole.
In order to avoid any possibility of displacement of the marginal portion of the upper from its proper relation to the insole in the return of the wipers to their starting positions there is provided means for preventing movement of the wipers 96, 98 outwardly away from each other until after the supporting members |38 and |49 have been returned to their initial shoe-supporting positions by the springs |59 and |64. This means comprises a latch 252 mounted adjacent to each pair of opposite holders 92 and 94 and arranged to engage projections V254 on the two holders when the parts are in the positions that they assume at the end of the wiping operation and thus to prevent the holders from being returned to their starting positions by the parallel links 88, 99, and the springs H6, |39, until after the slide 49 and the parts supported thereby have been moved downwardly far enough to permit the springs |48, |64 to move the members |38. |49 upwardly to cause the projections |54, |69 on the members |38, |49 to engage the stops |56, |62 on the standards |44, |58. Each latch 252 is fast on a rockshaft 256 (Figs. 1 and 2) supported in bearings on the end of the slide 64. Each rockshaft 256 has secured to it an inwardly extending arm 258 and pivotally connected to the inner end of each arm is a rod 269 extending upward loosely through an opening in a laterally extending projection 262 formed on the gaging member |96. A nut 264 on the upper end of the rod is arranged to cooperate with the projection 262 to hold the latch 252 in an idle position when the slide 49 and the parts supported thereon are in their lowest positions. As the slide 49 moves upwardly the rods 269 move relatively to the projections 262 until a compression spring 266 surrounding each rod engages the projection 262 after which, as the slide 49 continues to move upwardly, the springs 266 are compressed to swing the latches 252 into positions to catch on the projections 254 as soon as the holders 92 and 94 are lowered far enough relatively to the brackets 74, 64 to carry these projections below the latches. In the upward movements of the slide 49 and the rods 269 a sulcient movement of compression is imparted to the springs 266 to hold the latches 252 in positions to engage the projections 254 until the slide 49 has been lowered far enough to carry the wipers away from the shoe bottom and to permit the springs |48, |64 to return the supporting members |38, |49 to their initial position. Thereafter in the lowering of the slide 49 the nuts 264 engage the projections 262 and swing the latches 252 outwardly to release the holders, whereupon the latter are returned to their starting positions by the springs ||8,- |39. At this time the shoe is supported by the members |38, |40 so that the wipers move in their appointed paths without contacting with the overlasted margin of the upper, thus avoiding any danger of displacement of the upper by the outward movements of the wipers.
In the operation of the machine, briefly summarized, after wipers 96, 98, suitable for the style and size of shoe to be operated upon, have been mounted on the brackets '|4, 84 and have been heated to the desired temperature, and after proper adjustments of the brackets 14, 84 and the gages |68 have been made, the operator places a shoe bottom downward upon that pair of supporting members |38, |40, which is in its lowerlnost position, While the invention is not limited to the particular use illustrate-d, the shoe herein shown is of that type in which the marginal portion of the upper is secured in lasted position along the forepart and shank portions of the shoe by an adhesive and in which an outsole is thereafter cemented to the lasted margin of the upper. In accordance with the illustrated practice, the t-oe and heel ends of the shoe are lasted before the side lasting operation is performed, although it will be understood that so far as the present invention is concerned its utility is not dependent upon one or both of these toe and heel lasting operations having been performed before the shoe is presented to the machine.
After placing a shoe in position to be operated upon, as above described, the operator starts the power operation of the machine, whereupon the slide 40 at that side of the machine where the shoe is placed, is elevated, and the slide at the other side is lowered. As the slide 40 is elevated the levers 2|6, 226 are swung by reason of the engagement of the rolls 230 with the stationary plates 232 as hereinbefore described, in directions to move the gripper jaws 220 upwardly until the adjustable stops 246, carried by the levers 2|6, engage the bottom faces of the wipers 9S, 98, each screw 245 being independently adjustable to limit upward movement of its associated gripper jaw. Thereafter, as the levers 226 continue to swing in the same directions the springs 234 are operated to move the gripper jaws toward the wipers and to clamp the opposite side portions of the margin of the upper against the inner side faces of the wipers. Substantially at this time in the upward movement of the slide 40 the shoe is stopped by the abutment members 28, 30 Vand the brackets |92 secured to the wipers engage the stops |94 on the gaging members |98. Thereafter as the slide 40 continues its upward movement, the shoe-supporting members |38, |40 are depressed against the resistance of their springs |48, |64 and the holders 92 and 94 are moved toward each other by the swinging of the parallel links 88, 90, about their pivotal connections to the brackets 74, 84. The wipers and grippers are thus moved inwardly and in this movement impart a pull to the upper to conform it tightly to the contour of the shank portion of the last and also to conform it tightly to the curvatures of the last at the top and sides of the forepart. It will be understood that during the inward movement of the wipers and grippers to pull the upper slipping of the upper relatively to the wiperszand grippers will occur if the resistance to such movement resulting from the gripping pressure of the wipers and grippers on the upper is overcome by the force of the pull applied. Such inr ward movement of the wipers and grippers occurs only against the resistance of the light springs |30 which act to hold the brackets |92 in engagement with the stops |94. The stops |94 are adjusted to position the wipers at this time with their upper-engaging faces located below the bottom face of the insole so that, as the wipers move inwardly, they do not press the marginal portion of the upper upon the insole. At a predetermined time in the inward movements of the wipers and grippers and preferably at the time when they have substantially completed their upper-pulling movements the upwardly moving rods 208 engage the stops 2|2 and elevate the gaging members |96 to move the stops |94 out of engagement with the brackets |92, and substantially at the same time the downwardly extending arms 250 of the levers 2|6 engage the abutment piece 248 on the slide 64. The springs |30 then act to move the wipers upwardly to press the margin of the upper against the insole after which, as the slide 40 continues to move upwardly, further swinging movements are imparted to the parallel links 88, 90, to move the wipers farther inwardly over the insole in wiping and pressing engagement with the upper, the levers 2|6 being also swung about their axes 2|4 to lower the gripper jaws and thus to insure release of the upper by the grippers as the wipers continue their inward movements. Just after the wipers are forced up by the springs |30 to press the margin of the upper upon the insole the bushings ||4 on the rods ||2 engage the bushings |28. The springs 8 are accordingly compressed during the latter part of the wiping action and therefore subject the upper to increasing pressure at that time. The marginal portion of the upper is thus firmly pressed against the insole as it is wiped inwardly by the heated wipers 9S, 98, which act also to iron out any surface irregularities in the' upper.
The machine comes automatically to a stop With the shoe under pressure and while the shoe is held under pressure the operator presents a shoe to the other half of the machine. The shoe will be permitted to remain under pressure long enough to render the heat effective on the cement so that when the shoe is released from pressure the cement Will have set rmly enough to maintain the upper securely in lasted position. When the machine is again started the latches 252 hold the wipers against outward return movements, in the downward movement of the slide 40, until the springs |48, |64 have returned the supporting members |38, |40 to their initial positions. Thereafter, the latches 252 release the holders 92 to the action of the springs ||8, |30, the Wipers being thus returned to their starting position Without contacting with the overlasted margin of the upper or in any case without any substantial pressure on the upper.
