48 Claims.
This invention relates to machines for shaping uppers over lasts, and is herein illustrated as embodied in a lasting machine of the same general character as disclosed in United States Letters Patent No. 2,075,852, granted on April 6. 1937, upon an application of mine, but modified in certain respects as further disclosed'in Letters Patent No. 2,101,069, granted on December 7, 1937, upon another application of mine. It is to be understood, however, that the invention is not limited to machine organizations of the character exemplified by such prior disclosures.
v An object of theinvention is to provide in a lasting machine means adapted to operate in a rapid and satisfactory manner on high-class work to last not only the toe portion of the shoe, but also the sides of the forepart extending heelwardly of the toe portion, so that the entire forepart as far as the beginning of the shank portion is lasted by the machine. To this end, the machine herein shown comprises toe-lasting mechanism and opposite side-lasting mechanisms constructed and arranged to act on the shoe in .a novel cooperative relation to one another, each v 25 of these several mechanisms, in the illustrated embodiment of the invention, including a gripper for pulling the upper tightly over the last in response to heightwise movement of the last and ;means for laying the margin of the upper in- 30 wardly over an insole on the last into position to be secured to the insole by an adhesive. For thus laying the margin of the upper over the insole the toe-lasting mechanism in the construction shown is provided with toe-embracing wipers 35 movable lengthwise and laterally of the shoe in the same manner as heretofore in machines of the illustrated type and each of the side-lasting mechanisms also is provided with an inwardly movable wiper. In order to insure against any 40 objectionable wrinkling of the margin of the upper at the sides of the forepart, the toe wipers are so extended as to overlap intheir operative movements substantial portions of the margin of the upper operated upon by the side wipers; and 45 since it is considered preferable for the best results that the margin of the upper be laid over the insole first beyond the toe portion of the shoe, i. e., in the vicinity of the ball portion, the construction is such that the side wipers are operated 50 before the toe Wipers and are then retracted to avoid interference with the toe wipers.
In order to last the sides of the shoe as far heelwardly as required, the opposite side-lasting mechanisms are arranged to operate on portions 55 of the shoe where the side edges of the shoe bottom curve inward heelwardly of the ball line; and their wipers, relatively to which the toe wipers are movable as above described, have components of movement lengthwise of the shoe to- (50 ward its toe end as they are moved inwardly over the insole, so that the direction of the wipe at each side is approximately at right angles to the edge of the insole. To accomplish that result, in the construction herein shown, the side wipers are operatively movable in paths that are curved about axes extending heightwise of the shoe. The opposite side-lasting mechanisms, moreover, prior to their operations on the shoe, are moved inwardly from initial retracted positions to positions determined by engagement with the inwardly curved sides of the shoe heelwardly of the ball line, these movements, as illustrated, being also in paths curved as above described with components in directions lengthwise of the shoe. Accordingly it results, by reason ofthe shape of the shoe, that the mechanism which operates at the inner side of a right or a left shoe moves somewhat farther in its curved path before it is stopped by the shoe than the mechanism at the outer side of the shoe, and its wiper therefore isso positioned that when it thereafter operates on the shoe it has a greater component of movement lengthwise of the shoe than the wiper of the other mechanism, as is desirable'by reason of the more pronounced inward curvature of the edge of the shoe bottom at the inner side of the shoe. In accordance'alsowith a feature of the invention the opposite side-lasting mechanisms are thus moved inwardly toward the shoe by spring means which is tripped to render it operative prior to the starting of the power operation of the machine, thus affording the operator the opportunity thereafter'to inspect the work and to present the margin of the upper in proper relation to the grippers with which these mechanisms are provided before starting the machine.
It is a further characteristic of the construction herein shown that the gripper which grips the toe end of the upper and the grippers included in the side-lasting mechanisms are conveniently closed on the upper by a member movable by the operator and common to all of them. To facilitate presentation of the margin of the upper to the several grippers, the invention provides novel means for preventing this member from acting on the side grippers when it is operated to close the toe gripper, so that the operator may present the upper first to the toe gripper alone and may thereafter direct his attention to the side grippers. For the purpose in View the construction disclosed comprises means controlled by the inward positioning movements of the side-lasting mechanisms for rendering the above-mentioned member effective to close the side grippers only after those mechanisms have received their positioning movements.
The. above and other features of the invention, including novel means for holding the side grippers closed and for thereafter releasing them, novel means for imparting closing movements to these grippers, and Various novel details of construction and combinations of parts will now be more particularly described with reference to the accompanying drawings and thereafter pointed out in the claims.

In view of the disclosures in the above-mentioned Letters Patent and other Letters Patent hereinafter referred to, the drawings show only as much of the machine as is necessary for an understanding of the present invention, and the construction and operation of such parts as are common to the prior disclosures will be only briefly described. The shoe to be lasted at the forepart is mounted on a toe rest 2 (Figs. '7 and 8) which is movable downwardly with the shoe against the resistance of a spring 4, and on a heel-end support comprising a post 6 (Fig. ,1) provided with a pin 3 to enter the spindle hole in the last, the post being supported on a slide l movable downwardly also with the shoe against the resistance of a spring I2. The shoe is clamped about its heel end by a flexible heel band 14 controlled by mechanism such as disclosed in Letters Patent No. 2,101,069, the heel band and its controlling mechanism being supported on a slide l6 which is movable in directions lengthwise of the shoe along two rods i8 (only one of which is shown) carried by the vertically movable slide ID. The slide it is moved toward the left to carry the 1 heel band toward the shoe by a spring 20 when view of one of the side grippers I (heel band is thus in engagement with the shoe.
, The latch 22is operated to release the slide and thus to cause the heel band to be moved toward the shoe and'the shoe to be carried into engagement with the band as above described prior to the starting of the power operation of the machine. For this purpose there is provided mechanism substantially as disclosed in Letters Patent No. 1,843,232, granted on February 2, 1932, upon an application of mine, which includes a plunger 26, shown in Fig. 3 but omitted from Fig. 1, arranged tobe moved rearwardly by the knee of the operator against the resistance of a'spring 28.. The plunger is provided with a stem 39 the-rear end of which is arranged to abut against a finger 32 fast on a rod 3 5 which is movable lengthwise .in a bracket 36 on the frame. This rod carries a wedge member 38 extending through a slotin the bracket to prevent the rod from turning and arranged to engage a roll carried by an arm 50 fast on a rock shaft 42. By means not herein shown this rock shaft is connected to the lower end of a rod 44 (Fig. 1) the upper end of which is connected to the latch 22, so. thatin response to the turning of the rock shaft by. the rearward movement of the wedge member 38 the latch 22 is swung downwardly against the resistance of a return spring 46 to release the slide I6. In case the machine should be started accidentally prior to such release of the slide 16, the slide will be released automatically at the beginning of the cycle. posethere is provided a lever 48 (Fig. 3);mounted to swing about a pin 50 and provided at its upper end with a tooth which extends into a notch in the rod 34, the lever being provided at its lower end with a roll 52 arranged to be engaged by a cam 54on the periphery of a cam wheel 56 fast on a cam shaft 58 with which a machine of the illustrated type is provided. It will be evident that immediately upon the starting of the machine the cam 54 swings the lever 18 to effect the 7 the upper around the toe and to some extent also heelwardly of the toe portion and to wipe it heightwise of the last toward the'edge of the insole in response to depression of the last and shoe, and wipers M- for wiping the margin of the upper around the toe inwardly over the insole, these wipers being of such lengths as to overlap also substantial portions of the bottom of the shoe extending heelwardly of the toe portion. The band For this pur-' and the wipers are supported by a casting 66 (Fig.'
1) adjustable as heretofore about an axis extending widthwise of the shoe, and this casting is supported by a slide 68 adjustable also as heretofore in directions lengthwise of the shoe to position the toe-lasting mechanism-in proper relation to shoes of different sizes. As fully disclosed in Letters Patent No. 2,075,852, the wipers 64 are advanced lengthwise of the shoe and are closed inward laterally of the shoe by mechanism including a rock shaft 10 (Fig. 2) operated by a cam (not shown) on the cam shaft 58. Preferably the wipers are maintained in a heated condition by an electrical heating unit I2 mounted in a cover plate It; which is fast on the casting 66 over the wipers.
There is further provided means constructed substantially as disclosed in the last-mentioned Letters Patent for clamping or gripping the margin of the toe end of the upper prior to the starting of the power operation of the machine, so that in response to the depression of the last a pull heightwise of the last is applied to the upper as it is wiped upwardly by the toe band 62. This clamping means comprises cooperating clamp members '36 and 18 (Figs. 2 and 7) arranged to serve as a gripper for gripping the margin of the upper, the member I8 being movable toward the member 16 thus to grip the margin. For this purpose the member 18 is secured to a pair of arms 8!] which are operated, as fully disclosed in the last-mentioned Letters Patent, by the turning of a rock shaft 82 rotatable in bearings on the cover plate 14. This rock shaft carries crank arms 84 connected by links 86 to blocks 88 which are pivotally mounted on pins 90 carried by the arms and are movable by the crank arms against the resistance of springs 92 first to move the arms 81] a limited distance lengthwise of the shoe and then to swing them to cause the member I8 to clamp the upper against the member I6, the blocks 88 being then movable about the pins 99 against the resistance of springs 94 to apply the final clamping pressure yieldingly to the upper. The rock shaft 82 is turned by the operation of a lever 56 fast on the front end thereof in response to depression of a treadle 98 against the resistance of a spring I09. In the construction herein shown the lever 96 is connected by a'fiexible cable I02, not directly to the treadle 98, but to one arm of a lever I64 mounted to turn about a rod I06 (Fig. 3) on the frame of the machine, the lever I04 being connected to the treadle 98 by another flexible cable I68. After the clamp member I8 has been moved into clamping engagement with the upper by depression of the treadle 98, it is locked in upper-clamping or gripping .position until a predetermined time in the power operation of the machine by a latch III) (Fig. 1) carried by the lever 96 and cooperating with a lug H2 formed on a plate H4 which turns with the wiper-operating rock shaft I0.
Depression of the shoe is effected substantially at the beginning of the power operation of the machine by a toe presser foot IIS and a heel presser foot H3 arranged respectively to engage the toe and heel ends of the insole. The toe presser foot is supported by an arm I20 rigidly connected to vertically alined rods I22 and I24 mounted for vertical movements and for turning movements in bearings in the frame. The arm I29 occupies initially a position in which the toe presser foot I it is retracted rearwardly from over the shoe bottom, and the operator swings the arm forwardly to carry the presserfoot into position over the shoe by means of a handle I 26. Such forward movement of the arm serves to start the power operation of the machine, as disclosed in Letters Patent No. 1,843,232, whereupon the toe presser foot is carried downward simultaneously with the heel presser foot I I8 to effect the depression of the shoe. The heel presser foot H8 comprises a rod supported on a carrier :28 which is f t o a od I391I1Dunted for vertical movements and for turning movements in hearings in the frame. As the rod I38 starts downward it is quickly turned to swing the presser foot II8 into position over the shoe by means such as disclosed in Letters Patent No. 1,843,232, which may be referred to also for disclosure of means whereby the rods I22, I24 and I30 are operated by the cam shaft 58. As the shoe is depressed it may be tipped laterally to insure that it will be properly positioned relatively to the toe wipers 64 by a member I32 (Figs. 1, 7 and 8) operated and controlled as disclosed in Letters Patent No. 2,075,852.
For purposes of this invention the machine is provided with a pair of side-lasting mechanisms indicated generally by the reference characters I34 (Fig. 2), for pulling the upper and wiping its margin inwardly over the insole at the sides of the forepart heelwardly of the toe portion of the shoe, so that the entire forepart of the shoe is lasted by the machine. Each of these mechanisms is supported on a bracket I36 fast on the casting 66, each bracket beingprovided with a dovetailed portion 93% (Figs. 3 and 4) which provides a guideway for a slide' I40 on which the operating parts of the corresponding sidelasting mechanism are supported. By movement of the slides I 46 along these dovetailed portions E38 the two side-lasting mechanisms are prelimi narily adjustable in directions lengthwise of the shoe to position them in proper relation to shoes of different sizes.
thereon are adjusted as and for the purpose above described. To hold the slides in adjusted positions one of the rods I48 is engaged by a set screw I58 threaded in the frame and having a pin For effecting such an adjustment, arms I42 (Fig. 3) which are integral with I68 extending transversely thereof for turning it. y
In order to indicate to the operator the positions of the side-lasting mechanisms with respect to this adjustment, an arc-shaped projection I52 on the front bracket IE6 is provided with a scale, as shown in Fig. 2, to cooperate with a finger I64 pivotally mounted on the bracket, this finger be-.
ing pressed at all times by a spring I58 against alug I 56 formed on one of the slides I49. It will therefore be evident that any adjustment of the slides I46 is accompanied by a correspond ing swinging movement of the finger I64, so that,
by reference to the scale the positions of the slides are indicated.
Each of the side-lasting mechanisms comprises a gripper I'Iil (Fig. 4) for gripping and pulling the upper, and a wiper IIZ for wiping the margin of the upper inwardly over the insole, these parts being supported as hereinafter described on a carrier I14 which is movable toward and from the shoe along an upraised guiding portion I I6 (Fig. 1) of the slide I46. The carrier and its guiding means are curved about an axis extending heightwise of theshoe so that in their movement inwardly toward the shoe the gripper and the wiper have components of movement lengthwise of the shoe toward the toe end of the latter. Initially the two carriers I14 are retracted from the shoe, as illustrated in Fig. 2, to afford ample to the shoe.
inward movement of each carrier is limited by engagement of the shoe with a clamp member or bumper I18 (Figs. 6 and 8) fast on a block I which is swiveled on a plate I82 fast on the carrier I14, by means of a tongue and groove connection I83 with the plate, to permit it to turn with the member I18 about an axis extending heightwise of the shoe and thus to adjust itself By reference to Fig. 6 it will be seen than the shoe-engaging face of the member I18 is curved somewhat lengthwise of the shoe, the member being arranged to engage the upper ina location where the side of the last curves inwardly towardthe shank portion of the shoe heelwardly of the ball line.
Each carrier 414 is thus moved inwardly toward the shoe by a lever I84 (Figs. 1 and 3) pivotally mounted between its ends on a pin I8fi supported in the bifurcated lower end portion of the previously mentioned arm I42. The upper end of each ,lever I84 is connected to the carrier associated therewith through a link l88, as more particularly hereinafter described, so that the carrier is operated by the lever. At its lower end each lever I34 the lever and the arm. Between their opposite ends the two arms I92 are pivotally connected ,to the outer bifurcated ends of toggle links N4 the inner ends of which are pivotally connected together by a rod I95 (Figs. 1 and 3) on which is pivotally mounted a depending link I93. By reference to Fig. 1 it will be seen that this link comprises arms 200 and 262 spaced a considerable distance apart and mounted on the opposite ends of the rod I96, the two arms being connected together by a web 244. A roll 2% mounted on the arm 20!! is guided between parallel lugs 268 on the frame to control the toggle links I94 and thus maintain the arms I92 at all times at substantially equal distances from a vertical plane midway between the two rods 448. A collar 289 (Fig. 1) fast on each of the rods M8 holds the hub portion of the arm I92 against the arm I46 adjacent thereto, so that in the movements of the rods I48 to adjust the slides I49 lengthwise of the shoe as hereinbefore described the arms I92 and the connections between them and the carriers I14 move with the rods. In this adjustment the toggle links I94 slide along the rod I96.
At its lower end the link I98 is pivotally connected to the front end portion of a lever Zltl the rear end of which is fast on a rock shaft 2 I2 supported in bearings in the frame. 2 I4 connected to the rock shaft 212 tends to swing the lever 3H0 downwardly and thus through the toggle links I94 to swing the arms I92 and the levers I84 in the directions to move the carriers I 14 toward the shoe. Initially, however, the lever 21:: is held upraised, with the carriers in their retracted positions, by means of a lever 2H3 provided with a plate 218 arranged to underlie an edge portion of a plate 229 on the lever 2m,- as illustrated in Fig. 3. The lever 2I6 is swung to release the lever 2 I0, and thus cause the carriers I14 to be moved toward the shoe, by movement of the same plunger 2% through the action of which the slide I6 supporting the heel band is initially released as hereinbefore described. The arrange-.
A torsion spring mer t, however, is such that the lever 2I0 is released only'iri response to further movement 'of' the plunger 25 after the plunger has been moved far enough to release the heel band slide. For this purpose the rod 34 operated by the plunger is spaced initially from the lower end of the lever 25%, as shown in Fig. 3, and engages the lever only after the slide I6 has been released, further movement of the red by the plunger 26 then serving at thewill of the operator to swing the lever zit far enough to carry the plate 2I8 out from under the plate 220. Such movement of the lever 2H5 is effected against the resistance of a spring'222 which returns the lever when permitted and holds it normally in a position determined by its engagement with a stop screw 224. It will be evident that after releasing the heel band slide I6 the operator may delay the release of the lever us until after the toe end of the upper has been gripped by depression of the treadle 9 In case the lever 2H3 should be released prematurely, it may be returned into position to be again held by the lever Hit by means of a hand lever 226 mounted on the rock shaft H2 and arranged to act on a pin 228 to turn the shaft, this pin extending from the shaft into a notch 23cm the hub of the lever. The hand lever 226 may be moved lengthwise of the shaft 2jl2 far enough to disconnect it from the pin 228 and thus prevent it from being swung by the shaft in the normal operation of the machine. The previously mentioned cam 54, which in the event of premature starting of the machine serves to release the heel band slide I6, also serves under those conditions to release the lever 2H3, thus preventing breakage of parts of the machine.
Each gripper I10 comprises a jaw 232 (Fig. 4) i jaw 232 is curved lengthwise of the shoe in approximate conformity to the curvature of the edge of the shoe bottom in the location where the gripper operates, and in this jaw is provided a recess 240 into which portions of the margin of the-upper are forced by a tongue 242 on the jaw 234 to insure that the upper will be firmly gripped. The jaw member 232 is mounted on a block 244 and is provided with a tongue 246 curved about an axis extending heightwise of the shoe and extendinginto a complemental recess formed in the block 244, so that the gripper is swiveled on the block for adjustment about that axis for better conformity to the shapes of different shoes. The head of a screw 248 threaded in the block 244 is arranged to engage the upper face of the jaw member 232 and thus to clamp the gripper in adjusted position on the block.
Each block 244 is mounted on a pin 250 which is rotatable in ears 252 (Figs. 2 and 4) formed on the carrier I14 and is fastened to the pin by a set screw 254. The space between these ears is greater than the width of that portion of the block which is mounted on the pin, and accordingly the gripper may be adjusted along the pin in directions lengthwise of the shoe relatively to the wiper I12, the block being held in adjusted position by the set screw. A screw 256 (Fig. 2) threaded in an ear on the block 244 is arranged to rest at its lower end on the carrier I14 and may be used to adjust the gripper heightwise of the shoe relatively to the wiper I12 by swinging the block 244 about the axis of the pin 250'.
Each gripper jaw 234 has two upwardly extending arms 258 pivotally connected by a pin 268 (Fig. 4) to a block 262 between the arms, this block being pivotally mounted on a pin 264 extending at right angles to the pin 268 and carried by the yoke-shaped head 266 of a rod 268 which extends through a slot 218 in a U- shaped member 212. Surrounding the rod 266 between its head 266 and the member 212 is a compression spring 214, and threaded on the rod are two nuts 216 one of which engages the member 212 on the opposite side thereof from the spring. The two arms of the U-shaped member 212 are rotatably mounted on pins 218 which are fastened in upwardly extending arms 288 of a gripper-closing member or device 282 mounted to swing about the pin 258. It will thus be seen that by swinging movement of the member 282 in a counterclockwise direction (Fig. 4) the gripper jaw 234 is swung toward the jaw 232 to grip the margin of the upper by movement of the arms 288 in a direction toward the last, such swinging movement of the jaw being effected against the resistance of a jaw-opening spring 284 (Fig. 2) connected at one end to the pin 26!) and at the other end to the block 244. After the jaw 234 has arrived in upper-gripping position further movement of the member 282 serves to compress somewhat the spring 214 by moving the U-shaped member 212 along the rod 268, so that the upper is yieldingly gripped. To maintain the jaw 234 in upper-gripping position the member 282 is locked against reverse swinging movement by a latch 286 lying in a slot formed in an arm 288 of the member 282 and pivotally mounted on a pin 298 in the arm, this latch being controlled by a spring 292 which swings its lower end over the top of a plate 294, supported as hereinafter described, as soon as permitted by the swinging of the member 282. Movement of the latch 286 by the spring is limited by engagement of the upper end portion thereof with a stop screw 296 in the arm 288. It will be understood that engagement of the lower end face of the latch 286 with the plate 294, which serves as an abutment for the latch,
prevents the reverse swinging movement of the member 282. A stop screw 298 (Fig. 2) threaded in the member 282 is arranged to rest at its lower end on the top of the carrier I14 and thus to cooperate with the spring 284 to determine the normal position of the member. It will be evident that the connections between the arms 258 of the jaw 234 and the rod 268, including the provision for turning of the block 262 about the pin 264, permit adjustment of the gripper relatively to the block 244 in the manner hereinbefore described.
The two gripper-closing members 282 of the opposite side-lasting mechanisms are operated to close the gripper jaws 234 on the upper as above described by depression of the same treadle 98 which is used, as hereinbefore described, to effect the gripping of the toe end of the upper by the members 16 and 18. For this purpose the lever I84, operated by the treadle through the flexible cable I88, is provided with two arms 388 (Fig. 3) connected by flexible cables 382 to hellcrank levers 384 pivotally mounted on studs 386 supported in upstanding ears 388 on the carriers I14. These bell-crank levers are movable against the resistance of springs 3| 8, and each of them carries a pin 3I2 arranged to engage the hook-shaped end of a link 3I4 the other end of which is pivotally mounted on a depending arm 3I6 of the member 282. A stud 3I8 threaded in the carrier I 14 determines the normal position of the bell-crank lever 384 by engagement with one arm thereof. It will be evident that by engagement of the pin 3I2 with the link M4 the member 282 is swung in the direction to impart closing movement to the jaw 234 in response to the swinging of the bell-crank lever 384 effected by the depression of the treadle 98. The two links 3I4, however, rest on upstanding lugs 328 formed on the slides H48, and when the opposite sidelasting mechanisms are in their initial retracted positions the positions of the links 3I4 are such that their hook-shaped ends are not engaged by the pins 3I2 when the bell-crank levers 384 are swung by the first movement of the treadle 88 to effect the gripping of the upper at the end of the toe. Accordingly this movement of the treadle has no effect on the gripper jaws 234. When the side-lasting mechanisms are moved inwardly toward the shoe the lugs 328 engage inclined faces 322 (Fig. 4) on the links 3I4 and swing these links upwardly so that their hookshaped ends are in the paths of movement of the pins 3I2 when the treadle 88 is depressed a second time. Accordingly this second depression of the treadle, after the side-lasting mechanisms have been released by movement of the plunger 26 and have been moved inwardly toward the shoe, closes the jaws 234 on the upper.
Each wiper I12 consists of a resilient plate fastened to one end of a slide 324 the side edges of which are curved similarly to the carrier I14, the slide being mounted in correspondingly curved guideways in the carrier to move relatively to the carrier widthwise of the shoe in a path curved similarly to the path of movement of the carrier so that the wiper will have a component of movement lengthwise of the shoe toward the toe end of the latter as it is moved inwardly over the insole. The inner edge portion of the wiper, which first engages the upper, is curved lengthwise of the shoe in approximate conformity to the curvature of the corresponding edge of the shoe bottom, and this edge portion of the wiper is also upturned to facilitate its movement over the edge of the shoe bottom. Portions of the wiper may be sprung downwardly more or less for better conformity to the contour of the shoe bottom by means of screws 326 and 328 threaded in the slide 324 and engaging the wiper at their lower ends. The outer ends of the two slides 324 are connected to the levers M4 by the previously mentioned links I88 which have ball-shaped ends lying in corresponding sockets provided respec tively on the levers and on the slides, so that wiper-operating movements are imparted to the slides by these levers. When these levers, however, are operated in the manner hereinbefore described to move the carriers I14 and the parts thereon inwardly toward the shoe upon release of the lever 2I8 by the movement of the plunger 26, the slides 324 are prevented from moving relatively to the carriers I14 by springs 338 each of which is connected at one end to the slide and at the opposite end to the carrier and lies partly in a slot formed in the slide. Accordingly the inward movements are imparted to the carriers through these springs which are strong enough to prevent them from yielding at this time. At the time in the cycle of operations when the wipers E12 are moved inwardly over the shoe bottom by the slides 324 the springs 338 yield to permit such movements of the slides. The levers I84 are operated for this purpose by further downward swinging movement of the lever 2I8 efiected by a path cam 332 (Fig. 3) formed in the cam wheel 56. This cam engages a roll 334 mounted on a lever 336 which is connected to the lever m by a link 338. This link consists of two members t lt! and 3H pivotally connected respectively to the lever 25!] and the lever 336, the member 342 being movable relatively to the member 348 against the resistance of a spring 344 in the event of unusual resistance of the shoe to inward movement of the wipers H2. The spring 344 abuts at one end against the member 340 and at its other end against a washer 346 held by a nut 348 on one end of a rod 359 the other end of which is threaded in a wedge member 352 movable in an opening extending transversely of the member 36!! and supported on a ball bearing 35%. A roll 35% mounted on the upper end of the member 3 52 rests on an inclined wedge face 358 of the wedge member 352. It will accordingly be evident that in the event of unusual resistance to downward movement of the member 340 the wedge member 352 will be forced toward the right (Fig. 3) against the resistance of the spring 344 by the action of the roll 356 thereon, permitting the member 342 to be moved farther downward relatively to the member 340 by the cam 332. This path cam is enlarged at 360 to permit such downward movement of the lever 336 as occurs when the lever 2H] is released by the plunger 26 to cause the side-lasting mechanisms to be moved inwardly toward the shoe prior to the starting of the power operation of the machine.
The plates 294 previously referred to as engaged by the latches 286 to hold the gripper jaws 234 in their closed positions are fastened to lugs 362 extending upwardly from the slides 324. Accordingly when these slides are operated to move the wipers I12 inwardly over the shoe bottom the plates 294 are carried out from under the latches to permit the grippers to open and release the upper. This operation is timed to occur just as the side wipers begin to wipe the margin of the upper inwardly over the insole.
A shoe to be operated upon by the abovedescribed machine will preferably have been assembled and pulled over in the customary manner, and it may or may not have been previously lasted along the shank portion. The shoe herein shown for illustrative purposes is to be lasted at the shank portion as well as at the heel end after it has been operated upon by the machine. Before the shoe is presented to the machine, or at least prior to the operation of the machine thereon, such trimming of the toe-end portion of the upper materials as is customary when the upper is fastened to the insole by an adhesive will have been performed and suitable adhesive will have been applied around the toe and along the sides of the forepart. As herein illustrated, all the pulling-over tacks are removed prior to the operation of the machine on the shoe, although, if preferred, tacks fully driven at the sides of the toe in the pulling-over operation may remain in the shoe.
After mounting the shoe on the heel pin 8 and the toe rest 2 the operator releases the heel band slide it by pres ing against the plunger 25, thus causing the heel band I4 to be applied to the shoe and the shoe to be positioned lengthwise as determined by the band, in the manner hereinbefore described. The operator then spreads the margin of the upper at the end of the toe out- Wardly over the clamp member 16 of the toe gripper and by depression of the treadle 98 moves the cooperating clamp member 18 into uppergripping position, this member being locked in that position by engagement of the latch H0 (Fig. l) with the'lug H2. Thereafter the opera- 'tor again'presses 0n the plunger 26 to release These mechanisms move inwardly in curved paths, as described, and since the mem bers I18 engage the shoe in locations where its opposite sides curve inward heelwardly'of the ball line, the two mechanisms assume the proper re lation to either a right or a left shoe for thereafter operating thereon with the best results, the mechanism which operates at the inner side of the shoe moving somewhat farther inwardly than the mechanism at the outer side by reason of the shape of the shoe. After the opposite side-lasting mechanisms have thus assumed positions determined by the shoe, the operator again depresses the treadle 9% to close the side grippers on the margin of the upper, these grippers being locked in upper-gripping relation by engagement of the latches 286 (Fig. 4) with the abutment plates 294. The operator then swings the arm 32E? forwardly by means of the handle I26 to bring the toe presser foot H6 into position over the shoe, thereby starting the power operation of the machine.
Immediately after the starting of the machine the toe presser foot I I6 and theheel presser foot H8 are moved downwardly to depress the shoe against the resistance of the springs l and I2,
the heel band and its support moving downwardly with the shoe- As a result of such depression of the shoe the upper is pulled tightly over the last by the toe gripper and the side grippers and it is wiped upwardly about the toe portion of the last by'the toe band 952. The positions of the parts at the end of such downward movement of the shoe are illustrated in Figs. 7
and 8. Thereafter the side wipers 112 are moved inwardly to wipe the margin of the upper over the insole in the manner illustrated in Fig. 9 by the action of the cam 332 on the mechanism which operates the wiper-carrying slides 324. As these wipers start to wipe the upper over the edge of the insole the side grippers are caused to release the margin of the upper by reason of the fact that the plates 29$ are carried by the slides 324 out from under the latches 286. It will be evident by reference to Fig. 9 that by reason of the relation of the side-lasting mechanisms to the opposite sides of the shoe, determined by the shape of the shoe as hereinbefore explained, that wiper H2 which operates at the inner side of the shoe has a greater component of movement lengthwise of the shoe toward its toe end than the other wiper, as is desirable for the best results. After wiping the margin. of the upper inwardly the side wipers are immediately retracted from over the shoe bottom by the cam 332 and the side-lasting mechanisms are re-' wipers start to wipe the upper over the insole the toe end of the upper is released by the toe gripper by reason of the fact that the lug H2 moves out from. under the latch IIU. While the toe wipers are thus over the shoe bottom the presser feet H6 and H8 are moved upwardly slightly to permit the shoe to be forced more firmly up against the toe wipers by the spring 4, the support for the heel end of the shoe being preferably restrained from upward movement at this time by mechanism such as disclosed in Letters Patent No. 2,075,852. At this point the machine is preferably brought automatically to a stop by controlling mechanism of the character disclosed in the last-mentioned Letters Patent to permit the overwiped margin of the forepart of the upper to remain for a short time under the pressure of the heated toe wipers, after which the machine is automatically started again to permit it to complete its cycle of operations. During the remainder of the cycle the parts of the machine not already in their starting positions are returned to such positions, the shoe being released from pressure and then removed from its support by automatic shoe-removing mechanism with which machines of the illustrated type are provided.
