48 Claims.

This invention relates to. lasting machines, and more particularly to machines for lasting the toe ends of shoes. An object of the invention is toprovide a machine so constructed that in lasting 5 shoes made on ordinary lasts satisfactory results will be obtained in the lasting of each shoe and substantially uniform results in operating on 'different shoes without the necessity for the operator to exercise any great care or to spend any substantial amount of time in properly presenting each shoe to the machine or in relatively adjusting the shoe and the lasting means. The invention is herein illustrated as embodied. in a machine in which the lasting operation is performed by the operator, but in various aspects the invention is also applicable to machines having power-operated lasting means.

The machine herein shown is provided, as common heretofore, with wipers guided for advancing and closing movements in predetermined paths lengthwise and laterally of the shoe and formed to embrace the toe end of the shoe closely at the edge of the shoe bottom, the wipers being movable heightwise of the shoe to perform what is known as the up-wiping operation before they are further advanced and closedto wipe the margin of the upper inwardly over the shoe bottom. Satisfactory results in the lasting operation require such a relation between the shoe and the wipers that the wipers, when advanced and closed a certain distance, will properly embrace the toe and will thereafter wipe the margin of the upper inwardly over the shoe bottom with adequate pressure all around the toe. To this end, the machine herein shown is so constructed as to determine accurately in certain respects the re.- lation between the shoe and the paths of movement of the wipers before the wipers operate on the shoe, but to permit in one respect a relative movement of the shoe and the wipers into proper relation as an incident to the lasting operation. As illustrated, the position of the shoe lengthwise is determined by an end gage in contact with its toe-end face, and the relation of the bottom of its forepart to the plane of the wipers is determined by a member engaging that portion of the shoe and against which the shoe is clamped by a toe rest. At its heel end, more over, the shoe is engaged by a heel. rest which determines invariably for different shoes, whether rights or lefts, the position of the heel end laterally. The shoe, however, is further so controlled as to permit its toe end to adjust itself laterally to the wipers, thus avoiding the necessity for any exact positioning of the shoe in this respect by the operator or for the provision of special means for predetermining the position of the toe end laterally. To permit and facilitate such lateral movement of the toe end of the shoe, the shoe sup-porter holder, including the bottom-engaging member and the toe rest, is mounted to swing with the shoe about an axis in the vicinity of its heel end in response to pressure of the wipers on one side or the other of the toe exteriorly of the shoe bottom as the wipers are closed about the toe. The shoe may thus adjust itself readily to the wipers not only prior to the upwiping operation, but during that operation, sothat regardless of the shape of the shoe at the sides of the toe the pressures of the wipers on the opposite sides will be substantially equalized. It will be evident that since. the toe end of the shoe thus adjusts itself laterally to the wipers, and since the position of itsheel end laterally is determined as above described, insurance is afforded that the wipers will properly lit the toe when advanced and closed about the toe, the wipers, of course, being properly designed with reference to a shoe positioned inthe above-described relation to their paths of movement.

To insure that in the wiping of the margin of the upper inwardly over the insole after the upwiping operation the wipers will close substantially equal distances over the. insole, the invention further provides means for preventing in the overwiping operation any such relative movement of the shoe and the wipers in a direction laterally of the. shoe as may occur in the upwiping operation. In the construction shown this means comprises a slide connected tothe shoe holder to be moved by the latter in directions laterally of the shoe, and a device controlled by the upwiping movement of the wiper support for engaging this slide to lock the shoe holder against further movement when the wipers arrive substantially at the edge of the shoe bottom.

In a further aspect, the invention relates more particularly to the control of members provided for determining the position of the shoe. In the construction shown the toe wipers are moved by the operator to perform the lasting operation, and the heel rest also is moved by the operator into engagement with the shoe, but power-operated means is provided for locking the heel restv in operative position, for operating the toe rest to clamp the shoe, and for moving the toe-end gage out-of operative position. The starting of the power-operated means results from depression of a treadle by movement of which the heel 3S1 is first applied to the shoe, and upon a sec- 0nd depression of this treadle after the lasting operation the power means is again started to cause it to unlock the heel rest and to return the toe rest and the toe-end gage to their initial positions. Various novel features of the invention are to be recognized in this organization.

The above and other features of the invention, including also novel means affording provision for withdrawal from operative position of the positioning member engaging the bottom of the forepart of the shoe, novel means for supporting the shoe and last at the cone'of the last, 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.

The machine herein shown is provided with toe-lasting means generally similar to means commonly used heretofore in lasting machines of the bed type and in most respects similar to the disclosure of United States Letters Patent No. 1,018,477, granted on February 27, 1912 upon an application of Matthias Brock. Accordingly such means need be only briefly described, and it will be further understood that the invention is not limited to the use of lasting means of this par ticular character.

For wiping the upper heightwise of the toe and for thereafter wiping its margin inwardly over the shoe bottom there are provided toe-embracing wipers 2 having wiping edges curved to conform substantially to the contour of the end and sides of the toe adjacent to the edge of the shoe bottom, these wipers being detachably secured to wiper carriers 4 (Fig. 5) mounted on a holder 6. The wiper carriers 4 are provided with cam slots 8 and Ill cooperating with rolls (not shown) on the holder 6 to determine the paths of advancing and closing movements of the wipers lengthw se and laterally of the shoe. 7 The carriers 4 are connected by links l2 to a crossbar M fast on the end of a rod It movably mounted in a cylindrical extension I8 of the holder 8 and connected by a link 2!! to a wiper-operating hand lever 22. By means of its cylindrical extension [8 the holder 6 is mounted on a support 24 (Fig. l) which is carried by a slide 26 adjustable horizontally lengthwise of the shoe along a guideway on a plate 28. The slide 26 in the construction herein shown is adjustable in that manner by means of a hand wheel 30 at the front of the machine connected by worm gearing 32 to a shaft 34 rotatable on the plate 28 and threaded in a portion of the slide 26. The wiper holder 6 may be turned about the axis of its cylindrical extension l8 by a hand crank 36, and the support 24 may be swung about a rod 38 extending laterally of the shoe by means of a hand crank 46. The wipers may thus be tipped about axes extending lengthwise and laterally of the shoe to positions such as to produce the best results in wiping the margin of the upper materials inwardly over the shoe bottom; but in view of the character of the means hereinafter described for properly positioning each shoe, any such adjustment will be rarely required.

The plate 28 is part of a slide 42 which is vertically movable in a guideway in the frame of the machine and is connected by a link 44 to a crank arm 46 fast on a rock shaft 48. Also fast on this rock shaft is a double-acting treadle 50 comprising

arms

52 and 54 arranged to be acted upon respectively by the forepart and the heel of the operators left foot. of the treadle the slide 42 and the parts supported thereon are raised to cause the wipers 2 to wipe the upper heightwise of the toe after they have been advanced and closed about the toe by the hand lever 22, and as the wipers are further advanced and closed to Wipe the margin of the upper inwardly over the insole they may be forced downwardly upon the shoe bottom by depression of the arm 54 of the treadle, as in prior machines provided with toe-lasting means of the same general type.

The position of each shoe lengthwise relatively to the paths of movement of the toe wipers is determined invariably for different shoes by a toe-end gage 56 which is part of a forwardly extending arm. of a lever 58 mounted for swinging movement about a horizontal rod 50 fast on the frame of the machine and located asubstantial distance rearwardly of the shoe, this lever being controlled by mechanism hereinafter described. Initially the gage 55 is positioned somewhat above the plane of the wipers for contact with the toeend face of the shoe as the operator presents the shoe to the machine. The height at which the shoe is thus presented is determined by a shoepositioning arm 62 supported as hereinafter described, this arm being provided at one end with three bosses 64 (Fig. 5) arranged to engage the forepart of the insole. The arm 62, therefore, has virtually a three-pointbearing on the bottom of the forepart of each shoe and accordingly determines invariably for different shoes of the same style and size the relation of the bottom 01" the toe end or forepart of each shoe to the plane of the wipers. Insurance is thus afforded that the wipers will operate with uniformly satisfactory results on the different shoes in wiping the margin of the upper inwardly over the insole. It will be understood that by use of the hand crank All the wipers may be tipped about the axis of the By depression of the arm 52 downwardly relatively to rod 38, as hereinabove described, to vary as desired the amount of downward pressure which they will apply to the margin of the upper mate: rials'at the end of the toe as compared with the pressure applied at the sides of the toe, and that by use of the hand crank 35 the wipers may be tipped laterally to vary relatively the pressures applied at the opposite sides of the toe. Such adjustments may be desirable, for example, when shoes of different styles vary substantially in shape or when there is a substantial difference in the character of the upper materials as between different lots of shoes, but it will be understood that after the wipers have been properly adjusted for shoes of a given style and character, no further adjustment will ordinarily be needed in operating upon such shoes. After the shoe has been presented with its toeend'face in contact, with the gage 56 and the bottom of its forep art in contact with the bosses 64 of the arm 62, it is engaged at the heel end by a heel rest which assists in holding it against heelward movement in the lasting operation and also serves to centralize its heel end laterally. This heel rest comprises a block 66 (Figs. 6 and '7 arranged to press on the extreme end face of the shoe anda pair of arms 68 arranged; to

engage the corners of the heel end of the shoe in locations near the heel seat. Preferably, as shown, the block 66 carries a cushion H! of felt or rubber on its shoe-pressing face and is also provided with a strip of leather 12 extending over the cushion. The block 86 is mounted on a pin 14 for limited turning movement about an axis extending laterally of the shoe, this pin being mounted on a slide '16 which is movable in directions lengthwise of the shoe in a block '18. The two arms 68 are mounted to swing toward and from each other about pins 89 in the block it and are connected by gear teeth 82 with corree spending teeth of the slide 16 so that the arms have equal movements. This slide is controlled by a spring 8 1 which tends tomove it in a direction to swing the arms 58 away from each other, its movement in that direction being limited .by a pin 85 thereon in engagement with the block 18 atthe end of a slot 86 (Fig. 8) in the block. The block '58 is supported on a bracket 8'! and is'adj'ustable along a curved guideway 88 on this bracket, the center of curvature of this guide wa-y'being located substantially at the heel-end face of the shoe when the heel rest is in contact with the shoe. The block is held in adjusted position on the bracket by a screw 90 which is threaded in the block and extends through a slot 92 in the bracket, the screw being provided with a knurled head 96 engaging-a washer 96 which bears against the bracket and has a tongue extending into the slot 92. The bracket 81 is provided with a stem 98 clamped adjustably in the upper end of an upwardly extending arm IUO of a lever I02 mounted to swing about a rod I04 on the frame of the machine. It will be understood that the bracket 8? may be adjusted upwardly'or the arm I06 and that the block 18 may be adjusted relatively to the bracket, to position the heel rest in proper relation to shoes of" different styles and sizes. The lever 52 is operated by means hereinafter described to carry the heel rest into engagement with the shoe. In this operation the block 66 arrives first in position to press on the shoe, whereupon the arms 68 are swung inwardly into engagement with the corners of the heel end of the shoe'by the action of the slide 16 thereon as the arm I continues its movement against the resistance of the spring 84. The arms thus determine invariably for different shoes the position of the heel end of each shoe laterally, whether the shoes be rights or lofts and regardless of the styles or sizes of the shoes; and as the heel end of each shoe is thus positioned, a point on the heel seat midway between the two arms 68 lies in the vertical plane in which the meeting point of the edges of the toe wipers travels lengthwise of the shoe in the operation of the wipers. The heel end is thus centralized laterally relatively to the paths of movement of the wipers. After the heel rest has engaged the shoe its forepart is clamped against the arm 62 by a toe rest E06 operated by means hereinafter described and the end gage 56 is withdrawn from operative position to permit the operation of the wipers.

In presenting each shoe the operator will haturally position its forepart so that, as far as he can readily observe, the shoe-engaging end of the arm 62 will be substantially midway between theopposite side edges of the shoe bottom. In order to relieve the operator of the necessity for exercising any particular care in this respect, and in order to insure that nothwithstanding such small variations as there may be in the positions of the toe ends of different shoes the toe wipers will nevertheless properly conform to the toe and will bear with substantially equal pressures on the opposite sides of the toe in the upwiping operation, the machine is further so con structed that the toe end of each shoe will adjust itself laterally to the wipers in response to pressure of the wipers on one side or the other of the toe. For this purpose the arm 62 and the toe rest H16, which constitute parts of a shoe support or holder, are so mounted as to permit them to swing with the shoe about an axis extending heightwise of the shoe in the vicinity of its heel end. The shoe support or holder includes a substantially vertical bar I88 (Figs. 1 and 2), pro-' vided at its upper and lower ends respectively with forwardly extending arms Ill) and H2. The upper arm H0 is provided with a stud H4 extending upwardly into an opening in a bracket i ltfast on the frame of the machine and is engaged by a ball bearing H8. In vertical'alinement with the stud I M is a stud I20 which is threaded in the frame of the machine and provides a bearing for the lower arm H2, the lower face of this arm resting on a ball thrust bearing e22 Extending lengthwise of the shoe from the bar we and curved laterally of the shoe (Figs. and 8) is an arm 12% terminating in a guide E26 for means hereinafter described for supporting the toe rest I06. The shoe-positioning arm 62 is supported on the upper forwardly extending arm Hi) of the bar I68 and is pivotally mounted for upward and downward swinging movements on a rod I28 supported in. ears on the arm H9. In its operative position the arm 62 is held against upward swinging movement by a latch I38 fast on a rod !32 mounted for turning movement in other ears on the arm i ii). A spring 134 mounted in the arm H0 and engaging a tail @36 of the latch H38 holds the latch normally in operative position, as shown in Fig. 1. By depressing an arm 538 fast on the rod I32 the latch 53:? may be withdrawn from operative position to permit the arm 62 to be swung upwardly away from the shoe while the wipers are over the shoe bottom. This may be done, for example, to provide more room for driving fastenings to fasten the upper in lasted position, if the upper is to be fastened in that manner, or in operating upon a welt shoe to provide more room for applying a wire binder about the toe. At one end the spring I34 engages the head of a pin I48 (Fig. mounted for limited movement in the arm I I0, one end of this pin bearing against a portion of the arm 62 below the rod I28. Accordingly, the spring-pressed pin I00 tends to swing the arm 62 upwardly, and may do so to some extent when the arm is released by the latch I30, the pin serving in any case to prevent the arm from being swung downwardly by gravity beyond the position determined by the latch.

From-the foregoing description it will be evident that the shoe support or holder, including the bar I08, the arm '62 and the toe rest I86, may swing with the shoe in one direction or the other about the axis determined by the studs 7 H4 and I20 in response to pressure of the toe wipers on one side or the other of the toe when the wipers are closed about the toe, so that the toe end of the shoe is permitted to adjust itself laterally to the wipers. It will also be evident that while the relation of this axis to the heel end of the shoe will vary somewhat for shoes of different sizes, it will, in any case, be located in the vicinity of the heel end of the shoe, and accordingly the heel rest will not interfere with such small movement as the shoe may receive in adjusting itself to the wipers. The heel end of the shoe being centralized laterally relatively to the paths of movement of the wipers as hereinbefore described, and the toe end thus centralizing itself relatively to the wipers, insurance is afforded that the wipers will properly fit the toe at the edge of the shoe bottom when advanced and closed a definite distance, the wipers, of course, being properly designed with reference to a sole pattern corresponding to the bottom of a shoe thus positioned. It will be understood that different wipers will be required respectively for right shoes and left shoes, as well as for shoes that differ materially in style or size. The shoe first adjusts itself to the wipers when the latter are closed about the toe below the edge of the shoe bottom prior to the upwiping operation, and may further adjust itself during the upwiping operation so that the pressures of the wipers against the upper at the opposite sides of the toe will be substantially equalized. Such further adjustment will occur, for example, if the shoe is shaped as illustrated in Fig. 11, one side of the toe having an outward inclination toward the edge of the shoe bottom and. the opposite side an inward inclination. I

It is desirable to prevent any lateral movement of the toe end of the shoe during the wiping of the margin of the upper inwardly over the insole,

so as to insure that the wipers will move inwardly equal distances from the opposite side edges of the shoe bottom. The machine is accordingly provided with means for locking the shoe holder against any further swinging movement when the wipers arrive substantially at the edge of the shoe bottom in the upwiping operation. For this purpose the guide IZ6, previously referred to as part of the arm I 24, has integral therewith short arms I42 and I44 (Figs. 1 and provided with a vertical pin I 46 on which is mounted a roll I 48. This roll lies in a slot I50 formed in a horizontal slide I52 movable in directions laterally of the shoe in a guideway formed in a block I54 which is fastened to an extension I56 of the plate 28 previously referred to as movable upwardly and downwardly with the toe wipers. Accordingly, any swinging movement of the shoe holder is accompanied by movement of the slide I52 along its guideway in the block I54. Mounted in a recess in the block below the slide I52 are two arms I58 (Fig. 3) arranged to swing about pins I60 fast in the block, the upper ends of these arms having eccentric faces I62 arranged to engage the lower face of the slide I52 and to lock the slide frictionally when the arms are swung toward each other. A spring I64 connected to the two arms tends thus to swing them toward each other. Normally, however, they are held far enough apart to permit movement of the slide I52 by a wedge member I66 which engages rolls I68 on the arms and is fastened on the frame of the machine. The wedge member is adjustable upwardly or downwardly along a guideway in the frame and is held in adjusted position by a screw I10 threaded in the frame and extending through a slot I12 in the wedge member. The member is so adjusted that as the two arms I58 are moved upwardly with the wipers in the upwiping operation they are permitted to be swung by the spring I64 into positions to lock the slide I52 and the shoe holder when the wipers arrive substantially at the edge of the shoe bottom. Formed on the top of the slide I52 is a lug I14 which is engaged on its opposite sides by two springs I16 mounted in the block I54. These springs insure against any excessive movement of the shoe holder when the machine is idle, and tend to return it to a central position after the lasting of each shoe. It will be understood that these are comparatively light springs, so that they do not oppose any considerable resistance to the swinging movement of the shoe holder in response to pressure of the wipers on one side or the other of the toe. I

The heel rest is swung into engagement with the shoe by depression of a treadle I18 fast on a rock shaft I80 at the base of the machine, this shaft having also fast thereon an arm I82 pivotally connected to an upwardly extending rod I84. The pivotal connection between the arm and the rod comprises a pin I86 arranged to enter any one of a plurality of holes I88 (Fig. 9) in the rod to vary the normal position of the heel rest for shoes which differ substantially in size. The rod I84 extends upwardly through a block I90, which is pivotally mounted on the end of a substantially horizontal arm I92 of the previously mentioned lever I02, and between the upper end of this block and a nut I94 on the rod is a spring I96. It will thus be seen that as the treadle I18 is depressed the lever I02 is swung to apply the heel rest to the shoe by downward movement of the rod I84, the spring I96 being yieldable in response to further movement of the treadle when the heel rest is in operative position. A flange I98 on the rod I84 serves by engagement with the lower end of the block I90 to determine the normal position of the rod relatively to the arm I92. The heel rest is swung away from the shoe by gravity acting on the arm I00 of the lever I02, and this lever serves to return the treadle I18, the movement of which is limited by engagement of a screw 200 thereon with a shoulder 202 on the frame. 7

Further movement of the treadle I18 after the heel rest has been applied to the shoe serves to actuate power means through the operation of which the toe rest I06'is forced against the shoe and locked, the heel rest is locked in operative position, and the toe end gage 58 is swung out of a guideway on the holder.

operative position. This power means comprises cooperating clutch members 204 and 206 (Fig. 1) having teeth on their opposed faces, the member 204 being part of a continuously driven pulley 206 mounted loosely on a shaft 2 I 0. The clutch member 206 is keyed to the shaft 2m to turn therewith and is movable also lengthwise thereof. A plurality of springs 2 l2 tend to force the member 206 into engagement with the member 204, but the member 206 is normally held out of such engagement by a clutch-controlling arm 2! (Fig. 9) in wedging engagement with one side of a lug 2l6 on the member 206. The arm 2M is fast on a rock shaft 2 l8 and is controlled by a spring 226 which normally holds it in operative position to disconnect the clutch members. Also fast on this rock shaft is an arm 222 engaged by an arm 224 of a bell-crank lever, and the other arm 225 of this bell-crank lever carries a bolt 226 the head of which is arranged to be engaged by a screw 228 carried by the treadle-operated arm 182. The lower end of the screw 228 is spaced initially far enough from the head of the bolt 226 to permit the required movement of the treadle I18 to apply the heel rest to the shoe, and as the treadle is further depressed the clutch-controlling arm 2 I4 is swung downwardly to cause the two clutch members 204 and 206 to engage each other. When the clutch is thus actuated the shaft 2H0 starts to turn and continues to turn through one revolution, whereupon the arm 214 acts to disconnect the clutch member 206 from the member 264, the treadle having been released by the operator.

The shaft 2! carries a gear wheel 230 in operating engagement with another gear wheel 232 which has twice as many teeth as the gear wheel 230 so that it makes only half a revolution before the shaft 2E0 comes to a stop. A pin 234 eccentrically mounted on the gear wheel 232 is connected by a link 236 to alever 236 fast on a rock shaft 240 mounted in bearings in the frame. The lever 236 has a forked end pivotally connected to two blocks 242 (Fig. 1) mounted to slide in horizontal guideways formed in opposite sides of a sleeve 244 movable upwardly or downwardly on a bar 246. Between a shoulder on this sleeve and a collar 246 fast on the bar 246 is a compression spring 250. At its upper end the bar 246 is guided in a bearing in the frame and carries a forked member 252 which supports a roll 254. The member 252 has a depending stem 256 mounted in a bore in the bar 246 and is held from turning by a pin 263 which lies in a slot in the bar. Supported on the roll 254 is the lower end of a toe post 260 slidingly movable upwardly and downwardly in the previously mentioned guide I26 of the shoe holder and held from turning by a key 262. The toe post 260 supports on its upper end a holder 264 for the toe rest H36, this holder having a depending stem 266 mounted in a bore in the post and held from turning by a pin 268 lying in a slot in the post. By means of a screw 210 the toe rest may be adjusted in directions lengthwise of the shoe relatively to its holder 264 along It will thus be seen that the toe rest I06 is forced upwardly to clamp the shoe against the arm 62 by upward swinging movement of the lever 238, the spring 250 being compressed more or less in this operation. At its lower end the toe post 260 is provided with a flange 212 (Fig. 8) for engagement with the roll 264-during any swinging movement which the shoe holder receives in the adjustment of the shoe to the wipers.

is of rectangular shape and is mounted in a guideway in the frame. Above the guideway the bar is provided with a plurality of ratchet teeth 214 arranged to be engaged by a pawl 216 (Figs. 1 and 4) to hold the toe rest l06 positively in shoesupporting position. The pawl is pivotally mounted on an upwardly extending arm of a lever 218 pivoted at 280 on the frame of the machine, this lever having a downwardly extending arm which carries a roll 232 controlled by a cam block 284 fast on a slide 286 (Fig. 9) which is vertically movable in a bore in the lower end portion of the bar 246, the cam block extending through a slot 286 in this portion of the bar. A pin 290 threaded in the slide 266 and extending through a slot 202 in the lower portion of the bar 246 is connected to a rod 294 extending upwardly through an opening in a lug 206 on the sleeve 244, and. between this lug and a washer 298 held by a pin on the upper end of the rod is a spring 300. Accordingly, as the sleeve 244 is moved upwardly along the bar 246 after the toe-rest has engaged the shoe the slide 286 is moved upward yieldingly by the sleeve through the spring 300 and causes the cam block 284 to swing the lever 210 in the direction to carry the pawl 216 into engagement with the ratchet teeth 214. The pawl then holds the toe rest H16 positively in any position to which it is moved in clamping the shoe against the arm 62, since the pressure of the roll 282 on the cam block 284 is not suflicient to cause any downward movement of the cam block against the resistance of the spring 300. In the return of the parts to starting positions the lug 266 engages a shoulder 302 on the rod 294 to impart downward movement to the cam block 284, the pawl 216 then being swung out of engagement with the ratchet teeth by a spring 304 connected to the tail of the pawl.

In order to guard against any downward swinging movement of the heel end of the shoe in response to pressure of the ends of the wipers on the bottom of the shoe in case, for example, the toe rest should be so adjusted as to be located substantially nearer the end of the toe than the ends of the wipers, the shoe support or holder is further provided with means for supporting the shoe and last in a location at the cone of the last. This supporting means comprises a rod 306 adjustably clamped in a holder 308 and having an enlarged head 3H] arranged to engage or support the top of the cone of the last in the location indicated in Fig. l. The holder 306 is adjustable by swinging movement in directions lengthwise of the shoe about the shank of a screw 3l2 (Fig. 10) whereby the holder is clamped in adjusted position on a vertical slide 3M movable in a guideway formed in a bracket 356 fast on the guide I26. A spring 3H) tends to move the slide 3E4 upwardly and holds it normally in a position determined by engagement of lugs 320 at its lower end with the bracket 3 l 6. When the operator presents the shoe to the machine he places the cone of the last against the head of the rod 306 and thereby forces the slide 3H4 downwardly to the position determined by the last and shoe when the shoe is in proper relation to the arm 62. Thereafter the slide is locked against any further downward movement by a pawl 322 (Fig-1) pivoted on the bracket BIG and arranged to engage ratchet teeth on the slide. For controlling this pawl there is provided a rod 324 pivotally connected to alug 326 on the member 262, this rod extending upwardly through an opening formed in a tail 328 of the pawl and carrying a spring 330 mounted between the tail of the pawl and a collar on the rod. Accordingly, as the member 252 is moved upwardly to force the toe rest against the shoe, the pawl 322 is forced yieldingly against the ratchet teeth of the slide 3I4 through the spring 338. In the return of the parts to starting positions an enlarged head at the upper end of the rod 324 acts on the tail of the pawl to swing the pawl away from the ratchet teeth.

The heel rest is locked in operative position by a pawl 332 (Figs. 1 and 8) in engagement with ratchet teeth formed on a bar 334 which is pivoted at one end to the arm I88 and is slidingly supported on the frame of the machine. The pawl 332 is fast on a pin 335 mounted to turn in an upwardly extending bifurcated arm of a lever 338 pivotally mounted between its ends on the frame, the lower arm of this lever engaging a wedge face 348 of a slide 342 vertically movable in a guideway in the frame. At its lower end the slide 34-2 is pivotally connected to a link 344 on which is slidingly mounted a sleeve 346 (Figs. 1 and 2) pivotally supported on the end of an arm 348 fast on the previously mentioned rock shaft 248. Between the sleeve 346 and a collar 358 fast on the link 344 is a compression spring 352. It will thus be seen that when the rock shaft 248 is turned in a clockwise direction (Fig. 2) by the previously described movement of the lever 238 (Fig. 9) the arm 348 acts through the spring 352 to impart upward movement to the slide 342, and the wedge face 348 of this slide acts to swing the lever 338 (Fig. 1) in a counterclockwise direction Prior to such movement of the lever 338 it is held by a spring 354 in a position in which the pawl 332 is out of engagement with the teeth of the bar 334, the pawl being controlled by a leaf spring 355 which is fast in the pin 336 and lies between two pins 358 on the lever 338. Accordingly, when the lever 338 is swung as above described, the pawl 332 is carried into abutting engagement with one of the ratchet teeth and then serves to lock the heel rest positively in operative position while forcing it still more firmly against the shoe. In the return of the parts to starting positions the sleeve 345 engages a nut 388 on the lower end of the link 344 and imparts downward movement to the slide 342, thus permitting the spring 354 to disconnect the pawl 332 from the bar 334 so that the heel rest may return to its idle position.

The lever 58 which carries the toe-end gage 55 is controlled by an arm 352 (Fig. 2) fast on the rock shaft 248. Pivotally connected to this arm is a link 334 which near its upper end is slidingly mounted in a sleeve 356 pivoted on the rear end of the lever 58. Between the upper end of this sleeve and a washer 358 held by a pin on the link 354 is a spring 318, and between the lower end of the sleeve and a collar 312 fast on the link is a spring 314. Pivotally mounted on the frame of the machine is a pawl 316 which is swung by a spring 318 into position to enter a notch 388 formed in a lug on the lever 58 to lock the lever with the toe-end gage in operative position when the lever is in position to permit the pawl thus to act. When the rock shaft 248 is turned in a clockwise direction (Fig. 2) as hereinbefore described, the collar 312 engages a tail 382 of the pawl and swings the pawl out of the notch 380, and the link 364 then acts through the spring 318 to swing the lever 58 to the position in which it is shown in Fig. 2, thus withdrawing the gage 56 from operative position. In the return of the parts of the machine to starting positions the lever 58 is swung reversely through the spring 314 to return the gage to operative position and the pawl 316 is released by the collar 312 to permit the spring 318 to return it into locking position in the notch 380.

In the operation of the machine, briefly summarized, the operator presents a shoe with the bottom of its forepart in contact with the three bosses 64 of the arm 62 and its toe-end face in contact with the end gage 55, placing the top of the cone of the last against the head 3I8 of the rod 388 and depressing this rod and its supporting slide 3I4 to the position determined by the shoe and last. He then depresses the treadle I18 to swing the heel rest into engagement with the heel end of the shoe and to cause it to centralize the heel end laterally. Further depression of the treadle serves to actuate the clutch 204, 286 to cause rotation of the shaft 2H] and the gear wheel 232. In this operation of the power-driven parts the heel rest is locked in operative position by the pawl 332, the toe rest I06 is forced up to clamp the shoe against the arm 62 and is locked in shoe-supporting position by the pawl 215, the support for the cone of the last is locked in supporting position by the pawl 322, and the toe-end gage 56 is swung upwardly out of operative position. When these operations have taken place the power-driven parts are brought to a stop automatically by disconnection of the cooperating clutch elements when the gear wheel 232 has made a half-revolution, the treadle I18 having been released by the operator. The operator then proceeds to last the toe of the shoe, advancing and closing the wipers about the toe by the hand lever 22 and raising them by the double-acting treadle 533 to wipe the upper upwardly to the edge of the insole. As the wipers are closed about the toe the shoe holder may be swung with the shoe in response to pressure of the wipers on one side or the other of the toe to permit the shoe to adjust itself to the wipers, and during the upwiping operation the shoe may further adjust itself in this manner so that the pressure of the wipers is substantially equalized at the opposite sides of the toe. When the wipers arrive substantially at the edge of the shoe bottom the shoe holder is locked against any further swinging movement by the action of the arms I58 on the slide I52. After further advancing and closing the wipers to wipe the margin of the upper inwardly over 'the insole the operator may, if desired, depress the latch I30 to release the arm 52 and may swing this arm upwardly out of the way to provide more room for fastening the upper in lasted position in case fastenings are to be driven for this purpose or, in operating on a welt shoe, to provide more room for applying a wire binder about the toe. If the arm 82 is thus swung upwardly, the wipers will be left in position over the shoe bottom until after the toe rest has been lowered, in order to prevent the toe rest and the shoe from being forced upwardly by the spring 250. After completing the lasting of the toe the operator again depresses the treadle I18 to actuate the clutch, whereupon the power driven-parts are returned to their starting positions, the toe-end gage being returned into proper position for use on the next shoe. Before presenting the next shoe the operator swings the arm 62 downwardly again into the position determined by the latch I38.
