  • This invention relates-to machines for use in the manufacture of boots and shoes for shaping the upper materials, and yis herein illustrated as applied to a machine of the type shown and described in Letters Patent N o. 1,700,970, granted on February 5, 1929 upon an application of William C. Baxtencomprising meansfor shaping ormolding the heel end portion of upper 'materials, oflI the last, over a heel. end form and over an insole to which the molded'heel end yof the upper is fastened while on the form. It is to beunderstood, however, that in various novel and useful aspects the invention is not limited to ina- ;i. chines of the type shown in said Letters Patent. v
  • Machines such as illustrated in the ⁇ abovementioned Letters Patent include in their organization a work support which is movable to carry the form and the shoe materials from a Work-receiving position into position to present the work to the upper-shaping means, and'inelude also a devicel for engaging the l upper in one or more jig holes provided therei in to position the upper in proper relation to the form.
  • a construction 'rangement such that the upper-positicnn1 i jigging device is operative only when the form is in its work-receiving position, the machine having mechanism for withdrawing said device from operative position prior to the movement of the form to carry the work to the upper-shaping means.
  • One advantage in this is that theconstruction is much simplied, as compared with an' organization in which the upper-positioning device and its controlling mechanism move with'the form as heretofore.
  • the invention further provides an upper-positioning device so constructed'and arranged as to occupy a position only over the eXtreme rear end of the form, thus affording the operatoran unobstructed viewl of the upper materials, includingwthe lining andthe flange of the counter, along the sides of the heel seat while he is arranging the materials in proper relation to the form.
  • the device herein shown serves also as a clamp member at the rear end of the heel seat, and is thus adapted to press down the inturned flange of a molded counter to position the counter initially in properI relation to the form.
  • this device comprises members arranged respectively to engage the insole and press it closely down upon the form and to engage the flange of the counter vand hold it in proper relation to the form until the upper materials are clamped about the form by the upper-shaping or molding means.
  • the above-mentioned counter-holding member is arranged, in the construction shown, to serve as a retarder in engagement with the inner face of the margin of the upper during the operation of the wipers, the member being so mounted and controlled as to be forced inwardly over the form against yieldingv resistance by the movementof the wipers.
  • This increases the frictional pressure ofthe wipers on the upper and assists in avoiding the formation of unduly prominent wrinkles in the margin of the upper about the rear end of the heel scat.
  • the machine herein shown has means for .pulling or tensioning ⁇ the upper forwardly about the form in the same general manner asdisclosed in Letters Patent No. 1,709,833, granted on April 23, 1929 upon another application of Villiam C. Baxter.
  • the invention.v further provides improvements in upper-tensioning means, including a simple and conveniently operable construction whereby different uppers are subjected to a pull of definite extent which, as herein illustrated, may follow a preliminary yielding pull, and a construction affording provision for convenient and certain adjustment of the pulling means in accordance with the cswing of a rightfor a left upper.

  • Pivoted on opposite sides of the holder 50 are links 66 the lower ends of which are provided with slots to receive pins 68 projecting from the member 60. Movement of the member 60 in the direction to withdraw the pins 62 from the holes 64 is limited by engagement of the member with ay iiange 70 formed on the plunger 52.
  • the spring 54 tends to force the plunger 52 downwardly, and that the limit'of such movement of the plunger is determined by engagement of the flange 70 of the plunger with the member 60 controlled b v the links 66.

  • the latch is arranged to engage the upper face of a lug 12() formed on the arm 78.
  • the return of the upper-positioning device to its idle position results normally from depression of the starting treadle 26 before the treadle has been moved far enough to start the machine in operation and thus to cause the form to receive its work-presenting movement toward the upper-shaping instrumentalities.

  • the member 144 is curved similarly to the contour of the toe and is provided with a shoulder 146 to support the inturned angularly shaped margin of the upper.
  • the member 144 thus supports the toe at a height determined by its adjustment on the arm 138, there being a screw-and.-slot connection between the member and the arm for purposes of heightwise adjustment, as illustrated in Fig. 2.
  • Thilo it is preferable that the member 144 be thus shaped to conform appro. ⁇ ;imately to the curvature of that portion of the molded toe which it engages, exact conformity in this respect is not essential, and it is accordingly practical to use the same member in oj'ierating upon uppers of different styles and sizes.
  • the strap 142 is arranged to support the toe end of the insole the heel end of which is positioned on the form by the pins 14.
  • the arm 138 is constantly under the influence of a spring 148 which is coiled about the axis 140 with one of its ends engaging a pin 150 on the holder 136 and its other end bearing against the arm. This spring tends to impart forward swinging movement to the arm 138 and the member 144, and when the parts are in idle position maintain the arm in engagement with a shoulder 152 on the holder 136.
  • the operator first positions an upper about the form 12 he swings the arm 138 rearwardly and mounts the molded toe on the member 144, whereupon the spring 148 acts to pull the upper with suliicient tension to hold it from slipping down over the form while the operator is mounting an insole on the form and is thereafter adjusting the upper materials in proper relation to the form.
  • the heel end of the upper materials have thus been posi ⁇ tioned in proper relation to the form, it is desirable to subject the upper to further tension, both in order to pull it tightly about the form before it is engaged by the molding means and also to insure against its displacement relatively to the form after the jigging device has been withdrawn.

  • the pawls 160 When the arm 154 is swung from its idle position to its other limit of movement, the pawls 160 are released by the plate 171 and permitted to engage the ratchet teeth, and are then operated by the movement ot the arm to impart positivelyl further pulling movement to the arm 138. lt will be evident that, whatever may be the position ci' the arm 138, the pawls will arrive in operative engagement with the ratchet teeth at the same point in the movement of the arm 154, and accordingly will act to impart upper-pulling movement of substantially the same extent to the arm 138 operating upon different uppers.
  • each upper a pull'oii iixed predetermined extent supplemental to the initial pull effected by the spring 148, so that insurance is aiiorded that each upper will be subjected to suificient tension.
  • the relation of the crank pin 158, which carries the pawls, to the other parts of the device is such that when the arm 154 is in upper-pulling position it is maintained in that position, in engagement with the stop 168, by the resistance of the upper, and when the arm is in idle position it is maintained in. engagement with the stop 166 by the action of springs 164 on the pawls 160. It will be understood that when the arm 154 is swung from operative position to idle position, the tails 170 oit the pawls are carried into engagement with the plate 171 which acts to release them trom the ratchet teeth.
  • the pivotal mounting '.134 of the holder 136 permit-s the upper-pulling device to be swung in either direction laterally of the form to position it in accordance with the lateral swing of a right or a left upper.

ERIC AUHOLMGREN, OIE LYNN, MASSACHUSETTS, ASSIGNOR TO UNITED SHOE MA- CHINERY CORPORATION, OF PATERSON, NEW' JERSEY, A CORPORATION OF NEW JERSEY. 1
Application filed .Tune 3D,
This invention relates-to machines for use in the manufacture of boots and shoes for shaping the upper materials, and yis herein illustrated as applied to a machine of the type shown and described in Letters Patent N o. 1,700,970, granted on February 5, 1929 upon an application of William C. Baxtencomprising meansfor shaping ormolding the heel end portion of upper 'materials, oflI the last, over a heel. end form and over an insole to which the molded'heel end yof the upper is fastened while on the form. It is to beunderstood, however, that in various novel and useful aspects the invention is not limited to ina- ;i. chines of the type shown in said Letters Patent. v
Machines such as illustrated in the` abovementioned Letters Patent include in their organization a work support which is movable to carry the form and the shoe materials from a Work-receiving position into position to present the work to the upper-shaping means, and'inelude also a devicel for engaging the l upper in one or more jig holes provided therei in to position the upper in proper relation to the form. By the present-invention, in one of its important aspects, there is provided a construction 'rangementsuch that the upper-positicnn1 i jigging device is operative only when the form is in its work-receiving position, the machine having mechanism for withdrawing said device from operative position prior to the movement of the form to carry the work to the upper-shaping means. One advantage in this is that theconstruction is much simplied, as compared with an' organization in which the upper-positioning device and its controlling mechanism move with'the form as heretofore. The invention further provides an upper-positioning device so constructed'and arranged as to occupy a position only over the eXtreme rear end of the form, thus affording the operatoran unobstructed viewl of the upper materials, includingwthe lining andthe flange of the counter, along the sides of the heel seat while he is arranging the materials in proper relation to the form. The device herein shown serves also as a clamp member at the rear end of the heel seat, and is thus adapted to press down the inturned flange of a molded counter to position the counter initially in properI relation to the form. l Y I ln accordance with. a further feature of the UPPER-SHAPING MACHINE.
1926. Serial No. 119,670.
invention, there is combined with a Workpositioning device which is operative, as above set forth, only when the form is in work-receiving position, another device for applying clamping pressure over the heel end'of the insole after the form has been moved to carry the'work to the upper-shaping means. In the construction shown this device comprises members arranged respectively to engage the insole and press it closely down upon the form and to engage the flange of the counter vand hold it in proper relation to the form until the upper materials are clamped about the form by the upper-shaping or molding means. It is-also an object of the invention to improve the results obtained in wiping the margin of the upper inwardly over the form, and to this end the above-mentioned counter-holding member is arranged, in the construction shown, to serve as a retarder in engagement with the inner face of the margin of the upper during the operation of the wipers, the member being so mounted and controlled as to be forced inwardly over the form against yieldingv resistance by the movementof the wipers. This increases the frictional pressure ofthe wipers on the upper and assists in avoiding the formation of unduly prominent wrinkles in the margin of the upper about the rear end of the heel scat.
For ,holding the upper during the workpresenting movement of the form in the relation to the form determined by the jigging means, and also to assist in shaping the upper about the form, the machine herein shown has means for .pulling or tensioning` the upper forwardly about the form in the same general manner asdisclosed in Letters Patent No. 1,709,833, granted on April 23, 1929 upon another application of Villiam C. Baxter. The invention.v further provides improvements in upper-tensioning means, including a simple and conveniently operable construction whereby different uppers are subjected to a pull of definite extent which, as herein illustrated, may follow a preliminary yielding pull, anda construction affording provision for convenient and certain adjustment of the pulling means in accordance with the cswing of a rightfor a left upper.
The above and other features of the invention, including mechanism of novel construction for applying u per-shaping pressure about the and. and ,si of the forni, .novel means for relieving the pressure of the wipers on the upper before the wipers are retracted, and various other novel details of construction and combinations of parts, will now be more particularly described with reference to the accompanying drawings and pointed out in the claims.

In its general organization, except as modied for purposes of the present invention, the machine herein shown is similar to the machine shown and described in theabove-men tioned Letters Patent No. 1.700.970. The ma chine includes an inner heel end form 12 pro vided with a pair of jig pins 14 arranged to project through jig holes formed in the heel end of an insole to position the insole in exact predetermined relation to the form. For shaping or molding the heel end portion of the upper materials over the form 12, there is provided a heel band 16 which clamps and shapes the upper about the end and the sides of the form, and wipers 18 which wipe the margin of the upper inwardly over fthe form and the insole. The form 12 is mounted, by means hereinafter described, on a work support comprising a carrier 20 which is pivoted at 22 on the base of the machine for swinging movement rearwardly to carry the form from a work-receiving position into position to present the work to the upper-shaping means. This movement of the work support is elfected by means of a cam, indicated diagrammatically at 23, on a cam shaft 24 controlled by a starting treadle 26, the connections between the cam and the carrier 20 comprising a lever 28 and a link 80.
The work support or carrier 20 is provided on its opposite sides with a pair of lugs 32 which, as the carrier receives its rearward movement to present the work to the uppershaping means, slide under a pair of hookshaped members 34 to lock the carrier in operative position, as illustrated in Fig. 10. In the construction herein shown the members 34 are so shaped as to lock the carrier positively against movement in either direction. so that the form 12 is held rigidly in operative position irrespective of any play that there may be in the bearings of the mechanism which imparts to the carrier its rearward movement. The members 34 are mounted to rock about a shaft 36. and in the construction shown are operated hy mechanism in depend ent of that which closes the heel band 16. thi s mechanism comprising a bell crank 3S one arm of which carries a roll engaged by a cam on the shaft 24 and the other arm of which is connected by a link to arms 42 which project downwardly from the members 34. A spring 44 connected to the bell crank 38 holds the members 34 initially in position to snap over the lugs 32 when the work support receives its rearward movement.
It will be understood that after the work support has been moved rear vfardly and locked by the members 34, the heel band 16 is closed to clamp and shape the upper materials about the end and the sides of the form. and thereafter the wipers 18 are operated to wipe kthe margin of the upper inwardly over the insole. lVhile the wipers remain at the end of their operative movement, tacks are driven., by means not. herein shown. to fasten the margin of the upper to the insole round the end and along tle sides of the heel seat. Thereafter the heel band is opened, the wipers are retracted and the form is returned to its starting position to permit the work to be removed.
For determining the proper relation of the upper to the form, there is proridei an upper-positioning or jigging device which is movable in a fixed path intov and out of operative relation to the form 121while the form is in its work-receiving position. This device comprises parts Ashowin in detail in Fig. 5, which are carried by an arm 46 pivoted at 48 on the frame of the machine in such manner as to swing in a plane perpendicular to the upwardly presented bottom face of the form. Slidably mounted 'in a holder 50 on the end of the arm 46 is a plunger 52 the lower end of which is enlarged to provide a seat for one end of a spring 54 within the holder. On the lower end of the plunger 52 is a presser foot 56 arranged to engage the shoe materials on the bottom face of the form. Pivotally mounted at 58 on the presser foot 56 is amember 60 provided with a lpair of curved jig pins 62 which are arranged to be proiected through holes 64 in the presser foot into position to enter jig holes provided in the margin of the upper, as illustrated in ,3. Pivoted on opposite sides of the holder 50 are links 66 the lower ends of which are provided with slots to receive pins 68 projecting from the member 60. Movement of the member 60 in the direction to withdraw the pins 62 from the holes 64 is limited by engagement of the member with ay iiange 70 formed on the plunger 52. It will be evident that, as the parts are thus constructed, the spring 54 tends to force the plunger 52 downwardly, and that the limit'of such movement of the plunger is determined by engagement of the flange 70 of the plunger with the member 60 controlled b v the links 66. When the arm 46 is swung downwardly, the presser foot 56 is moved into clampino` engagement with the shoe materialsr on the bottom face of the form. and then by continued movement of the arm against the resistance of the sprinar 54 the member 60 is swung bv the links 66 to proiect the pins 62 outwardlv into position for the upper to be hung thereon. In the reverse movement of the arm 46 the member 60 is first operated to withdraw the pins from the holes in the upper, and thereafter the presser foot 56 is lifted and the device is returned to its starting position in which it is shownv in Figs. i and 2. v
It will be observed that inthe construction, shown the upper-positioning or iigging device is so formed and arranged that itis positioned only over the extreme rear end of the form, so that in arranging in proper relation to the form the upper materials, including. for examplaa molded counter and a lining inside of the leatherfupper. the operators view of the materials lying along the opposite sides of the heel seat is unobstructed and he isaccordingly enabled to ydetermined readily whether they are properly positioned and, if necessary, to adjust ltion to receive the upper.
them in yproper relation to the form. The
presser foot 56 is thus arranged to bear on the work at the extreme rear end of the insole and is adapted to serve as a clamp member in engagement with the inturned flange of amolded counter vto position the counter counter positioning device from its idle position into operative position, there is provided a treadle 72 which is pivoted at74 (Fig. il) and is depressibleagainst the resistance of a return spring 75, the ltreadle having pivoted thereon at 76 an upwardly extending. arm 78. At its'upper end the arm v78 is provided with a laterally projecting lug 8O (F ig. 2) arranged to enter a slot 82 (Fig. 10)` formed in one side of averticallyl slidable bar 84 mounted in a casing 85 and to engage a hardened bearing block 86 which 1s fastened in the lower end of the slot S2.
A. spring 88 connected to the arm 78 holds the lug 8 0 in the slot 82 except when movec ment 1s imparted to the arm 78 to disconneet it from .the bar 84jin the manner heremafter described. For connecting the upper.
end of the bar 84 to the arm 46-there is provided a rod 90 the upper end of which is slidably mounted in lugs 92 and- 94 (Fig. 3) of a member 96 whiclris pivotally connected to an arm 98 integral with the arm 46, these two arms forming a bell crank. Faston the rod 90 is a collar l00which bears on the upper end of a spring 102 the lower f end of which is seated on the lug 92. It will thus be seenthat when the treadle 72 is depressed the bar 84 is moved downwarcly by the connecting arm 78, and that the arm 46 is thereby swung downwardly through `the connections described, the springrl02 yielding in the latter part of the movement of the treadle after the presser foot 56 has engaged thcrshoe materials and the pins 62 have been projected outwardly." into posi- The downward movement of the bar V84 is effected against the resistance ofa spring 104 which acts,
when permitted, to returnthe parts to their' p The limit. ofthe upward movement of the bar 84 is determinedv byv idle positions.
a lug 106 (Fig. l0) which is formed onthe bar jand is arranged to enter a slotv 108 in the casing 85 and to engage the casing at the upper end ofthe slot.
device has been moved into operative position by de ression of the treadle 72, it is retained t iat position by a latch 112 (Fig. 4) which is pivoted at 114 in the casing 85 and is controlled by a spring plunger 116 which holds it normally in a position determined by its engagement with a lug 118 on the casing. For the purpose in view, the latch is arranged to engage the upper face of a lug 12() formed on the arm 78. By reference to Fig. 10 it will be seen that when the bar 84 is in its uppermostposition, the lug 120 is over a laterally projecting lower end of the latch 112, and it will be understood that when the bar receives its downward movement, the lug engages the laterally projecting portion of the latch and swings the lat-ch to one side until it is permitted to snap over the upper face of the lug.
The return of the upper-positioning device to its idle position results normally from depression of the starting treadle 26 before the treadle has been moved far enough to start the machine in operation and thus to cause the form to receive its work-presenting movement toward the upper-shaping instrumentalities. For this purpose there is mounted to swing with the treadle 26 in fixed relation thereto an arm 122 which is provided with a roll 124 in engagement with another pivoted arm 126 having thereon a roll 128 for engaging the varm 78. By depression of the treadle 26 the arm 78 is thus swung forwardly and disconnected from the bar 84, where` upon this bar and the parts connected therewith are returned to their idle positions and the treadle 72 also is returned to idle position by its spring 75, The machine is further provided with means whereby the operator may, if desired, cause the upper and counter positioning device to be withdrawn from the work before depressing the starting treadle 26, this means comprising a knee lever 130 which in the construction shown is integral with the arm 126 and may be used to operate the latter so as to disconnect the arm 78 from the bar 84 independently of the operation of the starting treadle.
For holdingthe upperin the relation to the form determined by the upper-jigging means, and also to assist in shaping the heel end of t-he upper properly over the form, there is provided means for pulling or tensioning the upper forwardly about the form and for holding it under tension as the form is moved to carry the work to the upper-shaping or molding means. As illustrated in Figs. l1 and 8, there is secured to the front of the carrier 2O a bracket 132 upon which is pivotally mounted at 134 a holder 136 comprising a casing having mounted within it means for engaging the toe end of the upper and for applying thereto a forward pull. This means comprises an arm 138 which is pivoted at 140 in the holder 136 and has adjustably secured on its upper end portion a metal strap 142. The strap 142 is so shaped as to extend upwardly, then rearwardly, and then downwardly, and has fastened to its depending end a member 144 for engaging the toe of the upper. As herein illustrated, the machine is adapted for use in molding the heel ends of uppers the toe ends of which have been previously molded and have thereon inturned marginal portions shaped to conform substantially to the angle between the feather and the rib of a welt shoe insole, and the member 144 is so formed as to apply the pull to the inner face of the molded toe without impairing the molded shape. lt will be seen (Figs. 1 and 6) that the member 144 is curved similarly to the contour of the toe and is provided with a shoulder 146 to support the inturned angularly shaped margin of the upper. The member 144 thus supports the toe at a height determined by its adjustment on the arm 138, there being a screw-and.-slot connection between the member and the arm for purposes of heightwise adjustment, as illustrated in Fig. 2. Thilo it is preferable that the member 144 be thus shaped to conform appro.\;imately to the curvature of that portion of the molded toe which it engages, exact conformity in this respect is not essential, and it is accordingly practical to use the same member in oj'ierating upon uppers of different styles and sizes. lt will be further observed that the strap 142 is arranged to support the toe end of the insole the heel end of which is positioned on the form by the pins 14.
The arm 138 is constantly under the influence of a spring 148 which is coiled about the axis 140 with one of its ends engaging a pin 150 on the holder 136 and its other end bearing against the arm. This spring tends to impart forward swinging movement to the arm 138 and the member 144, and when the parts are in idle position maintain the arm in engagement with a shoulder 152 on the holder 136. lVhen the operator first positions an upper about the form 12 he swings the arm 138 rearwardly and mounts the molded toe on the member 144, whereupon the spring 148 acts to pull the upper with suliicient tension to hold it from slipping down over the form while the operator is mounting an insole on the form and is thereafter adjusting the upper materials in proper relation to the form. After the heel end of the upper materials have thus been posi` tioned in proper relation to the form, it is desirable to subject the upper to further tension, both in order to pull it tightly about the form before it is engaged by the molding means and also to insure against its displacement relatively to the form after the jigging device has been withdrawn. For this purpose there is provided, on the outside of the holder 136, a crank arm 154 fast on a rock shaft 156 and arranged to operate a crank pin 158 on which are mo-unted a pair of pawls 160 for engagingratchet teeth 162 provided on an arc-shaped portion of the arm 138. It will be seen that the end of one oit the pawls 160 is slightly in advance ot the end oi the other, so that one or the other of the pawls will be ready to act on the arm 138 in whatever position the arm may be. Springs 164, connected at their opposite ends respectively to the pawls and to the holder 136, tend to swing the pawls into engagement with the ratchet teeth or to hold them in such engagement. The crank arm 154 is movable through an arc of substantially 180O from an idle position, in which it is in engagement with a stop 166 on the holder 136 (Fig. 1), toa position determined by another stop 168 (Fig. 8).
When the arm 154 .is in idle position, tails 17 O on the pawls 160 are engaged by a fixed plate 171 in the casing 136, and the pawls are thus held out ot engagement with the ratchet teeth, as illustrated in Fig. 1. The arm 138 is then tree to be moved rearwardly as far as desired to engage it with the end ot' an upper, and after it has been thus engaged assumes, under the influence of the spring 148, a position which will vary in accordance with differences in the lengths of different uppers and diii'erences in the resistance of diilerent upper materials. When the arm 154 is swung from its idle position to its other limit of movement, the pawls 160 are released by the plate 171 and permitted to engage the ratchet teeth, and are then operated by the movement ot the arm to impart positivelyl further pulling movement to the arm 138. lt will be evident that, whatever may be the position ci' the arm 138, the pawls will arrive in operative engagement with the ratchet teeth at the same point in the movement of the arm 154, and accordingly will act to impart upper-pulling movement of substantially the same extent to the arm 138 operating upon different uppers. There is thus imparted to each upper a pull'oii iixed predetermined extent supplemental to the initial pull effected by the spring 148, so that insurance is aiiorded that each upper will be subjected to suificient tension. The relation of the crank pin 158, which carries the pawls, to the other parts of the device is such that when the arm 154 is in upper-pulling position it is maintained in that position, in engagement with the stop 168, by the resistance of the upper, and when the arm is in idle position it is maintained in. engagement with the stop 166 by the action of springs 164 on the pawls 160. It will be understood that whenthe arm 154 is swung from operative position to idle position, the tails 170 oit the pawls are carried into engagement with the plate 171 which acts to release them trom the ratchet teeth.
The pivotal mounting '.134 of the holder 136 permit-s the upper-pulling device to be swung in either direction laterally of the form to position it in accordance with the lateral swing of a right or a left upper. The arm 138 and its upper-engaging member 144 may thus be positioned for pulling movement substantially in the direction of the longitudinal median line of the orepart of the upper. This results more nearly in equalization of the strains applied along the opposite sides of the upper than if the pull were applied inthe direction of the longitudinal median line of the heel end form, and also avoids danger of lateral displacement of the back seam of the upper relatively to the form by the torce of the pull. To maintain the holder 136 in adjusted position, the holder is provided with a springcontrolled latch 172 arranged to engage teeth 173 formed on the front end` ot the bracket 132. To determine symmetrically opposite positions of adjustment of the holder 136 `for right and left shoes of the same size and style, there are formed` in the4 bracket 132 a series of holes 174 in which pins 175 may be placed in selected positions to serve as stops to limit vmovements of the holder in opposite directions.
After the form with the shoe materials has been moved rearwardly into position tor the molding operation, clamping pressure is automatically applied over the form to the insole and to the rear end ot the inturned flange of the molded counter inserted between the upper andthe lining. For this purpose therel is provided a clamping device comprising a holder 176 which is carried by a vertically movable arm 177 (Fig. pivoted at 178 on a bracket on the trame of the machine. On its lower face the holder 176 carries a pair ot spring lingers 180 (F ig. l9) arranged to bear on the insole between the opposite rear end portions'of the insole rib. Mounted in the holder 176 is a horizontally movable slide 182 which has a pair of downwardly extending fingers .184 arranged to hear on the flange ot the counter at the rear end of the heel seat and spaced apart in such manner as to clear the rearmost jig pin 14 when the slide 182is moved forwardly in a manner to be described. At its front end the slide 182 is connected to lever 186 which is fast on a rockl shaft 188 mounted in spaced bearings on the top of the arm 177, and act-- ing upon thisrock shaft is a torsion spring 160 which tends to impart rearward movementto the slide 182. A s the parts are initially positioned, the lower. end ot the lever 186 is held by the spring 190 in engagement with a part of the holder 176, as shown in Fig. 8, andthe fingers 184 are thus in position`to engage the flange of the counter when the arm 177 is swung downwardly.' For swinging the arm 177 there is provided a linlr 192 which connects the arm to one end of a lll lever 194 (Fig. 1), this lever being pivoted at its opposite end and carrying a roll 196 engaged by a cam indicated diagra1nmatically by dot-anddash lines at 198. The connections between the link 192 and the lever 194 include a spring 200 which may yield in response to Acontinued movement of the lever after the clamping device has been carried into engagement with the work.
After the clamping pressure has been ap plied to the insole and to the tlangevoi' the counter as above described, the holder 176 remains in operative position until atter the margin ofthe upper has been wiped inwardly over the form and has been fastened to the insole by the tacking mechanism. As the wipers 18 are advanced and closed to wipe the upper over the form, the slide 182 and its fingers 184 are forced inwardly against the resistance of the spring 190 by the pressure of the margin of the upper against the lingers. In this operation the fingers 184s perform the additional useful tunction of a retarder by holding the margin et the upper at the rear end-of the form upstanding against the edges of the wipers, thus increasing the frictional pressure of the wipers on the upper and at the same time assisting in preventing the upper from wrinkling unduly at any point about the rear end et the heel seat as its margin is gathered inwardly by the wipers. The cam 198 is preferably so shaped as to relieve somewhat the downward pressure of the lingers 184.- upon the heel seat prior to the inward movement of the wipers, and thus 'facilitate the sliding movement of the lingers over the shoe materials.
In order to prevent breakage ot the parts in the operation of the tacking mechanism (not shown) in case the machine is operated idly without any wipers therein, there is provided additional automatic means which is operative under those conditions to retract the slide 182. For this purpose there is tast on the rock shaft 188 an upwardly extending finger 202 having a wedge tace arranged to be engaged by a pin 2041 (Fig. 1) carried by a downwardly movable part of the tacker mechanism which operates in the manner fully described in Letters Patent No. 1,7 00,970.
The form 12 is fast on the upper end of a rod 206 which is slidably mounted in a bearing in the upper end of the carrier 20 and is also slidable at its lower end in an opening formed in a member 208 threaded in the lower end of a sleeve 210 which is also slidable in the carrier 20. Adjustably threaded on the rod 20G is a sleeve 212 the lower end of which is provided with a flange 214 within an opening in the upper end of the sleeve 210. Between the member 208 and av washer 216 which engages the lower end of the sleeve 212 is a spring 218. The spring thus provides a yielding connection between the member 208 and the rod 209 when upward movement is imparted to the sleeve 2li), such upward movement beingl ell'ected, as de scribed in the last-mentioned Letters Patent, for the purpose of moving the torni l2 up toward the wipers and thus increasingr the pressure oi the wipers on the margin ol the upper in time relation to the wiping operation.
For effecting such upward movement oll the sleeve 210 the machine is provided, as heretofore. with a toggle 22() comprising a pair ot links one ot which is connected to the sleeve 210 and the other pivoted at 22 on the base of the machine. the upper link ot the toggle being connected by a link 222 to a lever 224C which is pivoted at on the trame and carries a roll 228 arranged to he engaged by a periiheral cam 230 on the cam shaft 24:. Initially the toggle 220 is broken toward the right (Fig. 1) with the form l2 in a lowered position determined by a stop nut 282 threaded on a rod 22M which is pivoted on the lower toggle link, this nut beine' arranged to engage the carrier 20. as illu:=v 'trated in Fig. 1, to limit the breaking ot the toggle. When the carrier 20 is swun lo carry the form into operative position. V(he roll 228 is moved into position to be operated by its cam 230 at the proper time in the cycle.y so as to straighten the toggle and thus lo impart upward moven'ient yieldingly to the term.
The machine herein shown is further constructed to lower the ttorm 12 and the ,shoe materials betere the wipers are retracted from over the form, so as to prevent the wipers from dragging on the. upper in their outward movement. rlhis result accomplished by an additional rise on the cam 29,0 which acts to break the toggle 220 toward the left, as indicated in Fig. 10. lllhcn this action occurs the term is moved positivelv downward by reason ot the em m; ;ement ot the end oi a screw`230 on the sleeve 210 with the upper tace ot the fiange 2l-l ot the sleeve 212. Such lowering of the form takes place after the heel band 10 has bren opened to rc lease its pressure on the upper. .fitter the form has been started down ardly by the action of' the cam, it may continue its downward movement by gravity 'lar enough to carry the roll 228 away trom the cam. as illustrated in Fig. 10. such movement bein.;r limited by a stop screw 288 which is mounted in a lug projecting from the lever 221 and is arranged to engage a part of the base 240 of the machine. Preferably, as shown. the -form will thus be moved downwardl)7 to a position lower than its initial position. or its position in the overwiping operation, to insure proper clearance between the upper a nd the wipers. lllhen the carrier 20 receives its` ioiwrard movement, in the return ot the parl-s to starting position, the screw 238, by its llltl llfi engagement with the base l240,fholds the lever 224 from swinging, so that the lever acts to break the toggle 220-back to its original position in response "tothe forward movement g of the carrier.:
.t-.he end'fand rsides of the form comprises an inner port-ion ,of leather or other suitable f material which is mounted upon supports or holders somprising an end block 242, side `members 244,1and links 246 and 248 connect- Foriclosing said blocks and side members. ingthe band about the form there is provided a sliding:crosshead 250 which acts directly through Ia spring 252 upon the end block 242 at the intermediate portion of the band, and actson the side members 244 through links 254 andyieldingly controlled toggles 256,'subs`tantially.asshown and described kin Letters .Patent No. 1,700,970.
- Pressure is'further applied `te the links 248,
at what maybe termed'y the rear cornersaof the band, by novel mechanism comprising yielding linksoperated'by theI cross-head 250.
Each of `these links 'comprises a member 258l `swiveled at one endin rabearing in the cor- 'respondingband link 248and provided with a slideway 260in=which ismounted another member 262 which is connected Ito the crosshead250, the member 262having fast thereon plates 263 `overlapping'the opposite sides 1 ofthe member 258i 'Mounted in sockets in lthe links 248 vafter pressure .has'begun to bev` applied through the spring 252 to the block 242 at the intermediate portion ofthe band. It will be further seen that the pressures 'applied'to the'links 24S-are; in forward direc-v tions substantially lengthwise of the form 12, or in direct-ions more nearlyfparallelto the lengthwise dimension-of the'form than are lines drawn perpendicular'to the upper-en- 4face vof the corner portions `of the There is thus aforwardwpulling ac band.

In the operationA of the machine,,brietly summarized, the operator places the' heel en d of the upper vmaterials.about `the form 12,.
swings the upper-'pulling arm 138rearwardy ly and engages the member 144 with the prey to counteract ythe yforward 'pressure .off
vious'ly molded toe, and then releases the arm to cause the upper to be subjected vto the comparatively light tension of the spring 148, which is suflicient to 'hold the heel end of the upper from slippingV downwardly over the form. The operator then places an insole upon the form in the position determined by the pins 14 and with its toe end resting upon f the upper-pulling device,y and thereafter ad justs the counter and thelining relatively to the form and the insole. By depression of the treadle 7 2 the lupper-positioning and counter-clamping vdevice isthen swung downwardly into operative position-over the rear end of the form, with the presser foot 56 engaging the flange of the counter andthe pins62 projecting-rearwardly through the holes in the presser foot', the latch 112 automatically'locking-the device in operative position by engagingthe lug 120 of the arm 78, as illustrated in Fig. 4. "The operator next hangs the upper upon the jig'pins 62, slips the heel end ofthe upper downwardly about the form enough tov straighten it relatively tothe jig'pins, `and thereafter swings the crank arm 154 from-its idle position to its operative position( Fig. 8) to subject the up- A per to increased forward tension.
to start the: operation of the machine, the treadle acting in the first part of itsmovement to, disconnect the arm 78* from the latch 112 and from the bar 84' and thus to release the upper-jigging and counter-clamping device,
which is thereuponfwithdrawn from the'work andreturned to its idle position. `During the rearward movement'of the'formv to carry the work toward the molding means the forward Vtension applied tothe kupper-b the pulling 4device' serves to hold the upper fiom displacement relatively to the'form. Assoon as vthe form has arrived at thelimitof its rearward movement the device for clamping the insole andthe' flange of thecounter is swung downwardly into `operative position, vand then the .heel band 16'` is operated to clamp the upper ymaterials about the'end and the sides ofthe form. The wipers 18 are then advanced and closed to wipe Vthe margin ofthe upper inwardly over the flange of the counter and over the insole, and during this operation the counter-clamping fingers-184 act as wa retarder in engagement with-the margin of the yupper while being forced inwardly over the heel seat 'by thepressure of the wipers, the-cam 168. having relaxed the downward pressure of the lingers 184 uupon the heelseat. It is contemplated that the wipers will receive only one inward wiping movement, and near the 'end of this movement the toggle y220 is straightened tovforce the form up toward the wipers and thus to increase the molding pres,-4
sure of the wipers on the upper. While the wipers are at the end of their wiping movement the tacks are driven to fasten the upper and the tlang'e of the counter to the insole. Thereafter the parts of the machine are returned to starting positions, the heel band being first opened, and then the toggle 220 moved to the position illustrated in Fig. 10 to lower the form before the wipers are retracted. After the carrier 2O has been swung forwardly with the shoe materials, the operator swings the crank arm 154 of the upper-pulling device to its idle position, disengages the toe of the upper from the member 144 and then removes the shoe materials from the form.
