PLATFORM COVER TURNING MACHINE Filed June 25, 1962 '7 Sheets-Sheet 7 United States Patent This invention relates to machines for use in the manufacture of shoes, and is herein illustrated as embodied in a machine for turning a platform cover over a platform or midsole of a platform shoe of the type variously referred to as California, slip-lasted or force-lasted.

In the manufacture of shoes of this type an upper, an insole or sock lining, and av strip of flexible material known as a platform cover or wrapper, are assembled together oif the last, usually by stitching. A precemented midsole or platform is thereafter attached to the sock lining, a last inserted into the shoe to shape the shoe, and the cover or wrapper is laid over and secured to the marginal portion of the platform to cover its edge. An outsole is subsequently cement attached to the platform, which sometimes has an integral wedge heel, to complete the shoe.

The cover or wrapper usually hugs the upper rather intimately and, before it can be laid over the platform by the lasting instrumentalities of the lasting machine, -must first be turned away from the upper. The operation of turning the cover is often performed after a last has been forced into the shoe. In prior cover turning machines the turning is efected by grippers which engage the margin of the cover at several points and pull it to turn it away from the upper either by movement of the grippers wmle the shoe is held stationary, or by movement of the shoe relative to the stationary grippers. In either case, such pulling action, unless carefully controlled,v

subjects the cover strip to stresses which may damage it or even rip it away from the upper and sock lining.

It is an object of the invention to provide a machine for turning the platform cover at the forepart of a shoe after a platform sole has been attached to its sock lining but before insertion of a last, wherein the risks pointed out above are eliminated.

To this end, the machine disclosed herein comprises a form engageable in the interior of the forepart of a shoe to support the shoe while a platform sole is attached to its sock lining, a gage movable into engagement with the toe end of the shoe to permit an operator to register the platform sole with relation to the sock lining, gripper means engageable with the free margin of a platform cover at the toe end of the shoe, a fixed abutment engageable with the platform sole of the shoe when the shoe is moved oil the form, wipers engageable between the cover and the upper, and means to impart to the gripper means and the wipers movement in a direction to move the shoe off the form and to cause the wipers to move relative to the shoe after engagement of the platform sole with the ixed abutment to turn to cover away from the upper into a plane substantially normal to the plane of the platform sole.

Preferably, and as herein illustrated, the form is constructed to be expanded laterally within the forepart of the shoe so as to maintain the sock lining taut while a platform sole is attached, and the invention provides means effective to cause'the form to be expanded and concomitantly therewith to move the gripper means and the wipers into position to engage the platform cover and the upper, respectively, and additional means effective to cause the form to be contracted after the attachment of the platform sole and concomitantly therewith to render effective the means mentioned above which lhdfi Patented Jan. A26, 1965 impart to the gripper means and wipers movement in a direction iirst to move the shoe off the form and thereafter to cause the wipers to move relative to the shoe while the cover is held gripped by the gripper means to effect the turning of the cover.

These and other novel features of the invention will appear more clearly from the detailed description which follows and will be more particularly pointed out in the claims.

FIG. 2 is a View infront elevation of the machine shown in FIG. 1;

FIG. 3 is a plan View of the machine head;

FIG. 4 is a detail perspective view of an equalizing mechanism for controlling the tensioning action of gripper members engageable with a platform cover of a shoe mounted in the machine;

FIG. 5 is a plan view, on an enlarged scale and partly broken away, of an expansible form engageable in the interior of the forepart of a shoe to be operated upon;

FIG. 6 is a view in left side elevation, partly in section and on the same scale, of the form shown in FIG. 5;

and

FIG. 7 to lO, inclusive, are views in left side elevation illustrating the positions of the operating instrumentalities of the machine iat various stages of a cover turning operation.

The shoe S to be operated upon in the illustrated machine comprises an upper U (FIGS. 1 and 7 to l0), to the lower margin of which is attached a sock lining I., and a platform cover strip C which, after attachment of a midsole or platform I to the sock lining and insertion of a last, is laid over and secured to the marginal portion of the platform in a cover lasting machine to cover the wall or edge face of the platform sole prior to attachment of an outsole to complete the shoe. Before it can be thus laid and secured to the platform, the cover which as shown in FIGS. '7, 8 and 9 occupies an upstanding position parallel to and in close proximity to the upper, must be turned substantially away from the upper to permit the lasting instrumentalities to tension and wipe it inwardly over the platform.

To effect the turning of the platform cover C in the illustnated machine, the operator slips an unlasted shoe over a jack or form, identified generally by the reference character 2t? (FIGS. l, 2, 3, 5, 6 and 9) and comprising an arm 22 which, as viewed from the front of the machine, that is, at the right of FIG. l, extends upwardly and rearwardly from a base plate 26 and, as shown in FIGS. 3 and 5, terminates in an enlarged, flat and wedge-shaped portion 24 engaged by the forepart of the sock lining of the shoe. The base plate 26 is bolted yto the top of a post or frame 28 fixed to a casing 3@ rising from the base 32 of the machine. The shoe form or jack 29 also comprises a pair of blocks 34 which, as best shown in FIGS. 3 and 5, are shaped to correspondsubstantially to the two halves of a divided, laterally expansible shoe form or last and which, when expanded in a manner shortly to be described, stretch the jacked shoe so as to facilitate :the attachment of a platform sole to the sock lining. Each block 34 is pivotally secured by a pin 36 to the upper rearwardly extending arm of a substantially U-shaped member 3S which is hingedly mounted for lateral swingingV movement relative to the arm 22 on a bolt or pin itl projecting upwardly from the base plate 26, the opposite sides of the arm 22 being recessed, as shown at 41 in FIG. 6, to iaccommodate the two members 3S. As shown in FIG. 5, each block 34 is recessed o-r rabbeted at 42 to provide clearance for movement of expansion and contraction of the blocks relative to the tapered rear portion 24 of the snaar/ro es d each block 34 iabout its pivotal connection to the member 3S to conform to the contour of the forepart of the shoe after the blocks have reached the limit of lateral expansion within the shoe.

For actuating the members 38 to cause movement ot expansion of the blocks 311, the following arrangement is provided. Extending downwardly from the lower, rearwardlyextend-ing arm of each member 3d is ia pin 44 which is engaged by a roll 46 carried by a pin 4S mounted in the larms of the bifurcated upper end portion of a lever Si) (FiG. 2) pivoted at 52 on a bracket 54 which is fast on the post 2S. The lower, bifurcated end of each lever 50 also carries a roll 56. The rolls 56 engage the opposite sides ofa cam block 58 mounted for heightwise sliding movement on a bar 613 fixed at its opposite ends to cross members 62, 64 between the spaced uprights of the post 28. The Ablock 58 is connected by a rod 66 to a treadle 63 (FG. 1) p'ivoted at 69 on the base 32 of the machine. To the rod 66 is attached one end of a spring 71B, the other end of which is anchored to the casing 3, the arrangement being such that the spring maintains the treadle normally in a position intermediate of its upper and lower limits of movement for a purpose which will be explained below.

In the rest position of the machine the rolls 56 on the lower ends of the levers 5@ are in engagement with the opposite sides of the upper, wide portion of the cam block 58, whereby the levers are biased in a direction such that the rolls 46 on their upper ends press :against the pins 44 to maintain the members 38 close together, as shown in FIG. 3, against 4the tension of associated springs 72 whichrtend to cause them to swing away from each other. The spring 72 associated with each member 3S is attached at one of its ends to a pin 73 projecting from the lower, rearwardly extending arm of the member 4and at its opposite end to a pin '74 projecting downwardly from the base plate 26.

To the treadle 68 is also connected the lower section 75 of a two-part rod 76 (FIG. l). The upper end of the rod section 75 is threaded into a bifurcated block 7S, between the arms of which is mounted a pin 88 to which is connected one end of a link 82, the other end of which is pivoted at S3 to the lower end of an larm 84 depending from Ia bracket 36 fixed to the cross member 64. Also mounted on the pin Sti is `a bifurcated block $8 into which is threaded the lower end of the upper section 9% of the two-part treadle rod 76.V The upper end of the rod section 90 is connected to a bell crank lever 92 comprising a rearwardly extending arm 94 and a forwardly extending, longer arm 96. rl`he arm 94 is pivoted on a pin 97 mounted in rearwardly extending parallel `arms 98 of a carrier 1d@ having downwardly extending parallel arms 161 pivoted at their lower ends on a transverse shaft 102 supported ilihe bracket 86 and upwardly extending parallel arms Between the upper ends of the spaced parallel arms 163 of the carrier 10@ there is provided a block 164 (FiGS. 1, 3 and 7-10) formed with forwardly projecting lingers 106 arranged to contact the outer face of the platform wrapper at opposite sides of the tip of the shoe, when the carrier is caused to swing into operative position in a manner to be described shortly, and to cooperate with complemental fingers 168 adapted :to engage the inner face of the cover. The fingers w8 are integral with a pair of parallel arms pivoted at their forward ends on a pin or bolt 112 extending through the block 1de. The arms 11E) are connected by universal joints 114, rods 116 and universal joints 11S to the opposite ends of a whiiiietree 121i (FlGS. 3 and 4) mounted for rocking movement about a bolt 121 extending into the arm 96 of the bell crank lever 92. To the upper surface of the arm 96 is secured by a screw 12,2 a T-shaped leaf spring member 123, the cross bar of which overlies the whiiiietree 12@ and tends to maintain it in condition of equilibrium. This arrangement permits equalizing the tension exerted on the platform cover by the gripper lingers 193 at the opposite sides of the toe end of the shoe.

On each end of `the bolt 112 is mounted for rocking movement about the bolt a cam member s (FiGS. 1, 3 and 7-10) `to which is secured one end of an arm 126 consisting of a str-ip of flexible metal, such as spring steel. To the other end of each arm 12d is xed a blade or wiper 128 which, when the carrier 1&5 is swung in one direction, is moved into a position between the piatto-rm cover C and the upper U a. the side of the shoe S and which during the reverse swinging movement of the carrier, is moved in a direction to turn the cover from the position shown in FIG. 7 to that shown in FIG. l0. To a pin 13d projecting from each cam member 124 is attached one end of a spring 132, the other end of which is attached to the underside of the adjacent gripper arm 11d. in the rest position of the machine the springs 132 maintain the cover turning wipers 12S and the cam members 12 in the positions shown in PiG. 1 in which each cam member is in engagement with a roll 134 (FIGS. l, 3, 9 and 1G) mounted on the forwardly projecting portion of a bracket 136 secured to each of a pair of spaced uprights 13S mounted at their lower ends on the shaft 192 and joined together at their upper ends by a cross member 14d. The structure formed by the uprights 138 and the cross member 14? is connected by members 142 lto the opposite sides oi a bracket or frame 144 secured lto the cross member 52.

The assembly described above is under the iniiuence of a spring 146 (FGS. l, 9 and 10) attached at one end to a pin 143 projecting from the carrier 161i and at its opposite end to a pin 15G projecting from the bar dll, the said spring tending to cause the carrier 109 to swing clockwise from `the position shown in PEG. 1 to that shown in FiG. 7. T-'he assembly is held in its retracted position sho-wn in FlG. 1, against the tension of the spring 146, by engagement of a detent 152 (FIG. l) fixed between the rearwardly extending arms 93 of the carrier i with a pawl 154 fast on a rockshait 156 mounted in the uprights 138. Also fast on the shaft 156 is one end of a link 153, the other end of which is pivota-lly connected to 4the lower end of a rod 166 extending through a plate or bracket 162 fixed to the cross member 140. The upper end of the rod 166 is provided with a knob 164 between `which and the plate 162 is interposed a spring 1&6 surrounding the upper end portion of the rod lett.

The operation of the machine thus far escribed is as follows, The operator mounts the orep-art of an un- -lasted shoe S in inverted position on the jack or form 20 (FlG. 1) comprising the arm 22 with its flat wedge-shaped portion 24 and the blocks 38, which at this time are in the closed or contracted positions. He then presses the knob 164 and, the rod 160 being depressed, the link 158 is .caused :to swing clockwise and the shaft 156 is rocked in the same direction, disengaging the pawl 154` from the detent 152 and releasing the assembly comprising the carrie-r 169, on which are mounted the gripper fingers 196, 1118 and the cover turn-ing wipers 12S, to the .action of the spring 146 which causes it to swing in a clockwise direction from the position shown in FIG. 1 to that shown in FIG. 7. When the knob 164i is released, the rod 160 is .returned to its initial position by the spring 165 and causes the link 153 to swing in counterclockwise direction to locate the pawl 15d in position to `be engaged by the detent 152 to lock the carrier when lthe tre-adle 63 is released at the end of a cover turning operation. Movement of the link 15S in that direction is limited by a stop pin 167 (FlG. 1) projecting from one of the bars or uprights 133.

As the assembly' is thus unlocked, the treadle 63 which, las previously noted, is held by the spring 7@ in an intermediate position when the assembly is locked, is raised by the spring. As the treadle rod 66 moves upward, the

cam block 58 move upward along the slide bar dil and the opposite inclined sides 58a of its lower portion (see FIG. 2) are engaged by the rolls 5o on the lower ends of `the levers 50, which are thereby caused vto swi-ng oppositely :outward and away from the pins 44 depending from the lower arms of the members 33, so that these members and the blocks 54 carried by them may be swung by the springs 72 in a direction to expand laterally within the forepart of the shoe and support it iirmly while Ithe operatorattaches a platform to the sock lining.

When the carrier 109 swings clockwise, a toe gage lS (FIGS..1 and 7 to l0) is moved into engagement with the .toe end of the shoe, the gage projecting somewhat above the level of the sock lining L to enable the operator to locate a platform P on the sock lining. The toe gage 168 forms one arm of an L-shaped lever 171i, the other arm 172 of which terminates in a bifurcated block 174 which is fulcrumed on a pin 176 mounted in a lug 177 projecting from the block 164 between the arms 1&3 of the carrier 10G. The lever 17@ is normally held in the position shown in FIG. 1 by a tension spring 173 attached at one end to the lever arm 172 and at its opposite end to lthe pin 14S which projects from the carrier. As the carrier 1mi swings from the position shown in FlG. 1 to that shown in FIGS. 7 and S, the undersurface of the lever `arm 172, somewhat to the left of the rounded lower edge of the block 174, is engaged by a roll 189, and the lever 17d is swung clockwise about the pin 176, against the tension of the spring 178, to loca e the gage in operiative position. The -roll 13@ is carried by a pin 182. mounted in the bifurcated rear end portion of'a block 184 pivoted at its forward end on a pin 186 mounted in the upwardly extending arms of the bracket 14d. The block 184 is maintained by a spring 13S, which is connected at one end to the 'block and vat its other end to the bracket 1M, against the upper end of adjusting orew 1% threaded through a boss 192 of the bracket 144. By adjustment of the screw 19t? the level of the rearward end of the block 184 may be varied so as to vary the extent of clockwise swinging movement of the lever 17? to locate the toe gage los in different operative positions according to differences in the sizes of shoes mounted -on the form or jack 2%. A nut 19d locks the screw 19? in the adjusted position.

Movement of the carrier 1Gb to the position shown in PEG. 7 moves the fixed upper gripper fingers lilo projecting from the block HB4 disposed between the upper ends of the rarms 1i3 of the carrier into engagement with the outer face of the cover strip C, while the lower lingers 198 formed integral with the pivoted arms 11o are moved into a position between the cover and the upper. A-iso, as the carrier 1% is unlatched and the cam members 124 which carry lthe lcover turning wipers 128 .are moved out of engagement with the .rolls 134 (FlG. 1), the springs 1.32, which are attached to the pins 136 on the cam members, swing the cam members in a clockwise direction to locate the wipers in the substantially horizontal position shown in FiG. 7.

The operating instrumentalities of the machine occupying the positions shown on FIG. 7 and the forepart of the s'noe being stretched on the form Ztl, the operator spots and ,attaches by hand to the sock lining L a precemented platform P, utilizing the gage 158 to register the platform correctly with relation to the sock lining. He next depresses the treadle 68. During the first portion of the downward movement of the treadle, the treadle rod 76 swings the lever 92 about its fulcrum 97 in a clockwise direction to rock the gripper amis 110 counterclockwise, iirst to the position shown in FIG. 7, to bring the gripper ingers 108 into engagement with the free margin of the cover C at the tip of the shoe, and then to the position shown in FG. 8. As the :arms 110 rock in that direction, they impart, through the pins 130 carried by the cams 124, movement in the same direction to the cams to move the wiper blades 128 from their horizontal d position shown yin FIG. 7 to that shown in FIG. 8, where they engage the sides of the shoe, the spring arms 126 to which the blades are secured yielding laterally to enable the blades to accommodate themselves to the width of the shoe.

When the gripper ngers 108 reach the position shown in FIG. 8, with the margin of the cover C at the tip of the shoe engaged between them and the fixed upper gripper fingers 166, the gripper arms 110 and their ingers 1118 become rigid with the carrier 100. Thereafter, as the treadle is depressed further, the assembly comprising the carrier 16@ and the gripper members is rocked as a unit,

coun'terclockwise about the shaft 102, from the position shown in FIG. 8 to that shown in FIG. 9, overcoming the force of the spring 146 which tends to urge the carrierV to swing clockwise.

As the treadle is depressed, the treadle rod 66 (FIG. 1) moves the block 5S downward to the position shown in FIG. 2, where the sides of its upper, wider portion are engaged by the rolls Se on the'lower ends of the levers Si), causing the levers to swing oppositely inward to bring the rolls 48 at their upper ends into engagement with the pins 44 carried by the members 3S, whereby these members are caused to turn about their pivots d@ (FIG. 1) toward each other to move the blocks 34 from their expanded position shown in FlG. 5 to theirorginal contracted position, so as to release the shoe. s

When the carrier litt) is swung away from the position shown in FIG. 8 toward that shown in FIG. 9, the arm 172 of the lever 17o moves oif the roll 186 carried by the block 1&4, and the lever is returned by its spring 178 to its initial position, moving the toe gage 16S away from the shoe.

As the grippers 1tl8, in engagement with the inner face of the cover, are moved with the carrier 100, they pull the shoe ott the form 20 in a rearward direction until the wiper cams 124 again engage the rolls 134 and are rocked counterclockwise, as seen in FG. 9, causing the wipers 123 to turn the shoe in a counterclockwise direction into the substantially vertical position shown in FlG. 1t), where the platform P on the shoe engages a fixed abutment 198 secured to a bracket 200 which extends upwardly from a plate 202 fixed to the cross member 14d. As the shoe is turned by the wipers while the cover is held clamped between the upper and lower grippers, the margin of the cover at the tip of the shoe is turned outward about The shoe now being held by the abutment 19S against further movement, and as the operator continues to depress the treadle, the Wipers 12S are moved relative to the shoe to complete the turning of the cover C away from the upper U until it occupies la plane substantially at right angles to the plane of the shoe bottom.

At this point the operator releases the treadle and the carrier lll, which had been moved to a position somewhatrfurther to the left of that shown in FG. 1, is swung clockwise by its spring 146 until the detent 152 engages the pawl 154 to lock the carrier in its original starting position. During such clockwise movement of the oarrier, the arms are caused to swing clockwise to move the grippers 1% to their open position so as to permit the operator to remove the shoe. The clockwise swinging movement of each arm 110 is yieldingly limited by engagement with the underside of the cross member 141i of a leaf spring 29d secured to each arm.
