The operator `will then move the counter lfor wardlyJ until the wider opening in the heel por tion’ of the counter is reached and then down caused to release- the grippers so that the assem bled upper can be removed from the machine.` wardly to engage its rear wall with the clip 2d Referring now to Figs. 1 and 6, it will be seen and to bring the counter flange into alinement that the machine frame comprises a hollow base 30 with the plate 20. After the counter has been Iû which encloses the treadle mechanism of the dipped in the cement and returned to the drip ` machine and a head I2 which forms a housing ping position shown in Fig. 8, it is removed from for the major part of the operating mechanism of the machine. Attached to the side of the head I2 (Fig. 3) is a cement pot I4 and means, which will now be described, for immersing a counter in the cement and handling itprior to the actual assembling operation. ' “ Counter cementíng unit The counter cementing unit-consists of the pot It which is open at the top and contains a sult able quick-setting liquid cement. The’pot‘is lo cated on the left sidey of the machine with its . upper surface at approximately the level of the top of the machine -head I2 and is fastenedf to the headby bolts I5 (Fig. 8) which pass through y the support by a counter transfer mechanism which reverses the movements of the counter when being placed on the support. The counter transfer mechanism is operated by the machine through mechanism which will hereinafter be de scribed, the machine operation being initiated by the manual operation of a yclutch lever 214 (Fig. 1). ' - The counter transfer mechanism comprises a pair of levers 5d and 52 (Fig. 3) which are locat ed - rearwardly of the cement pot counter support and arev provided with counter gripping means consisting of a pair of bars 65 and 6B which are pivoted respectively on the ends of the levers and are each provided with two transversely-extend the side wall of the head and thence through ing counter-gripping needles 1D. The levers 50, hollow lugs IS which extend out from the side 52 are pivotally mounted one one end of a crank 50 of the pot Iâ. arm 54 and are caused to move in unison- toward Counters to be dipped in the cement are placed and away from each other by intermeshing gears on a carrier which consists of a i'lat plate 2li 62 and 54 formed on their adjacent ends. The (Fig. 20) shaped to'flt within the inturned flanges other end of the crank arm 54 is provided with a collar 55 which is clamped to a hollow shaft 55 when immersed inthe cement. The plate is pro that extendsy longitudinally of the machine mid vided with a depending flange 22 (Figs. 12 and way betweenthe cement pot counter support and 26) having a clip 2d which is adapted to engage a U-shaped counter support 58 (Figs. 8 and 20) the back of the counter and hold it in a vertical mounted on thetop of the head I2. position with its inturned flanges positioned op posite to the sides of the plate 20. The plate is- do Thelcounter gripping means is caused`to take hold of and release a counter by the action of t supported by a pair of spaced parallel links’26, a link 82 (Fig. 3) which is connected to the lever 2B which are pivoted at one end to heightwise 52 and rotates the same when moved forwardly spaced points on the depending flange 22.4 The or rearwardly with respect to the arm 54 by the lower link 28 is fastened at its other end to a movement of a longitudinally reciprocating rod pin 30 carried by a ~bolt 3l mounted in the en_d 84, as hereinafter described, rotation of the lever wall of the pot> I4, while the other end of the 52 causing -a corresponding vmovement lof the upper link 2B is connected to a shaft 34 which lever 5i) through the action of the gears 62, 64. . is journaled above the pin 30 in the side walls After the counter gripping means takes hold -of of the pot. Due to the parallel arrangement of counter, the shaft 56 is rotated to transfer the the links 26, 2B, the plate 20 is held in a hori 70 acounter to the U-shaped support 58,`the rotation zontal plane during the dipping operation so that of the shaft being effected by the action of a the walls of the counter will be coated without of a molded counter- and prevent it from tilting l getting cement on the inturned ilanges. The shaft 34 extends beyond the inner side ‘ segmental gear 'I6 on an elongated pinion ‘I4 which is fastened to the rear _end of the shaft 56. When of the pot It (Fig. 3) where it is connected to 75 the arm 54 is rotated, the link 82 is caused to 4 2,275,445 rotate with it by the action of a pair of spaced arms 'i8 and 80 (Fig. 20) which project out from the blank portion of the pinion 'it and receive the rear portion of the link between them. The shaft 56 is mounted in a bearing 60 which is shorter than the distance between the adjacent ends of the collar 55 and the pinion 14 (Fig. 3) so that the shalt 56 can be moved rearwardly in the bearing >during the early part of the counter = . transferring operation to move the wider part of the counter opening at the. front of the counter opposite the plate 20 as the counter is raised from the carrier bythe arm 54 and thereby avoid opening the counter wings an appreciable amount when thev counter is moved upwardly Y past the plate. The teeth on the pinion 14 are of such length that they will remain in mesh' with the teeth in the gear segment ‘I6 at all times during the axial movement of the shaft 56. The hollow shaft 56 is moved back and forth . in the bearing 60 by the rod 84 (Figs. 3 and 9) which 'ls mounted in the hollow shaft and is fric tionally coupled with the shaft by a spring tion of its operation. At the beginning :of an assembling operation, that is, when a counter is placed on -the cement pot counter carrier, the arm 54 is positioned a slight distance rearwardly of the position shown in Fig. 3, and the clamping levers 50, 52 are spaced wider apart than they are shown in that ligure. When the counter is ready to be taken oiï the support, the operator initiates the ñrst machine operation by moving the clutch lever 214 to the right, as viewed in Fig. 1. This causes the rod 84 to move to the left, as viewed in Fig. 3, carrying the shaft 56 and arm 54 with it until the pinion 14 strikes the bearing 60 after which continued movement of the link 82 causes the levers 52 and 50, through the action of the gears 62,64, to move inwardly toward each other until the needles ‘l0 grip the sides of the counter. Axial movement of the rod 84 is then stopped fora moment and the shaft 56 is rotated to release the counter from the . latch 24 (Fig. 26) and raise the inturned counter > flanges above the plate 20. . As the counter pressed bar 86 which is seated in a groove formed in the rod. The bar is forced against the inner , wall of the shaft 55 by a long bowed spring 88 (Fig. 3) which is conñned between the back of the bar 06 and the bottom ofthe groove formed in the rod. Thus, when the rod 86 is reciproc ated, the friction betwen the bar 86 and the ; inner wall of the shaft 56 will cause the shaft to move with the rod until either the sleeve '55 or the pinion 74 strikes an end of the bearing 65 whereupon the shaft 56 will stop and the rod ñanges move above the plate 20, the rod 64 is moved sharply to the right, as viewed in Fig. 3, partly to withdraw the counter from the support while the plate 20 is in the relatively wide mid section of the counter. During this movement c-f the rod 84, the shaft A5|i continues to rotate but at a slower rate and concomitantly raises and tilts the counter so that the counter assumes an angular relation with respect to the plate 2li. Aft-er the counter assumes a desired angular relation with respect to the plate 20, the rate of the rear ward movement of the rod 84 is reduced. Con lI’he mechanism ;,- tinued rotation of the shaft 56 causes the plate 84 will continue its movement. which reciprocates the rod 64 is arranged to con- .« tinue the movement of the rod for a short dis tance after the movement of the shaft 56 has been stopped by the bearing 50 and this addi walls. The gear segment 16 continues to rotate> the shaft 56' until the counter is seated flange downward on vthe U-shaped support 58 (Fig. 20). tional movement of the rocl is utilized to open and close the counter gripping means. The con trol of the counter gripping, means is effected through the link 82 which is connected to the rod 84 by a plate 81 (Figs. 3 and 23) attached to an arm 85 formed on the rearwardly projecting end of the rod 84'. When the counter is seated on the support 58, a clamping iinger 90 (Figs. 18 and 24) is moved, in a manner which will hereinafter be described, to ' a position where it clamps the inturned counter flange against the support 58. As the counter is clamped against the support 58 by the finger 90, the arm 54 strikes the bearing 60 stopping the rearward movement of the shaft 56. The rod The rod 84 and the pinion 14 are operated by a cam 92 (Figs. 11 and’lß) mounted on a shaft 94 which is coupled toy the main the machine by a clutch 96 (Fig. 92 is located outside of the head the cement pot I4 and controls drive shaft of l). The cam l2 adjacent to the pinion 14 64 continues to move to the right after the arm 5ft stops, thereby causing the link 82 to move rearwardly relatively to the arm 54 and move the clamping levers 50, 52 away from each other through a lever 98 which is connected at its up per end to the pinion 14 by a gear segment 'I6 sufiiciently to release the counter. When this is and at its lower end to the cam by a follower roll 95 which travels in a peripheral cam groove 53. The lever 08 is pivoted intermediate its ends on a bolt 99 which extends longitudinally of the head i2 and is supported by a lug @l that projects out from the side wall of~ the head. The cam 92 `>controls the movement of the rod 54 'through a linkage system consisting of a bell crank lever |00 one arm of which is connected to the rod 04 ky a link |02 and the other arm of which is con nected by a link |04 to a cam follower |03 which travels in a cam groove |05 (Figs. ll and 18) formed in the side of the cam 92 adjacent to the side wall of the' head i2. The cam follower |03 is also connected to one end of an arm |06, the other end of which is pivotcd on a transversely extending bolt~ |08 (Figs. 18 and 19) mounted in the side wall of the head |2 beneath the pivot of the lever |00. I ' A better understanding of the counter transfer mechanism can probably be had from a descrip 20 to pass through >the top and front counter openings thus effecting the' withdrawal of the counter without appreciably springing its side done, the gear segment 16 reverses the direction of its movement and moves the arm 54 backward to its position at the beginning of the operation. » This position is opposite to the full line position of the arm 54 shown in Fig. 20 and itA will be seen IH that that position is rearwardly of the dotted position of the arm 54 which is the location of the arm when the counter is placed on the sup port _58. v - Upper assembling After a vcounter has been clamped upon the s‘-pport 58, the operator takes a lined upper in his hand, separates the quarter lining from the upper, and slips the upper over the counter, the tcp of the head |2 and` the back side of the support 50 forming a guide for positioning the heel vpu'tion of the upper. A number of grippers are then attached to the upper, the grippers con sisting of a pair of heightwise-spaced back seam grippers which engage the top and bottom of the f 2,275,445 ward movement of the arm | 66 causes a corre upper along the back seam and stretch Ithe heel sponding upward movement of the link |68 which lifts the» front end of the member |36 about its end of the upper in a heightwise direction; a pair of widthwise-spaoed grippers which grasp . vpoint of connection with the links |38 as. a cen l, the lasting margin in the inside> and outside ter; thelinks |38, being anchored to the top Ul shank portions of the upper; a secondì pair of widthwise-spaced grippers which grasp the last of the head I2, act as a fulcrum for'the member |36.

The pull exerted on the upper by the _ grippers causes the heel part oi' the upper to lie tightly against the heel end of the form, there by shaping the heel end of the upper about -the form and firmly bonding the lining, counter, and upper together in proper relation to one another, »while the pressure of the bottom of the -form against the underlying lining margin and counter flange firmly bonds the two together. After a ' short interval, sui‘ñcient to permit the quick setting cement to form an initial bond between the lining, counter, and upper, the form is moved out of' the upper and all of the grippers are au tomatically released. > ‘ The mechanism for effecting the above opera tions consists of a cam 280 which is located .' within the head i2 and is keyed to the driven shaft 98 (Fig. ll). The heightwise movement of the form 210 (Figs. 16 and 18) is jointly con trolled by cam grooves 282, 404 formed, respec tively, in the opposite side facesof the cam 280.l the lever is moved in a counterclockwise direc tion to raise the form. The linkage system con sists of a link _308 (Figs. 16 and 18) which is connected at one end to the upper portion of the - lever 286 and at its other end to the arm 3v|0 of a cam 3|2 which is mounted on'a transversely extending rod 322 supported bythe side wallsA of the head |2. The face of the cam 3|2 engages a roller 3|4 on a slide bar 3|6 which is urged to ward the rear of the head I2, or to the right as viewed in Fig. 18, by a spring 320 which is con nected'at one end to the bar 3|6 and at its other end to the rear wall of the head. The rod 322 passes through an elongated slot 324 formed in the rear portion of the bar 3|6, the slot per mitting forward or rearward movement of the bar with respect to the cam as different por tions of the cam act on the roller 3|4 and cause the displacement of the bar. The forward end of the bar 3|6 is connected by a pin 326 to the upper end of a, supporting arm 328 which is piv oted on a rod 330. Also pivotally mounted on acreage the rod adjoining the arm 32d is a rearwardly extending linlr 332 which is connected to the lower end of the clamping ringer [email protected] by >a screw 336. The portion of the clamping ñnger Sil which lies opposite to the bar elli is provided with a caused by the lengthwise pull imparted to it by the toe and tip-line-grippers. IAs the form 21D moves up into the upper, the j lower portion of the lining adjacent the side walls of the counter is stretched inwardly away from laterally extending pin 335 which passes through the side walls, ln a manner which will now be described, so that the margin of the heel seat face of the form, as it moves downwardly, presses an inclined slot 338 formed in the forward end of the bar äilä, the> pin'being urged toward the rear end of the slot by a spring [email protected] which is con nected at one end to the ñnger 90 and at its; other end to the rear end of the bar 316.

When the operator smooths the lining against the inner walls of the counter, the margin of the lining will lie over the inner ends of a pair of transverse levers 368, 370 (Fig. 21) which are positioned opposite to the side walls of the counter (Fig. 3). The levers 368, 370 are pivoted, respectively, on pins 372, the upper shaping form 2li] is raised, the bar 3l6 is moved in a forward direction from its posi tion shown in Fig. i8'. The initial portion of this ' movement causes the pin 335 to ride upwardly in the slot 338, thereby lifting the finger 90 from the counter ñange, and continued movement of the bar after the pin contacts the rear wall of ‘ the slot carries the linger with it to the position shown in Fig. 16 where it is clearof the rear wall ~ of the form Zlli. Located rearwardly of the bar SIB is a latch 36!) which holds the finger @d in its inoperative position shown in Fig. 16 until the appropriate time during the counter transfer operation when a raised portion 356 of the cam 283 moves the latch to an inoperative position, thereby releas~ ing‘the linger and permitting it to clamp the counter flange against the counter support. The latch consists of a forwardly extending arm 354, which engages the rear end of the bar 3 I6, and a 314 mounted on ears on the top of the head l2 adjacent to the side walls, the outer arms of the levers projecting beyond the sides of the head and being urged downwardly by springs 375, while the inner arms of the levers extend toward the center of the head and are substantially V-shaped so that they pass beneath the ilange of a counter on the support 58 (Fig. 20). As the heel end of the form 2lll is moved into the heel end of the upper,- a bar 366 (Fig. 18) moves ahead of the heel end of the form and grips the lining ben -tween it and the ends of the levers 368, 310, as shown in Fig. 21. As 'the heel portion of the 30 form continues to move toward the support 58, depending arm .364, which carries a roller 353 that engages the peripheral face of the\carn- 28d. During the counter transfer operation, the raised portion 356 moves beneath the roller 353, caus- ' the bar 366 continues its downward movement, carryingthe levers with it, and thus pulls the margin of the lining downwardly, thereby caus ing the bottom portion of the lining to stretch inwardly from the side walls of the counter over the counter flange. While the lining is stretched in this manner, the margin of the heel seat face ing the latch toV move sufficiently in a counter clockwise direction to carry the arm 364 out of engagement with the rear face of the bar 3ft, of the form 210 moves into engagement with the thereby permitting the spring 32u to move the slide 315 to the right, as seen in Fig. 16, and swing 40 counter flange and as it does, it pulls the lining Yinwardly from the levers 368, 310 and the bar 366 the finger 90 against the flange of a counter on ’ and lays it smoothlyagainst the counter flange . the support 63.

As the form [email protected] is raised, the lever 2% acting through a spring 3182, causes the toe gripper 26d to take hold of the upper and exert a lengthwise pull on the same, the spring 3&2 being connected at one end to the lower arm of the lever 28d The bar 366 is integral with the upper end of _ a slotted plate 390 (Fig. 21) which is located be tween the arms 296, 298 (Fig. 22) and is coupled with the arms by a pair of heightwise-spaced pin and-slot connections which permit the plate to move relatively to the arms. The connections `are formed by a pair of slots 392, 391i in the plate #[email protected] (Fig. 18), the slot 39d receiving the pivot pin 308 that connects the arms 2%, 2% to the form (Fig. 22) and the slot 392 receiving a pin dat extending between the arms 296, 29d. The lower end of the plate 396 is connected by a pair of links 38d, 386 (Figs. 18 and 2l) to the rearward (Fig. 18), which moves rearwardly during the upper-raising operation, and at its other end to .end of an ofl’setr arm 31B, the forward endcof the lower end ofthe lever 351213. When the lower which is pivoted on a rod 380.

The rear end of the bar 468 is pivoted to the forked head of a rod 466 which is slidably mounted in the front wall of the clutch housing. The rear end of the rod is fastened to a‘plate 461 which abuts the hand lever 214 and carries at its lower end a' pin 465 which extends into a recess in the casing and is urged |to the left, as viewed in Fig. 1, by a spring 469- which is con fined in the bottom of' the recess. The pin 465, due to the action of the spring 469, tends to move the bar 468 to the left, as viewed in Fig. 1, and in addition, it prevents the rod 466 and the bar 4:38 from rotating and thereby moving out of proper relation to the other parts of the clutch.

'I'he motor 440 is connect ed with the shaft 94shaft by a442 transmission (Fig. 16) , a system driven ' comprising a driving form into the upper. The connections between the latch 414 and the treadle mechanism consist of a bell-crank lever 416 -(Fig.- 1), one arm of which is connected by a link 418 to the yoke 246 shaft 444 (Fig. 11) , and the clutch 96.

The crank arm 480 is fas tened to one end of a shaft 484- which extends transversely of the head I2 and is connected at its other end (Fig. 14) to the latch 414. The link 482 is connected to the crank arm 488 by a loose connection which permits the -latch to move rear wardly with the bar 468 without releasing the same in the event that the hand crank 214 is in advertently’v operated before the grippersv are lasting operation. As the form moves into the upper, the margin of the heel seat face contacts the lining at a point between the top edge of the counter and the counter flange, and wipes the lining downwardly as it moves toward the flange. properly adjusted. The connection between the link 482 and the crank arm 480 consists of a sleeve 486 which is pivoted to the crank arm and is slidable on the link between a collar 488 formed on the link and a spring 490 which surrounds the rear end of the link and is held thereon by a nut 492.
