HEEL ATTAC'HING MACHINE Application January 6, 1943, Serial No. 471,412 In Great Britain February 11, 1942 28 Claims.

The present invention is concerned with improvements in the heeling of shoes, the term shoe being used herein to indicate outer footwear generally and the term heel to indicate either a completed heel or a heel-body which is not necessarily completed. By way of illustration, the invention will be herein disclosed with reference to its application to means suitable for use in carrying out a process of attaching together a heel and a shoe, wherein a plurality of fasteners are inserted into one of the parts, leaving portions of the fasteners projecting, and the shoe and heel thereafter pressed together so that the portions of the fasteners projecting enter the other part. Such a process may combine benefits of both inside heel-attaching and of outside heel-attaching. It enables, as is the case with outside attaching, the shoe to remain on its last during the attaching operation, and also as with inside attaching, the heel to have a top-piece pre-attached. Hitherto, in carrying out such a process, the operation of inserting the fasteners into one of the parts and the operation of pressing the parts together have been effected in separate machines. It is an object of the present invention to provide a single machine, so arranged that both operations may be effected therein. It is however to be appreciated, that features of the invention may also find application in machines not necessarily arranged to effect both operations.

The invention will hereinafter be described in connection with an illustrative machine compris ing means for inserting fasteners in the heel-seat of a shoe, and means for pressing together the shoe with its fasteners and a. heel to cause the attachment of said heel. Preferably, the fastener-inserting means also acts to mold the heelseat of the shoe, and means is provided for supplying fasteners to said inserting means. The machine may include a shoe-support having a work-positioning band-clamp and a jack or abutment. Slidable transversely of the machine and positioned below the band-clamp and abutment is acarrier upon which two operating mechanisms are spaced transversely. The carrier is so movable as to position either of the mechanisms in registration with the shoe-support. One of the mechanisms may take the form of a die-anddriver-assembly, including a nailing die provided with a molding surface and in which operate drivers. Distributing means is provided for supplying to the die a load of nails or other fasteners under the control of the carrier. Before the nails are driven into the heel-seat of the supported shoe, pressure is applied between the shoesupport and the die to subject said heel-seat to compression to mold it to a shape for the reception of the attaching surface of the heel. During the time the shoe is acted upon by the nailing and molding mechanism, it is held in position by the band-clamp. After the nails have been driven, pressure between the shoe-support and the nailing die is relieved, but the shoe is still held clamped under the control of the carrier. The other operating mechanism furnishes a heelholder, which by movement of the carrier is brought into registration with the shoe-support. Pressure is then exerted between the heel-holder and the shoe-support to cause the shoe and heel to be pressed together to causeattachment of the heel. The operation of the machine may be so controlled by the position of the carrier, that it can occur only when one of the operating mecha-v nisms is in registration with the shoe-support.

Portions of the illustrative machine are similar in many respects to the machine disclosed in Letters Patent of the United States No. 2,259,568, Kestell et al., October 21, 1941. There is similarly a band-clamp I (Fig. 1) arranged to en- .g-age the back and sides of the heel-portion of the upper of a shoe and to enter the crease formed between the upper and outsole. To furnish, with the band-clamp, a shoe-support, there is also a last-engaging abutment or shoe-pressing jack consisting of a member 3 for engaging the crown of a last applied to the lower end of a post 5 pivoted at 'I in a slide 9. This slide is mounted for fore and aft movement in a guideway formed in the underside of a plate II which is carried on the lower end of a plunger I3. The plunger is arranged to be moved heightwise of the machine to cause the abutment 3v to press against a last, and the band-clamp I' is mounted to partake of the movement of the. plunger. For this purpose, there is threaded into a trunnion. upon the plate II the upper end of a link I5, the lower end of which is threaded into a trunnion-block II on means carrying the: band-- clamp. The link I5 has left and right screwthreads on its ends to provide for determining the heightwise position of the band-clamp. Inasmuch as the band-clamp-supporting mechanism of the present illustrative machine is similar to that described in the previously mentioned patent, no further description of it need be given. For operating this mechanism there is provided a rod I9 pivoted at its rear end to the upwardly extending arm of a. bell-crank-lever 2I fulcrumed at 23 on the frame of the machine. The bell-crank-lever has a forwardly extending arm 25 to which is pivotally connected the upper end of a rod 21, which at its lower end passes through the fulcrum-stud 23 of a lever 3!, this stud being mounted in the frame of the machine. A spring 33 surrounds the rod 2'! between the lever 3I and a collar 35. fast on the rod, thereby serving to swing the lever 2I in a. direction to cause arms of the band-clamp to be moved into clamping relation. Latching means is provided to hold the springv 33 in condition ready to thus move the band-clamp. This latching means (Figs. 1 and 9) comprises an upwardly extending bar 31 connected. at its lower end to the forward end of the lever 3|, and a downwardly extending rod 39 connected to the rear end of the lever 3I and at its lower end portion to a clutch-throwout-lever 40. A small spring 4I serves to swing the bar 31 rearwardly of the machine to cause a latch-plate 43 on. the bar to engage a wear-plate 45 on the forward arm of the lever 2I to hold the spring 33 in compression and the band-clamp open. For moving the bar 31 to free the lever 2| for actuation by the spring 33, said bar has a pawl 41 ivoted thereon and connected by the spring 41 to the frame, it thus being held in contact with a shoulder on a block 49 secured to a horizontally extending rod 5!. The rod 5I is pivotally connected to a member 53' secured to the left-hand end of a shaft 55 rock through 'a link 54 upon depression of a machine-treadle 56. To the upper end of the bar 31 is secured a forwardly extending latch-bar 51 (Figs. 2 and 3), having a latching shoulder 58 formed on it forward endportion for a purpose later to be described.

From the front of the machine-column projects a bracket 59 having a vertical passage in which is guided a plunger 69 reciprocated' under power (Figs. 2, 9 and 10). Extending transversely of the machine and attached to the front face of said bracket is a horizontal guide-rail GI Situated behind this guide-rail are two other guide-rails 63 (Fig. 3), which extend transversely of the machine in the same vertical plane, each guide-rail 63 having at its inner end a forwardly and rearwardly projecting arm 65 through which pass clamping bolts 61 engaging the bracket 59. To give further support to the guide-frame formed by the three guide-rails, each of the two rear rails 53 is secured at its outer end to the upstanding arm of one of two U-shaped frames 69, 69, and the outer ends of the front guide-rail BI are respectively secured to theother upstandin arms of these frames (Fig. 1). The crossbars of the frames are bolted to the upper portions of supporting struts II secured at their lower ends to the machine-frame. A frame 13', furnishing a carriage or carrier, comprises two transversely extending members I5 situated one behind the other and supported by four rollers 11 riding on the guide-rails BI, 53, 63, it being slidable transversely of the machine. For so moving the frame I3, there is joined to a rod. mounted at its left-hand end the ends of a pair of toggle-links I9, which at their outer ends are pivotally connected to a second pair of toggle-links M. The outer ends of the togglelinks 8I. are secured by bolts 83 to a member 85 attached to a spindle 81 journaled in the upper portions of the upstanding arms of the left-hand frame 69. The forward end of the spindle 81 extends beyond the rail GI and has secured thereon a crank 89 by which the toggle-links 8| may be oscillated. to cause the frame I3 to be moved transversely of the machine.

At each end of the frame 13 is mounted a work-engaging and operating mechanism, these mechanisms having different functions. The right-hand work-engaging mechanism 9| comprises a. gang-nailing die and mold including a hollow post 93 with an upper section or top-plate 95. Mounted for vertical movement in the post is a plunger 91 (Fig. 2), having at its upper end a plate 99 holding a plurality of vertical nail-drivers IDI. The drivers operate in passages I I13 through the top-plate and are all provided. at their upper ends with conica1 recesses I05 for a purpose later to be described. Extending downwardly from the, plunger 91 is a stem I01. The post 93 is secured in a boss I09 on the frame I3, the right-hand lower end of the boss having a downwardly and inwardly inclined extension or stop member III. formed thereon. The upper surface of the top-plate. 95 is concave, to be complemental to the convex curvature which is generally desirable for the heel-seat of a shoe. The plate thus furnishes a mold, by pressure against which the heel-seat of a shoe may be formed.

The left-hand work-engaging mechanism is indicated at H3 and comprises a heel-holder and pressure means, including a hollow post H5 having formed in. its side walls. and near the top forwardly and rearwardly extending guideways II1 (Fig, 2). Tongues II9 formed on the sid walls of a. pressure-block I2| are loosely received in the guideways III. Movable vertically in the post H5 is a plunger I23 having a downwardly extending stem I25. The head of the plunger is provided with ways receiving a block I21 having three. upstanding dowel-pins I29. Mounted on the dowel-pins is a strikerplate I3I, the arrangement being such that by sliding the block I21 on the head of the plunger I23 and out of the. post II5, the striker-plate I3l may readily be exchanged for one of a different shape, the purpose of this being hereinafter explained. The upper face of the pressureblock I2I carries a heel-holder means I33, best shown in Fig. 3. It comprises an abutment I35 adjustably mounted on the plate. I2I for engaging the rear of a heel, a pair of fingers I31 for engaging the sides of the heel adjacent to the rear, a second pair of fingers I39 for engaging the sides of the heel adjacent to the breast and a heel-breast-engaging abutment MI. The abutment MI is pivoted midway of its length on the transverse arm I43 of an L-shaped slide I45, mounted for fore and aft sliding movement on the plate I2I. The right-hand end of the arm I43 is received in a slot in a guide I41 upon the plate I 2I, while the other arm of the slide I45 is guided in a cover-plate I49 (Fig. 6). The fingers I31 are each pivoted on the arm I43 by studs II and have intermeshing teeth I53, so that simultaneous movements about the pivotstuds of both fingers may be caused by actuation of an extension I55 from the left-hand finger I31. A spring I51 secured to the extension and to the cover-plat urges the fingers I31 inwardly towards each other, such inward movement being limited when no heel is present by engagement of the extension with the forward end of the cover-plate. The fingers I39, like the fingers I31, are pivoted on the studs |5I and have intermeshing teeth to cause them to move simultaneously and equally, and are urged inwardly by a spring I59 (Fig. 1) connected similarly to the spring I51. The left-hand finger I39 is provided with a forward projection having an upstanding lug I6I receiving contact of a projection I 63 formed on the left-hand finger I31, the construction therefore being such that both sets of fingers I31 and I39 are actuable by the same finger-extension I 55. The slide I45 is urged rearwardly of the machine by the two springs I51 and I59, and to limit this movement there is threaded through 2. lug I65 on the plate I2I a stop-screw I61, against which the rear end of the slide abuts. Near its front the slide is provided with an upstanding pin I69, lying in the path of the extension I55 when the latter is actuated to open the fingers I31 and I39. Upon contact of the extension with the pin, the slide will be forced forwardly to carry the fingers and the breast-engaging abutment I4I away from the rear end abutment I35, thereby facilitating the entry of a heel between the abutments and the fingers. For holding the fingers and the abutment MI in this position, there is secured to the cover I49 a hollow casing I1I (Fig. 6) in which is located a spring-pressed ball I13. This, when the slide I45 is shifted forwardly as above described, enters a recess I in the slide to maintain it in such forward position. It will be appreciated that th two sets of fingers I31 and I39 and the abutments I35 and MI conveniently determine the position of a heel on the slide I2! and hold it securely. The post II5 has a downwardly and inwardly inclined stopextension I11 (Fig. 2) formed at its left-hand lower face. Projecting to the right from its upper end is a latch-tripping member I19, adapted to co-operate, in a manner that will hereinafter become clear, with a clutch-tripping latch 2I9 of the fastener-supplying mechanism D with which the illustrative machine is provided,

The fastener-supplying mechanism operates in a manner generally similar to that described in Letters Patent of the United States No. 1,005,303, Pope, October 10, 1911. It comprises a rotary drum (not shown), which is adapted to discharge fasteners on the upper end of a reciprocating raceway I8I (Fig. 7) having a plurality of fastener-receiving grooves. The nails or other fasteners are delivered to a discharge device consisting of an elongated roll I83, extending trans 'verselyof the machine and having a series of passages I into which fasteners are introduced from the raceway-grooves. The leading ends of the fasteners project from the passages and abut against a stop-plate I89. This stop-plate is extended somewhat heightwise of the discharge device, since the fasteners intended to be used in the illustrative machine are nails pointed at both ends. Hence there is a tendency for succeeding nails to override the trailing points of the nails in the discharge device and to find their way on to its upper portion. When the discharge device is rotated to deliver its load of nails into fastener-receiving conduits 221, the overriding nails might, if not prevented from doing so, either fall into such conduits or prevent rotation of the discharge device. The stop-plate I89 is adjustable, as hitherto, toward and from the discharge device by a shaft I9I which carries two pinions meshing with racks I93 on the stop-plate.

Rotation of the discharge device I83 to cause fasteners introduced therein to be deposited in the fastener-conduits 221 is caused by a camsurface I95 (Figs. 2 and 8) formed on the front of a disc I91. The disc is connected by a link and lever (not shown) to a crank secured at the right-hand end of the discharge device. The disc is rotated only at such time as the load of fasteners in the discharge device is to be delivered to the fastener-conduits, and for this purpose it furnishes the driven member of an auxiliary friction-clutch, the driving member of which is mounted on a constantly driven shaft I99. A spring (not shown) serves to urge the disc I91 into contact with the said driving member, but rotation of the disc is normally prevented by a stop-projection 2IJI formed on the periphery of the disc and contacting with the end of a stopbar 203. The opposite end of the stop-bar is pivoted to a crank 205, fast upon the rear end of a rocker-shaft 201 journaled in brackets depending from the frameworkof the fastener-supplying mechanism. To the forward end of this shaft is secured a transversely extending rocker arm 209, connected by a link 2 to a transversely extending lever 2I3 (Fig. 2) fulcrumed between its ends bya stud 2| 5 upon a bracket 2| 1 attached to the machine-column. The opposite end of the lever has a depending latch 2I9 pivoted thereto, and engaged by the latch-tripping member I19 on the post H5 at certain times, as will later appear. A spring 22I (Fig. 8), connected at one end to the stop-bar 203 and at its other end to the frame of the fastener-supplying mechanism, serves normally to hold the stop-bar in the path of the projection 20I on the disc I 91 and the latch member 2I9 in position to be engaged by the latch-tripping member I 19.

The fastener-supplying mechanism Dis pro- .vided with a series of fastener-stops 223 (Fig, 7) which, when the discharge-roll I83 is rotated to deliver a load of fasteners, are allowed to descend by their own weight into contact with the lowermost fasteners in the raceways to hold them against downward movement. The fastenerstops are secured to a rock-shaft 225, the oscillation of which is controlled by the dischargeroll. The fastener-receiving conduits 221 into which fasteners are discharged by the roll I 83 are connected by flexible fastener-guiding tubes 229 to a carrier-bar 23I (Fig. 2) extending forwardly from the machine-column. Slidably mounted in grooves in the bar is the upper portion 233 of a guide-tube-assembly or mug 235.

This upper portion is connected to the main body- 'portion of the mug by a web 231, which forms a convenient handle by which the mug may be removed from the bar 23L Flexible fastenerguiding tubes 239 connect the upper and lower portions of. the mug, the arrangement being. such that fasteners delivered into the conduits 221 pass through the tubes 229 and 239 for delivery. This mug occupies such a position at the front of the machine that it lies just above the work-engaging mechanism 9t when the sliding frame 13 is moved to the right. Incidentally, when the device 9| occupies this position the heel-engaging mechanism 1 I3 is immediately beneath the bandclamp l of the machine. This is as appears in Fig. 2.. Fasteners delivered through the mug 235 will pass into the driver-passages. I03 in the top-plate 95 of the post 93. It will be understood that different top-plates may be provided for different types and kinds of heels where different nailing designs are required, and that mugs 235 corresponding in design may readily be substituted.

Secured. to the outer face of'the forward transversely extending member 15 of the sliding frame 13 is a bar 24l, forming part of safety means of the machine. Secured to the front guide-rail 6| is-a casing 243 having a vertical guideway in which is movable a safety-latch 245 (Figs. 4 and 5). On the rear lower end portion of the latch is a shoulder 241 for engagement with the edge of acover-plate 249 for the casing 243. This limits the upward movement of the latch under the influence of a tension-spring 25|. The lower end of the latch is joined by a rod 253 to the treadle of the machine. There is provided in the rear of the latch a notch 255 of just sufficient size to allow the bar 24| to pass therethrough. This bar is of such length that when either of the two work-engaging mechanisms 9| and H3 is positioned by the frame 13 for operation beneath the band-clamp, its corresponding end is just. clear of the notch 255, so that the latch wihnot impede movement of the treadle to set the machine into operation as hereinafter described. On the other hand, if the frame is so located that neither of the work-engaging mechanisms is thus positioned, the bar 24| will lie in the notch. 255 to prevent depression of the treadle and setting of the machine into power-opera- 'tion.

The illustrative machine is particularly suitable for use in carrying out that method of heeling shoes, which comprises inserting a plurality of nails in the heel-seat but leaving portions protruding therefrom, said nails being inserted while consolidating pressure is: applied between the outside and interior surfaces of the heel-seat. Thereafter, the shoe and a heel are pressed togather to cause the protruding nails to enter the heel to secure it to" the shoe. Conveniently, the nails employed in this method are without heads and collars. or like means to control the depth of insertion. and are pointed at both ends. In. using the machine a quantity of nails for carrying out this method are supplied to the drum of the fastener-supplying mechanism of the machine. Assuming that a gang of such nails N (Fig. 12) have been introduced into the passages I93 of the top-plate 95 of the worlcengaging mechanism 9|, when the elements were as illustrated in Fig. 2, the. sliding frame 13 will be moved to the left to carry this mechanism into operating position beneath the-band-clamp I (Fig. Here, the post will register with the bracket 59 and the stem of the plunger 91 with the power-operated plunger, 6|]. To ensure that the post 93 will properly occupy this position, the stop H on the boss I09 contacts with a complementally-shaped face 251 on the bracket 59. The operator will then take a shoe S (Figs. 11 and 12), which is preferably upon a last L having the usual meta1 plate I at its heel-seat-portion, said shoe having either a full-length outsole extending to the end of the shoe-bottom or an outsole which extends only just beyond the heel-breast-line and to which is joined a piece-sole at the remainder of the heelseat, apply it to the post 5, and position it bottom-down between the open arms of the bandclamp. He will then depress the machine-treadle. The first part of the depression of the treadle will cause rocking of the shaft 55, lowering the last-engaging abutment 3, together with the bandclamp I, toward the post 93 to cause the heelseat to be pressed against the mold-plate 95 with preliminary pressure. Just prior to the actual pressing of the shoe against the plate, the rod 5] will be moved forward to shift the latchplate 43 on the bar 31 away from the wear-plate 45 on the bell-crank-lever 2|. This allows the spring 33 to so move the lever as to cause the arms of the. band-clamp to engage the shoe (Fig. 11). Further depression of the treadl will .trip the clutch of the machine to initiate its poweroperation. During this power-operation the lastengaging abutment 3 will be lowered to cause the shoe to be pressed more firmly against the plate 95, thereby subjecting the material at the heelseat to considerable compression. Owing to th convexity of the plate, it exerts a molding action on the heel-seat to impart thereto the proper form for the reception of the cupped attaching surface of a heel. This action is maintained while the nails are driven, to ensure that the layers of material at the heel-seat will not separate or gape under the driving force. The naildriving operation occurs as a result of upward movement of the plunger 60 in the bracket 59, this plunger engaging the downwardly extending stem I01 on the driver-carrying plunger 91. The extent of upward, movement of the drivers is such that the nailsare preferably driven into the heel-seat until their entering ends contact with the last-plate, so these ends may be clinched slightly. The nails are preferably of such length, that, after driving, a portion of each nail at least equal to that which has entered the heel-seat will be left projecting from it. It will be appreciated that by providing fastener-drivers having conically-recessed end portions I05, more control of the double-pointed nails will be attained than would be the case if normal flat-ended drivers were to be used.

As the work-engaging mechanism 9| was moved into operating position, an upstanding latch member 259 (Fig. 2) on the sliding frame 13 engaged the latching shoulder 58 on the forwardly extending latch-bar 51 of the band-clamp. As the machine comes to the end of its poweroperation, the clutch throw-out lever 40 will be moved, and, through the rod 39, lever 3|, bar 31, latch-plate 43 and lever 2| will tend to open the arms of the band-clamp and cause the compression-spring 33 to be loaded. However, due to the engagement of the latch-member 259 with the latching shoulder on the bar 51, the'bar 31 will. be held against the action of its spring 4| from moving rearwardly to position the wearplate 43 above the latch-plate. Therefore, as the machine comes toa stop the band-clamp will remain in clamping engagement with the shoe into the heel-seat of which nails have just been driven.

The operator will now place a heel H (Fig. 13), which may be built up from a plurality of lifts, having a top-piece secured thereto and which has been both compressed and breasted, tread-end down and with its breast-face to the front, in the heel-holder I33 of the device H3. He will then move the frame I3 to the right to carry the work-engaging mechanism 9| from and to bring the work-engaging mechanism H3 into operating position (Fig. 2) This position is determined by engagement of the stop-extension I H of the mechanism I I3 with a complementallyshaped face 26I on the bracket 59 (Fig. 2). Depression of the treadle will then cause the lastengaging abutment 3 to be lowered, and since the shoe is held by the band-clamp (Fig. '11), the operator will not be called upon to exercise any great care in the determination of the relative positions of the shoe and heel, the relation being determined by the heel-holder means and the band-clamp. Power-operation of the machine, upon further depression of the treadle, will cause the last-engaging abutment to press firmly upon the last. This causes the descent of the shoe, so that the nails N protruding from the heel-seat will be thrust into the heel until the heel-seat and cup of the heel are brought firmly into contact (Fig. 13). The plunger 60 will also be moved upwardly to cause the stem I25 on the plunger I23 of the heel-engaging mechanism I I3 to move,

, through the block I21 and striker-plate I3I thereon, the pressure-block IZI of the device upwardly. This movement is possible because of the loose fit of the tongues H9 in the guideways In. It will increase the pressure exerted between the heel and shoe and will ensure firm attachment. Further, if it is desired to exert more pressure between the forward breast-portion of the heel and the heel-seat than at the rear, the strikerplate I3l may readily be exchanged for one of a different form, as wedge-shaped with its upper surface tapering rearwardly and downwardly.

As the machine nears the end of its poweroperation, the arms of the band-clamp will be opened and latched in this condition thereby releasingvthe shoe for removal from the machine. This follows, since in moving the frame I3 to the right to bring the heel-supporting device I I3 into operating position, the latch member 259 will have been moved away from the latching-shoulder on the bar 51. As the frame is moved to the right, the latch-tripping member I19 will engage and move the depending latch member 2I9. This will cause the lever 2l3 to rock in a clockwise direction (Fig. 2), moving the stop-bar 203 away from the stop-projection 2III on the periphcry of the disc I91 to allow the disc to be rotated. The roll I83 of the fastener-supplying mechamsm is therefore rotated to allow the nails delivered by the raceways I8I to the passages I85 to be deposited in the fastener-conduits 221. From the fastener-conduits the nails will pass through the mug 235 to the post 93, in readiness for succeeding operation.
