ATTACHING MACHINE.

Application filed August 3, 1923. Serial No. 655,518.

My invention relates to attaching machines, as those of the type disclosed in Patent No. 1,382,762, Conner, June 28, 1921,

for securing a molded counter to the heelseat-portion of a turn-shoe.

In such machines, the counter to be attached is held in place upon a block or extension-piece immovably under side of the die-block of a nailing apparatus generally resembling the wellknown lightning heeler. This block enters between the upstanding sides of a counter, and holds it in a definite relation to a jacked shoe when this has been pushed into the nailing position beneath To change the relation between the counter and heel-seat preparatory to attachment, so that the shoe shall be of the correct size, the point at which the jack is arrested is determined by an adjustable back stop. The fixed character of the holding device for the shoe-part to be attached is disadvantageous in some respects, and an object of this invention is to provide, in an attaching machine, for a variation in the position of the part to be attached as it is held by the device, as by changing the effective dimensions of the latter. More specifically, I efiect this change bothlongitudinally and transversely of the element. In connection with the longitudinal alteration, it may be said that adjustment of the back stop of the abovementioned patent, to determine the location of a counter upon a shoe, is somewhat difficult for the operator, because the adjusting means is at the rear of the machine. I accomplish a similar result by movement of a gage member through the counter-engaging wall of the holding device toward the rear of the machine, with means at the front of said machine, convenient of access by the operator, for adjusting this gage member. The transverse adjustmentrenders the holding device applicable to such objects as counters, which are without the usual trucks secured to their flanges and spacing the side walls a constant distance apart. tucks omitted, as is sometimes desired by manufacturers of turn-shoes, there is nothing to hold the peripheries of the counters in the proper relation to the outer edges of the heel-seat-portions of the shoes, the springsecured upon the the die-block.

With the clips of the holding blocks tending to press the sides of the counters closer together than they should be when secured upon the shoes. WVith the transverse adjustment of the hold-' ing device, which may be accomplished by gages movable through the engaging walls at the opposite sides of the device, the sides of each counter may be, in all instances, correctly located with reference to the shoe to which it is to be attached.

One of the several embodiments which my invention may assume is illustrated in the accompanying drawings,

Fig. 1 being a side elevation, with parts in section, of the portions of a counter-attaching machine more closely -co-operating with the work;

Fig. 2, an enlarged front elevation of the center of the die-block andcounter-holding block I Fig. 3, a central vertical longitudinal section through the counter-holding block; and

Fig. 4:, a full transverse section therethrough on the line 4.4i of Fig. 3. i

There appear in the drawings only those portions of a counter-attaching machine which are 111 direct association with the elements of the present 111VG111310I1. These include a die-block'lO mounted upon a frame 12 and having in it vertical openings 14L to receive theattaching nails or tacks. Entering these openings are drivers 16 depending from a top grit 18 carried by vertically reciprocatory side rods 20; In horizontal ways 22, carried by the usual pressure-applying mechanism, is a ack 24, shown as having upon it a lasted shoe S. This ack is movable 1n the ways from its outer position, in whlch the work is placed upon it, to that illustrated in Fig. 1, in which the heel'seat-portion of the jacked shoe is alined withthe openings 1% in the die-block. Fixed in place upon the under side of the die-block and having openings 26 registering with the openings 14; is

a counter-holding block or extension-piece 28. The periphery of this holding block has substantially the horizontal contour of a counter which is to be attached, having a side wall 30 curved similarly to the interior of the counter, and a vertical breast-wall 32, which comes between the'spaced ends of the counter. Spring-clips 34c, 34, projecting Cal over the wall adjacent to the breast-wall and adjustably mounted upon a transverse screw 36, press toward the blockan applied counter and serve to retain it in place. A spring-clip 37 depends from the die-block at the backof the block 28, for engagement with the counter at this point. To permit this clip to co-operate properly with a gage member hereinafter described, it should possess sutiicient yieldability to allow thecounter to be forced rearwardly to some extent. Mounted to move with theja-ck is a back stop 38 carried upon the upper extremity of a rod 40.

the sole to correctly locate the shoe beneath the block for cooperation with the counter which is to be nailed upon it. 'The rod 40 is engaged bythe head of ascrew 42 threaded horizontally through a bracket secured to the frame and adjustable by means of .a nut 44 rotatable between spaced walls of the bracket. By turning this nut to advance or retract the screw, the position of the back stop, and consequently the relation of the engaged shoe to the counter, may be changed.

The counter-holding block 28 is shown as fonmed in two sections horizontally divided, there being in one of these sections, preferaab-ly the upper, a groove extending centrally and longitudinally of the block. Arranged to slide in this groove is a bar 46 having projecting through the rear of the curved wall 80 of the block an end 48 furnishing .a back gage. Upon. the forward extremity of the bar is an upstanding lug-50, in which is a horizontal, threaded opening to receive a screw -52. This screw carries flanges 54, 54 rotatable upon opposite sides of .a wall 55 of the block. The head 56 of this screw lies outside the breast-wall 32, where it is directly in front of the operator and entirely clear of the work. Ordinarily, the initial adjustment to determine the relative longitudinal relation between the jacked shoe and the counter which is to be secured to it would be provided for by the adjustmentof the back stop 88. The rear edges of the shoe-soles, however, vary considerably in their extension against the portion of the upper which contacts with the. back stop, bjecause, being in temper, they are likely to be deformed. If, ha-vingbrought the heel-seat-portion of the shoe beneath the block 28 and the .counter which it sup ports, the operatorobserves that the vpoint of attachment of the counter will not be far enough back on the sole, a condition which would make the resulting shoe shorter than the true size, he can remedy this by .adjust ment of the gage-bar 46. To do this, he has only to turn the readily accessible head-56, forcing out the-end-portion 48, so that the counter is displaced somewhat rearwardly This stop contacts with the rear of the jacked shoe-upper outside the edge off ect to be attached,

upon the block 28 until such counter is correctly located over the heel-seat. The attaching operation having been effected, the operator may return the gage to its normal position.

Below the bar 46, adjacent to the breastwall 32, and extending transversely of the block 28, is a horizontal bore, in which are mounted opposite tubes 58, 58 having their closed, rounded ends outside the block-wall 30 to act as side gages. The interiors of these tubes are oppositely threaded to receive similarly threaded portions of a screw 62. Extending into the block, through the breast-wall 32, is a slot lying between the gage-tubes 58 "and receiving a flange or finger-piece 64 secured at the center of the screw 62. The periphery of this finger-piece projects beyond the breast-wall, and is preferably -nur-le'd so that Y it may be turned conveniently by the op erator. By rotating the-screw 62 by means of its finger-piece, the ends of the gage-tubes may be projected from or drawn into the openings through the wall 30 of the block, furnishing adjustable abutments against which the clips 34 may clamp the su ppono ed counter with its sides prope'nly spaced to ,agree with the outside of the heel-seat-portion to which it is to be attached.

count of the position of the finger-piece 64, this adjustment of the ends of the gagetubes may be varied readily by the operator when the sizes of the counters change.
