SHOE'HEEL NAILER William W. De Rusha. Gish, Minne St. Paul, apolis,

and Lewis L. Minn.

Application June .9, 1937, SerialNo. 147,282 3 Clainis; (o1. 1 32) object of this device is to provide a simple, highly efiicient heel attaching device I arehereinafter fu-ily set forth, reference being had to the accompanying drawings, in Which metal base.

From said base extends upwardly (as 'inFigs. 1, 2 and 3) a. pair of rigid posts I 0, and in Fig. 4 a single rigid post IOA. l I is a horizontal cross bar rigidly connecting the the posts is formed and .projectible upwardly. l4I-I Figs. 1-3 inclusive, l4 designates (as a whole) \a hydraulic jack mounted rigidly on base 9 intermediate the .posts l0, its lifter member or MAreciprocable vertically in its central part is the necessary of a heel to a shoe. v tained .a plunger .l'l'fixed at its lower end in a To prevent side slip of the shoe and to hold the heel further rigid and prevent splitting of it we provide a pair of adjustable clamp members engaging the opposite sides of the heel at its base and capable of being adjusted to thus clamp the heel at opposite sides. These members comprise each a collar 22 rotatable on a post In and movable vertically and supported on a collar 23 on the post, each collar 22 having an upright projecting lug 22E threaded to receive a threaded clamp rod 24 in approximately horizontal plane, or inclined plane, the inner end of each rod 24 pivoted in a heel engaging pad 26.

Each collar 22. is keyed to its support collar 23 by means such as a dowel 21 when the heel clamp member is positioned to engage the side of the heel as in Fig. 2. Said clamp members are adjusted firmly against opposite sides of the heel simultaneously. At this point it will be readily understood that the shoe and'its heel are firmly held in position.

Assuming now that the required number of nails 2! have been placed in the proper bores of the last member l5, said nails are forced into the heel of the shoe by simply actuating the hydraulic jack lever MH forcing the ram MA, the plates l8-l9 and plungers l1 upwardly the nails driven simultaneously by the latter into the heel. The plungers may be of such length that they will drive the heads of the nails into the shoe flush or deeper, and when the nailing is thus completed the plungers and associated parts are restored to original position by compression coil springs 28 (see Figs. 3, 6 and 7) or a rubber pad 28R placed between the plate l8 and the head piece [5H as in Fig. 4.

The nailing head is modified lIl Fig. 7 being without the sole supporting tongue, this head therefore being smaller and comprising a desirable form of nail driver for the lift 25H of a heel, the plungers I1 being grouped more closely together for insertion of nails in the smaller end part or lift of a heel, the contour of such lift by dotted lines 25H in Fig. 8. To the shoe is positioned as in Fig. '7 (lift end down) to contact the upper face oi member Hi, the shoe being held rigidly by direct downward contact of the flared lower member I2L of the threaded rod 12, inside the shoe. The number 12L is also provided with prongs l2L which engage the shoe and prevent slip or twisting tendency.

In the simpler, modified form of our device illustrated in Fig. 4, the last member l5 pressed upwardly within the shoe is reciprocable vertically and the plunger retaining plate I8 is stationarybeing sui ably keyed and resting on the upper horizontal face 29F of a metal frame 29 having a base 29B removably and adjustably secured to the top face of base 9, as at 30. The last member is retained slidably (vertically) by means of downwardly extending rods 31 extending through corresponding bores part of the goose-neck frame 29 and plate I8. The nail driving action is the same scribed that 15 the nails are forced into the heel by the plungers except that in this modification the plate l8 and its plungers are stationary and the last member downwardly by the screw member I2,yoke l3 holding and forcing the heel part of the shoe down and the nails are simultaneously positioned in the heel. This modified form of the device is of course a most inexpensive design but is very eflicient though of slower action.

. pleted with this It is well known in the art that in the making or repairing or replacement of shoe heels, particularly on womens shoes, there is considerable waste and expense caused by split heels or improperly mounted heels. In the form of our device shown in Figs. 1, 2 and 3 these losses are eliminated. Obviously the heel engaging and clamping means securely holding the heel while nailing prevents splitting of the material of which such heels are usually made.

Also when the nailing of a heel has been comdevice the heel end of the shoe and the heel are rigidly positioned and the breast of the heel and adjacent bottom part of the shoe are in convenient position to secure thereto any type of shoe-heel brace.

The heel side-clamping members it will be readily understood can be disengaged and swung free as to the pos'tions shown in Fig. 1 from the position shown in Fig. 2. First the heel clamps are released from their clamping positions, then the collar 22 is raised until its dowel pin 21 1s unseated after which the collar and its rod 24 can be swung around, the dowel pin 21 riding on the upper end face of the stationary collar 23. Thus is provided ample clearance between the posts In for the operator to place a shoe in position or to remove it from the nail driving zone.

Modifications in structure other than those shown may be embodied in constructing the device without departing from the scope and spirit of the invention.

We claim:

1. A shoe-heel repairing device comprising a base, an upright frame on said base, support means in said upright frame for removably holding the heel part of a shoe in inverted position, means mounted on the frame for adjustably and frictionally engaging and clamping the Shoe heel from opposite SldeS and corresponding adjustable means over for engaging the latter downwardly, a nail driver member below said shoe heel support comprising in part a plurality of upwardly directed plungers the shoe a nail, point up,

vertically actuated which said plungers are reguided in bores in bore adapted to retain driver member in tained, said wardly to drive the nails into the shoe heel, said upright frame comprising a pair of upright posts, said nail driving means mounted intermediate said posts, a cross bar connecting the upper ends of the posts, said shoe heel clamping and lift contact means comprising a pair of threaded rods, one for each post, a sleeve on each post movable longitudinally and rotatably within predetermined limits thereon and having a threaded extension lug for the threaded rod, one end of the latter having a foot piece adapted to be adjusted by rotation of the rod toward and into engagement with a side of the shoe heel, and a single vertically adjustable screw rod threaded through the top cross lower end adaptable for frictional engagement with the lift of the shoe heel. 1

2. A shoe-heel building and repairing device comprising a base, an upright frame on said base, support means in said upright frame for removably holding the heel part of a shoe in inverted position, means mounted on the frame for adjustably and frictionally engaging and clamping the shoe heel from opposite sides and corresponding adjustable means over the heel lift for engaging the latter downwardly, a nail driver heel and its upper end arranged to bear simulmember below said shoe heel support comprising taneously against the shoe heel lift, downwardly, in a part a plurality of upwardly directed plungas shown and described.

said upright frame comprising a pair of upright ing'of the shoe heel from opposite sides, and 10 mediate said posts, a cross bar connecting the engaging the latter downwardly, a nail driver I upper ends of the posts, said shoe-heel clampmember below said shoe heel support and oscil- I WILLIAM W.
