OF LYNN, MASSA- MACHIN'E FOR APPLYING HEELS TO BOOTS AND SHOES.

Specification forming part of Letters Patent No. 31,690, dated March 12, 1861; Application for reissue filed June 5, 1874.

To all whom it may concern:

Be it known that I, JACOB JENKINS, of Lynn, in the county of Essex and Commonwealth of Massachusetts, have invented a new and useful Machine for Heeling Shoes; and I do hereby declare that the following is a full, clear, and exact description of the constructionand operation of the same, reference being had to the accompanying drawings, forming a part of this specification in which Figure 1 is a side elevation of the whole apparatus; Fig. 2, a detached perspective view of the upper rotary heel-bed and Fig. 3, a top view of the lower rotary heel-bed.

Like parts are represented by the same letters in all the figures.

To enable others, skilled in the art, to

make and .use my invent-ion, I will 110w describe its construction and operation.

The nature of my invention consists in certain devices and combinations thereof, for nailing, and fastening, heels to shoes; and for holding the heel in'any desired position while the edge is finished and the paste, cement, or glue, between the lifts and on the sole, is drying.

One part of Fig. 1 represents an apparatus for centering, and punching a hole through, the heel of a shoe, for the reception of a screw, as described in the patent of Stillman and Vesley Thorp, granted January 25th, 1859. The punch, 8, is fast in the vertical post, 1. The centering arms, 4, 5, 6, shaped as shown in the drawing, are pivoted at their lower extremities to the adjustable yoke, 2, which may be raised or lowered, as required, and held in place by the set-screw, 3. These centering arms pass freely through slots in the yoke, 7, which, having a hole through its center, slides up and down on the post, 1. The heel, to be centered and punched, is placed on over the punch, 8, the hind end of the shoe resting against arm, 6; the sliding yoke, 7, is now raised by the hand until it brings the arms, 4i and 5, against the sides of the heel, when the punch, 8, will be under the center of the heel and ready to receive a blow, or pressure, from any suitable instrument, for the purpose of punching a hole through the sole.

A is an upright post of iron attached to a table or bench, in any suitable manner.

B is a piece of cast iron shaped as seen'in Fig. 1; the part, B, being a cylinder with a hole, g, passing through its center.

(a is a bolt passing through the upper end of post, A, and screwing into B, so that the latter may be rotated on .it as an C is another piece of cast iron shaped as represented in the figure; the upper extremity being a hollow cylinder through which passes the cylinder, B. C is drawn down by means of the spring and bolt, 0, the latter screwing into it, as represented by the dotted lines.

dis a pin passing freely "through B and into C, its lower extremity resting on the top of the lever, D, which is pivoted at m to bolt, 1, so that by raising the end of said lever the piece, C, will be forced up.

f f f are steel plungers a little larger than the nails commonly used for attaching heels to shoes, and long enough to pass up through corresponding holes, 7'', in the lower heel-bed, F, a top-view of which is shown in Fig. 3. The lower part of F is cylindrical and made enough smaller than B to enter and turn with freedom in it.

G is a disk of rubber, or other elastic material, attached to the top of F, so as to yield it, and thereby give all parts an equal or suflicient bearing and pressure.

E (Figs. 1 and 3) is a thin steel slide, the size of F, and attached by its under side to a thimble which passes over the cylindrical part of F. Through this slide are holes corresponding to the holes, f, in F. Thus, when the slide is turned a little, as represented by the dotted lines in Fig. 3, so that it rests against F, the bottoms of the holes, f, in F, will be covered, and the nails, which are placed in them previous to being forced into the heel, will not drop through, until the bed, F, is turned so that the plungers, I, will be directly under them; the slide is then turned until the shoulder, it, touches F, and the prong, an, strikes against the guide pin, 6 (F 1), when the holes in E and F will be in the same vertical lines and ready to receive the plungers, f.

H is a round hollow shaft playing through bearings in B, the lower extremity resting on the spiral spring, J, and thrown up by it, as represented in the drawing. The upper end of 11 passes through arm, K, which is kept in place by set-screw, R.

I is an iron rod passing through H; the lower end of said rod being pivoted to lever, D, and the upper end provided with a nut, 2', by means of which K is rendered adjustable, and heel-bed, O, brought nearer to, or farther from, heelbed, F, to accommodate heels of different thickness.

O is the upper rotary heel-bed, shaped as shown in Fig. 2, and prevented from dropping out of arm, K, by screw pin, S, and groove, 8. Through this bed, as represented in Fig. 2, are holes, P, into which the nails are put to be forced into the heel by means of the plungers, P.

M is a curved piece of iron, or steel, in which the plungers, P, are fastened, to enter theholes, P, in the rotary bed, O.

M is a pin passing freely through arm, K, its lower extremity being fast in M.

n is a flat spring for supporting and raising the plungers, P.

L is a lever pivoted at Z to arm, K, its fulcrum being the top of pin, l\ by means of which lever the plungers, P, are depressed through the holes in O and the nails forced into the heel of the shoe.

u is a pin projecting a little from the side of O, so that when the latter is turned (after the nails are dropped in the holes, P) until it (u) strikes against the piece, M, the plungers will be directly overthe holes.

Through the center of O is a hole, g,- c] being a similar hole through the center of F. Into these holes, 9 and g, pins may be inserted, if desired whose projecting ends may operate as a holder, or guide, to the nut and screw which are used for confining heels, as described .in the patent of Stillman and lVesley Thorp, keeping said nut and screw in place while the heel is being adjusted between them.

Arm, K, being turned to one side, and slide, E, being also turned so that the nails will not drop through, the nails are inserted, points up, in the holes, f. Bed, F, is. then turned so that the holes shall be directly over the plungers, f, after which the slide, E, is turned back so that the holes in it shall be directly over the holes in F,-shoulder, h, prong w, and pin t, operating as guides. The shoe, with the bottom up, and the heel placed on, is then put over the bed, F. Arm, K, is then swung back so as to be in the right position over the heel. Rotary bed, O, is then turned so that the nails, point down, can be dropped into the holes, P. O is then turned back so that the plungers, P, shall be directly over the holes, P. The heel is now between the two beds, 0 and F; and by raising lever D, the plungers, 7, will force the nails into the heel on the inside; and by depressing lever, L, the plungers, P, will force the nails into the top of the heel. The heel is now, by these operations, compressed between the two beds, O and F, and as these beds can be turned to the right or left, and as the whole frame, '13, with all its appendages, can also be turned 011 its axis, a, it follows that the shoe can be put in any position desired for finishing the edges of the heel, while, at the same time, the machine is pressing the "lifts together and on the sole, and the glue, or paste, are setting or drying.

What I claim as my invention and desire to secure by Letters Patent, is

1. The rotary heel-bed, O, provided with the nail holes, P, and operating, as described, in combination with the plungers, P, and arm, M, or its equivalent, for the objects specified.

2. The combination and arrangement of the adjustable swinging arm, K, shaft H, frame B, spring J, and connecting rod 1, substantially as, and for the purposes, described.

3. The combination and arrangement, substantially as described, of the rotary heel-beds, O and F, rotating frame B, arm K, and lever D, for the purpose of compressing the lifts and sole, and holding the heel in any desired position for finishing the edge.

4. The use of the rubber, or elastic cushion, G, as, and for the purpose, set forth.

5. In combination with the punch, 8, the centering arms 4, 5, 6, sliding yoke 7, and adjustable yoke 2, substantially as described and for the object specified.
