DETACHABLE HEEL.

SPECIFICATION forming part of Letters Patent No. 787,306, dated April 11, 1905. Application filed February 10, 1904:. Serial No. 192.980-

T!) lllllilH it Ill/M l] WWI/Peru.-

Be it known that l. FRANK B. Moss, a citizen of the l nitcd States, and a resident of Denver. in the county of Denver and State of oloiadohave invented a new and useful lnii provement in Detachable lleels, of which the i following is a specification.

My invention relates to an improvement in detachable and intei'chaiigcable heels.

The object of this invention is to provide a device which will act as a support for bracing and strengthening shoes and at the same time provide simple means for conveniently replacing worn heels at small expense without the necessity of going to a shop to have it done. ln other words, the invention has in view the provision ofheels as independent articles of manufacture, such heels having means connected therewith for quickly, easily, and accurately fastening them to a shoe and for detaching them when occasion for removing a worn heel arises.

My invention consists in certain novel features of construction and combinations of parts, which will be hereinafter described, and pointed out in the claims.

in the accompanying drawings, Figure 1 a bottom view of the heel-plate. Fig. 2 is a section of the same. Fig. 3 is a view of the interior of my improved form of locking-plate in its prcfcrred construction. Fig. 4 is a section through the heel and locking plates.

Figs. o, 7. s, E). 10, and ll are views of i slightly-modilied forms of locking plate, and locking mechanism more particularly; and Fig. 12 is a detail view of the screw 26.

A represents a heel-plate made in the form r of the usual heel of a boot or shoe and adapted to be secured to the heel portion of the solo in any approved manner. This plate is preferably provided at or near its center with a loop. or it might be a hook l,preferably diagonallv placed, as shown in Figs. 1 and 3.

.llikewise the heel-plate is preferably furnished with several holes 2 2 -say threearranged triangularly. The purpose of the loop orhook and the holes will presently be explained.

B indicates the locking-plate, which in the various forms is the same in outline, it being made to conform in shape to plate A, which it fits. The heel forms a part of or is secured to this locking-plate B in any approved manner. The locking-plate has a chambered-out interior 3, or it may be made of two outer plates spaced apart by suitable filling-blocks at the edges and riveted or otherwise secured together.

A locking-lever ii is pivoted at one end in the chamber 3, and this lever is provided with I a tongue -t, preferably curved in the arc of a circle from the pivot of the lever as a center. This tongue mayhave a cam or tapering outer surface, if desired. and is adapted to enter the loop or hook l and draw the locking-plate sei curely against the heelplate, whereby to attach the heel rigidly to the boot or shoe. A thuiiibpiece 5, connected with the free end i of the lever L, is adapted to be manipulated to force the tongue 4 in or out of the loop or i hook. The outward movement of the lever is limited by the wall 6 of the chamber and the inner movement by the thumb-piece 5, i which when forced inward onlyprotrudes sufficiently to afford a means of operating theley ver and hardly enough to be visible, it being on the inside or iorward edge of the heel. Dowelpins '7 7 project upwardly from the l lockingplatc at positions apart correspondi ing to the holes 2 2 in the heel-plate A, they 1 being adapted to enter said holes and insure the right position of the heel when attached. These dowel-pins hold the detachable heel against lateral movement or any tendency to twist, and the locking-lever secures the heel to the heel-plate. Obviously the holes 2 2 and pins 7 7 might be transposed. This is likewise true, of course, of the other parts of the lock.

Various modiiications might be made, some of which I have illustrated. For iiistance, in Fig. the loop 1 instead of eX tending diagonally is disposed transversely and slide-plate ll), provided with an elony gated slot 1 1, held by a pin 12, is arranged to slide LlKlWlSC or lengthwise of the heel into the loop, the outer end 13 of the plate being in the form of a thumb-piece, by which i the plate is manipulated.

Fig. 6 illustrates a form very similar to that shown in Fig. 3. In Fig. 7 this idea is slightly modified, the plate 14 being confined within the chamber of the locking-plate B, and a lever 15, pivoted at 16, has a thumb-piece 17 pivoted to its free end and extended out through the forward edge of the heel in position to be pushed in or out to force the tongue 14 in or out of the loop 1.

In Fig. 8 an open hook 1 is provided in lieu of the loop, and a hand-lever 18 is pivoted at 19 and carries a segment 20 at the inner end, adapted to be turned beneath the hlook, whereby to lock the heel to the heelp ate.

In the modified construction shown in Fig. 9 a crank-shaft 21 is pivoted in bearings 22 22 and provided with an angular outer end 23, adapted to receive a key, whereby the crank portion 24 is turned or rocked beneath the hook 25.

In the construction illustrated in Fig. 10 a screw 26 is provided with a pinion 27, which is turned by a gear-wheel 28, a portion of the teeth of which are accessible from the forward edge of the heel where it is turned, the screw taking into screw-thread formed in the heel-plate secured to the heel portion of the sole.

In Fi 11 the screw is provided with a worm-w1eel 29, operated by a worm 30 on shaft 31, the outer end 32 of which is constructed to receive a key. A heel provided with any one of these attachments may be quickly applied or removed when occasion 3 may require it, either to attach a new heel or remove a heel already applied.

In addition to the forms described various other slight changes might be resorted to in the form and arrangement of the several 4 parts described without departing from the spirit and scope ofmy invention, and hence I do not wish to limit myself to the precise constructions herein set forth; but,

Having fully described my invention, what 4 I claim as new, and desire to secure by Letters Patent, is-

1. The combination with a heel-plate, of a chambered-out fastening-plate, one having pins and the other holes to receive said pins, 5 and locking means, a part of which is connected with each plate, said locking means independent of the pins.

2. The combination with a heel-plate having a centrally-located fastening means, of a 5 chambered-out fastening-plate, having looking mechanism thereon, one of the plates being provided with pins and the other with holes for the reception of the pins, said locking mechanism engaging and fastening the heel 6 to the said centrally located locking means.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

FRANK B. MOSS.
