DETACI-IABLE RUBBER HEEL FOR SHOES.

Application filed May 26,

T 0 aZZ whomz't may concern Be it known that I, SAM Dow, a subject of Syria, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented new and useful Improvements in Detachable Rubber Heels for Shoes, of which the following is a specification.

This invention relates to heels for boots and shoes and is especially adapted for use in connection with heels, the body portion of which is made of wood or metal.

The object of the invention is to provide a tread for the heel of a boot or shoe which can be easily attached to or detached from thebody portion of the heel of the shoe without the use of nails or without the use of adhesive material of any kind and which, when at tached to the body portion of the heel, cannot become accidentally detached therefrom, but which can be so manipulated as to become detached by hand for the purpose of attaching a new tread to the bottom portion of the heel when said tread has become worn or otherwise injured.

The invention consists in a heel with a resilient tread and means for detachably attaching the tread to the heel as hereinafter set forth in the specification and particularly pointed out in the claim.

Referring to the drawings:

Figure 1 is a side elevation, partly in section. of my improved heel.

F ig. 2 is an end elevation of the same broken away and partly in section on line 2-2 of Fig. 1.

Fig. 3 is a sectional elevation similar to Fig. 1 illustrating the manner in which the parts are positioned when the tread is being attached to the heel.

Fig. 4: is a sectional elevation similar to Fig. 1 showing the relative positions of the parts when the tread is being detached from the heel.

Fig. 5 is a detail plan view of the dovetailed slide plate whereby the tread is attached to the body portion of the heel.

Fig. 6 is a detail plan view of the plate Which is molded in the tread and is slidable upon the dove-tailed plate illustrated in Fig. 5.

Like numerals refer to like parts throughout the several views of the drawings.

In the drawings, 8 is the body portion of the heel which may be made of wood, aluminum or any suitable material. A slide plate 9 is fastened by a screw 10 to the bottom of Specification of Letters Patent.

Patented Nov. 22, 1921. 1920. Serial No. 384,299.

the body portion 8, this beveled edges 11 which are beveled downwardly and outwardly from the bottom surface of the body portion 8. 12 is the tread of the heel made of resilient material, pref erably rubber, and in this tread is embedded a plate 13 which has flanges 1-1- on its upper surface inclined toward each other and adapted to slide upon the beveled edges 11 of theslide plate 9. The plate 13 extends on its opposite sides beyond the flanges 14 within the rubber tread 12, whereby it is anchored in said tread.

It will be noted that the upper edges of the flanges 14 are flush with the upper surface of the tread l2.

The tread is attached to the shoe by tipping it at an angle, as illustrated in Fig. 8, and pressing the upper surface of the tread adjacent the rear portion thereof against the bottom of the body portion of the heel and against the bottom of the slide plate 9 to compress that portion of the tread suiiiciently to allow the plate 13 to engage the slide plate 9 and the flanges 14 thereon to be brought into alinement with the beveled edges 11, whereupon the tread is slipped upon the body portion of the heel with the plate 13 sliding on the slide plate 9 and the flanges 1a engaging the beveled edges 11 of the slide plate 9.

When the tread has been pushed along the bottom of the heel from the breast of the heel toward the back of the heel to the position illustrated in Fig. 1, it will be seen that the tread is locked against movement across the heel by the flanges 14: and slide plate 9. It will also be seen that it is locked against movement longitudinally of the heel and longitudinally of the slide plate 9 by the portions 15 and 15 of the tread, each of which is in horizontalalinement with the slide plate 9, and, therefore, the tread will be locked to the body portion of the heel against longitudinal movement relatively to the slide plate 9, as well as against movement across the heel. In removing the tread from the body portion of the heel, the portion 15 of the tread is bent downwardly either by hand or by inserting a thin metal piece such as a screw-driver between the top of the portion 15 of the tread and the bottom of the body portion of the heel at the rear thereof, thus causing the tread to as sume the position illustrated in Fig. 4E, whereupon the tread may be removed from slide plate having Q 1 said inngerforadz-e plateand said imperforate plate having a pair of parallel flanges inclined toward each other andadapted to slide upon said slide plate and engage said parallel sides, the upper edges of said flanges being substantially flush with the upper face of said tread, said plates being prevented by the engagement of said shoulders with the opposite ends of said slide plate from relative movement longitudinally thereof when the parts are assembled.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses. V

SAM DOW.
