DETACHABLE RUBBER 'HEEL.

Specification of Letters Patent.

Patented Feb. 25, 1913.

Application filed April 29. 1912. Serial No. 693,983.

To all whom it may concern:

Be it known that I, JUNIUs E. SHELL, a citizen of the United States of America, residin at Lenoir, in the county of Caldwell and tate of North Carolina, have invented certain new and useful Improvements in Detachable Rubber Heels, of which the following is a specification.

This invention relates to detachable rubber heels and one of the principal objects of the invention is to provide a rubber heel which may be readily attached to any shoe.

Another object of m invention is to provide a rubber heel w ich may be readily attached to a heel by means of screws. and which will not become accidentally detached.

These and other objects may be attained by means of the construction illustrated and shown in the accompanying drawings,

in which Figure 1 is a longitudinal section throughthe line 3-3 of Fig. 2.

Referring to the drawing, as shown in Fig. 1, the rubber heel is attached to a shoe constructed in the ordinary manner. The rubber-heel 1 has molded into it a short distance from the upper surface a metal plate 2. This plate has transverse slots 3 therein and these slots are beveled as indicated at 4, the'narrowest portion of the slots being at the top of the plate and the widest ortion being at the bottom. The outer e ges of the plate are provided with two rows of staggered projections 5, the projections in the lower row alternating with the projections in the upper row, the top surface of the upper projections being flush with the top surface of the plate and the lower surfaces of the rojections in the lower row being flush with the lower surface of the plate, said projections in the upper and lower rows havin their inner surfaces slightly convex and slanting toward the central line of the edges of the plate.

It is seen by this construction, that the plate is solidly and securely embedded in the rubber heel and will not readily become detached therefrom. As indicated in Fig. 2, the heel plate is provided with four perforations 6 which are screw threaded to receive flat headed screws7, and the rubber heel itself is provided with circular recesses extending from the upper surface of the heel to the erforations in the plate, these v recesses alining with the perforations in the plate and being slightly larger than those perforations.

In practice, the screws 7 are countersunk 1n the inner sole 8 of the shoe, the inner sole being covered at the heel by the usual inner pad 9. When it is desired to remove the heel because of wear or for any other purpose, the inner pad 9 is first removed and then the screws 7 are unscrewed from the plate 2 and the heel is removed. A new heel may be put in its place by simply inserting the screws 7 in the perforations in the rub ber heel and then screwing the screws 7 into the perforations provided for them in the heel plate 2.

My invention is of simple construction, can be manufactured at a low cost and is very eflicient for its purpose.

I claim:

1. A detachable rubber heel provided with a metal plate, said plate being em-' bedded in the heel a short distance from the upper surface thereof, said plate provided with slots therein, said slots having their surfaces beveled, said plate rovided on its outer edges with two rows 0 staggered projections, the projections in the lower row alternating w1tl1 the projections in the upper row, said plate prov ded with threaded perforations to receive screws provided in the heel portion of the shoe, sald screws being adapted to engage the perforations in the plate for holding the heel in place.

2. A rubber heel having a metal plate embedded therein said metal plate provided with transverse grooves, said plate having its outer edges provided with staggered projections, and means for attaching the rubber heel to the 'heel portion of the shoe.

3. A detachable rubber heel for shoes or boots, said .heel having a metal plate embedded therein at a slight distance from the upper edge thereof, said plate provided with transverse grooves therein, said grooves having their surfaces beveled, the up er edges of the grooves being closer toget er than the lower edges thereof, said plate having its outer edge provided'with two rows of staggered projections, the-projections in the lower row alternating with the projections in the upper row, said projections in plate provided with threaded perforations therein, said rubber heel provided with recesses alining with said perforations, said recesses extending from the upper surface of the rubber heel to the metal plate to permit the insertion of flat headed screws passing through the inner sole of the shoe or boot, said screws being alined with the recesses in the rubber heel and the perforations in the metal plate and being adapted to be threaded into the said perforations in the plate to hold the rubber heel in place.

In testimony whereof I afiix my signature in presence of two witnesses.
