HEEL FOB BOOTS OR SHOES.

Application filed November 18, 1926. Serial No.149203.

The invention relates to improvements in heels for boots or shoes and an object of the invention is to provide a heel which can be readily attached to the shoe and which pre sents a tread face having the desirable wearing qualities and embodies also a particular- 1y resilient portion interposed between the tread face and the shoe, such structure providing a heel which will wear for an indefinite period. and which Will absorb to a marked degree the jar occasioned in walking.

With the above more important object in view, the invention consists essentially in the arrangement and construction of parts hereinafter more particularly described, reference being had to the accompanying drawing, in which Fig. 1 is a side view of a shoe equipped with my heel.

Fig. 2 is an enlarged detailed vertical sectional view longitudinally through the heel. V

In the drawing like characters of reference indicate corresponding parts in the several figures.

The heel which I provide presents a tread face of suflicient hardness to effectively withstand the wear to which the heel is subjected and between this tread face and the shoe. 1 interpose a layer of material having desir able resilient qualities so that the heel as a whole will wear indefinitely and possesses a cushioning effect very desirable to, the

wearer.

In Figure 2 I have shown the heel 1 as formed from an outer tread layer or portion 2 of wear resisting hard rubber as ordinarily employed in rubber heels. an inner layer or portion 3 of similar rubber and an intermediate layer or portion 4 of softer and more resilient rubber. the various port ons being firmly cemented together as indicated at 5 and 6. The layer 2 is made so that it will withstand the wear to which it is subjected whilst the layer 4 provides a cushioning effect which is very desirable as it absorbs the shock to which the heel is subjected.

Nail holes 7 are provided in the heel as is usual and the heel is fastened to the sole8 of the shoe by nails 9. Here it will be 'observed that washers 10 are imbedded in the heel between the layers 3 and 4 thereof and located at the inner ends of the holes 7 and that the nails are driven in through the washers. As the driven nails engage the washers which are seated on the inner layer 3 of the heel. they effectively hold the heel to the shoe and do not in any way interfere with the resilient qualities of the interposed layer 4 thereof. I

What I claim asrmy invention is A unitary rubber heel adapted to be attached as a unit to a shoe comprising inner and outer layers of comparatively hard rubber and an interposed layer OfCOHlPEII'ZttlVQ- ly soft, cushioning rubberceinented thereto, there being suitably disposed nail holes passing through the outer and intermediate rubber layers and anchoring nail receiving washers imbedded in the heel between the inner and intermediate rubber layers and s noted at the upper ends of the holes.
