\ RUBBER' HEEL Filed Feb. 9,v 1940 attorney Patented Juiyl, 1940 RUBBER HEELy Agostina Santacroce and Anthony Milshow,

Cleveland, -hio Application February 9, 1940, Serial No. 318,040 s claims. (ci. scf-a) Our invention relates to rubber heels and in particular to an improved vacuum type of heel having a recessed 'center and a slope therein tapered toward itslower end, andhavng for its 5 main object a cushioning effect whereby the` vacuum formed within the recessed center expels air with each step, thus preventing slipping on ice, snow or wet slippery surfaces.

Another object is to provide a cushioning effect f and means `for expelling stones and other objects from the recessed center of the h eel.

These and other objects may be seen and noted from the following specification and its accompanying illustration in which- Fig. 1 is a top plan view of the heel showing the reinforcing fabric and the outer horseshoe shaped tapered rim.

Fig. 2 is a bottom plan View of the heel showing the tapered recess therein.

Fig. 3 is a sectional view on lines 3-3 oi.' Fig. 2. Fig. 4 is a section on lines 4-4 of Fig. l. Y Fig 5 is a perspective view of the bottom surface showing the suction cups and tapered recess.

Fig. 6 is a fragmentary section of the heel se' cured to footwear.

Again referring to the illustrations, the rubber heel I0 may be a molded form, preferably as shown, in a horseshoe shape, an'd the inwardly inclined rim I I 'may be substantially of the same width around the periphery thereof, forming a concave top surface.

A dat center portion I2 has secured thereon a reinforcing fabric I3 within the inner periphery spaced as showninFig. 5.

The heel lwhen secured to suitable footwear will flatten against the heel surface I1 of the said footwear which causes the outer top periphery, of the heel I0, to expand creating a tapered outer edge lila between the top' and bottom peripheries of said heel.

This tapered edge .lila increases the resiliency and creates a greater vacuum within the tapered recess I4 due to the inward pressure of the tapered outer edge I0a against the outward pressure of the inner walls Ida at each tread which l T forces air or-any small substance to be expelled from within the recess I4.

This action prevents slipping when streets are lcy or slippery from any cause, and promotes greater safety when walking.

We claim:

.1. A' rubber heel having a recess in the tread face thereof, and a rim around the backand sides of the recess, the tread surface of the rim being inclined inwardly from its outer edge to said recess, and the bottom surface of the recess being inclined upwardly and forwardly from the rear part of the rim to the front of the heel.

2. A rubber heel having a recess in the tread face thereof, and a rim around the back and sides of the recess, the tread surface of the rim being inclined inwardly from its outer edge to said recess, and the bottom surface of the recess being inclined upwardly and forwardly from the rear partof the rim to the front of the heel, the top surface of the heel 'being concave and provided with a fabric reinforcement secured to said surface in the concavity. 4

3. A rubber heel having a recess in the tread face thereof, and a rim around the back and sides of the recess, the tread surface of the rim being inclined inwardly from its outer edge tc said recess, and the bottom surface of the recess being inclined upwardly and forwardly from the rear part of the rim to the front of the heel, the rear part of the tread rim having suction cups formed therein.
