RUBBER HEEL.

Application filed March l, 192s. Serial No. 92,225.

This invention relates to improvements in. It will be noted that there is a'small porrubber heels and the like for footwear.

An object of this invention'is to provide an improved rubber heel having a relatively hard or metallicinsertion,therein, which will tend to, cause the heel tofwear evenly. The improved; rubber heel with the insertion is so designed that the heel will not wear quicker on one side than on another,

and is especially advantageous where the rubber heel is so formed as by having a suction cup or the like formed upon its tread surface, reducing the size of the tread surface adjacent the rear of the heel.

With the foregoing and other objects in view which will be mademanifest in the following detailed description and specifically pointed out in the appended claim, reference is had tothe accompanying drawings for an illustrative embodiment of the in vention, wherein: I Q

. Figure 1 is a topplan. view of the improved heel,

r Fig. 2 is a vertical section taken on th I line 22 of Fig.1, and

Fig. 3 is a bottom plan view of the heel showing the tread surface.

Referring to the accompanying drawings wherein similar reference characters designate similar parts throughout, the improved heel consists of a heel-shaped body 10 form-.

ed of rubber or of similar composition. On the under side of the heel there is formed a concavit 11 formin a suction on or the like. The concavity or suction cup 11 is used for illustrative purposes only, and it will be readily appreciated that in some instanees this cup can be omitted entirely. Where the suction cup is employed, the

tread surface of the heel, indicated at 12, is

I materially reduced and the heel unless otherwise protected is very apt to wearon one side faster than on another. As .a means for protecting against this disadvantage, a metallic insertion 13 is imbedded in the heel. This metallic insertion is preferably formed of corrugated sheet metal of general U-' shaped form and is arranged approximately aarallel to the rear sides of the heel. Its

ottom edge is substantially flush with the tread surface 12, as clearly shown in Fig. 2, while the top of the insertion is disposed be low the top surface ofthe heel. By this construction the metallic insertion being'of relatively hard material tends to keep the heel even during Wear. r I g evenly.

tion of rubber betweenthe top of the insertion 13 and the top surface of the heel, and this affords a limited resiliencyor spring for the insertion when the Weight is placed upon the heel. The purpose of using corrugated ArEN- OFFICE.

metal is for the reason that corrugated metal cannot easily loosen and drop out of the heel, especially in view of the fact that it is molded in the body of the heel. Furthermore, it presents an edge which is distributed overa considerable area, making the insertion very effective.

, By the improved construction it Will be readily appreciated that the improved heel I is very advanta eous in that it protects and strengthens ru ber heels, having limited tread surfaces, preventing the heels from wearing quicker in some portions than in.

others and tending to keep the heel Wearing pression formed in its bottom surface centrally'of the heel, defining a semi-circular wall adjacent the rear of the heel and a flat portion adjacent the'front of the heel, a

insertion embedded in, and I sheet metal molded inthe heel to prevent said semicircular Wall portion from Wearing, and to reinforce the same to prevent caving in thereof, said insertion extending generally aboutthe back'of the heel centrally between the back edge of the heel and the cup-shaped depression, and having its width extend upwardly from the bottom of said wall, said insertion being corrugated to offer the maximum wearing surface to the ground, the bottom surface of the heel being flush with. the bottom edge of the insertionand said insertion extending into the Wall a distance considerably less than the thickness of said heel, whereby the presence of said insertion in said heel, will detract little from the resiliency of said heel. I p

In testimony whereof I have signed my name to this specification.
