Description

Patented Feb. 25, 1936 UNITED STATES PATENT OFFICE 1 Claim.

My invention relates to the shoe industry, and particularly to rubber heels for use on shoes of various kinds.

One of the drawbacks of rubber heels is that they become readily worn on the lower face thereof and particularly at the rear of the heel.

It is an object of my invention to provide a rubber heel which will be so reinforced as to substantially lengthen the life of the heel by preventing the quick wearing of the heel at the rear edge thereof.

The manner of accomplishing the foregoing object as well as further objects and advantages will be made manifest in the following description taken in connection with the accompanying drawing, in which:

Fig. 1 is a bottom plan view of the preferred embodiment of the heel of my invention.

Fig. 2 is a vertical sectional view taken on the line 2-2 of Fig. 1.

Fig. 3 is a view similar to Fig. 2 illustrating the heel of my invention applied toa shoe.

Fig. 4 is a perspective view of the reinforcing member of my invention.

Fig. 5 is a rear view of the heel shown in Fig. 1 mounted on a shoe.

Referring specifically to the drawing, the rubber heel 10 of my invention is shown as including a body of rubber I l of the usual shape, this body having a number of nail holes l2 formed therein, each of these holes having a washer l3 embedded in the rubber body ll around the hole adjacent its lower end. Also formed in the rubber body II are nail holes 14. Surrounding each of the holes I4 is one of a pair of ears l5 which are shaped identically like the washers I3, but which are embodied in a reinforcing member I6 including an arcuate plate I'I provided with legs l8 which integrally connect the plate I! with the washer-like ears l5.

Permanently secured upon the lower or wearing face IQ of the plate 11 is a facing 20 of extremely hard material such as tungsten carbide or the like. The heels H] are preferably in right and left styles, the heel as shown being for a left shoe as the reinforcing members 16 are preferably located on the rear outer edge of the heel.

In the manufacture of the rubber heel ID the washers l3 and the reinforcing member I6 are all held in place in the mold by suitable fixtures on the mold and the rubber forced around these elements so as to fill the mold. This results in the washers 13 being embedded deep inthe rubber and the reinforcing member I6 is also embedded therein excepting that the plate I! and its facing 20 are disclosed at the rear edge of the heel as clearly shown in Fig. 1.

In applying the rubber heel ID to the shoe 25 as shown in Fig. 3 suitable nails 26 are driven into the holes I2 and 14 so as to pass through the washers I3 and ears l5 and into the sole of the shoev 25. The heel I0 is thus securely fastened to the shoe and the member 16 is at the same time anchored by the nails 26 to the shoe.

In using the heel ID of my invention it is found that although the member [6 is formed of metal no noise is caused by walking on this heel. This is believed to result from the fact that the member is cushioned from the shoe 25 on which the heel is shown applied in Figs. 3 and 5 by a considerable portion of the rubber body II which is disposed between the member I6 and the shoe 25.

It is thus seen that I have produced a rubber heel which will have a much longer life than 5 rubber heels in general use yet without reducing my invention which also should be pointed out is the protection of the heel from wearing by the member IS without diminishing the resiliency of the heel itself. It is of course evident that the member l6 by protecting the rear edge of the heel insures that the original resiliency of the rubber heel will be maintained until the member l6 has been worn away, thus greatly increasing the effective life of the heel.

What I claim is:

In a rubber heel the combination of: a rubber heel body, having an upper attaching face and a lower wearing face, and nail holes formed in said wearing face spaced inwardly substantially equal distances from the outer edge of said body; washers embedded in said body about said nail holes; a block of metal embedded in said body to conform with a portion of the rear outer edge of said body to one side of the center of said body and having its lowermost surface lying in the plane of said wearing face, said block at its ends overlapping an adjacent pair of said Washers; and means for connecting said block to said washers.
