RUBBER HEEL.

Application filed October 13, 1927.

This invention relates particularly to that type of rubber heels now commonly in use on shoes and other footwear.

It is a matter of common knowledge and experience that the rubber heel as heretofore provided, secures to the user the required resiliency but is unsafe on wet Walks because of its tendency to slip thereon.

It is the object of the present invention to provide a ruober heel of the character indicated that is so constructed and arranged as to effectually prevent slipping on wet surfaces without materially interfering with its natural resiliency.

It is also an object of the invention to provide a heel of the character indicated that will he economical to manufacture, simple in construction, durable, and highly efiicient in its practical application.

Figure l is a plan view of the bottom of a rubber heel embodying my invention.

Figure 2 is a plan view of the upper side of a rubber heel embodying my invention, part broken away.

Figure 3 is a section on line 3-3 of Figure 1.

Referring now more particularly to the drawing, I show at 1 a rubber heel having the general conformation of heels of this type, the wearing surface being indicated at 2. The side of the heel opposite to the surface 2 is recessed a distance as indicated at 3, and the usual provision for nailing the heel to the shoe is shown at 4-.

In affecting my invention I first form a number of holes in the heel 1 extending through from one side to the other. These holes 5 may be of any suitable dimensions and arranged. in any suitable manner throughout a greater or lesser portion of the heel. In each hole 5 is inserted a peg 6. This peg 6 is preferably ofleatherv or some similar material that is tough and somewhat Serial No. 226,010.

elastic, and that will not slide easily on a smooth wet surface such as a cement sidewalk. In the drawing I have shown the peg extending slightly beyond the wearing face 2 of the heel 1, as the best results appear to be obtained by slightly projecting the peg in this manner. The end of the peg opposite to the wearing surface is provided with "a head as 7 lying in the recess '3, this head effectually preventing the peg from working out of the hole in which it is placed. After all the pegs are in placethe recess 3 is substantially filled with rubber and the rubber vulcanized, or any suitable filler may be used.

The result of this construction is, that 0 when the heel is in use the leather pegs 6 are prevented from being pushed out of their several holes by the backing 8 on heads 7 and the foundation 9 of the heel upon which the rubber heel 1 is mounted. hen the rub- 5 her heel l is compressed, therefore, the leather pegs are brought into direct contact with the surface being walked over, and yet they are of such a nature that they will give somewhat under the pressure and so the necessary tract-ion tc prevent slipping is secured and at the same time the full resiliency of the heel is maintained;

It is to be understood, of course, that any material or substance having the required characteristics may be used, and held in place in any suitable manner.

I claim:

A rubber heel of the character described, having a wearing surface formed on one side thereof and a recess formed in the other surface thereof and having orifices formed therein conmiunicating with said recess and wearing surface, a leather peg positioned in each orifice and provided'with a head seated .8 in said recess, and a covering for the heads of the several pegs.
