BLUFORD W. BROCKE'I'T, OF CLEVELAND, OHIO.

EESILIENT HEEL.

Application filed May 27, 1918.

To all whom'z't may concern:

Be it known that I, BLUFORD W. Bnooxn'rr, citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Resilient Heels, of which the following'is a. specification.

This invention relates to resilient heels,

such as are used upon shoes and other footwear.

The object of the invention is to provide 1 an improved resilient heel which clings to the pavement or other surface being walked upon and therefore protects the wearer from injuries which otherwise *might be caused by slipping or skidding of the heel. More particularly the inventlon has for its object to provide a heel of this kind having transversely extending teeth or ridges which are so arranged as to resist slipping movement of the heel both forwardly and toward either side, which are self-cleaning, or in other words, which automatically free themselves from material scraped from the pavement, and which heel is also. more strongly reinforced against wear at its rear portion than prior heels of the same general type.

Further objects of the invention are in art obvious and in part will appear more in detail hereinafter.

In the drawings, which represent one suitable embodiment of the invention, Figure 1 is a bottom plan *viewtFig. 2' is a side elevation; and Fig. 3 is a perspective view from beneath. i

For purposes of illustration the drawings show the invention applied to a heel adapted to be secured to or embodied in the heel of a shoe. It comprises a body portion 1 which may be made of rubber, a rubber composition, or any other suitable resilient material. and which is provided with a series of openings '2 through which may be driven nails or screws for securing it to the shoe. The lower surface of said heel is suitably formed to provide a series of 'transverselv extending saw-teeth 3 which in number will vary with the size of the heel and with the particular effect to be obtained. The drawings show four teeth or projections. of which the first or the'one at the front of the heel has its front surface 4 formed by the vertical surface at the front of the heel, while the last saw-tooth has its bottom surface 5 in a horizontal plane substantially co-incident with the sharp edges 6 of the remain- Specification of Letters Patent.

ing teeth. The first three teeth toward the front have their back surfaces 7 sloping on a long .gradual incline downwardly toward the front of the heel, where said surfaces intersect along the edges 6 the front surfaces 8 of said teeth, which may be vertical but are shown as slightly inclined downwardly from the rear toward the front, so that the angle between the

surfaces

7 and 8 is slightly less than a right angle. This makes the edges 6 relatively sharp so that they exert a squeegee effect on the pavement and cut through and-wipe off water, mud or any other foreign material lying upon the pavement, and therefore cling or stick to the erally and meeting along the center line of the heel in a sharp point or projection 9. When the heel is planted upon the pavement the inherent resilienc of the material causes these points or projections to bend downwardly into close or intimate contact with the surface walked upon. Moreover, each e observed that the teeth or pro' 1 Each tooth or projec half of each tooth has a sort of plow action,

as any material which it may scrape up from the pavement slides along-the. channel in front of the tooth and is discharged at the side of the heel. In other words, the

teeth are self-cleaning and not likely to be-.

come clogged with material such as would otherwise interfere with their sqneegeeaction. Finally, the lateral inclination of said teeth increases the area of the horizontal surface 5 at the rear of the heel over what it would be if the teeth extended straight across'the heel, and thereby forms a wide fiat pad of solid material at the rear of the heel which materially increases its wear re.

sisting ability. This pad always receives the first impact of planting the heel upon the pavement, so that reinforcement at this point is of material advantage.

What I claim is:

1. A heel, comprising a body portion of yielding material having its lower portion provided with a series of ridges extending transversely of the heel and each diagonally disposed to the longitudinal axis of the heel, said ridges having a relatively long face sloping forwardly and downwardly and intersecting along a sharp edge a relatively short face lying in a substantially vertical plane, thereby forming a series of saw-teeth having sharp edges which contact the pavement and exert a squeegee efi'ect to prevent slipping of the heel thereon.

2. A heel, comprising a body portion of yielding material having. its lower portion provided with a series of ridges extending laterally and rearwardly toward the sides of the heel from a longitudinal line, said ridges havin a relatively long face sloping for- ,wardly and downwardly and intersecting along a" sharp edge a relatively short face lying in a substantially vertical plane, thereloy forming a series of saw-teeth having sharp edges-which contact the pavement and having sharp edges which contact the paveanent and exert a squeegee efi'ect to prevent slipping of the heel thereon. o

In testimony whereof. I affix my si ature.
