Application filed MRTOh'l/l, 1522. Serial No. 543,668.
T 0 all whom it may concern:
Be it known that I, FRANK REDMAN, a citizen of he United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Shoe Heels, of which the following is a specification.
This invention relates to cushion shoe heels and the main object is to provide a heel which has the combined qualities of a relatively long wear and a tread so designed as to insure the wearer from slipping on a wet or otherwise slippery pavement.
Another object is the provision of a cushion heel comprising a main body permanently secured to a shoe and a separate member, so located as to receive most of the wear, which can be rotated to a new position.
The above objects will become apparent in the description in which like characters of reference refer to the like-named parts in the drawing.
Referring briefly to the drawing, Figure 1 is a top plan view of the cushion heel.
Figure 2 is a sectional elevational view of the same taken on line 22 of Figure 1.
Figure 8 is aperspective view of the rotatable wearing disc and shows the tapered retaining wall formed thereon.
Figure 4 is a sectional elevational view similar to Figure 2 but with the tread-disc removed from the recess thereof.
Figure 5 is a fragmentary cross-sectional view of a portion of the disc showing the method of retaining a reinforcing plate in permanent position therein.
Describing the drawing more in detail, the numeral 10 designates the main body structure of a rubber cushion heel, having its surface 11 to contact with the shoe heel and is formed with a marginal raised edge which will snugly fit the heel.
A rubber cement is applied on the surface 11 when assembling on the heel of the shoe so as to keep it from sliding or chang ing its position.
This main body structure 10 has a series of spaced holes 12 to receive the usualnails or screws by which it is securely attached to the shoe.
The wear surface 13 is provided with a plurality of elevated bosses 1s around the holes 12 and are moulded integral withthe body 10.
The rear part of the body 10 has a rela tively deep annular orifice 15 having a straight wall 16 at its open end diverging at its center and coming to its greatest diameter at the lower end of the orifice, the
bevelled portion of the wall being indicated I I receives a screw, the latter being adapted to pass thru the body wall 24: and into the heel of a shoe. of the disc is of such height as to lie in a coincident level plane with the bases 14:.
Said disc 18 is provided with a circular stiffener plate 25, which has a series of holes 26, and is concentric within the body of the disc at the intersection of its straight and bevelled walls. The plate 25 is embedded in the disc while the latter is moulded and roughly divides the same into two portions which are joined to each other at the outer edge of the plate and also thru the holes 26.
After cementing, the heel is fitted to the shoe and the nails are driven thru holes 12 and into the shoe thereby securing the, main body structure rigidly to the shoe.
As the entire body is composed of tough but flexible rubber, it is comparatively simple matter to stretch the walls of the orifice 15 outwardly so that the lower tapered end of disc 18 can be inserted therein. Said disc is preferably moulded slightly smaller than the orifice so that the same may be readily rotated in the latter when pres sure is applied.
The advantages gained by providing a tread disc are that, after the heel has worn so that a new surface is required, a partial rotation of said disc will present a new and The raised portion 22 relatively unworn portion for wear, which is accomplished by applying rotational pressure upon the flanged head.
Another feature is that replacement or renewal of: the disc will practically give a new heel Without the necessity of removing and replacing the entire body structure.
It is also to be borne in mind that the raised portions ii on the body and 22- on the disc can he made into any design, each of which is provided with a hole to form a vacuum cup, which will. when in cont-act with the pavement, counteract the tendency of slipping, thus giving a firm and secure foothold.
l claim A shoe heel comprising a relatively hard rubber plate having a raised marginal border on its attaching side, a plurality of uniformly raised projections on the tread side and a circular recess having undercut walls formed in said plate on the tread side, said recess extending nearly through the plate, a softer rubber disc suited to he re ceived in the mentioned recess, said disc having a raised central portion containing a conical opening adapted to receive a spreading screw a metallic plate in said disc, said plate having a plurality of openings into which the material 01 said disc enters and an annular flange on the outer side of said disc overlying said plate, said nange resting upon said plate substantially in iegister with the raised projections.
