PATENT OFFICE.

JAMES G. ROBERTSON, OF NEW YORK, N. Y.

HEEL.

Specification of Letters Patent.

Patented Dec. 13, 1921.

Application filed May 20, 1918. Serial No. 235,487.

To all whom it may concern:

Be it known that I, JAMES G. ROBERTSON, residing at New York, in the county and State of New York, have invented certain new and useful Improvements in Heels, of which the following is a specification.

This invention relates to heels, and the prime object thereof is to provide a heel which will remain straight through use.

Another object of the invention is to provide a device designed to be used upon the heel of a boot or shoe, such that it will insure an even wearing of the heel during its frictional contact with the ground.

Another object of the invention is to provide a device of the above character designed to be used upon the heel of a boot or shoe, such that the appearance of the heel is not changed, the device being substantially invisible when the boot or shoe is being worn.

Other objects and aims of the invention, more or less specific than those referred to above, will be in part obvious and in part pointed out in the course of the following description of the elements, combinations, arrangements of parts and applications of principles, constituting the invention; and the scope of protection contemplated will be indicated in the appended claims.

In the accompanying drawing, wherein I have illustrated a preferred form of embodiment of my invention:

Figure l is a plan view, showing the bottom surface of the heel equipped with my improved device.

F i 2 is a sectional view taken on line II-II of Fig. 1; and

Figs. 3 and at are perspective views, showing the details of construction.

Referring now to the drawings, wherein similar reference characters refer to similar parts, the reference numeral 1 denotes the body portion of the heel to which my improved device is attached. 2 denotes a support which is interiorly of the heel, preferably near the center portion thereof, said support being pointed so that it may be driven through several of the layers of leather of which heels are commonly constructed. The support 2 is provided upon its upper end with a head 3, which is received in a centrally disposed socket 4. of a circular casing 5, said casing being provided with a disk-shaped bottom wall 6 and an upstanding rim 7. Portions 8 of the easing are struck downwardly and inwardly so as to engage the lower surface of the head 3 of the support 2, whereby said parts are fastenedtogether. While the casing is held in position upon the heel it has a rotative movement relative to the support.

The casing 5 is set into the bottom surface of the heel, as clearly shown in Fig. 2. Positioned within the casing and fixed therein, as by means of struck-up portions 9, which enter the material thereof, is a disk-shaped member 10, which is preferably formed of leather, rubber, or some suitable fibrous material possessed of anti-slipping. qualities. The disk, it will be noted, is confined within the casing 5 so that it can rotate therewith.

Located directly behind the disk, and fastened to the material of the heel proper, is a semi-circular strip of metal 11, preferably steel, said strip being held in position as by means of the nails or pegs l2; and located directly behind this metallic strip is a similarly formed strip of yieldable material 13, such for instance as rubber. This strip which forms the rear edge of the heel is fastened to the heel proper, as by means of the nails or pegs 14:.

Thus it will be seen that the bottom of the heel is provided with a centrally located revoluble disk 10, the metallic strip 11, and the strip 13 of softer material, the latter conforming to the rear contour of the heel.

Having thus described my invention, the operation thereof may now be understood. During the act of walking the contact of the heel with the ground will tend to rotate the disk 10 so that all portions thereof will be worn evenly, owing to the fact that the disk is rotated. If desired, the disk may also be manually rotated as by inserting a screw driver or coin in the slot 15, which can be conveniently done by the wearer.

The rearwardly located cushion member 13 relieves the shock due to the contact of the heel with the ground, and the metallic strip 11 takes the wear that would otherwise be sustained by the cushioning member 13.

As many changes could be made in this construction without departing from the scope of the following claims, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative only and not in a limiting sense.

Having thus described my invention what I claim as new and desire to secure by Let ters Patent is:

1. In a device of the class described, the combination with a heel having a recess formed in its lower surface, a casing rotatively mounted in said recess, means for rotatably supporting said casing, a disk inserted within said casing, and a metallic strip located behind said casing and forming a portion of the inclosure thereof.

2. In a device of the class described, the combination with a heel having a recess formed in its lower surface, a casing rotatively mounted in said recess, means for rotatably supporting said casing,'a disk inserted within said casing, a metallic strip located directly behind said casing, forming surface, a disk shaped member located within said recess and adapted to rotate therein, a metallic strip WlllOh conforms to the contour of said disk and forms a portion of the V inclosure, and a cushioning strip located behind said metallic strip. I

In testimony whereof I aflix my signature in the presence of two witnesses. V

JAMES G. ROBERTSON.
