HEEL OF BOOTS AND SHOES.

Specification of Letters Patent.

Patented Sept. 6, 1921.

Application filed December 17, 1920. Serial No. 431,515.

To all whom it may concern."

Be it known that I, WILLIAM DAVID STERNBERG, a citizen of-the United States of America, and residing at 19 City road, London, E. O. 1., England, have invented certain new and useful Improvements in and Relating to the Heels of Boots and Shoes, of which the following is a specification.

This invention relatesto protectors or wearing part attachments for boots and shoes.

-The object of the invention is to provide a readily attachable and detachable part for the heels of boots or shoes, particularly in those positions where they are usually subjected to most wear.

According to the invention a carrier is provided in the manufacture of the boot or shoe or is subsequently fixed thereto, and is adapted to receive a wearing piece, and means are provided upon the carrier and (or) upon the wearing piece for temporarily securing the wearing piece in position.- These means may comprise the keying of the two parts presently to be described, or screwthreaded means, studs,

catches or other fasteners.

' For each carrier a series or set of wearing pieces'may be provided so that a new piece maybe readily fitted to 'a-carrier when the old one is worn.

It is preferred that the wearing piece should be keyed to the carrier by providing both the piece and the carrier with cooperative edges, for example, the edge, either the whole or a part, of the carrier maybe undercut and the wearing piece beveled to correspond, or the two may be rabbeted or otherwise interlocked.

The carrier and wearing piece may be made of rubber or any suitable material.

Further features of the invention will be hereinafter described and definedin the I 1 claims. 45

Fig. 2 is a plan of the wearing piece shown in Fig. 1.

Fig. 3 is an underneath plan view of a. heel from which the wearing piece has been removed and showing only the carrier. I Fig. 4 is a section on the line A. B of Fig.1.

Fig. 5 is an underneath plan view of a modified form of carrier and wearing piece applied say to the left heel of a boot.

F ig- 6 is an underneath plan view of a heel with carrier and wearing piece, illustrating a modification of the invention.

Fig. 7 is an elevation of the device shown in Fig. 6. I

Fig. 8 is a view similar to Fig. 6 showing an alternative form of securing means.

Fig. 9 is a section on the line CD of Fig. I In carrying the invention into effect according to one convenient mode by way of example, a carrier 1 in the form of a solid D-shaped block of rubber, or any other suitable material is provided. This D-shaped block or carrier 1 is of the same general shape as the heel but of smaller size, so that when the carrier is centrally placed in position a gallery is formed around it. The edges of this carrier are undercut or beveled as shown at 2(Fig. 1)101' a purpose which will hereinafter appear. This carrier is adapted to be secured by any convenient means to a heel 3, for example the carrier may be nailed or screwed thereto and when secured is intended to remain more or less permanentlyin position.

Around the carrier :1. wearing piece 4 of D shape (see, for example, Fig. 2) is adapteled surface 2 upon the carrier, so that the wearing piece when applied is keyed to the latter. The wearing piece may be formed of tough rubber.

The wearing piece 4 may be readily applied or sprung into position upon the heel upon which the carrier 1 is fixed by slipping the curved portion 6 under the correspond ing undercut portion of the carrier, pressing down the lateral portions of the wearing piece and rolling or twisting the straight part 7 snugly intoposition.

It is preferred that the inner perimeter of the wearing piece 4 should be slightly smaller than the exterior perimeter of the carrier 1, so that when the wearing piece is applied to the carrier upon the heel, the elasticity of the rubber causes it to contract upon the carrier and by reason of the beveled edges the wearing piece is drawn closely to and bedded vides the latter with portions or tract similarly'as the wearer walks and thus keep their meeting faces in contact thereby preventing dirt or grit from passing between them and getting behind the wearing piece and causing it to come off or become loose or have deleterious effects.

As a modification the carrier and wearing piece may be formed as shown in Fig. 5, that is to say, the rear portion of the carrier 1 may be of angular shape instead of rounded, and the wearing piece is formed of corresponding shape, both the carrienand the wearing piece being provided with the un dercut or beveled'edge as already described. This form of carrier and wearing piece prosurfaces 8 and 9 of increased width.

It is usually found that the outer side of the rear part of a heel, that is to say, the

. portion 8 in Fig. 5 as this represents a left takeplace.

heel, is subjected to the most wear and consequently becomes worn down while the reniainder'ofthe heel is comparatively little worn.

By the provision of the pieces 8 and 9'it will be seen that when the portion 8 in this case becomes'wor'n down, the-wearing piece may be removed from the left heel and trans ferred to the right. heel on which it will occupy a position on the "inner side of the boot while the-unworn piece 9 will take up the outer position in which most wear will By this transfer method the wearing piece may be worn down substantially uniformly, consequently increasing the life of thepiece to a considerable extent.

In Figs. 6 to 9 modifications areillustrated which are more particularly intended for use when the wearing piece is of such material that would be found inconvenient or impracticable to position it in the manner described abovejin connection with a rubber or resilient piece.

According to this form the D-shaped wearing piece 43* is divided, the juncture of the two parts being rabbeted as at 10, mortised and tenoned or formed with inclined faces as shown by the dotted line 11. An orifice '12 is provided in both ends of the piece'for the reception of a securing machine screw 13.

' The carrier is mounted on a plate 14: shown in dotted lines in Fig. 6. This plate is formed with an extension 15 which posse'sses a screwthreaded hole 16 for the reception of the machine screw 13. In order to accommodate the extension 15 in the plate'14i, the material of the wearing'piece 4 is recessed" or cut away. By the provision of a machine screw adapted to enter the tapped hole in the plate the wearing piece may be readily released. For convenie ce e l may be arranged vertically as shown in Fig. 7

8 and the extension 15 is bent upwardly at right angles to its plate 14 and located in a V reccss16 in the edge of the carrier 1. V

The base plate of the carrier is formed with holes ororifices which are disposed ap propriately to the position in which the nails or securing means are required, and the surface of the carrier may be marked to'indicate the position of the holes for convenience in driving in the securing nails.

. In order to insure a perfect bedding of any of the wearing pieces described upon the heel, the under surface may beinclined or beveled slightly from the outer peripheraledge toward the carrier. This beveled surface maybe flat or slightly curved inwardly as desired and causes a very close joint to be formed when weight is'put upon the heel,

at the meeting of the edge of the-wearing piece and the heel.

The carrier has been above described as an attachment'for a heel after the boot or shoe has been manufactured; the carrier, however, may be formed during manufacture as an integral part of the heel and the boot or -sh0edespatchedfr0m the factory with an appropriate wearing piece of any of the forms above described attached in position,- together with a series or set of spare wearing pieces for application in place of the original one supplied when the latter is Worn. According to this form the carrier may be nailed, sewn or otherwise secured in position as an integral part of theremainder of the heel.

Having now described my invention, what I claim as new and desire to secure by Let'- ters Patent is z-' r 1 1. A two-part resilient heel for boots and shoes comprising a carrier membena'nd an outer wearing member having a line of juncture extending to the'trea'd-surface, an integral projection or projections'on one of the members and a cooperating part or parts on the other serving to hold the members in position when the carrier is attached to the shoe, both members having substantially the same resiliency, the wearing member being s'ufiiciently elastic when stretched to pass over the carrier and force the projection-or projections into closely'locked relation with the cooperating part or parts wherebyf dirt and grit cannot enter between the two mem- V bers when the boot'or shoe is in use.

2. A wearing part attachment; for boots and shoes comprising a carrier of elastic ma terial, a wearing piece of substantially the same elasticity as the carrier and corresponding in shape to and embracing the carrier, with a line of juncture extending to the tread surface, said carrier having undercut edges and the wearing piece being provided with the corresponding internal bevel to snugly fit thereon whereby the wearing piece may be slipped on the carrier and said parts in expanding and contracting equally when in use will prevent the entrance of dirt and grit between the parts.

3. A wearing part attachment for boots and shoes comprisin a carrier of elastic rubber, a wearin piece of elastic rubber corresponding in s ape to and embracing the carrier, with a line of juncture extending to 15 piece may be expanded sufiiciently to be 20 pulled over the carrier and when in place said part in expanding and contracting equally when in use will prevent the entrance of dirt or grit between the parts.

In testimony whereof I have signed my 25 name to this Specification.

WILLIAM D. STERNBERG.
