3 Claims. (01. 36-35) My invention relates to rubber wearing pieces in the form of a portion of a heel, a call: or cleat which may be attached to a heel or the sole of a shoe, together with the means for preventing rotation of the wearing pieces and means to attach these to the heel or to the sole of a shoe.

An object and feature of my invention is the construction of a wearing piece formed of rubber. This has a recess formed in its lower surface in which a pronged metal washer may be inserted, the prongs of the washer extending upwardly through the base portion of the wearing piece and fitting into holes or sockets in the heel or the sole of the shoe.

A further object and feature of my invention is utilizing a single screw which extends through the center of the washer and through the base portion of the wearing piece into the heel or sole and thus forms the sole means for attaching the wearing piece to the heel or to the sole. The pronged washer has the function of preventing turning or rotation of the wearing piece relative to the screw.

Another object and feature of my invention is forming the heel or the sole of the shoe with a recess or socket to receive the base portion of the wearing piece, this therefore centering such wearing piece and giving a firmer mounting for suchwearing piece, either on the heel or on the sole of the shoe.

Another detail feature of my invention relates to forming the wearing piece with a central circular recess extending upwardly from its lower surface and with radiating'grooves, preferably three in number, extending outwardly from the center of this recess or socket; these grooves being preferably equally spaced apart. The base portion of the rubber wearing piece preferably has a deep recess or socket or a perforation in alignment with the larger socket from which the grooves radiate, this deep recess or perforation being to accommodatethe screw which attaches the wearing piece to the shoe, heel or sole.

Another detailed feature of my invention is forming the washer with a circular central or hub portion preferably counter-sunk, from which extend three radial arms to fit in grooves above mentioned. -This washer has upturned ends or prongs which pass through perforations in the base portion of the wearing piece and extend into sockets or the like in the heel or sole.

Another object and feature of my invention especially adaptable for high heeled women's -shoes, is forming the wearing piece with an upward cylindrical projection or boss which fits into a circular recess in the lower face of the heel, such heel being usually made of wood. In one form of my invention the screw extends through the center of this boss, being threaded upwardly into the heel. In another 5 form of my invention I secure the wearing piece by a collar pin or the like, which passes horizontally through the heel and engages this up wardly extending boss. The head of the collar pin is preferably at the rear of the heel and the i0 prongs of the collar pin are bent laterally at the front face of the heel.

My invention is illustrated in connection with the accompanying drawing, in which,

The rubber wearing piece is constructed as follows, having reference particularly to Figs. 4, 5, 6, 9 and 10. This wearing piece may be designated generally by the numeral II and has. a bottom surface I? and a top portion It. A 45 central circular socket or recess It extends upwardly from the bottom surface terminating at a surface l5 and the portion between this surface l5 and the top It may be considered the base portion I 6 of the wearing piece. Where the wearing piece is used on a heel, thisis provided with a straight front edge 'll, opposite side edges I8 and a convex curved rearedge l9. Also where the device is used on the heel there is preferably a cylindrical boss 20 extending upwardly 5 face l2. Also in the from the upper surface It and terminating at 2|. The surface 2| is parallel to the bottom surwearing piece for a heel construction there are a plurality of radiating grooves 22, these extending from the axial center of the socket or recess ll. Extending upwardly from the base of the socket I there is preferably a tapered perforation 23 to accommodate a screw as hereinunder detailed and at the end of each of the grooves 22 there is a perforation 24 to accommodate a pronged washer described hereinunder.

This pronged washer is designated generally by the numeral 25 (note Figs. '1 and 8) and has a central circular hub section 26 countersunk upwardly as indicated. at .21. From this hub there are three radiating arms 28 to be used in cases where there are three grooves'22 and at the end of each arm there is an upwardly extending prong 29 parallel to the axisof the washer. 7

Where this construction of wearing piece is used on a heel such a heel designated by the assembly numeral 30 has the usual fiat front face 3|. The side faces 32 for a short distance are vsubstantially parallel and are connected by the convex curved rear side 33. Thus the contour of the lower surface 34 of the is usually made of wood, conforms to the shape of the wearing piece to be attached thereto. The heel is provided with a cylindrical recess or socket 35 having an upper base surface or shoulder 36.

' washer.

In the attachment of the wearing piece to the heel this is correctly aligned with the heel. There are also shallow sockets 31 equally spaced around the recess 35 to accommodate the prongs of the pronged washer. This washer isfitted in the socket or recess I l and in the grooves 22 in the rubber wearing piece. 'The prongs are forced upwardly through the perforationsil and the countersunk portion 21 of the hub 26 fits into the upper end of the perforation 23'. A wood screw is then threaded upwardly through the The shank or stem 28 of the screw passes through the perforation 23 and thus through the base portion 1-8 and the cylindrical boss 20 and being threaded into the heel; The screw is preferably formed with a bevelled head 40 fiat on its exposed end. The counter-sink 21 is made to conform to the bevel or cone shape a of the head of the screw and of such a size that when the screw is properly threaded in place the end face 40 of the screw extends .-upwardly above the hub portion 28 of the washer and-thus above the arms 28.

It will thus be seen that the screw firmly at- .taches the wearing piece to the heel. This attachment is aided by the boss 20 fitting in the recess-35 and the prongs of the washer prevent rotation of this wearingv piece on the screw.

, In Figs. 9 and 10 Ishow an adaptation of my invention to the attachment of wearing pieces j on; its peripheral sole is indicated by or cleats to ashoe sole. In this instance the the numeral 40' having a circular socket L; .The cleat is cylindrical edge qto seat on the bottomof the socket ll. Thecleat is-provided with a recess from itslower surface,.this recess being pref- 70 4B extendingupwardly erably cylindrical, thus leaving an annular rim 4t. a pronsed washer similar to; that shown in ligs-..'l and-8 but ofv treproper size, is utilized.

in the upper or base portion heel proper which shoulder at right angles to the 42 and has a fiat base M,

of the cleat or wearing sharpened at their end so that they may be forced into the shoe sole or the shoe sole may have piece. These be It is obvious that with the construction of Figs.

9 and 10, the wearing piece may be attached to the lower surface of the shoe sole instead of having a'socket to accommodate the wearing piece or cleat.- In such case it is desirable to form the pronged washer with somewhat longer prongs than that shown in Fig. 10.

Various changes may be made in the details of construction without departing from the spirit or scope of the invention as defined by the appended claims.

I claim:

1. The combination of a shoe heel having a plane lower surface with a cylindrical socket extending upwardly, a resilient wearing element having a cylindrical boss to fit in the socket, a shoulder to bear on the plane surface of the heel, the wearing element having a circular recess, a washer in said recess, and a screw extending through the washer and the center boss into the heel, the wearing element having grooves radiating from the central recess, the washer having radiating arms extending along said grooves, the washer having upwardly turned prongs, the said prongs passing through the shoulder portion of the wearing element and. en-' socket.
