, inglilemen-tsfor Shoes, of vwhich theffollowing is a specification.

This invention relates to shoe heels or soles and has for its lprimary object the provision of meanswhereby slipping of the foot will be prevented.

a rubber heel or sole will be provided with wear-resisting qualitieswithout losing any of its resiliency, and a further obJect of the invention is to provide a wear-resisting and non-slipping element which may be iirmly embedded in a rubber shoe heel or sole and which will readilyyield o r move with the sole Or heel without becoming loosened therein. The invention is illustrated in the accompanying drawings and will be hereinafter fully set forth anddefined.

In the drawings- Figure 1 is a perspective view showing a rubber shoe heel provided with my improvements; f

In the accompanying drawings, I- have shown the device applied to a heel l consisting of rubber throughout, but it will be understood that the invention may be ap-V plied to a rubber heel lift which is to be attached to a shoe heel of leather or other material. It willalso be understood that the sole 2 may -be entirely of rubber or rubber composition or may be constructed in lifts or layers, the outer layers or lifts being of a resilient material, while the upper or inner lifts o-r layers may be of leather or other relatively hard material. In carrying 'out my invention, I incorporate in the heel or the sole a wear-resisting stud or element consisting of 'a body V3 of circular outline having a at ylower face 4 provided 'centrally with a socket 5. vThe lower edge of the lbody may be slightly beveled, as

' shown at 6, so as to impart a neat appearance to the stud and also accommodate the angle at which the heel impinges upon the Another object of 'the invention is to provide means whereby isi-"ica,

ground .in the act of walkingf Rising cen-` trally from the upper'end'of the body 3 is a shank or stem 7' whiclrcarries at its upper end a conical head 8, as shown. "The upper end of the body 3 is dished orA concave, as

shown Vat 9, yand the under-i surface of the conical head 8 is shown at l0. The studs are,

'of course, formed'l sepaalso dishedor concave, as

rately fromand prior to theirplacement in i the heel and, in the manufacture of the heel, the studs are placed in position within a mold and held against displacement therein by having the socket 5 engaged'overa pinor stud on the bottoni of the mold. The rubber or other composition from which the heel or sole listo be formed is .then i poured into-.the mold in the'usual manner and permitted to set. The rubber or other material, being in a plastic state, will flow around the stud so as to completely embed the same and fillthe entiresp-ace between *the upper sideI of the body of the stud and the lower side ofthe heady. The concave formation ofthe opposed surfaces of -the body and the headfwill permit the rubber or other material to firmly embed theV stud sothat it `cannot be withdrawn.V 'At-the same time this. formation of the device WillA cause the material of the heel or sole to, in

effect, form la diaphragm snugly embracing theshank or stem 7 and conforming to the opposed concave surfaces of the body and the head so that relative lateral'movement of the Ystud within the heel or sole will be prevented.k At the same time iinpact of the stud against a pavement Or the y The heel or lsole may be attached to the shoe in any preferred manner, as by nails, l

pegs-or by sewing, and the studs maybe provided in any desired number. accompanying drawings, I have shown two In the studs applied to the heel at'therear edge of the saine so that they are located at the points ordinarily receiving the greatest wear. It will be understood, however, that lll) the studs maybe provided around the er1- tire edge of the heel'or the sole or arranged to cover the entire tread surface of the saine.

My device is exceedingly simple and may be produced and applied to a heel without any appreciable increase in the cost of the heel or sole. The resilient qualities of the heel or the sole are not lessened in any degree b-y the use of my wear-resisting and anti-slipping device while the life of the heel or the sole is'prolonged. Upon impact with the ground, the stud tends to move relatively upward within the heel or sole and this action is aided by the diaphragmlike support for the stud provided between the body andthe head of the same which follows the movement of the stud and mainftains; constantly the relation `between the stud and the rubber so that, after the initial impact with the ground, thestud may readily move relatively in a downward direction so as to retain its engagement With y the ground andV this action will be accelerated and facilitated by the elasticity or resiliency ofthe said diaphragm f portion of the heel.

Having thus described. the invention, what is claimed as new is:

l. A wear-resisting element to be embeddedin a cushion heel or sole compris-V ing ya body having a concave upper side, a

comparatively narrow stem extending up-` wardly axially from the body, and a head carried by the upper end oirV the stem and having a concave under side presented toward the concave upper side of the said body whereby a firm holdl isv obtained in Ylateral direction by said con-cave sides.

comparatirely narrow stein extending iipwardiy axially 'from the body, and a head carried by the upper end oit the stein and having a concave under side presented toward the concave upper side of the said body whereby a lirm hold is obtained in lateral dirextion by said concave sides, the body and head being of circularv contour and the head being or a diameter less than that of the body.
