RUBBER HEEL.

Application filed April-19, 1923. Serial No. 633,059.

This invention relates to rubber heels and more particularly relates to rubber heels comprising a relatively permanent part and a replaceable part arranged to receive the 5 main wear.

,It is the object of the invention to provide a rubber heel having a. main body portion adapted for permanent attachment to a shoe, and formed of relatively hard rubber, and

a replaceable portion of comparatively soft rubber forming that portion of the heel which is mainly subjected to wear, said replaceable portion being cemented or otherwise detachably secured in place.

The invention consists in the structural features hereinafter described and illustrated in the accompanying drawing, wherein,

Fig. 1 is a perspective view of the heel portion of a. shoe, equipped with the improved rubber heel, the replaceable element of said heel being shown detached.

Fig. 2 is a bottom view of the rubber heel with the replaceable element in its position of use.

Fig. 3 is a cross section on line 33 of Fig. 2.

In these views the reference character 1 designates a shoe, and 2 is the main body member of a rubber heel secured to said shoe b nails 3 and 4, said member bein forme of relatively hard rubber. Sai

heel further comprises a replaceable element '5, formed of comparatively soft rubber, the extent and location of which element is such as to subject it to the major portion of the wear to which the heel is subjected. Thus said element extends from the forward end of the heel along the outer side portion of the same and has its rear part curved to cover the rear central portion of the heel. The thickness of the replaceable element is approximately half that of the main body member, the latter having however, a recessed portion 2 of reduced thickness conforming to the shape of the replaceable element and forming a seat for said element.

The nails 3 which secure the thicker portion said member are preferably provided with elongated heads 6 which project slightly above the face of said member and are adapted to register with and engage in blind sockets 7 formed in the under (or seat-engagin face of the replaceable member 5, thus t e nails 4 serve as dowel pins to assist in properly ositioning said member and for increasing t e retention of the latter without penetrtaing or marring the wearing surface thereof.

The described rubber heel is adapted to more effectively absorb shocks than the ordinary one-piece construction, since it provides a relatively freely yielding portion taking care of the initial shocks arising from contact with the side walks or floor and provides the less yielding body ortion which takes the weight as the heel a justs itself to i the engaged surface. Also the described heel is more economical than a one-piece structure inasmuch as only the worn portion need be discarded and replaced.

What I claim is:

The combination with a shoe, of a rubber heel having a portion of reduced thickness extending to one margin thereof, and providing a seating surface, elements securing said reduced portion to the shoe having heads bearing on said seating surface, and a replaceable tread element seating upon said seating surface and formed with blind sockets in its seating face engaging the heads of said securing elements to hold said replaceable tread element properly positioned.

In testimony whereof I sign this specification.
