Specification of Letters Patent.

Patented Dec. 23., 1919.

i Application led July 30, 1918. Serial No. 247,419.

To all whom t may concern:

Ee it known that I, GEORGE F. WTELLS, a

n citizen of the United States, residing at Elyria, in the county of Lorain and State of Ohio, have invented certain new and useful Improvements in Eubber Heels for Shoes,` of which the following is a specification.

This invention relates to shoe heels and more particularly to rubber heels.

The primary object of this invention resides in the provision of a heel for shoes consisting of an embodiment of elements for prolonging the wear of the heel and preventing the slipping of individuals on wet or oily pavements.

'With these and other objects in view this invention resides in certain novel features of construction and arrangement of element hereinafter more particularly set forth and pointed out in the appended claim, it being understood that the right is reserved to resort to any change in construction as comes within the scope of the claim.

ln the accompanying drawing Figure l is a bottom plan view of a rubber heel as constructed in accordance with this invention;

Fig. 2 is a longitudinal sectional view thereof on line 2- 2 of Fig. l;

F ig. is a cross sectional view thereof on line 3 3 of Fig. 1.

ln the present embodiment of this invention. the letter l-l designates a rubber heel for shoes, boots or the like, which is provided with a concave inner surface B to create a suction on the bottom of the shoe and a similarly formed surface C of greater depth connnunicating therewith for cushioning the weight of an individual having these heels on his shoes.

Embedded as by dove-tailing in the lower portion of the rubber heel is a felt plug 6 the lower surface of which is disposed in a plane substantially in alinement with that upon which the lower edge of the heel lies.

This felt plug is provided along its edges with inwardly directed recesses which have their innermost walls 8 of areual formation and itsside walls 9 extended obliquely `inward to form doveetail pockets for the re cept-ion of rubber tongues 10 of a similar shape. Formed in the central portion of this felt plug is an aperture lil for the reception of a rubber lug 12 formed integral with the body portion of the rubber heel.

ln order to permit the felt plug to wear evenly, the bottom surface of the heel is concaved as at 13 with its edge disposed inV alinement with the lower surface of the felt plug.

llVith a felt plug having dove-tailed recesses along its edges, the tendency of the felt to separate from the rubber' is avoided as it is impossible for the dove-tail tongues of the rubber to pull out of the dove-tailed recesses in the edge of felt plug during the frictional engagement of the lower surface of the felt plugwith the ground.

Embedded in the rubber 'portion of the heel is a plurality of metallic washers let through which openings 15 in the rubber heel is driven the usual securing nails not shown.

With this invention fully set forth it is manifest that a rubber heel is produced which will prevent the slipping of an individual having the same secured to his shoes and through the wearing qualities of the material involved the expense of repairs will be reduced to a minimum.

Having thus described this invention what l claim is:

A cushion heel for shoes comprising an elastic body having a concave inner surface, whereby to create a suction on the bottom of the shoe and a similar formed surface of a greater depth communicating therewith, a felt plug dove-tailed into the lower portion of said heel the lower surface of which is disposed in a plane substantially in alinement with the lower edge of said heel, said felt plug being provided along its edges with inwardly directed recesses which have theirI innerl walls .of arcual formation the side walls extending obliquely inward to form dove-tail pockets, tongues forming part of the heel held in said pockets, the bottom surface of said heel being concaved with its edge disposed in alinement with the lower surface of said plug which has an aperture formed in its central portion, a lug formed integral with the body portion of said heel held in said aperture, and a plurality of washers embedded in said heel with openings communicating with the openings in said heel, whereby nails may be driven through said openings to hold said heel to its shoe.

In testimony whereof I aiiix my signature.

GEORGE F. WELLS.
