RESILIENT r-rnnt.

Specification of Letters Patent.

Patented Dee. 23,10t9;

Application filed May 31, 19th. Serial No. $337,434

To all whom it may concern:

Be it known that T, LAWRENCE T. FAY, a a citizen of the United States, residin at llfllyria, in the county of Lorain and tate of Ohio, have invented a. certain new and useful lmprovement in Resilient Heels, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

This invention relates to resilient heels, and one of the objects is to construct a resilient heel in such a manner as to increase its resiliency without sacrificing itswearing qualities. A feature of the invention is that resilient heels constructed according to this invention may be made of more unyielding rubber or like material than that ordinarily used and still be more resilient and yielding than softer rubber. Another object is to so arrange the heel that it may be very capable of easy application and adapted to resist anytendency to slip.

iii tl Elli titl

My invention is hereii-iafter more fully described in connection with the accompanying drawings. Othere objects will become apparent in such description and the essential characteristics are summarized in the claims.

in the drawings, ll igure 1 is a-vertical longitudinal section through mv heel affixed in osition; lFig. 2 is a bottom plan of the bee Fig. 3 is a top plan of the resilient heel removed; Fig. 4c is a transverse sec- 'tion taken substantially on the line H of Fig. 2; Fig. 5 is a bottom plan of a securing plate for the rubber heel.

Describing the parts by the use of reference characters, A and B indicate the-counter and sole in broken lines; C indicates the solid portion of the heel usually construct-- ed of leather and having a flat bottom surface, to which my rubber heel may be atfixed. As shown my rubber heel is as the same exterior contour as the solid portion and comprises a body of rubber formed to present a wide rib 11 surrounding a re cess 12, the sidesof which are substantially in conformity with the rim of the heel.

its shown, this rib is undercut so that its edges are'beveled at 13, sloping upwardly to a substantially flat surface 14, the area of the upper surface 14: of the recess being greater than the opening of the recess.

Between the surface 14% andthe upper surface of the rubber heel, T have shown a plate 16 of metal or similar still material embedded in the rubber, and projecting upwardly from this plate are suitable securing members, such as pegs or nails 17 and 1 8. The peg 17 is shown as the central peg which I prefer to make longer and larger than the others for convenience in centering the rubber heel and positioning the same before driving the securing pegs 18 in the solid portion. These pegs are preferably of the same material as the plate and are rigidly secured thereto as by soldering so that the rubber heels when a.

completed are equipped with projections extending upwardly from the rubber and adapted to-be driven into position by striking the rubber preferably over the heads of the pegs, although striking the rubber at any portion of the bottom of the surface 145 of the recess, transmits its force through the plate to the pegs and facilitates the driving thereof.

To still further add to the resiliency of the tread portion of the heel, in other words to render the raised broad ribs 17 very yielding in proportion to the stiffness of the material, T provide cavities 20, shown as opening upwardly and closed by the lower surface tr the solid portion of the heel whereby air is imprisoned in these cavities when the heel is in position, forming a pneumatic cushion resisting the compression of the ribs 11 as the wearer puts his weightthereon. By this means, the resiliency of the heel is increased and l am able to use more rigid and tenacious material. Because of such added resiliency and enabling the use of wear resisting material, the life of the heels is greatly extended, it being a welllrnown fact that up to certain limits, the resiliency of the heel adds to the wearing qualities. The formation of the cavity particularly with the downwardly and inwardly slopin walls, also adds to the'compressibility o the tread portion which has the following desirable effect, namely, that as the wearer stepson the heel, the entire tread portion is compressed and air is forced from the cavity 13, causing vacuum in the n cavity which tends to prevent slipping and which does not interfere with the raising of silient material interchangeably in the foregoing specification for the reason that my heel may be constructed of any resilient material and a change of such material does not constitute a departure from the spirit of his invention.

Having thus described my invention, what- I claim is:

1. A resilient heel having asubstantiallv flat upper surface adapted to fit the solid portion of the heel, securing means embedded in the rubber and having projections-extending upwardly therefrom, a substantially flat tread surface and a cavity within the tread surface, the sides of the cavity sloping upwardly and outwardly from thetreading surface '2. A' resilient heel, consisting of a body portion, a raised rib having a substantially flat broad surface extending entirely around the perimeter of the heel and air eavitiesformed in said rib opening upwardly and closable by the lower surface of the solid heel portion of the shoe and a plate embedded in said body portion, being .rib portion covered both above and below by the material of the resilient heel and havin its edges extending past the inside edge of the to a point adjacent the cavity.

3. A resilient heel having a substantially flat tread surface extending around the perimeter of the heel and a cavity within said tread surface, the sides of the cavity sloping upwardly and outwardly toward the sides of the heel, a securing plate embedded in the rubber of the heel. being covered above and below by the rubber and extending outwardly past the upper larger portion of the -avity, and a series of upwardly opening cavities formed between the edge of said plate and an outside perimeter of the heel and closed by the lower surface of the solid portion of the heel of the shoe.

4'. The combination, with a solid heel section. of a resilient heel section comprising a body, and a downwardly extending rib having a comparatively broad flat surface extending entirely around the perimeter of the heel. and having cavities formed in the material above the rib and approximately centrally spaced with relation to the inner and outer walls of the rib, opening upwardly from the resilient section and closed by the solid section of the heel, such cavities forming a substantially continuous series extending around the heel and spaced apart sufliciently to provide an intermediate connecting bracing portion between them.

In testimony whereof, I hereunto afiix my signature.

LAWRENCE T. FAY.
