SHOE-HEEL.

Specification of Letters Patent.

Patented Apr. a, rare.

Application filed .Tune 13; 1918. Serial No. 239,793.

f all "whom, it may concern:

Be it known that I, FRANK VVHAR'roN,

' a citizen of the United States, residing at Elyria, in the county of Lorain and State of Ohio, have invented new and useful Improvements in Shoe-Heels, of which the following is a specification.

This invention relates to detachable heels for shoes and is especially designed for application to ladies shoes, or shoes having the high or well known French heel. Heels of this type are usually made of wood, with a plate of aluminum or other metal secured thereto th elatter being covered with a thin fifi er of leather or similar. material.

This plate and covering quickly become worn, or, owing to the rigidity of the heel, the latter frequently becomes detached from "the shoe through the shock or jar occasioned in ordinary walking.

To overcome these and many other disadvantages, the invention includes a metallic plate adapted to be secured to the wooden or other heel and having projecting from its face, studs, preferably three in number. These studs are adapted for entrance into openings formed in the compressible lift, which has embedded therein a plate having apertures which register with the openings in the compressible lift and a central aperture which registers with a central opening in said lift for the reception of a screw or other fastening device.

The invention further includes the fob lowing novel details of construction, combination and arrangement of parts, to be hereinafter more fully described and illustrated in the accompanying drawings.

In the drawings:

Figure 1 is a side elevation of a shoe heel with the compressible lift attached thereto;

Fig. 2 is a central vertical sectional view of the same;

Fig. 3 is a section showing the manner of engagement between the lift and plate;

Fig. 4 is a detail perspective view of the plate;

Fig. 5 is a similar view of the compressible lift; and

Fig. 6 is a like view of the spring plate which is en'ibedded or molded in the lift.

Referring to the drawings in detail. like characters of reference denote corresponding parts, throughout the several views.

The shoe heel as illustrated in the accompanying drawings, is formed of wood or.

other suitable material and is shown as of the French heel type, being indicated at 10.

A metallic plate 11, preferably formed of aluminum is provided, thesaid plate being formed with openings 12 for the passage of nails or similar fastening devices, by means of which the plate is secured to the heel. This plate has projecting laterally from the under face thereof studs 14, these studs being preferably three in number and integrally formed with the plate.

Adapted to fit the under face of the plate 11 is a compressible lift 15, preferably formed of rubber. This lift is provided with openings 16 extending entirely there through. It is also provided with a spring plate 17, molded or otherwise embedded in the lift, the plate 17 being of substantially triangular shape and having apertures 18 therein, which register with the openings 16. The plate 17 is embedded in the lift adjacent the upper face thereof and the studs 14 are adapted to be inserted in the openings 16, the said studs being of sufficient length to enter the apertures 18 of the plate 17. This securely holds the lift 15 against lateral movement with respect to the plate. In order to provide a seat for the plate, the lift 15 has its upper surface formed with a depression, which is surrounded by inclined walls 19, which are adapted to engage the beveled edges 20 provided around the edge of the plate 11.

Formed in the lift 15 is an opening '21, which also extends entirely therethrough, while the spring plate is provided with a central opening 23, which is adapted to register with an opening 24 in the plate 11. A. screw or other fastening device 25 is adapted to be. inserted through the openings 21, 23 and 24 and to engage the heel '10 for the purpose of securely holding the lift in position. The head of the screw 25 will force the compressible material by which the lift 15 is formed away from the opening 23 in the plate 17, so that a shoulder is formed at this point for engagement with the said head. hen securely adjusted in position, the screw 25 will flex the plate 17 so as to hold the upper face of the lift 15 tightly against the adjacent face of the plate 11.

By forming the openings 16 entirely through the lift 15, the plate 11 may be dispensed with when desired and the lift secured by means of nails or other similar elements, the heads of the nails forcing the.

material forming the lift away from they openings 16, so that a shoulder for engagement with the heads is provided around the openings 18, after the manner of the shoulder described in connection with the screw 25.

In moldingthe lifts, they are preferably formed in the manner shown, so that their upper edge is of substantially the same size and shape as the plate 11, so that it is only necessary to smooth down a small portion of the upper surface of this edge to obtain a perfect fit.

The invention is susceptible of various changes in its form, proportions and minor details of constructionand the right is reserved to make such changes.

Having described the invention, what is claimed is In a shoe heel, a plate, means whereby said plate maybe detachably secured to the heel portion of a shoe, a compressible member,

aspring late embedded in said compressible mem er, said spring plate being provided with outwardly extending ofi'set portions, which incline toward the heel portion of the shoe when the compressible member is in position, a headed securing element passing through an opening in and contacting with the under surface of the spring plate
