FRANK sang, or DELAWARE, OHIO.-

' SHOE-HEEL.

Application filed September 2, 1919.. Serial No, 320,993.

To all whom it may concern:

Be it known that I, FRANK SAHR a citizen of the United States, residing at belaware, in the county of Delaware and State of Ohio, have invented certain new and useful Improvements in Shoe-Heels, of which the following is a specification. I

This invention relates broadly to shoes, and has particular reference to the heel construction thereof, the object of the invention being to provide a heel of the socalled French heel variety which may be securely connected with the shoe body, strong and durable in construction, easy to repair, and to render the connection between the same and the body of the shoe of such character as to eliminate undue breaking of theheel or lateral distortion of the same.

Tothis end, the invention comprehends, among other features, the provision of a shoe heel which is formed from metal, preferably aluminum, and which is suitably shaped to define a heel of any configuration,said heel being provided with a securing plate, which is attached to the under portion of the shoe body immediately above the heel proper and is provided with an extension protruding through an opening formed in the heel, said extension having its lower end provided with a threaded opening with which is engaged a suitable screw, the latter serving to clamp a wear plate to the under portion of the heel so that the latter will be retained in a secured manner upon the extension, said wear plate being formed with means whereby a leather wearing surface may be connected with the same.

For a further understanding of the invention, reference is to be had to the accompanying drawing, forming a part of this specification, and in which similar characters of reference denote like and corresponding parts:

Figure 1 is a vertical sectional view taken through a heel constructed in accordance with the principles of the invention.

Fig. 2 is a perspective view of the securing plate and its associated extension.

Fig. 3 is a perspective view of the heel member, and,

Fig. 4 is a similar View of the clamping plate.

Referring more particularly to the details of the invention, the latter in its preferred form consists of a heel structure 1 which is adapted to be attached to a shoe 2 of any desired formation. In order to construct the heel 1 so that the samewill retain its proper configuration and will be of a strong and substantial character, I preferably provide the rear under portion of the shoe body with a fixed metallic plate 3, this plate being shaped so as to follow the general plan curvature of that portion of the. shoe with which it engages. Suitable fastening elements 4 may be utilized for thepurpose of connecting the plate 3 with the shoe in a rigid manner. In order that the plate 3 will present a neat and pleasing appearance and to enable the same to readily coo erate with the sole 5 of the shoe, the forwar edge of said plate is preferably grooved as at 6, and this grooved portion isadapted to receive the end-of the sole 5. In th1s manner, the end of said sole 'may be securely connected with the-plate 3 and the construction of the shoe thereby rendered of a substantial nature, particularly as this applies to the heel portion.v

Formed withthe plate 3 is an extension 7. This extension includes a substantially circular base portion 8 and an: extended shaft portion 9, the extensionlying on a slight angle with respect to the plane of the plate 3, said angle conforming generally to the inclination of the heel proper. Adapted to be received by the securing plate and its extension 7 is a heel shaping member 10. This member is also formed preferably from metal, and if aluminum is used, the same will lighten the general weight of the heel. This member 10 ma be any one of many shapes but is prefera 1y fashioned after the so-called French heel. The upper surface of the member 10 is rovided with a depression. 11, which is ormedto receive and surround the securing platel3, so that the latter will be concealed from an exterior view. The depression 11 communicates with a socket 12, in which the base portion 8 of the extension 7 is adapted to be situ ated, and the socket 12, in turn, further terminates in a bore 13 in which the portion 9 of the extension 7 is adapted to project, the bore 13 being disposed on the same angle as the extension 7.

In order to clamp the member 10 to the shoe proper, use is made of a clamping plate Specification of Letters Patent. v Patented una22, 1920.

14. This plate is preferably formed from metal and is of substantially the same configuration as the lower endof the member- 10, and when viewed exteriorly the clamping plate forms a pleasing continuation of said heel member. To secure the plate-14 in position, the same is provided with a groove 15, in which a shoulder 16 formed on the lower surface of the member 10 is adapted to be situated. The presence of the shoulder 16 prevents undue slipping of said clamping plate upon the lower surface of the heel member. The clamping plate is further formed with an upwardly extending tubular projection 17 which is adapted to be received within the bore 13 and receives the shaft portion 9 of the extension 7, as is clearly shown in Fig. 1. To retain the clamping plate in this position and to there-- by securely connect the heel member 10 with the shoe 2, said clamping plate is formed with an opening 18 which alines with a similarly situated opening 19 formed in the lower end of the extension 7. A screw or its equivalent 20 is arranged to pass through the opening 18 and is threaded into the opening 19 so that the clamping plate may be drawn toward the permanent plate 3 and in this 'manner will clamp the heel member 10 between said plates in a positive and substantial fashion. The under surface of 'the clamping plate 14: is provided with a socket 21, in which a leather insert 22 is positioned, said insert serving to receive the head of the screw 20 and in this manner is retained within the socket 21. A layer 27 of leather is arranged upon the under surface of the plate 14 and is secured to the latter by passing fastening elements 28 therethrough and into the insert 26. Obviously, by use of the layer 27 the heel is cushioned and its operation is therefore rendered substantially the same as a heel ofordinary construction, also, the layer 27 may be formed from rubber or a composition thereof if desired.

In view of the foregoing description, taken in connection with the accompanying drawlngs, it will be apparent that there is provided a heel of exceptional strength and stability, and one which may be worn with comfort and assurance. By forming the heel 1n the manner stated, the possibility of the same becoming broken is reduced to a minimum and by eliminating this objection,-

the present invention is believed to overcome the serious defect existing in many of the heel structures of common usage. Also, the structure 1 is firmly braced against lateral strains and hence twisting or lateral distortion of the heel is prevented. When the layer 27 becomes worn, the same may be readily removed and repaired in the ordinary manner.

The securing plate 3 may be provided with a centrally disposed depression 29, this depression serves in a measure to provide an air cushion in the heel and hence materially tends to render the same comfortable in use. 7

I claim:

1. In a shoe, a heel structure comprising an upper member formed to be rigidly secured to the under side of the heel portion of a shoe, the forward edge of said member be ing formed to embody a groove designed for the snug reception of the rear edge of the shoe sole, an extension projecting downwardly from said member, a heel body having an internal socket arranged tov receive said extension, and a lower clamping meminternally threaded shank portion, a heel 5 body formed with a cup shaped upper portion for the reception and inc'losure of said upper member and with an internal socket for the reception of said extension, a clamping member fitted upon the lower surface of said heel body, and a threaded fastening ele ment carried by said clamping member and arranged to be received within the internally threaded portion of said extensionto maintain the heel structure in assembled con dition. r

3. In a shoe, a heel structure comprising a metallic base plate arranged to be rigidly secured to the under side of the heel portion of a shoe, a rigid extension depending from said base plate and having its lower end provided with an internally threaded socket, a heel member of substantially hollow formation arranged to receive and to surround said extension, a transversely extending rib formed upon the lower surface of said heel member, a-tread plate arranged to be fitted upon the lower surface of said heel member, said plate being provided with a transversely extendinggroove arranged for the reception of said rib, and-threaded means cooperative with said tread 'plate and arranged to be received within the socket of said extension to bind the various elements of said heel structure in assembled relationship.

In testimony whereof I aflix m signature.

FRAN SAHR.
