SHOE HEEL Filed Aug. 6, 1938 l l Inventor Jahn .aZZey/f Attorneys Patented May 23, 1939 UNITED STATES PATENT OFFICE 2 Claims.

This invention relates to that classification of appliances known as shoe heels, and has specific reference to an improved sectional construction wherein the chief novelty pertains to an assemblage of telescoping parts expressly devised and assembled to promote longevity and walking comfort.

The prior art to which the invention relates is well worked, active, and therefore characterized by innumerable sectional heel structures. It follows therefore, that my aim is to devise and provide the trade with a further specific contribution to this line of endeavor, and in so doing, to remain within the realm of simplicity and economy while at the same time offering the added feature of effectively cushioned walking comfort.

As the novelty on which the succeeding claims depend is structural in character, further objects need not here be enumerated. Manifestly, however, features and advantages arising from my specific adaptation and allocation of parts will become apparent from the succeeding description and claims.

In the drawing, wherein like numerals are employed to designate and differentiate like mechanical details:

Figure 1 is a View in section and elevation showing a portion of .a shoe equipped with the new sectional heel as developed and perfected in accordance with my idea.

Figure 2 is a horizontal section on the line 2-2 of Figure 1.

Figure 3 is a bottom plan view.

Figure 4 is a detail perspective drawing of one of the parts.

Reference being had to the drawing by distinguishing reference numerals, it will be observed that the relatively stationary part, which is of any appropriate material, is' denoted by the numeral 5 and this is fixedly mounted on the shoe 6. It is provided with a socket 'I to telescopically accommodate the relatively movable or slidable companion part 8. The latter part is the tread and may or may not be provided with extra cushioning lifts. Ordinarily, however, it is simply provided with a metal or equivalent heel plate 9. This serves to close in a pocket IB and when the plate is removed access can be had to a retention screw Il utilized to hold in place the stop washer to limit downward sliding movement of the part 8 relative to the part 1. 'I'he part 8 is of a cross sectional diameter to slide within the limits of the socket 'I and has a central bore. The bore is triangular in cross section to correspond to the triangular shaped assembling and (Cl. Sli-38) guide rod I2. At its upper end the rod I2 is fastened by a screw or the like I3 to the upper end portion of the socketed heel section 5. It will be observed too that the slidable heel section v8 is provided with an upstanding sheath I4 5 which surrounds the pin or bolt I2 and this limits the upward or inward sliding motion of the slidable heel section. A coiled spring I5 is confined in the socket and surrounds the sheath and bears at one end against the heel section 5 and at the opposite end against the heel section 8. This is the self-adapting cushioning and yieldable check means. It is to be observed that the pin or guide bar I2 is polygonal in cross section so as to prevent axial turning of the heel section 8. Moreover, it projects below the lower end of the open socket 1 to facilitate assembling of the parts. As said pin is a separate element it is susceptible of removal and replacement. The spring is also easily accessible and replaceable, and in fact, any one of the several parts, if and when worn, may be easily renewed. The main idea however, is to provide the telescoping complemental sections with the interposed spring and guide means, the sliding in opposite directions being limited, and the coaction being such as to provide a suitable Weight sustaining and elastic heel construction. Under this arrangement shocks and jars are avoided and it is virtually unnecessary to utilize rubber lifts.

It is thought that the description taken in connection with the drawing will enable a clear understanding of the invention to be had. Therefore, a more lengthy description is thought unnecessary.

While the preferred embodiment of the invention has been shown and described, it is to bev understood that minor changes coming within the field of invention claimed may be resorted to if desired.

I claim:

1. A sectional shoe heel comprising a relatively stationary main section having a socket, a depending detachable rigid pin arranged centrally in said socket and extending below the open bot- 4 tom thereof, said pin being polygonal in cross sectional form, a relatively movable section fitted telescopically for sliding in said socket, the bottom thereof being pocketed to facilitate assembling and maintenance on said pin, said movable section having a sheath and bore coacting in providing a guide passage for the pin, and a coiled spring surrounding the sheath and located in the socket and bearing at one end against the 55l fixed section and at its opposite end against the movable section.

2. A sectional shoe heel comprising a relatively stationary main section having a socket, a depending detachable rigid pin arranged centrally in said socket and extending below the open bottom thereof, said pin being polygonal in cross sectional form, a relatively movable section fitted telescopically for sliding in said socket, said movable section having a sheath and bore coacting in providing a guide passage for the pin, and a coiled spring surrounding the sheath and located in the socket and bearing at one end against the fixed section and at its opposite end against the movable section.

JOHN PALLEY.
