warren RESILIENI BREAD MEMBER FOR BOOTS AND SHOES.

Application filed November 6, 1924, Serial No. 748,019. Renewed March 18, 1925.

This invention relates generally to resilient heels or soles for boots or shoes, the invention having for an object to provide a novel type of spring-mounted heel, whose yielding or cushioning movement may be varied.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the follow ing description and accompanying drawing, and to the appended claims in which the va rious novel features of the invention are more particularly set forth.

Fig. 1 of the drawing is a side view of a shoe having the invention applied thereto.

Fig. 2 is an underside plan view.

Fig. 3 is a fragmentary front view of the heel.

Fig. f is a central longitudinal vertical sectional View thereof.

Fig. 5 is a longitudinal sectional view taken on the line 5-5 of Fig. 3.

In the drawing the reference numeral 10 indicates generally the upper of a shoe, 11 the sole, and 12 the upper rigid portion of the heel. This heel portion 12 is formed on its underside with a relatively large recess 14; into which projects the top portion of the resiliently mounted heel element 15, this latter having a laterally projected peripheral flange 16 that underlies the edge of the heel part 12, Located in the recess 14. and hearing between the top wall of the latter and the top face of the movable heel element 15, is a coiled expansion spring 17 that serves as the cushioning means.

The heel element 15 is connected at its front end to the top heel portion 12 by a novel means that permits of the said heel element swinging on its front edge as a pivotal axis or moving in straight line .up and down. As here shown a bar 20 is located in a recess 21 in the front wall of the top heel.

portion 12, a pair of expansion springs 22 hearing on the rear face of this bar to urge These apertures 26 are formed at their rear ends with downward extensions 31 with wh ch the pin ends 27 register when the bar 20 is moved sufficiently forward. Threaded through the rear wall of the top-heel port1on 12 is a screw 33 that bears at its inner end on the inclined top wall of a recess 24 1n the lower heel element 15. By adjusting this screw the distance that the heel element 15 separates from the top heel portion 12 under the influence of thespring 17 may be varied.

As will be apparent, when the bar 20 is moved by the screw 23 to the rear side of the cavity 21 the pin ends 27 will have ahinge connection therewith, so that the heel element 15 will swing on its forward edge as a pivotal axis, while if it is desired to have the heel element 15 move bodily up and down the bar 20 is moved forwardly to allgolw the said pin ends to move in the oifsets T preferably make the sole of the shoe of resilient construction also, forming the same with a recess or cavity in which is mounted a spring 35. To conceal the space between the top and bottom heelportions a dependmg flange 36 may be attached to the said top portion and engage over the top part o the edge of the lower heel element.

Having thus described my invention, what I claim as new and desire to protect by 1Letters Patent of the United States is as fol ows:

1. In a shoe, a fixed top heel part having a recess in its underside, a movable lower heel element engaged at its upper side in said recess, a spring in said recess forming a cushion between the said top heel part and lower heel element, a bar extending transversely of the shoe in a cavity in said top heel part, said bar being adjustable transversely of itself and being formed with a pair of apertures, and pins fixed in the lower heel elements and having laterally projected top ends engaging in said apertures.

2. In a shoe, a fixed top heel part having a recess in its underside, a movable lower heel element engaged at its upper side in. said recess, a spring in said recess forming a cushion between the said top heel part and lower heel element, a bar extending transversely of the shoe in a cavity in said top heel part, said bar being adjustable transversely of itself and being formed with a pair of apertures, and pins fixed in the lower heel elements and having laterally projected top ends engaging in said apertures, said apertures having downward offsets at one end with which said top ends are brought into complete registry by rearward movement of said bar in said cavity.

3. In a shoe, a fixed top heel part having a recess in its underside, a movable lower heel element engaged at its upper side in said recess, a spring in said recess forming a cushion betweenthe said top heel part and lower-heel element, a bar extending transversely of the shoe in a cavity in said top heel part, said bar being adjustable transversely of itself and being formed with a pa r of apertures, and pins fixed in the lower heel elements and having laterally projected top ends engaging in said apertures, said apertures having downward ofi'sets at one end with which said top ends are brought into complete registry by rearward movement of said bar in said cavity, a screw bearing on one side of said bar, and a pair of springs bearing on the other side thereof.

4:. In a shoe, a fixed top heel part having a recess in itsunderside, a movable lower heel element engaged at its upper side in said recess, a spring insaid recess forming a cushion between the said top heel partand lower heel element, a bar extending transversely ofthe shoe in a cavity in said top heel part, said bar being adjustable transversely of itself and being formed with a pair of apertures, and pins fixed in the lower heel elements and having laterally projected top ends engaging in said apertures, and a screw threaded through the rear end of said top heel part and bearing on aninclined wall member on said lower heel element to limit downward movement of the VENDEL MR5, V
