Application filed J' une 22, 1916. Serial No. 105,189.

To all whom t may concern Be it known that I, Ti-roMAs B. KEOGH, a citizen of the United States, residing at Bronx, New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Cushioned Heels; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to improvements in cushioned heels.

The object of the present invention is to improve the construction of cushioned heels and to provide a simple, practical and comparatively inexpensive construction adapted to be readily applied to various types of foot wear and capable of absorbing and dissipating shocks and of lessening the fatigue of walking and running and of minimizing the J With these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacriicing any of the advantages of the inven-l tion.

In the drawing Figure 1 is a vertical longitudinal sectional view of a cushioned heel constructed in accordance with this invention and shown applied to a portion of a shoe, Fig. 2 is a transverse sectional View of the same taken substantially on the line 2 2 of Fig. 1, Fig. 3 is a horizontal sectional view on the line 3 3 of Fig. 1, Fig. 4 is a detail view of the marginal cushioning spring, Fig. 5 is a vertical sectional view illustrating a modification of the invention, Fig. 6 is a'transverse sectional view of the same, Fig. 7 is a plan view ofthe metallic plate of the lower relatively movable heel section for interlocking the same with the headed stud.

Like numerals of reference designate corresponding parts in the several figures of the drawing.

In the accompanying drawing in which is illustrated the preferred embodiment of the invention, the cushioned heel comprises in its construction, a metallic shell 1 constituting the upper portion of the heel and consisting of a horizontal top plate 2 and vertical walls 3, the top plate being provided with suitable perforations for the reception of fastening devices 4 which secure the cushioned heel to a shoe 5 or other foot wear. The metallic shell telescopically receives a lower heel section G designed to be constructed of leather orother suitable material and cushioned by coiled conical springs 7 and a marginal spring S. lIhe upper and lower heel sections conform to the configuration of the conventional heel and the upper metallic heel section is equipped with a plurality of `depending headed studs 9 secured attheir upperends 10 tothe top plate 2 and extending downwardly therefrom and provided at their lower ends with heads 11. The lower' heel section is provided with vertical sockets 12 extending downwardly from the upper face of the lower heel section and receiving the headed fastening devices which are adapted to be engaged by a locking plate 13. The locking. plate 13 is constructed of suitable sheet instal and is litted in a recess or pocket 14 of the lower heel section and is provided with slots 15 and 1G which are adapted to receive the shank portions of the headed studs.

- In applying the locking plate the heel is forced inwardly suiiciently to compress the coiled springs which bear against the upper face of the lower heel section. The springs are compressed to cause the heads of the fastening devices to extend below the horizontal recess or pocket 14 and the locking plate is then inserted in the recess or pocket and engaged with the headed stud. By this construction the upper and lower heel sections are securely connected together and the locking plate is retained against accidentaldisplacement by a flange 17 formed integral with and extending downwardly from the front portion of the lockingI plate and secured tothe heel section 6 by suitable fastening devices 18. l/Vhen the heel is subjected to pressure the springs will be placed under tension and the cushioning action is increased by a marginal spring 19 constructed of resilient wire or other suitable material and composed of spaced sides and connected transverse portions as clearly illustrated in Fig. l of the drawing. The marginal spring is composed of reversely arranged approximately U-shaiped spring bends 20. The marginal spring conforms to the configuration of the heel and one` or more of the springs may be omitted to secure the desired cushioning action and the strength of the springs may of course be varied. The approximately U-shaped or V-shaped bends form oppositely inclined portions 2l and provide an edective cushioning device.

In Figs. 5 to 7 inclusive of the accompanying drawing is illustrated another form of the invention in which elastic cushioning sleeves 22 are mounted on the headed fastening devices instead of conical coiled springsand the lower section 23 is slidably interlocked with the headed fastening devices 24 being provided with substantially key-hole shaped openings 25 formed vin a metallic plate 26 which is mounted within the lower heel section 23. The sockets 27 of the lower heel section are elongated to enable the slotted locking plate 26 to be engaged with the headed fastening devices and the outer shell is preferably provided with lugs 29 which are bent around into engagement with the lower heel section to hold the same vagainst relative sliding movement. The cushioned heel shown in Figs. 5 to 7 inclusive is also provided with a marginal spring 19 and the said locking plate is preferably secured between the layers of lifts of the lower heel section.

The cushioned heel is adapted to be readily applied to a boot or shoe and by varying the strength of the cushioning springs and the number, thereof the desired resiliency and cushioning action of the heel may be obtained.

Vhat is claimed is 1. A cushioned heel of the class described including :an upper metallic shell, a lower relatively movable section provided with sockets and having a .pocket or recess intersecting the same, headed studs depending from the metallic shell and extending into the sockets, a locking plate removably arranged in the pocket or recess and interlocked with the headed studs, and cushioning devices disposed on the headed studsV and interposed between the lower heel section and the metallic shell.

2. A cushioned heel of the class described including an upper section, a lower relatively movable section, one of the sections consisting of a metallic shell and receiving the other section and a marginal spring interposed between the sections and composed of spaced sides and connecting transverse portions and consisting of a resilient piece of material bent to form reversely disposed spring bends of approximately V- shape.

3. A cushioned heel of the class described including an upper metallic shell having depending studs, a lower heel section slidably interlocked with the said studs, cushions arranged on the studs and interposed between the shell and the lower heel section and a marginal cushioning spring extending around the studs and consisting of a continuous piece of resilient material bent back and forth to form reversely arranged approximately V-shaped spring bends.

4. A cushioned heel of the class described including an upper inverted metallic shell, a lower heel section provided with elongated sockets and having a metallic plate provided at the sockets with substantially key-hole shaped openings, headed studs depending from the metallic shell and extending into the elongated sockets and interlocked with the key-hole slot, cushioning means interposed between the lower heel section and the metallic shell, and means carried by the metallic shell and engaging the lower heel section for holding the same against sliding movement.

In testimony whereof I affix my signature in presence of two witnesses.
