. PatentedSept. 15, 1914 Application filed March 17, 1914. Serial No. 825,279. I

To all whom it may concern:

Be it known that we, CHARLES Burner and Jzsnr SznNAsI, subjects of the King of Hungary, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Spring-Heels for Boots and Shoes, of which the following is a specification.

This invention relates to new and useful improvements in spring heels for boots and shoes.

The primary object of this invention is to provide a heel structure that is easy and cheap to manufacture and which is efficient in cushioning the foot of the wearer against the ordinary jar and shock incident to walking. 7

A further object is to provide a hollow heel upon ashoe having a resilient member removably positioned therein and entirely protected from the weather as well as hidden from view.

A still further object is to provide a shoe heel which shall have the ordinary finished external appearance but which at the same time will be metal-spring mounted for cushioning the shoe.

WVith these general objects in view and others that will appear as the nature of the invention is better understood, the same consists in the novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings and pointed out in the appended claims.

In the drawings forming a part of this application and in which like designating characters refer to corresponding parts throughout the several views: Figure 1 is a perspective view of a shoe showing the heel partially broken away and formed of the present improved structure. Fig. 2 is a vertical central view taken through the heel portion of the shoe illustrated in Fig. 1. Fig. 3 is a horizontal sectional view taken upon line 3-3 of Fig. 2, and Fig. 1 is a plan view of one of the spring attaching plates of the heel.

Referring more in detail to the drawings, the shoe 10 is illustrated as provided with a heel formed of a tread member 11 secured to the heel portion 12 of the shoe sole 13 and spaced therefrom by means of a flexible sheet 14: and thereby providing a heel inclosure or chamber 15. Plate members 16 preferably formed of metal and having struck up circular central portions 17 are secured tothe opposite faces .of the block 11 and heel portion 12 of the sole while their portions 17 are extended toward each other. Annulus blocks 18 are mounted over the plates 16 and surrounding the struck up portion 17 thereof and are secured through said plates by suitable hold-fast devices 19 to the adjacent supporting members which are the blocks 11 and sole portion 12. Fora cushioning means a coil spring 20 is provided within the chamber 15 and having its extremities passed through the openings 21 in the oppositely positioned plates 16 and removably secured to such plates by a slight rotation of the spring ends beneath the struck up portions 17 thereof. The spring being thereby secured between the struck up portions 17 of the opposite plates 16 seats upon and around such struck up portions which latter thereby provide a centering or positioning means for the spring. From this it will be evident that the spring is readily attached to the opposite plates 16 and has its ends seating adjacent the struck up portions 17 while the annulus members 18 surround the end portions of the spring and reinforce the flexible covering 14 which.

is suitably secured thereto, and the traction block 11 engages the ground in the walking operation while the spring cushions the jar of walking and is entirely hidden from view by the flexible covering 14 forming a chamber 15.

While the forms of the invention herein shown and described are what are believed to be preferable embodiments thereof, it is nevertheless to be understood that minor changes may be made in the form, proportion and details ofconstruction without de-' parting from the spirit and scope of the invention as set forth in the appended claims.

What is claimed as new is:

1. The combination with a shoe sole, ofa

spring-heel, plates formed with confronting struck-up portions, each having a perforation, blocks conforming to the shape of the heel and secured respectively to the sole and lower lift or tread of the heel to secure said plates in position, a coil spring having the ends of its upper and lower convolutions secured in said perforations, and a flexible sheet connecting said blocks and concealing said spring.

2. In combination a sole and a tread member having a chamber therebetween, struck up circular plates secured to the adjacent faces of said tread memberand sole In testimony whereof We afiii; our signaand having peripheral perforations there- I tures in the presence of two witnesses.

through, a helical spring seated between said CHARLES BUDAI struck up portions of said plates and having its ends passed beneath said struck up por- V JOZSEF SZLNASI- tions, and blocks mounted upon said plates Witnesses! and'encircling said spring ends and struck JOHN VASZI,

up portions. G. VAJDO PETER.
