UNITED STATES PATENT OF ICE.

GEORGE \VASHINGTON BIDDLE, OF OENTRIALI A, ILLINOIS.

CONVOLUTE SPRING-HEEL.

QPECIFICATION forming part of Letters Patent. No. 349,683, dated September 28, 1886.

Application filed Apr i1 7, 1886. Serial No. 198,1-18. (No model.)

To aZZ whom it may concern Be it known that I, GEORGE WAsnINGroN BIDDLE, a citizen of the United States, residing at Gentralia, in the county of Marion and 5 State of Illinois, have invented a new and Improved Oonvolute Spiral-Spring Boot or Shoe .Heel, intended to be applied to all kinds and sizes of boots or shoes and to be used and worn instead of the leather or other hard heels now in general use; and I do hereby'declare that the following is a full, clear, and exact description of the invention, reference being had to the accompanying drawings, which will enable others skilled in the artto which it ap- I pertains to make and use the same. I

This invention relates to spring-heels for boots or shoes; and it has for its object to provide a spring lieel which will be light,

strong, durable, and cheap, and which will obviate the main objection to all spring-heels with which I am familiar-that is, their utter failure to compress or give equally on all sides when a pebble or uneven surface is stepped upon; and with this object in view the inven- 2 5 tion consists of the parts and combinations of parts hereinafter described and claimed.

In the accompanying drawings, forming a part of this specification, Figure 1 is a vertical sectional view of my improved heel at- -3 tached to a shoe, the counter of the latter being partly broken away to show how the heel is secured; Fig. 2, a plan view of the bottom, with top lift removed; Fig. 3, a perspective view of the base-plate, and Fig. 4 a perspec 3 5 tive view of the convolute spring forming the heel.

Similar letters refer to similar parts throughout the several views.

A represents the base-plate. This plate is made of any suitable metal, and is shaped like the lift of a heel,and is provided with perforations to at intervals around its edge,and has an extension or shank-piece, B, extending forward from the front or breast of the heel, which is also provided with perforations a, for nails or screws, as clearly shown in Fig. 3, to secure the same to the sole of the shoe. The edge of the base-plate A is turned up all around to form a groove, 1). The heel C is formed of a continuous spring-metal strip, formed the desired shape, the coils of which are convolved or rolled so as to fit within each other without binding, gradually becoming smallerin diame- I ter as the bottom of the heel is reached, and to the bottom coil the top lift,D,is brazed or otherwise secured so as to form a tight joint. The upper coil of the spring is turned outward, so as to form a flange, (I, which fits within the groove, I), to secure the heel to the base-plate A, where it is securely held by the metal cleat E, which is fastened to the base-plate'immediately in front of the heel, so as to abut against the san1e,by means of screws or in any other suitable manner. Within theheel Iplace oneor more volute springs, F, according to the weight of the person who is to use the heel, the smaller ends of the springs being. placed against the base-plate, so that they-will not interfere by binding or catching inthe coils of the spring forming the heel. These springs are not secured or fastened in any way within theh'eel,

and may be removed at any time for the purpose of substituting stronger or weak er springs therefor. The base-plate is first secured, by screws or otherwise, to the insole, the number of springs F desired having first been placed within the heel, the flange d is slipped into the groove b, and the cleat E fastened to the baseplate A, so as to prevent the heel-flange 4 moving forward and out of the groove. Thus it will be seen that I provide a heel the whole of which is formed of a spring-metal strip or bar, the main body of the heel being in one piece, which will not bindor catch when unequal pressure is applied thereto, while at the same time stronger or. weaker springs may be used with the same,to accommodate the differ- ,ent weights of the persons using them. This the heel may be removed in a very short space of time, when so desired.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A heel-shell for boots or shoes, formed 4. The hereinbeforedeseribed eonvolute spiral spring heel, formed of one continuous piece of spring metal, the top lift, D, the flange 11, 15 the perforated base-plate A, shank-piece B, groove b, springs F, and cleat E, substantially as set forth.
