ELASTIC OR ANTICONCUSSION HEEL AND SOLE FOR BO TS, &c.

SPECIFICATION forming part of Letters Patent No. 532,429, dated January '8, 1 895 Applica n fil January 2, 1894. Serial No. 495,464. (No model.) Patented in England October 9, 1893, No, 18.921; in France December 9,1893,N0. 234.68 7, and in India July 23, 1894, No. 276. I

To ctZZ whom it may concern.-

Be it known that I, LESLIE Roenns, a subject of the Queen of Great Britain, residing at Dehra Doon, India, have invented certain new and useful Improvements in Elastic or Anticoncussion Heels and Soles for Boots or Shoes, (for which I have received Letters Patent in Great Britain, No. 18,921, dated October 9, 1893; in France, No. 234,687, dated fied, elastic, flexible or yielding cushions, pads der surface.

or air cells of an improved construction, and arranged in an improved manner upon which the heel and ball of the-foot of the wearer may rest, and thus deaden, prevent or reduce concussions, jars or shocks, as herein set forth.

In the accompanying drawings,Figure 1 represents a bottom, plan view of my im-.

proved in-sole; Fig. 2, a top plan view thereof, and Fig. 3, a vertical, central section.

The drawings show the heel pad A, as provided with polygonal air cells a a on its un- The central cells a, are .shown as of larger size than the outer; ones a, the tendency of which construction will be to allow greater elasticity or range of movement of the central portion.'

As shown in Fig. 3, the central cells are deeper than the marginal ones, thus making the pad convex. By this arrangement, it will be seen, that thepads are composed of air cells which are not meant to collapse nor sustain the pressure of the foot on ridges or on solid projections, but an air cushion is provided, the pressure of the foot compressing the air in each separate cell, but will not col- The walls of the air cells being hexagonal, as shown, much less room in a given space is taken up, and the strong* est arrangement for the purpose required is afforded. The cells with the air inside are intended to support the weight of the foot, and yet to be sufticiently pliable and cushion-like to prevent jars and concussions to the foot. The heel pad is also shown as provided with a peripheral flange a through which the stitches or fastenings which secure it to the sole are made. I

The ball pad B, and its cells I), may be made and applied likethe heel pad with the necessary changes in form to adapt it to the different conditions of its use. As shown, the ball pad consists of a cellular strip arranged diagonally to conform -to the shape and inclination of the ball of the foot. The cells I) are approximately of the same size as the small cells a in the heel pad. The pad B, is convex like the pad A, as shown in Fig. 3.

Both the heel and ball pads are secured to an in-sole of flexible material, as indicated, which may be readily inserted in a boot or shoe. It may be made of india rubber, gutta percha, or other suitable material, or partly of these substances and partly of cloth, cork, "felt, Eatlrm, or like material. In any event, however, the heel and ball pads should be made of elastic material and secured to the backing or in-sole in any suitable way. The walls of the air cells on their under side lie close to the top of the sole of the boot or shoe, and are thus practically closed, so that the air cells are closed or nearly closed, and the pressure of the foot acts not so muchto flatten out the walls of the cells as to expand and contract the air in the cells-in fact, acting as if the cells were closed air-tight, they being so nearly completely closed as to make the escape of air slow.

I claim as my invention- 1. The heel pad herein described, constructed'with an elastic body provided with two sets of air cells a a, having flexible or elastic hexagonal walls, the central set of cells a being larger than the outer cells a, for the purpose specified.

2. The heel pad herein described, constructed of elastic material having the central air cells, and the outer air cells, with walls shallower than. the Walls of the central cells, thus forming a convex pad.

3. The heel pad herein described, constructed of elastic material having the box agonal air cells, the walls of which are shallower at the edges than at the center, in combination with a ball pad constructed of elastic material having hexagonal air cells, the walls of which are shallower at the edges than at the center, said ball pad being arranged diagonally to conform to the shape of the foot, the portions of the sole between the heel and the ball pad, and between the ball pad and the toe, being unoccupied by cells, substantially as described.

4. The heel pad herein described eonstrncted with a multiplicity of air cells, terminating at the edge of the heel, in combination with a diagonally arranged ball pad con-
