To all whom it may concern:

Be it known that I, .lomos Wrricowsxr, a citizen of the United States, residing,r at San Diego, in the county of San Diego and State of t`alifor1iia..'hnve invented certaiunewand useful Iniprowulents in Cusbion-Heels, of which the following is a specitication,.referenee being had to the accompanying drawing.

My invention relates to improvements iu heels for boots, shoes and other articles of footwear, and purticularly to heels oi greater resiliency or spriuginess than the ordinary leather heel.

One. object o f my invention is to provide a heel of.

the class described which will take the placeI of the It has bee-u found that heels of pure rubber soon wear out, and such heels cannot be repaired but must be thrown away after use. My new cushion heel reduces the concussion to the saine extent as does the best rubber heels made today and at the saine time it will outlast several pairs of such rubber heels and will be more noiseless than the ordinary leather heel. l

Another object of my invention is to provide a eushion heel which may be readily repaired. My new heel requires neither the services of n Shoemaker nor the use of hammer and nails. It is necessary only to unscrew and remove the piece of leather which forms the weer surface and to replace the worn one by a new one which may be purchased cut to size at any shoe-store.

Other features oi my invention will be pointed out hereinafter. i

In the drawings illustrating the principle of my in vention and Vthe best Inode now known to nie of apply ing that principle, Figure l is a perspective view ol my new cushion heel, Fig. 2 shows thc inside ply or layer and the loyer of rubber assembled; Fig. 3 shows the outside ply or the wear snr-inve und the springplate assembled; Figs. 4, 5, (i, und 8 illustratie details or parts of the heel; ind Fig. 9 is u sectional detail u the holes b; and ueutrully mounted upon the layer a is a. block of leather c formed with screw-holes d and nail holes e. Through the latter are driven nails which fasten, the block c and lift a to the solo A of thelshoe.

Passing downwardly from the sole of the shoe, the next layer niet with is the layer of rubber f (Fig. 5) formed with a central aperture y and with holes h which serve to give lightness to the rubber cushion and to save material. The rubber cushionf is further formed with unil holes t' which register with the nail holes b iu the leather loyer a and which are each provided with a. small washer the'centralA aperture in which registers with the nail hole. The central aperture g is so shaped that within it ts snugly the block of leather c, and the layer a and the rubber cushion f are assembled as shown in Fig. 2, the nails passing through the nail holes '5,1'

washers j and nail holes b serving to secure the two layers to the sole of the shoe, as well as tosecure the two layers together. I

Over the layer of rubber f is placed a plate l: of thin spring steel of a thickness of, say, one thirty-second of au inch. This plate. l; consists of a rim portion m and a. central portion vn connected to the rim by ribs o. The central portion f n is formed with large screw-holes p adapted to register with the screw-hoes d in the leather block c mounted on the layer a (Figs. 4 and 6); while the rim portion m. is formed with small screwholes w adapted to engage ythe shank of the screws q which secure the outer or wea-r loyer s to the spring plate k. The layer s'is shown detached in Fig. 7; and around the outer edge of its outer face :ne driven slugs r to resist the Wear which falls naturally upon this part of the heel and tends to malte it rn down. The screws q pass through the screw-holes p and d and secu. the spring plate l: to the leather block c. rIhus, the rubber cushion is held between thespring-plate la and thel inner lift a. l v

`The outer layer s formed with a central aperture t and in this aperture is forced a rubber plug or insertion piece u shown detached in Fig. 8. The edges of the plug u are beveled, as shown, and thus the plug is made v to fit snugly in tlie aperture t. The plug 'it covers the screws q and serves to keep mud and dirt out if the aperture t. By ilu-ans of the screws q the wear lii a is secured to tho/spring plate lc; and these two parts are shown assembled in Fig. 3. When the wear lift s is worn out, the. screws q are loosened and the old wear lift replaced by a new one procured at any shoe store. Thus, no skilled help is needed to repair the heel und the operation requires very little time and the use of no tool other thun a common screw-driver, or a device which will serve the purpose thereof. i
