My invention has reference to improvements in the heels'of boots or shoes, and more particularly to improvements in cushion heels such as are usually made of rubposition. a

, In nailin rubber heels to the leather heels or hee bases of shoes cement is com-' monly used, in addition to the attaching nails, to secure a tight joint between the expensive,

i the rubber heel retards the progress of tried to use plates conforming more or less isfactory product.

to the size and tending throughout a meat ereof. Such shape of the heel and exlarge'portion of the lates are wasteful of material and prohi itively expensive to manufacture; furthermore, they interfere with the desired cushioning'a'ction of the heel.

It is the object of my invention to provide an improved rubber heel by which the drawbacks above enumerated are eliminated. In the accomplishment of this object I have produced a rubber heel which may be quickly, firmly and tightly secured by nails or the like without the use of cement, which will permanently maintain a tight joint with the leather heel or base to which it is secured and which may be readily manufactured so as to produce a practical and sat- In the illustrated embodiment of the invention these desirable results are secured by embedding in a rubber' heel stifiening and supporting means comprising isolated fastening members of relatively small dimensions, as compared with the size of the heel, which are entirely unconnected and substantially separated .the portions of the heel immediately surrounding them is preserved under var ing conditions of shrmka eor distortion. 0 the heel as a whole. Said members may advantageously be made of spring material andco-operate with certain of the heel attaching nails to eflect a secure and accurate attachment of the heel, particularly at its-breast For the purpose of facilitating an'understanding of the features and advantages of the inventlon one satisfactory practical embodiment thereof is described in detail'here-f inafter and illustrated in the accompanying drawings, in-which- Fig. 1 is a plan view face of my improved rubber heel and indicating the embedded spring fastening and supporting members in dotted lines.

The rubber heel 10 has embedded in it adjacent to each breast corner an isolated stiffening and supporting element 12 .which may conveniently be mad spring steel and, in the illustrated embodiment of the invention, is shown as including twoportions disposed at an angle to each other and approximately L-sha d. Each of the members 12 pe has a single nail hole 13 and arms 14, 14 extending at right angles to each other therefrom, each of said arms having a slot 15; 1 As shown in Figs. 5 and 6 the arms Mare curved vertically. The

member 12 as shown in-F-i s. 1 and 3 has a p, I p

e of.

pro'ecting'an lar corner portion which exten from t e breast corner nailing location outwardly and forwardly into the breast corner of the heel further than it extends inwardly of the heel from said nail.

also in the rear portion of the I heel is an afiproximately-u-shaped member 16 having c aracteristics substantially similar to those of the members 12. The mem ber 16 is provided with a single nail hole 17; and forwardly extending arms18 which may be curved, ad shown inFi 8 and .9. The-t arms 18 are provided wit- 'slots 19whiela;

' tin'ough-them, thus'afiording a. firm and perare also disposed at an angle to each other, as shown in. Figs. 1, 3 and The slots permit the rubber to unite manentanchorage in the heel for the spring membemand they also facilitate the proper placin' and supporting of the members-"in the mo d' during manufacture. They also receive some of the attaching nails 20.

' When the attaching" nails are driven home their heads engagethe members 12, 16, .placing the spring arms in a permanent state of tension'and holding the rubber heel tightly It should be, understood that it is within the scope "of the invention to use stiffening and supporting inserts of shapes difierent from those employed in the particular embodiment of the invention illustrated herein and that, while three such inserts are herein illustrated, a di'flerent number may be used without departin from the invention.

Having described my invention, what I T claim asnew and desire to secure by Letters Patent is v 1 1; A rubber heel, having .a plurality of spring fastening means for securing the rubberheel under spring tension to the heel of; a shoe, or the like,- said spring fastening means consisting-bf L-shaped spring fastening members embedded in and adjacent to;

the corners of the rubber heel each havinga nail hole, curved spring arms and slots in the spring arms through which the rubber unites, anda U-shaped spring fastening member embedded in and adjacent to the a rear end of the rubber heel and having a .nail hole, curved sprin arms and-slots in the spring arms throng which-therubber unites, all for the purpose as described.

2. In a shoe, a cushion heel attached by fastenings, including a nail in each breast corner, Silld heelhaving embedded in each breastcorner' an isolated'stifl'ening and supporting member extending outwardly from the respective nail toward the adjacent corner of the heel materially further than it extends inwardly of theheel'from saidnail.

3. A' cushion heel adapted for attachment without cement,'compr1sing a heel having an isolated L-shaped supporting element in each breast corner, each of said supporting elements-having its angular portion extending toward the breast c'ornenofthe heel from the nailing location nearest to-said breast corner.

4. A'cushion heel containing adjacent to each breast corner, a resilient tensioning member, the tensioning members extending longitudinally of the heel and being entirely' isolatedv from each other, whereby their relation to the portions of the lleel immediately surrounding them is preserved under varying conditions of shrinkage or distortion of the heel as awhole.

5. A cushion heel having in each breast corner an isolated insertincl-uding two approximately horizontal arms, one extending transversely and the other extending longi- I tudinallyof the heel.

6 A rubber'heel having separate, unconnected tensioning members embedded therein adjacentto the breastcorners of-the heel, each of. said-'-members havinga single nail hole and-n *slettherein.

, 7.:A cushion heel having separated, un-

tending in the" rection of its side edges and adjacent ,thereto -said members occupying the gion ofthe-breast'corncrs only of the connected, elongated; stifiemng members 'exheeL- .r
