RUBBER HEEL.

SPECIFICATION forming part of Letters Patent No. 736,394, dated August 18, 1903. Application filed June 12,1902. Serial No. 111,361. (No model.)

To all whom it may concern.-

Be it known that we, FRANK M. HILTON, JOHN S. HILTON, and WILLIAM W; HILTON, citizens of the United States, residing at Akron, in the county of Summit and State of Ohio, have invented certain new and useful Improvements in Rubber Heels, of which tween layers or plies of rubber comprising the heel, said frame having a cross-piece and corner extensions, the latter being bent to confine the corner portions of the heel.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for efiecting the result reference is to be had to the following description and drawings hereto attached.

While the essential and characteristic fea-' tures of the invention are susceptible of modification, still the preferred embodiment of the invention is illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of a rubber heel embodying the invention, parts being broken away. Fig. 2 is a top plan View, a

portion being broken away to expose the embedded metal frame. Fig. 3 is a section about on the line X X of Fig. 2. Fig. 4 is a top plan view of a modification, the upper portion of the 'heel being broken away to expose the metal frame.

Oorresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The heel 1 may be of any size or form, according to the style of boot or shoe for which it is designed,and may be solid or 1aminated,and

tion of the boot or shoe is made concave or depressed to conform to the convexity of the heel portion. of the shoe, so as to insure a close fit between the rubber heel and the corresponding part of the shoe when the heel is fixed thereto.

The metal frame 2, embedded in the heell, is approximately of D form, corresponding to the outline of the heel, and may be stamped from heavy sheet-iron or thin sheet-steel or formed in any desired manner. This frame is embedded in the heel 1 and is provided at intervals-in its length with openings 3 for the reception of nails or other fastenings employed for attaching the heel to the shoe. A brace extends across the space circumscribed by the frame and may be of X form, as shown at at in Fig. 2, or may be a straight bar, as shown at 5 in Fig. 4. The center of the brace is perforated to receive fastenings, whereby the central portion of the heel is confined to the shoe, thereby preventing suction when the heel is in service, and which feature is objectionable, since it draws moisture and foreign matter into the space between the heel and shoe, to the inconvenience and annoyance of the wearer, the resultant dampness keeping the feet cold and wet. suction is wholly obviated by the present invention. Hence moisture is excluded from between the heel and shoe, and no foreign matter, such as mud and sand, can find .its way between the heel and shoe. The corners of the metal frame are extended, as shown at 6, so as to support the corners of the rubber heel and hold them close against the shoe, These corner extensions 6 are bent upwardly slightly, so as to confine the corner portions of the heel against the sole of the shoe when the heel is properly attached thereto;

The metal frame 2 may bemolded into the heel or embedded therein in any manner, according to the method employedof forming the heel. In the event of the heel being a composite structure and built up of layers, plies, or laminae, the metal frame is confined between adjacent layers and the layers or This laminae vulcanized, so as to produce a substantial article.

The heel is placed upon the market in different sizes and shapes and is affixed to the shoe by driving suitable fastenings through the heel and the openings 3 of the metal frame, the heads of the fastenings coming in contact with the said frame and holding the heel in place. The nails may be of the clencher type, or screw-fastenings may be employed for attachment of the heel to the shoe.

Having thus described the invention, what is claimed as new is In a device of the character described, a rubber heel, a metal frame of approximately D form entirely embedded therein, a brace extending across the space circumscribed by the frame, an opening in the center of said brace adapted to receive a fastening where- FRANK M.
