SEECFC-.TION forming part of Let-ters Fatemi; No. 745,798, dated December 1, 1903.
Application filed July 16,1902. Serial No. 115,793. (No model.)
To will whom t may concern:
Be it known that I, WILLIAM C. CORMAN, a citizen of the United States, residing at Rochester, in the county of Stratford and State of New Hampshire, have invented new and useful Improvements in Elastic Pads for Heels, 'of which the followingis a full, clear, and eX- act specification.
This invention relates to rubber pads adapted to be secured by screws or nails to the under side or bearingsurface of the heels of boots or slices either by the consumer (wearer) or by a Shoemaker.
The invention relates particularly to that class ot' elastic rubber heel-pads which may be termed pneumatic padsthat is to say, pads formed with a recess or chamber containing air, thereby supplementing the elasticity of the rubber with an air-cushion.
The nature ot the invention is fully described below, and illustrated in the accompanying drawings, in which- Figure l is a plan View of the inner or u, per side of my improved elastic heel-pad. Fig. 2 is a central vertical sectionof the same attached to a heel, the heel and a portion of the shoe being also shown in section.
Similar letters of reference indicate corresponding parts.
The pad is formed of an integral piece of rubber of suitable softness and elasticity. It is made somewhat smaller in area than the surface of the heel to which it is to be applied, and it comprises the central downwardly or outwardly projecting and comparatively thin concavoconvex portion d, corresponding substantially in shape to the periphery of the pad; a ledge or step b somewhat higher than the portion o, and surrounding said portion, said ledge being preferably concave in crosssection; blocks or supports d, extending up from said ledge, having flat tops, and being' of even height, and a comparatively thin peripheral lip or flange c, which extends normally upward and in line with the edge of the pad. Suitable holes g are provided, through which screws or nails may be driven for the purpose or" attaching the' pad to the heel, and as screws are preferable i provide nuts 7L at the screw-holes during the process of vulcanizaticn, the use of such nuts being not new, however, in 'this invention.
lVhen the pad is applied to the heel, as shown in Fig. 2, and is screwed tightly into position, the iiange or rim e is flattened outward against the under side of the heel 7o and the heel rests upon the blocks d. Thus not only is a tirm support provided for the heel, but the flattened lip or ange makes a tight joint, so as to provide an efficient air-cushion in the chamber n between the portion o, and the heel. As th'e wearer walks the downwardly-protruding concavoeconvex portion a is pressed up and the air-cushion thus brought into use. By this means the wearer is provided with an elastic heel-pad in which the elasticity of rubber and air are both utilized and which can readily be applied or removed without necessarily employing the services of a shoemaker. Moreover, the pad may be applied to any heel that is sufficiently greater in area than the pad to allow the flange e to be pressed and spread outward without eX- tending beyond the edge of the heel.
The width of the liange orlip maybe somewhat varied, but should always be sufficient to provide a frictional surface which will adequately furnish an air-tight joint.
Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is
A rubber pad for the heelsV of boots and shoes comprising a central concave-convex portion provided with an upwardly-extendingledge surrounding the concave portion, a flange surrounding the lledge, the ledge also having a convex lower surface and a concave upper surface, and blocks formed integral with the iiange and concave surface, having ilat upper surfaces, said blocks being arranged at the opposite corners of the concaved portion of the pad and at the central rear portion and also at the side portions thereof, substantially as speciied.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
YJILLIM C. CORMAN.
