To all whom it may concern.- leather-board, leatherette, or other suitable Be it known that I, JOHN S. DAMRELL, a material, and the purpose of which is to pro citizen of the United States, residing at Bosvide the sole with some degreeof stiffness ton, in the county of Suffolk and'State of Masand body. I prefer the buckram because it sachusetts, have invented a new and useful possesses a suitable degree of stiffness, is Improvement in Inner Soles, of which the fol light, ventilating, and flexible and readily and lowing is a full, clear, and exact description, continuously bendable without being weakreference being had to the accompanying ened. This section of the insole is located drawings, forminga part of this specification, upon the lower section A. IO in explaining its nature. 0 is the upper section of the sole.

I would mention as one compound a mixture of sulfur and bichromate of potash, which may or may not be perfumed.

The various sections A, I and G are of the same size and are united together by a common binding-tape H or other cloth, which embraces the entire outer edge of the sole and is united thereto by stitches, which pass through the edges of said sections.

While in the drawings the copper plate is represented as somewhat longer than the zinc, I would say that the zinc may be longer and may be extended from both ends of the copper plate into the fore part and heel part of the sole.

Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United States 1. A removable inner sole comprising two or more layers of flexible, material between which is located an electrical device shorter than the length of the sole, and a wire-gauze strip of substantially the length of the sole, in contact with said generator, and means whereby the edges of said sole are bound together, said generator serving to stiffen the shank of the sole and said gauze to distribute thecurrent from said generator over the interior of the sole, without unduly stiffening it, as set forth.

2. The improved removable inner sole consisting of a nu mber of layers of material united together, an interposed device for generating electricity, an interposed means for assisting in the distribution thereof throughout the same and a chemical compound for assisting in the generation of the electricity and also of a moisture-absorbent nature interposed between said layers.

3. A removable inner sole having a Waterproof under layer or surface and containing a layer of stiffening material, a strip of wiregauze extending the length of the sole above said stiffening material, an electric generator containing a strip of spring metal considerably shorter than the length of the sole and located in the shank thereof and in electrical contact with said strip of gauze, and an upper surface formed of flannel or other suitable material, said parts being bound together at the edge, whereby the generator is protected from moisture on the under side ofthe sole and the electricity generated thereby is spread throughout the surface of the sole and protected from the foot, and the Whole is bound together by stitching, as and for the purposes set forth.

JOHN S. DAMRELL.
