ELECTRIC SOLE.

SPECIFICATION forming part of Letters Patent No. 360,127, dated March 29, 1887.

Application filed August 30, 1856. Serial No. $112,185.

To all whom it may concern.-

Be it known that I, FRANCIS B. WALLIS, of Everett, county of Middlesex, and State of Massachusetts, have invented an Improvement'in Electric Soles, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

rIhis invention has for its object to provide an electric sole,77 so called, which may be either permanently connected with or detachably placed within a boot or shoe, or other article of foot-wear, or Wearing-apparel.

The invention consists of an electro-therapeutical appliance constructed substantially as hereinafter particularly setforth and claimed.

In the drawings, Figure l shows in top view a sole embodying this invention, the perforated top piece being removed. Fig. 2 is a. plan of the perforated top piece detached, and Fig. 3 is a vertical crosssection of a sole constructed in accordance with my invention.

A bottom layer or sole, A, upon which the permanent parts are placed, is made preferably of water-proof material, and cut tothe desired shape. Upon this layer or sole is arranged in alternation a series of copper and zinc rings, (t b, which rings Overlap, and a a piece of absorbent material, c-such as spongeis placed within the central opening of each of the rings, to absorb moisture from the person, to-assist in producing galvanic action, or a current between the person andthe metal plates. Additional voltaic 'couples may be had by means of copper and zinc strips d d', connected to the rings a b, of opposite polarity, and arranged substantially as shown.

A perforated thin layer or sole, B, of sheepskin or other suitable material, is then placed upon the metal rings and strips and the sole A, thereby concealing them and presenting a smooth surface for the person, the perforations 2 and 3 made in such sole B permitting the 4 moisture from the person to pass freely through to and be absorbed by the absorbent material c. It is obvious that, instead of making the (No model.)

parts a b as rings, they may be of any other desired shape; and also, instead of placing the absorbent material at the central openings in the rings it may be placed at any other convenient point.

If desired, felt or any other bibulous material may be employed as the absorbing material.

rllhe sole, constructed as described, may be permanently attached to a boot or shoe as an inner sole, or it may be employed as a socksole, to be introduced when desired.

A small quantity of dilute acid may be supplied -to the absorbent material, which, mingling with the moisture from the person, increases the current.

Vhat I claim isl. An electrotherapeutic appliance composed of a layer or sole, A, a series of overlapping copper and zinc disks placed thereon, absorbent material, as described,placed in contact with the batteries and suitably saturated with acid, and a perforated top layer or sole, B, substantially as set forth.

2. An electric sole composed of a layer or sole, A, a series of overlapping copper and zinc disks placed thereon, absorbent material, as described, placed in contact with the disks, the metal strips d d', coupled with the disks, aud the perforated top sole, B, all substantially as set forth.

3. Au elcctrotherapeutic appliance cou sisting of a layer or sole, A, a series of voltaic couples consisting of overlapping metal rings and metal strips connected thereto, absorbent material placed in connection therewith, and a perforated top layer or sole, B, substantially as described.

In testimony whereof I have si gued my name to this specification in the presence of two subscribing witnesses.

FRANCIS B. VALLIS.
