UNITED STATES PATENT OFFICE.

ALBERT S. DENNISON, OF WATERTOWN, NEW YORK.

GALVANIC HORSESHOE-PAD.

SPECIFICATION forming part of Letters Patent No. 229,103, dated June 22, .1880.

Application filed April 17, 1880.

'To all whom it may concern:

Be it known that I, ALBERT S. DENNISON, of Watertown, in the county of Jefferson and State of New York, have invented a new and valuable Improvement inGalvanic Horseshoe-Pads and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification,

and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a representation of a perspective View of my improved horseshoe-pad, and Fig. 2 is a longitudinal section thereof.

This invention has relation to horseshoe pads; and it consists of a pad composed .of zinc and copper strips united together and forming a battery, and placed with its zinc face next the hoof, whereby an electrical current is created that oxidizes the zinc and produces a healing effect upon a sore and tender hoof, as will be herei nafter more fully set forth.

In the accompanyingdrawings, the letter A designates my improved l1orseshoe-pad,composed of strips of zinc and copper cut into the form of a horseshoe and united together. The zinc plateds provided at intervals with perforations a, into which the metal of the copper plate overlying the same is punched down, as shown in Fig. 2.

This pad is placed upon the preparedhoof, the shoe laid over the same, and the whole fastened on by the usual nails, or it may be first secured to the shoe and the whole fastened to the hoof.

(N0 model.)

By the employment of this electric pad nature is assisted in keeping the extremities warm and causing the blood to circulate freelytherein. The blood-vessels of a horses extremities are of such small size that the blood-circulation seems to depend more upon capillary attraction than upon the force exerted by the heart, in order to permeate said vessels; hence the blood-supply is necessarily small and its flow very sluggish, and the value of the electric current in equalizing the heat and promoting the circulation is apparent.

Sometimes the shoe may be constructed in the same manner as the pad-that is, of strips of zinc and copper.

What I claim as new, and desire to secure by Letters Patent, is-

1. A galvanic horseshoe-pad consisting of a strip of copper and a strip of zinc cut into the shape of a horseshoe and united by punching the copper at intervals into suitable 'perforatious in the zinc, substantially as specified.

2. As a new article of manufacture, a horseshoe-pad composed of a strip of zinc and a strip of copper of a configuration similar to that of a horseshoe, the two being united together by suitable fastening devices, and the whole adapted to be secured between the shoe and hoof of the horse, substantially as specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

ALBERT S. DENNISON.
