Specification of Letters Patent.

Patented June 25, 1907.

Application filed January 10,1907. Serial No. 351.580.

T0 LZZ whom, 25 may concern.-

Beit known that I, DAVID R. OvERMAN, a citizen of the United States, and aresident of the city of St. Louis and State of Missouri, have invented a new and useful Improvement in Electromedical Appliances, of which the following is a specication.

This invention relates to electro-medical appliances and particularly to pads used as an adjunct to the medical treatment for liver and kidney diseases, andA constitutional and nervous ailments resulting from such diseases.

It has for its principal objects to produce a combined medical and electro-galvanic pad which is simple and effective, which can be easily cleaned and medicated; and to attain certain advantages hereinafter set forth.

The invention consists in the parts and in the arrangements and combinations of parts hereinafter described and claimed.

In the accompanying drawings which form part of this specification and wherein like symbols refer to like parts wherever they occur, Figure l is a view showing the manner in which the pad is usually applied, Fig. 2 is a view of the pad showing the cushion side; Fig. 3 is a view, of the opposite side with portions removed to show the interior arrangements and, Fig. 4 is a section on line 4-4 of Fig. 2, on an enlarged scale.

The pad comprises a cushion 1, preferably lambskin 2 prepared with the wool thereon. A backing-sheet 3, preferably soft skin or leather, is stitched or otherwise secured at its side and bottom edges to the lambskin 2, thus forming a pocket having its opening at the top. Within this pocket is provided a lining of material which is impervious to moisture. Preferably, this lining is composed of two sheets or layers of material. The outer sheet 4 is waterproof sheeting and the inner sheet 5 is rubber. Obviously, however, the lining may be made of any other suitable material.

A plurality of Zinc disks 6 are secured within the pocket. These disks are provided with central apertures to receive headed copper rivets 7 The rivets are passed through the lambskin 2 through the interposed pocket sheets 4 and 5; and through the apertured disks 6 and upset upon a washer 8. Oopper disks 9 are placed adjacent to the Zinc disks 6 but spaced therefrom. These copper disks are fastened in position with copper rivets in amanner like the Zinc disks. The number ofdisks, both copper and zinc, depends upon the required strength of the battery. A removable absorbent cloth or pad 10 is placed in the pocket in contact with the disks 6 and 9. When the pad is saturated with vinegar or acidulated water an electro# galvanic action is set up through the Zinc disks and copper disks and rivets.

The device may be provided with a securing belt or straps l 1 as shown in the drawings, or, if desired, it may be extended into a complete girdle or belt. v

The pad is especially designed as an adjunct in the local treatment or application to the sacral plexus of nerves belonging to the great sympathetic system through which the cause of the diseases herein enumerated is reached. Its medicinal value is derived from the medicaments with which it is medicated. The wool is first combed and brushed until it is as fine and soft as fur, and then medicated according to a plan to suit each individual case. The medications are renewed daily or at such intervals as necessary. The pad is applied over the regions of the kidneys, liver, and the said Hsacral plexus.

By constant warmth and gentle friction from the wool, aided by the galvanism, the curative effect of the medications is very much accelerated. That the pad possesses peculiar intrinsic qualities inherent in the lambswool, and that the galvanism becomes effective through the lambswool when it has been medicated and becomes moistened from the exhalation from the body, has been demonstrated beyond doubt.

Obviously` other material may be substituted for the lambswool and the device is capable of considerable modiiication within 9 the scope of the invention. Therefore, I do not wish to be limited to the specific construction and arrangement shown and described.

What I claim as my invention and desire to secure by Letters Patent is:

l. A pad comprising a cushion of soft leather prepared with wool thereon, a pocket attached to said leather, said pocket having a lining of moisture-proof material, and an electro-galvanic battery within said pocket, said battery having terminals extending into the wool of said cushion.

2. A pad comprising a soft fibrous cushion, a pocket of material impervious to moisture,



tends into said fibrous cushion, and an absorbent pad in said pocket in Contact with said zinc and copper disks.

In testimony whereof I have signed my naine to this speciiication in the presence of two subscribing Witnesses this 2nd day of January, 1907, at St. Louis, Mo.
