SPECIFICATION forming part of Letters Patent No. 430,048, dated June 10, 1890.

Application filed July 19, 1889. Serial No. 318,063. (No specimens.)

- will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to medicated cloth to be used as bandages, pads, sweat-collars, and the like; and it consists in the novel means,hereinafter specified, for incorporating oxide of zinc in a powdered form into textile or other fabrics, substantially as specified and claimed.

In carrying out my invention I take wool, cotton, hemp, jute, or otherraw material and sprinkle it with finely-powdered oxide'of zinc and then shake and stir the mass until the powder is infused and spread thoroughly on all the fibers. The proportions used may be varied in accordance with the amount of medication desired to be incorporated in the fabric; but I usually mix about one ounce of zinc with one ounce of the fibrous material. After the fibrous substances have been thus impregnated with oxide of zinc I spin and weave the same into cloth and it is ready for use.

Felt cloth is medicated by mixing powdered oxide of zinc with the shoddy of which it is manufactured in the same manner in which the fibrous materials are impregnated, as above described. Cloth, either textile or felt, thus medicated is found to be of greatvalue when used as bandages, pads, &c., either for man or beast. It prevents soreness, allays fever in sprains, bruises, sores, and wounds, and serves generally as a soothing remedy for all such difficulties.

Inasmuch as oxide of zinc is insoluble, the cloth described will usually retain it until worn out without regard to the amount of perspiration and even of washing, it may be.

Having described my invention, what I claim is The medicated cloth herein described formed of raw materials that have been impregnated with powdered oxide of zinc, substantially as specified.

In testimony whereof I afiix my signature in presence of two witnesses.
