    Specification. 3 A.D. 1871.—1460. JPulvermacJier^8 Impts, in the Construction of JElectric Chains, Bands, ^c. The second part of my Invention relates to making magnetic hands, belts, and garments to he worn or applied to the body in a similar manner and by similar means to those referred to in the first part, whereby a gentle self-sustaining magnetic action is kept up on the affected 5 parts, or throughout the whole body. I sew or otherwise secure thin plates, strips, or other pieces bent or not of magnetized steel, hardened, tempered, or annealed, in or to a fabric or web in sections, each section being composed of four, five, or more pieces in direct contact, to form compound magnetic staves or elements, and these may be connected to ' 10 other similar elements in any convenient manner, so as not to interfere with the movements of the wearer. The third part of my Invention consists in making bands, belts, and garments of a combination of elements such as those described in the first and second parts before referred to in order to produce combined 15 electrical galvanic and magnetic action. The fourth part of my Invention relates to certain improvements in the construction and form of the bands referred to in my previous Patents Nos. 2656, ; 773, and 2740, whereby I overcome many difficulties of manufacture, and make them more beneficial in use. 20 I propose to construct the bands of elements formed of two wires, say copper and zinc, wound side by side upon a mandril of such a shape as to make one side of the band plain and flat, to be applied to the body, and the other with one or more projecting portions to form channels to permit of sponge, paper, or fibrous material being placed 25 therein. I prefer to give eight turns of the wires round the mandril for each element of the band, and these are connected for any length by cords or threads laid in the edges of the mandril before the pressure of the tool is brought upon the wires to hold the cords in place. The channels for the absorbent material may be round, square, or rectangular, 30 to suit the material, which may be cut or made to the exact size to fill the channel, or of pieces built up such as would be the case if perforated cards were used, whether they had a film of sponge or fibrous material between them or not. In some cases the absorbent material could be put in with the gg edge cords, and then it would be held in place in a secure manner. The fastenings for the bands, belts, or garments, if such are required, consist of two plates stamped with raised flanges; one of them has a
