Improved Construction of Plates and Arrangement of Fastenings for Connecting tliem in Voltaic Order for Medico Electric Purposes. I William George Johnson of The Medico Electric Belt, Truss and Battery Company Limited, 58 New Bond Street, Middlesex Electrician do hereby declare the nature of my said invention to be as follows :— This invention relates to a certain novel construction of plates for making the 5 elements of Medico Electric bands also in means of connecting said elements in Voltaic order to any desired length according to the purposes for which said band is intended or the position it has to occupy upon the body. One plate of each element, say the copper, is formed with rectangular or other shaped openings in the surface or surfaces and with cut through indented portions to 10 form lugs or ears from either the faces or ends for articulating them to the opposite pole plate of the other element, or by lacings of cat-gut or cord, in which case the ears or lugs would form the means of attachment through spiral or other wires so that each element has a freedom of action to and fro, also a twisting about to allow any part of the band to adapt itself to any part of the body to which it may 15 be applied. The terminals may be of disc or other shape and the cords, if cords be used, secured in or run through stamped indents forming loops, ears or lugs between which the cord can be clamped to fix it in position. The plates with the rectangular or other shaped openings have enclosed within 20 their folded portions the opposite pole plates of the element, these being protected by wrapped or laced thread. Any method or appliance can be used for fixing the plates or bands to the body or limb of a person and the band may be partly enclosed in a fabric by means of which the electrical power generated may be concentrated to the exposed pole plates 25 which alone may touch the person. Dated this 14th day of March 1888. H. GARDNER, 166, Fleet Street, London, Agent for the said W. G. Johnson. [Price 8J.]
