    N° 2393 A.D. 1892 Date of Application, Sth Feb., 1892 Complete Specification Left, 4th Nov., 1S92—Accepted, 17th Dec., 1892 PROVISIONAL SPECIFICATION. Improved Method of and Appliances for using Electricity as a Medicinal Agent. I, William Grigg, of No. 33 Eastbourne Terrace, Hyde Park in the County of Middlesex Medical Electrician do hereby declare the nature of this invention to be as follows :— My invention consists firstly, in various appliances for conveying an electric 6 current for medicinal purposes to any part of a human or animal body, under various conditions, and, secondly, an electro magnetic generator and regulator, which may be used with the appliances before referred to, or these may be used in combination with any other form of: generator or source of electricity. In carrying my invention into effect, I may use plates, cups, discs or the like 10 wholly or partly of conducting material, and suitably connected to my electro¬ magnetic machine, or any other source of current, so that said current may be applied and caused to flow between any two or more points or parts of a living body. I may use a conductive flooring as one pole, the other being applied as may be most desirable for medicinal or hygienic purposes. Or I may use a plain 15 or medicated bath or baths as one or both poles, said bath or baths being suitably connected to and with the electro-magnetic or other generator. I may use bands or straps to permanently attach one or both poles to the body during treatment. The second part of my said invention consists of a tube, preferably made of some insulating material, upon which insulated copper wire is wound in successive 20 layers, each layer however being shorter than that preceding it. A magnetic core of laminated soft iron is arranged so as to be freely moved to and fro within the tube forming the base of the coil. The two ends of the coil are connected through a suitable magnetic contact-breaker with a battery or other source of electricity, the connections leading from the apparatus to the appliances for placing upon the 2!5 body, forming a shunt to the battery circuit. Regulation is effected by the insertion or withdrawal of the magnetic core, which is graduated to allow of delicate manipulation. In order to further ensure regulation, I may cause the end of each layer upon the coil to project for attachment to the contact bars of a switch for cutting any required number of layers out of the circuit. Also, instead 30 of using a shunt to the battery connections, as a means for coupling the various appliances used for making contact with a living body, with the apparatus, I may use one or more layers of wire wound over the conical coil before mentioned, and couple the two ends thereof directly to the appliances before mentioned, the afore¬ said conical coil and its regulator remaining intact, and the action thereof being 35 the same. The outer layer or layers of wire in this case may be of less sectional area, and consequently of greater electrical resistance than that receiving the direct or primary current, and therefore the current applied to the body is an induced current of higher potential. This, however, is only applicable in certain cases, and where adapted to the apparatus is so arranged that it may be cut out 40 and rendered inoperative, and the primary current used at will. My invention is intended for the cure and prevention of diseases in human beings and animals, the restoration and increase of vitality, elimination of deleterious matter from the system, and the reduction of abnormal growths, gradually and painlessly. 45 Dated this 4th day of February 1892.
