Improvements in Electric Apparatus for Therapeutic use. I Frederick Courtenay Fisher, of 64 Hampton Park, Redland, Bristol, Gentleman do hereby declare the nature of this invention to be as follows. — This invention consists of an apparatus for therapeutic purposes to be placed on the various parts of the body whereby an electro magnetic, a faradic or electro magnetic faradic current may be supplied. It consists of one or more electro magnets with or without secondary coil or coils which may be used with or without conductor or conductors and an interruptor when necessary, and is so arranged that it can be applied or worn on the body and connected to a battery or batteries or other generator of electricity, using sometimes primary and some- 10 times primary and secondary currents combined. The generator of electricity which it is preferred to use consists of three dry cells which can be placed on the table or carried in a pocket or worn in a wallet attached to the person. The belt is constructed on suitable material varying in width and length with 15 elastic belting securely fixed to one half of the belt, the other half of the belt sliding on the elastic belting to adjust position of electrodes and magnets, an adjustable clasp being provided upon the elastic belting to suit the size of person. A suitable snap button is used to attach the primary wire to cells from thence through contact breaker to bobbin and wound with several turns round a bundle 20 of wires or laminated stamped plates wrapped with insulation from thence to further sets of bundles of wires or stamped plates where more than one is used, thence to the other pole of the battery. The wires between the windings being made up with flexible wire to prevent breaking' or binding. The secondary wire after winding over the primary wire has one end carried over to a stud on the resistance switch and terminates at the electrode. The other end is wound on the next winding of primary and so on, to as many pri¬ maries as are used and ending finally in an electrode. The electrodes are connected to each other communicating with the secondarv wire and are placed on the opposite side of the belt to the windings and magnets. The belts may be made up as before described but without secondary wire and they may be made up without contact breaker and electrodes being merely a primary, or laminated wire or plates. A pad may be made up in the same way as described for the belt with the only difference that the shape is more of a rectangle and carries two loose elec- 35 trodes, wires of secondary being free and of suitable length to apply to any part of the body without necessarily attaching the pad to the body. The electrodes may be applied either by holding or strapping to the person while metallic cloth maybe used as electrodes. t _ For making and breaking the circuit of electricity the contact breaker may' 40 be made up of a fork magnet of laminated iron or bundles of iron wire insu- \~Price 8<L] 25 30
