Improvements in and relating- to Apparatus for Receiving: Payment and Administering- Electricity for Medical or other Purposes. I, William John Woodward, of Judson’s & Co. Limited, Ewer Street, Southwark Street, in the County of Surrey, Electrician, do hereby declare the nature of this invention to be as follows :— My invention relates to apparatus for automatically administering electricity, and 5 more especially to apparatus of that kind or class intended to administer medical electricity to the human frame. The main object of my invention is to provide an apparatus by means of which upon inserting a coin or coins of the proper value into the said apparatus a primary or secondary current of electricity can be applied to the human body, for medical 10 purposes, the regulation of the strength of said current being entirely under the control of the person operating the apparatus. My said invention comprises moreover various other improvements hereinafter set forth. In carrying my said invention into practice I provide an enclosing case or box 15 of suitable dimensions, the front and top thereof being preferably hinged for facilitating access to the interior. Within said case or box is arranged one or more cells of an electric battery, of any suitable type. Upon one side of the interior of the case or box is attached an induction coil, or in certain cases I may employ a primary coil, suspended upon a suitable pivot so 20 that it may be free to move laterally. Two handles of suitable size and form are attached to the exterior front of the said case or box, one of which is fixed, and the other arranged to allow of its being turned to the right or to the left as may be desired. A double crank, fitted upon the spindle of a movable handle within the case or box allows of the rotation thereof against the tension of a spiral or other 25 spring for the purpose of causing an iron coil, to slide in and out of the coil in order that the strength or intensity of the current of electricity may be regulated according to requirements. A contact cam is fixed upon the spindle of the movable handle, in such a manner that it makes electrical contact with a metal spring or brush upon a slight rotary 30 movement of the said movable handle and spindle and thereby completes the electrical circuit, the spring or brush being electrically connected to one pole of the battery above mentioned. The opposite pole of said battery is connected through a suitable contact breaker and coil to the movable handle. A metal catch is pivotted to the case, the lower end of this catch engages with a cam piece upon the spindle of said 35 movable handle. A flap attached to, or forming part of the said cam piece closes or partly closes the lower opening of a suitable trough or chute the position of the aperture corresponding with a slit in the lid of the containing case or box. A coin of predetermined weight, size and value, being inserted in said slit, will fall by gravity down the said trough or chute, and strike the pivoted balanced flap which becomes 40 displaced, and thns removes the catch from its engagement with the cam piece. The movable handle may now be turned and electrical contact is thus established between the contact breaker (which is connected to the battery) and the said movable handle. The secondary wires are also coupled to the two handles respectively, or, in the 45 case of a primary coil, the primary wires are suitably branched to serve the purpose of conveying the current to the handles. The movable handle is locked by the hereinbefore described catch and cam piece until a coin of sufficient weight to balance the said catch is dropped through the orifice or slit in the box or case^ and until this operation is performed the electrical contact is not established [ Prit4 8c?.]
