    2 A.D. 1885.—N° 10,606. Complete Specification. Kennedy s Improvements in Curative Voltaic Batteries. and said disc or shell C thus united constitute the enclosing cup of my battery. Pivoted to face of annulus A are buttons Z of zinc. 1. 2. 3 are three voltaic couples or systems of which each system comprises three discs z. d. c} of zinc, cloth and copper respectively of size adapted to loosely occupy the central orifice of my cup A. C Of these discs all the metal ones except the 5 bottom one are preferably perforated at their centres as shown in Fig. 5 for the free passage of the acidulated water or other excitant. In the form of my^ invention here selected for illustration, the unperforated zinc disc shown at the extreme left of Fig. 5. is first inserted, then a diaphragm of moistened cloth, followed by a copper disc, these three pieces composing one system or couple, after 10 which the other couples are inserted in like order and are secured by the closure over them of the buttons Z. The apparatus is now ready for use. Should the galvanic action become impaired by the drying up or the neutralization of the acid, it cau be restored at any moment by pouring in additional acid through the central orifices or by 15 taking the discs out and re-moistening the diaphragms. Whichever of these modes be adopted, care must be taken that while applying sufficient acid for saturation of the diaphragms such excess is avoided as would moisten the contiguous metallic surfaces of the consecutive couples, and thus generate counter-currents. Whenever the metallic surfaces have become too much 20 impaired by oxidization, the battery is taken apart, and the surfaces cleaned. At the same time the diaphragms may be renewed if necessary. If the galvanic action is found to be too strong it may be moderated by turning one or more of the buttons Z out of contact with the last copper disc c as indicated by dotted lines in Fig. 1. The above described embodiment of my invention is manifestly 25 susceptible of various modifications. For example, the plate C may be made a member of the first couple by the interposition of a diaphragm between it and the first zinc disc, which in that case may be perforated like the others. Such arrangement would be represented by substituting the plate C for the right hand copper disc c in Fig. 5. and counting the systems from right to left so as to 30 finish with the left hand zinc disc. In such arrangement the buttons may be of copper or any other electrical conductor. Carbon, silver or platinum may be used instead of the copper. Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed I declare that what 35 I claim is A voltaic battery adapted to be worn on the person consisting of a non¬ conducting annulus A and metallic shell C c1 constituting a cup or receptacle, within which one or more voltaic “ couples ” are enclosed by means of buttons Z substantially as set forth. 4Q Dated this eighth day of September 1885.
