    Hunt's Improved Physiological or “ Button ” Battery. Battery ” (a communication to me from abroad by Alfred Charles Garratt, of Boston, Massachusetts, United States of America), upon the condition (amongst others) that I, the said Bristow Hunt, my executors or administrators, by an instrument in writing under my, or their, or 5 one of their hands and seals, should particularly describe and ascertain the nature of the said Invention, and in what manner the same was to be performed, and cause the same to be filed in the Great Seal Patent Office within six calendar months next and immediately after the date of the said Letters Patent. 10 NOW KNOW YE, that I, the said Bristow Hunt, do hereby declare the nature of the said Invention, and in what manner the same is to be performed, to be particularly described and ascertained in and by the following statement in writing, and on reference being had to the accompanying Drawing, that is to say:— 15 This Invention relates to an improved physiological or button ” battery, and has for its objects the attainment of greater elasticity, and the production of a simple “ one element battery ” as a whole ; the result of the improved construction being that the equivalent of a copper and zinc pair of plates is utilized. 20 The improved battery is illustrated on the accompanying Drawings in Figures 1 and 2, being a front and a back view respectively. The Invention consists in adjusting buttons or discs of copper or silver and of zinc or alloy (or their equivalents in dissimilar metals) upon a flexible insulation as a base, with metallic connections upon the back, 25 the whole being arranged and constructed so that the battery is made pliable, durable, and capable of being worn upon any uneven surface of the body or limbs. a represents zinc or zinc and magnesium, and c copper or silver buttons or discs which are attached to a flexible base A by means 30 of metal eyes rivetted or soldered into metal plates b} see Figure 2, and connected upon the back of the battery by copper wires d in all directions, such as crosswise, diagonally, and lengthwise, making the metallic connections between the buttons perfectly sure. Or the buttons may be connected in pairs thus, a\ a2> &3, with c1, c2, c3, or with c3, c3, c\ 35 so that if one or more wires break the action is still uninterrupted. Between the flexible back B and the front rubber or other suitable material C is applied for protection against outside influences. The
