Be it known that I, ALFRED C. GARRATT, of Boston, in Athe county of Suffolk, and Stete'of Massachusetts,/ha.ve inade a new and uSefnlInvention having Reference to Batteries ier `the Genceration of Electricity through the action of an acidon two diierent metals; and I :1o-hereby declare the same to'be fully described in the following specification, andrepresented in the accompanying drawings, of which- B igure lis s .n elevation of o ne of'my improved batteries "as open.

`Figure Sis a Section exhibiting the arrangement of its metall c bars and insulators.

Figure `Ll is a sideview oi' one of the cinc bars.

Figure 5 is a Vside View of one ofthe copper or yellow-metal ears of the series of bars in each oi' the fraines.

The battery improved by me is designed. chiefly for the convenience of medical practitioners in the production of electrical currents for curative or other purposes, 1t not, however, being limited thereto, as it often may v bQJiSeflllly employed in other` duties.

In some respects it may be said to contain one or more improvements with reference to the battery on which Letters Patent, No. 72,628, were granted to me en December 2li, A. D. 1867.

My present oriinproved battery is one of great durability andpower, of little expense, and simple in its construction, iseasily cleaned, and is-reezly fer-use with. little preparation-.er .delay,.an,d.w.hen Botn use infr-ee...

from destructive acids.. The ordinary combinationend arrangement of sheets or'disks of rnetals and cloths of the"voltaic pile is well'known. I therefore disclaim such.`

The nature of`my invention' consists principally in a new arrangement of the metallic bars and their insulaters; also, in the combination of two or more series of bars by hinging their frames together, and connecting thetwo series'by a chain or lexile connection, the same being so as to enablev the series, with its frames, to be foldednpon 'oneanother in a convenient manner for package und transportation.

Each bar of the scriesmy be rectangular, or itmay have any other suitable fornnin its transverse Section, Each series is composed of bars of zinc and copper, or yellow metal, arranged alternatelyjthesarne being as shown in the drawings, in whichda q denote the bars of zine, and b b b t-hose of cbpper or yellow metal.

' Each series is placed within the grooves of two grooved bars, ce, of-ai'raine, A., composed of two such bars, and metallic end connections d.

The two frames A A, I connect by hinges, arranged as shown at e e, in order thtione may be folded down upon the other, or both be unfolded, so as to he in one plane, and I connect, by means of a metallic chain, f, the

terminal zinc-bar of oneframe with the next adjaeent-terminal copper or yellow-metal bar of the other frame,

whichmay'bc accomplished .by means of small staples,g g,or their equivalents, connected with, inserted in, or

coniledngainst such terminal bers'.

Furthermore, instead of placing between each pair of zindand copper or zinc and yellow-'metal bars a. strip of cloth, I dispense'with such altogether, and simply arrange the two bers parallel and at a, Short distance asunder,

and place between them', at or near their ends, 'two small insulators or blocks, h k, of getta percha, glass, vulcanite. or equivalent insulating-material, leaving between these blocks and the next adjacent'side of the two barsva,'ar open space, i, the same being as shown in iig. 3. Y l

Each 'pair oi" the bars so arranged and insulated has a similar narrow. space, k, between. it and the next pair, the next adjacent bars of the two pairs being kept apart by tacks or metallic blocks placed between them,

er, what is better, by forming one of such bars withA small metallic projections Qrubutments ,'l Z, to extend from it in manner as shown in iig. 4. t

Furthermore, each metallic bar so provided with abutments is to be connected by solder to the bar which rests against such abutments, the solder being applied or arranged -a`t the ends of the two bars in manner as shown atjm m in the drawings.
