iM PiiovE'MEiNi" iN GALVAN i o` BA Speeiication forming'lpart of Letters Patent No. 6,862, dated April, 17, 1849.

To all 'whom it may coiwern:

Beit known that 1, ADoLPHUs tlLrrsrnnn, of the borough of Easton, in the countfyof Northampton and State of Pennsylvania, have invented a new und useful improvement in'the hydro galvnnic electro magnetic instrument for medici nahchcmical, philosophical, mechanical, and other purposes,` called Olnisteads Improved Voltaie Arrangement, which iede- Yscribed as follows, reference being had tothe annexed drawings of the saine, nia-king part of jthis speciiicnton.

Figure l is a perspective View of the apparatus as arranged for operation. `Side elevation of the shield, plates, studs, pins,- Fig. Il is one of the copper pins detached from its circle. Fig. 5 is one of the zine pins, also detached from its circle. Fie'. (3 is a plan or top View of the galvanic battery. Fig. 7 is' an inverted view of the saine.

Similar letters in the several figures refer to corresponding parts.,

rihe nature of my invention and improveuufut consists in forming a galvanic battery of concentric plates or rings U U', containing,r i-,opper' and zinc pins or plates, said rings U U being of similar or dissimilar metals7 arranged in. alternate order and united by.' wires Vr', This galranic battery is placed in a stutionnri;l cell, t), or reservoir, of glass oriother suits-b c material, and is connected to an electromagnetic battery, l1, by conductingarires l, in the usual way. The wheel H of the electro-magnetic battery is turned by mechanical ineens linstead oit' by hand.

.'Lhc mechanism I generally employ consists etang of the known powers ot' motion, such asa coiicd spring arranged in the box .or eylindrieal case K2, and cogged wheels L orweights, etc., driving atrain ot wheels coni-iected to a pinion, lll, on the shal't'N of thiir electro-magnetic wheel Il.

The galraniebatteryfor producing roltaic electricity for medical and other purposes is constructed of a series of perforated concentrie metallic rings, U U', connected together by coiilucting-wires YV, said rings being ai'.- tuoheti by screws or other means to a perlorated cover or shield of wood, Y, which is placed over the top ol' a gah-anic trough, t), containing;diluted sulphuric ncid, through which cover and rin are introduced coppe and zinc plates or pins, solid or tubular, forin; ingr a powerful battery, involving in its own formation a natural and perfect mode of graduation, giving at all times the' operator thel most entire control over the quantity of its ininence by the addition or subtraction of the aforesaid pins or plates. l

V 1s the shield; U Uf, the concentric rings screwed to the shield; il", the cond noting-wires; for connecting the brass rings, as represented in the drawings; T T', the coppernnd zine pins; l I, the conducting-wires for connecting fthe galvanie battery with the magnetic bat tort rlhe galranie battery nia-y also be formedl'of perforated metallic bars 'of similar or dissimilar metals, connected alternately by wires,,as above described, through which copper and rinoV plates or plus, solid or tubular, niej* be introduced to form the battery on tlie'sauie principle ns above stated, the pins or plates being increased in number to-strengthenand diminished to reduce the batter? Operation: Adjust the cover i rshield-ovcr the top of a gnlvan ie trough containingr diluted sulphurio acid or other veorroding liquid, the surface of the solution being` about half iin-inch from the underside ol' the perforated pia-tes attached to the shield, and the perforated plates being,` conn eted by conducting-wires to the magnetic battery, and the instrument otherwise properly adjusted, thel operator will introduce through the apertures in the rings or bars copper and zine pins or plates, forming a single roltnie pair in notion. ll' the nc -tion. be snliicient, the operator will proceed;

but it' too leeble another pair must be introduced, and so on until a suilicient action be obtained to produce the desir -d elle: 1i' found to act too powerful, it un st by withdrawing the pins or plates battery, which rires the operalor at all times complete control over the urti-on ci' the inslruf nient, and doesaway with the ordinary modes of graduating' the batteryV by raisin and low` ering the plates or elevating und depressing the acid solution in which the plates are inw iuersed. y

What l claim as .my invention, and desire to secure by .Leiters Primarias@ Tennis. y

' Uonstruot-ng the battery 'with perforated In testimony whereof I have hereuntosubrings or bars, through which are inserted tuscribed my neme before two subscribing witbular or solid pins or plates of zine and copper, messes, v or other suitable metals, in the manner and for the purpose herein set forth, for prodoing Witnesses: voltaie electricity for medicinal and other purvWM.
