To @ZZ whom it may concern.-

2 Be it known that we, CHARLES R. B. OLAF- LIN, Jr., and J osEPH WA LTER FLAGG, citizens ofthe United States, residing at Worcester, in the county of Worcester and State of Massachusetts, haveinvented/a new and useful Improvement in Galvanic Batteries, of which the following is a specification, vcontaining av full, clear, and exact description, reference being had to the accompanying drawings, in which- Figure lrepresents a vertical sectional View of a battery embodying our invention; and Fig. 2 is a top viewwith the cover, excitingfluid, and depolarizing material omitted.

like parts in the several views.

,Ay A denote a metallic jar, preferably of iron, having inwardlyprojecting spurs or ledges B a short distance above the bottom of.

the jar to support the spider C, made preferably of iron or of the same material as the/jar` A A, which is formed of the three annular rings D D D, united bythe radialarms E. In each of the rings yDVD we cast the sheetiron cylinders F F,which are thus united to therings and are supported in a vertical p0- sition, or .instead of being cast in the rings they may be otherwise united Vso as to secure a close contact. Cylinders G, of sheetmetal, preferably of iron and finely perforated, are, placed over-the outer edgeof the ring D, the

' inner edge of ythe ring D2, and the outer and y jar.

inner k,edges offtheing D', with theiry lower edges resting on the radial arms E,whose uppersurfaces are slightly below the upper surfaces ofthe rings, as shownin Fig. 1. AThe solid cylinders F F and the perforated cylinders G thus form annular chambers H, which are closed at the bottom-'by the .rings D D', and an annular space is also formed by the vouter perforated cylinder and the sides of the In each of the annular spaces J between the perforated cylinders we place the cylin- -ders of zinc, J, supportedtby the insulating feet or stands K,which we make preferably of wood vor porcelain and which are shown yinl elevation in Fig. 1. These feet consist of a hase, a, and a conical top, a', having a groove toreceive the zinc cylinders J. A cylindrical cup or reservoir, L, closed at its lower end .and having perforations L in its sides, is s'usy per edge of the inner iron cylinder, F.

In charging the battery we till" the'annular' chambers, H'with a depolarizing material, H',

preferably ofgoxide of copper,.which forms a wall of oxide of copper held by the perforated ycylinders G in, contact with the solid iron cylinders F'F," and also with thefinn'er surface of thesides of the'janwhich form the negative electrodes of the battery, An excitinguid, kpreferably a Jsolutionvofkpo'tash, is then placed in the jar, nearly filling it, as shown reservoir L an'd a cover, M, is placed on the jar with its edges'resting on an'y elasticgasket pendeabythe hooksmwhit-h resto-nine up? of rubber or other suitable material, by which vthe jar is hermetieally sealed by, means ofthe hooks N,attached to the'projections N on the p' f- Y .70 Y' outside of the jar, and which are sprung over theedge of ythe cover, their elasticity servlng yto hold the cover in `close Vcontact with the elastic gasket.' Y .g y, v Insulating-stoppcrs P arefplacedlnholesin the cover, through, which wires P', connectedr which the circuit-wire Ps'is taken.

taken, which is thus connected through the Beneath each of the zinc cylinders J are annuf 8oV iron jarwith the ironor negative electrodes.v l f f larfopenngsJbroken only by the radial arms, j [f and in the center of the jar isa circular opening beneath ythe reservoir L, by which the cen-l tral space inclosed by the iron cylinder F and,

the annular spaces J J havea communication. Y withthe chamber Q between thebott'omof the',v v A jar and the spider C. The action of the battery is the same as the Well-known potash and oxide-of-copper battery, and does not require particular description.

struction. The negative electrodes. are carried both sides of the zinc cylinders and atpequal In our improved batf vtery, however, we ylargely increasenits',forcev y, ,1. and prolong its efficiency by our peculiar con-v upon height. The depolarizing material is confined by the perforated walls, which 'allow-theme11-y Aciting-fluid to enter freely andcome in contact with the negativeelectrodes.

The solution forming the excitingfliiid'is maintained by the immersed crystals held in the reservoir L, and the deposit arisingfroml crystalllzation or other causes is permitted to the zinc cylinders are conical in form, in or-rf der to allow the deposit to slide off and prevent its accumulation in contact with the zinc cylinders.

The number of zinc cylinders may be diminlshed or increased, as desired, or the central reservoir may be omitted in the form, as shown, and a bottom placed in the central cylinder, F, forming a reservoir for crystals of potash, or they may be suspended in the exciting-fluid in any ofthe well-known methods.

We are aware that the electrodes of a gal vanlc battery have heretofore woundinto volutes and embedded in an excitant material. Such we do not claim.

What we claim as our invention, and desire to secure by Letters Patent, is

1. In a galvanic battery consisting of a jar containing an exciting-fluid, a positive electrode formed ot' a Wall standing vertically in said exciting-fluid, a negative electrode formed of a vertical wall presenting 'an opposing face to the positive electrode, a perforated wall parallel with the surface of the negative electrode, and a depolarizing material held between the negative electrode and said perforated wall, substantially as described, and for the purpose set forth.

2. In a galvanic battery, the combination, with a jar containing an exciting-fluid, of a spider or disk having openings and supporting the positive and negative electrodes, said spider or disk being maintained in position in said jar above the bottom, so as to form a chamber for the deposit of solid matter, substantially as described.

3. In a galvanic battery, the combination, with a jar containing an exciting-fluid and a central reservoir containing the crystals of the exciting-salt, of a series of positive and negative electrodes placed alternately around said central reservoir,with annular spaces between said electrodes for the exciting-fluid, said annular spaces communicating with each other, substantially as described, and for the purpose set forth.

4. In a galvanic battery, the combination, with a jar containing an exciting-Huid and positive and negative electrodes, of supporting-feet by which said positive electrodes are held above the bottom of the jar, the upper surface of said feet being conical, as and for the purpose, set forth.

5. In a galvanic battery, the combination, with a jar containing an exciting-fluid and positive and negative electrodes, of a cover f1tting said jar, an elastic gasket between said jar and cover, and elastic hooks attached to said jar and engaging the upper surface of the cover, substantially as described.

6. In a galvanic battery, the combination, with a jar containing an exciting-duid and positive and negative electrodes, of a central chamber communicating with the spaces around the positive and negative poles, and a reservoir suspended in said central chamber, substantially as described, and for the purpose set forth.

7. In a galvanic battery, the combination, with a jar containing an exciting-fluid, of the positive electrodes J negative electrodes F F', perforated walls G,and depolarizing material, H, said electrodes, perforated walls, and de-4 polarizing material being arranged in vertical walls immersed in the exciting-fluid, substantially as described.

8. In a galvanic battery, the combination, with a jar containing an exciting-fluid and positive and negative electrodes, of spurs B, spider C, having openings J2, said spider supporting the electrodes above the bottom of the jar, and a central reservoir containing the crystals of the exciting-salt, substantially as described.
