GALVANIC BATTERY.

SPECIFICATION forming part of Letters Patent No. 374,631, dated December 13,1887.

Application filed Sept mber 12, 1887. Serial No. 249,450. (No model.)

To aZZ whom it may concern.-

Be it known that I, J AMES SERsoN,of Boston, in the county of Suffolk, State of Massachusetts, have invented certain new and useful Improvements in Galvanic Batteries, of which the following is a description sufficiently full, clear,

and exact to enable any person skilled in the art or science to which said invention appertains to make and use the same, reference being had to the accompanying drawings, forming part of this'specification', in which- Figure 1 is a top plan'view of my improved galvanic battery, and Fig. 2 a vertical section taken on the dotted line as a; in Fig. 1.

Like letters of reference indicate corresponding parts'in both figures of the drawings.

My invention relates to that class of galvanic batteries which are provided with re-enforcing or feeding cups; and it consists in a novel construction and arrangement of parts, ashereinafter more fully set forth and claimed,the object being to produce a simpler, cheaper, and more effective device of this character than is now in ordinary use.

The nature and operation of the i mprovement will be readily understood by all conversant with such matters from the following explanation.

1n the drawings, A represents the outer or containingjar, and B the porous or innerjar. The outer jar is made of glass or similar material and provided with a cover, 0, which may be secured to the body of the jar and made air and water tight in any convenient and suitable manner. The inner jar is preferably composed of biscuit porcelain or analogous porous materials, and is provided with legsm, on which it is supported within the jar A. A feeding or re-enforcing cup, D, is formed integral with the body of the porous jar B, said cup being arranged vertically at one side of said jar and crescentshaped in horizontal section, as shown by dotted lines in Fig, 1.

Projecting from the outer side of the porous 45 jar B, near its bottom, there is a shelf, f, provided with an upwardly-projecting flange, 2, at its outer edge, said shelf and flange constituting a gutter, which, for convenience of reference,is marked E. This gutter extends from 50 one side of the cup D entirely around the base six parts of water.

solution, K, in the jar A. The walls of the of the jar B to the opposite side of the cup D, as shown in Fig. 1, and is partially filled with free mercury, t. A zinc plate, F, is inserted in the jar A, its lower edge resting in the gutter E.

The plate is cylindrical in form and is provided with a vertical opening or slot in one of its sides, through which the solution, K, flows, T and also for the reception of the cup D, as shown at E in Fig. 1. A stud, b, projects from the upper edge of said plate through a hole, d, in the cover 0, and to this stud is secured a screw-cap, g, for the conducting-wire i.

A carbon plate, H, provided at its upper end with a stud, c, which projects through a hole, r, in the cover 0, is disposed in the porous jar B, said stud being provided with a screwcap, h, for the conducting-wire k. .The porous cup B is filled around the plate H with granulated carbon and manganese, J. Thejar A is 7: filled with an acid ulated soluti0n,K,composed, preferably, of one part of sulphuric acid and The cup D is. filled wit-h sulphuric acid,N, forfeeding or re-enforcing the porous jar B are perforated, as shown at j, thereby permitting the solution, K, to freely enter said jar and act upon the plate H, and also upon the carbon and manganese, J. The walls of the cup, D, being porous, the acid, N, percolates the same in sufficient quantities to feed or re-enforce the solution, K. The free mercury, 25, in the channel E serves to keep the zinc plate F properly amalgamated, and thereby prevents its undue destruction by the action of the acidulated solution, K.

The action of a battery constructed as described is somewhat phenomenal; but I have found that its electro-motive force is greater than any with which I am acquainted and the danger of polarization less. The battery is also exceedingly simple, cheap, and durable.

Having thus explained my invention, what I claim is 1. In a galvanic battery of the character described, the perforated porous jar B, provided with the feeding-cup D and gutter E, constructed and arranged substantially as shown. 1

2. In a galvanic battery of the character 10c described, the jar A, provided with the cover 0, in combination with the porous jar B, provided with the cup' D and gutter E, substantially as Specified.

3. In a galvanic battery of the character described,the-perforated porous j ar B, pro vided 4. In a galvanic battery of the character described, a perforated porous jar provided with a gutter for containing free mercury and with a cup for containing a re-enforcing acid,

said cup and gutter being formed integral with :0

the body of the jar and the gutter and cup disposed on the outer side of said body, the cup being interposed between the ends of said gutter, substantially as shown and described.
