GALVANIC BATTERY.

SPEGIEICATION forming part of Letters Patent No. 229,122, dated. June 22, 1880,

Application filed June 27, 1879.

To all whom it may concern:

Be it known that I, MARoUs A. HARDY, of the city and county of Newport, and State of Rhode Island, have invented a new and useful Improvement in Portable Galvanic Batteries, which improvement is fully set forth in the following specification, reference being had to the accompanying drawings.

My invention consists in a novel construction of battery, whereby I provide for emptying all the cells of a, battery simultaneously, saving the time and labor consumed in handling each cell separately, and making the battery easy and safe to transport without spilling the fluid.

My invention also consists in novel features of construction whereby the cleaning of the battery is facilitated, and in a novel method of suspending the carbon or other plates of a battery.

In the accompanying drawings, Figure l is a sectional elevation; Fig. 2, a plan view of the same; and Fig. 3 represents a detail view, partly in section and upon a larger scale, showing the manner of securing the plates in place.

A is a tank or reservoir, which is closed airtight by cover B, being secured by screws 8 es. On the top of B, and forming part of the same, are two or more square cells, C G, which are connected with reservoir A underneath by tubes D D, which lead nearly to the bottom of the reservoir. By removing the screws 8 s the cover B may be freed from the tank or reservoir A and be removed to facilitate the cleaning of the tank or reservoir and removing the salts which may deposit therein.

On the bottom of A is placed a plate, E, on top of which are secured soft-rubber plugs r 1' central under each tube D, which close the same when the plate E is raised. F F are two rods secured to the plate E and to the diaphragms G G, which are secured to the top of cover B, as shown. H is a hole for filling or emptying the reservoir, which is closed by an ordinary plug or screw-cap. K is a stop-cock secured to the top of cover B, and L is a rubber tube attached to the same. M is a cover which closes the top of the cells 0 O, to the under side of which are secured zinc plates Z and carbon plates P. N is a glass tube secured to the outside of one of the cells 0, which in-- dicates the height of the fluid in the cells. Although the carbon and zinc plates 1?. and Z maybe secured in any way to the cover M, the method of suspending them here shown is preferable, as it permits of their ready removal. The cover M has upon its under side downwardly-extending lugs or projections. 00 and b designates pins, projecting from their faces and of a size to enter holes in the carbon or zinc plates. 0 designates blocks of india-rubber, which, after the plates are placed upon said pins, are forced inward between the lugs or projections to, and thereby hold the plates in place. The downward displacement of the plates is prevented by the pins I), while their lateral displacement is prevented by the blocks 0.

The operation is as follows: Fill the reservoir A with the fluid through hole H, then close the same and open the stop-cock K and force air into the reservoir, when the fluid will immediately rise in cells C 0 through the tubes 1) D. When the cells are nearly filled, which is indicated by the height of the fluid in glass tube N, the air-pressure in the reservoir acts on the diaphragms G G, thereby raising the plate E and pressing the soft-rub ber plugs r 1" against the ends of tubes D, thus cutting oft the connection between the fluid in each cell 0 and the remaining fluid in the reservoir A; then close the stop-cock, confining the air-pressure in the reservoir, and the battery is ready for use. On opening the stopcook again the air-pressure escapes, the plate E drops to the bottom of the reservoir A, and the fluid recedes to the same at once. The plate E may also be raised by mechanical means instead of automatically.

I claim as my invention- 1. The combination, with a battery-cell and a reservoir for liquid arranged below the same, of a pipe or pipes for aftbrdin g communication between said cell and reservoir, a plate arranged in said reservoir below the end or ends of the pipe or pipes, and diaphragins connected with said plate, whereby an increase of airpressure within the reservoir will act upon said diaphragms and raise the said plate soas to close the said pipe or pipes, substantially as specified.

2. The combination, in a battery, with a tank or reservoir, of a removable cover therefor, cells arranged above said cover and in com- Inunication with said tank or reservoirf'and means for closing or opening the communication between said tank or reservoir and cells, whereby facility is afforded for removing the cover and cells when it is desired to clean the tank or reservoir, substantially as specified.

3. The combination of the cover M, provided 10 with the downwardly-extending lugs or proprojections a, having upon their sides pins 1),
