GALVANIC BATTERY.

SPECIFICATION forming part of Letters Patent No. 403,253, dated May 14, 1889.

Application filed October 1, 1888.v Serial No. 286,849. (No model.) Patented in Belgium .Tune 8, 1888, No. 82,112, and in England June 18, 1888l No. 8,905.

.To aZZ whom t may concern.-

Beit known that I, CHARLES COLLE, en-

gineer, (of the firm of Hector Lahousse da Co.,)

a citizen of the French Republic, and a resident of Lille, in the Republic of France, have invented certain new and useful Improvements in Electric Batteries, (for which I have obtained Letters Patent in Belgium, No.

82,112, dated June 8, 1888, and in Great Brit- 1o ain, No. 8,905, dated June 18, 1888,) of which the following is a specification.

This invention relates to an improved twoliquid battery, in which a novel liquid is employed to act on the zinc in the porous vessel I5 witha view of obtaining, by the aid of improved arrangements of the parts situated eX- ternally to the said porous vessel, a very constant current of great power at a relatively low cost.

And in order that my said invention may be fully understood, I shall now proceed more particularly to describe the same, and for that purpose shall refer to the several figures on the annexed sheets of drawings, the same let- 2 5 ters of reference indicating corresponding parts in all the figures.

Figure 1 of the accompanying drawings represents a battery according to this invention in vertical section. Fig. 2 is an end elevation Fig. 3 is a plan. Fig. 4t represents a perspective view of the top of the battery, showing the arrangement of the parts; and Fig. 5 represents an element with two carbons for a large battery.

The battery according to this invention is made with an external vessel of a material proof against the action of the concentrated nitric acid which it contains and inclosing a porous vessel, B, containing a special liquid 4o for acting on the Zinc, C. The space between the two vessels is filled with granular carbon, D, packed around electrodes E of retort-carbon, forming the positive pole, the whole being covered by a layer of pitch, H, or other suitable material, through which the porous vessel, the carbons, and two glass tubes, F F, project. The tube F is employed for introducin g the concentrated nitric acid, while the air escapes by the tube F. After this operation both the tubes are hermetically sealed, 5o to prevent any escape of hyponitric vapors.

The action on the zinc is obtained by means of a solution composed of about thirty-live parts, by weight, (say thirty-live grams,) of bisulphate of mercury and thirty-live parts, by weight, (thirty-five grams) of concentrated nitric acid in about one thousand part-s, by weight, (one liter,) of water. In preparing this solution the bisulphate must be mixed with three hundred parts (thirty centiliters) of water, in the first instance shaking or agitating it until the solution is of the color of yelk of eggs, and then continuing the agitation while the nitric acid is being poured in and until the liquid becomes clear. The solution thus prepared is poured into the porous vessel, in the interior of which the zinc is afterward placed, being allowed to rest upon a collar, G, of porcelain or other inoXidizable material, which also acts as a cover for the said porous vessel. The battery thus constituted is used in the same Way as an ordinary battery, over which it possesses the following advantages, namely:

First. The current is very regular and not liable to sudden accessions of force. The intensity of the current is about two volts and the quantity from about six and a half to seven ampres for a minimum period of action of about sixty hours.

Second. The zinc is equally acted on at all points, is consumed very slowly and with great regularity, and never requires taking out of the liquid.

Third. The residues are zinc salts and free mercury. These products are valuable, and may be collected either for the purpose of being regenerated or for sale.- In either case their commercial value is an important set off against the cost of working the battery.

Fourth. The battery requires but little attention to keep it in working order compared to a Leclanch battery, for example.

Fifth. Owing to the small proportion of the salt of mercury employed in one charge, and also owing to the long duration of each charge,

In a two-liquid battery with a porous cup, the combination of a solution of bisulphate of mercury and concentrated nitric acid in suitable proportions and a zinc plate in one cell, with granular-retort carbon and ordinary carbons and nitric acid in the other celhsubstantially as herein set forth.

In testimony that I claim the foregoing as my invention I have Signed lnynanle, in presence of two witnesses, this 18th day of September, 188%.
