BATTERY.

SPECIFICATION forming part of Letters Patent No. 637,422, dated November 21, 1899.

Y Application filed March 2, 1899. *Serial No. 707,502. (No model.)

To all whom t may concern:

Be it known that I, CHARLES B. SCHOEN- MEHL, a citizen of the United States, and a resident of Waterbury, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Galvanic Batteries, of which the'followin'g is a specification.

The present invention relates to galvanic' batteries, and more particularly to the construction of a negative element therefor which includes a cover of novel construction.

It is the object of my invention to particularly improve upon the construction of batteries shown in my former patent, dated October 12, 1897, and numbered 591,427. In this connection I particularly improve upon the construction of the top and bottom of the basket forming the' negative element of said battery by producing therein means for retaining the negative-supportsin position,and,. further, to permit quicker assemblage of the parts, as will readily be understood from the detail description next to follow. v

With the above objects in View my invention resides and consists in the novel construction and combination of parts shown in the accompanying drawings, forming a part of this specication, and upon which similar letters of 'reference denote like or corresponding parts throughout the several figures, and of which- Figure l shows a central vertical cross-section of my improved battery-pole, together with a similar View of a common form of zincv element used in connection therewith. Fig. 2 is a sectional plan view showing the means for supporting the porcelain upon whichl the zinc rests. Fig. 3 shows a detail perspective view of the lowerportion of the basket, illustrating the pockets to receive said porcelainsupport. Fig. 4 is a perspective view of one of said porcelain-supports detached. Y

It will be obvious to those skilled in the art that it is not only desirable in the production of articles of manufacture to have them simple in construction, but it is also a great saving of time and money to construct them in such a manner as to permit of quick assemblage of the parts. Both of the above features have been foremost in my mind in the production of my present battery, as will be observed from the following detail description.

Referring to the letters of reference marked upon the drawings, A indicates a basket, which in practice is filled with the usual depolarizing agent of any preferred kind. The side walls of this basket are corrugated similar in all respects to that of my former pat- 6o ent, whereby agreater operative surface is afforded, andl consequently the strength of Athe battery enhanced. This basket is provided with detachable top and bottom B and C,respectively,which partsare secured thereto by means of rods D D, running vertically through the basket, as shown. The tops and ,bottoms are each provided with an inwardlyextended flange E, which in practice engages the outermost surface of the corrugations of 7o consequently afford a particular and desirable method for holding said blocks, since the time consumed in attaching the same is inconsiderable. The blocks H, of which there may be any desired number, are each provided with an outwardly-extended ledge I, upon which rests the cylindrical Zinc element J, which latter is provided with the usual form of wire connection K, as will be apparent.

The top B of the basket is similar in all re- 9o spects to the bottom except that 'it is provided with a central opening L, through which the basket may be charged or recharged. This opening, as will be apparent, is sufficientlyclosed by the cover M, which latter serves to inclose the jar. (Not shown.) As will be seen, the rods D, together with the nuts N, serve not only to retain the top and bottom of the basket in position, but also serve to. unite therewith the cover M, above referred roo to. Between these covers are preferably inserted insulating-washers O, and above the top cover and between it and the nut N is also inserted a second washer, thus securely insulating the rods, which may serve as a binding-post upon the cover and preventing the short-circniting of the battery should the covers touch when they are connected in a series.

By reason of the two covers connected as Shown the basket may be recharged without removing the inner cover, which is particularly desirable, since it is less trouble and expense.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

l. In a battery of the class described, the combination with a basket, of pockets formed against said basket and having walls upon all sides, insulating supporting-blocks retained in said pockets, and apositive element supported on said blocks, substantially as described. i

2. The combination in a negative electrode for batteries, of a basket containing a series of pockets upon its sides to receive and support insulating-blocks and two separate superposed detachable covers for said basket, the innermost one of which has a central opening therein.

3. rlhc combination in a battery-electrode of the class described, of a perforated corrugated cylindrical body, a top and bottom for said body and cach having inwardly-turned Hanges E forming pockets between said flanges and said corrugations.

4. The combination in a battery-electrode of the class described, of a corrugated cylindrical body, a top and bottom for said body having inwardlyturned anges E forming pockets between said Iianges and corrugations, and insulating-supports retained by said pockets, substantially as shown and described.

5. In a battery of the class described, the combination with a basket, of a detachable cover having an opening therethrough, a secondary cover over said opening and adapted to inclose the battery-jar, and suitable insulations between said covers.

6. In a battery of the class described, the combination of a corrugated basket, a detachable top and bottom therefor having inwardly-turned Hanges as shown, a secondary cover for said basket and the battery-jar, means for retaining said parts together, and suitable insulations between the covers aforesaid.

Signed at XVaterbury, in the county of New Haven and State of Connecticut, this 25th day of February, A. D. 1899.

CHARLES B. SCHOENMEHL.
