STORAGE-BATTERY CELL.

Specification of Letters Patent.

Patented May 11, 1920.

Application filed June 3, 1918, Serial No. 238,028;

To all whom it may concern:

Be it known that I, JACOB C. EICHHORN, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Storage-Battery Cells, of which the following is a specification, reference being had therein to the accompanying drawings.

In the construction of cells or jars for storage batteries, it has been hitherto the custom, so far as known to me, to seal the top with wax or like material, owing to the diliiculty experienced in securing a cover of suitable form upon the top in such manner as to provide for ventilation and at the same time give ready access to the jar.

This invention relates to a battery jar and to means for closing or sealing the same which obviates the necessity of the use of wax or other like material, which perfectly vents the jar and maintains the vent in open condition at all times, while it gives access to the jar interior without the necessity of removing any cementitious material.

The invention consists in the matters hereinafter set forth, and more particularly pointed out in the appended claims.

In the drawings,

Figure 1 is a view in side elevation, partially broken away and in section, of a battery jar that embodies features of the inven tion;

Fig. 2 is a plan view of the jar with the terminals removed;

Fig. 3 is a plan View of the bottom of the jar cover;

Fig. 4 is a view in central cross sectio through the jar cover; and

Fig. 5 is a detail view of one means of clamping the lid in place.

As herein shown, a battery jar 1 of the usual rectangular form and dimensions desired, is provided around its margin with an outstanding flange 2, the jar being preferably of glass or like vitreous material. A cover of glass is disposed thereon. This has a depending internal flange 3 extending completely around it, proportioned to be just within the upright wall of the jar and to act, in fact as .a centering member therefor. An upwardly extending marginal clamping rib 4, the top of which may be rounded, likewise encircles the lid, the margin of which. conforms exteriorly with the outer edge portion of the flange 2. The

I cover isapertured at15 f0r the insertion of the usual terminals. The body of the cover within the flange is crowned or cambered outwardly as indicated at 5 so that it slopes gradually upward toward a centrally disposed, oval, depending baflie 6. Within the baille, there is a slightly depressed portion 7 through which a vent opening 8 is formed.

A gasket 9 of suitable material is interposed between the jar and the lid and the whole is securely clamped together by clips 10 which may be of any preferred type, but, as herein shown, each consists of a body 11 with a pair of inturned lugs 12 bearing upwardly against the underside of the flange 2 and a pair of hook ears 13 bent to snap over the clamping rib 4 and yieldingly force the parts together. For ease of removal, the end portions 14 of the bodyof the clip are outturned.

The jar that is thus obtained, is hermetically sealed in such a manner as to be readily accessible, and perfectly ventilated. In case of any splashing, the baffle of the crowned middle portion deflects .the liquid and prevents it entering the vent opening while at the same time if there is any direct splashing upward into the opening, the outer face of the cover permits the liquid to drain back into the jar. Because of the yielding clamps, the gasket is kept compressed and the joint between the jar and the lid is at all times hermetically sealed. The jar is readily opened by snapping off the clips and lifting the cover, when access is had to the interior without the necessity of removing the wax or other like sealing material usually used.

hat I claim is 1. In battery cell constructions and in combination, a ar body having an open top, a cover therefor having its middle portion crowned upwardly, said crowned portion having a depression on its upper face and a depending rib on its lower face surrounding the depressed portion, said depressed portion having a vent opening, and means for securing the cover in position, the location of said means preventing its interference with the free operation of the vent opening.

2. In battery cell constructions, and in combination, a jar body having an open top,

said open top extending generally in two dimensions differing as to length, a cover therefor having a depending centering rib conforming to the general ,dimensions of such open top and'having its middle portion crowned upwardly in general correspondence with the different length dimensions, said crowned portion having a depression on its upper face and a depending rib on its lower face surrounding the depending portion, said depressedportion being elongated in the directionof length of the greatest dimension and having a vent opening, and

10 means for securing the cover in position, the

location of said means preventing-its interference with the free operation of the vent opening.

In testimony whereof I a'HiX my signature in-the presence of two witnesses.
