STORAGE-BATTERY JAR.

Specification of Letters Patent.

Patented Mar. 11%, 1918.

Application filed August 1, 1917. serial No. 183,914.

To all whom it may concern."

Be it known that I, EARL T. SCHMUCKER, a citizen of the United States, residing at Rapid City, in the county of Pennington and State of South Dakota, have invented new and useful Improvements in Storage-Battery Jars, of which the following is a specification.

This invention relates to improvements in battery jars having particular reference to a jar such as used for storage batteries or Objects of the invention are to furnish a battery jar which will be proof against leakage as a result of rough handling and which has an improved arrangement of the parts whereby the removal of the sediment accumulating in such jars is facilitated.

Other objects will appear from the following description taken in connection with the claim and the drawings.

In the drawings:

Figure 1 represents a vertical section through the jar showing one of the plates of the battery positioned therein.

Fig. 2 represents a vertical section taken on the line 22 of Fig. 1.

In the drawings, the numeral 1 represents the jar as a whole, which has an inner vessel 2 for containing the plates 3 of the battery and the electrolyte, said vessel preferably constructed of a rigid insulating non-corrosive material, such as hard rubber, commonly used for storage battery jars. In the present instance the inner vessel 2 is formed with a,slanting bottom 4 and with ribs 5 extending transversely thereof, and preferably constituting integral portions of the sides. The ribs 5 are adapted for maintaining in position the plates 3 of the battery and the slanting bottom 4 isdesigned to permit gravitational movement of the sediment dropping'ofl the plates 3 toward the lower portion of the vessel 2 which constitutes a sediment pocket 6 from which the sediment may be removed with a battery syringe or other convenient means. To permit such movement the ribs 5 are spaced above the bottom to have openings 7. Surrounding and closely fitting the vessel 2 is a jar 8 having the form of a jacket of flexible noncorrosive insulating material; and preferably, of flexible rubber. It will be seen that the flexible rubber jacket is maintained in proper shape by the inner vessel 2 and in the event of damage to the inner vessel will prevent leakage of the contents; and is further adapted to protect the inner vessel 2 from shocks whereby it might be fractured. The flexible rubber jacket 8 is further retained in shape by. a rigid outer vessel or casing 9 which is preferably of the same material as the inner vessel 2, and shaped in ternally to conform with the exterior of the vessel although sufficiently larger to permit the insertion between them of the jacket. At the higher end of its sloping bottom and along both sides, this casing has a depending flange 10, which may be strengthened by a leg 11, and constitutes a continuation of the sides whereby the casing 9 is adapted for securely maintaining a position upon a flat surface.

It will be evident that the invention is not necessarily limited to the particular form shown and described and I reserve the right to such variations, modification and alterations of the component parts and arrangement thereof as may fall within the spirit of the invention and scope of the claim.

What I claim is:-

In a battery jar, the combination with an inner vessel of insulating material having its bottom sloping toward one side, and means therein for supporting the batteryplates in horizontal position; of an outer vessel conforming in shape with the sides and bottom ofTjsa'id inner vessel and having a depending flange at the higher edge of its raised bottom for holding its sides upright, and a leg depending from said bottom between its higher and lower edges.

EARL r. SCHMUCKER.
