STORAGE BATTERY.

.Application led August 31, 1928. Serial No. 660,268.

This invention relates to improvements in storage batteries, the main object being to provide a strong and simple substitute for the) series of rubber cells and the protective wooden box ordinarily used to enclose the cells. Instead of using these several elements, the device lhereafter described comprises a single casting, preferably made of lead or an alloy, or other suitable substance that can be molded to produce the plurality of cells, the container made in this manner being strong enough towithstand the service shocks in an automobile, without being enclosed in another receptacle. In addition l5 to utilizing a single body o f metal for thev several containers of a storage battery, the invention preferably comprises handles formed integral with` the single body of metal, and ribs whereby the metal is reinforced below the handles. With the foregoing andother objects `fin view, the invention comprises the novel construction, combination 'and arrangement of parts hereinafter more specifically described and illustrated in the accompanying drawings wherein is shown the referred embodiment of the invention. owever, it is to be understood that the invention comprehends changes, variations and modifications which come within the j scope of the claims hereunto appended. Fig. I isa longitudinal section of a storage battery vcontainer embodying the features of this invention.

II is a transverse section of 7the container.

The container comprises a bottom wall 1, side walls 2, end walls 3 and artitions 4 arallel with the end walls, all of) these parts 40 eing integrally connected together. A; plurality of cells are thus formed by a single body of metal.l Y Ribs 5 extend upwardly from the bottom of the cells to support thepositive and nega-l tive plates inthe usual manner. These ribs are fparallel with the side walls, and they are pre erably integralwith the container.

Handles 6 lie above the end walls, each handle having downwardly 'extending ortions 7 vat its ends integrally connecte at the upper edgeof the end wall. A Each end wall is provided with a horizontal reinforcing rib 8 at its upper margin and reinforcing ribs 9 converging downwardly from the ends of said horizontal rib, all of said ribsbeing on the outer face of the end. wall at points directly below the handle, and the three ribs may be in the form of a triangle extending from the top to the bottom of the end wall. The handles are thus very ef'- fectively reinforced by ribs formed integral with the end walls.

g All of the elements previously described are preferably made of metal, and the several parts are formed by Ia single cast-ing, providing a strong, simple, durable and most electivejsubstitute for the numerous separate elements which are ordinarily assembled to produce the containers and handles of a storage battery.

-To economize in themanufacture and at 'the same time obtain the desired strength,

- As a further safeguard, to prevent the transmission of electrical energy through the walls of the metal container, the outer faces,

`of said container are likewise coated with an insulating acid-resisting substance 10. The

substance 10-10 may be a rubber composition or an asphaltic composition adapted to withstand the action of the acid in the battery, and also adapted to serve as an insu'- lator to prevent the transmission of an'electric current through the walls of the container. This substance, while in a liquid state, can be conveniently applied by dipping the container into the same.

I claim:

1. A storage battery container made of metal and having a partition formed integral therewith to provide a pluralityof cells within said container, an insulating acid-resisting substance applied to the entire in terior surface of said container, including said` partition, as a liner therefor, handles located at opposite ends of the container and formed integrally with the walls thereof, and

reinforcing ribs extending heightwise and widthwise of the walls to distribute throu hout the entire area of the wall tension t at is imparted thereto in lifting the container by means of said handles.

ranged in. the form of a triangle having one of its sides located adjacent to the handle formed integrally with the wall and an apex of the triangle located at the bottom of said wall substantially midway of the width thereof, and an insulating acid-resisting substance applied to the interior surface of said container, including said partition, as a liner therefor.

In testimony that I claim the foregoing I hereunto affix my signature.
