B. FCJRI) STORAGE BATTERY CELL COVER Filed June 50, 1925 ATTORNEY I Patented Apr. 20, 1926.
UNITED STATES BRUCE FORD, 013 PHILADELPHIA, PENNSYLVANIA.
STORAGE-BATTERY-CELL COVER.
Application filed June 30, 1925. Serial No. 40,491.
' To all whom it may} conoem:
. Be it knownthat I, BRUCE Form, a citizen of the United States, residing at Philadelphia, in the coimty' of Philadelphia and 3 State of Pennsylvania, have invented certain new and useful Improvements in Storage-Battery-Cell Covers, of which the following is a specification.
The principal object of the present invention is to provide in the construction ofcell covers of hard rubber or hard rubber material for permitting a cover that would be too large for a jar to be pushed into the jar and make such a good fit as is required or, in other words, to provide in the construction of a cell cover of hard rubber or rubber material for such contraction as is necessary for insuring the required fit in the jar without a the necessity for grinding the cover which 20 has heretofore been the practice and which is expensive and whichis often overdone permitting sealing compound to run into the cell or ar.
(lther objects of the invention will appear from the following description which will be made in connection with the accompanying drawing and at the end of which the invention will be claimed.
Referring to the drawing Figure 1 is a view partly in section and partly in elevation illustrating one embodiment of the invention and showing parts of a stprage battery. Fig. 2 is a plan view of a cover embodymg a modification, and
Fig. 3 is a plan view of a part of a cover embodying another modification. In the drawing 1 is a cell cover of hard rubber or rubber material concave as at 2 $40 and having a depending inwardly offset external marginal wall or skirt 3 provided with an outwardly extending marginal flange 4 to provide space for sealing compound 5 between it and the inner face .of the wall of the jar A. It may be remarked that the cover is generally rectangular and is supported and positioned by the plate structare B, and that the ofifset of the marginal wall or skirt provides space for sealing compound 5, and that the marginal flange is the means for preventing the sealing compound 5, when fluid, from entering the interior of the cell or jar, therefore there should be a goodfit at the rim of the flange 4 with the interior surface ofthe jar B. By my invention this necessary fit is provided by sliterably inclined at an angle to permit of min-. 55 i imum width in respect to amount of takeup, The slits may be provided by the use of appropriate cores in the mold in which the cover is made. The slits may be variously disposed and positioned and there should preferably be at least one slit for each of the four portions of the marginal wall of the cover. As shown in Fig. 1 the slits 6 are located about midway of the length of the wall through which they are provided, and they are inclined in the direction of the thickness of the cover. As shown in Fig. 2
the slits 6 are inclined crosswise in the di rection of the plane of the cover. As shown in Fig. 3 there are two slits 6 for each side and two slits for each end of the cover and they are arranged in pairs at the four corners, inclined at an angle to the sides and ends of the cover.
In use the slits impart to the cover the ability to contract and enter a jar which would otherwise be too small to receive the cover and in this way proper fit for retaming the sealing compound is provided inexpensively and satisfactorily and without resort to grinding.
It will be obviously to those skilled in the art to which the invention relates that modi fications may be made in details of construcr tion and arrangement and matters of mere form without departing from the spirit of wall provided with a marginal flan e having two slits for each side and two s its for each end, said slits arranged in pairs at the four corners.
3. A storage battery cover consisting of a body portion having a depending wall provided with a marginal flange shts through said flange disposed in angular relation to the sides and ends to provlde a take-up in fittin BRUCE FORD.
