Application led May 22, 1915. Serial No. 29,730.
To all whom t may concern:
Be it known that l, HARRY WEmA, a citizen of the United States, .residing at Highland Park, in the county of Middlesex, State of New Jersey, have invented certain new and usefullmprovements in Storl age-Battery Separators, of which the following is a full, clear, and exact description. This invention relates to separators for secondary batteries, and has for -anobject ondary batteries, as commonly constructed, comprise a thin perforated sheet of hard rubber, provided with longitudinal spacing ribs superimposed thereonn The thin sheet is ordinarily first partially vulcanized, then perforated, then cut to size, reinforced by the superposed ribs, which are united by i cement, and the whole article as built up,
finished by subjecting to a final or second vulcanization. The principal objections to sheets'made as above described, lies in the fact that the thin unprotected top and bottom edges breakwith avery slight exing.
-By this invention I provide a structure wherein the tendency to break at the edge is very much reduced, all more fully set forth in the following description and illustrated in' the accompanying drawings, in which:
Figure 1 isa plan view lof a separator made according to my invention;y Fig. 2 is a cross-sectional view of the same, taken on the line 2 2, Fig. 1; and Fig. 3 is an enlarged fragmentary sectional view taken on the line 3 3, Fig'l, showing the edge reinforcement of the same.
lin the drawings, 4 designates a thin hard rubber sheet having its long edges provided with parallel ribs 5 integrally and symrnetrically formed on both sides ofthe sheet. Between the ribs 5 and longitudinal of the sheet are additional ribs 6' of smaller dimension formed on one or both sides of.
the sheet il, and preferably uniformly separated..
rllhe structure thus far described provides means for maintaining proper separation without obstructing circulation in the battery or causing localized accumulation of sediment tending to short-circuitthe plates. To obviate longitudinal breaksfrom longitudinal flexing, I form at the short edges of the sheet 4 thickened portions 7 clearly shown in Fig. 3. rllhese thickened portions 7 are integrally formed in the mold when the sheet is shaped and are 'madeof less thickness than the longitudinal ribs 5 and 6. This lesser thickness is essential in order that there be no obstacle to the circulation or tendency to cause accumulation of sediment in the battery jar.
the bottom of the ar, thus eliminating the The thickened edges are preferably made tapering, as`
possibility of a short-circuit between the negative and positive plates.` The sheet as formed is finished by punching the perforations 8 in the thin portion of the sheet, the i thickened edges 7 being left unperforated.
By the above described construction, lf provide a separator which will withstand the flexing to which such articles are ordinarily subjected, without, however, interfering with circulation of'the electrolyte or the flow of current from one plate to the other in the battery jar. llnasmuch as the sheet and its reinforcements are integral, it
can be formed by molding in a single operation.
What l Letters Patent is:
A separator for battery plates comprising al perforated sheet` of non-conductive.
material, longitudinal spacing ribs on opclaim and desire to protect by yposite sides thereof, and unperforated thick- I ened margins diverging from .said sheet to reinforce the same without obstruction to the spaces at each side of thesheet.
