ELMER A. SPERRY, or CLEVELAND, OHIO.
ELEMENT FOR STORAGE BATTERIES.
SPECIFICATION forming part of Letters Patent N 0. 649,998, dated May 22, 1900. Application filed September 30, 1899. Serial lilo. 732,147. (No model) To all whom it may concern:
Be it known that I, ELMER A. SPERRY, a citizen of the United States,"residin'g at Cleveland, in the county of Ouyahoga and State of Ohio, have invented certain new and useful Improvements in Elements for Storage Batteries, of which the following is a specification.
This invention relates to elements for storage batteries; and it consists in a novel arrangement and construction of a grid or supporting-plate for'the element constructed of suitable material-such, for instance, as lead or rich lead alloy. This grid or plate is illustrated in the accompanying drawings, in which- Figure 1 is a side elevation. Fig. 2 is a diagram of the cut portions of the perforations. Figs. 3 and 4 show the perforations with the lips turned in two stages of their development. Fig. 5 shows a section of the completed plate.
I have found that for the longest life with the least weight of cell, and especially for plates handling large currents, the plate should be more or less corrugated and at the same time should have certain strengtheningribs at the edges and through the plate, espe-T and also to strengthen the plate, and I havev found it preferable to drop from this top raised portion an additional rib B", extending into the body of the plate from the under side of theupper horizontal rim or edge A. The plate may be corrugated at any angle or vertically; but I prefer a horizontal corrugation, and when perforated I prefer to punch the holes H in the bottom or concave side of the perforations, allowing the lip or lips h resulting from the perforation to protrude from the convex side 4; of the corrugations in rows. These perforations I prefer to make polygonal, each alternate side of the polygon being cut, as shown at i 2', and bent, as shown at h h, the bent portions forming the extended lips being plainly seen in Figs. 1, 3, 4., and 5 after being punched. At first these lips across its nearest diagonal corners on line j,
as is plainly seen in Fig. 2. The lips stand off in parallel rows from alternate sides of the 'web, standing out parallel at first, as seen in Fig. 3, afterward being forced apart by the stylus S or otherwise, so. that they stand inclined away from each other and covering the convex portion or depression D of the adjacent corrugation. Thus it will be seen when the active material M is applied to the plates it occupies the depressions and is held, grasped, or riveted in place by the ends of the prongs h h, which are turned over upon the masses. The riveting action thus takes place on the thickest mass, lying, as it does,
in the trough or depressed part D of the cor-.
rugation on either side, the bottom portion of the mass being naturally riveted by itself through the perforationsH in the web of the.
plate. It will be seen in Fig. 5 that the ends of these lips are really turned back to a position parallel with the general plane of the plate. This is usually accomplished by the pressure employed in forcing the active material upon and into the grid. It will also be seen to be below or upon a level with the outer face F of the plate, as seen in Fig. 5.
The corrugation will be found to be valuable in allowing for the expansion of the material and in directing this expansion into vertical rather than horizontal or lateral lines, there being room above, but not always room laterally at the edges of the plate. The ribs B and edges A are made sufficiently light, so that they will stretch during this process of expansion.
It will be readily understood that while it is designed to use the above parts in the relation shown, yet some may be used without the others, and the invention extends to such use. It will furthermore be readily understood that while the detailed construction has been described with more or less minuteness, yet the invention should be in no wise re-- stricted to the exact methods and details described, but rather should be limited-only in scope as indicated in the claims.
Having thus described my invention,what I claim as new, and desire to secure by Letters Patent, is-
1. An'element for a battery, consisting of a thin plate provided with raised edges, verti cal r bs.
