WILLIAM R. POLK, 0F ATLANTA, GEORGIA.
BAT TERY-GRID.
Application filed June 16,
To all whom it may concern Be it known that l, TVVILLIAM It. POLK, citizen of the United States, residing at Atlanta, in the county of Uekalb and State of Georgia, have invented certain new and useful Improvements in Battery-Grids; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to grids for storage batteries and particularly to double lattice grids.
An object of the present invention is to provide a simple, efficient and light grid of the type indicated adapted to more firmly and effectively hold the paste and to hold a larger amount of paste proportional to its own weightthan possible with other known forms.
A further object is to provide a double latticed grid having spaced faces, capable of being cast in one operation without the use of a core.
The invention consists in the novel structure, combinations and arrangement of parts as hereinafter more particularly described and claimed.
One sheet of drawings accompanies this application as parts thereof, in which like reference characters denote like parts throughout.
Referring to the drawing:
Figure 1 is a plan view of the improved grid,
Fig. 2 is a sectional view taken on the line 29. of Fig. 1,
big. 3 is a sectional view taken on the line 3-3 of Fig. 2, and
Fig. 4c is a side perspective of the device broken away to show the double tapered spacing post.
The improved grid comprises two opposed and spaced lattices having webs a a so arranged that the intersections b of one lattire web are opposite the center of the openmgs c in the other. The walls of the lattice webs are formed with inwardly directed bevels (Z-(Z and spaced by transverse truncated tetrahedral bars 6 connecting adjacent parts of the opposed lattice webs as clearly shown Specification of Letters Patent.
Patented June 7, 1921.
1920. Serial No. 889,405.
in Fig. 2. The transverse bars 6 have their opposing faces tapered in opposite directions, the tapers of the bar 6 corresponding with the bevels (Z-(Z, shown in Fig. 4. I
These spaced latticed webs are surrounded by an integral border strip 7 which forms the side walls for the paste inclosed between the two webs. On one side, this border ta:
the paste which is firmly secured between the spaced webs in the form of a plate, and extending through the openings in each web flush with their outer faces. The staggering of the intersections of the lattice on the opposed faces operates to utilize the intersection of one face as backing for the paste more largely exposed by the opening in the opposed face. 7
Modifications in the form of the lattice work openings may obviously be made within the scope of the present invention.
What I claim is:
1. A grid comprising two latticed webs arranged with intersections of one opposite the openings in the other, said webs having their sides beveled inwardly and transverse posts intermediate the web intersections connecting adjacent portions of said webs and spacing the same.
2. A grid comprising two latticed webs adjacent but spaced from each other and arranged with their intersections in offset relation, the sides of said lattices being inwardly beveled, and transverse spacing members having their opposing faces oppositely tapered integral with said webs connecting the web bars intermediate their intersections and spacing the webs.
8. A grid comprising two latticed webs arranged in spaced and staggered relation to each. other, each of said lattices having the Walls of its Openings beveled inwardly.
and truncated tetrahedral and cross posts connecting adjacent parts of said Webs intermediate their respective intersections, said 5 cross posts being tapered in opposite directions corresponding to the bevels of the respective Web Walls.
4. A grid comprising tWo latticed Webs arranged in spaced and staggered relation to each other, and spacing posts connecting 10 said Walls intermediate their respective intersections, to reinforce and space the Webs.
In testimony whereof I afiiX my signature.
WILLIAM R. POLK.
