Abstract
A storage battery grid consisting of a frame having a lug on the upper edge thereof and spaced from a corner of the frame, a set of wires parallel to one another connecting the side edges of the frame, and a set of radial arms diverging away from the upper edge to connect that upper edge to each of the other three edges of the frame.
Claims8
A storage battery grid which can be produced by casting lead or a lead alloy into an appropriate mold and which comprises:
- (I) a generally rectangular frame consisting of opposed first and second edge members which constitute respectively upper and lower edges of said grid when used in a battery, and opposed third and fourth edge members which constitute side edges of said grid when used in a battery;
- (II) a lug integrally formed on said first member at a location intermediate the midpoint of said first member and the common corner of said first and third members;
- (III) a first plurality of wires parallel to one another and connecting one of said third and fourth members to the other of said third and fourth members or to one of said first and second members;
- and
- (IV) a second plurality of wires constituting an array of arms connected to said first member and diverging from one another such that said first member is connected to each of said second, third and fourth members by at least one of said arms.
