Abstract
Abstract A battery case assembly accomodating any desired number of individual cell containers of rectangular metallic construction comprises plastic side cover plates on the individual containers having interengaging flanged edges fitting between the containers. The successive side cover plates are locked together by clasps hooked into undercut edges along the flanged sides of the plates. Tie bars between containers are anchored at their ends in the side cover plates to prevent bulging of the side cover assembly, and metal bosses extending from the sides of the containers engage openings in the side cover plates to permit the cells to be picked up by handles secured to the side cover assembly.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
175 words
A battery comprising a preselected number of individual cells each having a metal container of rectangular shape as viewed from the sides and top permitting the cells to be set in a row with uniform spacing therebetween, a pair of outer plastic side cover plates for each cell having inwardly extending flanges along the sides embracing the container of the cell, the outside walls of said flanges of each side cover plate being complimentarily shaped causing the successive side wall covers to interengage with each other, the exterior wall of each plastic side cover plate having vertical undercut edges adjacent the opposite sides of the plate throughout an upper portion of the plates, straplike clasps having hook-shaped flanges along the opposite sides thereof engaging respective pairs of adjacent edges for rigidly connecting said side cover plates together into an integral side cover assembly at each side of said row of cells with the adjoining flanges of the successive side cover plates establishing the spacing between adjacent cells, and means clamping said side cover assemblies together.
Claim 2
Dependent Claim
175 words
A battery comprising a preselected number of individual cells each having a metal container of rectangular shape as viewed from the sides and top permitting the cells to be set in a row with uniform spacing therebetween, a pair of outer plastic side cover plates for each cell having inwardly extending flanges along the sides embracing the container of the cell, the outside walls of said flanges of each side cover plate being complimentarily shaped causing the successive side wall covers to interengage with each other, the exterior wall of each plastic side cover plate having vertical undercut edges adjacent the opposite sides of the plate throughout an upper portion of the plates, straplike clasps having hook-shaped flanges along the opposite sides thereof engaging respective pairs of adjacent edges for rigidly connecting said side cover plates together into an integral side cover assembly at each side of said row of cells with the adjoining flanges of the successive side cover plates establishing the spacing between adjacent cells, and means clamping said side cover assemblies together.
Claim 3
Dependent Claim
113 words
The battery set forth in claim 1 wherein each of said side cover plates has exterior ribs along said flanged edges of the plates providing said undercut edges at the sides of the ribs away from the respective side edges of the plates, and wherein said clasps have lugs bent inwardly from the top and bottom thereof embracing the ends of said ribs to lock said clasps in place on said side cover plates, including handle structures at the ends of said battery having hooked flanges embracing the ribs of the end cover plates of the battery for enabling the cells of the battery to be carried via said side cover plate assemblies.
Claim 4
Dependent Claim
42 words
The battery set forth in claim 1 including tie bars between adjacent cells anchored at the ends jointly into the contiguous flanges of the respective pairs of adjoining side cover plates to retain the side cover plates against the battery cell container.
Claim 5
Dependent Claim
103 words
The battery set forth in claim 1 including tie bars between adjacent cells anchored at the ends into the contiguous flanges of the respective pairs of adjoining side cover plates of the battery, wherein each tie bar has a head at each end of enlarged cross section, and the contiguous walls of the flanges of the adjoining side cover plates are notched to receive said bars at the parting line between the plates and are recessed in the outer wall to receive the heads of said tie bars in locking engagement with each pair of plates when said interlocking clasps are in place.
Claim 6
Dependent Claim
28 words
The battery set forth in claim 4 wherein said recesses receiving the heads of said tie bars are covered by said clasps when the clasps are in place.
Claim 7
Dependent Claim
50 words
The battery set forth in claim 1 including an aperture in each of the side wall cover plates, and an integral boss on the respective side of each cell container engaging said aperture to lock the respective cover plate against displacement in a vertical plane relative to the cell container.
