Jar for industrial battery

A plate support bridge for an electric storage battery cell jar having a base, adjacent perpendicular side walls and opposite parallel side walls, and including a plurality of elongate support members positioned on the base of the jar for supporting at least one battery plate in spaced-apart relation above the base. A first array of said support members is provided having a first end adjacent to one of the side walls of the jar and extending outwardly from said side wall at an oblique angle thereto and terminating at a second end remote from any side wall of the jar. The first array of support members is spaced-apart from each other at all points along their respective lengths. A second array of said support members is provided and is positioned intermediate said side walls and has at least one segment positioned at an angle oblique to said side walls. The second array of support members is spaced-apart from each other at all points along their respective lengths. The first array of said support members and said second array of said support members are collectively spaced on the base of the jar to support each of the plates therein.

Jar for industrial electric storage battery

The present invention is directed to a leak resistant battery cover for storage batteries. The battery cover provides a labyrinth of passages which provide a path from each cell vent to the atmospheric vent. The labyrinth is configured to provide a portion of each path above a level in which the electrolyte in the respective cells attains when the battery is tipped on any one of its sides or rotated ninety (90) degrees from an upright position. The labyrinth configuration prevents electrolyte from reaching the atmospheric vent and spilling out of the battery.

Leak resistant battery cover

The present invention is directed to a leak resistant battery cover for storage batteries. The battery cover sealably engages a conventional battery housing having multiple cells separated by internal housing walls. The cover has a substantially flat interior area, a portion of which extends over part of each battery cell when the cover is placed upon a battery housing. The cover includes a cell chamber for each battery cell. Drain-back/vents communicate each cell chamber with its corresponding battery cell. The drain-back/vent, whether separate or integrated allows escape of electrolyte gases from the battery cells into the corresponding battery chamber and provide for the return of liquid electrolyte back to the cells from the cell chambers. None of the cell chambers communicate directly through the battery cover to atmosphere. One or more additional chambers are provided in the cover above the central cells of the battery housing. These additional chambers are in a geometrically central area of the battery cover away from the outside perimeter of the cover. Unlike the cell chambers, the additional chambers directly communicate with atmosphere through a convoluted passage and atmospheric vent. Additionally, each additional chamber includes a drain-back/vent directly communicating with one of the central most cells in the battery housing. Thus, the central most cells communicate with the most central cell chambers and the additional chamber. The remaining battery cells do not communicate with the additional chambers.
