Battery filling device. [automatic filling upon pulling a pin]
A battery filling device which, upon manual actuation of a pull ring, automatically transfers liquid electrolyte from a flexible storage container into the cells of a battery. The filling device comprises a housing having chambered sections therein separated by a manifold distributing section. The flexible container and the electrolyte therein are initially contained in an upper chamber. A portion of the container is positioned between the coils of a partially uncoiled portion of a spring metal sheet. The metal sheet is spring formed to roll itself into a cylindrical form when it is unrestrained. The coil is restrained from rolling up upon itself initially by the presence of the filled electrolyte container positioned thereon. Upon actuation of the pull ring, a spring biased valve opens an orifice in the storage container and releases the electrolyte. As the electrolyte disperses through the manifold section to the battery cells located in a lower chamber, the metal sheet coil squeezes the empty section of the flexible container flat so that the spring-biased metal sheet can assume its cylindrical shape by rolling up the flexible container between its coils. The rolling action of the metal sheet helps to squeeze the electrolyte out of the orifice into the distribution manifold. 3 figures. (auth)
