Abstract: A carrier rack is provided for transporting electric storage battery plates through the storage battery manufacturing process. The rack is provided with spaced vertical slots for supporting the plates in upright parallel positions spaced from one another, with the positive and negative plates alternately interspersed with one another, and with the lugs of the positive plates extending upwardly along one side of the rack, and the lugs of the negative plates extending upwardly along the other side of the rack. The lugs on each side of the rack are interconnected at the top of the rack by respective ones of a pair of conductive bars. The rack is immersed in an electrolyte, and an electric voltage is applied across the bars to cause charging current to flow through the plates.

Abstract: A lead-acid aircraft battery including an electric terminal assembly for making connections to the internal electrodes of the battery, the terminal assembly being embedded in the plastic cover of the battery and effectively sealed to the cover so as to prevent corrosion by the acid electrolyte in the battery. In a first embodiment the terminal assembly includes a pair of threaded terminal posts which extend outwardly from the cover; and a receptacle; including a corresponding pair of terminal pins respectively threaded coaxially to the posts, is attached to the cover by screws. In a second embodiment an Elcon type receptacle is molded directly into the cover.

Abstract: A molded plastic receptacle for a lead-acid aircraft battery, or the like, which is adapted to be mounted on the side wall of the battery comprising threaded pin terminals which extend through the receptacle and which are molded to the receptacle. The receptacle is formed of a polycarbonate thermoplastic resin which is sufficiently strong to permit the receptacle to be mounted on the side wall of the battery by screws extending through holes in the receptacle and without any need to provide metal bushings in the holes.
