Abstract: The apparatus includes a battery support for supporting a battery at a fill position, a head assembly with a plurality of heads each with an opening formed therethrough, an acid tank, a circulating conduit with a pump for circulating acid, and a valve for stopping the circulation of acid. The head assembly is moved from an upper position to a lower position for engaging the head openings with the upper cell openings of the battery. A plurality of fill conduits extend from the circulating conduit between the pump and the valve to the heads for injecting acid into the battery openings by way of the head openings. A plurality of leveling tubes extend through the head openings and beyond the lower ends of the heads for with removing excess acid by way of a plurality of leveling chambers operated together with a piston.

Abstract: A system for casting straps and terminals on lugs of storage batteries includes a loading station including means for receiving at least one non-metallic battery case having a plurality of plates and separators partially inserted in the case with lugs extending out of the case. Clamping structure holds the battery case in position and includes metallic structure for overlying edges of the case to insulate the edges of the battery case from heat. Means rotates the receiving means to position the lugs in a downward substantially vertical direction. Included is a casting mold for receiving molten lead. Transportation means moves the receiving means over the casting molds and lower the lugs into the casting mold. Following the setting of the lead, the receiving means is transported to an un-loading station where the battery case is removed from the receiving means. The casting mold includes a vent for letting air from the mold as molten lead is added to the mold.

Abstract: A pot of molten lead is situated adjacent to a mold chamber containing a mold. A displacement piston is lowered into the pot to displace lead into the mold chamber to fill the mold. The displacement piston them allows the lead to flow back into the pot, leaving the lead in the mold. A battery handler then lowers a battery into the mold to cast lead straps onto the lugs of the battery. Water is forced through a passageway in the mold chamber to cool the lead in the mold. Air is then forced through the passageway to remove the water. The battery handler then removes the battery from the mold and a heating unit begins to preheat the mold chamber for the next battery.
