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. The vent terminates in an exit port having an effective diameter of no more than 0.5 thousand inch.
