ABSTRACT:
An apparatus for delivering molten lead or a lead alloy to the cast-on-strap molds used in the manufacture and assembly of lead-acid batteries is disclosed which comprises a lead delivery member having a lead reservoir of the molten lead or lead alloy, at least one nozzle communicating with the lead reservoir and having an outlet, a valve for each nozzle which controls the amount of lead delivered to the molds when the apparatus is in a lead delivery position, and a heater for maintaining the molten lead at a selected temperature, a frame structure for mounting the apparatus to allow the lead supply member to be rotated between the lead delivery position and a home or wait position about an axis of rotation, a stepper motor and a right angle gear reducer to rotate the lead supply member between the respective positions, the lead reservoir being positioned sufficiently close to the axis of rotation so as to allow movement of the lead delivery member at a selected rate between the lead delivery and wait positions, and the outlet of the nozzle being positioned directly above the cast-on-strap mold when the lead supply member is in the lead delivery position.
