ABSTRACT:
A machine for casting battery grids has a rotary drum, the pattern of the battery grid cavity being recessed into the outer periphery thereof. An arcuate shoe is fixedly positioned against the rotating drum in sliding contact with the outer peripheral surface thereof. The shoe has an internal passageway connected to an orifice slot which extends to the periphery of the drum. The orifice slot is connected at one end to a source of molten lead under pressure and at its other end to a return line. The molten lead in the orifice slot is under superatmospheric pressure. The rate of flow of the molten lead through the orifice slot is in excess of that required to fill the grid cavity.
