Machine for continuously casting battery grids

摘要

A machine for casting battery grids in a continuous manner includes a rotary cylindrical drum in the outer peripheral surface of which the battery grid pattern is machined as a cavity. A shoe is arranged against an arcuate segment of the peripheral surface of the drum. An orifice slot in the shoe has an opening at the peripheral surface of the drum. Molten lead under superatmospheric pressure is directed into the orifice slot in an amount in excess of that required to fill the grid cavity on the drum through the opening in the orifice slot as the drum rotates. Means are provided in the shoe for maintaining the molten lead in the orifice slot in a highly fluid condition and for causing the lead filling the grid cavity to solidify rapidly as it advanced beyond the opening of the orifice slot.
