Abstract
A machine for casting battery grids continuously includes a rotary, cylindrical drum in the outer peripheral surface of which the battery grid cavity is machined in the form of a plurality of intersecting axially and circumferentially extending grooves. A shoe is arranged in close fitting, mating engagement with an arcuate segment of the peripheral surface of the drum. The shoe has a molten lead passageway therein which communicates with the peripheral surface of the drum by means of an orifice slot extending lengthwise of the shoe and across the drum. Molten lead under superatmospheric pressure is directed into a tube extending lengthwise within the lead passageway in the shoe and provided with a plurality of openings spaced lengthwise of the tube. The lead is discharged through these openings into the lead passageway, through the orifice slot and against the surface of the drum. The orifice slot has an upstream edge inclined slightly to the axially extending grooves on the battery grid cavity pattern on the drum. The arcuate surface of the shoe which contacts the peripheral surface of the drum is formed with pockets in which lead solidifies to form a seal between the drum and the shoe.
