  • Patent number: 5398750
    Abstract: The machine includes a train of molds moving through an arcuate pouring zone, a supply vessel for the metal, a trough extending between the vessel and the mold trains to convey the metal therebetween. The metal is discharged from beneath the surface of the metal in the vessel and into one end of the trough beneath the surface of the metal therein. The other end of the trough is registered with a mold in the trains and moves with the trains while metal is dispensed into the mold from beneath the surface of the metal in the trough. Valves control the discharging and dispensing of the metal to and from the trough. A motor moves the trough, as needed, in the pouring cycle, and a coupler coordinates the movement of the trough and the mold to keep them registered in the pouring zone.
