Apparatus for dispensing measured amounts of molten metal

In apparatus adapted to be mounted on a vat at least partially filled with molten metal for dispensing accurately measured amounts of such metal, a positive displacement hydraulic pump having an inlet opening adapted to be positioned substantially below the lowest level of the molten metal to be held by the vat and an outlet opening extending upwardly to a dispensing point, power means for operating said pump, a pulse generator associated with said pump and generating a plurality of pulses directly proportional to the displacement of said pump, a first pulse counter including means for actuating an electrical circuit when said counter reaches a preset value, means associated with said circuit for deactivating said power means, a probe at said dispensing point which provides said counter an electrical signal when molten metal reaches said point, said counter commencing to count when receiving a signal from said probe whereby after molten metal contacts said probe a preset volume of molten metal will be dispensed.
