[Also in Groups XXVI and XXIXJ Metal-metering apparatus for transferring molten metal from a reservoir comprises a pump submerged in the molten metal in the reservoir and having a delivery nozzle extending up and out of the molten metal, holding means having one position for maintaining the delivery nozzle full of molten metal when no delivery is required, and another position providing an open passage through the pump apparatus when transfer of molten metal is desired and means for moving said holding means to one or other of said positions. The molten metal, e.g. magnesium, is held in a closed pot 12, and is discharged through an electrically heated nozzle 28 to the cold chamber 32 of a die-casting machine, by a centrifugal pump 22 driven by an air-motor 26. A double-acting ball valve 34 actuated by an air cylinder 40 is submerged in the melt and feeds the output of the pump to either the nozzle 28 or back to the pot through the orifice 42. The region above the melt may be filled with an inert gas such as SO 2 , neon or argon, introduced through a pipe 54, or a cover of flux may be used on the metal. Inert gas may also be supplied through a pipe 56 to shield the pouring jet. Air supplies to the pump motor and valve cylinder are controlled by solenoidactuated valves, and the valve for the pump motor is preferably by-passed by a low-speed valve which by-passes sufficient air to maintain a slow-speed operation of the pump between deliveries. Alternatively the pump motor may operate continuously at low or high speed. The control circuit may include timing devices to control the amount of metal delivered, and also to open the valve 34 after the pump motor has speeded up to delivery speed, and close it while the pump motor is still at full speed. Alternatively the delivery may be controlled non-automatically by manual operation of a pushbutton. In a modification, Fig. 3, the nozzle is constricted to reduce the area of metal exposed to the atmosphere at the end of a delivery cycle.
