ABSTRACT:
A valve assembly for dispensing a predetermined amount of molten metal to a mold filling ladle of a battery grid casting machine. The valve assembly includes a substantially tubular body having an interior chamber therein. A discharge spout projects downwardly from the chamber. An upwardly opening dispenser cup is positioned within the chamber and is supported for limited sideward displacement. The dispenser cup has a substantially annular valve element positioned in the interior thereof. A supply nozzle projects downwardly through the upper end of the body into said chamber, and projects into the interior of the cup for engagement with the valve member. Relative vertical displacement between the body and the nozzle permits controlled flow of molten metal from the nozzle into the dispenser cup and then into the chamber for discharge through the spout. The cup maintains a predetermined quantity of molten metal therein at all times, even when the valve assembly is closed, so that the valve member is continuously and completely immersed in molten metal.
