ABSTRACT:
A device for metering and transferring liquid non-ferrous metals. A hollow sleeve is mounted on a supporting structure and a pouring spout is on one end of the hollow sleeve. An orifice is in the pouring spout communicating with the interior of the sleeve. A stopper rod extends into the sleeve and is shiftable between a position seating on the pouring spout and sealing the orifice therein and a position removed from the pouring spout to permit liquid metal to flow into and out of the hollow sleeve. The parts are made of cast iron and the stopper rod has a tungsten carbide tip for passage through the orifice during the sealing and unsealing thereof to clean the orifice and to prevent foreign matter from collecting in the orifice.
