ABSTRACT:
Disclosed herein is a pneumatic molten metal sampler for pneumatically obtaining a sample of metal which includes an elongated fill tube which is secured to the side of a paperboard sleeve by refractory cement and projects beyond the end of the paperboard sleeve for immersion in a molten melt. A bend on the fill tube discharges into the sample cavity intermediate the ends of the cavity. A vent construction at the end of the cartridge affords communication with a vacuum pump but prevents loss of metal from the sample cavity.
