Abstract

A mechanism for operating slidable gate closures on a bottom-pour vessel. The gates are individual blanks for closing the nozzle in the bottom of the vessel, or orifice gates for permitting pouring. Initially, the blank is positioned in line with the nozzle, while the orifice gate is supported temporarily in the space between the blank and a gate-pulling means. Gates can be loaded into this space without interference from the propelling means, which is located at the opposite side of the vessel. To start pouring, the two gates are pulled toward the propelling means to align the orifice gate with the nozzle and displace the blank. In one embodiment the two gates later can be pushed back along rails to return the blank into alignment with the nozzle to stop pouring, and the orifice gate can be removed or replaced without changing the blank. In another embodiment each time a new gate is pulled into alignment with the nozzle, the displaced gate drops from the mechanism.
