Abstract In a self-unloading vessel having hoppers with discharge outlets for discharging either lump or pulverulent material onto an unloading conveyor, discharge apparatus includes a wheeled carriage sup- porting two separate gate assemblies thereon and movable to bring one or the other of the gate as- semblies into discharge relationship with the hopper outlet. One gate assembly includes a horizontally sliding gate which is driven between open and closed positions by a drive cylinder. The other gate as- sembly includes fluidized bed airslide apparatus for directing pulverulent material to a discharge pas- sage closed by a butterfly valve. Two embodiments are disclosed. In one a separate drive cylinder is pro- vided for moving the carriage between its two po- sitions along associated rails. In the other the one gate can be releaseably pinned to the other gate assembly. The relative positions of the two gate assemblies are reversed in the two embodiments.
