ABSTRACT:
A compact, sealable ladle transport for conveying material from a supply to a chamber, such as a combustion chamber, consists of an elongated ladle member longitudinally moved in a conduit to the combustion chamber by a power driven flexible tape attached to the ladle at one end and having its other end moving out from or back into a storage housing at the end of the conduit. In one position of the ladle material from a supply magazine is loaded onto it; the ladle is then moved forward to carry the material into the combustion chamber. After combustion, as the ladle is drawn back from the chamber, a wiper blade pivotted in the conduit sweeps the combustion residue into a receiving cavity at the bottom of the conduit. A port and passage, with a valve therein, opens into the conduit to provide means for applying purge gas through the conduit and chamber, and generally for controlling the pressure and composition of the atmosphere therein.
