Burton, R E

This patent describes a system for burning wood and other fuel materials: an elongated, pivotally mounted burning chamber having inlet and outlet ends and being capable of being tilted to different angles of inclination to facilitate movement of material through the chamber, an accumulation chamber at the inlet end of the burning chamber, a hopper for receiving fuel material to be burned, an air lock chamber positioned between the hopper and the accumulation chamber, a first gate between the hopper and the air lock chamber for passing the fuel material from the hopper to the air lock chamber when opened and preventing the passage of smoke from the air lock chamber to the hopper when closed, a second gate between the air lock chamber and the accumulation chamber for passing the fuel material from the air lock chamber to the accumulation chamber when opened and preventing the passage of smoke from the burning chamber to the air lock chamber when closed, and means for pushing the fuel material from the accumulation chamber into the inlet end of the burning chamber and thereby causing material already in the chamber to move down the inclined chamber toward the outlet end.
