Abstract
Disclosed is a tubular device for preventing the egress of gases evolved in an oven chamber during the charging thereof. The tubular device is moved into an operative location forming a hermetic seal with leveling openings in the doors for two adjacent oven chambers, one of which is to receive a coal charge. The gases evolved during the charging operation pass into the adjacent oven chamber where carbonization has proceeded to an advanced state. The tubular device includes two tubular front parts engageable with the leveling openings of coke oven doors, a U-shaped connecting member, and a tubular rear part which is disposed to receive a leveler which can extend through the rear part and into an oven chamber. A flap is raised from a normally-closed position in the rear part of the device by movement of the leveler bar therein. A truck on which the tubular device is mounted can move in a direction of the oven chamber axis on tracks disposed on a frame for the leveler.
