Abstract
A lock is disclosed for charging holes of horizontal coke ovens and for permitting the charging of moist or preheated coal through charging devices, such as longitudinal conveyors fixedly mounted on the battery, or traveling charging cars, while preventing emission. The lock is designed as a spectacle gate accommodated in a casing which is firmly connected to the frame of the charging hole and forms a gastight seal against the connections of the charging devices even during the actuation of the spectacle gate, and with the spectacle gate being actuated through a linkage from outside the casing.
