ABSTRACT:
A coke oven door for placement against a door jamb of a coke oven comprises a segmented door body and plurality of toggle mechanisms coupled to the door at the juncture of each segment. The toggle mechanisms include inner and outer toggle links pivotally connected by an intermediate pivot shaft and the links are pivotable between an extended length and a shortened length. Inner ends of the toggle mechanism are coupled to the segmented door body and outer ends of the toggle mechanisms are coupled to a flexible latch tension bar. The latch tension bar engages latch hooks connected to the door jamb and vertical movement of a latch actuator rod coupled to the intermediate pivot shaft moves the toggle mechanisms to an extended position to flex the latch tension bars and force the door body against the door jamb to seal the coke oven. Vertical translation of the actuator rod simultaneously extends each toggle mechanism to latch the door, and each latch tension bar provides an independent sealing force on the door such that an improved seal is maintained with better relative parallelism between the door body segments and the door jamb.
