Abstract
A coke-oven door assembly has a rigid door, a mounting block adjacent the door, a door-plug backing plate fixed to the mounting block, and a membrane having a center portion between the backing and mounting blocks and a periphery juxtaposed with a coke-oven door jamb. A blade-type seal is carried on the periphery and engageable with the door jamb and spring units on the door press the seal against the door jamb. A plurality of bolts threaded into the mounting block extend generally perpendicularly outward from the membrane and are each formed with an abutment shoulder directed outward away from the membrane. A plurality of sleeves threaded into the door slidably receive the bolts and are each formed with an abutment shoulder directed inward toward and engageable with the respective bolt abutment so that the mounting block can move perpendicular to the membrane relative to the door with separation of each bolt abutment from the respective sleeve abutment.
