Abstract
A coke oven door has a mainframe, a diaphragm plate mounted on the mainframe, a seal mounted peripherally on the diaphragm plate, and plungers mounted peripherally on the mainframe for applying adjusting force to the seal. The seal is adapted for angular contact with a door jamb, and is backed by individual leaf springs arranged in end-to-end relation which are operable to provide rigidity to the seal when the seal is in contact with the jamb. The seal is locally adjustable with the plungers. The mainframe includes a pair of generally parallel side plates having slots along their lengths and a turnbuckle spanning each slot. The turnbuckles provide for flexing the mainframe into a desired configuration for initial adjustment of the door to a door jamb.
