Coke oven door
A door construction is described applicable to the door frame of a coking oven, the frame having a planar sealing surface and the door having sealing means cooperating with the sealing surface. The door construction consists of: a. a diaphragm made of sheet metal having a continuous perimeter flange forming a continuous sealing knife edge, the sealing edge being coincident with a plane and adapted to engage and form a seal with respect to the planar sealing surface of the frame; b. a rigid door plate extending parallel to the diaphragm and spaced therefrom, the plate having holes at spaced locations along the margin of the plate; c. adjustable means secured to the diaphragm at spaced locations adjacent to but spaced inwardly from the flange and in alignment with the holes in the door plate, the adjustable means consisting of threaded studs disposed in the holes of the door plate, each of the studs having one end fixed to the diaphragm and adjustably fixed to the door plate by nuts directly engaging the two side surfaces of the plate, whereby each stud may be adjusted to apply forces to the diaphragm in directions either toward or away from the door plate; d. hinge means for attaching the door to the door frame whereby the door may swing on a vertical axis from open to closed position with the sealing edge of the diaphragm flange engaging the sealing surface of the frame; and e. means for locking the door in closed position, the means including means for applying yieldable force to a central region of the door plate.
