ABSTRACT:
A knife edge type of sealing means for coke oven doors having edgewise flexibility permitting the knife edge strip to adjust inwardly and outwardly with respect to the plane of the seating surface of the door jamb as the door jamb warps under service conditions due to exposure to oven heat. A number of different forms are disclosed, in several of which the knife edge strip is made up of end-butting or overlapping sections jointed for relative expansive and contractive movement, the strip being tightly held in a transversely slotted retainer support of U-shape in cross-section, which is in turn sealingly secured to a flexible diaphragm member, of either of two forms, attached to the coke oven door. Another form of knife edge sealing strip is partially slotted from the inner edge outwardly while the U-shaped retainer member is expansively jointed. Another form of knife edge has a T-shaped cross-section with the web of the T partially slotted toward the base and joined across the slots by splicing plates expansively attached to the web. In another form, the retainer member of U-shape is diagonally slotted from the outer edge toward the base while the knife edge strip has the inner edge partially slotted outwardly at intervals along the length thereof.
