Abstract
An apparatus for sealing the air gap between a leveler bar and the chuck door opening in a coke oven having spring loaded rollers as side and top seals between the leveler bar and a surrounding smoke seal box. The smoke seal box is pressed into a sealing engagement with the frame surrounding the chuck door opening via a spring plate assembly. Also a swing gate assembly provides a coal seal between the bottom of the smoke seal and the bottom of the leveler bar.
