Abstract
A hatch cover for railroad car hatch openings has a body member with inner and outer depending circular flanges. The flanges are located so as to span the loading nozzle or coaming of the hatch. The flanges and body portion define a three-sided pocket between them which receives a removable gasket. The gasket is retained in the pocket by a plurality of clips either integrally molded into the lower edges of the flanges or held by fasteners. The clips extend radially toward the opposite flange. The gasket is sufficiently resilient to allow a user to flex the gasket past the clips during installation and removal of the gasket in and out of the pocket. During opening and closing of the cover the clips retain the gasket in the pocket.
