ABSTRACT:
Novel quick opening removable tray sections or deck plates for trays of fluid contact vessels having foldable closures or covers adapted to rest upon frame members which coact to form perimeters of one or more polygonal, preferably quadrangular, complementary openings in each tray. Each cover has at least a pair of closure panels hingedly connected at their adjacent inner margins. Opposed outer lateral or side margins of closure panels, which overlie complementary lateral or side frame members in spaced relationship, extend in the same general direction as their adjacent inner margins. At least one of opposed outer lateral margins is slidably confined whereby cover is removable upon elevating closure panels at their hinged inner margins and simultaneously sliding said outer lateral panel margins toward each other and out of confinement so as to permit folding of said cover. If desired, one of opposed outer lateral margins of closure panels may be hingedly connected to adjacent edge portion of tray instead of being slidably confined. Frictional fasteners detachably secure end margins of closure panels adjacent their hinged connection to underlying portions of end frame members at opposed ends of tray opening. Any of the deck plates of a tray may be removably mounted in this manner.
