ABSTRACT:
A battenless hatch cover assembly for railcars. The assembly includes a series of hatch covers aligned end to end to cover an opening in a railcar. Each of the hatch covers is hinged along one side to the railcar, with this one side being common among the hatch covers. In an alternative embodiment, appropriate mechanisms could be used to selectively hinge the covers along both sides. The typical cover includes one longitudinal end having a male portion in the form of an upstanding lateral lip. The other longitudinal end is provided with a female portion in the form of a laterally extending downward directed channel. This female portion is adapted to overlie the male portions in a substantially mating configuration. A seal material is provided on the underside of the female portion to engage the male portion and provide an effective seal, and the female portion is sufficiently rugged to apply a sealing pressure upon the male portion. The hatch covers are arranged such that the female portion of the hatch covers overlies the male portion of an adjacent hatch cover. This arrangement eliminates the need for separate or independent battens to apply a seal between the hatch covers.
