Abstract: A hatch cover system for a railroad car employs a longitudinally extending series or end-to-end main hatch covers wherein each adjacent pair of covers has proximate, concave ends defining a circular port that permits access to the interior of the car when the covers are in their closed positions. A relatively small, circular cover is provided for each port and, in its closed and locked position over the associated port, also serves as a batten to hold the adjacent main covers closed. For operations not requiring that the entire hatch be open, the ports provide easy access to the interior of the car without the need to raise the heavy main covers and swing them to their open positions. The number of hinges required by the cover system is significantly reduced by the use of a special hinge device adjacent each port that serves as a mount for the associated port cover and both or the adjacent main covers.
