ABSTRACT:
A railroad hopper car having bottom discharge doors, an elongated beam assembly along the bottom of the car, door operating levers to open and close the doors connected to the beam assembly and doors, and lost motion timing connections in the beam assembly which permits displacement of beam sections to open and close pairs or sets of doors in a sequential but substantially simultaneous and automatic order so ast to permit reduction of air pressure required to open the doors, or permit use of smaller diameter air cylinder, a pneumatic drive to move the beam in opposite directions to open and close the doors, and a secondary lock to maintain the beam stationary unless pneumatic pressure intentionally operates the pneumatic drive, with the lock being positioned to be readily seen when locked and safely operated if necessary from the wayside.
