ABSTRACT:
An anti-pilferage device is attached to the car body of a railroad flatcar of the type for carrying containers. The device has a mounting plate attached to the car frame at a point adjacent the doors of a container loaded on the car. A barrier is tiltably supported on the mounting plate in a manner which permits free movement if the barrier is bumped during loading of a container. The barrier is movable between a raised, operative position and a lowered, retracted position. A spring biases the barrier to the operative position, wherein it is in the path of a swinging container door to prevent it from being opened. In the retracted position the barrier is below the level of the container floor. A plurality of anti-pilferage devices may be mounted on the car to accommodate containers of various lengths. The barriers are automatically movable between the retracted position and operative position without the need for manual actuation.
