Abstract
An actuating mechanism for operating sliding gates of a railway hopper car which opens all the gates simultaneously, regardless of the direction which the gates must move to open. While moving in one direction, a shifting means coupled to each gate by means of pivoted levers moves some gates in one direction to the open position, while at least one gate moves to its open position in the opposing direction. The mechanism which shifts all the gates simultaneously is activated from one power source.
