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.
Claims19
A hopper car, comprising:
- a body;
- a plurality of discharge chutes along the underside of said body;
- a plurality of sliding gates for closing said discharge chutes;
- means for shifting each of said sliding gates between a first position fully closing said discharge chutes and a second position fully opening said discharge chutes, wherein at least one of said sliding gates travels in the opposite direction from the other sliding gates when moving from said first to said second position;
- a plurality of drive levers coupling said shifting means to said sliding gates;
- and a single activating means, operative in a linear direction, for simultaneously shifting all of said sliding gates from said first to said second position.
A mechanism for actuating sliding gates of a hopper car of the type having a body, a pluraity of discharge chutes along the underside of the body, and a plurality of sliding gates for closing the dischrge chutes, said mechanism comprising:
- means for shifting each of said sliding gates between a first closed position and a second open position, wherein at least one of said sliding gates travels in the opposite direction from the other sliding gates when moving from said first to said second position;
- a plurality of drive levers coupling each of said sliding gates to said shifting means;
- and a sole activating means, located on said underside of said body and operative along a line parallel to the longitudinal axis of said car, for simultaneously shifting all of said sliding gates from said first to said second position.
A mechanism for actuating sliding gates of a hopper car of a type having a body, a center frame member, extending longitudinally along the underside of said body, a plurality of discharge chutes along the underside of the body, and a plurality of sliding gates for closing the discharge chutes, said mechanism comprising:
- means for shifting each of said sliding gates between an open and a closed position, wherein at least one of said sliding gates travels in the opposite direction from the other sliding gates when moving from the closed to the open position;
- a plurality of levers for coupling each of said sliding gates to said shifting means;
- and a single activating means, affixed to said center frame member, containing means capable of linear movement in a direction parallel to the longitudinal axis of said car, for simultaneously shifting all of said sliding gates from said closed to said open position.
