A mechanism for operating a discharge gate assembly mounted on a railcar. The gate assembly includes a frame defining a discharge opening, a door slidably positioned on the frame for a generally horizontal range of movements between a closed position and an open position. An operating shaft assembly is mounted on the frame for rotation about a fixed axis and is operably coupled to the door such that the door moves in response to rotation of the operating shaft assembly. The mechanism for operating the discharge gate assembly includes a mount carried by and with the railcar and an actuator carried by the mount outside a range of travel of the slidable door. A force transfer mechanism is operated by the actuator for rotating the operating shaft assembly to slidably move the door between the closed and open positions in response to operation of the actuator.

A mechanism for operating one or more hinged doors on a hopper car including an elongated operating shaft having a fixed axis of rotation and a linkage system for operably connecting the operating shaft to the hinged doors on the railroad hopper car. The linkage system includes an actuating link operably connected to and rotatable with the operating shaft and a connecting link for operably connecting the actuating link to each door. The linkage system links includes a primary lock for holding each door in the closed position. A selectively operated secondary lock is rotatable about a fixed axis disposed above the fixed axis of the operating shaft assembly. The secondary lock rotates between a first condition, wherein a stop engages with at least one link of the linkage assembly, and a second condition, wherein each door is permitted to move to the open position. A release mechanism is provided for releasing the primary lock by moving at least one of the links of the linkage system relative to the other thereby allowing the door to be forcibly moved toward their open position under the influence of the columnar load being placed thereon by the lading in the hopper.

An apparatus for controlling the discharge of materials from a railcar having a hopper carried on a mobile frame. The hopper defines a longitudinally disposed discharge opening. The railcar has a door pivotally mounted for movement between an open position and a closed position relative to the discharge opening. The apparatus for controlling the discharge of materials from the railcar includes an operating shaft and a drive operably coupled between the door and the operating shaft for causing the door to move from the closed position toward the open position in response to rotation of the operating shaft. The drive also includes a lost motion connection for protecting the operating shaft as the door freely pivots toward the open position during collapsing movement of the lost motion connection and after the operating shaft has been rotated a predetermined amount to open the door.

Apparatus for controlling discharge of material from a railroad hopper car

A system on a railroad hopper car for providing an indication, observable by a person located either proximate to or remote from the hopper car, of a condition of a lock arranged in operable combination with a mechanism on the hopper car for controlling discharge of material from the hopper car. The system includes electric circuitry and a sensor for providing a signal when each discharge mechanism lock on the railcar is in the locked condition and for producing another signal when each discharge mechanism lock on the railcar is in the unlocked condition. An illuminable indicator, mountable on a side of the railroad hopper car, is responsive to signals from the circuitry for displaying the condition of the discharge mechanism locks. A method for visually displaying a condition of a lock on a railroad hopper car as through use of illumination is also disclosed.

An apparatus for controlling discharge of material from a bottom dump railroad car having a centersill defining a longitudinal axis for the hopper car is disclosed. The apparatus includes a plurality of longitudinally mounted discharge door assemblies. Each door assembly comprises a pair of longitudinally mounted discharge doors disposed to opposite lateral sides of the longitudinal axis of the car for movement between open and closed positions relative to respective discharge openings on a bottom of the car. Each discharge door is mounted for movement about an axis disposed adjacent and extending generally parallel to the longitudinal axis of the car. A door operating mechanism including a positively driven actuator is carried on the hopper car for operating at least one of the discharge door assemblies independently of at least one other discharge door assembly on the car. The door operating mechanism includes a primary lock for inhibiting inadvertent movement of the discharge doors of each door assembly to an open position. A secondary lock, operable in timed relation to the door operating mechanism, is disclosed for releasably maintaining the discharge doors of each discharge door assembly in a closed position.
