Abstract
A railway car is disclosed. The railway car comprises an underframe and at least one compartment for transporting lading. The railway car comprises at least one discharge opening and a door assembly adjacent to the at least one discharge opening. The railway car comprises a discharge control system comprising at least a common linkage mounted away from a longitudinal centerline of the railway car and a secondary linkage, wherein the discharge control system is operable to move the door assembly between a first position and a second position. The railway car comprises an actuator operable to drive movement of the common linkage in connection with movement of the door assembly between the first position and the second position.
Claims21
A railway car, comprising:
- an underframe, the underframe comprising a side sill oriented parallel to a longitudinal axis of the railway car and positioned proximate to a lower portion of the railway car;
- at least one sidewall assembly coupled to the underframe;
- at least one compartment for transporting lading;
- at least one discharge opening;
- a door assembly adjacent to the at least one discharge opening;
- a discharge control system comprising at least a common linkage and a secondary linkage, wherein:
- the discharge control system is operable to move the door assembly between a first position and a second position;
- and
- the common linkage of the discharge control system is mounted to the railway car using at least one hangar support, wherein the hangar support is shaped to allow at least one of rotation of the common linkage within the hangar support and movement of the common linkage parallel to longitudinal axis of the railway car.

- at least one sidewall assembly coupled to the underframe;
- at least one compartment for transporting lading;
- at least one discharge opening;
- a door assembly adjacent to the at least one discharge opening, the door assembly comprising at least one door hinge;
- a discharge control system comprising at least a common linkage and a secondary linkage, wherein:
- the discharge control system is operable to move the door assembly between a first position and a second position;
- and
- the common linkage of the discharge control system and the door hinge are mounted to the railway car using at least one hangar support, wherein the hangar support is shaped to allow rotation of the door hinge within the hangar support and allow at least one of rotation of the common linkage within the hangar support and movement of the common linkage parallel to longitudinal axis of the railway car.
