  • Valve interlock systems for use with railcars
    Patent number: 9623881
    Abstract: A valve interlock system for a railcar including a valve stem locking subsystem that includes a coupling device rotatably coupled to the valve stem. The coupling device is substantially stationary in the longitudinal direction and rotatably translatable about a longitudinal axis and defines an engagement slot thereon. The subsystem also includes a stationary support member extending toward the coupling device in a transverse direction perpendicular to the longitudinal direction and includes a locking member that is transversely translatable and complimentary with the engagement slot. The subsystem also includes a biasing device coupled to the locking member that increases an engagement bias as the locking member is transversely translated away from the engagement slot. The subsystem further includes a valve operator assembly that includes a longitudinally and rotatably translatable body configured to regulate the slot engagement bias as a function of a longitudinal position of the body.
