Apparatus for controlling operation of railroad hopper car discharge doors

摘要

An apparatus for controlling discharge of commodity from a railcar hopper car having a centersill and two laterally spaced door assemblies arranged in registry with two transversely spaced discharge openings on a hopper of the car is disclosed. The doors of the discharge door assemblies are joined to each other by an elongated connector such that they move in unison. The apparatus includes an operating shaft rotatable about a fixed axis extending transverse to and vertically beneath the railcar centersill. A linkage system operably connects the operating shaft to the elongated connector to simultaneously push the door assemblies into their closed position in response to rotation of the operating shaft in a first direction and pulls the door assemblies from their closed position in response to rotation of the operating shaft in a reverse or second direction.
