An outlet valve assembly is provided for a railway tank car. The valve is mounted at the bottom of the tank car for discharging downwardly between the tracks. The valve is operable between the closed position to occlude flow through the valve and an opened position to permit flow through the valve.

An outlet valve assembly is provided for a railway tank car. The valve is mounted at the bottom of the tank car for discharging downwardly between the tracks. The valve is operable between the closed position to occlude flow through the valve and an opened position to permit flow through the valve. A shaft is operably connected to, and extends from, the valve on a horizontal axis normal to the length of the tank car for being rotated on the axis to operate the valve between the closed and opened positions. A handle is connected to the shaft at a predetermined distance from the valve, and the handle extends generally radially outwardly from the shaft. The valve is operated between the closed and opened positions when the handle is swung through an arc from an initial orientation to a final orientation. The length of the handle and the predetermined distance between the valve and handle connection is selected such that the handle can be swung between the initial and final orientations by a person standing upright beside the tank car outside of the tracks.

In a railway tank car having a generally cylindrical tank supported at its oppositely disposed ends on trucks disposed to ride on railway tracks, an outlet valve assembly comprising: a valve mounted at the bottom of said cylindrical tank for discharging downwardly between the railway tracks and operable between a closed position to occlude flow through said valve and an open position to permit flow through said valve, a shaft operably connected to and extending from said valve on a horizontal axis perpendicular to the longitudinal axis to operate said valve between said closed and open positions; a support means mounted to said tank for supporting said shaft at a region spaced from said valve, said support means includes a bracket assembly comprising a generally vertically oriented channel for receiving a distal end of said shaft, said bracket assembly further includes an upwardly angled strut connecting said channel to said tank; and a handle connected to said shaft at a predetermined distance from said valve for rotation of said shaft, said handle extending generally radially outwardly from said shaft, said handle extending generally radially outwardly from said shaft and connected to said shaft such that swinging of said handle through an arc in a plane parallel to the longitudinal axis of said cylindrical tank is operative to move said valve between said closed and open positions as said handle is swung from an initial orientation to a final orientation, the length of said handle and said predetermined distance between said valve and said handle connection to said shaft being such as to permit a person to swing said handle between its initial orientation and its final orientation while standing outside of the railway tracks.
