ABSTRACT:
An inexpensive captive operating handle assembly for a bottom operated railway tank car lading valve includes an operating shaft for a bottom operated tank car closure valve. The handle assembly includes a handle connection portion having a non-round slot adapted to engage a valve closure shaft non-round connection portion. An adapter plate is held captive by the outlet chamber and the shaft non-round connection portion. A shaft portion of the handle extends upwardly and away from the connection portion, and is held in place by a bracket located on the outlet chamber or on the tank car. In stored position, the handle connection portion is spaced below the shaft connection portion. The handle is pivotal about a hinge to an engaged position in which the handle connection portion abuts the lower surface of the adapter plate and in which the handle connection portion engages the non-round operating shaft portion to move the valve closure between open and closed positions. The handle is then returned to the stored position after use.
