<p>An uncoupling lever assembly for railroad cars that includes an uncoupling lever with an improved slideway arrangement for accommodating extension and contraction of the lever assembly, which lever assembly comprises a handle section and a lock lifter section each including an elongate rectilinear bar. The handle section bar has an operating handle affixed to one end of same for pivotal connection to the car and the lock lifter section bar has a lock lifter rod member affixed to one end of same having a hook eye adapted for application to the coupler lock lifter. The lock lifter bar has secured to one side of same adjacent its other end a single elongate tubular member that defines a single slideway for the lever assembly having self-lubricating antifriction characteristics in which the handle section bar is slidably received. The lever assembly bars are in side by side relation, with the slideway forming tubular member being slidably mounted on the handle section bar, and the handle section bar projecting through the slideway and inboard of same when the coupler is in its neutral centered relation relative to the car.</p> |
