Abstract
An improved lever assembly for uncoupling railroad cars having a coupler that includes a lock lifter. The lever assembly has a handle on one end that is pivotally connected to the railcar and a hook located at the other end of the lever assembly that is connected to the lock lifter. The assembly has levers that slide relative to each other. The levers are held adjacent to each other by enclosures through which the levers slide. The enclosures contain U-shaped glides held stationary relative to the enclosures. Typically made of plastic, the glides provide low friction sliding contact with levers sliding through them. The glides are longitudinally shorter than their containing enclosures providing protection from ultraviolet light.
