ABSTRACT:
An uncoupling device (10) is provided with a handle (12) which is pivotably mounted on a bracket at the side of the car. The handle is connected to a bar (16) extending transversely of the car, at a level below a coupler extending out of a center sill. An uncoupling member (42) is slidingly attached to the bar with a connection allowing the uncoupler to slide longitudinally with respect to the bar when the coupler moves, and at the same time has sufficient interface with the bar to transmit torsion to the coupler (34) at a given position on the bar during rotation for uncoupling. The bar includes a stop (68) at its outer end to prevent the coupler member from escaping. The uncoupler member at its outer end includes an upwardly extending portion (70) having a hook (74) which is inserted into the opening (76) in a conventional E type coupler connection to operate the lock lifter mechanism (78) and disconnect coupled couplers. In order to avoid interference between the coupler connection and the hook when the coupler shank is rotated significantly off the center line of the car, the hook portion has a reduced thickness (90) on its outer external surface.
