ABSTRACT:
An articulation coupling includes a female coupling having a pair of members each forming a portion of an aperture to receive the male coupling and supported for horizontal movement. A structure, for example, a wedge, is provided for biasing the first female member along the longitudinal axis towards the male coupling and elements secure the second member to prevent movement along the longitudinal axis after mating. The first and second female members are of identical structures and each are capable of both receiving a wedge to produce the biasing as well as a pin or other securements. The wedge extends vertically and a spring biases the wedge vertically and maintains it on the car. Preferably the wedge is made up of two segments and provides a pin or other structure for mounting shims between the segments if necessary to accommodate for wear over time.
