ABSTRACT:
A railway car underframe center sill includes a drawbar structure which includes a rigid housing structure adapted to fit into the cushion pocket of the sill supporting the cushion. The rigid housing is readily removable if desired and includes a rigid end plate having a truncated opening which contains a truncated hemispherical reaction member which pivots in any direction. The drawbar is supported on the center sill for movement in true rotation and is provided at its inner end with an impact head at all times in flush contact with the hemispherical reaction member. The end of the drawbar includes a drawbar key structure secured in place by means of the draft key. The housing structure is securely maintained in position against a stop by a wedge member which is self-adjusting downwardly as wear may occur and thus insures a contact rigid effective assembly.
This assembly provides a slackless condition in the drawbar attachment between companion units of a railway freight car.
