Abstract
A railroad car coupling mechanism is described as having a yoke which is disposed within, I) a carsill which is attached to the underside of a railroad car adjacent each of the opposing ends of the car, and II) a striker which is secured to the subsill and railroad car. The striker and carsill carry front and rear stops between which the yoke extends and engages the front stops. At least one resilient load cushing device is disposed between the straps of the yoke for cushioning loads impacting the car coupling mechanism. At least one wedging device is disposed within the yoke straps, in tandem, with the load cushioning device, for taking up any slack which develops from worn parts within the yoke. At least one wedging mechanism is disposed outside the yoke between the back end of the yoke and the rear stops to, likewise, take up slack and insure that the yoke remains firmly, in place, between the front and rear stops.
