Slackless non-cushioned drawbar arrangement for railway car underframe

In a railway car underframe including a sill structure having laterally spaced upright sill walls and top and bottom walls,

• a bell mouth housing portion provided at a forward portion of said sill structure,
• a cushion pocket spaced rearwardly from said bell mouth housing portion,
• said cushion pocket having a rear stop means,
• a housing structure adapted to fit in said cushion pocket when said underframe is utilized with a drawbar,
• spacer means in said cushion pocket for supporting said housing structure for horizontal movement within said cushion pocket,
• a drawbar mounted on said sill structure,
• said drawbar including an elongated transverse slot,
• a draft key carried by said center sill extending through said slot and supporting said drawbar,
• said drawbar having an impact head projecting into said cushion pocket,
• an impact reaction member engaging said impact head,
• support means on said housing structure for supporting the impact reaction member in a plurality of angular positions responsive to angular movement of the drawbar with respect to the sill structure for maintaining the impact head in engagement with the impact reaction member,
• said housing structure comprising a wall structure rigidly connected together and extending longitudinally within said cushion pocket,
• and means between said housing structure and said stop means for locking said housing structure against horizontal movement in said cushion pocket.

In a railway car underframe including a sill structure having

• laterally spaced upright sill walls and top and bottom walls,
• a cushion pocket assembly having a stop end,
• a housing assembly supported in said pocket assembly for horizontal movement therein,
• said housing assembly comprising laterally spaced side walls, a front wall connected to said side walls, a top wall and a bottom wall,
• a drawbar mounted on said sill structure forwardly of said cushion pocket assembly for vertical and sideways swinging movement,
• said drawbar having an impact end adapted to engage said front wall of said housing assembly,
• said front wall having support means thereon and impact reaction means supported on the support means, said impact reaction means engaging said impact end and said support means pivotably supporting said impact reaction means for maintaining said impact reaction means and said impact end generally flush in engagement during movement of the drawbar relative to the housing assembly,
• interposed means between said housing assembly and said stop end for maintaining said front wall of said housing assembly in engaging position with said impact end of said drawbar regardless of a change in longitudinal dimension of said housing due to wear.
