A shock-resistant coupler for a vehicle includes a substantially hollow draft gear tube and a coupler head. The draft gear tube has an inside surface, and the coupler head has a flexible, substantially hollow shank portion. The shank portion has a distal end that extends into one end, or mouth, of the draft gear tube. A collar on the distal end features a predetermined number of longitudinally extending relief grooves. Formed in the shank portion adjacent the distal end thereof are at least two slots that extend longitudinally from the collar. These slots enable the distal end of the shank portion to be compressed inwardly so that the shank portion may be inserted into the draft gear tube. A plurality of shear bolts, directed radially through openings in the draft gear tube and corresponding threaded holes in the collar, enable the shank portion to be secured against the inside surface of the draft gear tube. The mouth of the draft gear tube is preferably internally threaded so that an exteriorly threaded ring or bushing, secured about the shank portion between the collar and the coupler head, can be threaded into the mouth to prevent the coupler head from being pulled from the draft gear tube.

Coupling shock resistant (csr) coupler

A hook-type railroad car coupling includes a hook vertically centered and laterally offset in a pocket opening in the front face and a guide pin and hole at opposite top corners. At one side of the bottom a guide horn extends beyond the hook, the front plate having an opening beside the horn and below the hook. A guide wedge is inside the opening to contact the horn of the mating head and improve the parallelism of the front faces of the heads as they come together.
