Abstract
A railroad freight car coupling system utilizing purely mechanical cushioning assemblies at opposed ends of the car. Each cushioning assembly includes an elongated draft gear assembly including two individually operable and axially spaced assemblies for absorbing both buff and draft forces. Each draft gear assembly includes an axially elongated and hollow metal housing with a first open end and a second open end disposed in longitudinally spaced relation relative to each other. The draft gear assembly is provided with first and second spring biased assemblies at opposed open ends of the housing for absorbing, storing and returning energy directed against a railroad freight car with which the draft gear assembly is arranged in operable combination.
