ABSTRACT:
A friction shock-absorbing draft gear having an elongated body member secured to a base member which forms a housing of such draft gear. An elongated compressible device disposed within an internal cavity of the body member adjacent the base member. A collar member secured to the body member adjacent an open end thereof. At least one friction shoe, having at least one tapered friction surface, frictionally engaging a correspondingly tapered inner friction surface of the collar member. A wedge member, having a tapered surface, engages a correspondingly tapered surface on the friction shoe and applies an outwardly-directed radial force on the friction shoe to maintain such friction shoe in frictional engagement with the collar member. At least one lug, extending inwardly of the collar member, engages the wedge member to lock the at least one friction shoe and the wedge member in place.
