  • Patent number: 4485931
    Abstract: A buffer coupling for rail vehicles comprises a first coupling part which has a receiving shoulder adjacent its end with a first cylindrical portion spaced from the end of said first coupling part of increased diameter from said shoulder and forming a rib in a second cylindrical portion of smaller diameter than the rib forming a cylindrical slide surface over which a sleeve is slidable. The sleeve is urged away from the rib by a spring so that it projects outwardly from the second cylindrical portion of smaller diameter so that it may engage over respective legs of a forked end of the second coupling part which engages with the first coupling part so that the shoulder of the first part fits within the legs of the second coupling part. The sleeve is urged by the spring to engage over the outer cylindrical surface of the second coupling part.
