Patent number: 4015720Abstract: Apparatus for automatically coupling pneumatic brake lines on railway wagons and other articulated vehicles. The apparatus comprises an axially and resiliently compressible tubular projection which is fitted to the end of the vehicle to extend outwardly beyond the coupling plane of the vehicle.
