ABSTRACT:
An improved articulated connector or coupler in which the connection between the male connecting member and female connecting member via a king pin is provided with an elastomeric bushing housed in the male connecting member. The bushing has an outer metallic ring, and inner metallic ring, and a middle ring of elastomeric material, by which a coupling free of uncontrolled slack is achieved and by which all normal draft and buffing, as well as train-action and angling, forces, are damped and partially absorbed by the elastomeric ring. For excessive loads, in order to protect the elastomeric ring, over solid metal-to-metal stops are provided which shunt the force transmittal from the eleastomeric ring to metal stop-surfaces. The king pin is also frustro-conical in shape at the intermediate portion thereof passing through the bushing of the male connecting member, which bushing has a similarly-shaped frustro-conical passageway.
