ABSTRACT:
A railway trailer hitch includes a diagonal strut linkage rigidly attached to a bumper block assembly which is pivotably mounted about a pin supported for rotation by a vertical strut. The linkage extends within a hitch diagonal strut. A transversely extending shaft is attached to the lower portion of the linkage. At least one movable locking link is attached to the outer end of the shaft. The movable locking link is adapted to engage at least one fixed locking lug on at least one side of the hitch when the diagonal strut linkage is in the extended position within the diagonal strut. A spring is attached to the diagonal strut and to the diagonal strut linkage biasing the linkage into a downward position within the strut. Guide means are located within the diagonal strut allowing vertical movement of the linkage within the strut as the bumper block rotates about the pin and the linkage is moved longitudinally within the strut against the bias of the spring.
