ABSTRACT:
A fifth wheel mechanism is fabricated from lightweight aluminum in a high strength box configuration. Locking jaws are spring urged toward the king pin receiving opening and are held open by a clip which is removed as the king pin is inserted into the king pin receiving opening. Wedges are automatically pushed between the inserted jaws and skid plates fastened to side plates of the box frame. A cushion block separates the inner king pin mounting jaw to cushion against impact during insertion of the king pin.
