Abstract
In a trailer hitch head, the kingpin opening in the top plate is made sufficiently large that, when the jaws are in closed position, the trailer kingpin engages only the jaws. The jaws thus bear the entire load of horizontal impacts to the hitch head. The jaws are made of hardened steel to bear these loads and, in the front portion, the longitudinal extent of the jaws is enlarged to better react loads applied to the rear of the jaws. The jaws are attached to the top and bottom plates of the head with readily removable fasteners whereby, when the jaws become worn, they may be quickly and easily replaced without taking the hitch and the flat car out of revenue service.
