ABSTRACT:
Disclosed is an adapter for modifying a hitch connection between two vehis wherein one vehicle has a hook and another vehicle has a hitch lunette configured to receive the hook. The adapter includes a beam having an adapter lunette on one end swingably engaging the hook and chains to limit the beam's swing about the hook outboard of the one vehicle. At the other end of the beam is a plate to which are fixed flat parallel jaw members, which closely receive the vehicle lunette. The plate bears against the other end of the beam and pivots about a stud on the other end of the beam that extends through the plate. A nut on the stud presses the plate against the other end of the beam with a selected force to achieve controlled resistance to pivoting of the plate.
