ABSTRACT:
The specification discloses a vehicular trailer hitch apparatus for converting ball-type trailer hitches to receive the hitch ring of a Lunette-eye trailer tongue. A pair of matching half cylinders are fitted around the ball member, rest on the support for the ball member, and form an inner cylinder. An outer cylinder, received on and releasably pinned to the inner cylinder, provides a receiving area for the pivotal mounting of the hitch ring. A contoured shoulder on the inside of the inner cylinder contacts the ball member to prevent removal of the cylinders from the ball member. At least one projection on the outer cylinder prevents removal of the hitch ring therefrom. Alternately, smaller hitch rings may be pivotally received around the inner cylinder with the outer cylinder secured in an inverted arrangement to retain the hitch ring on the inner cylinder.
