Trailor hitch

An apparatus for joining a socket member of towed vehicle to a towing vehicle comprising:

• a support member connected to the towing vehicle, said support member having a bore extending transversely therethrough;
• a ball means defining a hollow inner cavity opening on a surface facing said support member, said ball means having a transverse aperture extending through said inner cavity of a right angle;
• an elongated bolt member having a non-threaded upper shank portion and an intermediate threaded portion and a lower non-threaded shank portion, said inner cavity positioned on said non-threaded upper shank portion;
• said lower shank portion being connected to a head remote from said threaded portion, said bolt member extending through said bore in said support member;
• an internally threaded intermediate member separate from said ball means, said intermediate member threaded upon said intermediate threaded portion of said bolt member, said intermediate member sandwiched between said ball means and said support member;
• a bore formed in said upper shank of said bolt member and aligned coaxially with said transverse aperture of said ball means;
• and
• a retaining pin extending through said bore and said transverse aperture of said ball means.

A theft proof coupling of the ball and socket variety adapted to join a towing and a towed vehicle, wherein the coupling is comprised of:

• a support member;
• a bolt having an upper shank defining a transverse bore therethrough, said bolt having an intermediate threaded portion, said bolt having a head remote from said upper shank, said head bearing against a bottom surface of support member;
• a locking element threadedly engaging said intermediate threaded portion and bearing against an upper surface of said support member, said bolt extending through said support member, said threaded intermediate portion and said upper shank extending above said upper surface of said support member;
• a ball means having a partially hollow inner cavity, said inner cavity having an opening facing said support member, said inner cavity shaped to correspond generally to said upper shank, said ball means positioned upon said upper shank, said ball means having an aperture extending therethrough and aligned coaxially with said bore in said upper shank to thereby form a keyway;
• a retaining pin extending through said keyway.
