Trailer hitch and method of coupling

    A coupling device which can be readily transferred to other pairs of powered vehicles and unpowered trailer vehicles for over-the-road towing of the trailer vehicle. The device involves modified male and female contoured members such as complemental ball and socket members which can be easily brought together into mating engagement by a uniform cable member passed through continuous openings in both contoured male and female members and is capable of drawing together the paired vehicles into precise alignment and positively seating the coupled members into mating relation with minimal physical effort.
