  • Patent number: 4266799
    Abstract: In an adjustable trailer hitch device, a shank is adjustably receivable in a tube of a towing vehicle and terminates in an apertured plate inclined to the vertical. A second apertured plate is attachable by bolts to the first plate in any of a plurality of different positions to provide a plurality of different heights relative to the shank of a towing ball supported from the second plate. The shank and plates are invertible relative to the tube and the towing ball to double the number of heights which the ball may have with respect to the vehicle. The inclination of the plates provides desired clearances for a trailer coupling and allows use of less material without reducing the strength and rigidity of the device.

  • Patent number: 4032170
    Abstract: The invention provides a kit of parts, and a procedure for welding together such parts, to provide a strong trailer hitch for cars. The components of the hitch are such that they can be welded together in various different configurations so as to fit the large majority of cars, station wagons, pickup trucks and vans manufactured in North America. One feature of the hitch is that the socket member which receives the ball assembly is welded into a central tubular member forming part of a cross member of the hitch, and is weldable within this tubular member in different positions to suit required positioning of the ball member.
