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.
