ABSTRACT:
A tow bar connecting a towed vehicle a towing vehicle has a shaft forking to tines whose hooks to engage the axle or undercarriage of the towed vehicle. A cradle or bracket slidable on the shaft engages the frame, bumper or other part of the towed vehicle. An arm is pivoted to the shaft by the arm's disk-like termini, which rotatingly sandwich the shaft's disk-like terminus. The arm's termini have satellite apertures which register with complementary satellite apertures in the shaft's terminus. Registering of the respective satellite apertures occurs at selected relative angular portions of the arm and shaft. Pins through the registered satellite apertures lock the arm and shaft in a given relative angular position. A jack raises the shaft once the tow bar is on the towed vehicle. The tow bar includes an eye or the like for attaching the tow bar to the hitch of the towing vehicle.
