Abstract
The trailer hitch comprises an arm mounted on a motor vehicle through a horizontal, transversal pivot, and having a rear, free end distant from the pivot and formed with an arcuate, convex surface for supporting the draw pole of the trailer. The draw pole has its front, free end provided with a coupling ring. The arm is rotated about its horizontal pivot with the arcuate surface supporting the draw pole in order to successively lift and lower the pole free end and therefore the coupling ring and thereby enable engagement of the coupling ring with an upwardly projecting pintle hook secured to the motor vehicle. Engagement of the coupling ring with the pintle hook hitches the trailer to the vehicle.
