ABSTRACT:
A hitch or towing device to connect a trailer having at least two swivelable ground-contacting wheels to an automobile or similar prime mover includes two arms to connect the trailer to the prime mover. The arms are flexible in a vertical direction but rigid in a longitudinal and in a sidewise direction. This permits the automobile to push the trailer backwards and also permits relative motion between the trailer and the automobile in roll and pitch but not in yaw. In a preferred embodiment the arms connecting the trailer to the automobile are leaf springs, and couplings permanently fastened to the automobile engage the front end of the springs in a hinge-like manner, the hinge-pin being easily removable to facilitate connecting and disconnecting of trailer and automobile.
