Abstract
A hitch for a vehicular tow trailer which can be rigidly yet removably attached to a sleeve has a shaft which slides into the sleeve and locks with a pin in a conventional manner. The shaft is divided into two sections that are separated by parallel planes that are inclined to the direction the shaft is inserted in the sleeve. The sections are connected by a bolt which traverses the inclined planes threading into one section while being operable from the outside of the other. Tightening of the bolt causes the sections to slide to opposite sides of the sleeve, wedging the shaft within the sleeve and eliminating play between the shaft and sleeve.
Claims8
In a detachable hitch for a vehicular tow trailer, said hitch having a rigid shaft with an outside surface that slides into an inside surface of a rigid sleeve that is mounted on a towing vehicle, an aperture in the sleeve and an aperture in the shaft that are aligned when the shaft is inserted in the sleeve, and a pin that is inserted through the aperture in the sleeve and the aperture in the shaft to prevent the shaft from sliding out of the sleeve, the improvement comprising:
- (a) a means for transfiguring the shaft to cause a portion of the outside surface of the shaft to press upon a portion of the inside surface of the sleeve;
- and
- (b) a means for controlling the means for transfiguring the shaft to cause a portion of the outside surface of the shaft to press upon a portion of the inside surface of the sleeve.

- (a) a means for transfiguring the shaft to cause a portion of the outside surface of the shaft to press upon a portion of the inside surface of the sleeve which means comprises a division of the shaft into at least two parts;
- such division lies in a plane inclined to the direction that the shaft slides into and out of the sleeve;
- and the parts of the shaft can slide relative to each other along the division;
- and
- (b) a means for controlling the means for transfiguring.
