ABSTRACT:
A hitch for connecting a trailer to a tow vehicle includes a hitch bar which projects from the tow vehicle and a hitch box which receives the end of the hitch bar and is coupled to one trailer through a hitch ball and a socket-type coupler. The hitch bar has a shank provided along its four sides with beveled surfaces that are presented outwardly and rearwardly. The hitch box, on the other hand, has a box-like enclosure provided with a forwardly presented open end through which the shank of the hitch bar projects. The enclosure furthermore contains beveled surfaces which conform to the beveled surfaces on the hitch bar shank and indeed seat against those surfaces when the hitch bar is fully inserted into the hitch box. The beveled surfaces of the hitch bar and box are maintained in this seated condition by over center clamps, and when so seated, the hitch box will not shift relative to the hitch bar. The beveled surfaces however facilitate connecting the hitch bar to the hitch box while the latter is coupled to the trailer, for they guide the hitch box into precise alignment with the hitch bar when the hitch bar is forced rearwardly into the hitch box.
