Truck hitch

Apparatus for effecting a driving connection between a pushing vehicle and a pushed vehicle having broad overhanging wheel rims defining outwardly facing wheel rim chambers, said apparatus comprising;

• a pair of sort pushers attachable to and providing bumper formations on the leading end of the said pushing vehicle, said pushers being spaced apart for respective pushing engagement with the wheels on the corresponding sides of said pushed vehicle,
• each said pusher including an individual frame pivotally and closely attachable to the leading end of the said pushing vehicle for left and right deflection about a vertical axis for alignment with the wheel engaged thereby independently of the alignment of the other pusher,
• a coupler slidably carried by said frame for reciprocable sliding movement in a substantially horizontal direction transversely of said pushing vehicle,
• an arm forming part of said coupler having a free end normally extending forwardly of said frame,
• a lateral projection on said free end extending transversely of said pushing vehicle and spaced from said frame to enable said lateral projection to be positioned, by said sliding movement of said coupler, within said wheel rim chamber of said pushed vehicle for transmission of a pulling force from said pushed vehicle to said pushing vehicle and means for laterally moving said coupler into and out of said wheel rim chamber;
• the effective length of the arm being somewhat less than the combined dimensions of the diameter of the wheel rim chamber and the thickness of the tire between its circumference and said chamber affording substantial displacement of the lateral projection therein.
