Modular vehicle coupling

Claim 1

In a modular vehicle which is separable into a tractor module and an implement module the combination comprising, a first coupling plate forming a portion of the tractor module, a second coupling plate forming a portion of the implement module and detachably connectible to the said first coupling plate, the two coupling plates being in confronting position when in coupling relation, the said first coupling plate having a transverse horizontally disposed upper edge and a pair of sloping guide edges adjacent the respective ends of the said upper edge, an upper bracket secured to the said second coupling plate and extending over the said first coupling plate in contact with the said upper edge when the coupling plates are in cOupling relation, the said upper bracket having a downwardly projecting portion adjacent the back surface of the said first coupling plate whereby during a coupling operation movement of the said first coupling plate either forwardly or rearwardly produces movement of the said second coupling plate in the same direction, and a pair of guide brackets secured to the said second coupling plate and located where they are contacted by the said sloping edges on the first coupling plate when the first coupling plate is raised upwardly to bring the said upper edge on the first coupling plate in contact with the said upper bracket on the second coupling plate.
