Abstract:

An apparatus for the coupling of lines between a tractor and a trailer comprises a tractor plate formed in a generally rectangular configuration with parallel side edges extending vertically and with a lower edge having a downwardly extending tongue and an upwardly extending enlarged head. The tractor plate further comprises vertically aligned apertures. A trailer plate in a generally rectangular configuration has vertically extending parallel side edges and generally parallel upper and lower edges, flanges extending forwardly from the side edges thereof adapted to receive the side edges of the tractor plate, and further includes an enlargement with a recess at its lower edge adapted to receive the tongue of the tractor plate for the support thereof. The flanges of the trailer plate have apertures at the upper edge thereof with a pivot pin extending therethrough. A retainer block supported by the pivot pin is adapted to receive and support the head at the upper edge of the tractor plate during operation and use.
