Description: Patent for a simple, durable, and safe car-coupling that will not accidentally uncouple, and can uncouple without the operator stepping between the cars. It "consists principally of a knuckle pivoted in the drawhead and provided with cam surfaces, and an arm mounted to swing and adapted to engage the said cam surfaces to open and close the knuckle" (lines 14-18). The coupling can also couple cars of different heights.
