Patent for a new and improved coupling for railroad-cars. This design consists in "an ordinary draw-head provided with the usual pin-and-link coupling [that] can be readily and cheaply adapted for use as an automatic coupling. The invention consists in the combination, with a slotted draw-head and a coupling-pin swinging therein and provided with pivotal supports or trunnions, of a vertically-projecting and axially-rotatable guide loop or staple arranged on each side of the pin-slot and adapted to hold the pin from being jolted out of the draw-head, and to permit its withdrawal" (lines 9-20).
