Patent for a new and improved coupling for railroad cars. This design consists in "[t]he combination, with the draw-head provided with the hole through its under side and the vertical guide-grooves in its exterior sides, of the stirrup sliding in said grooves and provided with a tongue at its lower and hooks at its upper parts, and a lifting-device—such as a rod or bar—adapted to engage with the upper part of the stirrup for raising it in the said external guide-grooves and causing the said tongue to raise the coupling-link in the draw-head" (lines 4-14).
