Abstract

A coupling hook has a latch which is displaceable into the hook opening in its locked position to block a coupling pin received in a slot formed in a partially spherical member pivotally mounted in the opening. The latch is provided with a surface which engages a coacting surface on the partially spherical member to maintain the latch in its open position. When a coupling pin is received in the slot of the partially spherical member the member will be urged downwardly against a spring and the latch will be disengaged from the partially spherical member. A second spring then urges the latch into its locked position.
