ABSTRACT:
A mechanical device for releasing a bow string in archery, involving a housing, a nib mounted in the housing, a holding cord wrapped around the bow string and held by the nib, and a trigger actuated sear mechanism controlling release of the nib. The nib is on a nib bar which is pivoted at an intermediate portion. A sear bar is pivotally mounted in the housing for movement away from the nib bar. Said sear bar engages the edge of the nib bar to prevent same from pivoting. A trigger is pivotally mounted in the housing intermediate its ends. The trigger has one end which engages the sear and is removed from the sear by manual actuation of the trigger. The movement of the sear by the trigger causes the sear to release the nib, the latter then rotating about its axis to release a bow string which is being held by a looped cord attached to the housing.
