Abstract
A break-open type firearm having a frame, one or more barrels pivotally mounted on the frame, a barrel lock bolt for releasably locking the barrel at its closed position and a top lever for moving the barrel lock bolt from its barrel locking position to its barrel unlocking position is provided with novel means for retaining the top lever in the lever receiving opening of the frame. The top lever has a vertically elongated lock bolt operating crank that is rotatably received in the lever receiving opening of the frame, the operating crank having a spring strut receiving notch formed therein. The frame has a lever retaining shelf located in the lever receiving opening of the frame and a spring strut retaining shelf located below the lever receiving opening adjacent the upper end of the strut receiving notch of the operating crank. The lever retaining shelf has an operating crank passageway that permits the passage therethrough of the operating crank when the top lever is at its barrel locking position, the lever retaining shelf blocking upward movement of the operating crank and the top lever when the top lever is at its barrel unlocking position. The forward end of the top lever spring strut is received in the strut receiving notch of the operating crank, the strut retaining shelf blocking upward movement of the spring strut and the top lever when the top lever is at its barrel locking position.
