ABSTRACT:
A detent assembly at the breech of a gun having a single-shot, tip-up barrel normally holds the barrel in a closed, firing position, yet permits it to be tipped up for loading purposes upon the application of sufficient upward manual force. The detent securely interlocks the barrel with the valve body closely adjacent to the point of gas transfer from the valve body into the barrel so as to minimize misalignment of the barrel and the valve body due to tolerance buildup and manufacturing inaccuracies. Sealing surfaces on the spring loaded arms of the detent assembly situated on opposite lateral sides of the barrel also serve to cover the gap between the end of the valve body and the barrel when the detent is closed so as to inhibit the escape of gas during a firing action and eliminate the need for elastomeric sealing O-rings. Cooperating cam structures on the breech end of the barrel and the jaws of the detent assembly cause the retaining jaws to be sufficiently opened and closed as to clear the barrel during its opening and closing action.
