hook swinging on a pin passing transversely throughthe recoil-block near its face. Ejection.—By the action of a spiral spring set in the face of the boltand pressing against the lower edge of the cartridge-head until the shellis clear of the chamber. The shell being then free to turn, is rotatedaround the hook by which it is held and is thrown clear of the gun. A safety-lever is connected with this arm and serves to dispense withthe necessity of a half-cock notch; a projection on its under surfacepasses through the guard-strap in rear of the bow, and before firing, isto be pressed upward with the outside fingers of the hand, so as to lib-erate its forward end from its position behind the trigger, which untilthis has been done is immovably locked. The accidental opening of the breech may be prevented by turningup the handle part way and pressing down its stop-pin; the point ofthis passes into a hole in the side of the recoil-block, and thus preventsthe revolution of the entire bolt.
