LEWIS-RICE MAGAZINE GUN
This gun belongs to that system in which a fixed chamber is closed by a movable breech-block rotating about a horizontal axis at right angles to and below the axis of the barrel and in front The cam is held in position by a spring, one branch of which serves as a trigger-spring. The breech-block is simply a box containing the firing-pin, a bell crank lever, one arm of which controls the motion of the firing-pin, the mainspring, trigger-spring, etc. The box is closed by a cover in a slot in which is situated the extractor. In operating the lever, so as to open the block, a point bears against the surface of the cam, presses it forward, and unlocks the piece. During the unlocking, the lower arm of the firing-pin lever is so moved by the nose of the cocking-lever as to cause the upper arm to retract the firing-pin. When the lever has been rotated sufficiently, the trigger-spring causes the nose of the trigger to enter the full-cock notch; at the same time the shoulder of the cam rides over the point of the trigger. The piece cannot then be fired until the cam is in its seat. The extractor is a flat blade, turning on the same axis as the lever, and operated by the shoulders of the slot in the cover of the breech-block in which it lies. The magazine is in the butt-stock. It is loaded at the side, near the rear.
