TRABUE MAGAZINE GUN
The receiver of this gun is bored through longitudinally for the breech-bolt in line with the barrel, and also below the barrel, in line with the magazine, which is in the tip-stock. It is also cut away at the side, forming at the rear a shoulder for locking the bolt, and at the same time an opening for inserting the cartridges into the chamber or magazine, and also for ejecting the empty shells.
The bolt is composed of three principal parts, viz., the body or locking-tube; the cocking-piece or hammer, into which the firing-pin is screwed, and the bolt head, which carries the extractor. An arm of the latter is pivoted in a slot in the bolt-head; a small spiral spring bearing on the arm above the pivot causes the hook of the extractor to descend after it has passed over the head of the cartridge. The front part of the firing-pin passes through the spiral spring and through the extractor-arm. On the rear of the locking-tube is a small projection, which enters a corresponding notch in the front face of the hammer. When the bolt is unlocked, the projection, riding out of the notch, cams the hammer to the rear, withdrawing the point of the firing-pin within the face of the bolt.
The magazine is loaded through the receiver. The cartridges descend an inclined arm, on the inner side of the guard, when a finger on the underside of the bolt-head forces them into the magazine. They are prevented from escaping the latter by a spring-stop, which is pivoted to the left side of the receiver and operated by a push-button. The lower end of the stop springs through an opening in the side of the receiver just in front of the mouth of the magazine. When the piece is to be used as a magazine gun, the push-button of the magazine-stop is pushed to the front, the first cartridge under the pressure of the magazine-spring backs up the inclined arm of the guard until its head is checked by a notch in the receiver. If the bolt then be closed, the finger of its head runs under the cartridge and raises its front, when the bolt forces the cartridge into the chamber.
When the piece is to be used as a single loader, which can only be done when the magazine is empty, the cartridge-follower runs out from the magazine and forms a floor, so to speak, to the receiver, so that the cartridge, on being inserted into the receiver, is in line with the barrel. The closing of the bolt then forces it into the chamber.
