IMPRQVMENT IN MAGAZINE-GUNS.

Specication forming part of Letters Patent No. 129,523, dated July 16, 1872.

Specification describing an Improvement in Magazine Fire-Arms, invented by ANDREW BURGEss, of -Qwego, in the county of Tioga and State of New York.

Figure 1 is a vertical longitudinal section of the bed-piece, showing the position of the opening in which the working mechanism of the gun is placed. Fig. 2 is a sectional elevation of the bed-piece and working mechanism when the breech is closed. Fig. 3 is an elevation of the bed-piece, its contained mechanism being shown in dotted lines, with the breech-block open or thrown back. Fig. 4 is a side view of the carrier-block and one of the hands for' holdin g the cartridge in place. Fig. 5 shows one `of the cartridge-extractors, and Fig. 6 a mod iication of the same. Fig. 7 is a plan or top view of the breechblock.

In bot-h sides of the interior of the opening of the bed-piece are the groovesa b, the longitudinal one a extending the whole length of the opening and into the end of the barrel, the vertical groove b extending from the other downward, at a right angle, to the bottom ot' the bed-piece. The breech-block A at the rear end turns downward, and its further continuation forms the lever'guard c, by which it is operated. Said block has pins or projections at e working in the grooves a b, thus serving as guides to control its movements when it is operated by the lever-guard c. On the projecting pins of the breech-block are hung the extractors f, (shown in dotted lines, Fig. 2,) the points of which pass before or spring over the iiange of the cartridge when the breech is closed.' The cap C is connected with the breech-block by the link D, which is pivoted to said breech-block near the forward end, the rear end being secured to the cap. The cartridge-carrier has vertical slots, into which are fitted the hands g. These project a little from the carrier-block and run inthe corresponding grooves h of the bed-piece.

The magazine is secured under the barrel, and is furnished with a spiral spring in the ordinary manner.

To operate this arm, the magazine is filled by inserting the cartridges through the open' ing in the side of the bed-piece. The leverguard is then pushed forward. This brings down the rear of the breech-block, and the pins e, following the grooves a b, give the forward end of this block a backward motion, which is communicated to the sliding cap C by the link D, and this cap cocks the arm by its rear end operating again st the hammer and pushing it back. The cartridge-shell is at the same time withdrawn by the extractors f, and the cartridge-carrier, being no longer confined by the breech -block, rises by force of the spiral spring F, and, carrying up a cartridge, throws out the withdrawn shell; and the hands g close inward at the top by their upper projecting parts striking the shoulders i, formed by the termination of grooves h, and thus hold the feeding cartridge from flying out. The leverguard is now pulled back, which closes the breech, the breech-block driving the cartridge before it into the bore of the gun, and also forcing down the cartridge-carrier E; and the hands g are opened by their lower ends striking the shoulder t', left by the lower termination of the grooves h, so as to admit a new cartridge.

When used as a single loader the breech is opened, as before, by the lever-guard, and the cartridge dropped in at the top'by hand.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is j l. In a breech-loading iire-arin, a breech block, A, provided with projections e adapted to work in grooves in a bed-piece, substantially as specified, so that said breech-block may have a vertical movement at its rear end and a longitudinal movement at the front end when opening and closing the breech.

2. In a breech-loading fire-arm, a bed-piece provided with the grooves b and t' running at right angles to each other, and adapted to guide and control a breech-block, as and for the purpose specified.

3. The construction and arrangement of the .extractors f, grooves c', breech-block A, and

front projections e of the same, all as shown and described, whereby the said projections serve as the pivot-guides on which the breechblock turns, and as impelling devices for the extractors, as 'set forth.

4. Combination of the hammer, cap C, link D, breech-block A, and guard c, when operating, as described, for the purpose of cocking the arm, as set forth.
