ber of cartridges and convey them in suc-` cession to the firing-chamber of the gun. This purpose I accomplish by means of the mechanism shown in the accompanying drawings,

Fig. l0 is a vertical longitudinal section in the axis of the gun-barrel, showing the breech-block raised, also showing the relative positions of the extractor Z1 and the locking-bolt U.

Similar letters refer to similar parts in all the drawings.

The stock A, the barrel R, the breech-pin R3, the hinged breech-block B, the receiver R2, the extractor b, and the firing-pin b2 I do not claim as new, as the same have been heretofore used. The cartridge-magazine .I consists of an annular receptacle having an outer and an inner shell, the space between these shells being such as easily to admit a number of cartridges C,disposed as shown in Fig. 2. The inner shell of the magazine conforms to the under side of thc stock. The ends of the magazine are closed, as shown in Figs. l and 3. The upper edges of the inner shell rest upon and the magazine is Asupported in place by lugs (Z, suitably secured to the sides of the breech R3. Running around the sides of both the inner and the outer shell, near the rear end of the magazine, is spun in the metal of the shell a corrugat-ion concave on the inside to receive the rim of the cartridge and near the other end a corrugation convex on the inside to support the end of the cartridge.

The magazine maybe made of any suitable light and elastic metal, and its structure is such that its sides may be sprung slightly apart when attaching or detaehing the magazine, as I will hereinafter explain. Inside the magazine and behind the cartridges is a coiled spring P, which serves to push the cartridges successively to the opening at the higher side of the magazine. At the upper side of the magazine is a door O, hinged at o and having' attached to it a linger M, conforming to the outer shell of the magazine, passing through a slot in the out-er shell and serving, as the door O is raised, to separate the top cartridge C from the succeeding one and to push it from the magazine into the cartridge-chamber R2. Vhen the breech-block B is shut down, a projecting lug b3 on the side of the breech-block impinges against the door O to close it and keeps it shut until the breech-block B is again raised. After the breech-block is raised and until after the empty shell is ejected by the extractor b the door O is locked by the projecting upper end t of the locking-bolt U. The other end t of this bolt passes through a transverse hole into the receiving-chamber R2, so that immediately after the extractor Z9 has ejected the empty shell the lower end of the extractor b will engage with the inwardly-projecting end t of the locking-bolt U, so as to move that end of the bolt U slightly back- Wardand upward, causing the opposite end of the bolt to move downward, thereby unlocking the door O and permitting it rto rise with the pressure from behind. When the breech-block B is closed, it presses down the end t of the level' U and restores the lever to its locking position. The rear end K of the IOO magazine abuts against the shoulder 7c at the front end of the trigger-guard K2. On the upper and inside edge of the end K is a pin k, iitting in a hole in the guard-plate k. rlhe shoulder 7c and the pin 7s serve to guide the magazine while being attached and to steady it when in place. On the right-hand side of the breech R3 is secured the shell L, which incloses the mechanism by means of which the cartridge is inserted in the end of the barrel R.

Fig. 3 shows a section through the shell and a sdeview of part of the mechanism. I will now describe that mechanism. A vertical camwheel p is secured to the end of the rod d. This rod is secured in a transverse hole through the breech-block B and turns in suitable bearings on the side of the breech. By this means the cam p is rigidly connected with the breech-block B and revolves with it., as indicated by arrows. A lower vertical cam E, supported on a transverse shaft c, engages with and is turned by the cam p until the point o of the cam p stops against the shoulder sot` the cam-wheel E. The lower part of the cam E is a segment of a cog-wheel meshing with a pinion l?, secured to one end of the transverse shaft j'. To the other end of the shaft f is secured the cog-wheel F, which meshes with a cog-pinion II, which meshes with the rack I, which slides in a suitable channel under the breech. At the rear end of the rack I is secured a vertical linger S, having an L-shaped top projecting upward into the cartridge-receiver R2 and moving backward and forward in a slot 32th rough the bottom of the receiver R2. \Vhen the breechblock B is fully raised, the linger S, propelled backward by the cam-gear which I have dcscribed, will rest near the rear end of the receiver R2, so as to lie behind the end of the cartridge when the cartridge is inserted. As the breech-block is turned downward it gives a forward motion to the rack l by means of the gear already described, and the finger S pushes the cartridge into the end of the barrel R. \Vhen the breech is closed, the rim of the cartridge lies in the recess between the front end of the breech-block and the extractor b, so that after the discharge the empty shell may be ejectedby the extractor in a manner well known. The magazin e-door is locked for the time that is occupied by the breechblock in turning from the closed to the wideopen position, and the empty shell is discharged by the extractor l) before the door of the magazine is opened. In raising the breechblock B the rack I is caused to move backward and the finger S is left in position to engage with and carry forward the next cartridge, and so on.

The operation of my devices is as follows: To attach the magazine J, it is grasped with one hand, the gun being held with the other, and is moved backward along the under side of the stock until the rear end of the magazine abuts against the shoulder k. The magazine is then pushed upward, its sides springing apart until the upper edges of the magazine slip over and rest upon the lugs d. Simultaneously the pin 7c enters a suitable hole in the guard-plate and prevents the magazine from slipping forward. To detach the magazine, its sides are sprung apart and itis pulled downward. To load the gun, the breech-block B is raised, causing the rack I to travel backward and stop in the position indicated by dotted lines in Fig. 1. The cartridge is then dropped into the receiver R2. The upwardly-projecting finger S then stands behind the rim of the cartridge as it lies in the receiver. The breech-block B is then turned down, imparting a forward motion to the rack I, causing the connected finger S to push the cartridge forward until it comes within the arc of the point b4 of the breech-block B, which as it turns downward pushes the cartridge into the barrel R. The cartridge is then iiredin the usual manner. To discharge the empty shell, the breech-block is raised until its edge strikes the projecting lug on top of the extractor h, throwing the extractor over the center, so that the spring behind it acts, giving a quick backward and upward motion to the lower end of the extractor b, which catches on the rim of the cartridgeshell and throws it out. At the close of the operation I have just described the breechblock B rests in the position indicated in Fig. l0. Immediately after the empty shell has been ejected the rear edge of the extractor b engages with and operates the bolt U to unlock the door O, as I have heretofore described. 'lhe door O being unlocked, the pressure of the springPbehind the cartridges pushes them around until the upper cartridge falls into the receiver R2. Then the door O is open, the linger M rests between the upper and the next cartridge, so that not morethan one cartridge can fall into the receiver R2 at the same time. The breech-block is then turned down, in its descent closing the door O, moving the bolt U to lock the door O, and giving forward motion to the rack, pushing the cartridge into the barrel, as I have already described.

I do not claim an annular detachable magazine, broadly, as detachable magazines of various forms are in common use, but restrict myself to a magazine of elastic material having sides adapted to spring apart for the convenient attachment of the magazine tothe firearm, the resilient power of the material of which said magazineis made serving to retain the magazine in position on suitable supports on the firearm.
