As shown in the accompanying drawings, 1 is the barrel of the gun; the "fore end, so called; 3, the magazine into which the eartridges 16 are placed, and 12 is the stock oi the gun.

The magazineis made with two side chainbers and a central channel, above the upper part of which channel breechebolte is slidable,

and within the lower part and behind the cartridge-chamber 18 the guard and operatinglever 6 movable. The upper end ot' the level' 6 is pivoted to the breech-bolt #t near its front, andan equaliying-link 5 is pivoted to the front lower part ot' the magazine, and the opposite end, which is slotted, as shown, is pivoted to the lever at a pointintermediate between its ends.

8 is asafetiY locking-bolthaving'its rear end rl`he slotted connection between the link 5 and the lever 6 allows the lever (3 when iirst moved to open the breech to pulldown upon the link 7 and locking-bolt 8, so as to disengage the locking'diolt from the breech-block before the lever 6 conmiences to retract the breech-block. llhe pin which connects the lever (i with the link 5 slides in the slot in the link during' the iii-st portion of the downward movement oi' the lever and until the lockingbolt is disengaged from the breeclrbolt. At'- ter that, the pin in the lever (5 liaving moved to the front end ot' the slot in the link 5, the latter serves as a Jfulcrum about which the remainder ot' the downward movement Oi the lever is eliected and the breech-bolt is rctraeted.

9 is the hammer of the gun, which is force",I back against the tension of the mainsprii 23 by the rearward movement oi the breedbolt 4, the lower part-ot which engages the head of the hammer, as shown, and when fully retracted it is engaged by the sear of the trigger 10.

The firing-pin is made in sections c, extend* .ing iongitudinally tln'ongh the breech-bolt #i from the rear to the front end, and the rear end of this firing-pin is in line to be struck by the hammer when it falls, the front end being in suchposition as to strike and explode the fulminate of the cartridge when the latter is in the barrel of the gun. The tiring-pin channel is so located that itcrosses the lockingrecess 22 in the lower part of the breech-bolt, and when the safety-lock 8 is withdrawn from the breech-bolt by the opening of the breech mechanism there is no connection between the rear and front p'ortions of the firing-pin, which are permanently located in the breech-bolt, thus presenting no danger of explosion by accidentally striking the rear end of the tiring-pin. When the breech mechanism is closed and the locking-lug 8 of the lock-bolt 8 enters the slot or channel 22, it [ills this channel, and the section a. of the firing-pin which passes through this locking-lug is then brought into line with the parts a of the liring-pin which are in the breech-boltf Under these conditions the sections of the firing-pin are in line with each other, and when the hammer falls upon the rear' end the effect of the blow is communicated through the sections to expiode the cartridge.

The magazine is made, as previously described, with two cartridge-chambcrs 18, l0- cated upon opposite sides oir' the central channel,'witliin whichehannel the lever 6 is adapted to swing, so that the cartridges are out of iinewith the axis of the barrel when in place. At the bottom of each chamber is a carrier 14 and spring l5, upon which. the cartridges are adapted to rest, and the tendency of this spring is to raise them upwardly, so that as fast as the upper one is removed from either chamber the remainder' of the cartridges are raised, so that the upper one is constantly in position to be transferred to the barrel ci' lthe gun by the movement of the breech-action, and when thus transferred -the cartridge-shell lies in a position with the projectile Within the bore 19 of the gun. The spring 15 is secured at the front end by a bolt, as shown at 20, and upon its rear end is acartridge-carrier 14C, upon which the lowermost of the cartridges rest. the others standing, essentially, in avertical piane above the same. The springs 15 are 'movable in Vertical slots, as shown intransverse section. Upon the outer sides of these slots rare movabie racks 26, having teeth on their inner faces, and these are actuated by buttons 26a, which project slightly upon-each side of the magazine, so that they may 'be pressed inwardly by the thumb and finger' of the operator.

This movement forces the toothed inner faces of the catches into line with t ie carriersprings, so that as the cartridges are placed in the chambers and each one presses the next one down the carrier-springs will enthe rackplates,and will thus be prevented from immediately forcing the cartridges out again. VJ hen the magazines are thus filled, the cartridge eut-eti' 13 may be turned so as to prevent any transfer of the cartridges from either of the chambers of the magazine to the barrel of the gun. Under these -conditions single cartridges may be inserted l Whenever the springs, as at 13b.

breech-bolt is retracted and impellcd into the barrel by its forward movement. The tops of the magazine-chamber are closed, shown in transverse section, and the intermediate eenw tral portion is normally closed by the closing of the breech-bolt. Vvlhcn the breech-bolt retracted and the cutoii is turned so as to re lease the cartridges :from one side et' the magazine, they Will be transferred into the barrel by each reciprocation or' the breech-bolt. The cut-oli consists of a turnable milled header thumb-piece, and this carries an irregulariyshaped cam 13. l

13 represents plates pivoted to the front of the breech-bolt and pressed outwardly by Pi ns i3 project upward 5y from the plates 13a and enter the groove of vthe cam. rlhis groove is so shaped that by turning the cam to a certain position both plates 13 will be drawn inward, so as not to project from the sides of the breech-bolt, and when thus retained the bolt may be reciprocated without moving the cartridges from their respective magazine-chain bers. By turning the cam a part of a revolution the pin i3" of one of theplates 13 moves into the wider curve of the cam-groove and the plate may be pressed outward by its spring 13, so that the forward end of the plate wiil he projected into the corresprnding magazine-chamberbe hind a cartridge when the breech-bolt is withdrawn` and When the ibolt is moved forward the plate will engage the uppermost cartridge in the chamber and advance and transfer it toV the barrel, no action taking place in the other magazine. N hen one receiver is exhausted, the cam may be turned a l1alt-r wolution, and this will release'the plate 13 upon the side of the full magazine and retract the opposite one.

To load the arm, the cut-oti 13 is set, as shown, toA release 13, (right.) 13 springpressed, as shown., and as the breech-bolt is withdrawn i3 springs inward until the head of top cartridge is passed. lhen it springs outward and engages in rear or'. head of cartridge and pushes it into the chamber in barrei. This can be released until the right magazine is empty. Then by turning i3 halt-round 15 (left) is released and 13 (right) is closed, and by turning one quarter-round i3(right} 13 (left) are closed and the gun can be used as la single loader. To lill the magazinmthc breechbolt is withdrawn and the carrier ,11i pushed down by the finger, the other hand pressing in one or both knobs onthe toothed racks at the front of the receiver. These racks eng: e the carrier-springs and keep them from push'- ing upward while filling the magazine. A slight pressure on each cartridge,willdepress these springs, and they can be released when the magazines are full by withdrawing pressure from the knobs ci' the toothed racks. The tops or' the magazines are closed, and the cartridges are prevented from rolling out into the magazine by the-curved spring i7, which IOO ILO

ts over the top cartridge and which is raised as the cartridge ispressed from the magazine into thebarrel.

The pieces 13 have a slight projection or bevel outward at fl in front et' the breech-bolt. They fit in suitable slots on each side et the rear ot' the cartridge-chamber. These projections are so beveled that when the parts 13 are projected outward they will stand straight across and properly engage the cartridges to move them forward.

At the rear of each magazine is a suitablycurved end against which the cartridges slide, and to keep them in line v'ith the are described by the carrier-spring the cartridge-heads slide in suitable grooves in the side walls of the magazines. This keeps them in line and prevents any jamming or wedging.

The lextractor 3() is shaped approximately shown in the drawings, and the front end is hook-shaped'andadapted to engage the fiange of the cartridge-head when the latter has been forced into the cartridge-chamber, and when the breech-bolt is again withdrawn this extractor acts to draw the cartridge out of the chamber.

`The ejector is shown at 27 and is a spring. It is of bell-crank shape pivotcd at the angle, with one arm extending' under the lower edge of the cartridge-head, so that while the other is caught by the lever when opening the gun a tension is placed upon the spring, and this, in conjunction with the extractor, acts to throw the cartridge-shell upward and backward and out of the chamber.

The cartridges are guided from their chambers at each side by the convergently-curved front endsof the outer sides of the magazine, as at 3b, and by means of a centrally-pivotcd spring-guide, as at Q8, having' an upwardlyprojecting tin, the cartridges from either magazine are prevented from being forced too far toward the opposite side to enter the cartridge-chamber on that side of the gun.

The lever is held in place and prevented from falling downward when the gun is closed by the spring-pressed catch` at 50, which lits in 'a suitable opening at 50.
