To all whom, it 71mg/ concern:

*ie it known that I, EMMANUEL Anonno SATA2-iron, oi' the UnitedStates Navy, and a citizen ot the Republic ot France, have iuventedl certain new and useful Improvements in Magazine-Guns; and I do hereby declare the-following to be a full, clear, and exact description ot' the invention, sueltas will enable others skilled in the art to which it appertains vto make and use the same.

The object of the invention is to produce a [ire-arm adapted for very rapid tiring, and for being,r ted directly from a magazine supported on a belt worn by the person using the weapon; and it consists in the constructions hereinafter described, and particularly pointed ont in t-he claims.

In the accompanying drawings, which form apart ot' this speeilieation, Figure vI, represeuts a sectional view showing the several parts ol' the gun in position for vtiring. Fig. 2 is an enlarged section showing the position of the parts with a cartridge in the cylinder ready to be inserted in the barrel of the gun.

Fig. 3 is a detail plan view' with parts broken away. Fig. I is a cross-section of the eartridge-eylindcr on the lille .r x, Fig. l. Fig. Tris a perspective view ot the same, showing the position ofthe cartridge-carrying ribhon. Figs. t; and 7 are detail views ofthe portable magazine. Fig. S is a detail view of the operating-levcr. Figs. 9 and Si are detail views ot' the vertical sliding.,r block and the `breechblock; Fig. 10,21 detail view ol' the mechanism for revolving;` the cartridgeeylindcr. Fig. Il is a view of the knife forsevering the ribbon. Fig. I2 is a side view showing the knife in positiohriu the eartridge-oylinder, and Fig; 13 is a side view ot' the cartridge.

illagnzine-guns as heretofore constructed t'or use as a firearm to beheld tothe shoulder ot' the person using` it have had their niagazines formed in the stock or some other part ol' the `gun, which has made them very nn- \v{'/e.lly on account olf the additional weight a( ded tio the arm by thcloaded eartridgesm-ml has had the ot'l'ect ol' taxing the strengthol' the user t/o hold thc fire-arm in position t'orexecntiene" y niyiuvention the magazine is supported by belts abontthe body and crossing' the shoulder ot' the person and the iirearm relieved of T all weight ofthe ammunition save that of the one cartridge iu the gnu and the few Sus- 1 pended upon the ribbon between the gun and the magazine.

Another impediment to tiring a great number of cartridges in rapid Succession has been the heating `of the b arrel to such an extent as to require the. firing to be stopped and time allowed for the parts to cool. To overcome this objection I provide a chamber around the barrel of thegun, which is in communication with a reservoir in the stock ofthe gun coutaining a cooling-liquid.

In ,most or ncarl y all ot' thc fire-arms now in usel the sight ot' the gunner is obstructed by hammers rojecting above the upper surface ot' the gun. To avoid this I locate the hamnicr within the ln'eech-block and present a smooth and unobstructed surface tothe eye ot' the gunner.

In the drawings, A represents a cartridgecarrying cylinder provided with five chainbers, a, adapted to reoei ve and hold a cartridge while, it is being` pushed into the barrel of the gun by the movable breech-block B. The eartridge-cylinder revolves upon anaxle, 0,'which is eccentricto the barrel ot' the gun, and the in# ner cud ot' the cylinder is provided with gear-A ing b, which engages with a pinion, d, the teeth of said gearing being` proportioned, one on the pinion to three on the cylinder. lThe pinion d 'is attached toa shalt, c, which hasits bearings in supportsfm and is provided with a worin-gear, ll, and a sleeve, t', which has a corresponding nut, j, t'ormcd in one end, and

a spider, 7;, in the nl posite end, through which the shalt c passes.

Upon thcslcevc 'L' is a sliding collar, Z, provided with a projecting pin, m, :1nd a conical bearing, n, which corresponds with the Seat 0 on the sleeve t', and is operated by the lever D (which .is indirectly attached to thc breechblock il) by means ol' a curved slot, 1);. with which the pin m engages, and l y which the cnrtridge-cylinder is rcvolvcd upon the forward stroke ot' said lever. To prevent the possibility ot' the cylinder A revolving.;` in the opposite direction when the lever I) is returned to its rear position, as shown inI Fig. 1,21. ratchet, q, and pawl r are provided, the pawl IOO .'being held in contact with the ratchet by been exploded. An arm, 7, attached to the.

spring s. The lever D is bent laterally, as shown in Fig. 8, to prevent interfering with the trigger 9, and the conduit leading from the reservoir is pivotedat u, and is provided with a guard, t, in the rear thereof and has avslot, a, formed in the arms w w, whiehengage with apin, f1`, projecting on both sides of the sliding block z, which has a dovetail projection, a', formed on the end thereof, which engages with a corresponding slot or seat, b', in the end of the breech-block B.

To prevent the breech-block B from heilig 'slots in the arms w w, and the arm c' of the sliding block z .is held in position by a spring, d', bearing upon the outer end thereof:

A spring, e,'is coiled around one end ofthe breech-block, -and when compressed is contained in a chamber, f', formed in the metal which constitutes the rear wall of the cartridge-chamber, and assists in throwing the lever D forward and extracting the discharged cartridge from the barrel by pressing upon the inner face of the sliding block z.

The breech-block is made in two parts, 1 2, connectedby an ordinary screw-thread, and the part 2 is provided with a chamber, 3, Within which there is a spring-actuated hammer, 4, and a tiring-pin, 5, provided with a,

spring, 6,' which serves as a cushion to the blow of the hammer, and also returns the pinV to its normal positiony after the cartridge has hammer 4, engages with a pivotcd latch l8, on the front end of the trigger 9, and hol s the hammer in position with the spring 10 con- 'tracted, ready for usc. A cam. 11, befaring upon the spring 12, securely locks the trigger 9 and prevents aniT accidental discharge of the cartridge. The arm 7 and the latch 8 are held ina locked position at all times when the cartridge is in the barrel ot' the gun by the spring l2 bearing upon the trigger 9. The .projecting cud of said trigger extends into thctingerslot of the lever D, for convenience of o'pcrat'- ing it.

E represents a knife attached to the sliding breech-block B by a bolt, y', and is pushed into the slots h in the walls of the chambers i, formed in the cartridge-cylinder A, and cuts oii the end ofthe ribbon from which the cartridge has been removed by the breech-b`lock` and forced into the barrel ofthe gun; The construction of the knife is,distinctly shown in Fig. 11, and by reference to Figs. 4 and 5 it will readily be seen that the slots h are cut at an angle to the periphery ot the cartridgecylinder, to accommodate the reciprocating motion of the knife and the position which it sustains to the axis of said cylinder.

Secured to the front end of the breech-block is an extractor, 13, which engages with the flange of the cartridge' and is held in contact therewith by a leaf-spring, 14, and is disengaged therefrom upon the back-stroke of the breech-block by striking the wall of the cartridgeA chamber or stock oli' the gun at 15.

The gun is made in three parts--namely, the barrel F, which may be smooth or rided, the casing G, and the stock H-thc several parts being secured ,together by screw-threads anda plate, k', hinged to the casing G at t and connected to the stock by a screw, mi. The casing may extend along the under side of the barrel to the end thereof.

Upon the inner end of the lower side ofthe Casing G is formed a screw-threaded extension. n', which engages with a corresponding screwthreaded socket, o', in the stoel: H, and the barrel F is supported by a block, p', which forms the outer end Walls ofa cooling-chamber` I, which communicates with a reservoir, J, in the stock H, containing a suitable cooling-liquid, by means of a passage, q', in the extension n', a conduit, i", and a pump, s', provided with the ,usualsupply or suction pipe and cheekvalves. i

The pump s is operated by a jointed lever. t', which is supported in guideways formed on the reservoir, and projects through the slot n in the upper edge of the stock H, and the tooling-chamber l is provided with :i reliefvalve, o.

By iilling the chamber I with liquid from the reservoir J the inner end ofthe barrel is kept cool, the parts prevented from becoming overheated, and as a consequence avery large nu nibeir'of rounds of cartridges may be tired in rapid succession without danger lof premature explosions of the ammunition prodneed'by the overheating ofthe metal, as frequently occurs in the ordinary magazineguns, or when they become too hot -i'or use with safety they must be laidaside to cool. After the chamber l has been filled the handle or lever t is folded down into the slot, as shown in dotted lines in Fig. '1. v K represents the cartridge-magazine, which consists of a box having a hinged cover, in which the cartridges, secured to a ribbon und wound in concentric layers about atthimble,

(not shown :i1-placed around a-eent ral sh aft, x', and Withdrawn through the opening tr',

taken to the gun, and a cartridge placed in one X of the chambersa of the revolving cylinder A, after which they are fed to the cylinder automatically by the manipulation of the lever D, as will hereinafter more fully be described,

The magazine is provided with a stud, y'. projecting from one side, and having grooves c formed in its sides to engage with the flanges a on the support b, attached to the liorigontal belt c at d", and to the vertical belt e" ntf, and slides freely therein. It is also providpd with a foot-piece, i", adapted to rest npon tile left leg of the gunner when in a kneeling position, to support the weight of the magazine and allow it to slid'e freely in the guideway formed in the support b, attached to the belts. To in sert the cartridges the cover g of the maga zinc is swung open on its hinge h, and the coil of ribbon with thev cartridges attached is placed in the box around' the central shaft, with one end projecting, as shown in Fig. (i.

Y The box is then closed, and the cover secured' by a hasp, j, when it is ready for use.

To secure the cartridges L to the ribbon M they are provided with a spring-prong, k", l'ormed integral therewith and connected near the t'ront end o't the cartridge, as shown in Fig. 13. The pro'ng` k is inserted through the ribbon from the under side atA a right an-` gle to the length thereof Yand the cartridges placed equidistant, as showlrin Figs. 2, 5, 6,/k

and 7, and removed therefrom by the tbrward motion of the breech-block B as it moves the cartridge from one of the chambers a of the cylinder A into the barrel ofthe gun, and the prong 7;" is returned to the wall of the eartridge, so as to t'orm a smooth surface.

The magazine K is designed to be, worn upon the lett breast of the person using' the tirearm, and the eartridgeon the end ot' the ribbon placed in one ot' the chambers ot' the cartridgecylinder, and a conti nnous snpplylkept up until all of the cartridges on the ribbon M have been used, when another coil of ribbon and fixed cartridges is placed in the magazine and thc lil-ing continued.-

lhe'several parts being constructed substantially as described, the operation is as follows; The magazine K having 'been filled wtha coil ot' ribbon with the eartidges atiired thereto and attached to the left side of the gunnenthe lever D is thrown forward and the breechblock l willn'lrawn from the cartridge-cylinder, the cartridge on the outer'end ot' the ri'obon is then placed in one ofthe chambers a ot' the cartridge-cylinder A, as shown in Fig; 2. The lever'D is then returned, the cartridge moved from the cylinder by the advancing;` breech-block B and seated in the end of the barrel of the gun` with the extractor 13 en- `raged with the rim or tlange on thc carltridge, the hammer 4 set, and the springI e' around the breech-block compressed in the chamber f'. The cam 1l is then moved into the posit-ion shown in dotted lines in Fig. l, and all ol' the parts assume their relative positions shown in said tigure. The trigger-9 is then raised, which releases the arm 7 trom the latch S. and the springl 1l) throws the hammer L lbrward, which strikes the firingpin 5 and explodes the cartridge in the barrel ol'the gun. The lever l) is-then thrown l'orward, and byits movement itrtirst extractstln discharged cartridge and places it in one ol' the chambers mot' the cylinder A. By this time the lcver D will have carried the collar l on the sleeve-z' against the bearingl or scat o,and the further movement ot'v the lever will canse the nntj to engage with the wornrgear h and turn the pinion (l onethirdl) ol'a revolution` which will turn the cylinder-A one-tth (l) ot` a revolution and carlv the discharged cartridge to the right and place a .t'reslrcartridge in the next chamber a, ready lo be inserted in .the barrel of the gan. The return movement ot' the lever D now pushes the cartridge out ot' the cylindcrA into' the barrel, and si multane ously therewith the arm. 7 4of the hammer 4 l engages with the latch 8, compressesthe spring 10, and sets vthe hammer ready for the next tiring of a mrrtridge, and the knife E is moved forward into the slot 7i and cuts otf the end 'ot' the ribbon from'which the 11n-nier cartridge had been removed. lt will be observed that bythe forward motion ot' the lever D the discharged `rcartridge is witht'lrawn t'rom the, barl',plaec`d iirth' revolving cylinder` moved another chamber a ot' the cylinder A in. line with the barrel, and the return motion moves the breech-block forward. inserts the cartridge, compresses the spring` c around the hlock,and cuts oitl the free end ot' the ribbon.

In the description otthe operation, it is to be presumed -that previously to commencing` work with the gun the cooling-chal'nber l has been titled with liquid from the reservoir J, and that during thel use ofthe gun the supply of liquid is kept up yby the pump as the necessities ofthe case demand.

In applications Nos. 193,779 and l193,780, led March 2, which are divisions ot' this application), -have claimed t he cartridge and the cartridge-box.A
