SPECIFICATION forming part of Letters Patent No. 324,296, dated August l1l 1885.

Application filed March 5, 1885. (No model.)

To ail whom it may concern:

Be it known that we, JOHN M. BROWNING and MATTHEW S. BrtowNiNG, of Ogden City, in the county of Weber and Territory of Utah,

5 have invented a new and useful Improvementin Magazine-Guns; and we do hereby declare that the following is a full, clear, and exact description of the same.

Our invention relates to that class of breechio loading lire-arms in which the breech piece o1' bol t is arranged to move back and forth in an axial line with the bore of the barrel, and is operated by a finger-lever extending below the receiver' and forming the triggenguard.

The main part of the invention is adapted especially to magazine-guns, but is also applicable to single loaders. `In `connection#with this main part we have also Shown subordinate features, all as hereinafter fully explained. 2o lhe principal part of the arm is the device for locking the holt when the breech is closed,

the object of this being to provide an indestrnctible dead-lock for the bolt. The second feature consists of an improved construction of ejector. The third feature relates to the construction ol' the carrier. and the subordinate lialures are explained hereinafter.

ln the accompanying drawings, Figure l. Shows a central longitudinal vertical section 3o ofthe rceeiverand bolt of the arm with its ad jacent paris, and will; the working parts in side eleval ion, the ligure .showing the breech closed. Fig. 2 shows a like section with the workingl parts in side elevation and with the breech open. Fig. 3 isatop view of the reeeiver and holt with its adjacent parts. Fig. 4 isa plan view of the carrier. Fig. 5 is a sec tional cut on line .fc .1', looking from point 1, Fig. l. Fig. o is a side view with the wall of 4o the receiver taken away, showing the extractor and the improved carrier for cutting oil' the cartridges in the magazine or stopping the one next to the one coming into the carrier at any point desired. Fig. T is a delail plan view of the extractor shown in Fig.

In these drawings, the receiver A with its bottom plate, b, and the magazine c and barrel rl are shown in their usual relation to cach other. rlhe bolt li is arranged to be moved split end ofthe lever.

J is pivoted at k in the receiver.

longitudinally from the rear end of the barrel, 5o in order to open, and toward it to close, the breech. The bolt slides in guiding-grooves in the usual manner. The upper part of the bolt is Yehambered out to receive the locking-block f. This locking'piece, in connection with the 55 lever. locks the bolt in position to close the breech. The main part ofthe locking-piece is narrow, as shown in plan view, andfis enlarged at the forward end, the `chamber in the bolt being formed accurately to receive it. 6o The piece is pivoted at its rear end within the bolt by a pivot, g. The front end of the lock ing-piece is formed on a curve struck from this pivot g, and the front wall of the chamber in, the bolt has a corresponding curve, so that the locking-piece fits accurately against it when said piece is down in locking position.A The wide side of the forward end of the lockingf piece extends laterally below the bolt and tits accurately into a recess, fi, cut into the walls 7o of the receiver on the are of a circle struck from the saine pivot g. This recess in the walT extends down to or near to the lateral guidinglgrooves of the bolt, and when the locking piece is down the lateral wings or extensions of its forward end extend down near to thfs groove. The forward end of the locking-piece has sufficient upward movement to cause'the lateral extensions to clear the lateral recess.

The locking piece is pivoted to the lever J SQ by a pin, l. The lower part 4of the locking` piece is made thin, and extends between the The pin passes snugly through the end of the lever and through a slot in the locking-piece, this slot being long enough to provide for the necessary lost mo` tion in the operation of the paris. Thellevcr Its front end lits against the bolt on an arc. of a circle formed from the joint-piu k, and the rear of go the lever is also formed on an are ofthe circle f struck from the saine pin and bears against a coi-respondugly-shaped portion of the abutment of the bottom plate.

The .parts are so adjusted to cach other that as soon as the bolt is brought to itsseatin the breech the lateral extensions of the end of the locking-piece are in line with the recess i, and

further movement ol' the lever brings down the lockingpiece with these extensions in the recess i. At the same time the rounded bearings on the lever tit against theabutinent in the bolt and the bottom plate so that the bolt is securely locked in place by an indestructiblc lock.

In order to hold the breech closed, n spring may be applied in various ways. W'e have shown a convenient form in Fig. l, t'or which the locking-piece is bored longitudinally from the rear and a spring, n', inserted, the hole bcing stopped by a plug, r'. The front end of the spring bears against the bottom ot' the hole and the rear end against a pin, w. The pin passes through the bolt and through the locking-piece, the hole in the locking-piece being elongated to allow the necessary move ment ofthe lockingpicce. The elongated hole may be grooved and the arc of a crclestruek from the point y, and as the front end ot' the piece is raised the spring is compressed by the movement of the piece on the pin u', the spring thus having the etl'ect to hold the front end ot"` the locking-piece continually down, and with it the lever towhich it is connected.

The hammer m is arranged to strike the pin n, contained in the locking-piece, and adapted to slide with a. limited movement in said piece, with its front end projecting, when pressed forward, slightly beyond the front end ofthe piece. Nhen the locking-piece is down in position, which, as before explained, occurs whenthe breech is closed, the pin n is in line with the tiring-pin o in the front end of the bolt,and it is only when the parts are in this position, as shown in Fig. 1, that the blow of the hammer can be 'transmitted to the cartridge.

The bolt is adapted to be used with any ordinary extractorfor example, as that shown in Fig. l; but we have devised an improved form which we purpose to use with this gun. This form is shown in Figs. 6 and 7. The front end of the bolt is bored out to receive the shank a ofthe extractor. This bore is slightly inclined, the lower part being a. little forward of the upper part, which causes the extractor to hug more closely tothe shell when the bolt is drawn back.

,l .The hole fitted to the reduced end ot' the eycctorshank is preferably rst formed by boring a smaller hole, which is then enlarged trornboth ends, leaving a shoulder or rib, e.l The shank is formed with a slot, d', adapted to receive the tiring-pin and to permit the necessary vertical movement of the extractor. The extractor is drawn down by means of a spring, b', the upper ends of which rest against thc shoulder c and the lower against a nut, which gives it a proper tension.. 'The plan view, Fig. 7, shows the relation of the ejector und tiringpin.

' An ejector-piu, q, is set in the front end'of the bolt in an inclined position, and has suitable movement, so that it may advance bcyond the face ot' the locking-bolt, as shown in Fig. 2 Another pin,q', is placed in the tin gerlever in such position that when thelcvcr is thrown back the front end ot pin q will press against the rear end of the pin q. The latter pin is set in the bolt so as to projectt'rom its face to one side` of its center. The pin q" is provided with a spring, as at 5, which keeps it pressed outward against the pin in the bolt, and this pressure beingexertcd upon the shell or cartridge head near its edge will forec thc shell to one side and slightly under the overhanging flange ot' the receiver, and thus hold it down until the carrier begins to rise, the spring while exerting this pressure being slightly compressed. When this latter action takes place, the shell or cartridge will be drawn from under the side of the receiver and lifted up slightly. Thespring ejector-pin q" will then exert its whole force, and its rear end will also strike against the hammer, as

` shown in Fig. 2, and the shell will be thrown from the piece. During this action the shell is held in the usual manner by the entracte)- upon its upper edge.

Uur improved carrier is designed not only to clamp the cartridge, but also,in connection with the special construction of the beveled shoulder u upon the side of the bolt. it is de signed to stop the next cartridge in from ol' the one moving upon the carrier, and to prevent it from following the first upon the car; rier. Otherwise it would lock the carrier and prevent it from rising. Thisis liable to happen where a cartridge is used of too little length. The carrier is composed of two parts, r and s. These are pivoted to the receiver by two short screws passing through their rear ends. The rear ends also extend upward and have shoulders, as shown at c, these shonl ders being arranged to be struck by the shoulders c' on the forward end of the bolt in the usual manner. The sides are also provided with upwardly-extending wings 2, adapted to grip the cartridge when the sides are brought together. The rear end of the part .s also extends back and up, as shown at e, entering slightly into a recess in the under side of the bolt. This recess terminates at the front in a beveled shoulder, u, which is intermediate between the shoulder c' on the bolt and the projection c on the carrier. The shoulder a arts upon the projection o to elevate the carrier sufficiently to block the entrance thereto, and the shoulder c in the continued movement of the bolt acts upon the projection c to elevate the carrie;` andV cartridge carried thereby to the.bore of the gun. The distance between a and e is of course less than that between d and c, in order to give the successive movements to the carrier. A screw-pin, 3, passing through the side pieces diagonally,is made fast to the part s, and tits loosely into the part fr. The forward ends may be fitted to each other by inclined faces, as shown at i. The part r is slotted where it is pivoted to the receiver, as shown in Fig. 2. The upwardly extension on the part r is farther forward when the car- 5s andthe rier is down than the part x, so that when the bolt moves back it strikes the shoulder on the part r first, and the part x having no longitudinal movement on its pivot the part r is carricd back, and by reason of the inclination of the pin 3 the forward ends are brought together, clamping the cartridge on the carrier; but this clamp will be released as soon as the bolt begins to move forward.

In the operation of the gnmwhen lhebrcech bolt is drawn back the incline u is caused to strike against the rear upper end ofthe carrier, moving the forward end up slightly,so as to obstruct the passage of the next cartridge i5 upon the carrier. It is held in this position until the projection on the bolt strikes the pro jection on the carrier and throws the carrier up, bringing the cartridge into line with the bore ofthe gun.

'lhe operation of the gun is as follows: Suppose there is aeartridge in the barrel and the magazine is loaded and breech closed, the breech is opened by pressing the lever forward inthe usual manner. The first effect of this movement is toi-aise the front end ofthe lock` ing-piece and this unloeksthc'bolt. The lever through the locking-piece carries the bolt back, the extractor being engaged with the flange of the cartridge and drawing it back, 3o at the same time sliding back on the carrier from the magazine. The hammer has been forced back to full cockand caught by the trigger. Vhen near the limit of the backwa rd movement of the bolt,the shoulder on its front end strikes the upward extension of the part r ofthe carrier and slides said part backward,causing the carrier to grip the cartridge, holding it firmly. Further movement ofthe bolt causes it to strike the shoulder' on the 4o part s, and the whole carrier is raised till the forward end of the cartridge is in line with the bore of the barrel. At the same time the ejector-pins have come into line with each other, and are pressed forward by striking against the hammer, so that the forward pin is forced out, thus throwingr out the shell or cartridge. The movement of the lever being reversed,1't first opens the carrier by releas: ing the partr. Continued movement causes, 5o the bolt to for e thecartridge from the carrier into'the barrel, and then th-row down the carrien to receive nothercartridge from the magazine. Fiually,it draws the locking-piece into place. El'hisleaves the'tringpins inline,

sur .1s .ready .t0 fire. l It wil observed that the gun cannot be discharged 'untily the `breech is closed and `locked, as the pinsdo not come into line until the locking has been effected.
