. 1 SPECIFICATION formingpart of Letters Patent No. 487,659, dated December 6, 1892. Application filed March 7, 1892- Serial No. 423,999. (No model.) I

To all whom it may concern:

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

5 have invented a new Improvement in Magazine-Firearms; and we do hereby declare the following, when taken in connection with accompanying drawings and theletters and tigures of reference marked thereon, to be a full,

clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in-

This invention relates to an improvement in that class of firearms in which the breech is opened by a forward sliding movement of 5c the barrel,and,while the invention is specially adapted to magazine-firearms, it is also applicable to sin gle-loaders, the object of the invention being the construction of an arm ,,which may be readily operated from the shoulder for rapid firing.

The invention consists in the construction and combination of mechanism, as hereinafter described, and particularly recited in the the claims. I 6

A represents the receiver, to the forward end of which the barrel B is attached in the usual manner and so as to open into the receiver at the rear.

C represents a magazine arranged beneath 6 the barrel, also opening into the receiver atthe rear.

Instead of the receiver being attached directly to the stock, as in the more general construction of firearms, the receiver is detached 71 from the stock, and so that the receiver, with the barrel, may be drawn forward from the position seen in Fig.1 to that seen in Fig. 3 and returned. The forward end of the stock D is provided with a plate E, against which 7 the rear end of the receiver may abut, as seen in Fig. 4, when the receiver is in the rear position.

The receiver is constructed with a spindle F, projecting from its rear end and dow n- 8 wardly inclined according to the downward inclination of the stock. This spindle is made tubular, and within the stock is a tube G, opening through the plate E at the forward end-and corresponding to the spindle F, and 8 so that the spindle F may slide longitudinally therein as a guide for the forward and back movement of the receiver and barrel. I

H represents the breech-piece, which is arranged longitudinally in the receiver and so 9 as to be free longitudinally; but the breechpiece H stands between the two sides of the receiver, and so as to allow the receiver .to move forward and back to take the barrel away from the forward end of the breech- 9 piece. From the plate E is an upwardly and forwardly projecting arm I, which is constructed with an upwardly and forwardly ini-piece and the slot J in the arm I is a ,which forms a connection between the i-piece and the arm I, so that the slot the forward-and-back movement of the l-piece. In the normal or closed posi- 1e pin K stands at the lower end of the and so that a forward movement iml to the breech-piece will cause the pin ide forward and upward. in the slot J,"

as to raise the rear end of the breechas it is thus moved forward and as-from sition seen in Fig. 3 to that. seen in he receiver, beiow the breech-pi ce, a ler L is formed. This appears in Fig. 3

forward end of the spindle, and the i-piece is constructed with a correspon doulder M, and so that when the breechis in the closed position, as seen in Figs. 3, the shoulder of the breech-piece abuts at the shoulder L of the receiver, and so he breech-piece is locked in its closed )1], so as to resist recoil.

barrel is provided with any suitable a by which it may be moved forward ickward. (Not shown.) The stock beld and the barrel moved forward, the er, spindle, and breech -piece will all together, because the shoulder L enthe shoulder M of the breech-piece; but forward movement of the breech-piece ,1 end will rise, because of the moveif the pin K in the slot J, as before de- 1, and so as to take the shoulder M of eech-piece above the shoulder Let the ar by the time the pin K has reached per end of the slot in the arm J, and so.

he breech-piece being there arrested, oulder L of the receiver may. pass forieaving the breech-piece stationary and s rear end in the raised position, the id of the breech-piece resting upon the side of the spindle, as seen in Fig. 6. the barrel is returned, the breechtill remains with its rear end in the ition and rides upon the upper side of ndle until the receiver has returned so to take the shoulder L to the rear of wider M of the breech-piece. Then as trrel or forward end of the receiver the forward end of the breech-piece force the breech-piece rearward, and rend will be drawn down because of :lination of the slot J until the shoulhas passed down forward of the shoul- )f the receiver in the fully-closed po- )f the breech-piece, and so as to lock eech -piece in that closed position :recoil. The breech-piece fits closely n the sides of the receiver and upon at I, so that that connection between tech-piece, the stock, and the receiver ts the receiver and stock against any tendency to. turn laterally upon the spindle as an axis. The breech-piece is provided at its forward end with extracting-hooks to engage the head of the cartridge-shell, so as to withdraw it when the breech is opened. The receiver has an opening N at one side, as seen m ejected and also through which a cartridge may be inserted when the arm is used as a single-loader, a common construction of receiver.

To support the breech-piece at its forward end and maintain it in its proper relation to the barrel, a longitudinal groove is made in one side of the receiver,'and on that side the extractor-hook P or other suitable projection extends into this groove. The groove is shown in Fig. 8 and is of a length sufficient only to permit the required forward movement of the receiver, the projection from the extractor or breech-piece into the groove working freely therein, and so as tov permit the natural rising movement of the forward end of the breech-piece, while the rear end is held as before described, such'rising movement being due to the inclination of the spindle with relation to the barrel.

Within the breech-piece the firing-pin Q is arranged, extending from the forward end of the breech-piece through to the rear end, as

seen in Fig. 1.

R represents the hammer, arranged in'the tubular spindle F. The tail S of the hammer extends rearward through the-end of the spin- Fig. 2, through which the shell may be die and through the end of the tube G, and

within the spindle a spiral spring '1 is arranged around the tail of the hammer, adapted to bear forward against a shoulder U on the hammer and against'a corresponding shoulder V at the rear end of the spindle, and so that as the hammer is forced rearward the spring will be compressed that the reaction of the spring may force the hammer forward. The nose of the hammer stands in such position with relation to the firing-pin that when the parts are in the closedposition the hammer may strike the rear end of the firing-pin, as usual in the arrangement of hammers in other arms. Naturally the hammer will move backward and forward with the spindle, and

this condition is taken advantage of as a means for cocking the hammer, and this is produced by means of a scar W, hung upon a pivot X at the rear end of the receiver and below the hammer, as seen in Fig. 3. The scar is provided with aspring Y, the tendency of which is to force the nose or rear end of the sear upward against the hammer.

The rear end of the tail of the hammer is provided with a head Z of larger diameter,

than the opening through the end of the tube G, and the length of the tail of the hammer is such that the head Z will strike the end of the tube G before the receiver shall have reached its extreme forward position, and, as

seen in Fig. 6, thereby arresting the forward movement or advance of the hammer with the receiver, and so that when the hammer is so arrested the receiver will continue its forward movement and compress the spring and the sear W may swing up forward of the hammer or the shoulder thereon, as seen in Fig. 6.

Then when the receiver returns, asin the closthe hammer free to be thrown forward by the force of its spring, and in which forward movement the hammer will strike the firingpin Q and communicate its blow to the primer of the cartridge.

In order to conveniently detach the barrel and receiver from the stock, the rear end of the tube G is constructed with an elongated opening b, (see Fig. 12,) and the head Z of the tail of the hammer is of a shape corresponding to the opening I), (see Fig. 13,) but normally stands at an angle to the said opening 1;. It, therefore, the receiver and spindle be turned to bring'the head Z into line with the opening b, then the head of the tail of the hammer may freely pass through,so as to permit the spindle to be withdrawn, and then when returned after the head of the tail of the hammer has passed through the opening I) in the rear end of the guide-tube G the receiver is turned into its proper plane with the stock, which brings the head of the tail of the hammer across the opening in the tube, so as to again interlock the har'nmer with thetube.

To permit the separation of the receiver from the stock, the pin K through the breechpiece is first removed, so as to disconnect the breech-piece from the stock. Then the parts are readily separated.v

To engage the stock with the receiver, so as to prevent their accidental separation, a springbolt d is arranged (see Fig. 3) in the stock, with a beveledor rounded nose adapted to engage a corresponding notch in the spindle when the parts are in the closed position, but so as to yield to a force applied to draw the spindle from its home position. As a further lock to hold the receiver and stock in their closed position a dog e is hung in the stock or mend, as upon a pivot f, the nose 9 of which is adapted to engage the receiver,

as seen in Fig. 5, and also to engage the sear when in the cooked position, as-seen in broken lines, Fig. 1. The dog is provided with a spring-bolt h, working over a corresponding cam '5, here represented as in the guard, to yieldingly hold it in either its engaged ordisengaged position, and the tail of the dog extends into the guard and terminates in a finger-piece Z, by which it may be conveniently operated by the same finger which pulls the trigger.

As thus far described the arm is applicable to single-loading purposes.

As a magazine-arm a carrier m is arranged in the receiver, below the breech-piece, and hung upon a pivot n at the rear,so as to swing in a vertical plane, as,from the down position in Fig. 1 to that seen,;,in Fig. 6. In the down position the carrier stands at the rear of the magazine C, and so that the rearmost cartridge in the magazine may pass onto the carrier in the usual manner, and then as the carrier rises that cartridge will be presented between the forward end of the open breechpiece and the rear end of the barrel, so that as the parts are closed the cartridge may be forced from the carrier into the barrel, as usual in magazine firearms. The carrier at its rear end is provided with an upward extension u, by which it may be operated by coming in contact with the breech-piece at the extreme movements, as usual in: this class of carriers, and so that as the breech-piece'approaches its extreme rear position, as seen in Fig. 6, the carrier will be raised, and then as'the parts are closed the projection to will strike the breech-piece and be returned to its down position. I i a To yieldingly hold the carrier in its down position, and so that it may serve as a trap or cover for the opening through the bottom of the receiver for the introduction of cartridges to the magazine, the carrier is provided with a spring 10, which being engaged by the breechpiece in its closed position, as seen in Fig. 1, will yieldingly hold the carrier in its down position, but so that the carrier may be turned inward 'for the introduction of cartridges into the magazine. As here represented the spring p is employed in connection with an L-shaped lever q. (See Fig. 7.) This lever is hung to the carrier by its downwardly-projecting arm upon a pivot r and so as to swing in a horizontal vertical plane. The other arm of the lever extends across and bears upon the spring p. This lever is constructed with a nose s, which as the carrier rises is adapted to engage a corresponding notch t in the receiver, and so as to yieldingly hold the carrier in the up position during the transfer of acartridge from the carrier to the barrel, the nose of the lever easily passing from its engagement with the receiver under the force of the closing movement, so as to release the carrier for its cartridge follows the latch it until the cartridge reaches its position on the carrier.

To prevent the rear movement of the colhmn of cartridges after the carrier has risen i'or the transfer of a cartridge to the .barrel, a iatch a (see Figs. 8, 9, 10, and 11) is provided in a recess in the side of the receiver, the nose w of the latch being adapted to extend inward, so as to engage the head of a car: tridge, as seen in Fig. 10, but tobe withdrawn therefrom, so as to leave the head of the cartridge free, as seen in Fig. 11; The latch is hung in the receiver upon a pivot :0, so as to swing laterally, and extends longitudinally in the receiver. I

The latch is projecting tail is a spring 2,

provided with a rearwardlyy, and combined with thelatch thetendency of which is to force the latch into the engaging position. (Seen in iEig. 10.) At the rear end the tail of the latch is constructed with a beveled shoulder 2, and the breech-piece is constructed. with a corresponding cam-shaped surface 3, and which cam-surface 3 as the breech-piece approaches its closed position will engage the shoulder i, of the tail of the latch, and so as to force that tail inward and correspondingly turn the nose outward, as seen in Fig. 11, and so that the rearmost cartridge in the magazine may escape and pass onto the carrier. Then as the receiveris drawn forward from the breechpiece the cam 3 of the carrier escapes from the shoulder 2 of the latch, when the nose of the latch will be forced in ward by its spring, so as to engage the head of the next cariridge, as seen in Fig. 10, which engagement will occur before the said rearmost cartridge shall have reached its rear position on the carrier.

For the convenience of rapid firing the tail ii of the sear, with which the trigger engages, is beveled upon its rear end, as at 5, and so that should the trigger be held in the drawn position when the receiver is returned to the closed position-the beveled end 5 will pass below the trigger, as seen in Fig.3, so as to draw the sear out of engagement with the hammer. Thus the act of bringing the parts to the closed position will operate automatically to discharge the hammer, it only being necessary that the operator shall hold the trigger in the drawn position or that it be held in that position by some suitable device.- Then the firing becomes practically automatic, and consequently limited only to the rapidity with which the barrel and receiver may be moved backward and forward while the operator holds the gun to the shoulder.

While preferring the mechanism described to be arranged in thereceiver, it will be evident that various known mechanisms may be arranged in the receiver, so that the receiver, with its guiding-spindle, may operate in the forward movement of the receiver to produce the opening movement of the breech-piece and in the closing movement of the receiver to produce the closing movement of the breechpiece. It is also evident that other known arrangements of hammers may be substituted for the one described. Such modifications are 'ceiver constructed with too well known to require particular refer- I once or illustration. The invention is therefore not to be understood as limited to the specificconstruction of parts, except as hereinafter particularly recited.
