MAGAZINE-FIREARM.

SPECIFICATION forming part of Letters Patent No. 499,007, dated June 6, 1893.

Application filed October 15, 1892.

To all whom it may concern:

Be it known that 1, JOHN M. BROWNING, of Ogden, in the county of Weber and Territory of Utah, have invented a new Improvement in Magazine Firearms; and I do hereby declare the following, when taken in connection with accompanying drawings and the letters of ref erence marked thereon, to be a full, clear, and Z exact description of the same, and which said drawings constitute part of this specification, and represent, in v Figure 1, a side View of the arm broken 1 away at front and rear; Fig. 2, a top view of the same; Fig. 3,a longitudinal sectional side view showing the parts in the closed or norj, mal position; Fig. 4, a transverse section on line 0coc of Fig. 3; Fig.5, a transverse section cutting on line yy of Fig. 3; Fig. 6, a top view of the sear; Fig. 7, the same as Fig. 3, showing the parts in the open position and representing-a pack of cartridges in the magazine chamber; Fig. 8, a transverse section cutting on line 2-2; of Fig. 3; Fig. 9, a detached view illustrating the operation of the sear upon the hammer.

This invention, relates particularly to an improvement in that class of magazine fire- 3 arms in which the magazine is in a chamber directly below the breech-piece, the cartridges being contained in a pack, so that several car- I tridges are simultaneously introduced into the magazine when the breech-piece is in the open position, the breech-piece having a longitudinal reciprocating movement, parts of the invention being applicable to other ar-j rangements of magazine, and also to single breech-loading arms, the object of the invention being chiefly to produce the opening movement of the breech-piece by means of a lever which is drawn toward the person as the 1 arm is held at the shoulder, and so that manipulation of the arm may be produced without moving the trigger-finger from the triggerguard or operating lever, and the invention consists in the construction as hereinafter described and particularly recited in the claims.

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

; as a trunnion. V piece is constructed with a downward projec- C, represents the breech-piece, which is ar- Serial No. 448,971.. (No model.)

ranged to movelongitudinallybackward and forward,as from the position in Fig. 3, to that seen in Fig. 7, and return; at its forward end it is guided in a longitudinal line by means of a stud D, projecting laterally into a corresponding longitudinal groove E, in the receiver, see Fig. 8, and so that the breechpiece may swing up and down between the sides of thereceiver, turning on the stud D,

At its rear end the breechtion F, on its under side, in which is constructed a cam-slot G, inclined upward and forward.

When the breech-piece is in the closed potion, its rear end is adapted to drop forward of an abutment H, in the receiver, see Fig. 2, and so as to rest against said abutment to resist recoil, but when the rear end of the breechpiece is raised, as represented in broken lines Fig. 3, so far to take the breech-piece above the abutment, then the breech-piece may be moved longitudinally rearward.

The receiver in rearof the breech-piece is constructed with alongitudinal slot I, through which the downward projection F, of the breech-piece may run as the breech-piece is moved rearward, this downward projection 1 corresponding substantially in thickness to the width of the-said slot I. In the receiver upon a pivot J, in rear of and below the breech-piece, a lever K, is hung, see Fig. 3. This lever extends forward, and is shaped to form a trigger-guard L, the movement of the lever upon its pivot being from the closed position seen in Fig. 3, to the wide open position seen in Fig. 7. A link M, is hung to the lever upon a pivot N, forward of the pivot J, on which the lever is hung. The link extends forward from its pivot. The link is bifurcated so as to embrace thelever upon opposite sides, and is also bifurcated or recessed at its forward end to embrace the downward projection F, of the breech-piece, or, what is the same thing, the link connection may be a pair of links, one upon opposite sides of the lever, and extending to corresponding sides of the downward projection F, of the breech-piece. At the forward ends the links are connected by a pin 0, which extends through the cam slot G, of the breech piece, and the pin is longer than the thickness of the links, so as to project at each side, and in the receiver at each side a groove P, is formed, into which the ends of the said pin 0, extend, and so that the forward ends of the links will be guided in a longitudinal path, this path being here rep resented as inclined from the front end down ward and rearward, see Fig. 7. Consequently as the lever K, is turned from its forward or closed position, as seen in Fig. 3, to its rear or open position as seen in Fig. 7, the links will be drawn backward with the lever, the end connected with the links moving with the lever, while the forward ends of the links will be guided by the slot P. When the breechpiece stands in its closed position, and the lever in its forward or closed position, the links stand with the pin 0, in the upper and forward end of the cam slot G. As the lever commences its rear movement, and as in such movement the forward ends of the links cannot escape from the direction of the grooves P, it follows that the projecting ends of the pin 0, will operate in the cam groove G, so as to cause the rear end of the breech-piece to rise, as represented in broken lines Fig. 3, which rise is suflicient to take the breechpiece above its supporting abutment, and when the breech-piece is so raised, the pin 0, has passed to the rear end of the cam slot G, as represented in broken lines Fig. 3. From this point the continued movement of the lever K, will draw the breech-piece rearward until it reaches its full open position, as seen in Fig.7. In this movement the rear end of the breech-piece rides upon the upper side of the receiver, while its forward end will be guided as before described. Then on the return of the lever K, the breech-piece will be moved forward until it reaches its closed position rep- I resented in broken lines Fig. 3, at which time its rear end has passed forward of the abutments. Then the pin 0, again acts in the cam slot G, and so that in completing the forward movement of the lever, the rear end of the breech-piece will be drawn down to its closed or locked position, as seen in Fig. 3.

Q, represents the hammer, which is arranged in rear of the breechpiece, and is adapted to slide longitudinally in the path of movement of the breech-piece. The hammer projects up through the slot I, in the top of the receiver, and so that as the breechpiece is moved rearward, the hammer will be forced rearward accordingly, and compress its spring R, the hammer being adapted to strike the firing-pin in the breech-piece in the usual manner. The hammer is provided with a thumb piece by which it may be moved rearward against its spring independent of the movement of the breech-piece if desired.

S, represents the sear, which is in the form of a lever, hung below the hammer upon a pivot T, and so as to swing in a vertical plane; its nose U, at the rear is adapted to engage a corresponding notch V, on the under side of the hammer, and so as to hold the hammer in the cocked position.

W, represents the sear-spring, the tendency of which is to yieldingly force the nose of the sear toward the hammer. The tail X, of the sear extends forward of its pivot.

In the link M, the trigger Y, is hung, upon a pivot Z, and so as to swing in a vertical plane, and the relation of the trigger to the sear is such that when the breech-piece is in its forward or closed position, as seen in Fig. 3, the rear end of the trigger will stand beneath the forward end of the tail of the sear. The finger-piece a, of the trigger extends down through a corresponding opening in the lever K, and within the trigger-guard L, so that when the parts are in the closed position, the trigger may be pulled by the trigger finger in the usual manner, to release the hammer, but so soon as the operating lever K, commences its rear movement, the triggerguard is-taken away from the trigger, so that the trigger is disengaged from the finger, and at the same time the trigger itself drops with the link M, from possible engagement with the soar, and this relation exists until the parts are returned to the closed position, so that if the hammer be held at the cooked position, the sear cannot release the hammer until the parts are in the proper closed and locked position.

The extent of movement of the .hammer rearward is the same as that of the breechpiece, but so longa movement of the hammer upon discharge would be greater than desirable. Consequently the cock-notch V, of the hammer is made distant from the forward end of the hammer corresponding to the length of stroke required. The hammer follows the breech-piece in return until the full cock notch is reached, when that notch will engage with the seer and hold the hammer in the cooked position, while the breech-piece is returned preparatory to firing.

When the breech-piece is in the closed position and the hammer cooked, it is desirable that the hammer be provided with a stop to prevent its being drawn backward by the thumb. To accomplish this result the hammer is constructed with a shoulder 1), forward of the cock notch V, and the sear is constructed with a corresponding shoulder a, forward of itsnose, and so that when the hammer stands in the cocked position, as seen in Fig. 9, the nose of the sear is engaged with the full cock notch V. N ow if the attempt be made to draw the hammer rearward from this point, the shoulder b, of the hammer will engage the shoulder c, of the sear, and thus prevent any considerable extent of movement of the hammer by the action of the thumb.

To prevent the engagementof the shoulder a, with the shoulder b, of the hammer when the hammer is moved rearward under the action of the breech-piece, the sear is preferably constructed bifurcated from near its rear end forward, the two legs extending on opposite sides of the downward projection F, of the breech-piece, and upon the upper side in rear of the pivot, the sear is constructed with an upward projection forming a cam d, and the breech-piece carries a corresponding stud e, adapted to pass over the cam d, of the sear. Consequently as the breech-piece approaches its rear position, and before the shoulder 0, can have engaged the shoulder b, of the hammer, the nose of the sear will be depressed by the cam cl and stud e, as represented in broken lines Fig. 9, so far as to permit the shoulder 12, of the hammer to escape the shoulder a, of the sear. Then as the breech-piece and hammer reach their extreme positions, the nose of the sear rises forward of the shoulder f, on the hammer so as to engage the hammer and relieve the breech-piece from the pressure or force of the hammer spring. Under this arrangement or locking of the hammer in its extreme rear position, the cam d, of the sear and the corresponding stud e on the breech-piece come into action when the breech-piece commences its forward movement so as to release the hammer from its locked position. The depression of the sear by the stud e,will throw the nose of the hammer from the shoulder f,

and liberate the hammer, so that it may follow the breech-piece until the full cocked position is reached. The hammer is provided with a half cock notch g, to permit the hammer to be drawn and held at half cock as occasion may require.

In the receiver, beneath the breech-piece, the magazine chamber h, is arranged in the usual manner, and provided with a suitable follower i; the chamber is open in the usual manner from the top, when the breech-piece is in the open position as seen in Fig. 7, and so that a cartridge pack in which the cartridges are supported in a holder j, may be introduced into the magazine, the follower being depressed in such introduction, in the usual manner. This arrangement of magazine is too well known to require particular description. In the bottom of the magazinechamber is an opening is through which the holder j may be forced after'the cartridges it carried have been successively transferred to the barrel, such removal occurring by the introduction of the next pack of cartridges; this is also a common and well known device.

The pack is locked by means of a dog Z, hung upon a pivot on at the rear of the pack, the nose of the dog being adapted to engage a corresponding notch in the back of the holder; this is a well known device.

The operating lever K, extends forward to form a cover n, for the opening in the bottom of the magazine, see Fig. 3.

The pawl Z, is provided with a spring 0, adapted to yieldingly press the dog into engagement with the cartridge-holder, and the spring 0, projects rearward, so as to engage the lever when in the closed position, as seen in Fig. 3. The nose of the dog extends down so that it may be conveniently reached when the operating lever is turned away, and so that the cartridge holder may be thereby released from engagement with the dog, and removed from the receiver should occasion require such an operation.

It will be understood that the breech-piece is provided with the usual extracting devices for the withdravfal of the exploded shell from the barrel, or the cartridge if it be not exploded.

The arrangement of the operating lever so as to swing downward and backward in opening, enables the operator to bring the opening force toward the shoulder instead of in the opposite direction, as in arms where the lever is hung forward and the movement is downward and forward in opening. This arrangement results in a more steady holding of the gun against the shoulder, because the greater force required is in the opening movement, and the lesser force of closing does not tend to throw the gun out of line, as must always be the case where the heavy opening force is applied in the opposite direction.

The illustration of the arrangement of the operating lever hung below the breech-piece and so as to swing backward and downward in opening, in connection with the breechpiece shown, will be sufficient to enable others skilled in the art to apply this arrangement of lever to other constructions and arrangements of breech-pieces without further illustration.

Instead of the magazine represented, other known arrangements of magazine and carrier may be substituted therefor, such substitution being too apparent to require particular rel and the receiver thereof, and a longitudinally reciprocal breech-piece; of an operatinglever hung by its rear end below the receiver and extending forward from its pivot, and moving downward and-backward in opening; and means attached to the said lever forward of its pivot positively connecting it with the said breech-piece, substantially as described, and whereby the said breech-piece is opened by the downward and backward opening movement of the lever.
