0 all whom it may concern:

Be it known that 1, JOHN M. BROWNING, of Ogden, in the county of lVeber and Territory of Utah, have invented a new Improvement in Breech-Loading Firearms; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters 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

My invention relates to an improved breechloading tubular-magazine concealed hammer repeating firearm designed, primarily, to be used as a shotgun, the object being to produce a simple, strong, compact, reliable, and safe arm, constructed with particular reference to ease and convenience of operation, to the better inclosure and protection of the action mechanism, to locking the breechbolt at a point close to the gun-barrel, to prevent the hand from being injured by the projection of the rear end of the breech-bolt through the frame when the gun is open, and to prevent the gases of explosion from being thrown back into the face of the sportsman.

lVith these ends in view my invention consists in a firearm having certain details of construction and combinations of parts, as will be herein after described, and pointed out in the claims.

In carrying out my invention, as herein shown, I form four transverselyarranged locking notches or recesses A in the upper wall or top A of the frame A of the arm, the said upper wall or top being unbroken throughout its length, as shown in Figs. 1 and 3. These recesses or notches receive a corresponding number of transverse upwardly-proj ecting locking-ribs B, formed upon the upper face of the breech-bolt B, which is con fined to longitudinal movement back and forth in the frame, except at the end of its forward movement, where it is permitted to move up and down for the entrance of its locking-ribs B into, and their clearance from, the locking notches or recesses A. I do not limit myself to employing four locking-recesses and four ribs, as the number thereof may be varied, as desired. Two links B 13 connected at their upper ends with the breechbolt, from which they depend, are connected at their lower ends with a breech-bolt slide C, which is moved back and forth in the frame of the arm by means of its connection, as will be described later on, with the rear end of an action-bar D, the forward end of which is attached to a sliding handle D, mounted upon the tubular magazine E, located directly under the gun-barrel F, the said handle being in inclined positions and with their upper ends in advance of their lower ends. W'hen, therefore, the slide is moved forward to complete its forward movement, the links are brought into upright positions, as shown in Fig. 3, so that the breech-bolt is lifted vertically for a distance sufficient to enter all of its transverse locking-ribs into the locking notches or recesses in the frame, whereby the breech-bolt is firmly locked in its closed position. On the other hand, the slide begins its rearward movement before the breechbolt, whereby the links are turned down into their inclined positions, as shown in Fig. 0, and the breech-bolt drawn downward to clear its locking-ribs from the locking-notches of the frame, after which it may be moved directly rearward into its full open position, as seen in Fig. 10.

By constructing the arm with locking notches or recesses and the breech-bolt with locking ribs or shoulders, as described, I am enabled to entirely dispense with the use of a recoilblock and means for operating the same, whereby I simplify the arm. Furthermore, I thus lock the breech-bolt at a point very nearits forward end and close to the gunbarrel, whereby I secure a solid construction and reduce to a minimum the springing of the parts under the force of the recoil following the explosion of a cartridge. On the other hand, when a recoil-block is used it looks the breech-bolt at or near the extreme rear end thereof, giving a chance for the breech-bolt to spring throughout its entire length. By my invention, therefore, I secure superior resistance and stability in the arm under the shocks of use.

The breech-bolt is provided with two extractors b, respectively located in recesses formed in its opposite sides and projecting slightly forward of its'forward face. When the breech-bolt reaches the limit of its forward movement and before it is lifted into its locked position, the said forward ends of the extractors enter notches Z) Z), formed to receive them, at opposite points in the rear end of the gun-barrel F, as shown in Fig. 7. In order therefore to provide for the vertical movement of the breech-bolt in looking it into extractors are flexibly connected or articulated with the breech-bolt, so that their rear ends may belifted up and down while their forward ends remain entered in the said notches. It will be noticed that, as shown in Fig. 6 of the drawings, the extractor lies in a horizontal plane with its forward end entered into one of the notches in the gun-barrel, and that, as shown in Fig. 3 of the drawings, the extractor has been brought into an inclined position by the lifting of its rear end, consequent upon the lifting of the breech-bolt in looking it into the frame.

The particular construction of the breechbolt and extractors for the flexible connection of the latter with the former may, of course, be widely varied, and I do not limit myself to any particular way of securing the result mentioned. The extractor shown in Figs. 3 and 6,for instance, is constructed near its rear end with a Vertical slot 79 receiving a vertical pin Z2 mounted in the breech-bolt. The other extractor,which is not shown,is adapted in any suitable manner to have its rear end moved up and down for the purpose set forth.

In order to prevent the firing-pin B mounted in the breech-bolt B, from being broken by the snapping of the concealed hammer G of the arm when there is no cartridge in the gun, I connect the said pin-with a spring B, Figs. 13 and 14, located in the breech-bolt and arranged to exerta constant effort to pull the pin forward, so as to project its forward end beyond the forward face of the breechbolt and draw its rear end slightly within the rear face of the breech-bolt, and therefore out of range of the action of the hammer, should the same be snapped without a cartridge in the gun. For the positive retraction of the firing-pin after the gun has been fired I provide the rear end of the pin with a depending nose B and the rear face of the upper end of the rear link B with a corresponding nose B Vhen the breech-bolt is in its locked position, the nose B does not interfere with the proper longitudinal movement of the pin. In Fig. 13 of the drawings the breech-bolt is represented in its said locked position and the firing-pin is drawn forward by its spring B, whereby its forward end is projected beyond the front face of the breech-bolt and its rear end drawn within the same. breech-bolt and slide in the positions shown in this figure it is clear that if a cartridge were introduced into the gun, its head would push the firing-pin rearward against the tension of the spring B, so that the rear end of the firing-pin would project beyond the rear face of the breech-bolt, as shown in Fig. 14, and into position to be struck by the hammer for exploding the cartridge. \Vhen there is no cartridge in the gun, the spring will assert itself, as aforesaid, and hold the firing-pin in the position shown in Fig. 13; but just as soon as the slide 0 begins its rearward movement the nose B of the rear link B acts upon the depending nose B of the firing-pin \V ith the so as to positively retract the same against the tension of the spring 13*, as shown in Fig. 14:. The firing-pin being thus positively retracted by means of the rear link is held in such retracted position while the breech-bolt and slide are moving rearward into their open positions, and also while they are moving forward into their closed positions and until the links are brought into their vertical positions again by the final forward movement of the slide, when the breech-bolt is lifted into its locked position. The link then relieves the firing-pin, which is retained in its retracted position, with its rear end projecting beyond the rear face of the breech-bolt, by the cartridge in the gun-barrel, if one is there; but if there is no cartridge in the gun-barrel the spring B asserts itself to draw the firingpin inward into a position in which it is protected against injury from the snapping of the hammer.

For lockin g the slide and breech-bolt in their closed and locked positions and for preventing not only the premature snapping of the hammer, but any snapping of the hammer until the gun is closed, I employa sliding safetylock H, arranged for vertical movement and mounted in the lower tang I of the gun at a point just in front of the trigger-guard 1 thereof, the lower end of the lock being exposed and having its forward face roughened to facilitate its engagement by the fingers. By reference to Fig. 4c of the drawings it will be seen that the opposite edges of this sliding safety-lock are constructed with ribs h, taking into the ends of a guideway formed in the tang. The upper end of the lock coacts with a forwardly-inclined beveled locking-shoulder 0, arranged transversely upon the extreme rear end of the lower face of a lug O, extending rearwardly from the slide C. When the slide is in its closed position, the upper end of the sliding safety-lock extends up behind the said shoulder 0, whereby the sliding lock locks the slide, and hence the breech-bolt, in its closed position. The sliding safety-lock is maintained in its normally elevated position by means of a spiral spring H, located in part in a recess formed in the trigger-guard I and engaging at its upper end with a hook H formed integral with the sliding lock and extending rearwardly from the rear face thereof. The sliding lock is further constructed at a point slightly above its longitudinal center with a slot H which receives a lug G, extending forward into it from the lower end of the concealed hammer G, the said lug and slot being constructed and arranged so that the lower edge of the lug engages with the lower end wall of the slot just before the hammer reaches its down position, and so that the hammer will during the completion of its forward movement push the sliding lock down against the tension of its spring H fora distance sufficient to clear its upper end from the bev eled locking-shoulder c of the slide 0; The

snapping of the hammer in firing the gun therefore operates to depress the sliding lock and unlock the slide and breech-bolt preparatory to the opening of the gun after firing it. The hook H of the sliding lock takes into a notch g, formed in the lower end of the hammer at a point in front of and above a notch 9, formed therein to receive the nose located at the forward end of the trigger J, the difference between the position and elevation of these two notches causing the hook of the sliding lock to act on the hammer before the trigger acts thereon, whereby the sliding lock will hold the hammer in a little lower position or a little farther back than the trigger will.

On account of the construction just above described the sliding safety-lock virtually takes the place of the trigger for holding the hammer in its cocked position until the' breech-bolt and slide are in their closed po sitions when the gun is being fired as a repeater by holding back the trigger and operating the handle rapidly. When the gun is being fired in the manner described, with the trigger pulled back so as to entirely clear the hammer, the hook H of the safety sliding lock springs into the notch g of the hammer, when the same is thrown back into its cocked position by the engagement of the slide 0 with its forward face in the rearward movement of the slide. The hammer is then held by the sliding safety-lock in its cocked position until the slide is virtually in its closed position, when the beveled shoulder upon the lower face of its extreme rear end engages with the upper end of the lock and pushes the same downward far enough to disengage the hook from the hammer, which is thus automatically released and allowed to fly forward under the action of its spring. This action of the slide in pushing down the lock and releasing the hammer takes place immediately before the slide comes to rest, which it has just time enough to do before the hammer springs forward. It is to be understood, furthermore, that by virtue of the direct coaction of my improved sliding safety lock with the hammer the snapping of the same is prevented until the breech-bolt and slide are in their fully-closed positions, for the rearwardly-projecting hook of the lock is not disengaged from the hammer until the lock is pushed down by the going of the slide into its fully-closed position. Therefore, if the trigger is pulled to release the hammer before the slide has gone into its closed position, the hammer will not be released, so that the premature snapping of the hammer is prevented and any snapping of it rendered impossible until the gun is fully closed. Here I may say that it must be understood that.

the lock is always engaged, when the gun is open, in holding the hammer in its cocked position, for the reason that the sliding safetylock is only pushed down out of engagement IIO although it has entered into the notch g, has

done so without engaging the hammer so as to have any restraining action thereupon. It follows from this that when the sliding safetylock is pushed downward by the going of the slide into its fully-closed position ,whereby the hook is disengaged from the hammer, the same will be lifted a trifle by the hammer-spring G before it is engaged by the trigger, which then holds the hammer in its cocked position, independent of the sliding safety-lock and until the gun is fired. I may also add that the gun may be closed without cooking the hammer by holding the trigger back during the forward movement of the breech-bolt slide, whereby the hammer is permitted to follow the breech-bolt slide forward without being caught either by the trigger or by the rearwardly-extending hook of the safety-lock. The function just described will be availed of when the gun is closed with a cartridge in the gun-barrel and it is desired to uncock the hammer without exploding the cartridge. For this purpose the safety-lock is pulled down by the fingers and the sliding handle moved rearward with the trigger held back. Then, during the following forward movement of the handle, the trigger being still held back, the hammer will follow the breech-bolt slide, and comes into its down position without being engaged by the trigger or the hook of the safety-lock, which will be lifted by its spring, but not elevated enough to lockthe breechbolt slide, which is left free to be moved back by the rearward movement of the handle. By preference the sliding safety-lock will be operated for unlocking the slide from the breechbolt by drawing it down by grasping its projecting lower end with the fingers. I may add in this connection that the lug C at the rear end of the slide engages with the forward face of the hammer at the base thereof in such a manner that it holds the hammer away from the firing-pin unless the slide is in its fully-closed position.

To prevent the gun from being fired after it is closed and the hammer is cooked, I provide the trigger with a safety-clutch K, for the reception of which the upper portion of the trigger is constructed with a longitudinal chamber J, open at both ends. The forward end of this clutch is constructed with two jaws 7a and is, adapted when it is pushed forward to be engaged with a transverse web or tie I Fig. 11, after which the trigger cannot be rocked on its pivot. The said jaw 70 eX- tends downward into the trigger-guard and has its face roughened or hatched so that it may be readily engaged by the fingers for pushing the clutch forward or back. The rear end of the clutch is engaged by the trigger-spring J which thus has not only the function of operating the trigger, but also of holding the clutch in any position into which it may be moved by the sportsman.

For the purpose of lifting the carrier L, the rear end of which is pivotally connected with the lower tang I by means of a horizontallyarranged pin L, I employ a rocking lever M, which is located in a vertical recess )1, Fig. 5, formed to receive it in the left-hand wall of the forward end of the said lower tang. This lever is fulcrumed upon a horizontal pin or stud M mounted in the tang and projecting into the said recess, the lever beinghung so loosely upon the pin or stud that it is free not only to rock back and forward in a vertical plane, but also to tip laterally in a plane at a right angle to the longitudinal plane of the gun. A spring M interposed between the lever and the bottom of the said recess, exerts a constant effort to hold the lever in an upright position, in which it clears the bottom or inner wall of the recess. The forward end of this lever terminates in a finger m, which coacts with the lower edge of the rear end of the action-bar D and also with the lower edge of a flange depending from the left-hand side of the slide'O. For the purpose of this coaction the said edge of the action-bar has a notch d formed in it, while the said flange C has formed in it a clearancespace 0 and an operating-bevel 0 all shown in Fig. 15. At the beginning of the opening movement of the gun the bevel 0 which is formed at the extreme rear end of the said flange O of the slide 0, engages with the finger m of the rocking lever M and tilts and crowds the same inward into its containingrecess M against the tension of the spring M After this the said finger of the lever virtually rides upon the inner face of the flange O and upon the inner face of the rear end of the action-bar D until the notch d of the bar is brought into coincidence with the finger m, at which time the spring M acts to lift the lever back into its vertical position and thus to move the said finger laterally outward into the said notch. The movement of the finger of the lever into the notch of the bar takes place just at the time when the slide reaches the extreme limit of its rearward movement. When, now, in the closing of the gun the slide and bar are moved forward, the rear wall of the said notch engages with the rear edge of the finger on, so as to cause the lever M to be rocked on its pivot, whereby the finger m of the lever is lifted against a projection L formed in right position at the rear end of the carrier, which is then lifted into its elevated or discharging position, as shown by broken lines in Fig. 10. When the carrier has thus been lifted into its elevated position,

the finger m of the rocking lever rides out of the notch d, but is held down so as to hold the carrier up by means of the flat lower edge of the action-bar and the flat lower edge of the flange of the slide. The lever is thus maintained in its rocked position until its finger m reaches the clearance-space c in the flange C of the slide. The clearance thus afforded permits the rocking lever to rock rearward on its pivot, its finger m rising into the said space. At the same time that the lever is rocking rearward, as described, the carrier is forced downward by the engagement of its forward end with the forward end of the slide. During the subsequent forward movement of the slide the finger m rides out of the clearancespace and upon the inner face of the rear end of the flange C of the slide and over the operating-bevel 0 thereof until, when the slide is in its fullyclosed position, the said bevel stands in front of the said finger. At this time the spring M before referred to, operates to push the rocking lever outward against the adjacent side wall of the frame. The next time the. gun is opened the bevel c engages with the finger m and crowds the lever in ward again, and so on.

For connecting the rear end of the actionbar with the slide I provide the slide with a transversely-arranged spring-actuated coupling-pin N, Fig. 15, the longitudinal movement of which is controlled by a small stoppin n and which is normally projected by means of a coiled spring N, engaging with its inner end. This pin, when projected, enters a suitablehole D of corresponding diameter formed in the extreme rear end of the action-bar. For access to this pin the frame A is provided in the right place with a very small aperture a. For disconnecting the slide and action-bar they are moved until the pin is brought into alignment with the opening a,

through which a small wire or other similar object is then introduced for pushing the pin inward, so as to clear it from the action-bar, after which the bar and slide may be drawn apart. This spring'actuated pin therefore makes the connection and disconnection of the bar and slide a very easy matter.

The cartridge-stop which I employ in this gun consists of a long lever 0, hung 011 a pin 0 and bearing directly against the inner face of the righthand wall of the frame. It is constructed at its forward end'with a depending inwardly-turned stop-finger O and with an operating-bevel 0 the latter being located upon its upper edge in position to be engaged by the forward end of the slide 0, so that when the slide is moved forward the forward end of the lever is depressed to retire the stopfinger, as shown in Fig. 7, and permit the cartridges to feed rearward out of the magazine E. On the other hand, when the slide is moved back into its open position its rear end engages with the operating-bevel 0 formed at the rear end of the lever, which the slide depresses, so as to lift its forward end and raise its stop-finger into the position shown by broken lines in Fig. 7, where it engages with the head of the rearmost cartridge and holds in check the line of cartridges in the magazine. WVhen the slide is in its forward position, the stop is pushed down out of the way, so that the rearmost cartridge in the magazine is free to move out of the same, which it does until stopped by engaging with the forward edge of the carrier, which is rounded out. The cartridge remains in this position until the slide, which is then located directly over it, is moved back.

Then this takes place, the upper edge of the cartridge is released, and the magazine-spring, which is not shown, acts on the cartridge to cause it to ride up over the rounded edge of the carrier and onto the same; but just before the cartridge next ahead of the one on the carrier emerges from the magazine the slide engages with the bevel O at the rear end of the lever O, causing the forward end of the lever to be lifted and the stop-finger 0 presented directly in front of the head of the rearmost cartridge in the magazine.

By reference to Fig. a of the drawings it will be seen that the frame in loses and protects the action mechanism in a degree unusual in this class of guns, inasmuch as it is solid except for the ejection opening A formed in its right-hand wall, and for the long opening A, formed in its bottom for the reception of the lower tang and for the feeding of cartridges into the magazine under the carrier, which is lifted for the purpose. I wish to call attention to the fact that the breechbolt and slide are inclosed, and that neither of them projects through the frame when the gun is open, so that there is no danger to the sportsman of having his hands injured, and, furthermore, there is no danger to him from the gases of explosion, which sometimes fly back into the face of the sportsman in guns in which there are cuts in the top of the frame.

It is apparent from the suggestions made in the foregoing description and of other changes which mayobviously be made, that I am not limited in carrying out my invention to the exact construction shown and described. Nor am I limited to using the several features of my invention in combination, for I may use them separately in different guns or in any combinations. Nor do I limit myself to their use in connection with tubular-magazine guns or repeating-guns. I would therefore have it understood that I hold myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of my invention.
