My invention relates to improvement in magazine-guns, the object being to produce an easily-operated, convenient. and effective gun of the type in which the breeclroolt is operated by two toggle-links which hoid it in its closed position.

With these ends in view my invention consists in a gun having certain details of construction and combinations of parts, will be hereinafter described, and pointed out in the claims.

In carrying out my invention I employ, as herein shown, a knob-like handle 2, formed with a threaded stem 3, adapting it to be screwed into the threaded opening 4, Fim 35, formed for its reception. in the rear end of an action-slide 5, formed upon its upper and lower edges with ribs 6, which guide it back and forth in a long slot 7, lTormed for its reception in the inner face. of the righirhand wall of the gun-frame or receiver 8, which is formed with s slot f), representing the dis tsnco traveled by the hsudie forward and back, and in which the handleis confined to pure reciprocating movement. This handle might, however, be replaced by some other form of actuator connected th the slide, such as what is known as sliding-action fore-arm ora swinginghendle-iever. The said action-slide is formed at its rear end with sfork 10, receiving the lower end of an actionslide link 11; Fig. 38, iormedst its upper end with an iuwardly-extending hub-like pivot 12, Fig. 39, by moons of which it is pivotally connected with the rear end of the rear link 13, Figs.'3, 8, 5), l0, and 1i, which is hung upon a heavy pivot 14, the ends of which have bearing in the opposite walls of the receiver or gun-fraine 8. Upon its iuncr face the link 11. is formed with a bearing-lug 15, Fig. 39, raving its upper edge concaved for coaction with the rounded lower edge 16 of therear nd of the rear link 13, whereby'strein is taken from the hub-like pivot 12 in closing the gun. F r this purpose the hole formed in the rear end of the rear link to receive the huh-like pivot 12 of the action-slide link 11 is made enough larger in dismetcr then the said pivot to permit the rounded edge 16 of the said link 13 to rest upon the lug l oi the said link 11, so that the strain is taken from the pivot 12, as stated, by he lifting of the concavedsurfsce of the lug 15 against the rounded edge 16 of the rear end of the rear link. The-forward link 17 is connected by a pivot 18 with the forward end of the rear link 13, while the forward end of the forward link is connected by means of s hol low bushing, like pivot 19, with the breechbolt 20, which is provided upon its opposite sides with guiding-ribs 2]., runningin grooves 22, Fig. 4, formed for their reception in the inner faces of the side walls of the receiver 8. The breech-bolt is thus confined to reeip-' rocation back and forth in a straight line. The recoil following the explosion of a, cartridge in the gun-barrel is taken by the forward and rear links when they are closed down'and in line, the rear link being at this time supported at its rear end by the actionslide link 11, which at this time stands verticslly under the rear end of the rear link, the rounded edge of which rests upon the homing-lug of the link 11. For the introduction of the breecl1-bolt into the gnndrame 8 the same is formed at its rear end with an opening 23, Fig. 2, which is located to the rear of the grooves 22 before mentioned and which permits the breech-bolt to be let down into the gun-frame and then moved forward into position. In order to increase thelength of the ribs 21 and so increase the bearing of the brceclrbolt, I provide the same with rib extensions 2%, located upon and extending forward from short studs 25, which are inserted into the opposite ends of the bushing-like pivot 19 aforesaid, Figs. 20, 21, and 22, the forward ends of the rib extensions 2i being formed with beveled fingers 26, which enter slots 27, formed in the rear ends of the ribs 21, as shown in Figs. 19 and 20, whereby the extensions 24: are held in place in line with.

the said ribs 21, of which they form rearward extensions. In this way the guiding-surfaces of the breech-bolt are increased nearly half without lengthening the gun-frame, which is undesirable. The bushing-like pivot 19 is made hollow for no other purpose than to receive the studs 25, carrying the rib extensions 24, which when the gun is assembled are always in line with the guiding-ribs 2l; which are formed with slots 27 for the reception of the beveled fingers 26, located at the ends of the said rib extensions fz l for the purpose of holding the said rib eitensions in Iiino with the said guiding-ribs of the bolt before the same is introduced into the frame of the gun.

In the breech-bolt l locate a firing-pin 28, formed with the usual stop-notch 29, the ends of which coact with the bushing-like pivotpiii 19 to limit the longitudinal movement of the pin, which is formed at its extreme end with two horizontellyhrrangcd retractingiugs 30, which are engaged by retracting shoulders 31, Figs. 17, 18, and 1S, formcdht the forward end of the forward link, which as it is lifted in the opening of the gun effects the retraction of the firing-pin through the medium of the said shoulders, as best shown in Fig. 18. l

A firing-pin striker 32, Figs. 3, 25, and 526, is mounted for longitudinal movementin the forward link 17 and provided at its rear end with a head 33, containing a shallow notch 34, the end walls of which engage, Fig. 3, with the pivot 18, uniting the rear and forward links, whereby the movement of the striker is limited. The said strikeris pushed back to correspond with the retraction of the firing-pin and during the elevation of the links by means of a cain-surface 5'5, Fig. 18, located upon the rear end of the bolt and working npon acam-surface 36,formed at the npper corner of the forward end of the said striker, Figs. 25 and The said striker and firing-pin constitute, in effect, a sectional firing-pin.

A hammer 37, .i ig. 5, is employed for giving the striker, and hence the firing-pin, its forward impulse. This hammer is pivoted upon a pin 38, mounted in the triggerguardplate 39. It is provided with an 'antifrictionroller 40, engaged by the forward end of a main or hammer spring 41, secured at its rear end by a screw to the rear end of the plate 39 and provided with the usual strain-screw 418 for varying the tension of the spring. The said hammer is furnished in its heel with a cooking-notch l4, receiving the forward end of a scar i5, controlled by a scar-spring 45, Figs. 33 and 34, and having a central opening 41 receiving the upper end of the trigger 47, which is hun upon a pin 48, mounted in the trigger guard-plate 39, and also constituting the pin upon which the sear 45 swings. The rear end of the sear 45 extends over the forward end of a sear-fly 49, Figs. 31 and 32, hung upon a pin 50 in the lower end of a safety-lever 51, Figs. 29 and 30, which is itself hung upon a pin 52, Fig. 3, mounted in the guard-plate 39. The said safety-lever eonstitutesa pivotal carrier for the sear-fly, which is moved back and forth as the lever is turned on its pivot. The said sear-fly 49 is formed with a stop-finger 53 and a shoulder 5%, which latter is engaged by a spiral spring 55, Figs. 8, 9, 10, and 11, located in the safety-lever and exerting a constant effort to press the forward end of the sear-fly downward upon the u pper edge of the trigger 47. The said safety-lever 51 is formed at its forward end with a beveled lug 56, entering a notch 57, formed in the lower edge of the action-slide 5, and having a beveled rear wall. a hub 58, through which the pin passes and which is provided at its opposite or lefthand end with a short arm 59, Fig. 30, the under face of which is engaged by a hollow plunger 60, containing a spring 61, and located in a plunger-chamber 62, formed in the trigger guard-plate 3 "This springsnorte- The said lever 51 is also formed with a constant effort to lift the beveled lug 56 of the safety-lever into the notch 57 of" the action-slide 5. The upper face of the arm 59 is located in. position for coaction with a cam-pin'63, projecting inwardly from the threaded hub 6% of a 'safetylock 65, formed with a wing-like finger-piece 66, as seen in Fig. 40. This safety-lock is located upon the left-hand wall of the gun-frame and turns upon its hub 64, which is entered into a suitable threaded opening formed in the said wall. Normally the lock is located in a Vertical position, in which it is held in any approved manner. When 'the lock is turned down into the horizontal position shown by Fig. 13 of the drawings, the cam-pin 63, acting upon the arm 59 of the safety-lever, rocks the same upon the pivot 52, whereby the forward end of the lever is depressed and the rear end of the lever elevated to bring its stop-finger 87 into engagement with a stopshoulder or abutment 68, formed very near the rear end of the action-slide 5, as shown in Fig. 13. YVhen the forward end of the safety-lever 51 is depressed, as dcscribed,-its

lower edge is engaged at about the point 69 with a laterally-projecting lug 70, Figs. 13

and 34, formed upon the sear, which is thus so firmly held that its forward end cannot be jarred outof the cooking-notch 4-1 of the hammcr. It will-thus be seen that when the safetylock is in use the action-bar is blocked against forward movement by the stop-finger of tho safety-lever and that the sear is held against rocking, movement by the forward end of the said lover, thus locking the gun against the, possibility of accidental firing. tVheu in the ordinary operation of the gun by thehandlc 2 the same is gripped and pushed forward,

the beveled rear wall of the notch 57 in the action-slide 5 engages with the beveled lug 56 of the safety-lever and rides over it, turning the lever on its pivot 52 and drawing the sear-fly 49 rearward] y away from the position in which its forward end forms a connection between the rear end of the scar and the upper edge of the trigger. Unless the forward end of the soar-lly is interposed between thb upper edge of the trigger and the rear end f the scar the latter cannot be operated by the former, because the trigger cannot be lifted high enough to engage with the scar for operating it. On the other hand, when the halldie 2 is drawn rearward for closing the gun the action-slide does not permit the safetylever to swing upward at its forward end for the reinscrtion of the-forward end of the scarfly between the scar and the trigger until the action-slide has com plcted its rearward movement, when it brings its notch 57 into such a position as to receive the beveled lug 56,

formed at the forward end of the lever, so

that it is impossible to fire the same has been fully closed.

For taking the power oihthe main or hammer spring 41 of the hammer, so as to permit gun until the thegnp to be opened oasil y, I employ a malnthe opening of the gun, the pawl is pressed downward, with the effect of depressing the mainspring 41 and taking its tension off the hammer 37, which is thus left free to be swung back by the bolt, to which it offers no substantial resistance. As the hammer is rocked backward by the rearward movement of the bolt its cocknotch 4.4 is brought into engagement. with the forward end of the sear, which snaps into it and holds the hammer cocked, L

the power of the mainspring ll being restored to the hammer on the closing movement of the gun, during which the pawl 71 is lifted.

The hammer 37 is formed at its lower end with a nose 74, which strikes against the rear surface of the rear wall 75 of the magazine, so as to prevent the hammer from moving too far forward when the gun is being opened and before the rear end of the bolt engages with the hammer to begin to push it rearward.

The gun. is provided with-a carrier 76, located in its magazine 77 and operated by a flat spring 78, bent upon itself and having its upper end loosely connected with the rear end of the carrier and having its lower end connected with a stirrup 79, the ends of which are swiveled in the cover of the magazine, as clearly shown in Fig. 16. This stirrup connection between the spring 78 and the cover provides play for the spring when it is being compressed by the depression of the carrier 76'. The forward end of the cover 80 is formed with a lug 81, which is inserted into a transverse notch 82, formed in the receiver 8, while the rear end of the cover is provided with a locking-finger 83, adapted to enter a notch 84, formed in the receiver, the said finger being normally held in the said notch by means of the upper end of a locking-dog 85, mounted upon a pin 86 in the trigger guard-plate 39. This dog is controlled by a spring 87 and projects suiiicicntly into the trigger-guard to be operated by moving the finger forward therein.

A yoke-shaped ejector 89, having arms 80 89, Figs. 27 and 28, is mounted in the receiver by means of two short screw-pivots 90, having wing like forward projections 91, which lie against the outer faces of the side walls of the receiver, the said pivots passing through the upwardly-turned ends of the said arms. The upper ends of the said arms terminate in lu s 02, which are engaged by the rear endsof tr e extension-ribs 24, already described, at points above the pivots 90, whereby the ejector is suddenly turned on those pivots for the elevation of its forward end, which is furnished with a toe 93, which engages with scope of my invention.

the body of the spent shell and projects it up wardthrough the loading and ejection open-- ing 9-1, formed in the top of the gun-frame.

Springs 05 are employed for restoring the ejector to its normal position. 1

.Having described the construction of my improved gun in detail, I will now proceed to briefly set forth its mode of operation. In order to open the gun, its handle2 is grasped and pushed directly forward, with the result of moving the action-slide 5 correspondingly forward. The'forward -movement of the.ac-

tion-slide 5 causes the forward movement of thelower end of the action-slideliuk 11, which draws down upon the rear end of the rear link 13, which is turned upon its pivot 14, whereby its forward end is lifted, with the effect of also retracting and lifting the forward link 17 and drawing the breech-bolt rearward intojts'full open position, as shown in Fig. 4. The gun is now ready to be charged with cartridges through the loadlng'and ejection opening 94. The cartridges may be loaded singly by hand or from a clip. The magazine having been loaded, the gun is closed by grasping the bandle 2 and drawing it rearward to the limit of its rearward movement, whereby the breechbolt is moved forward into its closed position,

in which it is held by the alinementof therear and forward links. The gun is now ready to be fired. After firing it the spent shell is extracted and another shell loaded into the gun-barrel by the forward and back movement of the handle. It seems unnecessary in this connection to describe the operation of all of the parts, inasmuch as their operation has been described in conjunction with the description of their detailed construction.

It is apparent that in carrying out my invention some changes from the construction herein shown and described may be made, and I would therefore have it understood that I do not limit myself to such details, but hold myself at liberty to make such deviations therefrom as fairly fall within the spirit and Thus in Fig. 431 have shown the use of a sliding fore-arm 96 for operating the action-slide 07, to the forward end of which it is attached, the said slide being formed with a slot 98, receiving a stop-pin 09,which limits the movement of the slide forv slide 101 is formed with a slot 107, receiving a stop-pin 108.

If desired, some other longitudinally-mow .able member of the action mechanism of the gun might be utilized for the operation of the safety dever, constituting a pivotal carrier for the sear-fly, than the ar tionyslide.
