- My invention relates to an improvement in breech-loading firearms, the object being to produce a compact, reliable, safe, durable and effective arm composed of comparatively few parts and not liable to derangement.
- my invention consists in a breech-loading magazine-firearm having a longitudinally-movable breech-bolt slide, and a breech-bolt actuated by the said slide in longitudinal and lateral movement, its rear end being moved laterally for locking it in its closed position and for unlocking it therefrom, and its forward end being moved laterally for coupling it with and uncoupling it from the forward end of the said slide, which has longitudinal movement independent of it.
- My invention further consists in the employment of a firing-pin mounted in a longitudinally-movable breech-bolt for connecting the same for lateral movement with the rear end of a longitudinally-nlovable breech-bolt slide.
- My invention further consists in a breechbolt slide provided at its rear end with an extension which engages with the rear end of a laterally-movable breech-bolt for pushing the same into its locked position.
- My invention further consists in a breechbolt constructed at its forward end with a head which coacts with fixed points in the frame for moving the said head and hence the bolt to the right and to the left for coupling the bolt with and uncoupling it from the 1011- gitudinally-movable slide by means of which it is moved back and fort-h.
- My invention further consists in a pivotal bell-crank lever located beneath a carrier and extending upward through the same into position to be engaged by a longitudinally-movable breech-bolt for .operating it and lifting the carrier.
- My invention further consists in a pivotal fender made independent of the carrier, and interposed between the same and an ejectionopening formed in one of the side walls of the frame.
- My invention further consists in a liftinglever pivotally mounted in the carrier and engaging with aportion of the frame and with the forward end of the trigger-plate for being operated to lift the cartridges as the carrier is lifted.
- My invention further consists in a cartridge-stop which is positively operated inward and outward through the medium of the action-bar.
- My invention further consists in a breechloading magazine-firearm having certain details of construction and combinations of parts, as will be hereinafter described, and pointed out in the claims.
- breech-bolt A located in the frame B of the gun and constructed and arranged so as to be not only reciprocated longitudinally back and forth the rein, but also so as to be laterally movable therein, its rear end having more range of lateral movement than its forward end.
- frameas used above I mean to include all of the gun-frame except the upper tang B and the lower tang .B thereof.
- the said breech-bolt is partially supported by the frame and partially supported by a breech-bolt slide 0, by means of which it is longitudinally reciproeated and through and by which it is moved laterally.
- the said breech-bolt slide is mounted in the frame, in which it is confined to longitudinal movement, being provided upon its upper and lower faces with longitudinal ribs 0 and 0', Figs. 6 and 11, which take into suitable grooves formed in the frame for their reception.
- To adapt the frame to receive the breech-bolt slide its right-hand side wall is cut away to form a longitudinal slot C, Fig. 1, which opens laterally into the chamber formed in the frame.
- the said handle is grasped and moved back and forth upon the magazine, whereby the breech-bolt slide 0, and hence the breech-bolt A, are actuated in longitudinal movement through the medium of the said action-bar connecting the breechbolt slide and the sliding supporting-handle.
- the firing-pin E is employed for loosely coupling the breech-bolt and slide together, the said pin being thereto furnished 'at its rear end with a lateral flange E, extending to the right and entering a deep horizontal slot C formed in the inner face of the said slide, Figs. 6, 7 and '8, which has an inward extension'C formed at its rear end, through which the said slot extends.
- the firing-pin is not located parallel with the longitudinal axis of the breech-bolt, but is inclined to the said axis, its flange Eemerging laterally from the rear portion of the breechb0lt, so as to enter the slot 0 in the said breech-bolt slide, and the rear end of its flange projecting beyond the rear end of the breech-bolt so as to enter 7 that portion of the said slot 0 contained in the said extension 0 of the breech-bolt slide.
- the firing-pin and breech-bolt are pivotally connected by means of a verticallyarranged coupling-pin E located in the bolt, and passing through an elongated slot E formed in the flange E of the pin, which is therefore free to move independently of the bolt within the limits of the length of the said slot E while the firing-pin and breech-bolt slide are connected by means of a verticallyarranged operating-stud e, located in the extreme rear end of the said flange E extending above and below the upper and lower faces thereof, and taking into two corresponding oppositely-arranged grooves (J C forwardly inclined with respect to the said slide, 10- ca d in the lateral extension 0, and leadingt of the upper and lower walls of the slot L, "The inner end of the said extension is shapeu to form an operating-bevel C, Fig.
- the said end of the extension is also shaped to form an inclined seat 0 upon which the said corner of the breech-bolt rests when the same is both closed and locked.
- the breech-bolt is thus moved longitudinally back and forth by the breech-bolt slide, while its rear end is moved from right to left directly by the said slide and from left to right by the firing-pin, which is thereto operated by the said slide.
- the rear end of the bolt also has a locking-face a
- the breech-bolt At its forward end the breech-bolt is enlarged to form a head A, which though but slightly narrower in width than the width of the upper portion of the receiver-chamber B is still enough narrower than the same to admit of a slight lateral movement of the said head, and hence the forward end of the bolt therein.
- the forward end of the breechbolt slide is constructed with a recess E, in which the said end of the bolt is in part supported.
- the forward end of thebolt is moved from left to right by means of a horizontally arranged outwardly projecting operatingshoulder A located upon the lefthand side of the said head and coacting with a similarly-arranged long guide-rib B projecting inwardly into the receiver-chamber B from the left-hand wall of the frame, the said rib being cut away at its forward end to form a clearance-space b for the shoulder A to enter and having its said endbeveled at b, as clearly shown in Figs. 7 and 8.
- the said head, and hence the forward end of the bolt is moved from right to left just as the bolt is passing into its fully-closed position by means of a bevel A formed at the upper right-hand corner of the said head, as shown in Fig.
- a coupling-shoulder A is formed in the righthand side of the head A of the bolt by notching the same, as clearly shown in Fig. 7, the said shoulder being engaged by the inner corner c, Fig. 8, of the extreme forward end of the breech-bolt slide.
- the bevel A formed on the right-hand side of the head A located at the forward end of the bolt clears the bevel B formed on the right-hand side of the forward end of the receiver-chamber B
- crating-bevel C located at the base of the for ward end of the extension 0 of the slide now engages with the beveled inner corner a of the rear end of the breech-bolt and moves the same laterally from right to left, whereby the locking-face a. at the said end of the breechbolt is swung in front of the locking-abutment B of the frame B and a portion of the bolt swung into the clearance openin g B formed in the said frame B in front of the said abutment.
- the operating-bevel Q passes the inner corner (I of the bolt and the inclined The opseat formed upon the inner end of the said extension is presented for engagement with the bolt, as shown in Fig. 7, and prevents the rear end of the bolt from moving from right to left, and hence out of its locked position.
- the bolt has longitudinal movement with the slide and that its rear end has lateral movement independent thereof for locking it in its closed position in the frame, and that its forward end has lateral movement independent of its rear end for coupling it with and uncoupling it from the forward end of the slide.
- the head A at the forward end of the breechbolt slide is furnished with an extractor F, located at the right, and an extractor F, located at the left, the latter co-operating with an abutment-block F against which the heads of the cartridgesabut, and which projects into the receiver-chamber B from the left-hand wall thereof, the said block virtually forming an ejector against which the cartridges are impinged as the breech-bolt is retracted with a cartridge in the grip of the extractors.
- the clearance-slot F formed in the left-hand side of the bolt is provided for clearing the abutment or ejector-block F when the breech-bolt is in its closed and locked position.
- the head of the breech-bolt is constructed on its lefthand side with a clearance-slot f, Fig. 13, for clearing the abutment or ejector-block F when the breech-bolt is drawn back into its open position.
- the extractors F and F may be of any approved construction.
- the forward end of the breechbolt is also provided with an operating-finger A depending from its head A, having its rear end undercut, as at (1 and beveled, as at a The function of this finger will be set forth later on.
- the carrier 11 of my improved gun is bifurcated at its rear end, Fig. 18, to receive the shank of the hammer I and to embrace the upright I of the trigger-plate I", Fig. 19, the carrier and hammer being hung upon a pivot H, passing through the said bifurcated rear end of the carrier, through the shank of the hammer, and through the said upright I of the trigger-plate 1 the forward end of which fits into the lower face of the rear end of the frame.
- the said carrier has a long clearance-opening H Fig. 18; formed in it to the rear of its longitudinal center for the upward passage through it of the upper arm J of a bell-crank or elbow lever, the lower arm J of which is located in alongitudinal groove 1 Fig.
- the said bell-crank lever is hung upon a horizontal pivot J 2 mounted, as shown in Fig. 19, in the forward end of the trigger-plate.
- the opening j, Fig. 4, formed in the said bell-crank lever for the reception of the pivot J is enough larger in diameter than the same to permit the lever to tip laterally from left to right against the tension of the spiral spring J mounted on the pin and interposed between the right-hand face of the lever and the adjacent wall of the recess 1 in the trigger-plate, as shown in Fig. 19.
- the said spring is provided for holding thelever in its normal or vertical position, from which it is deflected from left to right against the tension of the spring to permit the operating-finger A depending from the head A at the forward end of the breech-bolt to push it aside during the rearward movement of the said bolt, the left-hand face of the upper end of the upper arm J of the said bell-crank lever being beveled, as at j Fig. 19, to coact with the bevel a formed upon the right-hand corner of the rear end of the said depending finger, as shown in Fig.10.
- opening B formed in the right wall of the frame B when the cartridges are being transferred from the magazine to the barrel of the gun, and also for assisting in guiding the cartridges into the gun-barrel, I provide the carrier upon its right-hand side with a fender K,
- the breech-boltslide gradually closes the said ejection-opening B from the beginning to the end of its forward movement, when it completely closes the said opening, but the carrier is lifted at the beginning of the forward movement of the said slide, and hence before the said opening is closed to any extent thereby, wherefore the desirability of using the fender to prevent the accidental escape of the cartridges through the said opening before the slide has moved far enough forward to prevent their escape and for assisting in guiding the cartridges into the gun-barrel.
- the fender has still another function, for its upper edge is engaged by the slide as the same is closed, whereby the slide acts through the medium of the fender and the spring thereof in holding the carrier down in proper position and insures its being depressed when the slide is closed.
- I For the purpose of lifting the rear ends of the cartridges above the floor of the carrier and thus assisting in their introduction into the gun-barrel, I provide the carrier with a lifting-lever L, which is hung upon the horizontal arbor or pin K of the fender K. The lower portion of the rear end of this lever rests upon the forward end of the triggerplate I while the upper portion of its rear end will engage with the web B of the frame in such a manner that when the carrier and hence the lever are lifted, the latter will be turned on its center and its forward end raised above the floor of the carrier, with the effect of lifting the rear ends of the cartridges.
- the forward end of the carrier occupies the opening 13", formed in the bottom of the frame to permit the charging of the magazine with cartridges, which are fed into the frame through the said opening and pushed forward into the rear end of the magazine D one by one by hand, the carrier being forced upward each time so as to permit the cartridges to pass under it into the rear end of the magazine, which is furnished with a spring-actuated follower D of any approved construction.
- a cartridgestop M for preventing the cartridges from entering the frame from the magazine, except one at a time as required, I employ a cartridgestop M, Figs. 23, 24, and 25, pivotally secured at its rear end to a small plate M, rigidly secured by means of a screw on within the right wall of the frame, which is longitudinally recessed to receive the said stop and plate, which are pivoted together on the knuckle principle, and so as to limit the inward movement of the stop, which is constructed upon the inner face of its forward end with a stopshoulder m which, when in its operating position, engages the heads of the cartridges so as toprevent the same from emerging from the magazine.
- the outer face of the free forward end of the stop is furnished with an outwardly-projecting operating-arm m having a depending finger m the ends of the inner face whereof are outwardly beveled, as seen in Fig. 25.
- the said arm projects outward through an opening m Figs.
- a guiding-lug M Figs. 20 and 23 which is located on the right hand of the frame B at the extreme forward end thereof and enters the straight portion of the long groove m formed in the inner face of the action-bar, which is thereby guided and prevented from being moved up or down, except as it is disengaged from the said lug.
- FIG. 1 Another feature of my invention is the utilization of the magazine as a lever for screwing the barrel into the frame and unscrewing it therefrom, and also as a wedge for tightening the barrel in the frame B.
- the magazine D is pivotally connected by means of a screw-stud D with a heavy lug D depending from the lower face of the gun-barrel G.
- the rear end of the magazine is furnished with a head d, having its rear or outer face beveled or inclined, as at d, the said head being adapted to be entered into a deep recess (P, Fig. 5, formed to receive it in the lower face of the forward end of the frame and having its rear wall forwardly inclined.
- P deep recess
- the breechbolt is fully opened and the rear end of the magazine disconnected from the frame, so that it may be used as a handle-lever.
- the gun-barrel is then inserted into the frame with the magazine turned one-quarter to the left and'turned to the right as far as it will go, using the magazine as a lever for turning it.
- the follower D of the magazine is pushed'inward even with the rear end thereof and the magazine closed in, so that its head (I will enter the recess (1 in the frame. Vhen the said head has been pushed home in the detailed description.
- the locking-plate D is pushed forward to'engage with the lower edge of the head for holding the magazine in its closed position.
- the said locking-plate, Figs. 16 and 17, is provided with a central slot, permitting it to be moved back and forth, and is connected with the frame by means of a screw (1
- To remove the barrel from the frame the plate D is pushed back so as to free the rear end of the magazine, which is then turned down so as to formalever, by means of which the barrel is turned one-quarter turn from right to left, after which the barrel may be removed.
- a safety-catch N mounted in the web or bridge B of the frame 13 at a point just in front of the hammer, and slightly inclined rearward, its upper end being adapted to take into a notch N formed transversely in the extreme rear end of the extension 0 of the breech-bolt slide. 0, and its lower end being engaged with a spring N secured to the upper tang B of the gun-frame, which alsoineludes the frame B and the lower tang B.
- this catch is furnished with a rearwardly-projecting finger N which is engaged by the hammer I, when the same is thrown forward, in such a manner as to depress the catch and, clear its upper end from the notch N in the breech-bolt slide, but the hammer depresses the catch in the manner set forth only when in its closed position, so that when it is half-cocked or full-cocked the breech-bolt slide and breech-bolt are firmly held in their locked positions by the catch.
- the hammer hen the hammer is down, however, as it will be after the firing of the gun, it holds the catch down, so that the same does not interfere with the action of thebreech-bolt slide in automatically throwing the hammer back to its full-cocked position.
- the catch thus prevents the manipulation of the gun except under certain conditions, which are ordinarily present only when the same has-been fired or the hammer let down.
- the trigger O, guard O, hammer-spring O and otherinstrumentalities not set forth may be considered to be of any approved construction.
- a breech-loading magazine gun the combination with a frame having a chamber formed in it and also having one of its side walls cut away to form a longitudinal slot which opens laterally into the said chamber, of a longitudinally movable breech-bolt slide located in the said slot and movable back and forth therein, and a breech-bolt located in the said chamber and actuated by the said slide in longitudinal and lateral movement, and connected at its rear end therewith, its rear end being moved laterally for engaging it with the frame to lock it in its closed position and for disengaging it from the frame to unlock it, and its forward end which is disconnected from the slide, being moved laterally for coupling it with and uncoupling it from the forward end of the slide which has longitudinal movement independent of it, substantially as described.

My invention relates to an improvement in breech-loading firearms, the object being to produce a compact, reliable, safe, durable and effective arm composed of comparatively few parts and not liable to derangement.
With these ends in view my invention consists in a breech-loading magazine-firearm having a longitudinally-movable breech-bolt slide, and a breech-bolt actuated by the said slide in longitudinal and lateral movement, its rear end being moved laterally for locking it in its closed position and for unlocking it therefrom, and its forward end being moved laterally for coupling it with and uncoupling it from the forward end of the said slide, which has longitudinal movement independent of it.
My invention further consists in the employment of a firing-pin mounted in a longitudinally-movable breech-bolt for connecting the same for lateral movement with the rear end of a longitudinally-nlovable breech-bolt slide.
My invention further consists in a breechbolt slide provided at its rear end with an extension which engages with the rear end of a laterally-movable breech-bolt for pushing the same into its locked position.
My invention further consists in a breechbolt constructed at its forward end with a head which coacts with fixed points in the frame for moving the said head and hence the bolt to the right and to the left for coupling the bolt with and uncoupling it from the 1011- gitudinally-movable slide by means of which it is moved back and fort-h.
My invention further consists in a pivotal bell-crank lever located beneath a carrier and extending upward through the same into position to be engaged by a longitudinally-movable breech-bolt for .operating it and lifting the carrier.
My invention further consists in a pivotal fender made independent of the carrier, and interposed between the same and an ejectionopening formed in one of the side walls of the frame. My invention further consists in a liftinglever pivotally mounted in the carrier and engaging with aportion of the frame and with the forward end of the trigger-plate for being operated to lift the cartridges as the carrier is lifted.
My invention further consists in a cartridge-stop which is positively operated inward and outward through the medium of the action-bar.
My invention further consists in a breechloading magazine-firearm having certain details of construction and combinations of parts, as will be hereinafter described, and pointed out in the claims.
In carrying out my invention, as herein shown, I employ a breech-bolt A, located in the frame B of the gun and constructed and arranged so as to be not only reciprocated longitudinally back and forth the rein, but also so as to be laterally movable therein, its rear end having more range of lateral movement than its forward end. By the term frameas used above I mean to include all of the gun-frame except the upper tang B and the lower tang .B thereof. The said breech-bolt is partially supported by the frame and partially supported by a breech-bolt slide 0, by means of which it is longitudinally reciproeated and through and by which it is moved laterally. The said breech-bolt slide is mounted in the frame, in which it is confined to longitudinal movement, being provided upon its upper and lower faces with longitudinal ribs 0 and 0', Figs. 6 and 11, which take into suitable grooves formed in the frame for their reception. To adapt the frame to receive the breech-bolt slide its right-hand side wall is cut away to form a longitudinal slot C, Fig. 1, which opens laterally into the chamber formed in the frame.
An action-bar 0, connected at its rear end with the forward end of the breech-bolt slide, is provided upon the inner face of its forward end with a vertically-arranged dovetail rib 0 Fig. 3, taking into a dovetail groove D, formed in a lateral enlargement of the inner end of a metal bushing or wearing-sleeve D, secured within the inner end of a sliding supporting-handle D arranged to slide back and forth upon the tubular magazine D To operate the breech-bolt, the said handle is grasped and moved back and forth upon the magazine, whereby the breech-bolt slide 0, and hence the breech-bolt A, are actuated in longitudinal movement through the medium of the said action-bar connecting the breechbolt slide and the sliding supporting-handle.
The firing-pin E is employed for loosely coupling the breech-bolt and slide together, the said pin being thereto furnished 'at its rear end with a lateral flange E, extending to the right and entering a deep horizontal slot C formed in the inner face of the said slide, Figs. 6, 7 and '8, which has an inward extension'C formed at its rear end, through which the said slot extends.
The firing-pin, it will be observed by reference to Figs. 7 and 8 of the drawings, is not located parallel with the longitudinal axis of the breech-bolt, but is inclined to the said axis, its flange Eemerging laterally from the rear portion of the breechb0lt, so as to enter the slot 0 in the said breech-bolt slide, and the rear end of its flange projecting beyond the rear end of the breech-bolt so as to enter 7 that portion of the said slot 0 contained in the said extension 0 of the breech-bolt slide.
The firing-pin and breech-bolt are pivotally connected by means of a verticallyarranged coupling-pin E located in the bolt, and passing through an elongated slot E formed in the flange E of the pin, which is therefore free to move independently of the bolt within the limits of the length of the said slot E while the firing-pin and breech-bolt slide are connected by means of a verticallyarranged operating-stud e, located in the extreme rear end of the said flange E extending above and below the upper and lower faces thereof, and taking into two corresponding oppositely-arranged grooves (J C forwardly inclined with respect to the said slide, 10- ca d in the lateral extension 0, and leadingt of the upper and lower walls of the slot L, "The inner end of the said extension is shapeu to form an operating-bevel C, Fig. 10, which coacts with the beveled inner corner a of the rear end of the breech-bolt to force the same from right to left for looking it in its closed position. The said end of the extension is also shaped to form an inclined seat 0 upon which the said corner of the breech-bolt rests when the same is both closed and locked. The breech-bolt is thus moved longitudinally back and forth by the breech-bolt slide, while its rear end is moved from right to left directly by the said slide and from left to right by the firing-pin, which is thereto operated by the said slide. The rear end of the bolt also has a locking-face a,
which, when the said end of the bolt is swung from right to left, coacts with a locking-abutment B, formed in the left-hand side of the rear end of the frame, also having a clearance-opening B formed in it at a point di' rectly in front of the said abutment, as clearly shown in Figs. 2, 7 and 8.
At its forward end the breech-bolt is enlarged to form a head A, which though but slightly narrower in width than the width of the upper portion of the receiver-chamber B is still enough narrower than the same to admit of a slight lateral movement of the said head, and hence the forward end of the bolt therein. To receive the right-hand side. of the said head the forward end of the breechbolt slide is constructed with a recess E, in which the said end of the bolt is in part supported. The forward end of thebolt is moved from left to right by means of a horizontally arranged outwardly projecting operatingshoulder A located upon the lefthand side of the said head and coacting with a similarly-arranged long guide-rib B projecting inwardly into the receiver-chamber B from the left-hand wall of the frame, the said rib being cut away at its forward end to form a clearance-space b for the shoulder A to enter and having its said endbeveled at b, as clearly shown in Figs. 7 and 8. The said head, and hence the forward end of the bolt, is moved from right to left just as the bolt is passing into its fully-closed position by means of a bevel A formed at the upper right-hand corner of the said head, as shown in Fig. 14, and by means of a coacting bevel 13 formed in the frame at the upper right-hand corner of the forward end of the receiver-chamber B as shown in Fig. 7. The said head is moved from right to left and left to right by means of the instrumentalities described, for the purpose of disconnecting the forward end of the breech-bolt from and connecting the said end of the bolt with the forward end of the breech-bolt slide. For the purpose of connecting the forward end of the breech-bolt with the forward end of the breech'bolt slide a coupling-shoulder A is formed in the righthand side of the head A of the bolt by notching the same, as clearly shown in Fig. 7, the said shoulder being engaged by the inner corner c, Fig. 8, of the extreme forward end of the breech-bolt slide.
In illustration of the operation of the breechbolt slide and breech-bolt let it be supposed that both are in their closed and locked positions. Now when the said slide begins to move back, the inclined forward walls of the grooves G C in the extension C at its rear end will engage with the vertically-arranged operating-stud e, located in the flange'E of the firing-pin E, and draw the same back without stirring the bolt until the forward end wall of the elongated slot E in the flange E of the firing-pin brings up against the coupling-pin E? in the bolt, the rear end of which from this moment begins to move from left to right under the drawing action of the firing-pin,which is correspondingly moved by the drawing action of the forwardly-inclined forward walls of the said grooves C C before mentioned. The breech-bolt is thus unlocked by the swinging of the locking-face a at its rear end away from the locking-abutment B, formed in the left-hand side of the rear end of the frame. The breech-bolt having thus been moved at its rear end from left to right and unlocked is now free to be moved back into its open position by the breech-bolt slide of the straight longitudinal movement whereof it then partakes. Just as soon as the slide begins to move back, the bevel A formed on the right-hand side of the head A located at the forward end of the bolt clears the bevel B formed on the right-hand side of the forward end of the receiver-chamber B As soon as these bevels have cleared each other the rear end of the operating-shoulder A located on the lefthand side of the said head, engages with the bevel 1) formed at the forward end of the guide-rib I? projecting into the left-hand side of the said receiver-chamber. The breechbolt continuing to move'rearward, the said shoulder rides upon the said bevel, whereby the forward end of the bolt is shifted from left to right, whereby its coupling-shoulder A is moved directly in front of the inner corner c of the extreme forward end of the breechbolt slide. The bolt now moves rearward with the said slide, its forward end being maintained in its deflection to the right by means of the guide-rib B acting on the shoulder A The bolt and slide thus move into their fully-open positions. At the beginning of the closing movement of the bolt and slide the latter moves forward alone at first, until the corner 0 of its forward end abuts against the coupling-shoulder A before mentioned, after which the bolt and slide move steadily forward until the bevel A of the bolt engages with the bevel B of the frame B, with the effect of shifting the forward end of the bolt from right to left, which is permitted by the clearance-space I) provided for the shoulder A in front of the guide-rib B the forward end of which the said shoulder has by this time passed. The described lateral movement of the forward end of the bolt from right to left is just sufiicient to clear the couplingshoulder A of the bolt from the forward end of the breech-bolt slide, which has now moved the bolt forward as far as it will go. crating-bevel C located at the base of the for ward end of the extension 0 of the slide now engages with the beveled inner corner a of the rear end of the breech-bolt and moves the same laterally from right to left, whereby the locking-face a. at the said end of the breechbolt is swung in front of the locking-abutment B of the frame B and a portion of the bolt swung into the clearance openin g B formed in the said frame B in front of the said abutment. Then, just as the bolt is coming into its fullyclosed position, the operating-bevel Q passes the inner corner (I of the bolt and the inclined The opseat formed upon the inner end of the said extension is presented for engagement with the bolt, as shown in Fig. 7, and prevents the rear end of the bolt from moving from right to left, and hence out of its locked position. It will thus be seen that the bolt has longitudinal movement with the slide and that its rear end has lateral movement independent thereof for locking it in its closed position in the frame, and that its forward end has lateral movement independent of its rear end for coupling it with and uncoupling it from the forward end of the slide.
The head A at the forward end of the breechbolt slide is furnished with an extractor F, located at the right, and an extractor F, located at the left, the latter co-operating with an abutment-block F against which the heads of the cartridgesabut, and which projects into the receiver-chamber B from the left-hand wall thereof, the said block virtually forming an ejector against which the cartridges are impinged as the breech-bolt is retracted with a cartridge in the grip of the extractors. The clearance-slot F formed in the left-hand side of the bolt is provided for clearing the abutment or ejector-block F when the breech-bolt is in its closed and locked position. The head of the breech-bolt is constructed on its lefthand side with a clearance-slot f, Fig. 13, for clearing the abutment or ejector-block F when the breech-bolt is drawn back into its open position. I may mention here that the extractors F and F may be of any approved construction. The forward end of the breechbolt is also provided with an operating-finger A depending from its head A, having its rear end undercut, as at (1 and beveled, as at a The function of this finger will be set forth later on.
The carrier 11 of my improved gun is bifurcated at its rear end, Fig. 18, to receive the shank of the hammer I and to embrace the upright I of the trigger-plate I", Fig. 19, the carrier and hammer being hung upon a pivot H, passing through the said bifurcated rear end of the carrier, through the shank of the hammer, and through the said upright I of the trigger-plate 1 the forward end of which fits into the lower face of the rear end of the frame. The said carrier has a long clearance-opening H Fig. 18; formed in it to the rear of its longitudinal center for the upward passage through it of the upper arm J of a bell-crank or elbow lever, the lower arm J of which is located in alongitudinal groove 1 Fig. 19, formed in the trigger-plate, and engages with the under face of a web or bridge ll, located at the rear end of the carrier, as seen in Fig. 18. The said bell-crank lever is hung upon a horizontal pivot J 2 mounted, as shown in Fig. 19, in the forward end of the trigger-plate. The opening j, Fig. 4, formed in the said bell-crank lever for the reception of the pivot J is enough larger in diameter than the same to permit the lever to tip laterally from left to right against the tension of the spiral spring J mounted on the pin and interposed between the right-hand face of the lever and the adjacent wall of the recess 1 in the trigger-plate, as shown in Fig. 19. The said spring is provided for holding thelever in its normal or vertical position, from which it is deflected from left to right against the tension of the spring to permit the operating-finger A depending from the head A at the forward end of the breech-bolt to push it aside during the rearward movement of the said bolt, the left-hand face of the upper end of the upper arm J of the said bell-crank lever being beveled, as at j Fig. 19, to coact with the bevel a formed upon the right-hand corner of the rear end of the said depending finger, as shown in Fig.10.
\Vhen the breech-bolt moves forward, the square forward end of the operating-finger A abuts against the square rear edge of the upper arm J of the said bell-crank lever, which Itwill be understood that the carrier is lifted as described at the beginning of the forward movement of the breech-bolt, and is maintained in its elevated position until the breech-bolt has entered the forward end of the cartridge lifted by the carrier into the gun-barrel, after which the operating-finger A of the breech-bolt passes forward of and clears the upper arm J of the said bell-crank lever and thus permits the carrier to drop back into its depressed position of readiness to receive another cartridge from the magazine. "When, on the other hand, the breechbolt is moving back into its open position the bevel a of its depending finger A engages with the bevel j of the upper arm J of the bell-crank lever, which yields laterally, tipping from left to right against the tension of the spring J which immediately rights the lever after the said operating-finger has passed by and to the rear of it and thereafter holds it in its righted position, in which the square forward edge of the said finger A engages with the square rear edge of the said arm, when the breech-bolt is again moved forward.
For the purpose of preventing the chance escape of the cartridges from the ejection-. opening B formed in the right wall of the frame B, when the cartridges are being transferred from the magazine to the barrel of the gun, and also for assisting in guiding the cartridges into the gun-barrel, I provide the carrier upon its right-hand side with a fender K,
consisting of a vertically-arranged thin plate of metal rigidly secured at its inner end to a horizontal arbor K, the ends of which are 3' ournaled in the carrier and which is provided with a short forwardly-projecting finger K which engages with the free inner end of a flat sheet-metal spring K the forward end of which is rigidly secured to the bottom of the forward end of the carrier, with which the fender is thus pivotally and yieldingly conconnected, so as to stand above the bottom of the forward end thereof. The breech-boltslide gradually closes the said ejection-opening B from the beginning to the end of its forward movement, when it completely closes the said opening, but the carrier is lifted at the beginning of the forward movement of the said slide, and hence before the said opening is closed to any extent thereby, wherefore the desirability of using the fender to prevent the accidental escape of the cartridges through the said opening before the slide has moved far enough forward to prevent their escape and for assisting in guiding the cartridges into the gun-barrel. The fender has still another function, for its upper edge is engaged by the slide as the same is closed, whereby the slide acts through the medium of the fender and the spring thereof in holding the carrier down in proper position and insures its being depressed when the slide is closed.
For the purpose of lifting the rear ends of the cartridges above the floor of the carrier and thus assisting in their introduction into the gun-barrel, I provide the carrier with a lifting-lever L, which is hung upon the horizontal arbor or pin K of the fender K. The lower portion of the rear end of this lever rests upon the forward end of the triggerplate I while the upper portion of its rear end will engage with the web B of the frame in such a manner that when the carrier and hence the lever are lifted, the latter will be turned on its center and its forward end raised above the floor of the carrier, with the effect of lifting the rear ends of the cartridges. \Vhen in its depressed or normal position, the forward end of the carrier occupies the opening 13", formed in the bottom of the frame to permit the charging of the magazine with cartridges, which are fed into the frame through the said opening and pushed forward into the rear end of the magazine D one by one by hand, the carrier being forced upward each time so as to permit the cartridges to pass under it into the rear end of the magazine, which is furnished with a spring-actuated follower D of any approved construction.
For preventing the cartridges from entering the frame from the magazine, except one at a time as required, I employ a cartridgestop M, Figs. 23, 24, and 25, pivotally secured at its rear end to a small plate M, rigidly secured by means of a screw on within the right wall of the frame, which is longitudinally recessed to receive the said stop and plate, which are pivoted together on the knuckle principle, and so as to limit the inward movement of the stop, which is constructed upon the inner face of its forward end with a stopshoulder m which, when in its operating position, engages the heads of the cartridges so as toprevent the same from emerging from the magazine. The outer face of the free forward end of the stop is furnished with an outwardly-projecting operating-arm m having a depending finger m the ends of the inner face whereof are outwardly beveled, as seen in Fig. 25. The said arm projects outward through an opening m Figs. 20 and 22, formed in the right wall of the frame and into a long groove m formed in the inner face of the action-bar C, and curved outwardly at its rear end,as at m, to clear a draw-flange m the outer face of the forward end of which is beveled, as at m and which stands in the plane of the long groove m Supposing the actionbar to be in its fully-closed position, the depending finger m of the arm m of the stop will be located in the outwardly-curved portion m of the groove m in the actionbar, as
shown in Fig. 23. Now when the said bar is moved rearward the curved forward end of the curved portion m of the groove will force the finger m inward, and hence the arm m whereby the stop will be caused to move inward into the path of the cartridges, as shown in Fig. 24, and will be retained in this position by the engagement of the said finger with the outer wall of the straight portion of the groove m in the bar. hen, on the other hand, in the closing movement of the bar the same approaches its closed position, the bevel m at the forward end of the draw-flange at will engage with the beveled inner face of the rear end of the finger m and draw the said finger outward into the curved portion of the groove and outside of the said draw-flange, whereby the stop will be positively swung out of the path of the cartridges as they emerge from the magazine. Then when the bar is moved rearward the curved forward end of the curved portion m of the groove will force the stop inward again. It will thus be seen that I do not depend upon the action of a spring for either movement of the stop, but that under my construction the stop is positively moved into its operative position and positively moved into its retired position, securing perfect reliability in the operation of the stop.
For preventing the breech-bolt slide from being deflected up or down I provide the frame with a guiding-lug M Figs. 20 and 23, which is located on the right hand of the frame B at the extreme forward end thereof and enters the straight portion of the long groove m formed in the inner face of the action-bar, which is thereby guided and prevented from being moved up or down, except as it is disengaged from the said lug.
Another feature of my invention is the utilization of the magazine as a lever for screwing the barrel into the frame and unscrewing it therefrom, and also as a wedge for tightening the barrel in the frame B. The magazine D is pivotally connected by means of a screw-stud D with a heavy lug D depending from the lower face of the gun-barrel G. The rear end of the magazine is furnished with a head d, having its rear or outer face beveled or inclined, as at d, the said head being adapted to be entered into a deep recess (P, Fig. 5, formed to receive it in the lower face of the forward end of the frame and having its rear wall forwardly inclined. To secure the barrel to the frame the breechbolt is fully opened and the rear end of the magazine disconnected from the frame, so that it may be used as a handle-lever. The gun-barrel is then inserted into the frame with the magazine turned one-quarter to the left and'turned to the right as far as it will go, using the magazine as a lever for turning it. Then the follower D of the magazine is pushed'inward even with the rear end thereof and the magazine closed in, so that its head (I will enter the recess (1 in the frame. Vhen the said head has been pushed home in the detailed description.
said recess, the locking-plate D is pushed forward to'engage with the lower edge of the head for holding the magazine in its closed position. The said locking-plate, Figs. 16 and 17, is provided with a central slot, permitting it to be moved back and forth, and is connected with the frame by means of a screw (1 To remove the barrel from the frame the plate D is pushed back so as to free the rear end of the magazine, which is then turned down so as to formalever, by means of which the barrel is turned one-quarter turn from right to left, after which the barrel may be removed. By the construction just above described the operation of removing and applying the barrel is made very easy, while at the same time the connection of the barrel with the frame is made exceedingly firm.
The turning of the barrel a quarter-turn in one direction for connecting it with the frame and a quarter-turn in the opposite direction for disconnecting it therefrom, as above described, assumes that it as well as the frame has suitable interrupted screw-threads which are too well known to require illustration or The magazine would have the same value as a lever, however, if the barrel and frame had continuous threads requiring the complete rotation of the barrel.
Forlocking the breech-bolt slide, and hence the breech-bolt, intheir closed positions I employ a safety-catch N, mounted in the web or bridge B of the frame 13 at a point just in front of the hammer, and slightly inclined rearward, its upper end being adapted to take into a notch N formed transversely in the extreme rear end of the extension 0 of the breech-bolt slide. 0, and its lower end being engaged with a spring N secured to the upper tang B of the gun-frame, which alsoineludes the frame B and the lower tang B.
The upper end of this catch is furnished with a rearwardly-projecting finger N which is engaged by the hammer I, when the same is thrown forward, in such a manner as to depress the catch and, clear its upper end from the notch N in the breech-bolt slide, but the hammer depresses the catch in the manner set forth only when in its closed position, so that when it is half-cocked or full-cocked the breech-bolt slide and breech-bolt are firmly held in their locked positions by the catch. hen the hammer is down, however, as it will be after the firing of the gun, it holds the catch down, so that the same does not interfere with the action of thebreech-bolt slide in automatically throwing the hammer back to its full-cocked position. The catch thus prevents the manipulation of the gun except under certain conditions, which are ordinarily present only when the same has-been fired or the hammer let down.
The trigger O, guard O, hammer-spring O and otherinstrumentalities not set forth may be considered to be of any approved construction.
Inasmuch as the operation of the gun has been sofully set forth ,in connection with the description of its construction I deem it unnecessary to describe its operation further.
It is apparent that in carrying out my invention some changes in the construction herein shown and described may be made, and I would therefore have it understood that I do not limit myself to the exact construction herein set forth, but hold myself at liberty to make such changes and alterations as fairly fall within the spirit-and scope of my invention.
Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
