Anulication led April 25, 1906. Serial No. 313,567.

To a/ZZ whom, it wwf/y concern:

Be it known that I, CARL HANSEN, a subject of the King of Denmark, residing at Johnson, in the county of Orange and State of,N ew York, have invented certain new and useful Improvements in Magazine-Guns, of which the following is a specification, such as will enable those skilled in the art to which it appertains to make and use the same.

My invention relates to breech-loading semi-automatic magazine-firearms.

The purpose of my invention is to produce a strong, durable, and accurate firearm which is simple, cheap, and easily manufactured, embodying certain details of improvements in connection with the construction, operation, and combination of the operating parts of the firearm.

One obj ect of my invention is to facilitate the operation of handling the ammunition in charging the gun and the movements required in such operation by a direct, simple, and positive acting and working combination of the constructive mechanical features which enter into such operation.

A further object of my invention is to provide a gun which is especially accurate and safe for long-range shooting and in Whi ch the frame and the therewith-connected movable parts will sustain. the strain of heavy and continuous firing and distribute such strain equally on all resisting parts of the gun, which latter, while light of weight and symmetrical in form, is provided in all its operative parts with abundant strength to resist any destructive strain that may be placed upon it in its manipulation as a firearm..

All the details of improvements embodied in my invention are more fully set forth in the accompanying drawings and specification, and various modifications of the same *may be made without departing from the spirit of my invention., and I do not limit myself to the exact form as illustrated and described.

In the accompanying drawings, Figure 1 is an outside view of the receiver, magazine, and other operative parts, showing the handle in section and the gun ready for firing; Fig. 2, a partial side view of the breech-bolt lock, the handle being shown in dotted lines and thrown up into the first position for loading the gun Fig. 3, a sectional view of the magazine, magazine stop-lock, and accompanying parts Fig. 4, a central vertical sectional view of the entire loading and firing mechanism Fig. 5, a transverse vertical sectional view on the line of Fig. 3; Fig. 6, a similar view on the line y y of Fig. 3; Fig. 7, a similar view on the line 2 z of Fig. 3; Fig. S, a partial horizontal sectional view on the axis of the iiring-pin Fig. 9, a bottom view of the bolt-head, partly in section, Fig. 10, an end view of the bolt-head, showing the extractor and the ejector; Fig. 1 1, a view similar to Fig. 6, illustrating the same parts, but with the cartridge-stop springs opened to permit the insertion of cartridges into the magazine, and Fig. 12, a detail view showing the barrel of the firearm inserted into the outer end of the receiver and illustrating the shell-extractor head positioned in a recess of the barrel.

Similar characters of reference refer to similar parts throughout the drawings and the specification.

The receiver 2 forms an integral part with the main frame 1, to which in the usual manner is attached the stock S, as shown in Fig. 4. The forward end 3 of the receiver 2 1s provided with an internal screw-thread for the purpose of attaching thereto the barrel 106 of the gun, as seen in Fig. 12. The receiver 2 has depending therefrom the magazine 4, pivotally comiected to the lug 42, which latter is located beneath the most forward end 3 of the receiver 2. The magazine 4 is incased by a magazine-lever 5, which likewise is pivotally connected to the lug 42. A pivot-pin 43 secures in place both the magazine and the magazine-lever. A vertically-downward-swmging motion can be imparted to the magazine-lever 5, and the same can be brought to the position shown in Fig. 4 by bearing with the finger upon the thumb-piece 50, which latter forms a part of a double-arm lever and is fastened, by means of pivot-pin 49, to the rear end 47 of the frame of the magazine-lever 5. The thumbpiece-lever arm 50 is provided with a longer arm 48, placed at right angle to the shorter lever 50, and is movably seated in the slot 53 on the rearward end 47 of the magazine-lever 5. It carries on its upper extension the catch-lock 52, andthe lever-arm 48, with its catch-lock 52, is normally held in a closed position by means of a flat tension-spring 51, as shown in Fig. 3 of the drawings, and the catch 52 in this position engages with the stationary lock 62., which latter is secured in position to the main frame 1 of the receiver 2 by means of set-screw 3 This set-screw incidentally serves to hold in place the fiat IOO IIO

tension scar-spring 87. A downward pressure exerted against the thumb-piece 50 will release the catch 52 from the lock 62 and will enable the operator to carry the magazinelever 5 downwardly and bring the same from the position shown in Fig. 3 to the position illustrated in Fig. 4 of the drawings, n the magazine-lever 5 turning thereby upon its pivot-point 48, as heretofore described.

The magazine 4, which is partly incased by the magazine-lever 5 and with the' latter also partly enters into the under side of receiver 2, contains the cartridge-carrier 76, which is movable therein and which is seated upon the carrier-spring 78. @ne terminal 84 of the spring 78 is secured to the inner end wall 72 of the magazine 4 by means of the set-screws 73, while the other terminal 79 has an upward-extending catch-point, against which a corresponding downward catch-lug 80` of the cartridge-carrier 76 bears and makes contact connection therewith. rlhe carrier 76 has an outwardly-placed pin 77, which extends through segmental slots 82 in the magazine 4 and through similar segmental slots 44 in the magazine-lever 5, it being understood that the pin 77 passes through the carrier, extends on either side thereof, and engages on either side with the slots 44 and 82. These slots are described with a true arc with the pivotpin 43 as center, and the pin 77 can freely travel within these slots whenever the carrier 76 is lifted upwardly by the action of the carrier-spring 78 in order to feed. the cartridges C upwardly into operative position and in line with the axis of the bore of the barrel and the axis of the firing-pin. If, however, the magazine-lever 5 is brought downward toward its extreme lowest position, as shown in Fig. 4 of the drawings, the upper terminal 107 of the slot 44 will engage with the projecting pin 77 and carry the cartridge-carrier 76 downward until it comes to rest upon the .bottom of the magazine. The lower terminal of the magazine-slot 82 has a horizontal continuation, as shown at 81, and the pin 77 on the carrier 76 is forced into this horizontal slot 81 by means of the hook 79 of the carrier-spring 78 pulling forwardly against the lug 80 of carrier v7 6, whereby the latter is held locked until released by the upward motion of the magazine-lever 5, in which case the cam-shaped lower terminal 45 of the segmental slot 44 of the lever 5 will force the carrier-pin 77 out of the locked position at 81.

A continued downward movement of the magazine-lever 5 will cause the magazine 4 to swing downwardly to a limited extent upon its pivot-pin 48, and in doing so a dovetail-shaped cam 65 at the upper extension of the rearward end 72 of the magazine-casing, and which forms an integral part therewith, engages with the cartridge-stop-spring lugs 66 and presses the latter sidewise into receiving-recesses 98, prepared in the inner walls of the receiver 2, as shown in Fig. 11 of the drawings. Fastened to the rear end of the dovetail-shaped cam 65 and rearwardly extending therefrom is a pin 70, which engages into a vertical slot 71 of thereceiverframe 2 and acts as a limit-stop for the vertical upward and downward swinging motion of the magazine, and the downward vertical motion of the lever 5 is also limited by means of this pin 70. These cartridge-stop-spring lugs 66, as will be seen more clearly in Fig. 8 of the drawings, form part of two flat springs 67, which by means of pins 69 are positioned against the inner side walls of the receiver 2, are fastened by meansl of these pins to the forward end of the receiver, and extend backwardly the entire length of thesame, with the aforementioned lugs 66 on the rearmost end thereof, and both springs 66 normally press inwardly. These springs 67 have iiat horizontal inwardly-extending projections or wings 68, which latter when the springs 67 are in their normal position overlap the upper cartridge C in the magazine, as shown in Fig. 3 of drawings, and hold the same and the series of cartridges below the same in a securely-locked position in' the magazine. If, however, the springs 67 are pressed outwardly into the recesses 98, as aforedescribed, by reason of the dovetail shaped cam 65 pressing against the triangular springcams 66, caused by a downward motion of the magazine-lever and the magazine, then the upper cartridge is free to be entered into the receiver 2 by the lifting action of carrierspring 78.

The forward end of the magazine is closed by the wall 86, while in the rearward end of the same and outwardly of its casing-wall 72 is located the magazine-stop 64, which is designed to lift the magazine 4, and thereby 1elease the cartridge-stop springs 67. As heretofore described, .the upper extension of the rearward end of the magazine-casing engages, by means of its dovetail cam 65, with the cams 66 of springs 67 and presses the latter apart when the magazine is at its downward position, and thereby permits the insertion of the cartridges into the receiver. In order to disengage the dovetail cam 65 from the cams 66, the magazine-stop is introduced, which operates in the following manner: As soon as the magazine-lever has been pulled downwardly, and thereby lowered the magazine-casing, which spreads the cartridge-stop springs apart, the magazinestop spring 63, fastened to the wall 72 of magazine 4 by means of set-screws 78, exerts its pressure against the free end 64 of the upper link of the toggle-jointed stop and presses the same outwardly, as shown in Fig. 4 of the drawings. This link is pivoted at 59,

and the lower arm of the link 65 is jointed to the upper arm of the lower toggle-link 55 by IOO IIO

means of the pin 60, which is fastened to link 55 and engages in the slot 61 of link 64. This movement will throw the lower end of link 55 and the upper end of link 65 outwardly and free of the casing, as seen in Fig. 4. At the upward return movement of the magazine-lever 5 the same encounters the projecting lower link 55, and the part 54 of the magazine-lever bears against the same and presses the magazine-casing upward, whereby in turn the projecting cam-shaped upper end of the upper link 64 is caused to bear against the outer contact edge of that part of the main frame which is designated by 62 in the drawings, which action causes the toggle- links 55 and 64 to straighten and enter their compartment, leaving thereby the magazine-casing 4 free to finish its upward motion, and thereby release the cartridge-stop springs 67 from their outwardlyspread position, by reason of the withdrawal of the dovetail cam from between the cams 66.

The bolt action, as illustrated in the drawings, contains the following features and is that of a reciprocating breech-bolt. It has a bolt-head connectedto an operating sliding bolt by means of an assembling-pin, a breechbolt lock pivotally connected to the bolt and adapted to partly rotate upon its connectingpin, a handle to operate both the breech-bolt and bolt-lock, and a firing-pin which traverses the bolt and bolt-head. The breechbolt 6 is provided with outwardly-extending guide-bars 87, (see Fig. 6,)'which are preferably formed integrally with the bolt 6. These guide-bars 87 run in guideways 85, formed in the inner sides of the walls of the receiver 2 and extend lengthwise of the receiver. The body portion of the sliding bolt has a centrally-located longitudinal bore through which passes the firing-pin 10 and its compression-spring 19. This bore begins at the forward end of the bolt and is of a diameter sufficiently large -to accommodate therein a piston 20, which latter forirs part of the firing-pin 10 and also the conpressible firing-spring 19, which latter is seated against the shoulder 29, where the large bore in the bolt 6 terminates, and the afore rentioned piston 20 of the firing-pin 10. The axis of the large bore is continued by a bore of snaller diameter for the reception of the firing-pin 10 and extends rearwardly through the entire bolt. The forward end of the bolt terminates in the two guide-bars 87, which assume the square shape, as shown in Fig. 7 of drawings, and in this shape, beginning at the forward end of the bore in the bolt, form continuations of the two guide-bars 87, heretofore referred to, and they serve for the reception of the breech-bolt head 22. The latter has square side recesses, (shown in dotted lines in Fig. 10 and in full lines in Fig. 7 and bars 87 abut against shoulders at the ends of the recesses 109, cut into the bolt-head, while the rearward end 110 of the bolt-head seats snugly against the forward outer end 111 of the sliding breech-bolt. An assembling-pin 100, as shown in Figs. 7 and 8, securely locks the bolt-head 22 to the slidebolt 6 and causes both to be moved in unison. This assembling-pin (shown in Figs. 7 and 8) enters vertically between the bolt-head 22 and the bolt 6 and has a spring-lever 101 placed at right angle to the pin, which lever is seated in a groove placed in the top of the bolt-head, and a hook-catch (shown in Fig. 10) engages with the front end of the bolthead, and thereby keeps the assembling-pin 100 securely in position.

The firing-pin 10 enters a centrally-located bore in the bolt-head, and the needle-point 21 of the firing-pin 10 penetrates the bolthead, as shown in Figs. 3 and 8.

As is usual with weapons of this kind, the bolt-head is provided with a shell-extractor 23 and ejector-spring 26, and both are movable with the sliding bolt and are actuated by ireans of the sare. The extractor 23 (see Fig. 4) consists of a centrally-located pivotlever, is positioned in a slot prepared for its reception in the upper portion of the bolthead, but placed slightly to the left of a vertical center line drawn through the bolt-head, as seen in Fig. 10 when looking toward the rear of the gun.

The object of placing the extractor 23 slightly toward one side is for the purpose of causing the extracted cartridge-shells to be thrown to this side, which will be the righthand side of the operator. The extractor is pivoted at 27 to the bolt-head, and the extractor-point 23 has a downwardly-extending catch, as seen in Fig. 4, which latter projects from the bolt-head, as shown in Fig. 4. When the sliding bolt is drawn back into this position, its upward-extending stop 89 bears against the saddle 88 of the receiver 2, thereby limiting further backward notion of the bolt, and with the extractor-head 23 slightly back of the inner side of the rear wall of the magazine-casing, giving anzple space for the extracted shell to leave the receiver, while when the bolt is thrown forward, as seen in Fig. 12 of drawings, the extractor-head 23 has entered into a notched recess 90 in the barrel and takes hold of the rim of the cartridge.

The ejector-spring 26, as shown in Fig. 9, has sinuous retracing convolutions and occupies the recess 102, cut into the under side of the bolt-head. The ejector-spring is preferably round with projecting terminals, of which terminal 24 enters a bore drilled into the forward end of the bolt-head, and terminal 25 enters into a drill-hole in the rearward end of the same. The front ter- 6 5 Fig. 8,) and the outward ends 108 of the guideminal 24 projects slightly beyond the face of the bolt-head, as seen in Fig. 9, and is flush with the projecting circumferential rim 103 on the face of the bolt. (See Figs. 10 and 4.) The rim 103 enters and seats the cartridge axially to the firing-pin and has gas-escape notches 113 cut therein. As soon as the cartridge has been placed automatically or at will against the face of the bolt-head the ejector-spring 26 is compressed and its terminal 24 sits flush with the face of the bolthead. As soon as the shell has been extracted from the barrel and lies free of the retainingwings 68 of the cartridge-stop springs 67 the ejector-spring 26 forces the shell forwardly and in connection with the extractor 23 in the well-known manner throws theempty shell upwardly and out of the receiver toward the right of the operator.

The breech-bolt has on its rear end a breech-bolt lock 7, pivoted thereto by means of pivotpin 31. This bolt-lock 7, as shown in Fig. 5, straddles a vertical centrallylo cated-web member 114, through which the firing-pin 1.0 passes, and is further provided on either side of the central web 114 with semioircular lugs 115, (see Fig. 3,) and when the bolt-lock 7 is in the closed position the outer end of a segmentally-shaped stop 30, which forms part of the sliding bolt, will bear against the shoulder 116 of the semicircular lugs 115 and prevent further downward movement. The upward movement of the bolt-lock 7 is limitedby reason of the rear end 117, Fig. 4, bearing against the inclined shoulder 118 of the rearmost end of the sliding bolt. Vhenever the bolt-lock 7 is in the position as seen in Fig. 3 and Fig. 5, the breech-block cannot be drawn backwardly until the bolt-lock is thrown upwardly into the position as seen in Fig. 4, whereby the semicircular-shaped ed ge 119 of the lock, Fig.

3, which in the locked position engages the edge of the semicircular stop 30, has rotated over the same, whereupon the sliding bolt is free to move backwardly.

The top of the rear end of the bolt-lock 7 is provided with a transverse notch 32, into which will seat itself the locking member 17 of the firing-pin 10, as seen in Fig. 4, the firing-pin 10 being drawn forwardly by means of its s ring 19. This arrangement will effective v prevent a discharge of the weapon in any other but the proper iiring position of the same.

In order to open or close the boltelock 7, a handle 8 is provided, which rotates upon a pin 34, which latter is stationary on and movable with the bolt-lock and is positioned eccentrically to the main bolt-lock pivot-pin 31 upon the outer lever-arm 120, Figs. 1 and 2, which lever is integral with the bolt-lock and is located on the right side of the gun. This lever-arm 120 has a partial annular cutout, (shown in Fig. 2,) which forms thereby two inner end shoulders 91 and 92, designed to receive the impact of an actuating and thereon-impinging cam-lug 33,- which latter forms a part of the handle 8 and moves therewith. This handle 8 is held in position upon the pin 34 by means of a holding spring-key 96, which latter enters into the drill-hole 97, located in the pin 34. The spring-key 96 has an outer extending shank 94, made of tempered steel, and is located in a slot 35, cut into the under side of the handle S. The slot 35 conforms in shape to the sh ape of the partly-bent shank 94 of the key, and the latter bears against the entire inner side of the slot 35, which is concave in form. The under concave side of the shank 94 has a centrally-situated catch which engages with and bears upon a transverse pin 95 in the handle and which passes through the slot 35 and the adjoining walls of the handle. The tendency of this spring holding-key 96 and the object of the same are to hold the handle and the th ereby-actuated mechanism in a forwardly-directed strained position. In case now the handle is thrown upwardly the handle-lugs 33 will partly revolve and engage with the rear cam-lug 91 of the leverarm 120, as shown in Fig. 2 in dotted lines, and cause the bolt-lock to be lifted and released from the segmental stop 30, whereupon the breech-bolt 6 is free to be moved backwardly into the position shown in Fig. 4 of the drawings by means of a continued drawing motion of the hand and arm of the operator. However, prior to the time that the handleelug 33 reaches and engages with the rear shoulder 91 the lug 33 impinges against the cam 93, which latter is stationary with the iring-pin head 16, to which is at tached the firing-pin 10 by means of pin 1S and to the lower end of which is attached also the notched bar 11, with notches or shoulders 14 and 15, and the outward rear side of which terminates in a loop or eye 9. The notched bar 11 slides in a groove S6, located in the under side of the bolt 6, and the notches or shoulders 1 4 and 15 are provided to engage with the sear 12, pivoted at 39.

The trigger and sear mechanism, as shown in Figs. 1 and 4 of drawings, is simple in construction and consists of a plain trigger 13, pivoted at 40. The inwardly-extending arm of the trigger-lever has a square-formed engaging lever-arm 41, which in the position of the gun as illustrated in Fig. 3 does not come in contact with any part of the sear 12, but which when in the locked position (shown in Fig. 4) bears against a projecting leverarm 121 of the sear 12, which latter is brought to assume this position by means of the searspringI 37, bearing upon a second lever-arm 122 which causes the sear lever-arm 121 to bear against lever 41 of the trigger and at the same timecauses a third sear lever-arm 36 to rise above the level of the bottom face of the notched bar 11, which is fastened to the fir- IOO IXO

ing-pin head 16. This arrangement will cause the firing-pin head 16 at its return forward motion to be arrested by coming in contact with the foremost notch or shoulder 14 of the b 11 and keep same in this position until the bolt-lock 7 has been locked, and thereby cocks the weapon. The second notch or shoulder 15 is designed for the usual pur ose of setting the gun at half-cock. By pul ing the trigger 13, which is, as usual, protected by the trigger-guard 90, the sear leverarm 36 becomes released from the notch or shoulder 14 and the firing-pin is in position to explode the cartridge, and the bar 11 passes over the sear without permitting the outer point of sear lever-arm 36 to engage the notches or shoulders and brings the sear 12 nd trigger 13 back to the position as seen in The operation of my improved firearm is as follows: The o erator grasps the handle S and pulling bac wardly the handle partly rotates upwardly, and the cam 33 impinges against cam 17, which causes the ring-pin head to be withdrawn. (See Fig. 2.) The handle continues to rotate upwardly, which lifts the bolt-lock 7 and unlocks the sliding bolt 6 from the segmental stop 30. The firing-pin head is forced forwardly again by action. of the firing-pin spring 19, whereby the rounded shoulder 17 becomes engaged with the cut-out 82 on end of the bolt-lock and holds the same in the unlocking position. This operation unlocks the breech-block from the receiver, which permits the operator to pull backwardly the sliding breech-bolt 6 to the position as shown in Fig. 4, in which operation the lever-arm 12() moves downwardly into a longitudinal recess 123, formed in the front upper portion of the stock and the adjacent part of the receiver or lock casing and moves backwardly in said recess. The empty cartridge-shell is automatically being ejected now and replaced by a new shell, and the lever-arm 36 of the sear 12 catches in the notch or shoulder 14 on the return forward movement of the breech-bolt. The gun is now cocked and ready to be fired by pulling the trigger. When desired, the gun can easily be set on half or safety catch by holding back in the ring-eye 9 of the firing-pin head while the trigger is being pulled. In order to load the magazine, pull the breech-bolt to its rearmost position, as described above, then push down the magazine-lever by pressing on the thumb-piece 50 of the ma azine-lever lock 52. This swings the magazine-lever 5 downwardly, which forces the empty cartridge-carrier 73 down and locks same in the magazine by means of pin 77 being held in the horizontal slot 81 of the magazine. The magazinestop springs 67 hold the retaining-wings 68 open and allow of the rapid insertion of new cartridges into the magazine. When filled,

push upwardly the magazine-lever, which will release the cartridge-stop springs and prevent the cartridges from being forced out of the receiver. The magazine-lever catch 52 is now locked again and the cartridge-carrier and the retaining stop-springs are released, and the uppermost cartridge takes its position in the receiver and in line with the bolthead. Then ush the sliding bolt forward by means of t e handle and the same will be locked by means of the automatic action of the bolt-lock, and the gun is ready to be fired again.

If it is desired, the magazine can also be loaded from the top of the receiver by pushing the head of the cartridge backward under the cartridge-stop s rings. It is apparent that the gun can a so'be used as a single-Y loader by inserting the cartridges one by one successively after each firing.

In this application I have shown and described a complete magazine-gun involving both the magazine mechanism and the breech mechanism; but in this application only the breech mechanism is claimed, the magazine mechanism being made the subject of a divisional application filed by me August 10, 1906, Serial No. 329,978.
