To all 1117mm it nmg concern.-

Be it known that I, .Licon SMITH J ARMANN, a subject of the King of Norway, residing at Ghristiania, Norway, have invented new and useful Improvements in Breech-Loading Fire- Arms and in Repeating Magazines Therefor, of which the following is a specification.

Fire-arms constructed according to this invention have a breech part which consists of the breech-case and of the following six parts, which are movable thereinviz., the breech bolt, the closing and thrust block, the hammer, the extractor, the striker, and the mainspring. This mechanism is applied to a gun which is provided with a cartridge-magazine in the upper part of the gun and a cartridge magazine under-the barrel, the whole arrangement being such that the gun may be supplied first from one magazine and then from the other magazine 5 or the gun may be made with the upper magazine alone or with the lower magazine alone. The breech mechanism remains substantially the same in all the afore said eases.

The breech-case A, Figs. 1 and 2, whiclris screwed to the barrel, consists of a cylindrical tube, as usual in the bolt system, inside of which the movable breech mechanism works during the manipulation of the gun. The breech-case, as described below, and also the details of the breech mechanism and its arrangements, differ essentially from older types in Belgium January 15,1833, No. ',ItiI,'and in Germany of this system. Thus the thrust or recoil is taken up by a slot, (6 which receives the lever of the closing-block 0, Figs. 7 and 8, and by a groove, a, which receives the thrust-knob of the closing-block, so that the thrust or recoil is taken up diametrically on both sides of the breech-case, which, as regards solidity and accuracy in firing, has considerable advantages. For the downward movement of the lever of the closing-block, a curved inclined plane, a a, in the aforesaid slot a causes the cartridge to be pressed into the cartridgechamber, and in the reverse movement of the lever a curved inclined plane, a a in the aforesaid groove a causes an effective extraction of the cartridge-case. Thereby the thrust 7 knob C of the closing-block 0, Figs. 7 and 8,

is forced over this curve. A slot, a, receives the knob d of the hammer D, Figs. 9 and 10, that has the full and half cock notches d and d and the third knob, 0 of the closing-block O, and it'serves, also, for guiding the movable breech mechanism in its forward and backward motion during the manipulation of the gun. A notch, a, at the rear serves as a support for the projection h, Figs. and 16, for the trigger-spring. A mortise, a receives the cocking-knoblrof the trigger-spring. A lower lug, a", Figs. 1, 32, and 33, serves for fastening the breech mechanism to the stock, and by its lateral projections to on the said lug the spring of the cartridge-feeder for the magazine under the barrel is secured, as will be described later on with reference to the magazine under the barrel. There is also a knob, a, at the rear for fastening the mechanism to the stock. The upper stop-notches, a a, stop the movable breech mechanism from moving backward farther than till the extractor-head abuts against these notches. A recess, a, in the socket for the barrel receives the extractorhook 0, Figs. 11 and 12, when the mechanism is closed.

The special arrangements of the breechcase where the magazine K is to be made detachable are as follows: On the right side of the breech case there is a recess, a, into which is inserted the stud of the loose magazine. Near the top and more to the rear there is a recess, (0,f0r mounting the magazine. A screw-hole, a, is provided on the bottom of the breech-case for an ejecting-pin, which is only necessary when the loose magazine is intended to be used.

The movable breech mechanism consists of the following parts: The breech-bolt B, Figs. 14:, 15, 50, and 62, is a cylinder with a front end, I), having a hole for the striker F. In the interior of this cylinder the mainspring and the striker are generally placed, the latter being in this case guided in a lateral groove, 1)". The bolt has alug, b, at the rear, by which the closingblock draws the bolt back. On

1 top a circular cut, 1), opens laterally and secures the end eof extractor E, Fig. 11. A

recess, Z1 receives the knob e on the front end of the extractor. The bolt B has a fiat face, N, to permit it to pass over the ejectingknob a, in the bottom of the breech-case.

The closing and thrust block 0, Figs. 7 and 8, is formed with a pivot, c, that fits in the hollow cylinder 1) of the bolt, and there is a hole, 0, for the striker F, Figs. 13 and 14.. On this pivot the closing-block 0 turns sufficiently for opening or closing the mechanism. The closing-block is provided with the lever-knob 0 by which the mechanism is worked during the manipulation of the gun, and when the mechanism is closed this lever takes up the thrust in the aforesaid slot (6 of the breeclr case simultaneously with a lower thrust-knob, c, that takes up the thrust in the aforesaid groove a in the breech-case. Further, the closing-block is provided with a projection, 0 that engages with the rearlug or stud, b of the bolt B, Fig. 1a. YVhen the lever is turned up, therefore, in drawing the mechanism backward, the bolt is carried along by a spirallyformed incline plane, 0". at the back. The gun, as usual in the bolt system, is cocked when the closing -block is thrown up. A curved covering-plate, c. on the closing-block protects the mechanism against dirt and imparts by its forward edge and rounded corner 0 a forward impulse to the sliding carrier in the magazine. This curved plate also looks this magazine when the mechanism is closed and keepsit firm during firing.

The hammer D, Figs. 9 and 10', has a spirally-formed inclined plane, d, corresponding with the inclined plane c of the closing-block, as shown by dotted lines. Through the middle of the hammer is a hole, d, partly screwthreaded, for connecting the striker F to said hammer. The hammer is provided underneath with a knob, d", with a nose, (1, for fullcock and a notch, (1*, for half-cock. This knob is guided in the slot a in the rear end of the breech-case A, Figs. 1, 2, and 33. There is also a front projection, (P, which also serves for guiding the hammer in the breech-case. By the comb d the gun may be full or also half cocked. The point of the spirallyformed inclined plane a in the closing-block C, Fig. 7, rests in a recess, d formed in front end of cock, and this prevents the hammer from turningwhen the mechanism is opened.

The extractor E, Figs. 11 and 12, consists of a very powerful spring, 0, provided. with a round button-formed knob, e, by which it is fastened to the thrust-bolt B at b, and when in this position the extractor is turned till ,7

a knob, 0 at the front enters the recess b at front end of the bolt B, when the extractor is secured and in its right position. To take out the extractor only requires the lifting of the knob e out of the out If in the bolt and the turning of the extractor a quarter-circle to either side. The fore part of the extractor E isprovided with a head, 6', each projecting side of which, when the breech mechanism is open, abuts against the stop-notches a a in the breech-case, and thus arrests the backward movement of the mechanism. a" is the ex ti'actingclaw. The extractor-head c is also, at the right side, provided with a lug, 0", Fig. 12, that gives motion to the repeating mechanism of theloose magazine K, Fig. 19. Bylifting up the extracting-claw (2 (usin for instance, the right forefinger for that purpose) sufficient to allow the two side projections of the extractor-head c to slide over the strengthened part of the breecltcase, (at the aforesaid thrust-slot (62,) the movable breech mechanism may be removed from the breech. By pushing the mechanism forward it may be again refitted, the extractorspring thereby beinglifted up and sliding freely up the inclined plane on the rear of the breech-case until the extractor-head c has passed the above-named strengthened part of the breech-case, whereupon the extractor-head 6" again drops down into the stop-notches a a", and the mechanism is then in the position shown in Fig. 50. This extractor has thus the following functions to perform, viz.:

First. To extract the cartridge-case from the chamber as usual--viz., by the hook 0*.

Second. To eject the empty case. This is done only through the tension of the (3X- tractor-spring, which presses the rim or flange of the cartridgecase so hard against the bot tom of the breech-case that the friction thereby produced is sufficient to throw the empty case gently clear of the gun.

Third. To stop the travel of the movable mechanism.

Fourth. To assistin removing the movable breech mechanism from the case.

Fifth. To secure the movable breech mechanisin.

Sixth. To guide the back and forward movements of the bolt.

Seventh. iVhen using the loose magazine K it serves also for giving partial impulse to the repeating mechanism of this magazine.

The striker F has at the front end a head, f, that fits in theinner cylinder, 7), of the bolt B. In instances where a cartridge bursts, the head has to let the gas escape, and for this purpose the head is formed with grooves 0r hollows, f, by which the violent repulse of the piston is partially prevented. Near the middle the striker has a shoulder, f which in such cases is forced into contact with the pivot c of the closing-block, Fig. 8, and thereby prevents any flow of gas toward the eye of the operator and keeps the mainspring from being over-forced. To prevent the striker from unscrewing itselfthe headf" provided with a feather, f, that moves in the cone spending groove, Zr, in the bolt. The back end of the striker has screw-threads f, which are for screwing it into the hammer. The main spring 0 is, as usual in this system, a helical steel spring.

The trigger mechanism consists of- First. The tri gger'sprln g H, Figs. 15 and 16, which is placed beneath the breech-case,at the rear of the same, between the notches of and a provided therein, and has a hook, it, that catches in the back notch, (17, in the breechcase A, whereby the spring H, fastened by a screw, is protected against the shock caused by the forward movement of the breech mechanism. The spring has a slot, 71 for the trigger J, which is hinged thereto by a pin, 71?. On the upper side, at the foremost end, this spring has the cocking stop-lug it, that enters the opening a in the breech-case, where itiirst meets with the full-cocking notch d of the hammer D.

Second. The trigger J, Figs. 17 and 18, has a rounded projection on the top a, which abuts against the breech-case, and by which most of the pulling is done. \Vhen this first touch is felt the rest of the pulling requires a con tinual and but very slight pressure on the trigger.

The following is a description of the next part of my invention, which refers to the re peating detachable magazine K, Figs. 19 and 56 to 60. This is mounted on the top of the gun, standing out at an angle and communieating directly with the breech. Though preferably detachable, it may, if desired, be permanently fixed. 7

The magazine K consists ofa lower case, 7;, for the mechanism. To this case is soldered the cartridge-holder 7.", inside of which is a zigzag spring, 73, that presses the cartridges down in the loadingopening in the breechcase, the cartridge which is retained in the magazine, Fig. 56, by the cartridge-flange, dropping into the notches 7t one 011 each side. The magazine has an inner leatherlining, it, in front, to prevent the points of the bullets from being damaged by the recoil during the firing with the magazine loaded. The lower case, 7:, has a cylindrically-bored rear part, 7:, in which slides carrier L, Figs. 2i and 25. The case has on one outer and lower side an eye, 7;, Fi 20, in which is inserted a stophook, N, Figs. 30 and 31; also a lower stud, k Fig. 20, that enters the eye a. in a corresponding recess on the right side of the breechcase, and by which the magazine is mounted. There are two projections, If, one on each side, inside the magazine-case. These support the flange of the cartridge when the carrier is pressing the extractor over the cartridge flange A. The tongue 7.1 at the rear extends a little under the curved plate 0 of the closingblock 0, and by this the magazine is kept quite lirin when the mechanism is closed and ready for firing. It is here also formed with a slot, 76", for the stop-pin Z of the carrier, Fig. 2i, and with a slot, If, for guiding the carrier L at the left side. In frontit is provided with a projection, 7.1, Fig. 23, that enters a slot, Z", in the front en (1 of the carrier guiding-arm 7 Fig. 2st. At the bottom, in front, there isafiange, 7: for the point of the bullet to rest on, and

twoinnerinclincd )lanes. 7;. oneon eachside for guiding the cartridge, as shown at Figs. 23, 56, and 57. A magazine of such a size that it can hold seven cartridges appears to be the one most suitable. Having one cartridge in the barrel,eight shots will then be available. The carrier L, that moves inside the cylindrical part k in the magazine, is formed like a cylindrical plug, Z, provided with the extractor Z, by means of w rich the cartridge is carried along so far that its. flange may pass out through the opening k, and the bulletpoint gets clear of the aforesaid bottom flangeseat, It. The cartridge is then free, and is pressed down in the loading-opening ol' the breech-case by the zigzag springlr, Fig. 19, the fiat arm Z serving as a guide for the carrier, for which reason it has the aforesaid slot Z for the lug It. There is a hole, Z bored aslant through the cylindrical body of the carrier, and in this turns a cartridgeguard, M, Figs. 27, 2S, and 29, by the aid of which the mechanism of the magazine may be put into motion or stopped at pleasure, so that the gun in that case could work as a single-loader or with a bottom magazine. The carrier L receives its motion in one direction through the said guard M, when this is placed in such a position that the extractionstud 6 Fig. 12, by the backward movements of the mechanism, can get hold of the catch-knob m on the magazineguard, and in the other direction the carrier receives its motion from the roundedeff corner a of the closing-block which incloses the mechanism, presses against the end Z of the carrier, and moves it forward.

The cartridge-guard M, Fig. 27, of the magazine K consists of a small central pin, m, provided with an outer ielieal spring, m, and turning in the aforesaid oblique hole Z in the carrier by means of a catch-knob, m. The pin, when turned half round one way, comes right opposite. the lateral front lug, c, Fig. 12,-of the extractor, and in opening the mechanism this lug will draw the carrier back, and thus let the cartridge in the magazine held by the carriers extractor Z, Figs. 25, 56, and 57, drop down in the loading opening of the breech-case. In the reversemovement of the pin the catch-knob on will come so low that the extractors lug c" Fig. 12, will pass over it, and no motion will then be communicated to the magazine, and firing with the gun as a single-loader may go on without interfering with the magazine at all. The helical spring m, together with a small stud, m, on an arm, on, for turning the pin, serves as a stopper for the two positions in which the magazine is put into motion or stopped.

The stop-hook N, Fig. 13, fixed in the eye k on the magazine K, consists of a hook part, it a on a pin provided with a helical spring, a, which draws the hook part a into a notch, (6, Fig. 1, in the breech-case by which the loose magazine is secured.

Fig. 56 shows the position of the cartridge in the lower part of. the magazine K at the moment when the extractor Z, fixed to the corner pressed forward by the covering-plate c, has seized the cartridgeflange.

Fig. 57 shows the position of the carrier L, with cartridge drawn back by the extractorstud 6 the cartridge here being free to pass down into the loading-opening of the breechcase.

Figs. 58 and 59 show the gun with the magazine mounted and the mechanism closed ready for firing.

Then the gun is also to be provided with or adapted for the magazine under the barrel, I make such magazine in the usual tube form, as I shall now explain with reference to Figs. 32 to 55. This tube S is made to take eight 'cartridges,and is at one end secured in a socket, a, or the breech-case A,(shown separately in Fig. 32,) and at the other end to a stud on the barrel. This tube-magazine also contains the usual helical spring and runner, that press the cartridges one after the other into the breech.

The breech-case A, Figs. 32 and 50, as adapt ed for the magazine S, is arranged as follows: A slot, a, is formedin the bottom,and in this slot works the cartridge-feeder 0, Figs. 88, 39, and 40, which is guided by a rib, 0 fitting in the inclined recess a in one side of the slot a, and is hinged to the breech-case at 0. A

screw-hole, a, on the side of the breech-case receives the stopper Q, Figs. 44, 45, for the magazine S, and there is a front recess and a rear recess, a, for fixing the end of that stopper in its two positions. (6 is a stop that limits the movements of the stopper. The eartridge-feeder 0 receives the cartridge from the magazine S and receives its impulse through a spring, 1?, Figs. 41 and 42, and the inclined plane leading to the hollow I) in the under side of the bolt B, Fig. 4, in the following manner: hen the bolt Bis drawn so far back that the lifting back end, 0 of the cartridge-feeder enters the said recess, the spring P acts 011 the stud 0 on the cartridgefeeder and brings the front part of the same low enough to receive the cartridge from the magazine. It is brought back to its former p0 sition by means of the inclined plane at the recess 5 as this plane in the forward movement of the mechanism presses the back end 0 of the feeder down and consequently the cartridge is lifted up, as shown at Fig. 53. The cartridge that the scoop has received from the magazine-tube,being forced up,is stopped against the back part of the opening a a in the breech-case. By having the aforesaid recess b Fig. 4, in the under side of the bolt so placed, and by having a longitudinal rib, 0, of the cartridge-feeder resting in the outer longitudinal groove, b", in the side of the bolt, the cartridge-feeder, which in this case forms the bottom of the breech-case, is prevented from falling down before the empty case is ejected by the extractor E. The rib 0", as long as it is in contact with the outer groove,b, in the bolt, also relieves the lifting end of the feeder 0 from the reacting pressure caused by the extractor when in the act of ejecting the empty cartridge-case. NVhen the cartridgefeeder is down, Fig. 50, the rib 0 and the inclined recess a a, Fig. 34, in the bottom of IIO the breech-ease form a passage in which the cartridge-flange is guided, and whereby the cartridge is prevented from getting out of the feeder before it reaches the extremity of the opening in the breech-case at the rear of the feeder, where the cartridge-flange at one side gets clear of the rib 0, and at the same time it is released at the other side by a notch, a, in the side of the breech opening, and is then at liberty to be lifted up in the breech-case by the cartridge-feeder O. The lug 0 on the front end ofthe latter stops the cartridge in the magazinetube, the same being liberated by the guard t the moment the mechanism is closed, and it lies now ready to enter the cartridge-feeder when the mechanism is again opened. The pin 0 through the lug o of the feeder serves for giving impulse to the cartridge-guard R while closing and opening the mechanism, as the pin then alternately comes in contact with the arms of the cartridgeguard above and below its fulcrum. There is a rib, 0", across the fore end of the scoop-formed part of the cartridge feeder, that lifts the cartridge, and thereby facilitates its entrance into the cartridge-chamber. A projection,o,prevents the cartridge flange from falling down behind the upper end of the cartridgefeeder when this is down. The cartridge-feeder spring P is formed with a front stop in the rear. It has also a notch, 9 by which it is fastened to the screwed lug a" under the breeclrcase A. The back arms of the spring have hooks 11 by which it is held fast when acting on the transverse pin 0 of the arm of the feeder. Thus this spring presses the cartridge'feeder down when free of the stopper Q of the repeating mechanism.

Through the pin 0 in the back end, 0, of the feeder this spring also depresses hook, r, of the cartridge-guard R.

The stopper Q, Figs. 43 and 44:, of the repeating mechanism consists of a handle having at one end a screw, q, that fits into a hole, (6, Figs. 33 and 34., on the left side of. the breech-case. The end of the screw q has a short stud, q, that has one-half of its diameter filed off to a D-section, that permits it, when placed in one position, to pass through the slot 0 in the scoop of the cartridge-feeder, and when placed in the opposite position enters that part of the hole 0 in the scoop of the cartridge-feeder not filed out, and thus keeps the feeder up and fixed, and the gun may then be worked just as if it had no magazine S.

To keep the stopper steady in its two positions,the handle or arm q is formed as a spring, provided at the extremity with a small projection, that enters into a recess, a, in the outer side of the breech-case.

The cartridge-guard B, Fig. 46, consists of a balance-lever, the two arms or ends 1' and r of which form an angle, and it turns on its center-pin 0- that works in the hole a in the magazine-tube socket a, Figs. 82, 33. The guard has a tooth, 1", that enters into a slot opening, a in the tubesocket, and hinders the cartridge that comes from the magazine fore end, 0', of the feeder.

from getting farther than to this claw, which is pressed into the eye in the tube-socket a by the impulse that the feeder-spring gives to the feeder and its stud 0 at itslowcr front end. As this latter abuts against the lower arm, r, of the guard and forces this down, and thereby also the tooth into the tube-socket a this of course prevents the next cartridge from following the one that has passed into the feeder. The pressure of the helical magazine-spring upon the cartridge, which is stopped against the claw of the guard, keeps't-he claw in the sock et,'as this pressure takes effect above the center about which the guard turns. The other impulse that the guard receives is also communicated to it through the pin 0 at the rear end of the feeder, as this pin, when the cartridgefeeder is lifted, pushes the upper arm, r, of the guard forward, and thus draws the guard-s claw r out of the tube-socket a, and the cartridge resting against the claw is made free and abuts against the lug on the An end projection, u, Figs. 50, 52, and 53, on the barrel extends into the loading-opening of the breech-case, whereby the bullet-points, at the rapid forward movements of the mechanism, are pre vented from being thrown up so high by the 9 cartridge-feeder as to abut against the edges of either the barrel or breech-case in the loading-opening, and thus hinder the cartridges from getting into their places.

The mechanism proper of the gun is so 0011- structed that itmay also be used either for a repeating-gun with upper magazine, or for a repeating-gun with lower magazine, without removing or changing any of the parts of which the mechanism consists.
