` To aZZ whom it may concern:

Be it known that I, JOSEF ScHULHoE, of thel ing countries, to wit: in Great Britain July 12, 1886, No. 9,066; in Austria-Hungary July 13, 1886, No. 4,336/33,443; in France October 5, 1886, No. 478,875; in Belgium October 30, 1886, No. 74,923, in Italy November 12, 1886, No.' 8,414; in Spain February 16, 1887, No. 10,452, and in Germany May 5, 1887, No. 38,884,) of which I declare the following to be a specification.

This invention relates to improvements in magazine-guns, and has special reference to that class ofre-arms in which a sliding breech*- piece or bolt is employed, and wherein the magazine is arranged between the two parts of the stock in immediate connection with the cartridge-chamber in the breech-receiver.

The magazine, which has the form of a drum, is attached to the stock and breech receiver or case underneath the latter, which is in this case provided with a corresponding opening in the bottom to permit the raising of the cartridges from the magazine into the breech receiver or case. This magazine-drum is made to contain from eight to fourteen cartridges, and is, parallel with its axis, provided with an interior central arbor or small drum, around and parallel to which the cartridges are arranged. This interior arbor turns in borings, and is rotated in one direction by the unwinding of a small chain arranged at the one end, the other end of which said chain is attached to the lid of the magazine. Thus when said lid is opened the central arbor of .the magazine receives one turn in one direction, when, as the door or lid is fully opened, said arbor is stopped by a spring-pawl catching into a corresponding notch in its end. The other end of this arbor is provided with a spiral spring, which is tightened or wound when the magazine door or lid is opened and the arbor rotated in one direction. By the action of thebeforementioned pawl preventing the turning back of the arbor the spiral spring is also kept wound until the magazine-door is closed, when a pin, attached to the latter, strikes the pawl, thereby releasing the arbor, which is now turned back into its original position. This turning back causes the feeding of the cartridges into the chamber in the breech case or receiver in the following manner: On its surface, parallel to its axis, the arbor carries aslightly-oscillating lever, which, when the magazine-door is open, stands in its highest position to the right against the lower side of the case. The cartridges having been thrown into the magazine and the door closed, the spiral spring, acting upon the arbor, forces it to turn, whereby said oscillating lever presses laterally against the last cartridge, pushing them all before it, so that one cartridge after the other is passed up an incline, with which the magazine is provided, into the breech-receiver case,where they are struck by the sliding breech piece or bolt, pushed home into the cartridgechamber, and subsequently iired.

When the gun is to be used as a single loader while the magazine is filled, a slide is pushed into the magazine, which passes over the cartridges and prevents them from passing out.

Fig. 3 is a rear view ofthe magazine with the stock removed and the magazine-flap opened. Fig. 4 is a rear view of the magazine with closed flap. Fig. 5 is a horizontal section of the magazine. Fig. 6 is a top view of the same. Fig. 7 isa front view of the closed magazine. Fig. 6l is a view ofthe cartridge-transport lever. Fig. 8 is a vertical section of the closed -magazine.

Like letters denote like parts in all the iignres.

The magazine of my improved gun is, as aforementioned, arranged between the two halves of the shaft, and consists of a drum or casing, g, preferably1 of thin sheet metal,which is attached to the forward and rear halves of the shaft by means of the lugs p2, Figs. 2, 4, and 5, and p', Figs. 6 and 7, and appropriate screws. A stud or projection, gs, of the magazine fits into a suitable recess ofthe breech-receiver d, so as to fix thev magazine to the said breechreceiver. The upper part of the drum gis cut away in order to allow a cartridge to pass through the same, the drum being provided with an incline, g5, to enable the ready entrance of the cartridgeinto the breech-receiver, Fig.8. The inner walls of the drum are provided with spiral surfaces m m, the object of which will be fully described later on in this specification. A second drum or shaft, h, is arranged within and concentric to the walls of the'drum' g, and has its bearings in the end walls of the same. The shaft h is at its rear end provided with a journal, h2, Figs. 3 and 4, to which the chain h5 is attached. The other end of this chain h5 is attached to the flap g* of the magazine, as shown in Figs. 3 and 4. The forward end of the shaft or axis h is provided with ajournal, i, around which an appropriate spring, i2, is coiled. This spring '2 is attached to the journal i of the shaft 7L by pins or screws i5 i6, and to the front end of the drum lf/,by means of the pin, peg,or screw t3,in such manner that when the shaft h is rotated the spring will be put under tension. This movement of the shaft h is caused by the opening of the iiap y, as follows: The chain h5, which connects the flap g4 of the drum g with the shaft h, runs over a guide pin or roller, h, Figs. 3 and 4, and is coiled on the journal of the shaft when the drum is closed. This end of the shaft h is provided with an eccentric-disk or offset-wheel, it, in which a pawl, h3, gears when the ap g4 is opened, which said pawl is held in gear with the said disk by means of the spring h4 when the flap is opened. When the iiap is closed, the disk or wheel takes up the position shown in Fig. 4, so that when the flap is opened the chain h5 will cause the shaft h to make almost one revolution before the pawl comes in gear with the tooth or offset of the disk or wheel, so that the shaft h is held in the position shown in Fig. 3 until the flap g4 is again closed. In closing the said iiap g*- the pin g5 comes in contact with the lever-pawl h3, so that the same is brought out of gear with the offset or tooth of the disk or wheel '54, the chain lays itself loosely against the wheel until the disk or wheel is freed, and is wound on the shaft by the force of the spring 2, which was put under tension when the shaft h was rotated in opening the flap g4. The so -called cartridge-transporter7 on the shaft h, Figs. 5, 6, Gf", and- 8, consists of an oscillating lever, q, on the pivot or screw q2 g3, the movement of which is limited by the length of a slot, i, in which a stud, qe, moves. A spring, q', arranged laterally on the transport-lever q, bears against the shaft h and retains the lever parallel to the said shaft.

The operation of the magazine is as follows: In order to fill the magazine the flap g4 is opened and puts the spring 112 under tension,

as aforementioned. The pawl h3 falls at i* onto d and the transport-lever stands in the position shown in Fig. 8, near the opening. The cartridges are now loosely inserted in the magazine and roll around the shaft l1., when the weapon is held to the one side unt-il the first cartridge comes in contact with the incline g5 at the opening or cavity in the breech-receiver, Fig. 8. The magazine is now filled and the door g4 closed, the pin g5 releasing the pawl h3 and giving the shaft h free motion. The spring i, having been put under tension by the rotary movement of the shaft 7L, has the tendency to return to its original position. The transportlever q presses against the last cartridge, so that the cartridges are pressed forward until the foremost cartridge ispressed up onto the incline g5, and when the sliding breech-piece is drawn back through the opening in the breech-receiver into the cartridge-chamber in the same. In closing the breech the sliding breech-piece a comes againstthe flange of the cartridge and pushes the said cartridge up the incline o, Figs. 5 and 7, into the cartridge-chamber in the barrel. When the last cartridge has reached the incline g5, the transport-lever q is in the position shown by the dotted lines in Fig. 8, and the spring if is released from tension.

It will be evident that .the operation of the parts will remain the same whether one or more cartridges are laid in the magazine. If one cartridge islaid in the magazine,the shaft h, and consequently the transport-lever g,will be moved in proportion, so that this cartridge is also brought under the opening or cavity in the breech-receiver.v Vhen the magazine is full, the closed breech-piece will prevent a cartridge from rising through said opening or cavity in the breech-receiver, whereas each time the breech-piece is drawn back a cartridge will rise sufficiently, so as to be able to force the same into the cartridge-chamber in the barrel. The Hap g4, which is hinged atg to the magazine, is held in closed position by means of a suitable spring-catch. When the sliding breech-piece is drawn back, the flange of the cartridge-shell will strike against apin, r, fixed to the drum g, and extending through a cavity, r', in the breechreceiver d, so that the same is ejected.

In order to be able to employ my improved weapon as single loader with filled magazine, I employa slide, j, which, when not in use, occupies the position represented in Figs. 3, 4, 7, and 8. If the said slide j is pushed forward by means of the knob j', the same will occupy the position, as shown by the dotted lines in Fig. 6, over the cavity or opening of the breech-receiver, and consequently over the opening in the drum and above the cartridges in the same, thus preventing the said cartridges from leaving the magazine. The sliding breech-piece will now glide freely over the ICO IIO

cartridges in the magazine, so that the weapon can be used as single loader until the slide 7' is withdrawn.when the magazine again cornes into action. As the magazine is not located immediately beneath theopening or cavity in the breech-receiver, but a trifie to the rear of the same, the inner walls of the drum g are pro vided with spiral guides,so that the cartridges, which originally lay somewhat to the rear of the said opening or cavity in the breech-receiver, will on their way upward be gradually pushed forward until the uppermost cai`- tridge cornes in line with the said opening. A rib, n, applied to the inner wall of the magazine, serves to hold the cartridge in horizontal position.

rIhe magazine can be readily emptied by simply opening the flap g4 and allowing the cartridges 4to roll out. If desired, the walls of the magazine can be perforated at g2 in order to be able to ascertain whether the magazine is filled or not without having to open the ilap.

Having now particularly described and ascertained the nature of my said invention, and in what manner the same-is to be performed, I declare that what I claim is- 1. In a magazine fire-arm, the combination,

I with the stock, barrel, and sliding breechpiece, of a magazine located beneath the breechreceiver, and consisting of a drum or casing, g, having a cartridge-receiving opening therein and a hinged flap closing Said opening, a rotary shaft, 7a, arranged concentrically within said drum g and havingjournal-bearing within the end walls thereof, a chain, h5, connected at its ends,respectively,to the rear of the shaft 7L and to the flap g4, and a spring, il, connecting, respectively, the front end of said shaft li and the front end of the magazine gun, substantially as and for the purpose set forth.
