SPECIFICATION forming part of Letters Patent No. 298,494, dated May 13, 1884.-.

Application tiled December 7, 1883. (No model.) Patented in England May 11. 1833, No. 2,401; in France November 10, 1882i, No. 158,473; in Belgium November 14, 1883, No. 63,211, and in Italy December 3l, 1883, No. 16,161).

To all whom, it may concern:

Be it known that 1, THoRsrrnN NORDENFELT, a subject of the King of Sweden, residing at 53 Parliament Street, in the city of Westminster, England, have invented certain new and useful Improvements in Cartridge Holders or Magazines for Use with Breech-Loading Fire-Arms, (for which I have received Letters Patent in Great Britain, No. 2,401, dated May 11, 1883; in France, No. 158,473, dated November 10, 1883; in Belgium, No. 63,211, dated November 14, 1883, and in Italy, No. 16,169, dated December 31, 1883,) of which the following is a specification. i

4This invention has for its object improvements in cartridge holders or magazines for use with breech-loading fire-arms. For this purpose I form a lcartridge-holder case or magazine of two side plates held at such a distance apart that a row of cartridges may be placed between them with the heads of all the cartridges lying in the same direction, and The plates keep the cartridges in a line, but yet permit the cartridges to move freely between them. The ends of the holder are closed in to prevent the cartridges moving endwise. At that end of the case which receives the base end of the cartridges two grooves or rabbets are formed,

onein the back and the other in the front plate for the flanges at the base end of the cartridges to lie in. The cartridges are inserted into the holder at the top, which` is left open to admit of cartridges being placed into it.

The upper parts of the back and front plates of the holder are made to spring somewhat together, so that when cartridges have been placed into the holder they cannot be jerked out from it. At the bottom of the holder isa slide upon which the lowest cartridge in the holder rests, and by which the cartridge is engaged, the end of this slide being formed with a groove for the flange around the base of the cartridge to lie in. drawn back endwise in a direction to draw the base of the bottom cartridge away from below the other cartridges in the holder. Vhen the bottom cartridge is so drawn back,

' it comes opposite to a slot in the lower part of the front side plate of the holder. A fur- The slide can be ther backward movement of the slide causes two blades or fingers to be t-urned outward from the back side plate of the lower part of the holder to press against the bottom cartridge near its two ends, and to eject it fronr 55 the holder through the slot in the front side plate which the bottom cartridge is then opposite to. The blades or fingers at the same time come below the other cartridges in the holder and prevent them from dropping down in it until the slide is again brought back to its forward position. The magazine or holder is formed so thatit can be attached to the side of a breech-loading firearm. If the breech end of such fire-arm is opened by the drawing back of a bolt, a` projection upon the bolt is toward the end ofthe backward movement of the bolt caused to draw back the slide of the magazine above mentioned, and so to eject a cartridge from the magazine int-o the trough 7c or space in front of the breech-bolt each time that the bolt is drawn back, so that when the boltis again moved forward to close the breech of the gun the cartridge may be pushed forward in front of it into the breech end of the barrel. When the bolt is again moved forward to close the breech, the slide above mentioned at the bottom of the magazine is moved forward again to its former position by means of a spring. The lowest cartridge in the holder can then drop down onto it, and the same operations are repeated cach time the breech is opened. In a similar way with other kinds of breech-loading fire-arms the opening of the breech is caused to move back the slide of the magazine or holder each time the breech is opened, so as to eject a cartridge from the magazine or holder int-o the trough or space vbehind the open breech end of the barrel.

In order that my said invention may be most fully understood and readily carried into effect, I will proceed to describe the drawings hereunto annexed.

In the drawings, Figure 1 is a longitudinal section of a cartridge holder or magazine constructed according to my invention. Fig. 2 is a vertical transverse section of the same. Fig. 3 is also a vertical transverse section, but with the parts in the position they occupy on the ejection of acartridge. Fig. Li is a horiroo zoutal section taken through the lower part or base ofthe apparatus. Fig. 5 is also a horizontal section, but with the parts in the position they occupy on the ejection of a cartridge. Fig. 6 is again a horizontal section, but with the parts in an intermediate position. The slide has begun to draw back the lowest cartridge, separating it from the pile, but the blades or' lingers have not yet been moved to throw it out. Fig. 7 is a plan ofthe cartridge holder or magazine. Fig. S is an elevation of a similar apparatus, butso made that the upper part is readily separable from the lower part or base. Fig. 9 is a transverse section of the'same. Fig. 10 is an elevation, and Fig. 11 is a transverse vertical section, of the movable upper part. Fig. 12 is a section similar to Fg.'3, but representing the cartridge-holder mounted upon a bolt-rifle ot' ordinary construction. For this purpose the base or lower part of the cartridge-holder may be provided with a projecting tongue entering a socket proyided upon the rifle.

c a is the case, consisting of plates which receive the pile of cartridges between them. They are curved at the top, so that they have to be sprung apart slightly in inserting the cartridges, and the cartridges cannot afterward fall out. Y

b b are the grooves or rabbets adapted t receive, retain, and guide the flanges of the cartridges.

c is the slide receiving the bottom cartridge. Its head c has in it a groove, ciwhich, when the slide is in the position indicated in Figs. 1 and 2, corresponds with the rabbet b at the back of the holder, and when the slide comes into this position a cartridge drops down into it. The head of the slide c also has upon it a stud or projection, c, the stem of which passes through a slot provided for it in t-he lower part or base of the receiver. The slide also has a bottom plate, c, and this completes the slide.

d is a spring tending constantly to press the slide forward. This spring may in some cases be dispensed with.

c is the slot or opening at the lowerpart of the cartridge-holder` through which thc cartridge is ejected. Y

f f are the blades or fingers. They are hinged at Vthe back of the case, and have projections passing through slots in the bottom plate, C, and also through slots in the lower-j end kof the holder. The slots in the part c* are marked cf, and their form is such as to throw the blades f f outward in the latter part of the rearward movementof the slide. Then the lingers are thus moved forward, they eject the cartridge, as is indicatedv in Fig. 3, and l XVhcn the slide returns, the

fingers are drawn back and another cartridge drops down into the slide. This cartridge is securely retained until the next action of the slide, for it is not until the cartridge is drawn back that it can pass out of the ejecting slot or opening c. Until then the bullet end projects beyond the opening, and the ange of the cartridge is opposite a portion of the opening which is too narrow to allow it to pass.

Then the upper part of the cartridgediolder is made separate from the base, as shown by Figs. 8, 9, 10, and 1l, the upper part 'is formed with a rim, g, which is received into corresponding grooves in the lower part or base. A cover, h, is provided, which is pushed oli` in t-he act of sliding the upper part into its place. The ammunition may be packed beforehand in these separate cases, and theloaded eases s lid into place on the delivering-base as required.

Vhen the cartridge holder or magazine is mounted on the gun, as in Fig. 11, drawing back the bolt of the gun toward the end of its movement acts by a projection upon it against the stud c, and causes the delivery of the cartridge into the trough or chamber in front of the bolt. Thus when the bolt is next moved forward, this cartridge is pushed into the barrel, and in the last part of the forward movement another projection on the bolt pushes back the slides c.

Having thus described the nature of my said invention and the manner of performing the same, I would have it understood that I' claim l. The combination of the case having the cartridge-ejecting slot and the slide by which the iiange of the lower-most cartridge in the case is engaged, and by the actuation of which the cartridges are in turn moved endwise,

fianges foremost, and brought into position to be ejected, substantially as and for the purpose hereinbefore set forth.

2. The combinat'on of the case, the slide engaging the lowermost cartridge in the case, and the` blades or fingers connected with and operated by the slide for ejecting the lowermost cartridge in the case and supporting and retaining the cartridges above, substantially as and for the purpose hereinbefore set forth.

3. The combination of the case, the slide,

provided with slots, and the bladesl or fingers supported by the caserand provided with projections engaging the slots of the slide, substantially as and for the purpose hereinbefore set forth.
