SPECIFICATION forming part of Letters Patent No. 245,048, dated August 2, 1881.

Application filed November 6, 1880. (No model.) Patented in France March 24, 1880, in Belgium March 80, 1880, and in Italy May 5, 1880. i

1'0 all whom it may concern Be it known that I, EDUARD BARTHELMES, residing at the city of Berlin, in the Kingdom of Prussia, German Empire, have invented Improvements in Magazine Attachments to Breech-Loading Fire-Arms, of which the following is a specification.

.This invention has reference to an improved magazine attachment to breech-loading fire- IO arms,by means of which a number of cartridges may be successively supplied to the barrel of the firearm in connection with the operating mechanism of the same, so that the loading of the same is simplified and a number of shots I 5 may be given in rapid succession.

The invention consists of a cartridge-case which is detachably secured to the stock of the fire-arm and provided at the inside with a guided and spring-pressed plate which forces the cartridges from one side to the other, so as i to discharge the same successively in connection with a hinged cap, which is set bysuitable lever mechanism either into closed or partially or entirely open position, as required, as

' will appear more fully hereinafter and finally be pointed out in the claims.

In the accompanyingdrawings, Figure 1' represents a sectional side elevation of a breechloading firearm with my improved magazine 0 attachment, the latter being shown in longitudinal section. Fig. 2 is a vertical transverse section, of, the fire-arm and magazine. Fig.3is a side view Fig. 4, a top view, and Fig. 5 a rear view, of the magazine attachment, shown detached from thefire-arm; and Fig. 6 is a vertical transverse section, on a. smaller scale, of the fire-arm and magazine, showing a modified construction of the attachment.

Similar letters of reference indicate corre- 4o sponding parts.

Referring to the drawings, a represents a casing of sheet-steel, which is preferably bent in the shape of the letter U, so as .to be capable of convenient and. compact attachment to 4 5 the stock below the chamber 6f the barrel without taking up any extra space or being in the way. The opening on the left side of the U-shaped casing a is permanently closed by a top plate, I), the overlapping ends of which are secured by screws, as shown in Fig. 5.

In the interior of the casing a is arrangeda stron g spiral spring, d, the upper'end of which is seated against the top plate, I), while the opposite end bears against an angular slide-plate, cl, which corresponds in size to the cross-section of the casing. The spiral spring dis made of such length and strength that it is capable of forcing the angular slide-plate 01 through theentire length of the U-shaped magazine up to the right-hand opening of the same.v

7 The slide-plate d is provided with a'fixed stud, d which passes througha transverse slot 0 is provided with a side recess, h, into which the stud d of the slide-plate d is placed when the slide-plate has been carried back sufficiently to that side of the casing.

I Before the stud of the slide-plate d can be set into the recess h of the slot 6 it is'neces-. sary to push a pivoted guard, s, sidewise, after which the stud of the slide-plate can enter into the recess h, as shown in Fig. 4. The spiral 8o spring d is thereby reliably retained by the slide-plate in compressed position at one side of the magazine, in which position the interior space of the casing a may be'readily charged with cartridges. 8 5

The front and rear end walls of the magazine a are provided at the right-hand side with bracket-shaped extensions or ears on, to which a'semicircular cap, 0', is hinged by a pintle, k; This cap is adapted to cover the right hand 0 opening of thecasing a, and is made, like the body of the casing, witha taper, which corresponds to the usual taper of the cartridges used in breech-loading fire-arms.

- The semicircular cap '5 can be set into three 9 5 diiferent positions, and securely, retained in of the casing, by which slot the .ward motion of the lever-arm Zis controlled.

either of the same by means of two pivoted retaining-lever arms, oand l, which are clearly shown in Figs. 3, 4, and 5. The pivoted arm I, Fig. 5, turns around the sorew-stud m, and projects by apin into a slot, 11, of the rear wall extent of up- In similar manner the lever-arm turns on a screw-stud, p, and passes by a pin, q, through a slot, r, of the rearbracket-plate, a of the easing, the slot '1' defining the extent of side motion .of the lever-arm 0.

For placing the cap 2' into the first or closed position the lever-arm lis left in its downward position, and the lever-arm o carried toward the left, so as to abut against the projecting hook-shaped end of the lever-arm Z. In this position the arm 0 retains'the cap '5 in closed position.

I the right as far as the slot 1' admits, in which position the shank 'v of the cap abuts against the pin q and produces the partial opening of the cap '5, as shown clearly in Fig. 2. When the cap '5 is closed the cartridges are securely retained within the casing, but ready to be charged into the barrel of the fire-arm. In this position'the stud of the slide-plate is released, so that the latter is forced by the spring upon the cartridges, and moves them forward against the cap 7:, which receives thereby atendency to be thrown open, which, however, is prevented by the pin got the lever-arm o. By throwing the lever-arm o sidewise the cap 2' is instantlythrown into the third or partially open position by the pressure of the spiral spring, until its shank 0 forms contact with the pin q. The-cartridges follow the motion of the cap, the upper one being partly embraced by the semicircular cap a, the lower shorter part of which, below'the shank r, enters between the first and second cartridge, and prevents, thereby, the latter, as well as all the remaining cartridges, being thrown out of the magazine by the pressure of the spiral spring. In thisposition of the cap t the uppermost cartridge is readily dropped sidewise into the open barrel of the firearm. By pressing the cap t downward the lowershorter part of the same forces the cartridges slightly downward, and permits the uppermost cartridge again to pass beyond it and place itself in position in the upper longer partof the cape, so that by resetting the lever the next cartridge can be thrown out and the remaining ones held inside'of the magazine. By thus opening and closing thecap c" one cartridge after the other can be successively and reliably supplied from the magazine to the barrel of the fire-arm.

The magazine a is attached to the stock of the fire-arm by means of a dovetailed piece, t, which is rigidly screwed to the under side of the stock.

From the inner wall of the magazine are bent up two lugs, sides of the dovetailed piece t, which lugs are slid over the piece so as to retain the magazine against lateral displacement. A band-sprin g, t, is, furthermore, centrally riveted to the inner wall of. the magazine andextended longitudinallyalong the same.

The spring t is provided with hook-shaped projections t t, which enter into notches of the fixed dovetailed piece t, so as to prevent nal direction when once placed in proper position on the stock. If'a smaller number of -cartridges is desired to be stored in the magansed, which is locked to the side of the fire-arm, though the U-shape form is in every respect preferable, as it is more compact and does not interfere with the handling of the fire-arm- A For charging the magazine with cartridges the cap t is thrown into entirely open position and the slide-plate (1 locked into the recess of the slot e. The cartridges are then inserted and the cap 2' closed whenthe magazine is encan be carried in any desired manner detached from the stock until required for use. It is then looked to the stock of the fire-arm, after which the spring at is released and the guard s carried over the recess h, so as to prevent the accidentalresettin g of the stud of' the side plate in the recess h.

The breech-loading fire-arm may be supplied for any length of time with single rounds from order for rapid firing is given, when the magazine is placed in position on the stock. The

release the cap 6, which is, however, held in closed position by the lever-handle of the movable portionof the chamber of the fire-arm. By turning the handle of the chamber from right to left the shell of the cartridge is first thrown out by means of the extracting devices, which are indicated in Fig. 1, respectively, by the letters A and B, the extractor Aen gaging the shell and carrying the same back within the chamber until the rim of the cartridge is. arrested by the fixed projection B, by which the cartridge is upset and thrown out of the chamber. As the pressure of the handle on chamber the cartridge is placed in properposition into the chamber of the fire-arm and the the cap 0' is thrown of the. cartridges,

the same is turned over from the left to the right.

lever-arm 0 is then carried sidewise, so as to I t, at the same inclination as'the any displacement of the magazinein longitudizine, the straightform shown in Fig. 6 may be tirely filled. In this condition the'magazine ice I 0 the cartridge-box in the usual manner, until the the/cap t is released in opening the chamber,

cap t closed againby the lever-handle, when i 3 The magazine shown in the drawings is capable of taking up eleven cartridges, which,

in connection with the cartridge in the barrel, furnish twelve rounds, which can be rapidly fired one after the other by the simple opening and closing of the cartridge-chamber of the barrel by the handle, without removing the hand therefrom during this operation. manner the fire-arm is almost instantlyreloaded, and admits the firing of a dozen shots in rapid succession. The magazine is removed from the stock by simply pressing with the hand upon the bottom of the magazine, so that the locking-spring may be released, and the r magazine detached from the stock.

Having thus described my invention, Iclaim as new and desire to secure by Letters Patent- 1. A double-wall magazine open at one end, and at this end provided with a concave hinged and tapered cap, 1', recessed at u, in combination with lever-arms lo, the arm I hooked and provided with a pin working in a slot of casin g a, and the arm 0 provided with a stud work- 2 5 ingin a slot through the rear breech-plate, a,

said parts being arranged to operate substantially in the manner and for the 'purpose specified.

2. The combination of a double-wall maga- 0 zine, having a transverse slot, a, in its outer wall and apivoted guard near the enlarged end of the slot, with an interior guided and In this spring-acted slide-plate having an exterior button, snbstantially'as described.

3. The combination of a double-wall cartridge-magazine, having inwardly-bent lugs I and a central longitudinal locking-spring at its interior wall, with a fixed holding-piece of the block, the spring locking by projections .into notches of the fixed piece,-subs tantially as described.

4. The double-wall magazine slotted at e h, and provided with the guard, slide, and stud, in combination with the hinged cap 43 and-its releasing and retaining devices, substantially as described.

5. The combination of the casing a, having end brackets, hinged cap 2', having corner recess u, and pivoted lever-arms o l, which are guided by studs in slots u and r of the casin and end bracket respectively, substantially as described.

6. The semicircular cap *5, adapted to fit the' cartridges,and having a shank, a, by which it is pivoted to the casing at k, in combination with a magazine, a, and a stud, g, on the lower arm, 0, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses. V
