T0 all whom it 'may concern:

Be it known that I, PAUL MAUsnr., of OberndOrfbn-the-Necliar, inthe Kingdom of Viirternberg, German Empire,have invented an lmprovement in Repeating Fire-Arms, of which the following is a full and clear specification.

The invention relates to that class of guns which are closed by a cylindrical breech-piece whose locking and firing mechanism is known under the name Mauser,77 and in which the eartridge-holdin g magazine is situated beneath and along the barrel.

The object of the invention is to furnish a device by the application of which to guns of the mentioned pattern these guns may be used at will either as repeating or as single-shot arms.

In the accompanying drawings, in which similar letters indicate like parts, Figures 1 to 8 represent a new gun constructed according to the present invention; Figs. 9 to 12, a modification of certain parts, and Figs. 13 and 11 show the application of the invention to an old gun of the so-calle( pattern 71.77 Fig. 1 is a longitudinal vertical section, the breech closed, Fig. 2, partly the same section, partly a side view, the breech opened; Fig. 3, a horizontal section from below, in the line A B C I) E ofFig. 1. Figs. 4, 5, 6 are cross-sections in the lines F G H I K L of Fig. 3. Fig. 7 is an elevation of the left side, partlyin section; Fig. 8, a horizontal longitudinal section ofthe extractor. Figs. 9, 10, 11, 12 show sections and views of some ofthe improved parts constructed differently from the same parts in the previous figures. Fig. 13 is a horizontal longitudinal section of a gun of the pattern 71, altered according to the present invention and with open breech; Fig. 14, a vertical crosssection in the line M N of Fig. 13.

The main feature of the improved arm is a cartridge-carrier, b, oscillating on its rear end and brought in action, when wanted, by the movements of the breech-piece or lock f. This carrier b. when standing in a downward inclined position, receives the cartridge c from the magazine arranged beneath and along the barrel, and delivers it to the barrel when lifted in an upward inclined position. The earrier Z) is lifted and depressed by the movement of the lockf, the front end of which serves as a breech-block, and which contains and coinmands the ringbolt. During thelifting motion of the carrier the next cartridge a of the magazine is stopped and retained by a tailpiece, h, of the carrier b. When the carrier b occupies its lowest position this cartridge is impelled by the driving-spring of the 1nagazine up into the scooped-out bed of the carrier b. The following cartridge is stopped by the projection d of a spring, e. Vhen the carrier Z1 is lifted it presses back the spring c by means of its swell m and liberates the cartridge, a1- lowing it to move to the tail-piece 71, which stops it again until the next depression of the carrier b.

On the rear of the carrier bis mounted a block, z', sliding up and down in a dovetailed groove of the carrier. Then the block t' is in its highest position its top portion, 7.', is rocked to and fro by shoulders or projections p and q of the extract-or o, which latter is fixed to the lock f and moves with it. This rocking ino tion causes the front end of the carrier I) to rise when the lock f is moved backward and the breech opened, and to fall when the loekf is moved forward and the breech closed. rIhe extractor o is not integral with the loekf, although it is attached to and moves with it.

-Being made separate, it is capable of removal and replacement, and when worn or injured it may be removed. Vhen the sliding block z is depressed, so that its top, 7.", is out ofreaeh of the shoulders p g, the carrier I) will not be moved*that is to say, the repeater is converted into a single-shot gun. It is important to stop the movement of the carrier b whenit is raised, forming in this position a smooth bottom in the chamber c best adapted to introduce into the barrel a cartridge when loading by hand. To accomplish these objects the sliding block z' is depressed by a pin, c, on the end of the shorter arm of a bell-crank lever, s, swinging round the screw-pin t. The longer arm of the bell-crank lever protrudes on the side of t-he chamber c, and is shifted into the scribed already above.

. which turn on the screw-threaded end.

2 esente required position by hand by means of the thumb-piece a of the arm s. The pinvworks in a horizontal slot of the slide-block t'. The shifting of the levei1 s, and thereby the depressing of t, is performed when the carrier b is in its highest position, when the block is drawn back for loading. rlhe sliding block i rests in its lowest position with its lower back edge against an offset, x, provided on the inside of the chamber or case c, so as to iixthe carrier Z) in its elevated position, prohibiting1 its being depressed until the sliding block t is again "raised, liberating at once the carrier b and transforming the single-shot gun again into a repeater.

The spring e is furnished beside the swell m in the front end with a second similar swell, n, on

the back end. rlhe latter exerts a uniform spring-pressure against the carrier b at its fulcrum g, while the swellm performsthesame duty as soon as the front end of the carrier b has left its lowest position. By this arrangement the movement of the carrier b is made smooth and easy. To show that, and also how the construction of the details can be altered without leaving the ground of the invention, a modification of those parts which control the movements of the carrier b is shown in Figs. 9 to 12. The slide-block is not guided by a dovetailed groove ofthe carrier l), but by a square one, and it is moved up and down not by a pin, but by the direct contact of the shorter arm t of the bell-crank lever. rIhis arm c works in a suitably-shaped recess of the block t', and swings, together with the longer arm s, around the screw-bolt g t, by means of which and of the coupled hubs g of the two levers c and s, these latter are united to a solid piece. The arm cworks on the left side of the gun, while the arm s protrudes on the right side, so that it can be moved to and fro by means of its thumb-piece u. In this way the slide-block il is moved up and down, presenting its top k to the shoulders l) and q of the extractor o, or bringing it out of reach of them, exactly as it is derlhe carrier b swings here not directly round the screw-threaded end, but round the hubs g t of the lever c s, rIhc recess of the block 13 is large enough to clear the hubs g in any position. By this construc- Such is The carrier Z) contains-in areces's at the rear. the sliding block i, the top 7c of which. works, when raised, in the groove of the lock f, in which works also the trigger-catch. The carrier b turns round the screw-bolt g t, which forms at the same time the fulcrum ofthe bellcrank lever c s. The pin of the short arm c works throgh a slot in the side of the carrier b, ina groove of the block t', which is allowed to rise and `fall. The extractor ois not altered at all in this construction, but is that of the old gun. I do not bind myself to one form of the parts.

I claim as my inventionl; In a repeating nre-arm with cylinder-lock, the longitudinally-sliding extractor o, having shoulders 1o q, in combination with the vertically-sliding block i, havingatop piece, k, and with the carrier b, substantially as shown and described.

2. In a repeating fire-arm with cylinder-lock, the bell-crank lever s, in combination with the vertically-sliding piece t' .76, moving up and down in ways on the carrier adapted to move it into and out of engagement with the shoulders p q, carried on the sliding lock f, as sh own and described.

3. 'Ihe offset x formed on the chamber C, in combination with the sliding piece t' working on the side of the carrier, and with said carrier b adapted to lock the latter in its eleva-ted position bythe depression of the slide-piece i, ,as herein specified.

4. The spring e, furnished with the swells n1, and a and head d. in combination with the carrier b of a repeating fire-arm and with the breech piece orlock f, as shown and described, and adapted for joint operation, substantially as set forth.

5. The carrierb, governed bythe slide-block t', acting in the rear end thereof to tilt it, and havingthe top piece, 7.4, on which act the shoulders 1) q of the extractor o, or the equivalent devices ofthe lockf, in combination with said lock f and with the spring e, with its swells m n andy head d, all working together 'as described, and for the purpose explained.

This specification signed by me this 5th day of February, lSSl.
