To all whom z'wnay, concern."

Beit known tha-tl, F 1min FEEDERLm citizenl'ofv the Germ-an Republic,` residing at Obernd'orf-on-the-NeckanL Germany, 'ha-ve inventedvcertain new and useful Improve-k ments in ;Magazine. Rifles'` of Small Caliber', of which the .following is: ay specification.Y

My invention relates to a magazinerifle ofasmall caliber andy providedwith al bolt breech Imechanism.

The'primary lobject'of myinvention is to provide awrile' ofthe above'indicated type that is extremely1 simpleI in construction, strong: and durable. 'and yhighly 'practical 'ins asmuch as disturbances'or,accidents such as jamming.' ofthefcartridges-or the like are reduced to a wminimum,`

Another object'fof my invention yis to yprovide improved means' for vafreadyv change of the magazine and for af high:y degree: of safety. Various other objects and/advantages will become apparent during. the course of the; following description.

These objects are accomplished by such means as arezshown'in their preferredfform in thewaccompanying drawings,A described in the following specification: and thereafter more specifically pointed out inthey appendedy claims In1the accompanying` drawingswherein like characters designate like parts through-y out the'several views:

Figure `r1 is' a--partial vertical longitudinal section of a rifle with the firing rod cocked;

Figure2 is an :endview thereof; Figiire is a'bottom-fview ofthebolt; Figures @and 5 lare sectional'viewson fthe lines 'IV-JV andv V-V, respectively, ofFigure 3.; Figure-61s a side'fview ofthe: casingor sleeve; Figurel 7 is a' section 'onf f the'fline-VII-V-H ofV Figl-` ure 6; Figure 8 isy atopfview ofthe'fbolt and the firingr rod n casing,y connected therewith; Figure 9 is a partial vverticalV longitudinal section of thezrie' :with the breech Vopenedv Figure 1() isa section'ontheline X-X in' Figure 9; Figure 1111s aside-'elevation offthe magazine', partlyy in section; l.`igurev 12 is a@ topi view thereof and Figure/"13 illustrates-fina similar view 'a detailof the mazazinegFigurev-` 14:y isi` ai partial vertical longif l tudinalsection'of the rifleV to illustrate "the particular construction of the safety mechanism, showing' the latter in they open or 'firs ing-position and Figure 15 is a similar view showingt'he safety mechanism in the lockingor safe position; Figure 16 is across section taken' on the line XVI-XVI of F igure 15; and, Figures 17 to 19 are views of the safety device separately, Figures 17 and 18-being side views and Figure 19 a sectional view thereof. The frontk portion-of the bolt 1 is of an essentially smaller diam--` eter than the rear portion thereof, two longitudinal parallel recesses 2 and 8 being cut in the wall of said front portion with their inner-endssloping into the outer face of the bolt. Intermediate the two `recesses 2 and 3 aI ridge lis formed at the bottom side of the bolt, saidridge being adapted to projectbetween the lateral lips 5 of the magazine 6,'- when the bolt is yin its Vretracted oropen position, as will be Clearly understood from an inspection of Figures 9 and 10. It will be seen; that the lips 5 of the magazine 6 engage in the recesses 2 and 3,r so that the upper rim of the magazine and the uppermost cartridge therein lie in the closest possible proximity to the' axis ofthe barrel. lnthis manner a means `is provided forreadily and properlyintroducing the cartridge into the cartridge chamber offthe barrel.

The casing or sleeve 7, Figures (Sand '7,' in which the' bolt'y 1 is guided duringV its -re'- ciprocal movements for reloading the-rifle, is closed at the top. and has, as usual, in thev forward end of its `right'hand wall an openin-g 8`for the ejectionof the spent cartridge shells anda longitudinal slot 9 terminating in an 1 enlarged rectangular opening. 10 :for loc-king; purposes. handle 11 of the bolt'assumes a horizontal position, as shownin dotted linesliniF'igure 10,- a-nd. insuch positionvthefl handle is in alignment with thee slot 19,' soth'atthe breech canbe opened vin the usual mannerby with; drawing'the boltL by means'of thehand'le: Then locked, however, the handle 11 assumes thedepending position shown in Fig-k ure 2,A engaging in the rectangular' opening; 10.-v Owingto this construction ofthe'casingi or sleeve 7 with an uninterrupted plane upper face any suitable means for the attach ment of a field glass or other appropriate sighting device may be readily applied thereto, if a field glass is affixed at the top of the sleeve the opening and closing of the bolt will not be obstructed thereby.

The portion 14 of the bolt is provided with a longitudinal lug or rib 15, as will be seen in Figures 2 and 8, extending over the whole length thereof. Then the breech is closed the said lug 15 engages in the slot 9 of the sleeve to the full of its length, but even when the breech is opened the lug still remains in engagement thereinto a certain extent, so that the portion 14 and the firing mechanism located therein are prevented from being rotated. Y

The magazine 6 of the rifle has the rear bottom corner shaped to form an incline 16, Figure 11, adapted to co-operate with a correspondingly inclined face of the pivotally mounted magazine holder 17, Figures 1 and 9. rl`his construction permits the magazine to be removed from the rifle by simply drawing or pressing the same backwards towards the holder 17 since the latter then recedes so that the co-acting faces disengage andthe magazine will be free to drop out of its housing. f

The holder 17 is provided with a spring acting' in such a manner that the lips 5 of the magazine, when the breech is opened, will be forced to engage in the recesses 2 and 3 of the bolt, whereas when the breech is closed, that is to say, when the bolt 1 is caused to advance from its position shown in Figure 9 towards the left-hand side, the magazine will be free to escape downwards, as soon as the rear sloping ends of the recesses 2 and 3 pass over the aid lips 5 and the latter come in contact with the unrecessed smooth face of the forward portion of the bolt. `When the parts under consideration assume this position the bolt can be turned so that the handle 11 will be brought into locking engagement with the forward wall of the opening 10, Figure 7, in order to adopt the position shown in Figure 2, irrespective of the recesses 2 and 3 which cannot interfere. At the operation of opening the breech the magazine is automatically lifted by the spring-actuated holder 17 into its upper position with the lateral lips engaging in the recesses 2 and 3 of the bolt.

The lips 5 of the magazine are so constructed as will be seen in Figure 12, that the mouth formed between them decreases in width towards their forward ends. The result thereof is that, particularly if rimlire cartridges are employed, the uppermost cartridge, in ascending into the sleeve or casing 7, Figure 9, assumes a gradually more and more inclined position with respect to the cartridge chambercf the barrel, since the rim of the cartridge, in moving forwards between the two lips 5, is lowered more and more owing to the decreasing width of the mouth. In this way a high degree of reliability is ensured in driving the uppermostcartridge into the chamber of the barrel and the danger of jamming is reduced to a minimum.

Obviously, if rim-fire-cartridges are employed the lower cartridges in the magazine necessarily must lie in a more declined position than any upper ones. In order to avoid any undesired play or clearance which would Vresult in. causing the cartridge rims to not lie properly super-posed one over the other, the magazine is given a tapered shape, that isto say, it is, as regards its width, smaller at the bottom than at the top, as will be clearly seen from Figure 11. In order that the rims of the cartridges in the magazine may lie in `front of each other, the magazine is given a par icularly inclined position in the rifle.

The carrier 18 of the magazine is shaped to form a shallow cavity 19, which is of a depth increasing freni left to right in Figure 13. The ridge 2O formed at the right-hand end serves the purpose of holding the rims Vof the superposed cartridges, at least Vin the lowerpart of the magazine, a little distance apart from the end wall thereof, yso that, friction between the cartridge and the magazine wall vwill be avoided. Owing to this `fact a relatively light spring V21 may be employed whereby the operation of refilling the magazine with cartridges will be facilitated. y

As will be seen in Figure 11 the carrier 18 is pivotally connected with the spring 21, preferably by bending the upper end of the spring inwards to form the pivot, so that the position of the cartridge carrier 18 will automatically be accommodated to the variations in the direction or relative positions of the lowermost cartridge in the magazine. The direction of the inclined bottom of the magazine corresponds or isadjusted to the position of the lowermost cartridge in the filled magazine.

The safety device for locking the trigger and the bolt in their cocked position is shown in Figures 14 to 19.V The device comprises a slide 22 having a knurled thumbpiece. The said slide is mounted on the left side of the rifle adjacent to the scar 23 of the trigger-mechanism and adapted to be shifted lengtlnvise. .as shown in Figures 14; and a spring-eontrolled locking pin is provided in connection with the slide 22 and the pin is adapted to engage in one or the other of two notches provided in the sleeve, just as the device is put safe or not.

The slide 22 has a longitudinal slot in engagement with a stationary pin and is provided at its fore end with a projection or tooth "24 adapted to rest upon the lSear 23, when-the slide is set sa'fej and to thereby lock the said sea'r and the trigger, as -will be seen in Figures 15 and 16. Then the parts have assumed the described positions a nose 25 projecting from the slide 22 upwards in close vproximity to the projection 24, engages in a recess 26 in the bolt so that the latter likewise will be locked by the slide. The slide is mounted and located in the rifle in such a manner that any pressure imparted to the trigger either accidentally or on purpose cannot cause the trigger or the bolt to be released, when the slide is set safe or in locked position.

A further safety arrangement provided in the rifle consists in a means by which the trigger, if the bolt is not fully locked, will be iiXed and unable tov be moved. To this end the bolt is provided with another recess or groove 33, Figures 3 and 16, adapted to receive a nose 34 integral with the sear 23 when, and only when, the breech is duly locked as shown in Figure 16. In all cases, however, where the bolt is not correctly locked the nose 34 is in contact, or approximately so, With the peripheral face of the bolt, so that the sear and consequently the trigger cannot be actuated. It will be seen that ring is impossible unless the bolt is completely locked.

Mounted in the bolt is the firing pin 27 having a spring 28 coiled about its rear end to hold the pin normally in a retracted position, as shown in Figure 1. The front end of the spring 28 rests on the bottom of the bore in which the springy is housed, while its rear end is in contact with a disk 29 rigid With the pin and abutting against a nose 30 of the extractor 31 as shown in Figure 1. The spring 28 is more powerful than the spring coiled about the Hring rod 32 so that, after the firing impact, the spring 28 acts to force back the rod 32, against the action of the spring` coiled thereabout, until the disk 29 again is in contact with the nose 30 of the extractor and the pin 27 reassumes its normal position, as in Figure 1.

It is apparent that in carrying my invention into effect some changes from the construction and arrangements herein shown and described may be made. I Wish it therefore to be understood, that I do not limit myself thereto, but hold myself at liberty to make such departures therefrom as may fairly fall within the spirit and scope of my invention.

What I claim is 1. A small caliber bolt-breech rifle of the magazine type, comprising a sleeve or casing, a bolt slidably mounted in said casing and having formed in its bottom face, two parallel longitudinal recesses which extend from the front end thereof a certain length and then gradually merge into the periphsleeve Aformed at onesidewitha ongitudinal slot which is Avopen' at one end and is enlarged at-its other end to form a locking seat, a bolt slidable in said sleeve and enibodying a Afront portion of smaller diameter than the rear portion, a longitudinal rib on the side face of the rear portion of the bolt adjacent said slokt to slide therein, and a handle on said bolt in advance of said rib likewise'adapted to slide in said slot and to be turned into said seat to lock the bolt against movement; substantially as described.
