BWL ARM WITH TUBULAR CARTRIDGE MAGAZZINI.

' Application mea Augm 24, 1,925. serial no. 'sama To all lwhom it may concern.'

Be it known that I, HANS ScHMEIssnn, a

' citizen of Germany, residing at Philosophenweg 5, Suhl, Germany, have invented certain new and useful Improvements in Small Arms with Tubular Cartridge Magazines, of which the following-is a specification.

My invention relates to improvements in small arms having a cartridge magazine formed in a known manner as a tube or sleeve located along" the barrel. As the cartridges are moved out of the magazine singly by means of a springenclosed within the tube or sleeve, they willl be received by and on the usual cartridge carrier acting to bring, when swinging upwards, the cartridge to a position right opposite or in front of the chamber.

The chief object of my invention is to provide improved means for` pushing the cartridge from the raised carrier into the chamber by means of a bi-partite breechbolt having the one of its two parts dimensioned and arranged as to be capable of entering from the rear into the tubular front end of the cartridge carrier in which the lifted cartridge lies, in order to push 'the cartridge forward into the chamber of the barrel, and to be further adapted to disengage from the 'tubular front end of the carrier upon the subsequent downward movement of the latter, while the other part of the breech-bolt will be retained in its rear position during the thus accomplished charging operation and will not advance to also .engage the bottom surface of the cartridge in the chamber, until the 'carrier has moved down and out of the path of the -breech-bolt, to receive a next cartridge.

Preferably I construct the second mentioned part of the breech-bolt to constitute at the same time a-i'iring pin or similar formation.

A further object of my invention is to provide means for reventing the firing member which is comlbined, as hereinbefore stated, with the one part of the breech-bolt, from accidental firing of a shot. The said part of the breech-bolt is retained in `cocked position byf means of a suitable pawl. B mounting the latter on the detachable cover of the breech casing' on which also the bipartite breech-bolt is mounted, accidental firin in case of removing the cover and if the member is in cocked position` andr au cartridge in the chamber, is' eiiiciently prevented.

The invention further comprises a locking means on the ldetachable cover for retaining the two parts of the breech-bolt and preventing the same from being' ejected from the casing by the `action of the closing spring and the firing spring, in case of removlng the cover from the casing. In order to enable the cover .to be readily removed frein the casing, suitable ribs may be provided at the fore end and at the rear end thereof, adapted to engage in correspondingly shaped grooves provided in the wall of the casing. If desired another locking means may be provided on the-cover for the 'loy purpose of preventing the cover from ac? I cidentally removing from the casing or, in other words, holdin seated with its ribs 1n the said grooves of the casing. l

l The invention further comprises a closlng lever mounted on the right-hand side or on the left-hand side of the-breech-bolt so as to be able to be moved 4or swung in a the -cover ro er1 vertical plane, a lateral recess or slot. beingf providedin thel casing or in the cover for receiving and guiding the lever which p'refv -erably is shapedy to form a handle aording a readyv means for causing the'lever to engage inv-a suitable recess or withJ a projecting part ofthe casing or the cover, ifl required, so that the breech-bolt ywill be rmly locked and the weapon may be used for firing single shots or. repeated shots. l

The invention furthermore comprises the constructions and combinations of parts hereinafter particularly described and illustrated in the drawings.

In the accompanying drawin forming a part of this specification, and s owing for purposes of exemplication, a preferred form and manner in which the invention vmay be embodied and practised:

igure 10 is an elevation of the breechbolt with the closing lever pivotally attached thereto;

Figure 1.1 is a lever and Figure 12 is a side view and a plan view of a detail.

Referring to Figures 1 to 3 the casing 1 is .firmly connected with the barrel 2 and the tubular cartridge magazinel 3 in the usual manner and'thetwo parts 4 and 5 constituting the breech-bolt are mounted in the casing 1, as shown, subject to the action of the two coiled springs 6 and 7, respectively. At the front end of the part 4 of the breech-bolt a cartridge extractor 8 is pivotally mounted in the usual manner, whilst the front end or face of the part 5 of the breech-bolt is shaped to form a firing pin 5a. 'When the parts 4 and 5 return from the closing position shown in Figure 1 to the op'en position illustrated in Figure 2, the part 5 is taken along with by a shoulder 4c of the part 4.

The cartridge carrier 10 is mounted in plan view of the closing the casing to swing about a transverse pin 9 or the like. The front end of the carrier is shaped to form a. tubular seat 10a for the reception of the cartridge to be transported from the magazine tothe chamber. This tubular end of the carrier is recessed to be open at the top and at the rear, as shown at 10b in Figures 1, 2 and 4, but the recess 10b is only so wide that a cartridge cannot pass therethrough, whereas the part -1-` of the breech-bolt can freely pass therethrough. The part 4 of the breech-bolt is provided with two lugs projectnig dowward from the bottom side thereof, the one lug 4b being at the rear end ot the vpart 4 and the other one, 4a, being located at a point intermediate between the two ends of the a-rt 4. Then the latter moves backward) towardsthe butt, the lug 4"L will engage the short arm 10c of the cartridge caiprovided for the pu rier and cause the longer arm of the carrier to rise and to thereby bring a cartridge into a position in front of the chamber, as shown inFigure 2, and when the part 4 moves forwards towardsythe barrel, the lug 4." will engage the arm 10c of the carrie-r 10 and cause the longer arm thereof to descend from the position illustrated in Figure 2 to that shown in Figure l.

Pivotally mounted on a' pin 12 in the casing is a pawl 13 which will lock thc'part 5 of the breech-bolt, when in the full opengor rear position, by catchin into a notch 5" 1n the bottom face of the rear end of t e part 5. As hereinbefore stated the front arm of the carrier 10 is raised by the action of the lug 4a when the breechbolt moves backward or towards the butt, so that the tubular end 1tl of the arm will bring a cartridge from the magazine to the chamber of the barrel 2, see Figure 2. When subsequently the part 4 of the breech-bolt is moved in opposite direction or towards the barrel, the .said part 4 will pass from the rear end through the recess 10b into the tubular vscat 10i of the carrier and push the cartridge out of the sea-t 10a into the chamber of the barrel` as will be clearly seenl upon inspection of Figure 3. At the very moment the cartridge has come out of contact with the carrier the lug 4b of the part 4 will engage the short arm 10c Aoi. the carrier and'cause the latter to turn about its pivot 9 t-hereby lowering the front arm of the carrier into the position illustrated in Figure 1, so that the tubular fore end 10a of the arm will be in readiness for the reception of' a new cartridge .by the pawl 13 engaging in the notch 5" and is locked until, upon firing, the pawl 13 is moved to release the part 5 which then is rapidly thrown forward by the action of the f compressed spring 7. in order to cover that portion of the bottom face of the cartrid e 1n the chamber whlch is not covered or y1n contact with the fore end of the part 4 of the breech-bolt, and to cause at the same time the firing pin 5a to hit the cartridge in the chambe Referring to Figures 5 to 7, 1 denotes the stationary casing. The barrel and. the cartridge magazine are not shown -in Figures 5 to 7, but they are of usual constructions and arrangement as hereinbefore stated with reference to Figures 1 to 4. The bipartite breech-bolt comprising a closing member or part 4 and a firing member or part 5, as before, is mounted on the cover or cover plate lsL so as to be capable of moving backward and` forward. The cartridge extractor 8v is provided, as before, in the fore end of the part 4. The locking pawl 13 pivoted on a pin 12 secured in the cover 1a isfactuated b a spring 13a causing-the pawl to catch into the notch 5b of the part 5 and to lock the latter in the position shown in Figure 6, when the breech bolt is moved into its 'extreme hind position.

In the fore-end of the cover 1a and on the inner side or face thereof .a T-shaped groove is provided for the reception of a locking latch shaped to correspond to the shape of the groove so as to be slidable therein. The groove and the latch' are located transverse to the length 'of the cover and a spring 15 normally holds the latch in a raised position so that its upper end lies in the path of the breech-bolt whereby the two parts of the latter are prevented from being ejected over or out of the front end of the cover if the latter is to be removed from the casing.

Further the fore end and the rear end of the cover are equipped with ribs 11 adapted to engage in correspondingly shaped grooves of the casing 1. Furthermore a horizontal bore is provided in the rear end of the cover to accommodate a latch-bolt 14 havingr a lateral knurled head 14". The rear or free end of the bolt 14 normally lies in a recess 14a of the casing under the action of a spring 14c abutting against the fore end of the bolt, as will be clearly seen in Figures 5 and 6 whilst Figgure 7 shows the parts in section.

Referring to Figures 8 to 12 showing the casingl viewed from the other side, the sliding breech-bolt 4 is located either in the casing 1 or on the cover 1' and a coiled spring 6 is provided for moving the same into the closed position, that is towards the barrel not shown. The longitudinal slot 1c is enlarged and shaped to afford a locking face 1dl lying in an arc of a circle the centre of which is in the pivot of the breech lever 16. When the latter is turned downward the arm 16c will engage behind the face or shoulder 1d so that the breech-bolt will be locked.

For the purpose of yieldingly securing the lever 16 in its two limits or end positions I utilize the`main spring 6. To this end I provide in the lrear end of the lever 17 two notches 16a and 16b and I mount onto the free end of the coiled spring 6a a tiring bolt 17, shown separately in Figure 12 and having a tooth 17a adapted to catch, under the pressure of the spring 6,

either into the notch 16a or into the notch 16D, depending upon the position of the lever 16, so that the latter will be resiliently fixed in either position. The bolt 17 has a vertical bore 17b of elon ated or elliptical cross-section and I provi( e a vertical pin 18 passing through thev bore 17b in order to guide the bolt.17 in vertical direction.

I have not attempted to explain all of the details of the construction of the fiile,

construction yand relationship and will `be to the tenets of small-arm construction.

It seems unnecessary to reiterate the o eration of the rifle, for4 the operation o the improved parts has been described indeproperly -mounted and supported according tail and the operation of the parts which are old and not shown is known to persons skilled in the art. Nor does it seem nec- -essary to burden this specification with an exposition of theadvantages which the invention possesses, for they will be ap arent to .those versed in the art to whic this invention relates.-

It is also apparent that in carrying out my invention some changes from theconstruction hereln shown and described may be made.

but hold myself at liberty to make such departures therefrom as fairly fall within the spirit and scope of my invention.

What I claim is 1. A repeating rifle of the type described comprising a casing; a cover having a groove; a breech bolt-in said cover having a closing member and a firing member; a spring-pressed locking pawl ivoted in said cover adapted to hold the firmg member in cocked position; alocking latch adapted'to slide in said groove; and means in the cover adapted to engage in the casing.
