Application mea september 1o, 192,0. serial no. cassa To all 'whom 'it may concern:

Be it known that jI, JOSEPH DECLAYE, a

subject of the Kingof Belgium, andresid'ent,

of Liege 32 Rue Adolphe Borgnet, Belgium, have invented certain new` and useful Improvements in or Relating to Cartridge Stop Levers for Tubular Magazines of Small Arms; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, -referencebeing had to the accompanying drawings, and to letters or figures of reference marked. therein, which formapart of this specification This invention relates'to a cartridge stop lever for tubular magazine of 'fire arms, which is actuated' by thel motions `of the breech bolt so as to cause the checking vof the cartridges and their releasing. i.

According to the invention the bolt is provided with a groove which may engage the end of a finger of the stop lever. The motions of the vbolt cause therotation of the stop lever by the engagementand disengagement of the end of said finger in the groove of the breech bolt.

In a particular form of the invention the stop lever is pivoted under the bolt and has at each end a nose for checking the cartridges, and works in such a way that when the front nose is releasing a cartridge, the rear nose, although it allows the passing of a second cartridge pushing the first, checks the third cartridge, thus relieving the lirst and second cartridges from the action of the spring.

The accompanying drawings illustrate an application of the invention.

In these drawings:

Fig. 1 shows the positions of the parts when a cartridge is engaged in the breech ready for firing;

Fig. 2 shows the positions of the parts when the breech bolt which is recoiling has brought about a rotation of the cartridge stop lever; 1

Fig. 3 shows a position of the parts similar to the position shown in Fig. 2 but when the stop lever is releasing one of the last cartridges of the magazine; and

Fig. 4 shows adetail in front view and in section.

under the action of a spring Tacting onlan arm 8 of the 'said-lever 1. This leverv ispro.- vided with'a finger 5 always kept against the breech bolt by the action of the said spring 7 and becomes engaged in agroove 6 ofthe bolt, when said :bolt has-,sufciently recoiled.

When the end Vof the finger 5 engages the groove 6.of the bolt, the lever 1 .is dis; placed and the nose 9' provided at `rits front end releases the cartridge 10 which was -held nearer in the position illustrated in Fig. 1. The. j

spiral spring 15, shown in Fig. 3 acting on the cartridges in the magazine, then thrusts the cartridge 10 forward, together with the whole column of cartridges. VWhen tliefcarf tridge 10 is in a position such that ity may 4be pushed forward intofthe breech by thefront part of the .breech bolt, this cartridge-10jA is isolated from the pushing action. of` the spring 15.V This isolation is` obtainedby. the nose-14 provided at the rear end of thelever 1 engaging the rim o f the cartridge12.

In order that thetwo lastv cartridges may be properly moved outfof lthe magazine, the

eXtremityofV-the springl constituted off-a flexible rod 16, is provided with two

projections

17 and 18 distanced from each other by the length of a cartridge. rIhe first pro* jection 17 is distanced from the end 20 of the said flexible rod 16 also by a cartridge length. Thus, when the last but one cartridge 12 is within the reach of the breech bolt, that is in the position of the cartridge 10 of'Fig. 2, the nose 14 isolates the said cartridge from the action of the spring 15 by checking the projection 17.

When the last cartridge (13) is in the position of the cartridge 10 of Fig. 2, the nose 14 checks the projection 18. When finally the breech bolt comes forward again, thus causing a further displacement of the. stop lever 1, and the pushing of the cartridge 13 in the breech, the nose 9 of the lever 1 checks-the projection 17.

The inserting of cartridges into the breech is facilitated by a slope 19 arranged at the `in Fig. 4. These pieces are arranged at suitable places, between two turns of the flexible rod 16. i

While the invention has been illustrated in what is considered its best application it may have other embodiments without departing from its spirit and is not therefore limited to the structures shown inthe drawings.

VVhatfI claim is:

l. A cartridge stop mechanism,compris ing the combination with a tubular magazine for the cart-ridges and a breech bolt having av groove therein, of a stop lever adapted to act upon the cartridges in said magazine, said lever being provided with a finger arranged to engage in the groove in said bolt, said breech bolt being arranged to actuate said stop lever to stop and release the cartridges, the movements of the-stop lever being caused by the movement of vsaid nger into and 'out of said groove and said groove being located in the front portion of said breech bolt whereby a cartridge is released only when said bolt is in its rear position.

2. A cartridge stop lever for` tubular magazine actuated by the movements of the breech bolt so as to cause the checking of the cartridges and their releasing provided with a finger the top of which may engage in a groove of the bolt, the rotations of the stop lever being caused by the extremity of said finger oing into the groove of the breech bolt an out of it, this .stop lever having its two ends provided each with a nose for checking the cartridges and operating in such a way that when the front nose is releasing a cartridge, the rea-r nose, although. it allows the passing of a second cartridge pushing the iirst7 checks the third cartridge thus causing the second cartridge and consequently the first to be isolated from the action of the spring of the magazine.

3. A cartridge stop lever for tubular magazine actuated by the movements of the breech bolt, the two ends of said lever being provided each with a nose for checking the cartridge and the spring of the magazine acting on the last cartridge by means of a flexible rod provided with two projections distanced from each other of a cartridge length the iirst projection being distanced from the end of the saidlexible rod also of a cartridge length, this device operating in such a way that the last two cartridges may regularly go out of the magazine.

il. In a cartridge stop magazine, the combination'with a tubular magazine for the cartridges7 of a movable stop lever, the two ends of which are each provided with a nose 'tor engaging the flange of a cartridge and a breech bolt controlling said stop lever to release the flange of the cartridge when the breech bolt is in its rear position.

In testimony whereof I aiX my signature in presence of two witnesses.
