Definitions

  • the present invention has for its object a- .device by means of which it. is possible to perform, with'an automatic firearm, a semiautomatic fire, that is'to say, a fire during whichv several operations are performedby hand,v in. order to diminish the-rapidity of thefire without however imposing upon'the shooter fatiguing efforts.
  • the eompl ressed-epringg may alsoser'veas a buffer in order to limit the recoil of the breech bolt.
  • Fig. l is a side view, partially in section, ot a firearm provided with the device for the semi-automatic fire.
  • Figs. 2 and 3 show respectively a top view and aside view of the device on an enlarged scale.
  • Fig.7 asa view of a part shown sep arately.
  • Fig.5 is a partial...sideview showing severalinterior parts of the device.
  • the firearm comprises a breech-bolt 1' slid mg in the hollowof the breech-frame 2 and receiving the'action of a-recoil spring.
  • the latter is in. the storm ot'a helical spring 3 resting atits-rear end against the bottom of a hollow cap 4 closing the breechframe and at the other end againstthe brim 5 of the socket 6.
  • the latter is put on a cylindrical extent-101i 7 ofzthe breech bolt without being securedto said extension;
  • the breech bolt is yet capable of moving in the breech 1 frame, whilst the extension 7 can slide i reely out 'oitthesocket '6.
  • thesocket 6 is provided with a head" 8 which, when the breech bolt has reached the rear end of its travel, passes through a circular opening provided in the bottomofthe hollow cap 4. Behind said opening is slidably mounted a little arresting or locking member 9, also provided with a circularxopening 12, which canoccupy two positions. a The position sh own in Fig. rem-- responds to the automatic *fire, the head 8 and its.enlarged'portion 11 are then allowed to pass freely through the openings 10 and 12 which-are exactly the one behind the other. Vhenon the contrary themember 9 is in the position shown in Fig. 5, the edge 13 of the opening 12 prevents the enlarged portion 11 from getting out and the recoil spring 3 is consequently locked,
  • the arresting or locking member 9 is displaced by means of the cover 14 secured at the rear end of the cap 4.
  • the inner face of the bottom of this cover is shown in Fig. 7; it is provided with a hollow 15, the edges 18 of which are intended to work as cams and act upon the rounded portion 16 of the arresting member 9 when the cover 14 is caused to turn on the cap 4:.
  • the member 9 is guided during its sliding movements by its rilos 27 which are engaged in corresponding grooves of the bottom of the cap 4.
  • a little spring 17 urges always the arresting member 9 towards the position of semi-air tomatic fire when such a movement is rendered possible according to the position of the cam 18 (Figs. 5 and 6).
  • a button 20 associated with spring 17 and passingthrough the slit 21 ofthe cover is used in order to lock the cover in the one or the other position; this button is provided with a lateral projection 22 which enters into the notches 23 and 24: of the slit 21.
  • the edge of ,the opening 12 is provided with an inclined or bevelled surface 25 in such a manner that if the arresting member 9 is brought into the position for the semi-automatic fire when the breech is closed, at the following recoil movement of the breech bolt the portion 11 of the head 8 urges the arresting member 9 sidewards so aS to enter into theopening 12, after which it is seized by the edge ofsaid opening that comes again in its former position under the action of the spring 7.
  • the recoil spring When the recoil spring is compressed for the semi-automatic fire, it can serve as a buffer in order to damp the impact of" the
  • the cap is secured to the breech frame by any suitable means, such as a bayonetdevice.
  • a breech frame a breech bolt, a socket embracing the rear end of said breech bolt, a helical spring embracing said socket and resting against the rear end of said breech frame, a movable cover at the rear of said breech frame, and means actuated by said cover adapted to arrest and lock the socket to the frame when the spring is compressed so that the bolt may operate independently of said spring.
  • a breech frame In a fire arm, a breech frame, a breech bolt, a socket embracing the rear end of said breech bolt, a helical spring embracing said socket and resting against the rear end of said breech frame, an angularly displaceable cover at the rear of the breech frame, and means actuated by said cover adapted to arrest and'lock the socket to the frame when the spring is compressed, so that the bolt may operate independently of said spring.
  • a breech frame Ina fire arm, a breech frame, a breech bolt, a socket embracing the rear end of said breech bolt, a. helical spring embracing said socket and resting against the rear end of said breech frame, a locking member for said socket, and ,a movable cover arranged at the rear of the breech frame and provided with inner cam surfaces adapted to engage the said locking member so as to move the same into position for arresting and locking the socket when the spring is compressed.
  • a fire arm In a fire arm, a. breech frame, a breech bolt, a socket embracing the rear end of said. breech bolt, a helical spring embracing said socket and resting against the'rear end of said breech frame, a locking member having a bevelled. portion which permits of the spring and socket being automatically locked by the recoil, and a movable cover arranged at the rear of the breech frame and provided with inner cam surfaces adapted to engage the said locking member so as to move the same into position for arresting and locking the socket when the spring is compressed.
  • a breech frame a sliding breech bolt, a socket embracing the rear end of said breech bolt, a helical recoil spring embracing said socket and resting against the rear end of said breech frame, a sliding locking member for the socket, a movable cover arranged at the rear end of the breech frame and provided with inner cam'surfaces adapted to move the locking member into position to lock the socket, and a spring button for locking said movable'cover in any adjusted position.
