Definitions

  • the present invention concerns certain improvements in automatic fire-arms and relates more particularly to improvements in the mechanism permitting the stoppage c of the fire-arm after the cartridges contained therein have been used up.
  • the tray is subas block and a rapid deformation ensues therefrom, either in the tray or in the loading case, which roduces defective pro ession of the cartridges through the loa er and risks of j ammingowing to the cartridge being defectively presented before the block;
  • the sear in the second case, the sear must be actuated by a.comparatively weak spring so as not v tohinder the descent of the cartridges and, in consequence, its arresting action is only more or less eflicacious, besides, a scar of this kind can only be'used in' connectionwith loaders in-which the cartridges are arranged in a single line and not in quincunx.
  • the object of the present invention is to remedy these defects and the mechanism to which it applies, not only stops the firearm after the cartridges have been used up,
  • the mechanism according tion is essentially characterized by the com-- bination of a checkin sear capable of engaging in a correspon in recess of the fire arms breech block in or er to arrest it, and of an oscillator hinged to the loading tray arm of which, after the cartridges have been used up, takes the place of the last cartridge fired, and is then acted on by a the ejected, the,
  • the upper arm causes the sear to engage with the breech block, means being provided for holding the loader in place during fire. and for automatically ejecting, it after the cartridges have been placement of the slide withou a corresponding, displacement of the sear.
  • inven tion inorder to permit the upper arm of the oscillator, which ishinged to the end of --the loading tray and is located within the loader, to act on.t he displaceable slide which is located outside the loader, a port of suitable shape is made in'the wall of'the-loaderfacing said upper arm and said slide and through which the said arm canpass.
  • the meansenabling'the loaderto be kept in place during tion of its spring, into its forward position in which it. holds said shoulder in place.
  • the front part of the slide is suitably profiled so that, on the loader being placed in position, the aforesaid-shoulder may itself displace said slide (corresponding to the play provided between the slide and the push button) which, as soon as the shoulder takes up its normal position, will returnfunder the ac-
  • the forward movement of said slide is checked by a fixed or adjustable stop.
  • these means are provided for enabling the loader to be. removed even though it still contains cartridges, these means com 1- prising, for example, a pivoting lever having ,a nose which, by cooperating with a tail carried by the slide, shifts said slide longitudinally to a suflicient extent to free it from the shoulder.
  • ig. 1 shows the fire-arm in firing position, cartridges being contained in the loading case.
  • Fig. 1 shows the position of the various parts 'of the mechanism according to the invention after the cartridge supply has been exhausted.
  • Fig. 2 shows the same mechanism at the instant when the breech block has come into contact with the oscillator.
  • Fig. 3 shows the same mechanism the leader has been ejected.
  • This breech block performs a reciprocating-motion and is drivto the invention is supposed to be app ied to an automatic fire-arm en, from rear to front, by its return spring and, from front to rear, by the gas pressure resulting from the explosion of the cartridge fired off.
  • the fire-arm A is fed with cartridges by means of a loading case 1 through the breach block B which pushes them into the barrel and fires them off.
  • an oscillator 6 is hinged at 5 to the rear end of the loading tray 4, said oscillator having an upper arm 8 and a lower arm 7 which, after the cartridges2, have been completely used up, and as may be seen in particular in Fig. 2, can take up the position of the final cartridge fire, i. e. the position in which it is in the path of the breech block B.
  • the upper arm -8of the oscillator 6 is located facing a port '9 made in the rear wall of "the loader 1, which enables this arm 8 to come into contact with the end of a slide 10, on
  • a certain amount of play as seen 'at 18, is pro vided between the head of the push button 11 and the slide 10, so as to allow thisslide to be displaced eventually without a corresponding pivot movement of the sear 13 taking place.
  • This latter hasmoreover a toe 19 the front end of which ma be actuated by the lower edge of a shoul cf 20 carried externally by the rear wall of the loader 1, slightly below the. port 9.
  • This shoulder 20 may be held in place at its upper end by the slide 10 itself. as seen in Fig.1, and the breadth of this shoulder is such that when the slide 10 is displaced. through a distance 1 equal to the play 18'which exists between said slide and the push button 11, this slide 10 is completely disengaged from the shoulder 20'so as to free this latter.
  • the relative position of the recess 16 md of'the usual stop notch 21 of the block B is such that when this block is maintained in the full cocked position by the sear O 4 (as shown in Fig. 1), the nose 15 is slightly to the rear of the recess 16, and, conversely, when the breech block B is kept stationary by the nose 15 (as shown in Fig. 3), this block has still a slight distance to traverse,
  • the loader is mounted in the following manner: The front part is first of all mounted in the usual manner as at 5. It is then swivelled round 5. The shoulder 20 then comes into contact with the slide 10 the profile of the corre sponding end of which is such that this shoulder 20 automatically thrusts back the slide 10, i. e. shifts it longitudinally through a distance equal to the play 18. The loader can then be lowered completely and brought into the position shown in Fig. 1. As soon as it attains this position, under the action of the spring 17, the slide 10 returns into its forward position in which it bears against the upper part of the shoulder 20. As moreover this shoulder abuts at its lower part against the toe 19 of the sear 13 the loader is firmly held in position. It will be noticed that the shoulder 20 can be mounted whatever the position of the sear 13 may be.
  • thebreech block B reclprocates and, at each forward stroke, causes a cartridge 2 to be introduced into the fire-arm and exploded.
  • the above described mechanism is then idle.
  • the loading tray 4 comes into the position shown in Fig. 1 in which the arm of the oscillator 6 occupies the position of the final'cartridge fired.
  • the breech block B enters on its for-- ward stroke, it acts on the arm '7 and-causes the oscillator 6 to pivot, the arm 8 of which thereby causes the slide 10 to be shifted'longitudinally towards the rear (Fig. 2).
  • the spring 17 may be of considerable strength without the descending movement of the cartridge being hindered thereby.
  • the spring 17 acts on the slide 10 the forward movement of which, that is to say the sole movement which might 'interferewith the movement of the cartridges, is checked by the stop 26.
  • the comparatively great strength of this spring 17 will enable it, on acting on the arm 12 of the sear 13 through the medium of the push button 11, to cause the nose 15 to sink rapidly and, in consequence, to effect a definite stoppage of the breech block B.
  • these means comprise a lever 22 pivoting about a fixed pin 23 and'having a nose 24 which, when the lever 22 is brought into the position'shown in dotted lines in Fig. 1, acts on a toe 25 in one piece with the slide 10.
  • This device might be replaced by an ordinary hook in one piece with the toe 25 and directly controllable by hand.
