Description

       

  La présente demande de brevet se rapporte à des perfectionnements

  
 <EMI ID=1.1> 

  
arme à feu comportant notamment un mécanisme d'arme dans lequel un bras mobile portant une saillie pénétrant dans une encoche de la culasse, peut être déplacé alternativement pour mettre le percuteur sous-pension, ledit bras mobile pouvant être abaissé par un levier pour permettre le tir dit

  
 <EMI ID=2.1> 

  
Le but de l'invention est de prévoir un perfectionnement qui écarte tout risque de voir l'arme s'enrayer lors du tir dit "à répétition". 

  
A cet effet un levier de blocage, soumis à l'antagonisme d'un res-

  
 <EMI ID=3.1> 

  
le bras mobile n'a pas ramené la culasse dans sa position la plus avancée du côté du canon de l'armée

  
Selon une forme de réalisation avantageuse, le levier de blocage susdit pénètre par un ergot dans une rainure du premier levier, un tenon monté sur le bras mobile et guidé dans ladite rainure venant en contact avec ledit ergot pour extraire celui-ci hors de la rainure précitée. 

L'invention a également trait à la culasse de l'arme à feu.

  
D'autres détails et particularités ressortiront d'ailleurs de la description qui sera donnée ci-après à titre d'exemple nullement limitatif et avec référence aux dessins ci-annexés, Les notations de référence se rapportent aux figures ci-annexées  La figure 1 montre en coupe-élévation le mécanisme d'arme, la culasse et le percuteur étant disposés vers l'avant, La figure 2 montre en coupe-élévation le.même mécanisme d'arme, la culasse et le percuteur étant disposés vers l'arrière. La figure 3 montre, en élévation, les deux parties de la culasse <EMI ID=4.1>  La figure 4 est une vue, de profil des deux parties de la culasse de l'arme suivant l'invention,.

  
L'arme à feu illustrée par ces figures comporte un canon 1, une boîte-culasse 2 et un bras mobile 3 destiné à assurer l'arme,, En effet, ce bras mobile 3 présente une saillie 4 qui pénètre dans une encohe 5 de

  
 <EMI ID=5.1> 

  
bras mobile 3 est rappelé en arrière (vers la gauche selon les figures 1 et 2) les deux parties de la culasse se déplacent donc dans le même sens,

  
 <EMI ID=6.1> 

  
Le ressort 7 traverse une pièce fendue en forme de fourche 10, le ressort 7 prenant appui à l'arrière sur les épaulements intérieurs d'un 

  
 <EMI ID=7.1> 

  
guidage 12 etc un ressort de rappel 13, lequel peut être comprimé entre la pièce 11 et la partie avancée d'une fente 14 prévue longitudinalement dans la partie de culasse 60

  
Le fonctionnement du mécanisme d'arme est identique à celui qui a été décrit en détail au brevet principal. En plus est prévu un levier de blo-

  
 <EMI ID=8.1> 

  
d'un ressort de rappel 17, peut pénétrer par son ergot 18 dans la rainure 19 du levier 20 De cette façon, lorsque le levier 20 est en position horizontale, ce qui correspond, au tir à répétition, on ne doit pas craindre que l'arme puisse s'enrayer par suite d'un affaissement léger du levief 20, au moment ou le tenon 21 vient s'engager dans la rainure 19..Pendant le moment

  
 <EMI ID=9.1> 

  
tant par rapport à la culasse qu'au levier déterminant le tir automatique ou à répétition. 

  
 <EMI ID=10.1> 

  
cution qui vient d'être décrite et que bien des modifications pourraient y être apportées ? notamment à la disposition, au nombre et à la conformation des éléments intervenant dans sa réalisation sans sortir du cadre de la présente demande de brevet.

  The present patent application relates to improvements

  
 <EMI ID = 1.1>

  
firearm comprising in particular a weapon mechanism in which a movable arm carrying a projection penetrating into a notch of the breech, can be moved alternately to put the firing pin under board, said movable arm being able to be lowered by a lever to allow the shot says

  
 <EMI ID = 2.1>

  
The aim of the invention is to provide an improvement which eliminates any risk of seeing the weapon jamming during so-called “repeated” firing.

  
For this purpose a locking lever, subjected to the antagonism of a res-

  
 <EMI ID = 3.1>

  
the movable arm did not return the breech to its most forward position on the army barrel side

  
According to an advantageous embodiment, the aforesaid locking lever penetrates through a lug into a groove of the first lever, a tenon mounted on the movable arm and guided in said groove coming into contact with said lug to extract the latter from the groove above.

The invention also relates to the breech of the firearm.

  
Other details and particularities will moreover emerge from the description which will be given below by way of non-limiting example and with reference to the appended drawings. The reference notations relate to the appended figures. FIG. 1 shows in sectional elevation the weapon mechanism, the breech and the firing pin being disposed towards the front, FIG. 2 shows in sectional elevation the same weapon mechanism, the breech and the firing pin being disposed towards the rear. FIG. 3 shows, in elevation, the two parts of the breech <EMI ID = 4.1> FIG. 4 is a side view of the two parts of the breech of the weapon according to the invention.

  
The firearm illustrated by these figures comprises a barrel 1, a breech box 2 and a movable arm 3 intended to secure the weapon ,, In fact, this movable arm 3 has a projection 4 which penetrates into a notch 5 of

  
 <EMI ID = 5.1>

  
movable arm 3 is returned to the rear (to the left according to Figures 1 and 2) the two parts of the cylinder head therefore move in the same direction,

  
 <EMI ID = 6.1>

  
The spring 7 passes through a split part in the form of a fork 10, the spring 7 bearing at the rear on the inner shoulders of a

  
 <EMI ID = 7.1>

  
guide 12 etc a return spring 13, which can be compressed between the part 11 and the advanced part of a slot 14 provided longitudinally in the cylinder head part 60

  
The operation of the weapon mechanism is identical to that which has been described in detail in the main patent. In addition, a locking lever is provided.

  
 <EMI ID = 8.1>

  
of a return spring 17, can penetrate through its lug 18 into the groove 19 of the lever 20 In this way, when the lever 20 is in a horizontal position, which corresponds, to repeated firing, one should not fear that the 'weapon can jam as a result of a slight sag of the levief 20, when the tenon 21 comes to engage in the groove 19. During the moment

  
 <EMI ID = 9.1>

  
both in relation to the breech and the lever determining automatic or repeated firing.

  
 <EMI ID = 10.1>

  
cution which has just been described and that many modifications could be made to it? in particular the arrangement, number and conformation of the elements involved in its production without departing from the scope of the present patent application.
