Definitions

  • the sear acts on the fore body of the inertia mass, i. e. on that gliding on the barrel, allowing thus the functional movements of the weapon to be distributed in a particularly suitable way in respect of the features of the weapon having a small calibre, i. e. easy handling, limited dimensions, absence of projecting parts, etc.
  • Fig. 1 shows an external view of the weapon from the left side, with the bolt closed, without magazine;
  • Fig. 2 shows a partially cross-sectioned external view of the weapon, from the right side
  • Fig. 6 shows the cross-section of the Weapon along the line VIVI of Fig. 3;
  • Fig. 7 shows the cross-section of Fig. 3 along the line VIIVII
  • the main parts of the Weapon are: a cylindrical receiver 1, wherein glides the inertia mass formed by two hollow cylinders 2 and 3 (Fig. 3) connected by strong lateral links 4 (Fig. 2); the barrel 5 ending at its fore extremity with a threaded portion 6 having a minor diameter; a box 7 containing the firing mechanism which may be integral or not with the handle.
  • the receiver 1 is inserted at its front extremity in an annular bushing, which ends the fore part of the box 7, and at its rear it is inserted on the vertical element 9, forming the ejector tooth.
  • the receiver bears: at its fore part the foresight 14, and at the rear a sight 15, roughly in correspondence with the handle 16 of the weapon, an upper opening 17 for the ejector of the empty shell and a corresponding lower opening 18 (Fig. 5) through which the cartridge to be fired is extracted from the magazine.
  • the helical retractor spring 23 encircles the barrel 5 and is inserted between the fore body 2 and the barrel so that said spring is comprised between said fore body and the step limiting the front of the breech ring 19.
  • a stationary firing pin 26 At the centre of the fore surface of the bolt is placed a stationary firing pin 26. At the upper fore part of the cylinder 24 is pivoted the extractor 27, pressed by a spring 59 (Fig. 3).
  • the firing mechanism comprises a trigger 31 pressed by a spring 32 and pivoted on the shaft 33 which passes through the lateral cheeks of the mechanism box and which is fixed on the right cheek as it will be described herebe ow.
  • the scar 37 has in its'upper part a corner edge 41 which may engage with its edge turned toward the handle, the fore end of the cylinder 2 of the inertia mass, in order to block it ready to fire, or in safety with the bolt open, and with its rear surface on an inclined plane 42 of the rear part of cylinder 2, in order to block the inertia mass in safety position with the bolt closed.
  • the scar 37 is pressed by the spring 43 to remain in its lifted position, i. e. in its position of engagement with the cylinder 2.
  • Said positions are defined by small seats provided in the left check of the weapon wherein an internal projection of the flat lever 46 may be engaged, and remain there, by effect of an internal spring 47 (Fig. 5) acting on the fire-control 44, keeping the latter adherent against the right cheek of the weapon.
  • the small cylinder 44 engages the right lever 36 (Fig. 3) keeping it lowered and preventing it from engaging in its turn the tooth 40 of the sear 37.
  • the weapon remains therefore open, and in order to cause the successive shot it is necessary to release the trigger in order to bring back the firing lever and to operate successively the trigger in order to cause the lowering of the sear.
