Definitions

  • the present invention relates to means for preventing or at least partly absorbing injurious reboundings of systems which are to be stopped, at least temporarily, by abutment against a fixed element.
  • the invention is more especially, although not exclusively, concerned, among these means, with those intended to prevent dangerous rebounding of parts or combinations of parts adapted to keep temporarily in active position a system for ensuring the locking of the breech system of an automatic firearm.
  • the object of the present invention is to provide means of the type above mentioned which are better adapted to' meet the requirements of practice than those used for the same purpose up to the present time.
  • I provide, in the system which is to be protected against rebounding, at least one chamber or recess in which is mounted a sliding mass adapted to undergo, under the effect of inertia and against the action of an elastic device, when the system is stopped by abutment, a displacement at the end of which there is produced a shock against the front end of its chamber, said mass being preferably chosen in such manner that its momentum substantially balances the rebounding energy of the system when the shock in question takes place.
  • Fig. 1 is an elevational view of the breech mechanism of an automatic gun made according to the present invention, with a device for preventing the rebounding of certain parts;
  • Fig. 2 is a transverse sectional view on the line IIII of Fig. 1;
  • Fig. 3 is a horizontal sectional view on the line III-III of Fig. 1;
  • Fig. 4 is an elevational view similar to Fig. 1, showing the breech mechanism in the locked position.
  • the object of the invention is to provide a device for preventing the detrimental rebounding of the parts which temporarily maintain the breech system locked in active position.
  • the firearm is devised in such manner that, when the breech system is locked, a rigid whole, including a firing pin or the like and safety inclined surfaces, keeps moving toward,
  • the safety tion (that is to say the rigid whole above mentioned including the safety inclined surfaces in the case of theautomatic firearm above considered) at least one chamber or recess, L in which is mounted a sliding mass M adapted to undergo, by inertia and against the action of elastic means S, as soon as said whole comes to abut, at the end of its stroke, against a fixed part of the arm, a displacement producing a shock against the front end of chamber L.
  • mass M comes to produce, against the front end of its chamber, a shock in the course of which it imparts to said assembly its own momentum which is in a direction opposed to the rebounding force of the firing pin assembly.
  • the relative masses of said system and of element M will be chosen in such manner that the momentum of said element, when the shock takes place, substantially balances the perturbing rebounding energy.
  • This breech box 2 includes the following elements:
  • an aperture 4 which may be diametrally opposed to said slot, for the outlet of the empty shells of the spent cartridges.
  • I provide, for reciprocating movement in said box 2, a breech block 6.
  • the breech block 6 carries a firing pin as- .be fired by the firing pin ll.
  • a spring 5, eating on the firing pin assembly urge the breech block 6 toward its closing position in which the breech block has pushed the cartridge into the gun chamber and into position for firing.
  • I provide means, such for instance as the combination of a'cylinder l2 and a piston IS, the movable part of which is rigid with a push piece I4, for ensuring, owing to the pressure supplied by a portion of the burnt gases, the recoil movement of slide members 9 until the rear edges 9" thereof cease to act on” the locking means 'I and said slide members come to abut against breech block 6 which is then disengaged from, breech box 2, owing to the reversibility of inclined surface IS on which the locking means I is bearing, said breech block being then pushed rearwardly together with the slide members 9 to which it is then secured through the locking means I.
  • I provide respectively in each of the slide members 9 two chambers or recesses L in which are mounted masses M the sliding displacements of which are guided by pistons 31 aeerass whichengage in holes provided for this purpose in said masses.
  • Springs S are provided on the inside of said holes so as to urge the masses rearwardly '(toward the positions of rest illustrated by Figs. 1 and 3).
  • safety springs I! also oppose, to a certain degree, a. detrimental rebounding of the slide members, but their action is purely of a static nature, and they serve rather to prevent any undesirable backward movement of said slide members under the action of gravity for instance when the gun is vertical, or in case of breaking of the return spring.
  • an automatic fire arm including a. breech box and a breech block slidabiy mounted in said breech box for movement to and fromfiring position, a firing pin assembly carried by said breech block normally to move therewith, said firing pin assembly including a pair of slide members disposed on the sides of the breech block, said breech block having a transverse opening and said slide members being connected by a transverse bar disposed through said opening, the opening being of greater width than the width of said bar, whereby the firing pin assembly may move forwardly a slight distance to fire a cartridge after the breech block has engaged the cartridge in firing position, a spring acting against the firing pin assembly for urging said assembly and the breech block forwardly, temporary locking means for locking said slide members and said breech block together when the latter is not in its full forward position and for locking the breech block with respect to the breech box when the breech block is in full forward position, said locking means being actuated to its'last named locking position by continued forward movement of said slide members
