Definitions

  • the present invention relates to a device for re arms whereby the sounds, flames and recoil will be prevented or diminished.
  • the throttling means will perform only a secondary and supplementary function, and in many cases may be entirely eliminated, and I employ an essential principle ofquite another nature, disposing for this purpose at the end of the gun barrel a metal casing or box pierced with an aperture for the passage of the projectile, and the said aperture is automatically closed, or reduced in section, as soon as the projectile has been discharged. In this manner the major part of the gas is retained in the interior of the apparatus, and it can only be evacuated through special orifices.
  • FIG. 1 is a diagrammatic view showing an embodiment of the invention.
  • Figs. 2 to 6 are-'modified forms of construction.
  • the apparatus comprises a metal box or casing A, preferably of cylindrical shape, which is mounted on the end of the gun barrel C; the diameter of the aperture a is larger than that of the barrel; so as to afford passage to the projectile without friction.
  • a second box B of tapered shape At the exterior of the box A is placed a second box B of tapered shape; which is pierced with the aperture b.
  • the said outer box is mounted on the inner box in such manner that it'will pivot about the axis c.
  • the aperture a of' the inner box coincides with the aperture b so as to allow free passage for the projectile. I/Vhen the shot has been fired, the gas lssuing from the barrel and partially expanded in the box A, w1ll pass through the aperture mand will thus raise the box B by pivotation on the axis o to a stated point at which it is held by suita le means. At the same time the aperture b moves upwardly and the aperture a is closed by the wall of the box B.
  • the projectile has time to traverse the apparatus before it is closed, but the major part of the gas is now enclosed and can only escape in a slow and noiseless manner through the interstices between the two boxes or through special apertures.
  • the apparatus To continue the firing, the apparatus must be brought into the open position at each shot, and to this effect the apparatus is automatically opened by means of a spring, or positive control may be employed, and chiefly in the case in which the apparatus is mounted upon a machine gun and herein the device for closing the said outer or damping part is connected with one of the movable parts of the machine gun.
  • F or instance-and 'solely b way of examplevalves e may consist of7 balls contained in the apertures m in the Wall of the barrel portion which form valve seats, said balls c being held inv place by a separate envelope d fitting upon the barrel portion A and pierced withA orifices e for the gas circulation.
  • Vsecond closing 1s effected by the motion of the outer box relatively to the stationary b'ox A mounted on the n barrel 4.-, so that the exit aperture b will e displaced from the axis of the barrel.
  • the said shutter f has a very li ht construction and forms a closing device oi cylindrical outline which is movable along a corresponding surface formed on the end wall closing the barrel portion Awhich is pierced with the said aperture for the exit of the projectile.
  • the shutter f is provided with two lateral arms g which are pivoted at h upon the barrel portion A, so that the device may leave a clear path for the projectile.
  • the arms g are controlled by the respective push rods or tappets v1 which are suitably guided, said tappets are connected together b a cross-piece j making contact with an elastic abutment lc which is mounted on the movable outer box B.
  • the shutter f When in the inoperative position (Fig. 3). the shutter f will close the end of a conduit Z which extends along the interior of the barrel part A and whose rear end is adjacent the end of the gun barrel oifering passage to the projectile.
  • the'box B takes the position shown in Fig. 5 in which it closes the aperture d of the barrel ortion A; by its motion, the box B has acte upon the tappets z' by means of the abutment lc, and the said tappets havebrought the shutter f into the o en position.
  • I claim- 1 In a gun silencer, the combination of bers mounted on the end of the gun barrel, the inner chamber being relativel iiXed and the outer chamber being relative y movable, vsaid"'chambers being provided with openings which normally register in alignment with the gun barrel to provide a projectile outlet, whereby movement of the outer chamber will destroy said registry to obturate said outlet.
  • a pair of nesting chambers mounted on the end of the gun barrel, the 81 inner chamber being fixed to the gun barrel and the outer chamber being pivotally mounted with respect to said fixed chamber, said chambers being provided with openings which! the gun barrel to provide a projectile outlet, whereby pivotal movement of the outer chamber will destroy said registry to obturate said outlet.
  • a pair of nesting cham- 9' bers mounted on the end of the gun barrel, the inner chamber being fixed to the gun barrel and the outer chamber being pivoted at its rear end to said inner chamber, the front walls ⁇ of said chambers being provided with 1 openings which normally register in alignment with the gun barrel to provide aprojectile outlet, whereby pivoting of the outer chamber about its rear end will destroy said registry to obturate said outlet.
  • a pair of nesting chambers mounted on the end of the gun bar ⁇ rel, the inner chamber being relatively fixed and the outer chamber beingrelativelypivotable, the forward walls of said chambers be- 1 ing cylindrical and slidably superposed whereby ivoting of the outer chamber will callllse sai walls to slide relatively to each ot er.
  • a pair of nesting cham- 1 bers mounted on the end of the gun barrel, the inner chamber being relatively fixed and the outer chamber being relatively pivotable, the forward walls of said chambers being cylindrical and slidably superposed whereby 1 pivoting ofthe outer chamber will cause said walls to slide relatively to each other, and said forward walls being provided with openings which normally register in alignment with the gun barrel to provide a projectile outlet 1 which is obturated when said relative sliding occurs.
