Definitions

  • This invention relates to gun firing and has for its object to provide means by which the flame and flash that accompany the projectile on its flying past the gun muzzle can betotally suppressed.
  • This flame is very objectionable, specially at night, as it allows the enemy to discover where the gun is located, and correct his aim for the destruction of the Gun, however well the latter may be conceale f
  • this 2 being the smoke that is produced even when using the so called smokeless powder, a fact that has not been reasonably explained so far, but that appears' due to the relatively long time the projectile remains in the barrel, which allows a portion of the powder charge not to be ully burned and to reach the muzz le of the gun in a smoky condition but not hot enough to burn either on coming into Contact with atmospheric air.
  • This eec't that has been proved by real experience. is attained by primarily placing inside the barrel, between the top of the charge and the bottom of the shell, a certain quantity of a cooling substance, either fluid or finely divided solid matter and arranging besides at the niuzzle end of the gun a device that automatically injects a supplement-ary portion of the finely divided cooling means into the still burning gases before their flight into the air behind the shell.
  • Figure 1 is an axial sectional view of the portion of a gun where the shell and charge are placed when loading the gun:
  • Figure 2 is an axial sectional View of the muzzle arrangement according to one forni of the invention, of which Figure 3 is a crossv section on the line a--a;
  • Figure 4 is a viewsimilar to Figure 2 of a rather modified form of the muzzle arrangement
  • Figures 5, 6, 7 and 8 being a sectional axial view, a cross sectional View, a front and perspective View respectively of one of the flame diverging means adopted with this arrangement and Figures 9, 10, 1?. are radial and cross sectional views respectively of one or more internally baffle plated rings as are fixed inside and on the outer end of the muzzle member, in order to still deviate the remnants of the gases, and cooperate to check the recoil of the gun, and the noise of the shot.
  • Figure 12 is in an axial sectional View of a further modified form of the muzzle arrangement, in which a portion of the .gases are deflected rearwardly;
  • Figure 13 being a perspective View of another gas defiecting means, in connection with this invention.
  • Figure 14 is an axial view of a still further modified form of the device according to this invention specially adapted for small bore guns and machine guns.
  • Fig. 15 is an enlarged fragmentary sectional View corresponding to a portion of Fig. 14 but showing one of the valves in detail.
  • Fig. 16 is a transverse section on the line iG-ic of Fig. i5.
  • this invention aims primarily to cause that portion of the calories produced by the ignition of the owder charge, which are not utilized for the propulsion of the shell or projectile to be ab- Accordingly a first soibcd and destroyed.
  • cooling der means will intimately mingle with the gases, partly following the shell, partly expanding sideways in the direction shown by arrows 7 into the expansion chamber 15, the admixture of such cooling means with the gases already causing the latter to be greatly cooled down.
  • This object has been attained by a rolongation added to the gun muzzle, an so construct this added member as to force the gases to deviate from the course of the shell and to cause another quantity of cooling material to be sent into the mass of said gases, just behind the projectile.
  • the device comprises a cylindrical hollow member 10 having its axis coincident with the gun axis, and constituted as a sleeve throughy which the shell can freely pass during its flight.
  • This sleeve 10 is fixed onthe outside of the gun, near its muzzle, in any convenient manner, as for instance by screwing asl at 8 and 9.
  • the sleeve 11 has one or more cucularly arranged series of perforations 12, and the diaphragm 11 has' one or more flanged openings 17 which' permlt communication of chamber A14 with any convenient container of the cooling meansnot v represented, from which by any convenient means whatever as by compression said coolmg means may be fed.
  • Freely mounted on the inner sleeve 11 are two iston-like metal rings 18, 19, which may sli e tightly in the chamber 14, forming between them a circularV74 chamber v17 which is filled up with the cooling means as fed through-the holes 17', the
  • the cooling means will thoroughly be pulverized and vaporized as well as intimately mixed with the gases which will have followed the shell in its flight and even afterward with the other portion of gasesrwhich has concurred to set the system of piston-like rings in operation. In this way, the energy of these gases will fully be absorbed and no suflicient quantity of them will still remain to produce the undesirable llame.
  • the outside sleeve or jacket according to this modified form is screwed on to the gun as at 8 with a flanged portion 21 against ther muzzle face of the gun where it can be fixed in any convenient manner.
  • the inside sleeve 11 is made with a restricted mouth at its rear portion 27 widening therefrom, said sleeve 2o bein supported by an additional sleeve 23,
  • a i5 large expansion chamber 15 for the powder gases is formed in the jacket where the gases flow as shown by arrows 7: said-chamber 15 being closed forward by a piston-like ring slidably mounted on the sleeve 11, to form 20 the chamber 17 which communicates as in the former construction with the refrigerating means supply container not shown, through a hole 17 As in the former construction the perforations 12 are supplied to permit of the cooling means being injected into the sleeve as in the former case.
  • a number of shell like tubes 27 having preferably a square cross section and a curved shape as shown in detail in axial and cross sectional views in Figures 5 and 6 and in front and prospective views in Figures 7 and 8 respectively.
  • rings 30 inside and near the outer opening of member 23 are one or more rings 30, as shown in detail in Figures 9, l0 and 11, in their axial sectional and front 3 views respectively. These rings have inside fixed small baille blades 31 of any convenient shape, set at an inclined position with respect to the axis of the gun.
  • the modified form of construction of the llame reducing in guns as specified with reference to Figure 4 is particularly useful with long barreled guns, in which, as stated above, beside the llame the projectile is accompanied in its flight by a certain amount of smoke, which will be widely suppressed due particularly to the restriction 22 of tube 11 as well as to the intimate mixture of the cooling matter and the inflamed gas which is obtained by the deviation of the gases in a direction normal to the gun axis caused by tubes 27.
  • a portion of the gases immediately after their flying past the gun muzzle is deflected backward and either dispersed into the atmosphere behind the gun or by means 305 of an artificial physical or chemical cooling process, caused to be thoroughly absorbed and anyhow rendered harmless to mens health.
  • v Referring to Figure 12, according to this modified form of device, conveniently fixed on the muzzle end is a kind of hollow metal cap 40 so sha ed, as to facilitate the gas flowing backwar through tubes 43, 44 fixed on a convenient prolongation of jacket 10, as shown by the arrows 50.
  • a cap 45 Freely slidable in the jacket 10, but with a good contact with the jacket wall in order to prevent gas escape, is a cap 45, the backward movement of which is limited in a convenient manner, as by an annular stop 46.
  • the jacket 10 is shut by a front cover 47, having a central hole in which a tubular prolongation 49 of the cap, can slide as in a guideway. In this way the usual chamber 17 1s provided between the cap and the jacket cover, into which cooling matter may be sent through a spring controlled valve 48 and feeding tube 17.
  • the cap 45 is supplied with perforations 12 as in the preceding cases, through which the cooling means may be ejected when, owing to the forward impulse of the powder gases, the cap is moved forward, saiilcap being sent back when the pressure inside it 1s extinguished, by the pressure ofthe incoming cooling means.
  • Batlle rings 30 may be provided atthe jacket mouth as in the preceding case, and besides some baflling members 101 of pressed metal as shown in Figure 14,1nay be provided in order to more fully deviate the powder gases before escaping behind the projectile, and also to stand a part ot the impulse oi said gases, in the opposite direction to the. recoil of the gun, which latter will be consequently diminished.
  • FIG. l-'l shows a still further modified form ⁇ ot the arrangement according to this invention, particularly ⁇ adapted for small bore guns, rifles, machine gunsand the like.
  • a hole (il is drilled in the wall of the gun, in correspondence with the charge chamber B. on which a bent tube G2 is conveniently fixed, which widens in a chamber (S3 where a piston (ist may tightlyv slide, forming and limiting a further chamber G3 communicating through a tulze 17 with a cooling matter feeding container not shown.
  • a tube G5 that runs parallel to the gun barrel near the muzzle of which it is fixed as at (3G, where another hole communicates again with the barrel.
  • a hindering valve as 'diagrammatically shown in Figure 15 such valve having a rod G8 being guided in a plate 6T and controlled by a spring G9 so that the cooling matter, either mixed to the powder gases or not. cannot pass forward or backward unless acted upon by the pressure of the powder gases, when the valve plunger will be acted upon and moved forward against tht ⁇ action of the .spring and permit the passage of the gases and cooling matter which will be injected into the barrel in the, proximity of the muzzle, said gases being efiicientlv cooled ⁇ down and the flame disappearing.
