Definitions

  • This invention pertains to weapons and the ballistics thereof, and in particular to means for effecting random dispersion of bullets from a gun barrel, as well as to a blank for forming therefrom means for effecting random dispersion of bullets from a gun barrel.
  • means 10 for effecting random dispersion of bullets from a gun barrel comprising a sleeve 12 of cylindrical conformation with three vibratory reeds or fingers 14, 16 and 18 projecting from an end of the sleeve 12.
  • the embodiment here depicted is formed of spring steel.
  • the body 20 portion of the means 10 is of cylindrical conformation, as noted, but the reeds of fingers 14, 16 and 18 are flat.
  • the fingers or reeds 14, 16 and 18 are of diverse lengths. Consequently, each thereof will respond differently to pressure.
  • the gases exiting with the rounds will insinuate themselves between the rounds and the fingers or reeds.
  • the proximity of the rounds to the fingers or reeds causes the intervening gases to be pressured and, resultantly, the fingers or reeds are set into vibration.
  • the vibration of the fingers or reeds further pressure the gases, cyclically (as each round exits), and different ones of the rounds, therefore, are randomly slightly displaced in their exiting paths.
  • the gases will not build up in the gun barrel, and, consequently, each singled round will target with all the accuracy built into the weapon. It is in the firing off of bursts of rounds where the gases accumulate and vie with the rounds in exiting the muzzle, and cause the gas pressure excursions to manifest themselves at sides of the different rounds where the fingers or reeds 14, 16 and 18 are located.
  • FIGs 4 and 4a through 11 and 11a more graphically depict the functioning of the invention in connection with an alternate embodiment 10a of the novel means.
  • the reeds 14a, 16a, 18a, 18b are of common length. Due to imprecision in manufacture, however, and due to vagaries in metallic structure in each reed, the four will not vibrate in common under the same circumstances, each will have its own distinct harmonic. By chance, then, as illustrated in Figures 4 and 4a through 6 and 6a, some one or more rounds in a burst -- or a singled off round -- will cause no dispersion thereof.
  • means 10a is shown with an end thereof clinched about a gun barrel 22 which has an annular groove 24 formed therein in which to latch the end of the body 20a.
  • the body 20a could be internally threaded, and the outer surface of the barrel 22 threaded to receive it. Too, the body 20a could carry a sort of pipe clamp thereabout to facilitate its mounting to a muzzle quickly, without undue complication.
  • FIGS 12 through 14 depict a novel blank 26 from which means for causing random dispersion of bullets is made.
  • the blank 26 has straight sides 28 and 30 which are joined to form a cylindrical body 20b.
  • Sides 28 and 30, in the formed bullet disperser are held in abutting relationship by the resilience of the material of the blank; optionally, however, they could be spot welded, or equal.
  • Four limbs 32 extend from one end of the blank 26 and they are collinearly aligned with four reeds 34 formed in the blank by four U-shaped cut-outs 36.
  • the reeds 34 are bent, as shown in Figure 13, to define thereof a knee 38 from which the rest of each reed 34 extends, in cantilever fashion, in parallel with the plane of the blank 26. Too, the limbs 32 are bent back upon themselves, by the "cuffing" back of the ligament 40 -- which is interposed between the limbs 32 and the reeds 34. The turned back or cuffed ligament strengthens the formed disperser.
  • my invention comprises means for damping the vibratory excursions of the reeds 34, and the damping means are provided by the bent back, or turned back limbs 32, as can be seen with particular clarity in Figure 13, the ends of the limbs 32 are bent back to near proximity to the reeds 34. The degree of proximity accommodates that degree of vibration for the reeds. But if the reeds attempt to exceed the optimum amplitude, the limbs 32 inhibit this.
  • the bullet disperser means 10 and/or 10a can be slipped onto the muzzle of a rifle or the like under any combat conditions, in darkness, rain, cold, etc. This can be done with an interference fit, or with a pipe clamp (as suggested), etc. Just as easily, too, it can be removed from the muzzle when it is desired to employ the built-in accuracy of the weapon.
