Definitions

  • the invention relates to a firearm with at least two barrels superimposed with adjustable geometry, which are interconnected by at least one band.
  • the gap between the point of impact of a bullet fired by one of the cannons and the point of impact of a bullet fired by the other cannon must be limited. Standards of acceptance are such that at a determined distance of target, this gap must be practically nonexistent.
  • the guns are linked together by a band so that the guns are converging.
  • One of guns is in this case cleared at the front of the weapon of this above strip and is moved away from the strip, and therefore from the other barrel, by means of a ring which surrounds the cleared barrel and which is retained in place on the barrel released by a muzzle which is removably mounted on the other gun.
  • the invention aims to avoid the above drawbacks and to procure a weapon with at least two cannons which allows relatively precise, easy and quick adjustment of the cannon geometry and whose construction is very simple and aesthetically justified.
  • a firearm with at least two superimposed cannons linked together by a strip except over a length from the mouth of barrels, the front parts of the barrels being convergent if they are not dismissed under duress, this weapon being characterized in that the strip is fixed to the barrel lower almost to his mouth but is clear of the upper barrel over a distance from this muzzle, the upper barrel being surrounded at the front by a ring spreading it by elastic deformation of the band and so from the lower barrel and the ring is retained in place by the handlebar base which is fixed on the end of the upper barrel.
  • the invention also includes a method for adjusting the barrel geometry in front of a two barrel weapon superimposed and connected by at least one strip which, at the front is released from the upper barrel.
  • Figure 1 a gun, more particularly a rifle, with two superimposed barrels 1 and 2 which are connected by a central strip 3 and which are brazed in a hoop not shown.
  • the strip 3 is brazed, for example with silver, over its entire length at lower barrel 1, practically up to mouth of this canon 1 for example up to a few millimeters from that mouth.
  • This strip 3 is, on the other hand, only soldered on part of its length at the upper barrel 2, and is released on a distance, for example about a third of its length, to from the muzzle of the upper barrel 2, by a clearance 4 as shown in FIG. 2.
  • the clearance 4 is provided on a certain length of a deeper part 5.
  • Cannons 1 and 2 are, where they are connected by the strip 3, slightly converging and the cradles or areas of contact of strip 3 with guns 1 and 2 form a small angle A between them.
  • the outer and inner surfaces of the ring 6 are concentric and the inner diameter of the ring 6 corresponds to the outside diameter of the upper barrel 2.
  • This ring 6 is part of a series of rings having different outside diameters.
  • the ring 6 shown in Figures 1 to 4 is the smallest ring in the series.
  • FIG. 5 is a section similar to that of FIG. 4, but with ring 6 having an outer diameter more tall.
  • cleat 7 which is brazed on the barrel 2 and which is provided with a threaded hole 8 and a hole 9.
  • a handlebar base 10 which is fitted with a removable handlebar 11.
  • a transverse groove 12 is machined in the base 13 of handlebar base 10.
  • the width of the groove 12 corresponds to the width of the ring 6 and the depth of the groove 12 is greater than the thickness of the largest of the 6 rings in the series aforesaid.
  • the upper part of the ring 6 is housed in this groove 12.
  • the handlebar base 10 is positioned on the barrel upper 2 using a pin 14 which is housed, a hand, in a passage 15 which is below the handlebars removable 11 and which is produced in a handlebar base 10, and on the other hand, in the hole 9 of the cleat 7.
  • the handlebar base 10 is fixed to the barrel 2 by means a fixing screw 16 which passes through an opening 17 in the handlebar base 10 and which is screwed into the threaded hole 8 of cleat 7.
  • one of the rings 6, normally the most small, is slid onto the upper barrel 2 and is immobilized in place by means of the handlebar base 10 which retains the ring 6 axially in place by the fact that the ring 6 is housed in groove 12.
  • Shots are fired by the two cannons 1 and 2 on a target at a specified distance.
  • the gap between impacts is checked and if this is not acceptable, the ring 6 the above is replaced by another ring 6 with a larger diameter tall.
  • the rifle user cannot disrupt the geometry of barrels 1 and 2.
  • the setting is not disturbed by dismantling the rifle. If the handlebar base 10 and the ring 6 are removed, their replacement ensures automatically the perfect setting.
  • the setting depends on effect only of the outer diameter of the ring 6 and of its axial position on the barrel 2.
  • handlebars 11 need not necessarily be removable and can be an integral part of the base handlebar 10.
  • fixing screw 16 of the base of handlebar 10 can be screwed directly into the barrel upper 2 without cleat 7 intermediate, provided of course that the wall of the barrel 2 is sufficiently thick.
  • the correct positioning of the handlebar base 10 on the barrel 2 can be achieved for example by a shape of the base 10 which is perfectly adapted to the shape of the barrel 2 and / or the shape of the cleat 7.
  • the handlebar base 10 can of course consist of several pieces which yes or no are fixed separately on the upper barrel 2 and of which one or more parts retain the ring 6 axially in place on the barrel 2.
  • the invention is not limited to rifles, but is also applicable to other weapons with two or even more than two cannons.
