Definitions

  • the present invention relates to a shotgun with juxtaposed barrels, the convergent tubes of which are integral with a hoop the base of which is articulated on the rocker rigidly mounted on the butt of the rifle.
  • an object of the present invention is to produce a shotgun with juxtaposed barrels, which would allow the use of cannons of several calibers while requiring only the production of a single scale and also a single hoop for these calibers.
  • the distance between the levers of the rocker is identical for all sizes and has a value of 26.5 mm, i.e. the center distance corresponding to size 16.
  • the convergence of the barrel tubes is identical for all the calibers and has the value 0 ° 27 ', namely the convergence corresponding to caliber 16 .
  • fig.1 which shows a perspective view of part of a hunting rifle, there is shown the butt 1 carrying a block 2 forming a rocker, and provided with a lower extension 3 on which is articulated, by all suitable known means, not shown, a part 4 forming the lower cover of the rifle and on which the two tubes 5 of the juxtaposed barrels rest.
  • These tubes 5 are made reciprocally integral by a hoop designated by the reference 6 and which envelops them at least partially at their lower part and which extends over a limited length at this rear end of the barrel tubes, said tubes being by elsewhere joined together, in other suitable locations, by known means such as bands not shown, and this between them as well as at the lower cover 4 of the rifle.
  • fig.2 which is a plan view of the assembly of fig.1, we see that the axes 7, 8 of the barrel tubes converge towards each other symmetrically by relative to the axis 9 of all the barrels, in the direction of the outlet mouth of said barrels.
  • the distance between the strikers at the level of the lever was 29.5 mm and 26.5 mm respectively for calibers 12 and 16 respectively, while the distance between the front ends of the barrel (end on the right in the figure) was 21.33 and 20.92 mm respectively for the sizes considered.
  • the idea underlying the invention consists in adapting to the same rifle, that is to say for the same rocker 2, barrels 5 of different calibers.
  • the rifle's rocker is made so that the distance between the strikers is equal to 26.5 mm, that is to say a unified value corresponding to the caliber 16. Similarly the distance at the end of the barrels is chosen equal to 20.92 mm corresponding to this same caliber.
  • the hoop the axial length of which is preferably 61.5 mm, is identical for the two calibers considered from the point of view of its internal structure. In addition, it is dimensioned from the point of view of its external contour so as to accommodate the barrel tubes corresponding to caliber 16.
  • the outer contour designated by the reference 10 corresponds to the gauge 12 while the inner contour of the hoop, designated by the reference 11, relates to the gauge 16.
