Definitions

  • This invention relates to improvements in rifles and particularly to a device for preventing that deviation of the shots caused by the influence of the support.
  • the marks show considerable differences when the rifle rests in its front part either upon a support or when it is pressed sideways against a support or when the ring .is carried' out free-handed.
  • the rifle When the rifle is supported in its front part all the shots are above the mark by a definite amount as compared with the results obtained in free-hand shooting, although, when ring, the 'foresightis for instance put below the object in exactly the same manner in both cases.
  • the deviation of the shots in the vertical direction varies with the point in which the rifle is supported, i. e., the nea-rer said point is to themuzzle of the barrel the more the shots are above the mark. In the same way a lateral deviation of the shots occurs when the rifle is in its front part pressed against a side support for the purpose of steadying it.
  • This deviation is caused by the intluence of the support on the barrel of the rifle, and it can be explained in many ways, for instance by a displacement of the nodal points of the oscillations caused by the pressure of the explosion gases or by the influence on the elastic line of the bent barrel caused by the reaction pressure acting at the point of support.
  • the object of the present invention is to eliminate the influences ofthe support and to avoid the faults 'in the r'marks cause-d by said influences.
  • means are provided whereby the barrel is protected from a point near the back-sight to the muzzle, so that when the forward end of the rifle is rested on a support for firing, the barrel shall not be subjected to pressure in al radial direction to the barrel.
  • a sleeve consisting'of a metal tube which is rigidly' connected at its rear end to v.the barrel, the'inside diameter of said tube being larger than the outside diameter of the barrel.
  • Thejtube is conveniently fixed to the vthickened yrear portion of the barrel.l In thiscase it is a'dvantageous tofusea tube of a uniform vinside diameter whereas the barrelistapered towards its muzzle in 'the known manner, so that the annular intermediate space be tween tube andV barrel increases towards the muzzle.
  • Fig. 1 is a side view of a riie
  • Fig. 2 is a longitudinal section through a barrel provided with the device according to the invention.
  • Fig. 3 is a cross-section along line III- III of Fig. 2.
  • a tube 10 (Figs. 2 and 3) is provided which surrounds the barrel concentrically and through which the latter projects freely.
  • This tube 10 is rigidly screwed at 11 to the thickened rear end of the barrel near the point at which the sleeve 12 carrying the back sight is fixed to the barrel.
  • screw threads are provided for screwin the tube 10 thereto.
  • the bore of the tube is uniform throughout its length.
  • the barrel is tapered towards its muzzle in a known manner so that the radial dista-nce 13 or clearance between the tube l and the barrel l increases towards the muzzle.
  • the shell of the tube may be thickened at the portion which is provided with the thread and the tube may further be provided with ribs not shown extending in the longitudinal direction.
  • the barrel together with the tube may be arranged within the hand-guard and the stock (Fig. l) which supports the tubeilO.
  • the metal tube itselt1 may act as and replace the hand-guard, and it can be provided with slots in a similar manner to the cover tube of a mahine gun.
  • the: stock will only extend as far as the dotted line indicated in Fig. l.
  • the hand-guard and the part of the stock may be made of wood and form a tube which surrounds the barrel with radial play. But in this case these parts must be sufficiently rigid ⁇ and their connection to the barrel must I be so rigid as to prevent a bending of these parts from being transmitted to the barrel.
  • a rie comprising a barrel, a protecting sleeve spaced from and surrounding the barrel and secured thereto at its rear end and forming with the latter an annular intermediate free space extending substantially the length of the barrel, whereby when the rifle is supported, for firing, the barrel will not be subjected to a radial pressure, a sight on the barrel in front of the sleeve, and a sight located adjacent the rear end of the latter.
  • a rifle comprising a barrel, a metal tube spaced from and surrounding the barrel and secured thereto at its rear end and forming with the barrel an annular intermediate free space extending substantially the length of thebarrel, whereby when the rifle is supported Jfor iring, the barrel will not be subjected to a radial pressure, a sight on the barrel in front of the tube, and a sight located adjacent the rear end oit the barrel.
  • a rifle comprising a barrel tapered towards its muzzle and having a thickened rear portion, a metal tube spaced from and Vsurrounding the barrel and having a uniform diameter throughout its length and fixed to the thickened rear portion of the barrel, said barrel and tube forming an annular intermediate free space extending substantially the length of the barrel, whereby when the rifle is supported for firing, the barrel will not be subjected to a radial pressure, a sight on the barrel in front ot' the tube, and a sight located adjacent the rear end of the latter.
