Definitions

  • the invention relates to a fire arm having a muzzle brake screwed to the forward end of the barrel of the weapon and secured against detaching, whose fixing por- ⁇ tion is constructed in the shape of a sleeve with a frontal slotted safety crown.
  • the muzzle brake In a weapon of this kind the muzzle brake is secured against turning loose by a leaf spring, which is attached on the barrel and engages into a slot of a slotted crown.
  • the muzzle brake is connected with the barrel in such a manner that when tightening the screw thread, a shoulder in the bore of its sleeve-shaped fixing portion is pressed against the frontal end face of the barrel of the weapon.
  • the muzzle brake has to be firmly clamped to the barrel since experience has shown that with a muzzle brake loosely mounted thereon the hitting accuracy of the shots fired through the same is diminished.
  • the disadvantage of the manner of securing the muzzle brake hitherto used consists in that the muzzle brake must accurately match the barrel on which it is to be fitted in order that the leaf spring can catch.
  • the invention has the primary object of obviating this disadvantage and of providing an attachment of a muzzle brake to the barrel of a fire arm which is secured against unintentional loosening and which allows exchangeability of the matching components without requiring any touching up or adaptation work.
  • a fire arm comprising in combination: a barrel, a muzzle brake in screw-threaded connection with the forward end of said barrel and having a frontally slotted sleeve-shaped safety attachment portion, an external truncated cone pointing forward being provided on said barrel and a complementary internal truncated cone being provided at the rear end of said slotted sleeve-shaped portion, said internal truncated cone having longitudinal slots spreading on said external truncated cone when screwing fast said muzzle brake on said barrel.
  • FIG. 1 is a side elevation of the forward end of the barrel of a weapon with muzzle brake
  • FIG. 2 is a section on line II-II of FIG. l.
  • the muzzle piece 1 is provided with sleeve-shaped attachment portion 2, which is screwed on the thread 14 at the forward end of the barrel 3 of the weapon and is centred thereon by means of two cylindrical bore surfaces 4 and 5.
  • sleeve-shaped attachment portion 2 which is screwed on the thread 14 at the forward end of the barrel 3 of the weapon and is centred thereon by means of two cylindrical bore surfaces 4 and 5.
  • six slots 8 are machined at equal angular distances parallel'to theV external conical surface 11 converging towards its centering surface 10 whose aperture angle corresponds to that of the complementary conical surfaces of the fingers '7a.
  • a groove 12 is machined parallel to the axis thereof whose forward end lies ahead of the conical surface 11.
  • a leaf spring 13 is fixed, whose length and width corresponds to that of the slots 8 of the muzzle brake 1 and whose forward end is turned up so far that its protrudes from the groove 12 but can yet be resiliently pressed completely into the groove.
  • the muzzle brake can be fixed to the barrel 3 of the weapon as follows:
  • the ngers 7a, external cone 11 and complementary cone 9 are to be dimensioned so that the stressing of the lingers 7a remains within the elastic limit of the material, even when the spreading on the external cone 11 takes place upon turning the muzzle brake about its longitudinal axis to an extent corresponding to the full angular distances of two successive slots 8.
  • muzzle brakes can be used without any touching up or adaptation work, the adaptation of the actually existing dimensional relations of the barrel of the weapon and of the muzzle brake being effected by a more or less large elastic deformation of the fingers of the slotted safety crown.
  • a fire arm comprising in combination a barrel having at the front end thereof an exterior thread and an exterior cone shaped portion, the apex of Y said portion pointing towards the front, a slot in the exterior surface of said barrel extending parallel to the longitudinal axis of said barrel adjacent the front end thereof, a muzzle piece having an interior thread to be screwed on said exterior thread and an interior cone shaped portion complementary to said exterior cone shaped portion, said piece having at its rear end regularly spaced longitudinal slots forming fingers, said interior cone shaped portion being arranged on said fingers, a spring tongue fixed at one end in said slot of said barrel and with its free end designed for engaging in one of said slots, said spring being capable of being disengaged from said slots radially and resiliently by depression of said free end, whereby the expansion of said fingers by said exterior cone shaped portion permits a rotation of said muzzle piece relative to said spring tongue.
  • a fire arm comprising in combination a barrel having at the front end thereof an exterior thread and an exterior cone shaped portion, the apex of said portion pointing towards the front, a slot in the exterior surface of said barrel extending parallel to the longitudinal axis of said barrel adjacent the front end thereof, a muzzle piece having an interior thread to be screwed on said exterior thread and an interior cone shaped portion complementary to said exterior cone shaped portion, said piece having at its rear end a sleeve with regularly spaced References Cited by the Examiner FOREIGN PATENTS 279,063 10/ 30 Italy 42-79 BENJAMIN A.
