Definitions

the technical field of the present invention is that of the means for fixing a muzzle brake on the barrel of a medium or large caliber firearm.
patent FR-A-2,718,839 describes a brake mouth completely surrounding the free end of the tube of the weapon.
This muzzle brake is fixed to the tube by a thread, a stop nut for fixing their respective axial position.
a key fixed by screw secures the muzzle brake in rotation relative to the tube.
the object of the present invention is to provide a device for fixing a muzzle brake on the tube a weapon to reduce the number of elements ensuring this fixation.
the invention therefore relates to a device for fixing a muzzle brake on the barrel of a handgun using a threaded connection, the muzzle brake comprising a bearing wall cooperating with the face front of the tube, characterized in that the tube has a cylindrical front bearing disposed in front of the thread cooperating with a corresponding span of the brake ensuring the centering of the brake, and in that it includes at least one brake stop means interposed between the muzzle brake and the tube.
the tube has a rear reach cooperating with a reach corresponding to the brake, this rear range being located opposite the front span relative to the thread.
the stop means is located at a centering span and is consisting of at least one pressure screw arranged transversely between the muzzle brake and the tube.
the screw is supported on a flat formed in the thickness of the tube and has a stop means in rotation can be a lock nut.
the pressure screw and the flat are positioned so that its tightening preloads the threaded connection by generating torque additional clamping of the muzzle brake on the tube.
the axis of the pressure screw is parallel to a diameter of the tube and perpendicular to the flat and is located at a distance D from the axis of the tube of the order of 0.3 to 0.7 times the outside radius of this tube.
two pressure screws are arranged symmetrically with respect to the axis of the tube.
the device muzzle brake attachment has a shim disposed between the front face of the tube and the wall of the muzzle brake.
the advantage of the fixing device of a brake mouth according to the invention lies in its simplicity which reduces its overall mass.
FIG. 1 there is shown a device for attachment 1 along a half-cut made along the axis 2 of the tube 3 of a weapon not shown.
the end 4 of the tube 2 receives a muzzle brake 5 comprising conventionally vanes 6 intended for the passage of gases of propellant charge combustion.
End 4 of tube 10 includes a cylindrical front seat 7 and a thread 9.
the front face 10 of the tube is substantially perpendicular to the axis 2.
the muzzle brake 5 comprises an elongated tubular part 11 intended for engage around the end 4 of the tube. This part 11 includes a thread 13 cooperating with the thread 9 and a front reach 14 cooperating with the reach 7 of the tube to ensure centering.
the brake has also a transverse internal wall 15 intended for come into contact with the front face 10 of the tube.
the blades 6 of the muzzle brake 5 are oriented so that the charge gases from the charge propellant of an ammunition are evacuated laterally, in a horizontal plane with respect to the tube mounted on tear.
the departure of thread of pipe thread 9 is oriented relative machining the tube on the weapon (not shown), for example a keyway binding the cylinder head sleeve and the tube, and the thread start of the muzzle brake thread 13 is oriented by compared to the vanes 6.
Threads 9 and 13 are shown under a so-called trapezoidal artillery form but we could apply any other type of thread.
FIG 2 there is shown a section transverse of the tube 3 practiced at the level of the means muzzle brake rotation stop relative to tube.
These means which are located at the ranges of centering 7 and 14, are constituted by two screws 16 se screwing into a thread 17 made in the brake and coming to rest on a flat 18 arranged on the outer part of tube 3 and perpendicular to the axis 25 of the thread.
Each screw 16 is stopped in rotation, for example, by a lock nut 19 which is housed in a counterbore 27.
the positioning of these screws 16 is made according to the direction of the thread of threads 9 and 13, so that the tightening of the screws preloads the threaded connection by generating torque additional clamping of the muzzle brake on the tube.
the screws 16 are in the sectors angular S and S 'delimited by two diameters perpendiculars 21 and 22 of the tube. Axis 25 and 26 of each of the screws being parallel to a diameter 21 of the tube, tightening the screws tends to turn the brake mouth clockwise which corresponds to a right hand thread.
the axis of the screws is located at a distance D from the axis 28.
the distance D is 0.3 to 0.7 times the outside radius 24 of the tube 3.
the thread 17 of the brake and the flat 18 in the thickness of the tube are machined in such a way that they meet face to face when the muzzle brake is in the locked position on the barrel.
the thread 17 and the flat 18 are oriented respectively with respect to the vanes 6 of the brake mouth and tube positioning machining on tear.
the brake is assembled in the same way next. Apply the brake around the end free from tube 3 and screw the brake until contact intimate between the front face 10 of the tube and the wall 15. As the tightening progresses, the respective ranges 7 and 14 of the tube and the brake come in contact. The orientation of departures from threads ensure the correct positioning of the brake mouth and its blades 6, as well as threads 17 and flats 18. Then tighten the screws 16 which provide a tightening and prestressing torque for the thread 13 on thread 9, then block lock nuts 19. The screws 16 thus obstruct the unscrewing the muzzle brake.
FIG. 3 a variant of the device for fixing a muzzle brake 5 to the tube 3 of a weapon.
a second the muzzle brake is centered on the tube.
the tube has a second bearing 8 cooperating with a range 12 of the muzzle brake, these being located behind the threaded connection 9, 13.
the assembly of the muzzle brake 5 by interposing a shim 20 between the front face 10 of the tube 3 and the wall 15 of the brake mouth 5.
This wedge can be in the form a washer of variable thickness, adjusted to the request when installing the muzzle brake.
the thread starters are not oriented relative to any reference, which simplifies the machining of thread 9 and thread 13.
the muzzle brake is assembled from the next way.
the muzzle brake vanes 6 are incorrectly oriented.
the means muzzle brake rotation stop relative to tube can be located indifferently at the level of centering spans front 7, 14 or rear 8.12.
the fixing device according to the invention ensures very easy disassembly of the brake muzzle of the barrel.
