Definitions

  • the technical field of the present invention is that of the means for fixing a mouth brake on the tube of a medium or large caliber firearm.
  • patent FR-A-2 718 839 describes a brake of mouth completely surrounding the free end of the tube of the weapon.
  • This mouth brake is attached to the tube by a thread, a lock nut to fix their respective axial position.
  • a key fixed by screw ensures rotational locking of the muzzle brake relative to the tube.
  • Patents CH-A-240 479 and FR-A-715 769 describe a muzzle brake screwed onto the front end of the tube of a weapon. This brake extends the tube and takes support on the front of the tube. No way of stopping is described in these documents.
  • EP-723731 discloses a fixed mouth brake at the front part of a gun barrel by means of a thread.
  • the brake has two cylindrical spans arranged on both sides of the thread and it is held in place with a counter nut.
  • a keyway makes it possible to immobilize an angularly compared to the brake.
  • US-4545285 discloses a reverse brake for small arms. There is no question in this cylindrical guidewrap document arranged in before threading. There is no more question of pressure cooperating with a flat to ensure immobilization in rotation of the brake.
  • the object of the present invention is to provide a device for fixing a muzzle brake on the tube of a weapon to reduce the number of elements ensuring this attachment.
  • the invention therefore relates to a device for attaching a muzzle brake to the tube of a weapon by means of a threaded connection, the muzzle brake comprising a bearing wall cooperating with the front face of the tube, the latter having a cylindrical front bearing disposed in front of the thread and cooperating with a corresponding bearing of the brake ensuring the centering of the brake, characterized in that it comprises at least one means for stopping in rotation the brake interposed between the mouth brake and the tube, stop means constituted by at least one pressure screw disposed transversely between the muzzle brake and the tube and resting on a flat surface formed in the thickness of the tube.
  • the tube comprises a range rear cooperating with a corresponding range of the brake, this rear scope being located opposite the scope before compared to the thread.
  • the stop means is located at a centering point.
  • the screw of pressure has a rotational stop means which can be a locknut.
  • the pressure screw and the flat are positioned so that its clamping prestressed the threaded connection by generating a couple of additional tightening of the muzzle brake on the tube.
  • the axis of the screw of pressure is parallel to a tube diameter and perpendicular to the flat.
  • the axis of the screw of pressure is located at a distance D from the axis of the tube of the order of 0.3 to 0.7 times the outer radius of this tube.
  • two pressure screws are arranged symmetrically with respect to the axis of the tube.
  • the device for attaching a muzzle brake includes a shim arranged between the front face of the tube and the wall of the mouth brake.
  • the advantage of the device for fixing a brake of mouth according to the invention lies in its simplicity which reduces its overall mass.
  • FIG. 1 shows a device for fixing 1 according to 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 typically blades 6 for the passage of gases combustion of the propellant charge.
  • the end 4 of tube 10 comprises a front bearing 7 cylindrical and a 9.
  • the front face 10 of the tube is substantially perpendicular to the axis 2.
  • the muzzle brake 5 has an elongate tubular portion 11 for engage around the end 4 of the tube. This part 11 has a tapping 13 cooperating with the threading 9 and a front reach 14 cooperating with the range 7 of the tube to ensure centering.
  • the brake comprises also a transverse inner wall 15 for come into contact with the front face 10 of the tube.
  • the vanes 6 of the muzzle brake 5 are oriented such that the flue gases from the charge propulsion of a munition are evacuated laterally, in a horizontal plane relative to the tube mounted on tear.
  • the departure Thread thread 9 of the tube is oriented relative to a machining position of the tube on the weapon (no shown), for example a bent keyway the breech sleeve and the tube, and the net start tapping 13 of the muzzle brake is oriented by report to the blades 6.
  • Threads 9 and 13 are shown under a trapezoidal form called artillery but one could apply any other type of threading.
  • FIG. 2 a section is shown transverse tube 3 practiced at the level of means stopping the mouth brake in rotation with respect to tube.
  • These means which are located at the level of the staves 7 and 14 are constituted by two screws 16 se screwing in a thread 17 made in the brake and coming to rest on a flat 18 arranged on the outer part of the tube 3 and perpendicular to the axis 25 tapping.
  • Each screw 16 is stopped in rotation, for example, by a lock nut 19 which is housed in a countersink 27.
  • the positioning of these screws 16 is realized according to the direction of the thread of the threads 9 and 13, so that the tightening of the screws prestressed the threaded connection by generating a couple additional tightening 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 tube, a tightening of the screws tends to turn the brake mouth in a clockwise direction that corresponds to a right thread.
  • the axis of the screws is located at a distance D of the axis 28.
  • the distance D is 0.3 to 0.7 times the outer radius 24 of the tube 3.
  • tapping 17 of the brake and the flat 18 in the thickness of the tube are machined in such a way that they find themselves facing each other when the muzzle brake is in the locking position on the barrel of the weapon.
  • the tapping 17 and the flat 18 are oriented respectively with respect to the vanes 6 of the brake of mouth and the machining of tube positioning on tear.
  • the mounting of the brake is done in the way next.
  • the brake is engaged around the end free of the tube 3 and screw the brake until contact intimate between the front face 10 of the tube and the wall 15.
  • the respective bearing surfaces 7 and 14 of the tube and the brake come into contact.
  • the orientation of departures nets ensures the correct positioning of the brake mouth and its blades 6, as well as threads 17 and flats 18.
  • the screws 16 which ensure a tightening and prestressing torque tapping 13 on the thread 9, then we block the 19.
  • the screws 16 thus obstruct unscrewing the mouth brake.
  • FIG. 3 a variant of the device for fixing a muzzle brake 5 on the tube 3 of a weapon.
  • a second centering of the muzzle brake on the tube is provided.
  • the tube has a second cooperating range 8 with a range 12 of the muzzle brake, these being located behind the threaded connection 9, 13.
  • the assembly of the mouth brake 5 by interposing a shim 20 between the front face 10 of the tube 3 and the wall 15 of the brake of mouth 5.
  • This hold may be in the form a slice of varying thickness, adjusted to the request when mounting the muzzle brake.
  • the net starts are not oriented relative to any reference, which simplifies the machining of thread 9 and tapping 13.
  • the mounting of the muzzle brake is carried out following way.
  • the blades 6 of the muzzle brake are misdirected.
  • the means stopping the mouth brake in rotation with respect to tube can be located indifferently at the level of front centering bearings 7, 14 or rear 8,12.
  • the fixing device according to the invention ensures very easy disassembly of the brake mouth of the weapon tube.
