Definitions

  • the fire-arm includes a breech casing, a barrel recoiling with respect to the breech casing against elastic return means and a rigid support on which the breech casing slides.
  • the elastic damping device interposed between the breech casing and the rigid support is an elastic cylindrical sleeve inserted between the two axial stop surfaces.
  • the cylindrical sleeve has two elastic end zones separated by a rigid zone.
  • the rigid support has two cylindrical co-axial rings axially separated. Yokes are used as removable fixing means for a cylindrical collar to the rigid zone.
  • the weapon can be a fixed or movable installation.
  • the present invention relates to fire-arms including a breech casing with respect to which the barrel of the fire-arm is mounted to recoil against the action of elastic return means, the breech casing being mounted on a rigid support itself belonging to a firing installation which may be fixed (casemate) or movable (terrestrial, maritime or aerial vehicle), this firing installation including generally a turret enabling the fire-arm assembly to be oriented.
  • the invention relates more particularly, because it is in this case that its application seems to have most advantage, but not exclusively, among such fire-arms, to automatic or semi-automatic fire-arms of a caliber comprised between and 50 mm.
  • the fire-arm according to the invention includes a breech casing, a barrel recoiling with respect to said breech casing against the action of elastic return means, the breech casing being mounted slidably on a rigid support with the interposition of an elastic damping device between said breech casing and said rigid support, and is characterized by the fact that,
  • the breech casing of the fire-arm has a cylindrical collar for sliding and guiding
  • the rigid support includes two co-axial cylindrical rings and separated axially from one another, the inner diameter of these cylindrical rings and their axial separation being such that said cylindrical collar occurs constantly engaged, on firing, in said cylindrical rings which ensures permanent guidance of the breech casing of the firingarm,
  • the elastic damping device is constituted by a cylindrical sleeve inserted between two axial stop surfaces occurring opposite and belonging respectively to the two cylindrical rings, this cylindrical sleeve including two elastic end zones (preferably with identical mechanical characteristics) separated by an intermediate rigid zone, removable fixing means (preferably yokes) being provided to fix at least axially the cylindrical collar of the breech casing of the fire-ann with the intermediate rigid zone of the said cylindrical sleeve.
  • the cylindrical sleeve is constituted by a section of metal having elastic characteristics and including an intermediate solid zone (constituting the intermediate rigid zone) and two end zones cut along circular sectors arranged in staggered arrangement (constituting respectively the two elastic end zones).
  • the two ends of the cylindrical sleeve include means of assembly holding the end considered in contact with the surface of the corresponding axial stop, so that each elastic end zone of the said sleeve works, on firing, under compression and under traction, the abovesaid assembly means being also capable of immobilizing in rotation the above-said cylindrical sleeve with respect to the cylindrical rings of the rigid support.
  • FIG. 1 is a diagrammatic view in perspective of a first embodiment of a fire'arm according to the invention
  • FIG. 2 is a partial view in elevation of the embodiment of FIG. 1;
  • FIGS. 4 and 5 lastly, illustrate respectively, by partial axial sections, two further embodiments of a fire-arm according to the invention.
  • the fire-arm includes a breech casing 1 with respect to which the barrel T of the fire-arm is mounted to recoil against the action of elastic return means R.
  • the breech casing 1 is mounted on a rigid support 2 belonging to a firing installation (casemate, terrestrial, maritime, aerial vehicle, etc.).
  • This firing installation includes generally a turret enabling the whole of the fire-arm to be oriented.
  • An elastic damping device is interposed between the breech casing 1 and the rigid support 2.
  • the breech casing l of the fire-arm has a cylindrical driving and guiding collar 3
  • the rigid support 2 includes two co-axial cylindrical rings 4 and 5 and separated axially from one another, the inner diameter of the cylindrical rings 4 and 5 and their axial separation being such that the above-said cylindrical collar 3 occurs constantly engaged, on firing, in the abovesaid cylindrical rings 4 and 5 which ensure a permanent guidance of the breech casing l of the fire-arm,
  • the cylindrical sleeve 6 is constituted by a section formed of a metal having elastic characteristics, this section including an intermediate solid zone constituting the rigid intermediate zone 11 and two end zones cut along circular sectors 13 arranged in staggered arrangement, these two out out end zones constituting respectively the two springs or elastic end zones 9 and 10.
  • These assembly means 14 and 15 may advantageously be of the dovetailed type.
  • removable fixing means 12 may also fix in rotation the cylindrical collar 3 of the breach casing 1 of the fire-arm with the intermediate rigid zone 11 of the cylindrical sleeve 6.
  • Such means of rotary immobilization may advantageously be constituted by dovetails which constitute the assembly means 14 and 15 due to which the elastic end zones 9 and 10 of the cylindrical sleeve 6 work under compression and under traction on firing.
  • yoke form fixing means 12 may be of various types, but it would seem that preference should be given to yoke form fixing means 12 comprising two parallel yokes l8 and 19 held respectively in two parallel grooves 20 and 21 fashioned in the cylindrical collar 3 of the breech casing 1 of the fire-arm and in two parallel housings 22 and 23 arranged in the intermediate rigid zone 11 of the cylindrical sleeve 6.
  • a fire-arm in which the elastic damping device interposed between the breech casing of the fire-arm and the rigid support is simple, light, robust, easily interchangeable and lends itself to rapid dismounting and remounting of the assembly constituted by the breech casing and the barrel with respect to its rigid support.
  • this elastic device has a small bulk, which constitutes an important advantage in certain firing installations.
  • Fire-arm especially an automatic or semi-automatic firearm of a caliber comprised between 20 and 50 mm, including a breech casing, a barrel recoiling with respect to said breech casing against the action of elastic return means, the breech casing being mounted slidably on a rigid support with the interposition of an elastic damping device between said breech casing and said rigid support,
  • the breech casing having a sliding and guiding cylindrical collar
  • the rigid support including two cylindrical and co-axial rings axially separated from one another, the inner diameter of said cylindrical rings and their axial separation being such that said cylindrical collar is constantly engaged, on firing, in said cylindrical rings which ensure permanent guidance of the breech casing,
  • the elastic damping device being constituted by a cylindrical sleeve inserted between two axial stop surfaces facing and belonging respectively to the two elastic end zones separated by a rigid zone, removable fixing means being provided to fix the cylindrical collar at least axially to said rigid zone,
  • each end of the cylindrical sleeve includes means for assembling and holding the end concerned in contact with the surface of the axial stop, so that each elastic end zone works, on firing, under compression and under traction.
  • cylindrical sleeve is constituted by a section of metal having elastic properties and including a solid intermediate zone constituting said rigid zone, and two end zones cut along circular sectors in staggered arrangement, constituting respectively the two end elastic zones.
