Definitions

  • the present invention relates to gun installations to be mounted on vehicles (aircrafts, ships or land vehicles), the expression gun installation including in the present case all arms intended to launch a projectile or a missile either self-propelled or not, that is to say cannons, torpedo launching tubes, rocket launching devices, etc.
  • My invention is more especially but not exclusively concerned with gun installations to be mounted on ships and including guns of relatively small caliber (i. e. from 20 to 50 mm. caliber) intended to fire on targets located substantially at the level of water.
  • the object of my invention is to provide a gun installation which is better adapted to meet the requirements of practice and in particular which facilitates the task of the gunner who is pointing the gun.
  • My invention is concerned with gun installations of this kind including the gun proper, freely pivotable on the vehicle about two axes at right angles to each other, and fixed with respect to said vehicle, and laying control means fixed on a rigid structure carried by said gun so as to have the same rotational displacements with respect to said vehicle as said gun.
  • said rigid structure is freely pivotable with respect to the gun about an axis parallel to the line of fire thereof, but is fixed angularly with respect to said gun about any axis making an angle with said line of fire, and the sighting device of the installation is mounted in fixed position on said rigid structure.
  • Fig. 1 is a perspective view of a gun installation including an automatic gun and intended to be mounted on board a ship, this installation being made according to my invention.
  • Fig. 2 shows the same installation, seen from behind, when the ship is inclined transversely with respect to the line of fire.
  • Fig. 3 is a view similar to Fig. 2 but in which the automatic gun is supposed to have been replaced by torpedo launching tubes.
  • the installation according to my invention includes at least one launching firearm which will be supposed, in the case of Figs. 1 and 2, to be an automatic gun I of small caliber, this gun being mounted freely pivotable with respect to ship N about two axes at right angles to each other and therefore forming a Cardan mount, whereby the gun can be laid both in direction and in elevation.
  • a fixed support 2 rigid with the ship carries a pivoting part 3 rotatable about an axis XX with respect to said support, this axis XX being preferably substantially vertical when the ship is in normal position.
  • Pivoting part 3 carries a pair of trunnions 4 extending Patented Nov. 26, 1957 along the axis YY about which gun 1 can be laid in elevation.
  • the gun proper that is to say the gun barrel and its breech system, is mounted slidable in a cradle 5 pivoted about said trunnions 4, the line of fire of the gun (i. e. the axis of symmetry of barrel 1) being at right angles to the axis YY of trunnions 4.
  • Such a gun installation includes a laying device which is also mounted in Cardan-like fashion with respect to ship N.
  • the axes about which said laying device is pivotable are coincident with pivot axes XX and YY.
  • the gun installation is of the type in which laying is performed directly by the gunner who gives thereto the desired displacements with respect to support 2.
  • the laying device includes a rigid framework 6 which includes shoulder pieces 7 and handles 8 one of which advantageously carries the firing trigger 8a.
  • the gun installation is made as follows:
  • the framework 6 of the laying device is mounted pivotable with respect to the gun cradle 5 about an axis Z-Z fixed with respect thereto and parallel to the line of fire.
  • Said framework has no other degree of freedom with respect to said gun than the possibility thus given to said framework 6 of pivoting with respect to said gun cradle 5 about axis ZZ'.
  • the sighting device is mounted in fixed position on this framework 6.
  • said sighting device includes cross hairs 9 and eyehole 9a.
  • the optical axis of said sighting device i. e.
  • the axis passing through eyehole 9a and the centre of cross hairs 9) may be kept constantly parallel to the line of fire, that is to say to the axis of the barrel 1 of the gun, but it may be made adjustable with respect to said line of fire by providing means for modifying the elevation angle between said optical axis and the line of fire according to the firing conditions.
  • the arrangement is substantially the same when the installation includes, instead of a gun 1, one or several torpedo launching tubes 10, as shown by Fig. 3.
  • these tubes are supported by a frame 11 mounted on support 3 in the same manner as the cradle 5 of the installation of Figs. 1 and 2.
  • the laying device 6 is then pivoted with respect to said frame 11, about an axis ZZ' parallel to the line of fire of the torpedo launching tubes 10.
  • a gun installation which comprises, in combination, a gun freely pivotable with respect to said vehicle about two axes fixed with respect to said vehicle and at right angles to each other, a rigid structure freely pivotable with respect to said gun about an axis parallel to the line of fire thereof, said rigid structure being fixed angularly with respect to said gun about any axis making an angle with said line of fire, laying control means rigidly carried by said structure for displacement thereof by 4 the gunner to enable him directly and instantaneously to turn said structure in any desired direction within given limits with respect to said vehicle, and a sighting device mounted in fixed position on said structure.
  • a gun installation which comprises, in combination, a gun cradle freely pivotable with respect to said vehicle about two axes fixed with respect to said vehicle and at right angles to each other, a gun barrel slidable longitudinally in said cradle, a rigid structure freely pivotable with respect to said gun cradle about an axis parallel to the line of fire of said gun, said rigid structure having a, single degree of freedom with respect to said gun cradle, said degree of freedom consisting in the possibility for said structure of rotating about said last mentioned axis with respect to said gun cradle, laying control means rigidly carried by said structure for displacement thereof by the gunner to enable him directly and instantaneously to turn said structure in any desired direction within given limits with respect to said vehicle, and a sighting device mounted in fixed position on said structure.
