Definitions

  • rifle grenades anti-tank, anti-personnel, smoke grenades, and so on
  • these grenades are generally fired with the aid of a detachable throwing sleeve provided with an aiming sight which, for the purposes of giving the same a universal character, has been provided with a series of different markings which frequently lead to confusion in reading the sight and increase the risks of error.
  • the sighting device arrangement of the present invention aims at obviating these disadvantages.
  • the sighting device consists of a detachable sight provided with means which are adapted to secure said sight to the projectile before firing and to enable it to be detached therefrom after the shot has been fired, the dimensions of said sighting device being such that it can be housed in the fincarrying tail of the grenade.
  • Figure l is a fragmentary longitudinal section of the tail of a grenade containing a propulsive cartridge and the sighting device;
  • Figure 2 is a side view of the sighting device fitted on the fin assembly of a grenade
  • Figure 3 is an elevation of the same.
  • the arrangement illustrated is adapted to enable the rifleman to aim by aligning the target over a straight line tangential to the largest-diameter zone of the body of the grenade and passing through the elevation level corresponding to the distance required.
  • the sighting device comprises a small bar 1, preferably of a transparent synthetic material, having a series of steps or levels 2 cut out from said bar and graduated according to the ranges to be reached.
  • This bar can of course be made of any other suitable material and may have painted or engraved levels.
  • the bar 1 On its front face the bar 1 is provided with a clip 3 adapted to clip on to the rear part of one of the fins 4 of a fin assembly made of synthetic resin and disposed at the end of the tail 5 of a rifle grenade.
  • the clip comprises two spring strips adapted to hold the sight on the fin assembly of the grenade, the diametric positioning of tates Patent 0 F Patented Jan. 24, 1961 the said sight with respect to the longitudinal axis of the grenade being determined by the stop 6 bearing on the outer edge of the supporting fin, disposed perpendicularly to the plane of the horizon.
  • the sighting device can be housed in the tail 5 of the grenade, which is closed by a plug 7 provided with the propulsive cartridge 8 ( Figure 1).
  • the rifieman On firing, the rifieman has to remove the plug 7 in order to place the grenade on the throwing sleeve, then removes the sighting device from its housing, in which it is perfectly protected, the sighting device corresponding exactly to the type of grenade he is preparing to launch. Any risk of error is therefore eliminated.
  • the latter Due to the spring clip on the sighting device, the latter is thrown ofi from the projectile after the shot has been fired, under the combined effects of the positive acceleration and of the air resistance, and drops a few feet away from the rifleman.
  • the method of fixing the sight on the grenade has been illustrated solely by way of example. If the fin assembly contains an annular part enclosing the fins, the sighting device can be fastened there in the same manner as on a radial fin.
  • the invention is applicable to grenades fired by means of any firearm whatsoever, such as a pistol, and so on.
  • a sighting device for a rifle grenade and the like having a recessed tail and fin assembly comprising a sighting member having length and diameter less than the recess of the grenade tail in which it is stored, said member having means for temporarily securing the said sight member to one of the fins of the grenade fin assembly before launching and capable of separation from the said sight member from the grenade after the shot has been fired.
  • a sighting device for a rifle grenade and the like having a recessed tail and fin assembly comprising a sighting member having length and diameter less than the recess of the grenade tail in which it is stored and a clip integral with the front face of the said sight member, for temporary attachment to the fin assembly and separable from the grenade after the shot has been fired.
