This invention relates to arms of the rocket launcher type and more particularly to a shield for projector weapons.

One object of the invention is to provide arms of the rocket-projecting type, firing self-propelled projectiles, with suitable means for effectively protecting the face and eyes of the firer from the gases and solid particles ejected by the nozzles when the projectile leaves the barrelof the weapon.

Hitherto it had been proposed to provide the mouth of the rocket projector with a deflector for the purpose of deflecting the jet of gases. Nevertheless, this solution presents some disadvantages. The firer is in fact subjected to the recoil of the weapon, resulting from the action of the gases on the useful section of the deflector. In addition, this type of protection masks a considerable portion of the field of visibility when the firer shoulders his weapon.

A more specific object of the invention aims at obviating the foregoing disadvantages and to this end, provides a shield of generally conical shape, widening out from the front to the rear, at least a part of which shield is transparent, and the axis of which shield coincides with that of a sighting telescope.

In accordance with another feature of the invention, the narrowest part of the shield is placed near and in front of the objective lens of the telescope. In this way the head of the firer, and moreover also the telescope itself, are protected against the gases.

As the shield is fixed on the weapon, in particular by being set back from the mouth of the barrel, it offers practically no resistance to the thrust of the gases and consequently the recoil of the weapon is nil.

A further object of the invention is to provide said shield with a rigid mounting consisting of two pieces solid with one another and between which is fixed the front edge of the shield, which is made of a flexible and elastic material. This assembly is at the same time simple, practical, and rugged, the shield being deformed elastically under the effect of untimely stresses in transport and manipulation.

According to a subsidiary feature of the invention, said mounting comprises a device for fixing the shield to the telescope support, so as to make the shield readily removable. The apex of the shield may advantageously be provided with a glass disc intended to protect the objective lens of the telescope against particles emanating from the nozzles and, during transportation, against sand and dust.

Finally, it is preferable, according to the invention, for the shield to have a transparent lateral window, the remainder of the surface being opaque.

This technical feature provides the advantage that the firer is not inconvenienced during sighting by the exterior light which may be reflected on to the metal parts of the weapon and of the telescope.

Other advantages and features of the inven tion will become apparent from the following description taken in conjunction with the accompanying drawings which illustrate diagrammatically and by way of example one embodiment thereof, and in which:

Figure 1 is a general side view of the projector arm;

Figure 2 is a plan view of the part of the arm 5 with the shield in axial section;

Figure 3 shows a rear end view of the shield through the interior;

Figure 4 is a view of the shield partly broken away.

In accordance with Figure 1, the projector arm I is constituted by a barrel tube open at both ends and equipped with a sighting telescope 2 inslde a shield 3 intended to protect the face of the marksman.

The shield 3 is a sheet of flexible and elastic material, covered with a protective varnish, and has a transparent window 4 permitting the marksman to survey the field of fire.

This flexible sheet is fixed rigidly between the

conical parts

5 and 6 by the tightening of the screw 1. A glass disc 8 is held in a mount 9 and closes the apex of the shield, thus protecting the objective lens of the telescope 2, which rests at its front part in a rubber ring I0 solid with the part 5.

The eyepiece of the telescope 2 is in addition capped by a protective tip ll.

Finally, the shield according to the invention has a U-shaped fixing device l2 which engages with the support I3 of the telescope 2. A spring ing a transparent portion, the apex of said shield being provided with a glass disc, to protect the objective lens of said telescope."
