Definitions

  • an aiming device for use when'the weapon is being used as a grenade thrower comprising a sort of graduated scale extending in general in a plane perpendicular to the axis of firing, the graduations of the said scale enabling the firer to take different lines of sight corresponding to different firing distances.
  • the axis of the barrel defines with each generatrix thereof a half-plane which can appropriately be called a radial half-plane of the barrel"; the radial half-plane corresponding to the upper generatrix of the barrel (in the shouldered position under consideration) is then vertical and will be referred to hereinafter as the upper radial half-plane of the barrel.
  • each kind of firing operation has a fixed aiming plane relatively to the weapon. These two planes intersect along a line above which, for each method of firing (the gun being in the firing position) there extends an upper aiming half-plane.
  • the two upper aiming halfplanes form a dihedral angle which is nil in known weapons of this kind up to the present day.
  • the weapon has necessarily to be supported, for firing grenades, in a position wherein the said radial-half-plane is verticaland orientated upwards.
  • the necessity of adopting a firing position of this kind has the result of situating the aiming scale relatively to the ground at a level which is the maximum level which the said scale can occupy for a given orientation of the barrel of the weapon whose butt; is supported on the ground.
  • the object of the main feature of the invention is to obviate the disadvantages mentioned hereinbefore, that is to say permit the person firing the weapon to fire grenades whilst remaining in a position in which he is more plane of the barrel of the weapon forming a substantial angle, advantageously with the upper radial halfplane of the said barrel and, on the other hand, on the same side as that at which the first-mentionedv radial halfplane extends from the axis of the barrel, and the said scale can advantageously be carried by the grenadethrowing device and, relatively to the said device, can have firstly a degree of angular freedom about a transverse axis such that the scale can be swung over in the position of rest againstthe upper portion of the device, and secondly'a degree of angular freedom about an axis parallel to the axis of the barrel permitting the said scalejto be orientated when in the operative position parallel to a plane forming a substantial angle with the upper radial half-plan
  • FIG. 1 of these drawings illustrates in perspective and in the firing position for throwing grenades, a rifle equipped with a grenade-throwing device, this assembly being arranged in accordance with the invention.
  • FIGS. 2a, 2b and 2c are diagrammatic views intended to show how advantageous the invention is, FIG. 2a showing a conventional grenade-throwing rifle in the firing position whereas FIGS. 2b and 2c show, also in the firing position, grenade-throwing rifles constructed in accordance with two forms of embodiment of the invention.
  • FIG. 3 is a view on a larger scale, in perspective and with parts broken away, of the front end of a grenadethrowing rifle constructed according to the form of embodiment which was the subject of FIG. 2b, the said rifle being provided with a grenade-sleeve equipped with an aiming scale.
  • FIGS. 4 and 5 finally, illustrate the said form of embodiment respectively in axial section and in cross-section taken on V--V of FIG. 4.
  • the said weapon can be constructed in any desired appropriate manner and, more particularly and as illustrated in FIG. 1, by providing the weapon with a barrel 1 sup ported by a stock 2 which itself supports the breech mechanism 3 and the trigger mechanism 4 of the weapon, the said stock continuing rearwardly to merge into a butt 5 whose general shape is flattened and whose median line forms an obtuse angle with the axis of the barrel 1,
  • the grenade-sleeve essentially as a tubular element 6 whose rear portion can fit on the forward end of the barrel 1 whereas its forward portion is adapted to be surrounded by the rear tubular portion of the grenade 7 which is to be thrown.
  • the aiming scale 8 with which the weapon is to be supplemented as stated hereinbefore it is preferably carried in a manner known per se by the sleeve 6 and, advantageously, the said scale 8 is articulated on a swivel pin 9 perpendicular to the axis of the sleeve 6, so that the said scale can be swung over on to the body of the sleeve in the position of rest, the scale in question being illustrated in the operative position in FIG. 1, on the contrary, i.e. in a position in which it extends in a plane which is preferably perpendicular to the axis of the barrel 1 of the weapon.
  • the aiming scale 8 was disposed in the upper radial half-plane P of the barrel 1 of the weapon.
  • FIG. 2a shows a rifle arranged in accordance with this prior art, in a position for firing grenades, the rifle being supported on the ground by the lower point a of its butt 5, so that the aiming scale 8 is situated above the barrel of the weapon and in a substantially vertical plane.
  • the object of the main feature of the invention is precisely to obviate this disadvantage.
  • the scale-type aiming device is so arranged that the scale 8 when in the operative position extends in the radial half-plane of the barrel 1 which forms a substantial angle with the upper radial half-plane P of the said barrel. It is readily apparent that the same results may be achieved by mounting the aiming device so that in an operative position it extends parallel to such radial half plane.
  • the arrangement is such that the two upper half-planes corresponding respectively to firing with bullets and firing with grenades form a dihedron whose apex angle has a substantial value, which must not, of course, be 360, which corresponds to the former state of the art.
  • the rifle when the rifle is in the position for firing grenades, that is to say in a position wherein the butt rests on the ground and the aiming scale 8 extends above the barrel parallel to the vertical plane passing through the axis of the barrel 1, the said aiming scale is lowered relatively to the position of maximum elevation which it necessarily occupied when it was situated, in the operative position, in the upper radial half-plane P of the barrel 1 (the case shown in FIG. 2a).
  • the arrangement can be such that the scale 8 extends in either, as FIG. 2b shows, one of the radial half-planes P forming an angle of with the upper radial half-plane P the line of sight M being then situated, in the most unfavourable case, at a level H distinctly lower than the corresponding level H in the case of a conventional weapon, or else, as FIG. 20 shows, the radial half-plane P forming an angle of 180 with the upper radial half-plane P the sight line M being then situated at a minimum level H in the most unfavourable case.
  • the radial half-plane P which will be adopted for orientating the aiming scale 8 will preferably be that which, when it is orientated vertically and upwardly, leaves the trigger device 4 of the rifle atits right-hand side, which facilitates firing for a normal person, that is to say for a righthanded firer.
  • FIG. 3 it would be possible, more particularly and by way of example, to use the form of embodiment illustrated in FIG. 3, wherein the swivel pin 9 of the scale 3 is carried by a block 10 pivotally mounted on the body of the sleeve 6 and capable of passing, by rotational movement through 90, from a position I in which the scale 8 is orientated in the upper radial half-plane of the barrel to a position II in which the said scale is orientated perpendicularly to the said upper radial half-plane.
  • the person using the weapon can fire grenades, in the first case, as if he were using a conventional grenade-throwing riiie, i.e. keeping in a crouched position, and, in the second case, adopting the lying position which enables him to camouflage himself Well.
  • the block carrying the scale 8 is mounted to be slidable in the axial direction and pivotable on the body of the sleeve 6, the said block it is subjected to the action of a spring 11 which urges it in the axial direction into one of its end positions, for example its rear end position, the rear end of the block 10 and the corresponding region of the sleeve 6 are made to comprise matching elements (teeth 12 and recesses 13) of a toothed coupling mrangement, these elements being arranged on the one hand to be capable of cooperating by fitting in one another when the block 10 occupies its rear end position and on the other hand of being disengaged when the block 16 is displaced forwardly in opposition to the action of the spring 11, and the elements of the said toothed coupling device carried by the sleeve 6 are so situated that, once the said sleeve is in position on the barrel 1 in an invariable angular position (determined by the foresight 14 of the barrel engaging in a.
  • the invention in short, provides a grenade throwing rifle whose method of use and advantages will be sufiiciently clear from the foregoing description, so that there is no point in going into further additional explanations in this matter.
  • a portable firearm comprising a butt, a barrel rigid therewith, a grenade-throwing device fixed to said barrel and an aiming scale mounted on said barrel, the said aiming scale extending in a radial half-plane of said barrel making a substantial angle with the upper radial half-plane of the said barrel.
  • a portable firearm according to claim 2, wherein the radial half-plane in which the aiming scale is oriented is the one located on the right hand side of the firearm.
  • a portable firearm according to claim 1, wherein said aiming scale extends in the radial half-plane making an angle of with the upper radial half-plane;
  • a portable firearm according to claim 1, wherein said aiming scale is carried by said grenade-throwing device and is pivotable with respect to said device about an axis perpendicular to the axis of said device.
  • a portable firearm including a block for carrying said aiming scale, said block being mounted pivotally on said grenade-throwing device about an axis parallel to that of said barrel so as to be able to pass by rotational movement through 90 from a position in which the scale is orientated in the upper radial half-plane of the barrel to a position in which the said scale is orientated perpendicularly to the said upper radial half-plane.
  • a portable firearm according to claim 8 wherein said block has freedom of angular movement through 360 about said axis with respect to said device, further including releasable locking means for said block with respect to said device.
