The object of the presentinvention is to avoid d F Wb k" I, i i i, p 7

According to the invention, there-is provideda trigger control device intended to be usedwhen thegun is to I launchgrenades and constitutedas' follows. 1

mentsof practice than those used up to the present time,

andin particular which is less dangerous tohandle'Q Such firearms include a trigger and-a trigger guard arranged in such manner thatforlnormally firing the arm,

the soldier inserts his forefinger between the trigger and the front part of thejtrigger guardso asto'be able to pull the ;.trigger. According to the present invention; there is" provided a', trigger .control. device including an oblonglever. extending substantially in the. direction of'the linei of fire of the arm and on one side of the trigger guard, in combination with means for movably mounting said part-gen said trigger guard so that'said part can 1be ,-actuated a direction transverse tosaid line of fire ibyfthe tips of the fingers (the word finger being used specifically to designate the four extremities of the hand other than the thumb) of'the soldiers hand curved under the trigger V guard with the ball of the thumb applied against the side of the firearm opposed to that on which said oblong part is mounted, said part carrying means for engaging the trigger when said part is moved toward the trigger guard transversely to the line of fire.

Preferred embodiments of the present invention will be hereinafter described 'with reference to-the accompanying drawings, given merely by way of example and in which: Fig. l is a perspective view of a grenade launching rifle made according to a first embodiment of the invention.

Figs. 2, 3 and 4 are, respectively, a side View, a bottom view and a rear view of the trigger control device belonging to said rifle.

Figs. 5 to 8 are views similar to Figs. 1 to 4 respectively and showing a second embodiment of the invention.

The drawings show a rifle which may be used either for firing bullets in the usual way or for launching grenades by means of a launcher fitted on said rifle.

The rifle stock is designated by reference numeral 1.

In the usual fashion, trigger 2 is protected against accidental operation thereof by a trigger guard 3 constituted by a curved piece of metal surrounding the trigger.

,. Such an arrangement is quite suitable when the rifle j is firing bullets.

' On the contrary, when the rifle is fitted with a grenade launcher, the rifle butt is no longer applied against the In this case, the rifle is tightly held between the right side of the soldiers body and his right elbow, the front part of the rifle being held by his left hand; In such a position, the rifle cannot be held as 7' strongly as in the preceding case and the recoil is much more important. If the soldier inserts his forefinger be- Y tween the trigger and the trigger guard and if he does not manage to withdraw said forefinger suflicientlyquickly,

ably carried by the rifle and inparticular by the trigger :guard in such mannerthat the soldier can" move part 4 transversely by means of the finger tips of his right hand I (Fig. 4) curved, below the trigger guard and the 'ball of I the thumb of .which' is. applied against the rifle side op posed to that on Which'le've'r 4' ismounte d. Suitable means are provided for transmitting this transverse movement of part 4 to the'triggerin order to actuate'it. With such an'arrangement, recoil of the rifle is no longer dengerous because said rifle will then slip insidethe soldiers hand.

' above explained (see Fig. 4) and on the other hand the scription, disclosed what I deem to be practical and efii cient embodiments of my invention, it should be well unright hand side of the trigger guard is left free sons to enable the soldierto engagehis forefinger between trigger 2 and the. trigger guard when he is firing bullets with the rifle butt applied against his shoulder. V

Lever 4 may be permanently fixed to trigger guard 3.

, However it seems preferable to mount it in a. removable fashion, for instance by means of side plates 7 located on either side of trigger guard 3 and connected together by" means of screws 8. The left hand side plate 7 is provided with a boss in which the pivot pin 5 of lever 4 is mounted.

.The means for transmitting the transverse motion of lever 4 to trigger 2 may be made as follows:

In the construction of Figs. 1 to 4, lever 4 carries, rigid therewith, a kind 'ofcam 9 which cooperates with trigger 2 when lever 4 is moved in the direction of the arrow of Fig. 3 to pivot said trigger rearwardly. This arrangement is advantageous when the displacement of the trigger is relatively short.

When the movement of the trigger is to be longer,

it is advantageous to make use of the arrangementof Figs. 5 to 8 where lever 4 carries an extension or lever arm 10 which is applied against trigger 2 and pushes it 10 in a position such that they do not exert any rearward thrust on trigger 2.

In a general manner, while I have, in the above dederstood that I do not wish to be limited thereto as there might be changes madeinrthe arrangeinenhdisposition and form of the parts without departing from the prin- .ciple of the present invention as comprehended within the scope of the accompanying claims.

What I claim is:

1. A firearm which comprises,in combination, a stock, Q

this

Preferably, as shown by thedrawing, -lever 4 constitutes a kind of lever, of rounded shape in the'outward direction, which is pivoted to the trigger guard about an ax-is si. parallel to the plane of longitudinal 'symmetryof; the rifle and substantially at right angles to the line-of fire." 1A return spring-6 urges said -lever 4 -awayfrorn trigger guard3. Q 1

. In the preferred embodiment illustrated by the draw-' in'g, lever -4lis. located ongthe'left hand side of triggei guard 3 so that on the one hand it can be actuated as;

a trigger pivoted to said stock, a trigger guard carried by said stock surrounding said trigger, an oblong lever pivoted to said trigger guard on the left hand side thereof about an axis parallel to the longitudinal plane of symmetry of the firearm and at right angles to the line of fire thereof, said lever extending-in a direction substantially parallel to said line of fire, and its dimension in this direction being greater than the Width of the palm of a human. hand, and resilient means for urging said lever away from said trigger guard; said lever including a part shaped and positioned for cooperating with said trigger to actuate it when said lever is pushed toward said trigger guard.

2. A firearm which comprises, in combination, a stock, a trigger pivoted to said stock, a trigger guard carried by said stock surrounding said trigger, an oblong lever pivoted to said trigger guard on the left hand side thereof about an axis parallel to thelongitudinal plane of'symmetry of the firearm and at right angles to the line of fire thereof, said lever extending in a direction substantially parallel to said line of fire, and its dimension in this di rection being greater than the width of the palm of a humanhand, and resilient means for urging said lever away from said trigger guard, said lever including a cam fire thereof, said lever extending in a direction substantially parallel to said line of fire, and its dimension in this direction being greater thanthe width of the palm of a human hand, and resilient means for urging said lever away from said trigger guard, said lever including an arm rigid therewith for cooperating with said trigger to actuate it when said lever is pushed toward said trigger guard;

integral therewith for cooperating with said trigger to actuate it when said lever is pushed toward said trigger guard. p i

3. A firearm which comprises, in combination, a stock, a trigger pivoted'to said stock, a trigger guard carried by said stock surrounding said trigger, an oblong lever pivoted to said trigger guard on the left hand side thereof about an axis parallel to the longitudinal plane of symmetry of the firearm and at right angles to the line of 4. A firearm which comprises, in combination, a stock, a trigger pivoted to said stock, a trigger guard carried by said stock surrounding said trigger, an oblong lever pivoted to said trigger guard on one side thereof about an axis parallel to the longitudinal plane of symmetry of'the' firearm and at right angles to the line of fire thereof, said lever extending in a direction substantially parallel to said line of fire and its dimension in this direction being greater tha'rithe width'of the palm of a human handQand IesiIient means'for' urging sa'id'lever away from said trigger guard, said lever including a part shaped and positioned for co operating' with said trigger to actuate it when said lever is pushed toward said trigger guard.
