AUTOMATIC GUN med April 25. 1927 ii 1o 9 flm/l 5 Patented Dec. 3, 1929 CHARLES LEV, OF CANNES, FRANCE AUTOMATIC GUN v Application filed April 25, 1927,\Seral No. 186,503, and in France May 15, 1926.

The invention relates to an optionally repeating gun having fixed barrels, the object thereof being to control the mechanism for advancing the cartridges in the magazine,

.5 through an action exerted manually by the sportsman on a mechanism which, when brought into suitable position, assures complete extraction of the cartridge in the barrel, fired or not red, according to the desire of the sportsman, and this being replaced by a cartridge from the magazine.

This latter may be of different type from that which the sportsman had previously introduced into the barrel, a type which the sportsman considers suitable for shooting a kind of game which may appear unexpectedly.

In this weapon, according to the invention, the controlling element upon which the user operates to cause the weapon to operate as a repeating weapon, or to replace a cartridge which is in one barrel by another coming from the magazine, a part acts upon an ejector which is held in an operative position, such that it entirely removes the cartridge from the chamber of the barrel when the weapon is opened and, on the other hand, by a movable element formed, for example, by a Cartridge carrier which presents at the face of the barrel a cartridge designed to replace that which is to be extracted.

The invention provides particularly that this action of the cartridge carrier may be realized by means of a bolt holding this carrier spaced from the barrel, in spite of the opposing action of a. spring, when the weapon is not acting as a repeating weapon.

The accompanying drawings show an exemplary form of the invention.

Fig. l shows an improved gun according to the invention.

Fig. 2 is a perspective Vview with brokenaway parts showing an improved gun barrel of the present invention applied to a single barrel gun.

Fig. 3 shows diagrammatically the cooperation of certain elements which for clearness of the figure have been removed from their normal position. r

The figures show the weapon in its open position and the cartridge carrier 2 in its most elevated position designed to permit the introduction of a new cartridge into the barrel.

This carrier assumes this position upon opening the weapon, when this acts as a repeating arm or when the cartridge of the' barrel is to be replaced by another coming from the magazine. For this purpose this carrier is urged upwardly by a spring shown in Fig. 2, but not shown in Fig. 1.

This spring is interposed between the bottom of the carrier 2 and the box 1 forming the cartridge magazine.

It is to be noted that the carrier 2 is itself shaped in the form of a box in t-he interior of which is arranged a spring designed to assure the elevation of the cartridges in the customary manner.

The movements of the carrier 2 relative to the box or magazine 1, are guided as shown in the drawings by means of balls 6 interposed between side walls of the `magazine and those of the carrier.

The carrier 2 is returned to its lower position upon closing the weapon, due to the provision of an incline 3, upon which acts the portion 7 of the shutter forming the movable breech; at the same time this shutter pushes the cartridge to the interior of the barrel.

lVhen the carrier 2 reaches its lower position in the box 1 it is located therein by means of a bolt 2 cooperating with a notch 2m provided in one of the faces of the box which constitutes the carrier 2.

The bolt 2 is formed by a projection located on the end of a lever 12 pivoted at 12b about a vertical axis provided upon the body of the weapon. This projection toward its top carries a cut surface, cut bevelled, in such way that during the descent of the box 2, it will be laterally displaced against the efforts of the return spring 12r of the lever 12. The form of the projection constituting the above named bolt may be anything desired, and two diiferent forms are shown respectively in Figs. 1 and 2.`

The projection or bolt 2, under the action of the spring 12", traverses a channel provided in the box 1, in such manner -as to engage in the notch 2m provided upon the face of a movable portion 2. When thisl engagement is produced the movable part 2 is latcned in vits upper position. Y

As has been said above, the weapon according tomy invention can be used in variousv tridges from the barrel by the simple" act of opening the weapon, the above named ejector 8 may be putin operativeposition in known fashion by reasonx of movement .of the hammer'. It suiiices, for instance, thatthis ejector be engaged in its ino-tion somewhat before these elements are fired.

An eienient 8.a (see F ig. 3) shown. near the ejector 8 of F ig. l shows this cooperation between the ejector and the hammer mechanism shown a hammer 8l..

The element 8a which moves forward vat the saine time as the hammer,engages the ejector 8 by means oit a pin 8b rigid with this ejector.

The ejector which is thus brought into its operative position7 holds by means ot its catch the base iangeofthe cartridge which is located in` the barrel. Upon opening the 'weapon this cartridge lis ejected, and under. the action of the return spring 8T, the end of which is in Contact with the pin'Sb, the ejectorV 8- resumes its non-operative position. lt should be noted that in this case, only the ejectorV Sis moved forward because the "parti 9 forming the control: element, which has been mentioned above, and which will be described in detail. below, is not engaged in this movement. Y

"Asa result, when tlieejector 8 is put in op',-V

Verative positionby the hammer mechanism,

the,cartridgecarrier isinot freed from itsv system ot' bolts, so that upon opening the weapon this carrier remains'held in its lowerY position, which corresponds to the aetionof lie weapon as an. ordina-ry one and` not as a repeating weapon.

When the cartridge thus ejected is removed from the barrel, the'firer may replace it inanually by anotlfiery cartridge and then close theweapon. Y

l, Vhen the tirer desires to. malte the weapon actas a repeating'weapoiiVthat isnto v, when it is desired to replace the cartridge 5 tty which isin the barrel',/Wlietlier this has been tired or not,v by cart-ridge coming tronil the cartridge magazine without; perform' ing -K on, .tl'iisejector causesthe'complete ejection e first actuatesthe pushbutton. Thisa'ction upon7 ot the cartridge which islocated in the barrel. The secondresult produced by the button 6 consists in that it displace's'due to a cut face 9r and pushing member-10 in such fashion f that this pusher is made to project at .the lower part of the breech block.

The button 9 is held in its forward position against the' opposing action of the return spring 8'?" of the ejector 8'due to the tact that its lower face is provided with a hollow 9b, inv which engages the pusher l0 tensioned by a return spring l0', the tension of which is sui'icient to counterbalancethe action of a Serie 81 vien the button 9 is parte piace, it is heid in, its position. VVhile being capable et displacementto Control the ejector 8 andthe pusher l0, by means of a pin 91, engaging in a Ovroove 91a of the said button 9. l

Due to ther projection ot the pusher 10 at the lower portion et the breech block, 'uponv opening or the` weapon and toward thew end the opening movement, the end ot this" pusher lOfacts upon avslide 10', so as to ldisplace it downwardly in such manner that the conical end withv which it is provided in acting upon the arm 1-2'aof the lever l2 which carries vthe bolt 2 produces the leave of the vcartridge carrier 2,. This latter is consequentlyurg'ed to Vmove upwardly. vBy, this movement it removes the cartridgewhich. is about to be ejected by the Vejector 8, itat this moment this cartridge has not yet. fallen, and in all cases it bringsfbetorethe barrel the upper cartridge of the'vseries ot cartridges carrie'd'by the carrier. In the. case illustratedV this series is limited to two elements. z

Upon vclosing the weapon, this cartridge is introduced into the barrel innplace of the cartridge which `has been ejected; 'It will thus be. seen that, it in. the cartridge magazine there be placed cartridges of a sort ditter'ent from thosev or that of` the barrelsorbarrel, itv isV possible, if. unexpectedly :there appears a game'tor shooting tor whichl the' cartridges contained in the magaijzne are better suitable than those containedin the barrel orbarrels, to very rapidly replace the. latter by onel or more cartridges coming. from the magazine.'

Y Forithis-purpose i-tissufoient, afteig'hav- Ving exerted al pressure uponthe push button are' kept in the boX 2 of the cartridgec'arrier a gainstthe e tiert. off a Vspringeontaine d this box, andnot visible in the drawings, vdue to 1 the -fact that' the upper levers of theisa-idbor are formed by the movable paritsabout Vthe j hingess' andurged-Hte.y overhang thai-interior ing otthis bolt 2 away from the -seat'2i i of the boX 2, above named, by reason of the elastic plates such as 5. These plates have a tension such that they do not yield under the action of the pusher which tend to raise the cartridges of the carrier, but which yield on the contrary when these cartridges are positively pushed to the interior of the barrel by the breech block of the weapon when the iirer closes the latter. At this moment, further, the rising of the succeeding cartridge of the carrier is limited by the presence of the lower face of the shutter.

From all the preceding it follows that a weapon with two barrels, in accordance with my invention, may give the following combinations:

(a)` Acting as an ordinary weapon of two barrels, that is to say, after the firing, cartridges are ejected automatically by the action of the hammer upon the ejector 8.

(Z9) The weapon having been loaded, for example, with small shot in the barrel and with bullets in the loaders, it is easy to substitute the cartridges with bullets :tor those with shot in the barrels, by pushing the buttons 9 forward and opening and closing the weapon.

(c) The action of a repeating weapon by placing the buttons 9 forward either before firing or after iring the cartridges which are already in the barrels.

lvVhat I claim is:

l. Optionally repeating fixed barrel sporting gun comprising a spring elevated magazine, a latch normally holding said magazine in non-loading position with respect to the gun barrel, against the tension of said elevating spring7 tripping means for said latch, a movable breech block, said magazine and breech block being so cooperably constructed that the magazine is depressed to latched position by the passage of said `breech block over the same in the act of closing the breech, an extractor carried by said breech bloclr, selectively movable means carried by said breech block for optionally actuating the above said tripping means, a manually positionable knob carried by said breech block adapted when suitably positioned to simultaneously maintain the extractor into extracting-relation to a cartridge in the gun barrel and maintain the selectively movable means in active position with respect to the said tripping means to release said latch when the breech block is brought in its opening position.

2. Optionally repeating fixed barrel sporting gun comprising a magazine for holding the cartridge, a movable knob controlling the position vof an extractor and the operation vof said magazine, said knob acting upon said magazine through a transmission system actuated by the opening of said gun including a member having its position varied by selective manipulation of the knob, said knob being provided with a cam adapted to act upon said member upon selective manipulative movement of said knob, said transmission means including a bolt actuated by said member and releasing said mavazine.

In testimony whereof Ll have airixed my signature.

CHARLES LEV.
