P e it known-that I, JULIEN WsRNANet-i CREoN, gun-maker, subject of the King-off Belgium, residing at" 'Hoigne.- Gheratte,

near Liege, Belgium, have invented certain new and useful Lmprovementsin-Automatim Rifles; and I hereby declare the following to be a dull, clear, and exact description of-the;

same, [such as will enable others skilled in the art to which it appertains to make and;

f cess which :is engaged by the shortarm use the invention.

. The present invention relates toan auto-' matic r fle constructed so as to provide an efiective fastening, that is to say, .a positive locking of the breech-bolt to the arm with; the objects of preventing .the escape of the.

power of penetration.

The improved rifle is of simple construe-" tion and: easy to disassemble.

F igure' 1 of the annexed drawing repre sents a longitudinal section of the improved rifle, showing the firing mechanism cocked and the bolt thrown back. Fig. 2 is a similar section but shows the parts in the posi-j tions they assume when thetrig er is pulled and the hammer is released. 3 is a transverse section on (Fig. 4 is a horizontal section on .CD (Fig. 2), showing the bolt in plan. Fig 5 is a part longitudinal section through the .breech-cas- 'ing and showingthe left side of the bolt in elevation. Fig. 6 represents an elevation of the left-hand side of the ee.- .Fig. 7 shows a part section on E F (Fig. 2) the safety device being in engagement with the trigger. v

The cylindrical breech-bolt 1 i s inclosedwithin a casing '2, which is solidwith the barrel 3, and is carried and guided by the frame or shoe 4; wherein also the .firin-g I nechani'sIn of therifle is' fitted. The belt contains the firing -pin5,. guided by the screw 6 and the spring 7 whose tendency is to force the said firing pin rearwardly.

The magazine 8 is located in front ofthe, trigger-guard which 'forms part of the shoe orframe 4, and it is secured in position by the nose 9 of a pivotedcatchlever 1 0.wh1ch engages in-a ,notch in the-magazine and which can be disengaged *by operating the pusher 1-1 at the en of the catch lever :10. The firing andloeking mechanism consists of a hammer ;12 mounted on an axis-1? carried by the frame or shoe 4, to which 1s. also fixed the firingspri'ng 14. w 'lhetngger:

v is located in airecess ofthegsaid tr and which tends ,aglso :t'o engage the sear :18 with .a notch in the hammer This trigger L5 v ilfi'and -is indintained carries at :the back .a part '19 forming aredeasing and through ithernedium oat which the trigger '15 engages with the sear 18.

The bolt 1 is provided with a latera'l -r e- :of .the cranked orbent end of a sliding rod or limb 21 which is guided laterally in the .franre 4 and whose front part is surrounded by the are-action spring 22. flhis spring 22 bears at the rearend against the frame of the rifle, and at -the frontagainst a washer so that-the said rod =and\-the nut 23, which Y is connected to it, are norma'lly mai-nta-ined in a ztor'ward position. The sliding "21 and the spring 22- are located in a casin 24 which is arranged under the barrel, -an wherein there is also mounted, a sliding oross-piece 25, which traverses withinslots 26 tor-med through side walls oat :the casing 24. This cross-piece carries lateral" projections 27, which cover the slots 26- and-are adapted to serve as pushers' tor the .manipailation odit-he-breech-bolt. T etravel of slide 25, on which the tr o 1; \ext'remi the rod 21"bears is limited at :the tront the-screw or-pin :28.

The pivot 13 of the hammer 12 is provided with a squared. part on which the hammer is mounted while the ends of the said 'pivot have {their bearing in the side walls of the breech casin '2. 'This pivot l-3 carries at one of its en 8, and outside the breech 2, a lever {29, which thefirer operates forcockin the hammer for the first shot,- as will behescrigbed thereafter. The locking of the bolt -1 is effected by a j-limb .30 pivoted (either inthe breech-casing 2 or .on the shoe pr-frame4,=) 'upon :the pin .31, which passes through the ham end ,of-

the said lim b, while its rear end rests'on the front face of the}hamm er 12, above the pivot 13. This limb '30 *has near"the"j top,'-a nose 32 which enters into engagement-with the notch =33 of bolt 1 when the parts of the rifle are in their fired positions. and the hammer is released (iii .2).

To cock the rifle, be ore firing :the first shot, the shooter brings the hammer i1 2 into engagement with the-sear by operating the lever 29 so as to turn this latter from the position represented in dotted lines Fig. 6, into that shown in full lines. By then drawing the slide 25 rearwardly, the bolt 1 is brought through'the medium of the sliding rod 21, into the position represented in Fig. 1, after which the said slide is released and. both the bolt and the rod are restored to their normal position by the s ring 22. By this forward movement of t e bolt a cartridge is pushed out of the magazine 8 and introduced into the chamber of the barrel 3. If the trigger 15 which .is pivoted on its pin 16 is then pressed, ,the piece 19 will lift the rear arm of the sear 18, whose front nose will be disengaged from the hammer 12. This latter then strikes the firing pin 5 and fires the cartridge in the chamber of the barrel 3. At the same time the locking limb 30 is turned from the position shown in Fig. 1 to thatof Fig. 2, where the projection 32 '5 within the notch 33 of the tiring bolt. T16 force of the explosion tends to turn the locking limb downwards about its pivot 31, which causes a certain pressure to be exerted on the hammer 12, in the direction of the hammerpivot, or approximately in that direction. The result is that the hammer is temporarily locked or wedged in the fired position (Fig. 2) so as to momentarily resistor opose the rearward movement of the recoilng breech-bolt and prevent the escape of the powder ases at the breech until the bullet has le t the barrel and thus a great power of penetration is imparted to the projectile.

As the force of the explosion overcomes the resistance caused by the above-described action of the locking limb on the hammer, said limb and hammer are automatically returnedto the positions shown in Fig. 1. That is, the hammer is automatically recocked and the locking limb 30 left in po'si: tion to be again swung upward, by the hammer, when the trigger is pulled. When the sear has been lifted by the jointed piece 19 at the rear end of the trigger 15, the nose 34 of this piece 19 meets the end of the frame or shoe 4, of the rifle, so that it turns rearwards, and disengages itself from the sear 18 for the purpose of again engaging below this latter under the action of the small spring 35 immediately the trigger 15 hasbeen released by the firer, and w mm the front nose of the sear 18 is rengaged in the notch of the hammer 12. Under the effect of the recoil the bolt 1 is driven rearwardly, which causes, in the well known manner, the extraction and the ejection'of the empty cartridge, the cockin of the hammer, and the introduction 0 afresh cartridge in-the chamber' of the barrel 3. The same movements are then repeated.

As long as the cockiug'is effected by the recoil and the shooter does "notoperate the slide 25, this latter remains immovable at the front of the casing 24. In the example represented, the mechanism is completed by a safety device arranged under the shoe 4 and behind the trigger ard. It consists of a sliding piece, provi ed with a head 36 which the firer operates, and is forked at the front to engage above the sear-releasing member 19 and to thus lock the trigger 15 when,the arm'is put into its safety position (Fig. 7).

It IS obvious tha this mechanism is ap licable to other arms of the same type to t lat shown in the drawings and that the rifle above described and represented in theaccompanying drawings can under details various constructive m ilications without departing from the nature of the invention. I

Having fully described my invention, what I desire to claimand secure by Letters Patent is 1. In an automatic firearm, the combinaanism to engage the breechbolt so that when the gun is fired the force of the recoil will be directed against the relatively stationary support of the firing hammer and rearward movement of the breech bolt momentarily checked. v

3.
