FIREARM.

To all whom it may concern:

Be it known that I, VVILHELM BRAUNING, a citizen of the German Republic, residing at Berlin, Germany, have invented new and useful Improvements in Firearms, (for which I have filed application in Germany Sept. 28, 1919,) of which the following is a specification.

This invention relates to the Brauning fire-arm and is of that type in which the breech-lock turns upward and carries the firing-lock with rearwardly projecting hammer or striker. The invention as compared with this existing type of fire-arm, consists in that on the countersunk or set-back breech and lock-carrying bar there is secured an angle-piece which with its horizontal end extends to the breech-locking frame and'has a furcated upright portion to serve as a guide for the striker. This furcation consists in a bore for the passage of-the rear thick portion of the striker and of an upwardly extending slot to suit the adjacent thinner portion of the striker; said slot ending rearwardly in an enlarged recess forming a rest for the retention of the striker in its safety position. As a further improvement in accordance with this invention, the extractor is slidably mounted in the set-back of the breech-bar and is kept, from dislodging, by the superposed barrel-breech.

An embodiment of the invention isshown in the accompanying drawings, in which:

Figure 1 is a side view of the breech part with longitudinal section of the stock and showing the striker cooked and in safety position.

Fig. 2 is a corresponding plan.

Fig. 3 is a side view with the stock removed and the arm in its after-firing position.

Fig. 4 is a side view like Fig. 3 but showin the open breech.

igs. 5 to 7 are perspective views of details hereinafter described.

As clearly shown in the Figs. 1 and 2, the breech-lock 7c is made in the form of a frame of flat bar-iron in which is fixed the breech-block 71 and the therethrough projecting striker b with its spring 7 The frame I: is hinged or pivoted to the breech-end h v of the barrel Z, said breech-end being firmly fixed to the breech-supporting bar s. The barrel-breech h is made of sharp-angled metal. The bar 8, made of flat metal, car- 7 Specification of Letters Patent. Patent d D 27 1921 Application filed April 30, 1921.

ries a fixed angle-piece 'w of flat metal hav ing an aperture to for guiding the rear thick portion 6 of the striker b. For cocking the striker the head Z2 of same is pulled to the rear, when the percussion pin at the front end will be retained in cocked position by the usual catch u of the detent a, see Fig. 3. The catch u is made by slitting the end of the detent u and then turning up the middle portion. The projecting fork like portions 14 are shaped to form bearings for cradling the lateral lugs 2 of the trigger a. The trigger is provided with a tip a which bears against the detent and supports same in its idle position as in Figs. 1 and 4. The trigger a is entirely made of fiat metal in a stamping and bending or shaping operation. The aperture to of the angle-piece w communicates upward with an open slot of a width corresponding to the striker-portion forward of 6 thereof, so that in cockmg the striker itsthinner portion passes up the slot and allows the breech to be opened, see Fig. 4. Above the aperture 'w at the rear of the slot is formed a recess 10 into which the part b of the striker engages aftercocking. The fire-arm is then cooked in safety position, see Figs. 1 and 2. By extending the horizontal forward end of the angle-piece w to contact with the breechframe 7:: the latter is locked from the rear, while upward turning of same is prevented by the engagement of the striker-portion b in the aperture 20 of the angle-piece w, see

Fig. 3.

The extractor :12 consists of the base plate m and the'extractor-claw the whole being made of flat metal by stamping and bending. The extractor is shiftingly carried in the set-back s of the bar 8 and is held above by the breech 71, of the barrel. Movement is imparted to the extractor, at opening and closing of the breech, in causing a suitably shaped forward end or nose of the breechframe to engage in side slots formed in the base plate m of the extractor. All locking parts together with the lock and the barrel are carried by the supporting bar 8 to which they are suitably fixed as and where required.

I claim:

1. Breech-mechanism for fire-arms which consists in a barrel with a connected squareshaped breech-piece, an upwardly swinging breechlocking device, a striker mounted slotted and recessed at the rear of the slot to accommodate the striker in its different operative positions, a catch for the striker, a trigger operatively connected with the catch, and an extractor for removing empty cartridges from the barrel.

3. Breech-mechanism for fire-arms consisting "in a barrel with a square-shaped breech-piece, an upwardly swinging breech- ].oeking frame hinged to the breech-piece, a striker mounted in said frame to project endwise therefrom, an offset breech-supportin frame, means for locking and releasing sald frame, a shiftable extractor bedded in the offset and covered by the breech of the barrel, projecting lugs on the extractor, a nose-piece connected with said frame for the engagement with-said lugs in operating said extractor, and means for retaining the striker at safety and for firing the arm.
