JOHN M. BROWNING, or OGDENQUTA Q MAGAZINE- um srncrrrcarriouromm part t: Letters Patent'hio. 781,765,- dated February '7, 1905. Application filed July 10, 1908. .Serial No. -165, O2Q;- .f I

To tZZ tvhom'it may concern! Be it known that I, JOHNv BROWNING, a citizen of theUnited States; residing at Ogden,

in the county of VVeb'e'r and" State of Utah,

The object of the invention is to improve I the construction ofguns, especialiy in the strengthening of the barrel,'-magazine,-and stock-connection, so that the; recoil may not weaken the joint or cause the'breech-operating mechanism to work abnormally; also, to

improve the connections 'by which. the handle which reciprocates on the barrel is made toopen and close the breech; also, to improve the safety mechanisman d to place the control of the firing devices largely with an automatic mechanism actuated by the recoil or shock of firing.

The invention consists in certain constructions and combinations of mechanisms, substantially as hereinafter set forth and claimed. Figure 1 IS a broken long tudinal section of the loading and firing mechanism of the gun,

the stock and some other parts being omitted, the breech being closed. Fig. 2 is a longitu dinal section of the breech'me'chanism, the

carrier-pawldetached; Fig. 30v isa broken side view of the gun; Fig. 31, a plan'of the slide, sear-lock, and inertia-piece. I

The gun is of that class which is'operated to open and close the breech'by a handle slid 111g on themagazme, Wl'llCll' magazine is'un der the barrel. The handle, having connections to the bolt-operating=mechanism, is locked in closed position by an inertia-piece Which releases the bolt mechanism under theimpulse of, recoil when the gun is tired. Mechanism'is provided by which the bolt-operatingmechanisrn can be released by manipulaline of the barrel. The breech-bolt acts in the usual manner to impel a cartridge from the carrier into the barrel and .by its adjuncts to withdraw the shell from' the barrel and eject .it through the side of the frame. I

The numeral 1 indicates the frame or re ceiver, which is closed on top and at the rear of the barrel and is open at'the bottom. The

bottom opening in the frame is in part closed terlocking with grooves and ribs 5 in the' frame when the parts are coupled. The bar- The magazine rel, however, does-not enter into thecoupling piece from the front so far as the frame extends forward, and the coupling-piece 3 contains the rear end of the cartridge chamber. The couplingpiece-'3 is therefore of full thickness and strength between the frame and the barrel, and where it weakened at the '5 rear 'by the ribs and grooves it is not so ring-nut has a projection 11, (preferably at 1 Then by rotating the magazine-tubefi the coupling-piece 3, which keeps the magazine 'bolt 15 has a solid front except a passage for the left-hand side of, the frame.

each side.) which projection is in line with a corresponding recess 12 in the coupling-piece i 3. To lock the barrel, magazine, and coupl lingpiece to the frame, the tongues and grooves 1L 5 of the frame and coupling-piece are slipped together, as is usual, the ring-nut i being then in the position shown in ring-nut is screwed backward. The projec- 5 tion 11 on said nut enters the recess 12 in the frame'and precludes the separation of the sl i pjoint until the ring-nut is again moved forward. One end of the magazine rotates easily on the plug 7 and the other end turnsin the from moving backward or forward. The ring-nut is internally threaded, and as it cannot rotate it is screwed backward or forward by turning the magazine. The slip-joint can 1 be operated to break the gun in two when the l ring-nut 10 is out of engagement with the 1 coupling-piece. The draw-bar 36 then unhooks from its connection with the operatingslide 23, as will be explained.

The breech-bolt 15 reciprocates longitudinally 1n the frame, as in many bolt-guns. The

the tiring-pin 16. The rear part of the bolt. has a vertical mortise 1T1 therein and a curved 5 guideway 18 at each side of said mortise. A curved bolt-lock 19 is guided in this curved guideway by curved guides :20 moving in the said curved guideways.

The bolt-lock 19 has a finger 21, which enters a mortise 22 in'the operating-s1ide 23, Figs. 1 and 2. The mortise in the slide 23 is long enough to permit an independent movementor lost motion between the slide and bolt-lock. V

A downward projection 2% on the bolt-lock 19 swings down into the mortise or recess 2.3 in the slide when the backward movement of the slide 23 causes the bolt-lock 19 to move backward and downward in its curved ways 18, thus releasing the bolt-lock from the mortise 27- in the top of the frame. (See Fig. 2.)

1 hen the slide. 23 moves forward to close the bolt, the front upper end of the bolt-lock rides under the frame until it comes to the opening 27, at which time the bolt is closed. Then the loekl moves on its curved guide or slideways 18. The upper end closing'into the mortise 27am] theslide 23' closing under the projection 24 of the bolt-lock effectually holds thebolt-locii into its engagement with the frame until the slide is moved back, when a reverse operation takes place. The bolt carries an extractor-hook 28 and an ejector-hook 29, which operate to withdraw and eject the cartridge-shell in usual manner.

The firing-pin has an inclined shoulder 30, which comes directly in rear of a shoulder 31 on the bolt-loQk'when said boltlock is closed. of the bolt-lock moves back the firing-pin and causes it to remain back except when the bolt is closed and locked.

The operating-slide near its forward end a notch 34, with which a hook of handle-bar 36 engages to reeiprocate the said slide by m'ovementof the handle 37 in the usual manner. Both the slide 5 and the bolt may be held so as to move in direct line by means of ribs or grooves in the frame in the usual manner. The handle-bar 36 moves in the groove 39 in-theside' of the frame. 1 a

The groove or recess 39 is wider than the handle-bar 36 by so much as the length of the hook 35. hen the gun is coupled, the handle-bar is inthev upper part ofthe groove or recess 39. In uncoupling, afterthe ringnut is moved forwardthe tirstmovementis'to push the barrel'and coupling-piece down until the lnindle-bar strikes the bottom of the groove 39, when the handle bar is unhooked from the slide i23,' 'and the handle-bar is then moved forward. out of the groove 39, when the uncoupling may be completed.

The forward move ment of the slide 23 by engaging the arm-'49 moves the front end of the cartridge-stop down when the end of the stud 52 enters the recess 51 in the cartridge-stop, which releases the cartridge in the magazine and .allowsit to follow the slide backward as. the breechis' opened. ,When the slide has aboutcom'pleted. its backward movement, it engages the arm 1 50, which moves the rear end of the cartridge- 45 and stops the cartridge following in themagastop down and the front end up'. This. moves the recess 51 away from the'stud-52, which moves the front of the cartridge-stop inward z1ne.

The hammer 55, trigger 56, and safety-sear i 57 are all pivoted to the trigger-plate 58, (the.

trigger 56 and sear 57 on the same pivot, )fand the trigger-plate is held'in the frame by any usual means for securing the same in place, as by a screw 59 passing through the frame.

The spring 60 is split at its forward end, one

The safety-sear is shown at "the left side of the trigger, and its function is to hold the hammer in cocked position, even though the trigger be pulled, unless the breech is practically closed.
