To aZZ whom it may concern,.-

Be itA known that we, JOHN M. BROWNING and MATTHEW S. BROWNING, of Ogden, in the county of eber and Territory of Utah, have invented a new. vImprovement in Magazine Fire-Arms; and we do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, to bc a full, clear, and ro exact description of the same, and which said drawings constitute part of this specication, and represent, in-

Figure l, a right-hand side view of the arm complete; Fig. 2, atop'view of the same; Fig. 3,-a sectional side view looking from the leithand side, showing the parts inztheir normal position; Fig. 4, the same as Fig. 3,.,showingl the breech-piece as just commencing its opening movement; Fig. 5, a sectional view from 2U the right-haud sidc,showing the parts in their closed positiomwith the hammer cocked; Fig. (i, a partial horizontal section showing the slot .through the .carrier and the corresponding groove in the receiver; Fig. 7, a front end 2 5 view of the ex'tractorblock and transversese'c-` tion of the receiver and carrier, the position ofthe extractorblock being iu rear of its normal position; Fig. S, a transverse section of the carrier detached; Fig. 9, a sectional side view from the right, showing the breech-piece .approaching its cxtreme open position, and before the carrier commences its descent.; Fig. 10, the same as Fig. 9, but with the breech piece in its extreme open posit-ion and the carrier down; Fig'. ll, a transverse section on line a: a: of Fig. 3; Fig. 12, a transverse section on line y i/ of Fig. 3. y This invention relates to au improvement in that class of magazine fire-arms'in whichl the 4o magazine is arranged longitudinally beneath the barrel, and so as to open into the receiver below the bari-chaud particularly to that class in which the breech-piece is adapted to be operated by a handle extending downward therefrom beneath the receiver, and which forms substantially the triggerguard, the handle itself in this case being made substantially a partof thebreech-piece, parts of the invention being` applicable to single-loaders.

The object of the-invention is a simple cou-v 5o struction in which thelock mechanism maybev "V arranged entirely within the breech-piece and the hammer automatically forced to its fullcock position under the movement of the breech piece. breech-piece, carrying the entire lock mechanism, is hung t0 the receiver by a link, the forward end of the link being hung upon apivot .in the breech-piece and ex'tending'to the rea-r. The link is hung upon a' pivotin the frame or 60 receiver-,and so thatin the opening movement ofthe breech piece the link causes the rear end of the breech-piece to drop, whilethefon. ward end is guided longitudinally ih the Teceiver, by which operation the opening move- A ment of the breechpiece is produced in a. length substantially no greater than thelength ofthe breechpiece itselfLthe lock mechanism being also arranged in the breech-piece. The swinging movement of the link-is adapted to 7o act as a cam to throw the hammer to the full cock position, Where it is engaged by a scar, also hung in the breech-piece. Combined with the breech-piece isa carrier, which is adapted to be thrown down as the breech -piece approaches its extreme 'open position, so as to receive a cartridge from' the magazine, and then as the breech-piece commences its forward or closing movement the carrier is thrown upward tobring the cartridge to a position in 8o rear ofthe barrel and forward of the advancing breech-piece.

In the illustrations, A represents the receiver, to the forward end of which the barrel' B is attached in the usual manner, with the 85 magazine C below it, both the magazine and the barrel opening into a recess in the receiver at the rear, also in the usual manner, the rear end of. the breech-piece being. adapted to be secured to the stock D in any suitable manner. 9c (Here represented as by a shank, E,which extends rearward from the receiver into the stock.) .Y F represents the breech-piece, which is of a. length corresponding to the opening in the re-4 95 ceiver in rear of the barrel, its forward end Y adapted to close the rear end of the barrel and A p its rear end to rest against the rear end of the Under this construction the '55 LII recess in the receiver, as at G. The breechpiece is extended downward through the opening below the receiver and terminates in a handle, H, forming, also, the triggerguard I, thebreech-piece, handle, and trigger-guard being preferably made in one piece.

J represents a link which is hung upon a.

pivot, K, in the receiver at the rear of the breech-piece, as seen in Figs. 3 and 4. The link extends forward upon one side of the breech-piece and terminates at its forward end in a transverse trunnion, L, which extends I` the force lof resistance will come at the said point G.

In the receiver on one side of the breech- .piece is alongitudinal groove, M, (see Figs. 6 and 7,) and at the forward end of the breechpiece on that side is a stud, N, which extends into and so as to work longitudinally in the said groove M as the breech-piece moves backward and forward. f

To open the breech-piece, the handle is turned downward, the breech-piece being permitted to swing downward upon the stud N as its center of motion. At the same time the link J, being connected to both the receiver and to the breech-piece, causes the rear end of the 'breech-piece to drop, the breech -piece turning upon the trunnion L of the link and forms a pivot, upon which the breech-piece also turns, and so that the stud N, following in the groove M of the receiver,.will cause the forward end of the breech-piece to move longitudinally rearward, while the rear end will be forced downward through its connection with the link, `the breech-piece turning upon the trunnion of thelink in so doing, and until the breech-piece reaches its wide-open position, (indicated in Fig. 10,) at which time, owing to the combined action ofthe link and the longitudinal groove in the receiver, the breechpiece has assumed substantially a vertical position. Then, as the handle is drawn rearward to close the breech-piece, the forward end returns, guided by its stud N in the groove M. At the same time the rear end swings -npward under the influence -o'f thelink, until finally it is brought to its closed position. (Indicated in Fig. 5.) v v The point of connection between the link and thc breech-piece is above the point of connection between the link and theA receiver. Consequently the first part of the opening movement of the bre ch-piece, as from the position in Fig. 3 to that seen in Fig. 4, is simply to give it a downward movement on itsstud N motion, and this movement the recoil-bearing surface G in the receiver,

and as indicated in Fig. 4. From that bearing-surface downward the rear end of the receiver recedes to a sufficient extent to permit the movement of the breech-piece described, and as indicated in Figs. 3and 4; but it will be observed that the length of the opening in the receiver for the breech-piece is no greater than the length of the breech-piece, and that the entire opening movement of the breechpiece takes the breech-piece from the barrel to an extent nearly the length of the breechpiece itself, which permits the employment of the maximum length of cartridge and without an increased length of receiver, thus permitting a construction of a short receiver adapted to the longest cartridge, and whereby the weight ofthe arm is materially reduced over what is necessary in the ordinary construction witha longitudinaliy-movingbrcechpiece.

The hammer O is of tubulaishape, and is arranged in a corresponding longitudinal rccess, P, in the breech-piece, the hammer being constructed with a shoulder, R, near its forward end, and vfrom that shoulder the forward end is reduced to form the striking-point, which passes through a corresponding opening in the forward end of the breech-piece, the

shoulder R, when the hammer lis in the eX- treme forward position, being adapted to bear upon a shoulder, S, in the breech-piece, and as indicated in Fig. 3.

Within the tubular hammer a helical or other suitable spring, T, is arranged, its .for` ward end bearing against the forward closed end of the hammer, and at the rear` end the spring bears against a seat in the breech-piece. In this case the seat is represented as a sliding latch, U, which is adapted to aid in holding the breechpiece in its closed position. The tendency of the spring is to force the hammer forward, and under the arrangement shown the same spring serves to throw the` receiver, through a slot in the4 latch, and as indicated in Fig. 5. The outer end ofthe latch U is of double-,bevel shape, its nsc adapted to engage a notch, YV, in the receiver on the recoil-surface G, and as seen in Fig. 5; and thus engaged, under the action of the mainspring, this latch serves to hold the breech-piece in its closed position, but lyet, because of its double-bevel shape, permits the opening force applied to the lever to force the latchl inward against the mainspring, so that the breechpiece mayescape from its closed position, and then on the return of the breech-piece the bevel-nose permits the latch to ride into its recess to again secure the breech-piece.

The hammer upon its' under side is constructed with a shoulder, a, (sce Fig. 5,) which is the engaging-shoulder or full-cock notch. (See Figs. 9 and 10.)

b represents the sear, which is hung upon a pivot, d, eccentrically on the trunnion Lof the link J, and in the trunnion a spring, e, is arranged, the tendency of which is to bear the sear toward the hammer while the breechpiece is in the open position; but after engagement ofthe sea-r with the hammer, and in the closing movement of the breech piece, the spring is carried away from the sear, as indicated in Fig. 5, the engagement between the hammer and the sear being` suiciently strong to retain that engagement without the aid of the spring. The free end of the sear is adapted to engage the shoulder a of the hammer when permitted so to do. From-the scar atinger,f, extends downward, and is arranged -so that it may be engagedby ashoulder, g, on the trigger h, the said trigger beinghungin the breechpiece upon a pivot, t', and as seen in Fig. 5. When the parts are in the normal position, the hammer forward and free, the shoulder a of the hammer stands forward of the nose ot' the star, as indicated in Fig. 3; but as the breech-piece is turned to its extreme open position', as seen in Fig. 10, the rotative movem'ent of the trunnion in one direction and ofthe breechpiece inthe opposite directioi` causes the nose of thesear to come to a posi- Ation forward of the shoulder a on the hammer,

and as clearly indicated in Fig. 10. Then, as the closing movement of the breech-piece is commenced, the-nose of thesear engages the shoulder la of the hammer, as seen in Fig. 9, and from this point tothe closing movement the hammer and sear will retain their engagenient, the result of which is that the hammer will be forced to the rcar to the extent that the shoulder a stands forward of the nose of the sear in its normal condition, and consequently the hammer will bev brought to fullcock, as seen in Fig. 5, in .which condition the finger fof the sear is in a position to be engaged by the trigger when it is pulled, and by a pull upon the trigger thesear will be drawn down out of engagement with the hammer, as indicated in lroken lines, Fig. 5, leaving the hammer free be thrown forward under the action of its mainspring. Because of this arrangement of t-he sear and trigger, it will be observed that the nger of the scar is forward of and out of the reach ofthe trigger until the breech-piece is brought to its closed position.

To lock the trigger, so as to prevent its possible engagement with the sear in the fullcock position, I arrange asliding dog, l, in the i trigger, forward of its pivot,with a downward projeeliomm, therefrom .through the trigger into the triggerguard, and `so that the dog may be thrown forward onto a corresponding keeper, n,

impossible; but if the dog l be drawn rearward, as indicated in Fig. /then the trigger will be free, and may operate the -sear when in the iullytlosed position. The projection mis in a position forward of the finger bearing uponlc as indicated in broken lines, Fig. 5, and thus the pull of the trigger wi-ll be trigger, so that it may be readily forced forward or drawn rearward by the same finger. This trigger-locking device is provided as a safeguard against accidents.

The breech-piece is provided with an extractor. This consists ofa block, r, hung upon the side of the breech-piece upon a pivot, s. (See Figs. land 2.). This block is upon the side, of the receiver opposite the groove. Ou the extractor side of the breech-block the receiver 'is cut down so as to form a straight longitudinal guide,y z, which is parallel with the groove m upon the opposite side,v and this block fr rides upon the guide tin the opening and closing movement oi' the breeci-piece, so as to maintain its longitudinal or parallel position irrespective of the rotative movement of the breech-piece.`

At the forwar end ofthe block r, as seen in Fig. 6, the extra tor-hook-u'is arranged. This hook is in the form of abolt adapted to slide transversely inA the block r and under the action ot' a spring, w, the tendency of which is to force thc nose ot' the extractor-hook inward, the forward end of the extractor-hook being beveled, so as to ride over the flange of the cartridge as the breech-piece approaches its closed position, and in the usual manner ofextractor-hooks; butas the hook presents substantiallya square or rightangular surface upon its rear side it engages the flange of the cartridge, as seen in Fig. G, and so thatthe breechpiece, in its'opening movement, will draw the exploded shell or cartridge, it' it be not cxploded, in the usual manner of extractors,and because of the extractor being longitudinally guided it maintains its hold upon the cartridge or shell throughout its movement.

The ejection of the cartridge is through the right-hand side of the frame and over the guidi ing-surface on which the slide r rides, this opening being clearly seen in Figs. 1, 2, and 6.

A shoulder, 2, is provided at. a point stationary with relation to the rearward-moving breech-piece and upon'the side of the breechpiece opposite the extractor, this shoulder being at a point forward of the extreme rear position of the extractor, and so that as the breecl1- piece approaches its extreme rear-movement, as indicated Ain Fig. .6, the ilange of the eartridge or shell will strike the said shoulder 2, as indicated in broken lines, Fig. 2, opposite the extractor, and then, as the extractor complete's its rear movement, the shell or cartridge being arrested by said shoulder 2,-anzd still under the influence of the extractor-hook,will cause the cartridge or shell to turn outward,

as indicated in broken'lines, Fig. 6,and be .ejected from the arm.

So far `the invention is applicable alike to kboth magazine and single loaders.

As a magaziuearm the carrier 3 is bling upon a pivot, 4, at the rear, and upon the grooved side of the receiver the carrier is constructed with alongitudinal slot,5, correspond 'ing from its forward end to near its extreme rear end with the groove M in the receiver, and so'that in the normal position the carrier stands up and in line-with the barrel, the slot piece approaches its extreme rear movement itsstud N will actupon this oblique portion 6 of the slot 5, and thereby impart the downward or dropping movement to the carrier, and so as to bring it into position to receive the cartridge from the magazine, as indicated in Fig. 10, and so that when the carrier is in its down position a cartridge will be forced from the magazine onto the carrier in the usual manner for magazine-arms. Then, as the breechpiece commences its forward movement, the stud N, working through the oblique portion 6 of the slot 5, forces the carrier upward, as

indicated in Fig. 9, and so that the cartridge will stand in direct line with the barrel. Then as the breech-piece moves forward it strikes -the rear end ot' the cartridge and forces the cartridge forward into itsplace in the barrel. To arrest the cartridge when it has completely passed ontothe carrier, theshoulder 2 is formed on the carrier, as seen in Fig. 10. This is the same shoulder which serves to aid in the ejectment ofthe cartridge, as before described. To prevent the cartridge from being thrown from the carrier in its suddentransfer from the maga: zine or iu the sudden movement ofthe carrier, an overhanging linger, 7, is formed on the carrier, as indicated in Fig. l2;A and because of the ejection of the cartridge from the side of the arm the opposite side of the receiver may be constructed to overhang the breech-piece and recess in the receiver, and as indicated in Figs. 2, 7, and 8.

The magazine is charged from the under side, and when the parts are in the normal condition. 'lo do this, achute is formed by a i portion, 8, of the under side Aof the breechpiece, and a continuation, 9, thereof formedas a part ofthe carrier. (See Figs. 3, 5, and l2.) These parts, when in the closed position, as seen in Fig. 3, form, with the sides of the receiver, a groove or recess to conduct the cartridges directly into the rear end ofthe magazine. To hold the cartridges as' they are thus introduced, a latch, 10, is hung in the part 9 ot' the carrier, as seen in Fig.,5, which will yield, as indicated inbreken lines, for the passage ot' the cartridge into the magazin-Y but will drop in rear of the head of the c,v tridge' under the action of the latch-sprng ll.
