To all whom it may concern:

Be itknown that I, EDWARD E. Rnnrinnn, a citizen of the United States, residing in Glendale, in the State of Oregon, have invented certain new and useful Improvements in Firearms, of which the followin is a specification, reference being had to t 1e accompanying drawings, forming a part hereof.

This invention relates mainly to magazine firearms of the general type of that shown in a pending application of the same inventor for Letters Patent of the United States, Serial No. 598,781, filed December 22,1910,

. in'which the several operations of extracting the empty shell, cocking the gun and placing a fresh cartridge in the chamber of the barrel, are efiected by the longitudinal movements of a grip-piece which is mounted to slide on the magazine tube parallel with the barrel. The improvements covered by said former application, Serial No. 598,781, are shown and described therein as applied to a higlrpower rifle.

. One of the general objects of the present invention'is to adapt the desirab e. features of the high-power rifle described in said ap-. plication to magazine shot guns of the same general type.

Another general object is to improve some of the features. of construction of firearms of the type shown in said application, whether the same are applied to a rifle or to a shot gun.

One of the specific objects of the present invention is to improv'e the construction and arrangement of the take-down devices, making the construction stronger, easier to manipulate and such that the breech pressure shall be exerted against a shoulder of the receiver forward of the take down joint and shall put no strain on thetake-down devices.

A further specific object is to improve the slide locking devices, an independent slide latch being provided and acted upon di-, rectly by the finger within the trigger guard.

The invention is also concerned with the construction and arrangement of the inertia block and its cooperation with the slide.

' The safety devices are of an ordinary type, but are arranged to be thrown to centeror safety position by the rearward or opening movement of the breechbloel The trigger mechanism is substantially as shown in said former application, comprising a trigger lever interposed. between the trigger and the sear which is mounted on the breech-block,

and cooperating with thebreech'block and sear as described therein. In the present invention the cartridge litter is modified and improved as to its construction, arrangeo ment and operation, as will be more fullyexplained hereinafter.

Although the present improvements are shown and'described herein as embodied in a shot gun rather than a rifle, it will be understood that they are capable of application to firearms of different types as well as that they are severally capable of use independently ot each other.

The invention will be more fully explained hereinafter witlfreference to the accompanying drawings in which it is illustrated and in which 3 Figure 1 is a view in side elevation of a shot gun in which the several features of improvements herein sought to be covered are embodied. Fig. 2 is a detail view, on a larger scale, partly in elevation and partly in longitudinal section through'the receiver,

frame and stock, showing the'parts in the 30 positions which they occupy when the gun is closed and ready for firing, but with the trigger locked bythe safety. Fig. 3 is a view generally'similar to that shown in Fig.

2. but with the safety off and the parts in 5 the positions which they occupy immediately I after firing with the trigger released. Fig.

i is also a view generally similar to Fig. 2, but showing the breech-block in its rearward position after having restored the inertia block to its cocked position and the safety device to safety position. Fig. 5 is a view generally similar to Fig. 4 but showing the parts in the positions which they assume after the breech-block menced its forward movement, the lifter be ing shown in its elevated position. Fig. 6 is a detail view in elevation illustrating particularly the relation of the receiver and barrel to the frame and stock in the operation of taking down. Fig. '7 is a detail view' in section on the plane indicated by broken. line 77 of Fig. 5 illustrating particularly the take-down locking devices. Figs. 8 and 9'ar e top and under side views of the takedown locking lever. Fig. 10. is a detail view. partly in side elevation and partly broken out,- showing the breech-block and some of the parts carried thereby. Fig. 11

-Fig. 16' is a top view of the inertia block. The barrel a chambered as usual to recelve "the cartridge, the magazine I) in which the cartridges are placed and are pressed to the rear by a spring follower, not. shown, the receiver 0 (except as hereinafter indicated), the frame (1 (also except as hereinafter indicated), and the stockd, are constructed ingposition sothat accidental disengageranged and operated substantially as shownin said former application 598,781,.having pivoted thereon the supporting and'starting substantially-as usual in repeating shot guns. The receiver has, forward of itsrear end, and forward of the take-down joint, a shoulder 0. against which the breech-block abuts' in the firing position, so that the breech pressure is taken bythe receiver and. puts no strain upon the take-down d'evices. In the opening ofthe gun thebreec'h-block passes rearwardly below the abutment 0 into the chamber in the .frame. Forward of the front edge (1 of the frame d, at the bottom thereof, is'a'soli'd extension 03 which su ports, one' at each side, semi-circular lugs 01 each of which is ada ted to engage a cor-. responding, semi-circu ar recess 0 1n the receiver 0, a hinge-knuckle thus beingformed between the frame and the receiver, upon which the frame-and barrel hinge in the taking down of the gun. The extension- (Z and the lugs d form also a vertical support and a forward longitudinal abutment to hold the receiver and the frame securely together when they arelocked at the top, as will now be described. In rear of the abutment 0 the receiver 0 has an extension c which is extended rearwardly and downfor operation. A spring plunger d mountedin the top of the frame, actsupon the lug d 'of the locking lever to press it normally into locking position and to hold it in lookment of the parts is prevented. These takedown devices are most clearly shown in Figs. 59. v The breech-block e is constructed, ar-

lever 1, which has a lug f to cooperate with a horizontal and a vertical shoulder on the left-hand side of the receiver, not shown, to drop the rear end of the breech-block below the abutment c of thefreceiver and 3 start the breech-block rearwardly, being 0 erated for this purpose through its engagement at the lower endwith the slide bar. The cocking lever g' is pivoted upon the starting lever f and has a lug extended through a slo-tin the left hand wall of the breech-block vto cooperate with a shoulder h of the ham-.

mer h which is longitudinallymovable in the breech-block. The hammer is thrown forward by a coiled hammer spring, not shown,

and is held in cocked position by a sear-i, also pivoted on the breech-block and'adapt is actuated by the trigger 0, 'all as described ed to be engaged'by, a trigger lever 1" which in said former application. The breeeh- I bl0ck, sear and trigger lever are shown in detail in Figs. 10-13.

The grip-piece 7c is mounted upon the magazine tube b as usual andhas extended rearwa-rdly therefrom a slide bar 70 which has at its extremity a lug k to engage the supporting and starting lever f.. In the present construction, the lower end of the starting lever is not slotted but i.-. formed with a hole' f 'for engagement with the slide bar 76 the entire-rearward and forward movement of the breech-block being ,eifected through such engagement of the. slide'bar with the starting lever f. Otherwise; the

operation of the slide bar, starting lever,

breech-block,,coeking lever, hammer, sear,

trigger and. trigger lever are substantially as described in said former application.and, as they form nopart of the present invention, except as they cooperate with" other devices to be described, need not be further ex-= plained herein.

' In the gun described in said" former ftp".

plication, the rearward movement of the slide bar M was 'prevented,-except at the proper time, by a locking lever which stood, until released, behind the starting lever and was actuated by a finger lever which pro- 'jected within the trigger guard. In-the;

present case the slide locking lever m,.p'ivoted in the frame at m has at its forward end'a locking lug m which projects upwardly within the receiver into the path of the starting lever f and at its rear end a- .button m which projects downwardly within the trigger guardin position to be pressed by the finger 'so that the lug'm shall be thrown down out of the path of the starting lever f and thereby permit the rearward mo ement of the slide bar. The locking lever m. is held normally in locking position by a spring, (see Fig. 2) and the lug m is .so shaped that the "lower end of the starting lever slips over it when the starti'ng lever is returned to the closed position. The inertia block 11 's'hownjin Figs. 2. 3 aud t, and, in detail, in-Figi 16, is preferably in the form of a rod mounted in a sleeve 01 which is seated'ina recess in'the stock d The sleeve a is held in place by a tang screw rue p h eagh he 3 also through a longitudinal slot Win the inertia block 91, thereby limiting the ,movecocked, but flies out across the end of the sleve'when the inertia block moves forward, as shown in Fig. 8, thereby acting to prevent the rebound of the lnertia block. F urther' more, when the block is moving forward the spring acts against the end of the sleeve to throw the block forward with asnap. At its forward end the inertia block has an extension 11 which is provided with an inclined or cam end n which cooperates with a cam end m of a rearward extension 171: from the slide latch or lever m so that as the inertia block moves forward (relatively) the slide locking lever or latch in has its rear end'thrown upward and its locking lug m thrown downward to permit the slide bar to be moved rearwardly. The forward extension a of the inertia block may also have a cam shouldera to engage a corresponding cam shoulder m of the slide locking lever or latch m, for the purpose of preventing rebound -of the inertia block. The extension a is also provided with a shoulder a which, as shown in Fig. 4, is engaged by the breechblock e in the last of its rearward movement, so that the inertia block is cocked by the rearward movement of the breech-block itself.

The trigger 0, pivoted at 0 in the frame, has a heel 0 in the rear of pivot 0 for co operation with the toe of the safety slide p. The latter is mounted in the usual manner in the frame and has a button p above the upper tang for convenient operation. It is preferably arranged to have three positions. In the middle or safety position, shown in Fig. 2, the toe 79 stands in the path of movement of the heel 0 of the trigger so as to prevent effective movement of the trigger, but if the button 12 1S pushed over to the front or the rear of its middle ment of the trigger. As the safety is usually pushed off by moving the button p forward, its shank'p is so formed that in the last of the rearward movement of the breech-block, as shown in Fig. 4, it will push the safety back from its forward position to its middle or safety position, so that the gun cannot be fired after reloading, until the safety is thrown off. 4

The lifter Z is shown in detail in Fig. 15 and in its relation with other parts in Figs. 2 to 6, being shown in its'elevated position in Fig. 5 only. It is slotted atthe rear, as at Z to straddle the trigger 0 and is pivoted upon the same pin 0 therewith. At its forfurnish thereby a better seat for the cartridge and reduce the liability of the rolling of the cartridge out of the receiver if the gun should be held tilted toward the right. The lifter is itself lifted, as the breech-block begins its forward movement, through the inleg tion of a lifter lever I. which is pivoted at m in the frame. This lever is shown in detail in Fig. 14 and in relation with other parts in Figs. 2-5. It comprises two parts or wings t and 25 The wing 6 stands in the same vertical plane with the cartridge stop 5 which is carried by the breech-block, and has a shoulder 27 adapted to be engaged by a shoulder a of the cartridge stop asthe breech-block begins its forward movement from the extreme rearward position shown in Fig. 4. The cartridge stop- .9 is pivoted in the breech-block and therefore moves freely over the wings 25 in the rearward movementof the breech-block and also yields to the action of the cam surface i in rear of the shoulder i as the breech-block moves forward, to permit the disengagement of the lifter lever from the cartridge stop after a short forward movement of the breech-block. The wing t of the lifter lever has a cam edge 6 which, as the lifter lever is rocked on its axis by t-he forward movement of the breech-block, acts'against the under-side of the lifter, forward of its pivot 0 to raise the lifter from'the position shown in Fig. 4 to the position shown in Fig. 5, thereby raising the cartridge which meanwhile has passed from the magazine on to the lifter intoline with the chamber of the barrel and in front of the breech-block, so that the cartridge shall be pushed into the chamber of the barrel by the continued forward movement of the breech-block. The lifter is not sustained in it's suspended position by the lever a but it has on its left-hand side a lug Z which as the breech-block moves for ward and while the lifter is still supported by the lever t, is engaged by an inwardly projecting shoulder e of the breech-block which supports the lifter in itselevated position until the nose of the cartridge has been inserted far enough into the chamber of the barrel. after which the shoulder 6 passes beyond the lug Z and permits the lifter to drop to its lowest position, as shown in F 2, 3 and 6, the lifter being impelled clownward by the action of the spring Z shown in part in Figs. 2 to t.

It will be obvious that the details of construction and arrangement shown will be varied more or less according to the. characherein nor to the joint use of all of the features of improvement in one structure.
