MAGAZINE-FIREARIVI.

SPECIFICATION forming part of Letters Patent No. 589,117, dated August 31, 1897'. Application filed February 25, 1892. Serial No. 422,784. (No model.)

To all whom it may concern:

Be it known that I, ANDREW BURGESS, residing at Bualo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Magazine- Guns, of which the following is a specification, reference being hadtherein to the aecompanying drawings.

This invention relates to magazine-direarms.

The objectief the invention is to produce amagazine-gun in which the movement'. of the bolt and operating-handle may be in a slightlycurved direction in opening and closing the breech, also to improve the breech locking and unlocking mechanism, also to produce an improved detachable magazine and maga- Zine-stop, also to improve in Various particulars guns of the class described.

Figure l is a broken central longitudinal section of a magazine-gun of the character described, the carrier and some other parts omitted. Fig. 2 is a modilication, in longitudinal section, of the bolt-locking brace and connections. Fig. 3 is an elevation of the split sleeve surrounding the magazine and forming the cartridge-detent. Fig. a is a detail longitudinal section of magazine-tube and connections. Fig. 5 is a modification of the magazine, showing the cartridge-retaining fingers integral with the magazinetube- The numeral l indicates the gun-barrel, of usual construction, connected to the shoe or receiver 2 in usual manner.

. there will be an abutment 8 at each side of the frame,with a slot or opening between, and a shoulder 7 at each side of the brace, but for light charges one abutment will serve.

The locking-brace has an extension 9projecting down through a slot in the bottom of the frame, and this projection may be cx tended to form a trigger-guard and operatinghandle, as vat 10, Fig. l. To give additional strength, the handle 10 may be connected to the brace at the rear of the abutment, extending over said abutment, as at 1l, Fig. 1.

The trigger l2 is carried in the guard in such manner as to be in position to engage the se'ar13 when the breech is closed. In unlocking the breech the point of the trigger swings the sear out of its Way, the sear immediately returning to position.

The shoulder of the locking-lever is in front of the cam-face 16, which face is rigid with the tiring pin or hammer 17. A back ward pull or lift on the handle 10 carries up the rear end of the brace 5, disengaging the brace from the abutments 8 and at the same time carrying back the firing pin or hammer. After the brace is released from the abutment a backward pull on the handle carries the brace and bolt backward, thus opening the gun-breech. Thehandle follows the curve of the under part'of the frame, while the bolt follows a correspondiug'curvc of the upper part.

The firing-pin is shown in Fig. l with a curve corresponding to that of the bolt; but this is not essential,as the pin may be straight.

To close the o'peningin the bottom of the frame or shoe, a slide-piece 2O is provided, said slide-piece having a mortise 2l, through which the bar 0 of the 'handle passes. This slide is not essential, as the slot in the bottom of the frame is narrow, but the plate is a desirable feature to exclude dirt. The slide-plate 2O may move in guide-grooves 22 in the frame.

The slide-plate 2O is shown as having a handle-piece 24. connected thereto, said handle-piece extending around the lower part of the small of the stock and forming a pistolgrip. \Vhen such a handpiece is used, it will be cut away, as indicated at 25, so that the handle ma)T slide lengthwise of the frame.

rlhe advantage of the curved construction of the bolt and frame is that for some per sons it affords an easier movement than the straight longitudinal movement usual in my guns of this general character. The connec- Iss tion between the handle and bolt being direct the hand ofA the operator travels in approximately the same curve as the curve of the frame, and the bolt moving back in the depression a of the frame does not project above the body of the gun, as in other bolt constructions.

It is obvious that the top of the frame may be extended over the depression a to cover it by a simple change in construction.

In Fig. 2 the locking-brace 5 engages the abutment 8X, as has been described, but the handle IO is not integral with the brace. Said handle is pivotally connected'to a projection 3l from the lower part of the bolt 3X. 'The rear end of the'handle 10 is connected by a link l1 to the brace 5X, and the lifting of the rear end of the handle IO servesl to unlock the bolt. The rear extension 15 of the brace has a roller r, which engages the cam-face lt on the firing-pin to cam the same backward. In this modification the Sear I3 is pivoted to the locking-brace- In both modifications the sear operates to hold the hammer or firing-pin cocked, and is itself operated by the trigger to` release the firingpin in manner well known in this art.

The tubular magazine 30 is carried under the barrel and is slipped out for loading, or an empty magazine may be displaced and a full one inserted. The tubular magazine has two collars 3l rigidly connected thereto. A spring-hook 33 inthe forest'ock 34 engages one of these collars to hold the magazine in the gun, and may be operated by the finger to release the magazine.

The mouth of the magazine is surrounded by a ring 35, which ring is extended, as a split sleeve 36, the ends of the fingers forming said split sleeve being inclined inward, so as toproject slightly in front of the mouth of the magazine when free to do so. The inner faces-of these projecting endsv are inclined, as at 37, and the end of the magazine-tube may be correspondingly beveled.

When the magazine is out of the gun,it is filled with cartridges by pressing them into the opening between the ends of the fingers 36. The fingers will close behind the heads of the cartridges and thus act as a det-ent gto prevent the spring cartridge-follower 40 from throwing the cartridges out of the magazine. Y

Vhen the magazine is inserted from the l front of the forestock, the ends of fingers 37 come against the flat shoulder 4l in the frame at the same time that the spring-hook 33 engages the shoulder 3l on the magazine-tube and the magazine is simply held in place, but willV not feed, as the split sleeve acts as a detent. (See Fig. 4.) To open this detent, the magazine is pushed in farther until the spring-hook engages shoulder 32 of the magazine. The split sleeve will be then pressed farther onto the magazine-tube, as in Fig. 1,

thus expandingtthe fingers, and the cartridges will then feedback into the receiver under the impulse of the spring-follower.

The bolt maybe provided with a cartridgechcck 45, of usual construction.

The sleeve 36 is held to the end of the magazine in any convenient manner, as by a pin 43 passing through a slot 44 in the sleeve. In the modification Fig. 5 the end of the tubular magazine is slitted, forming spring fingers 50, and the ends of these lingers have inclined projections 5l. These projections close behind the headof a cartridge. When the magazine is pressed to place in the gun, a ring 52 with a beveled front entersbetween these fingers and expands them, so that they no longer act asa detent.

-I do not claim herein the constructionby which the spring-fingers are expanded, as shown in Fig. 5, the same beingshown and claimed in myapplication, SerialNo. 452,991",

5. In a breech-loading gun, the combination of the frame and bolt moving therein, the locking-brace pivoted-to the bolt and'having a bearing against an abutment in the frame, and projections from said brace in front and in rear of said abutment and extending downward to form the tri gger-guard, substantially as described.
