MAGAZINE FIRE-ARM.

SPECIFICATION forming part of Letters Patent, No. 289,972, dated December 11, 188$.

I LL66 whom, 6 may concern/.-

Be it known that I, ANDREW Bunenss, a citizen of. the United States, residing at Owego, in the county of Tioga and State of New York, have invented certain new and useful Improve ments in Guns, of which the following is a specification, reference being had therein to the accompanying drawings.

Figure 1 is a plan section'ot' thegun with top of frame, bolt, and 1ocking-bloek removed, showing the operatingslide S and other parts in a closed or locked position. Fig. :2 is the same unlocked and started to open. Fig. 3 is a side view of thesamc. Fig. 4 is a plan view with part of frame cut away to show a modifieation, in which the locking shoulder is solid and the lug for operating the lockingblock projects through a slot in the opposite side of the frame. Fig. 5 shows the side of a boltgun and position of reciprocating slide when the breech is open. Fig. 6 shows the same having the breech closed, and with the addition of gearing to change the movement. Fig. 7 is a side view, showing the relation of boltand carrier. Fig. 8 shows a vertical 1ongitudinal elevation of a gunprovided with various improvements. Fig. 9 is the same in an open position; and Fig. 10 shows the front of the carrier of Figs. 7, S, and t), with the stud to modify its operation. Fig. 1 is a section of Fig. 1 on line a: a. Fig. is a-seetion of Fig. 3 on line a z, to show dovetail groove s. Fig. 9 is a plan of part of Fig. l), to show the groove through which the cartridge-flange may rise. Fig. 10 isa detail showing the lever u in plan and in perspective.

Similar letters of reference indicate corresponding parts.

A is the frame; A, the bolt; B, the lockingblock; B, the lug on said block; S, the operating-slide; R R, the studs or friction-rollers of said slide; S, the handpiece for operating the slide S.

The frame A, Figs. 1, 2, 3, and t, is provided with a longitudinally-reeiproeating bolt, A,

' which is locked and moved by the laterallyswinging block B. The block B is furnished with lug B, which projects at an angle from the bolt. I arrange a sliding bar, S, to engage lug B through a slot or mortise in said bar. The engaging shoulders of bar S may be simply ronnded; but I prefer to provide them Application filed July 12, 1883.

(X0 model.)

with the friction roller-or rollers R, Figs. 1, 2,

and 4. The sliding bar S is eonfinedto a reciprocating motion in the frame by a dovetail groove or housing, as \Vhen the barS is forced rearward by the hand-piece S, or otherwise, its forward shoulder, as in Fig. 1, engages the forward portion of the inclined lug B of block 13, thereby pressing said block into the hollow of the bolt and freeing it from its locking-shoulder 15 in the frame, as seen in Fig. 2. This allows the boltto be freely moved back by the continued movement of the bar S, to open the breech, and the breech may be closed by the return movement of the bar S, and when it reaches the position shown in Fig. 2 the outward pressure of the rear shoulder of said bar turns the block. laterally, to lock it before the locking-shoulder 13.

It will be seen that I change the line or angle on both sides of the lug i, so that pressure of the bearings of the slide S will be at or nearly at a right angle with the movement of the bolt when it is unlocked, and thereby avoid the friction of amore. lateral pressure.

The slot or mortise may be made in the lug B, and a single stud or friction-roller to work therein be carried by the sliding bar S.

In Figs. 1, 2, and 3 the lug B moves backward in a slot through the locking-shoulder of the frame; but in Fig. 4 I arrange the operating-lug on the side of the frame opposite the loading-opening, so that said slot may not weaken the frame on the locking side.

In Figs. 5 and 6 I show the sliding side bar, S, arranged to engage the handle of the belt of an ordinary bolt-gun, and operate to open and close the breech by the direct rec rocating motion of said bar and its handuece S. The rearward part of bar S is widened and curved to fit the rounded form of the frame A, and provided with a diagonal slot, 8 s. This slot ineloses the base of the bolt-handle H, (on which I prefer to arrange a frictionroller, R,) as seen in Fig. (3, with the bolt closed and locked. A backward movement of the slide S presses upward by its diagonal abutment at .9 against the handle or projee tion R on the bolt, to force it up and turn said bolt so far as to unlock it, when it will attain the position relativelyto the slide S shown in Fig. 5, iind be free to move backto open the breech, an 1 then, movingthe slide S forward, will carry LII IOO

position, i arrangethefixed gearavhee-HV, Fig.

ti, to engage cogs on the slide-bar S, and a corresponding;- coggred bar to engage the opposite side of the gearwheel. This last bar is attached. to the inside ol' the hand-piece 5', so that; 'thc'forward movement: ot. said hand-piece, by an airing the bottom of the gear-wheel, iorces its top, and thereby the eoggcd slide 5, backward. to open the breech; and areverse motion of the handpiece closes the breech in a similar manner.

Fig. 1' is a side view, showing the cartridge underthe frontot'thebolton tlmearrier in the position it; takes on ljtlllg loaded into the magazine, the depression r: in the carrier at lowing the head of the cartridge to tall out of engagement with the notch n of the bolt, to pass forward into the magazine, or to enter under said notch when the bolt is closed. When the boltstarts to open, (the cartridge i'ollowing rearward by impulse of the magazinespring,) the cartridge-flangeis confined between the notch n and the top ofearrier until the flange reaches the rearward depressiomc, of carrier, which allowsthe said flange to drop to disengage from the notch 01' the bolt and re main stationary while the bolt passes rearward from over the cartridge, when it may be raised by the :arrier in the ordinary way.

in Figs. 8, t), and 10 I show a notch, c, or recess, shaped to receive the head of a can (ridge as it comes; l'romthe magazine in top or fXODtilltiOOf the ca z'rier, and a stud, 5 ,to bridge said. notch and ali=-w the cartridge to pass over it onto the carrier when the breech is fully closed. and the carrier is down, as in Figs. 7 and S; but when the carrier slight ly raised, as in Fig. it), or as shown in dotted lines in Fig. 7, the rear wail of the notch. c obstructs the passage of the artridge-ilange, and so cuts oi't'the feeding l'rom the magazine. The ear ricr can be partly raised, as shown in Figs. 7 and it), by means similar to that. claimed in Patent No 235,201, or by spring 1 or a pi'ojectiim, a. Figs. 8 audit), on the bolt.

A. red, i), is arranged in. a tube. This tube is fixed in the angle bythe sides of and partly between the barrel and magazine. Therodl) has s ning-pawls p, which enter the magazine through slots to grasp the cartrid; swhcu the breech is closed, as in l ie. *5, but when open,- as in Fig. 9, the spring pushes back the rod 1), and drives the lower inclined part, ol' the pawls against; and up the shoulders 31 in the magazineahns retiring the said pawls from ongagement; with cartridges, as in Fig. 9 1ml; when the breech-bolt; mores to close, its :t'ace engages the rear end of rod 1), m1d,ii.ircing it ibrward, compres es the spring 0, and allows the pan/is to enter the magazine. The bolt; A" liaison extractor, 1?),01; each side, and an ejector, 1*], is hung in the bolt. The face ofejector projects forward ot'the face ot. the bolt, and is caused to strike upward, to expel the shell when thebreech is opened,by the pin c,which projects inside the frame, and a projection of the ejector enters a groove, r/, in the frame,to lower it when the breech is closed. The open in; in the top of the iirame,1 igs. S and J, is narrowed at; a, so that; the flange of the rising cartridge may thereby be stopped, but; is wide enough for the body to pass, as seen in dotted lines in Fig, 8, there being a cut-cutie rearward et' said narrowintgto allow the flanged head of the cartridge to be ejected through it.

A lever, (1, is hung in the. frame, Fig. 9,and its forward short; arm is bcveled,so that when the carrier rises the side of its beveled ear st riiies the bevel on said short arm of thelever (,?',to rock said lever on its pivot,and projects its long rear arm into the t'rame,a1nl thereby holds the rising cartridge upon they carrier.

I prefer to hang the lever C vertically in the frame, when a projection at the bottom. the. carrier will strike its lower beveled arm, :0 operate said lever and close in its top arm to hold the cartridge in the manner just described.

The ext ractors may be made with elongated points which are beveled from below, so as to stop the flange of rising cartridge in a similar manner to the narrowing-r.

Having thus described my invention, what I claim. as new, and dcsire to secure by Letters Patent, is-

1. 1n abreechdoadhre gun,the combination of a longitudinally-rcei proeating breech-bolt,a longitudi nall vreciprocat ing handleplacedton ward of the frame, and connecting mechanism, substantially as lescriheihwhereby the reciprocation ol' the handle will operate the bolt.

J. in a breech-loadinggun, the combination of a loueitudi nally-rcciprocat i ng brcech-b0lt3,a

longitudinal ,"-r(':ciprocating sleeve, forming a handle, arranged forward of the frame under the barrel, so as to move in a line parallel therewith, and a strap or bar connecting said sleeve to the bolt, sotlial; the bolt; may be operated thereby.

8-. In a breech-loading gumthe combination of a reciprocating breech-bolts], locking-b10ck pivoted thereto, a reciprocating handle placed forward of the frame, so as to move in line with the barrel, and connecting mechanism, substantially as described, from the handle to the locking-block, whereby the block and bolt are moved'by the movement of the handle.

l. in a breech-loading gun,the combination of a reciprocating bolt, a lockingdilock pivoted thereto, a reciprocating handleplaced forward of the frame, so as to move in line with the barrel, a bar comiecting said handle with the locking-block, and inclined bearings, substantially as described, between the locking-block and bar.

5. In agnn, the geaewheol \V, fixed forward and outside otworking mechanism of the gun,

the cogged sliding bar S to operate said mechanism, in combination with the hand-slide S under the barrel and forward of the frame, when said slide is furnished with the cogged bearing S, to engage the gear-wheel and reverse the movement of the parts, substantially as and for the purpose set forth.

6. In the frame of a magazine-gun, a bolt provided on its under side with the notch or teeth a, to engage the cartridge-flange, with a carrier having a top bearing substantially parallel with the movement of the bolt, and a depression, 0, in said bearing, to permit the engagement and disengagement of the cartridge-flanges, all in combination, substantially as set forth.

7. A carrier provided in its face with the notch c, of suitable form to receive the head of a cartridge as it comes from the magazine, which is arranged, as described, to stop the cartridge, and an inclined face below said notch, in combination with a frame having the fixed bridge g, and means, substantially as described, to partly raise said carrier.

8. The red I), provided with the pawls or notches p p, in combination with the magazine and spring 0, when said rod is moved backward to retire said pawls from the magazine by said spring, and pushed forward into tl.e magazine by the closing movement of the breech mechanism, substantially as described.

9. A bolt provided with opposite side extractors, the engaging hooks or teeth of which project toward each other to engage the cartridge-flange between them, in combination with a frame having a groove extending upward from the rear of the extractor-teeth, to permit the cartridge-flange .to rise upward through the top of the frame, and a narrowing portion just forward of the extractorteeth, to stop a rising cartridgeflange, substantially as specified.

10. In the frame of a magazine-gun, a bolt provided with side extractors and with an ejector which strikes the flange of the cartridge upward from between said extractors, in combination with a fixed point in the frame to operate said ejector, substantially as described.

11. In combination with the frame of a magazine gun, a lever (as C) pivoted therein, and a moving carrier, the parts being arranged substantially as described, so that the carrier, in rising, will engage one end of the lever and swing the other end over the line of movement of the cartridge, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
