UNITED STATES PATENT FFEEEQQ MARTIN V. KAOER AND WILLIAM J. KRIZ, OF ST. LOUIS, MISSOURI.

MAGAZINE FIRE-ARM.

SPECIFICATION forming part of Letters Patent No. 282,328, dated July 31, 1883. Application filed December 7, 1882. (No model.)

To all whom it may concern:

Be it known that we, MARTIN V. Kacnn and "WILLIAM J. Knrz, bpth of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Magazine Fire-Arms, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

This improvement relates to the class of magazine fire-arms in which the cartridges are contained in a chamber in the stock and lifted into position for insertion in the barrel one at a time.

Our improvement consists in a cartridgecase constructed to receive the cartridges in an oblique position and to guide the foremost cartridge to the breech-bore of the barrel, the cartridges being advanced by a spring-follower with an antifriction wheel traveling the bottom of the cartridge-case; also, the described breech-block and cartridge extractor and mechanism for moving and locking the former and for moving the latter; also, in means for converting the gun from a magazine-gun to a breech-loader, and vice versa; also, to cer tain other details set forth in the claims.

Figure 1 is a side elevation. Fig. 2 is a detail top view. Fig. 3 is a vertical transverse section at 3 3, Fig. 1. Fig. 4 is a detail horizontal section at 4 4-, Fig. 3. Fig. 5 is a dc tail perspective View of cartridge-extractor. Fig. 6 is a detail section of hammer with faceblook up, and Fig. 7 is a similar view with face-block down. Fig. 8 is aperspective view of cartridge-follower. Fig. 9 is a longitudinal section with operating parts in elevation and in position for firing, and Fig. 10 is a similar view with the shell on point of extraction. Fig. 11 is a vertical section at 11 11, Fig. 9. Fig. 12 is a detail perspective view of the operating-lever. Fig. 13 is a detail p erspective view of the lower end of the lever-connecting pin. Fig. 14 is a transverse section at 14 14,

Fig. 10. Figs. 15 and 16 are detailperspective views, showing, respectively, the head of the connecting-pin out of and in engagement with the connecting-rod operating the sliding catch, by which the breech end of the barrel is held down in the breech-frame.

The improvement is applicable to single barreled guns or pistols, or to those having D is the barrel, hinged to the breeclrframe at E, and having at the under side lugs F, as usual, entering mortises in the breech-frame, and locked therein by a sliding catch, G. The barrel may have a single bore or any number of bores, the improvement being applicable to a fire-arm having a single bore or more.

In the drawings we show the application of our improvements to our four-bore barrel, which forms the subjcctmatter of our application for Letters Patent filed on the 5th of January, 1882.

(Z is the upper rifle bore, and d the lower rifie-bore, both located in the web between two shot-bores, d d. The lower rifle-bore, d,

and the two shot-bores d d are loaded, as

usual, by unlocking the breech and dropping the barrel.

H is a lever beneath the stock, working on a fulcrum-pin at I, and forming the triggerguard when in the position shown in Figs. 1 So and 9.

J is a T-headcd pin, which is inserted in the lever H, as shown, the head projecting through an open mortise, k, at the rear end of the co11- necting-rod K. The fore end of the connect ing-rod K is hinged to the rear end of the sliding catch G, so as to enable the drawing back of the catch to release the lugs F by the forward (and downward) movement of the lever H. This movement of the connecting-rod K 0 and slide G follows when the pin J is in its lower position, so as to bring the head j into the mortise 7., so that the backward movement of the head will cause it to impinge upon the corners 7t, whereas when the pin J is in its 5 upper position the head 7' is lifted above the mortise 7c and the neekj passes freely through the narrow mortise-inlet If without actuating the connecting-rod K. The pin J is adjusted in position in the lever H by a thumb-nut, L,

that works on a screw-threaded part, j", of the pin, the nut having a flange, Z, that turns in a groove in the lever H, so as to form a bearing for the nut.

M M are side levers turning on the fulcrumpin I, and extending down upon each side of the lever-H. These levers are notched at the lower. ends at m to receive lugs j upon the sides of the pin J when said pin is in its upper position, and thus the side levers, M, will be moved withthelever H when the lever H does not move the slide-catch G, whereas when the pin J is in position to move the catch G the lever H fails to move the side levers, the lugs i being out of the notches m.

K is a spiral spring surrounding the con necting-rod K, and 'bearing at the front end against a collar, K of the rod, so as to force the rod and catch G forward, the rear end of the spring having bearing against a part of the breech-frame suitably prepared for it.

The upper ends of the side levers, M, are connected by links N to angle-arms O, pivoted at P to the breech-block 0, so that the movement of the side levers causes the breechblock to slide in its bearings. The breechblock has side ribs, 0, working in grooves of the breech-stock,so asto be confinedtoastrictly endwise movement from its forward position, as seen in Figs. 5 and 11, where it bears against the rear end of the cartridge, to its rear position, as in Fig. 10, when it retreats to give room for the removal of the shell from the I upper rifle-bore, d.

Q is the extractor, made use of to remove the shell when the fire-arm isused as a magazine-gun. When the breech is opened by bending down the barrel 011 the pin E, the extractor D acts as usual.

The extractor Q is inserted in a socket in the breech-block, the construction being as follows: The breech-block is bored through from end to end, the central part of the bore being of smaller diameter than the two ends.

In the front part of the socket is the fore end q of the extractor Q, which is made thin, so as to spring up over the flange of the cartridge R, to engage the catch q over the flange R of the same.

Q is a screw whose stem passes through the reduced part of the socket, and whose head works in the rear enlargement, C of the socket.

S is a spiral spring surrounding the screw Q, whose rear end bears against the head of the screw, and whose fore end bears against the annular shoulder O at the fore end of the enlargement C The spring acts to draw the extractor backward until its fore end q is flush with the fore end of the breech-block. The extractor has lugs Q at top, that are engaged by the corners 0 of the arms 0 when the side levers, M, commence to move backward and the extractor is thrown forward to engage over the flange R of the shell B. At the same time that the corners 0 are moving forward the extractor, the rear ends are being thrown up to disengage their catches o from the recesses b in the breech-stock at the sides of the breech-block O. WVhen the arms 0 have reached this position, they cease to turnon the pivot P, and the continued backward movement of the side levers causes the breech-block to move backward, the extractor drawing the shell R out of the bore d and making way for the next shell, 1%, to enter the bore. The discharged shell R is drawn backward over the cartridge beneath until the flange of the one comes in contact with the flange R of the other. Then the continuedbackward movement of the extractor tilts up the discharged shell R and throws it out. The shell R beneath is prevented from following it by the insertion of its end into the bore d.

' The shells are inserted into the bore by e11- -tering the rounded ends of the bullets, (which slide up the inclined floor of the magazine,) when by pressure from the breech-block they are forced into alignment with the bore and into the barrel, the rounded ends of the bullets sliding on the upper side of the bore.

The cartridges R are inserted in an oblique position in the magazine or case T, the case being curved in such amanner at the fore end if as to throw upward the end of the first cartridge and cause it to enter the bore (1. The cartridges fit the sides t of the case, so that they are kept in line. They are pushed forward by a follower-block, U, that has a hinged leg, U, and is caused to advance by a spring, V, behind it. The leg of the follower, at its lower end, carries an anti-friction roller, a, running upon the bottom of the case. In loading the magazine T the breech-block 1s thrown back and the cartridges forced one at a time into the magazine at the front end, the cartridges pushing the follower backward.

The hammer is cooked by the downward movement of the lever H, said lever having a lug, h, to which is hinged the lower end of lifting-link WV, whose other end is slotted at w to receive a pin upon the front side of the tumbler-block Y, to which the hammer Z is attached. the lever H can be returned to its upper and backward position without drawing down the hammer, there being sufficient lost motion to allowthe upward and downward movement of the hammer when the lever H is folded up against the under side of the stock. The hammer-face strikes the firing-pin a, and the latter causes the discharge of the cartridge, as usual.

The lower position of the tumbler-block is shownin dotted lines in Fig. 9.

WVhere the present improvement is applied to our former invention in fire-arms for which we filed application in the United States Patent Office on the 5th January, 1882, the same being shown in Figs. 1, 2, 6, and 7, there are two hammers, and they are provided with sliding face-blocks 2, arranged, as described in such application, to act on the four firing-pins c. There must also be two lifting-links WV,

IIO

The slot 10 is of such length that one for each hammer. The triggers are shown at B. That firing-pin a which alone operates when the fire-arm is used as a magazine gun or pistol passes through a milled groove, 0, in the front corner of the breech-block.

It will be observed that, owing to the position of the cartridges in the magazine, (the cartridges being central fire/ nothing can at any time touch the detonating-cap, so that there is no danger of the discharge of a cartridge in the stock by any violent concussion.

We prefer to make the sides t of the magazine with ribs t, that will form a rest for the flanges R of the cartridges in case the follower U shall (from any cause) cease to act.
