MAGAZINE-GUN.

SPECIFICATION forming part of Letters Patent No. 378,661, dated February 28, 1888.

Application filed December 14, 1887. Serial No. 257,850. (No model.)

To otZZ whom, it may concern:

Be it known that I, RoswELL F. Coon, of Ilion, in the county of Herkimer and State of New York, have invented certain new and useful Improvements in Magazine Guns, of which the following is a specification.

My invention relates to magazine-guns ofthat class in which the parts are operated by means of a guard-lever; and theinvention consists in a carrier-block having a sliding breechblock mounted therein and arranged to be locked in position for firing by a brace on the end of the guard-lever; also, in a peculiar arrangement of the mainspring in connection with the hammer and trigger, by which it is made to act on both; also, in a novel safety device which is made to lock the lever fast and also lock the trigger, so that the gun cannot be red, and in various minor details, all as hereinafter more fully described.

Figure l is a side elevation, partly in section, showing the parts in firing position. Fig. 2 is a similar view showing the position of the parts when the breech is open. Fig. 3 is a similar view taken from the opposite side showing the breech closed; Fig. 4, a similar view showing the breech open; and Fig. 5 is a transverse vertical section on the line x x of Fig. 2.

The barrel A and magazine-tube B may be made in the usual form, and are connected to the stock by a vertically-mortised receiver, C, as shown in the several figures, this receiver C having on the top of each cheek-piece just in rear of the end of the barrel an inwardlyprojecting lip, m, to serve as stops for thepivoted carrier D.

Instead of the ordinary breech-block I provide a carrier-block, D,which is pivoted tothe side walls of the receiver at a point below the line of the bore, the pivot being indicated by d, and which, as shown by the dotted line in Fig. l, is below the lower wall of the bore, said dotted line indicating the position the lower wall of the bore would occupy if pro longed backward, so that when the carrier is thrown down after firing the gun there is nothing in rear of the cartridge-shell, which thus has a free and unobstructed passage when thrown out by the ejector. This carrier D is operated by the guard-lever L,pivoted at N, said lever having a prolongation, L,which projects upward and forward, as shown in Fig. l, and works in a slot formed in the center of the carrier D for the purpose of operating the latter, and also moving and locking the breech-block I, as hereinafter explained.

As shown in Fig. l, the arm L of the lever L has a pin, b, projecting from one side, which pin bears against the curved lower edge ofthe carrier D, as there shown, and as the lever L is drawn back this pin forces the carrier D up to the position shown, and which is the position it occupies when the gun is fired. At its rear lower corner the carrier D is provided with a depending arm, Z, against which the pin b strikes as the lever is thrown down, thereby throwing` the front end of the carrier down to the position shown in Figs. 2 and 4.

The breech-block I is an oblong rectangular piece of metal mounted in the carrier D in such manner as to slide freely back and forth therein, the carrier being made in box form for that purpose, as shown more clearly in Figs. 2 and 4, the top wall of the carrier for convenience being made of a separate piece and made to slide and fit in grooves in the side walls of the carrier, though the carrier may be made of a single piece, if desired. rIhis breechblock I is but about half as long as the carrier, so that when thrown back to the rear end of the carrier, as shown in Fig. 4, there will be room for a cartridge in the front end of the carrier, as shown by the dotted lines in Figs. 2 and 4. In order to enable this breech-block I to be moved by the lever,it has a slot or mortise cut vertically through it for the arm L to work in, as shown more clearlyin Fig. 2. On its under side, at the front of this slot, it has also a downward projection, the rear face, n, of which is inclined, as shown in Fig. 2, and againstwhich the end of arm L bears when the gun is closed, as shown by dotted lines in Fig. 1, this arm thus acting as a brace to hold the breech` block Ifirmlyin position when the gun is fired. These parts are so proportioned and arranged that during the first part of the movement of the lever L the end of arm L is moved upward and out of contact with the shouldern, thereby unlocking the breech-block, and as thclever L continues its movement the arm Lis thrown up into the slot in the breech-block I, and its rear face,working against the rear wall of the IOO tridge by the time it.is down opposite the. mouth of the magazine, the cartridge being: ;forced from the magazine into the carrier by a coiled spring'in the magazine, in the usual manner.

The iring-pin O (shown in Fig. 4) consists of a flat bar having enlargement on it, as shown, and is set in a correspondinglyshaped groove or recess made in the side of the breech-block, the recess in which the enlargement rests being made enough longer :than the enlargement te permit the pin to have the necessary movement to re the cartridge, and also to permit its front end to be drawn back of the face of the breech-block, as shown clearly in Fig. 4, and to thus draw it back its rear end has a lateral projection, t, as shown in Fig. 2, against which the arm Lstrikes at the instant or just before it begins to move the breech; block backward, and as it remains thus retracted when the breech is closed and until struck by the hammer all danger of a premature explosion by the protrusion of the firingpin is prevented.

The hammerHis madein theform of anearly-straight piece, and is pivoted on the same pin ll as the vlever L, as shown in Fig. 4t. In order to cause the arm L to automatically cock the hammer as the breech is opened, the hammer is provided near its upper end with a lateral projection, 1', (shown more clearly in Fig. 2,) against which the rear face of arm L bears as it is moved backward, thereby forcing the hammer back until it is caught and held by the nose of the trigger T, as shown in Fig. 4.

As shown in Fig. 4, the mainspring Sis arranged to serve the twofold purpose of a main and a trigger spring, and this is effected by prolonging the trigger in rear of its pivot I), and forming on its upper face at its rear enda shoulder or hook, h, against which the rear end of the spring engages, while its front end rests in a notch or groove in the rear face of the hammer just above its pivot, the spring being bent or curved, substantially as shcwn, so that it exerts its force longitudinally, it pushing forward on the hammer and backward and downward on the rear part of the trigger at the same time. By thisarrangement I dispense with the use of a separate spring for the trigger. I also provide a safety-catch, (shown clearly in Fig. 1,) it consisting of a slide working in a slot in the guard-strap R, and having a hook, f, which, when the leveris closed, iits into a recess formed in the lever, and when shoved forward engages with a pin, c, passing transversely through the lever, thereby locking the lever fast, so it cannot be thrown down until the safety-catch is shoved back, On the upper face of the guard-strap a flat piece, z', is secured to the safety catch f, so as to move with it, the front end of said piece engaging over the rear end of the trigger when shoved forward, as shown in Fig. 4, thereby preventing the trigger from moving andA preventing the gan from being fired. This safety-catch is provided with a small projection, g, shown in Fig. l, which serves as a thumb piece to move it forward or back. It will thus be seen that it servesthe twofold purpose of 'locking the lever L fast, and at thelsame time locks the trigger.

For ejecting the shell of the cartridge from the chamberof the gun I provide a Hat-faced ejector of the form shown in Fig. 5, it iitting in a recess cut in the rear end of the barrel en three sides of the bore, and so arranged that its two vertical arms will engage with the front face of the flange of the cartridge on opposite sides, and thus exert an equal force on both `sides of the shell, and tend to pull it straight backward,instead of tending to make it cramp or bind in the bore, as is the case where the force is applied at one side only. This ejector has its body or stem curved backward below the bore, as shown in Fig. 1, and is pivoted to the wall of the receiver at seme distance below andin rear of the end ofthe barrel or bore of the gun, it being pivoted on a screw, a, as shown in Figs. l and 5. Its stem is prolonged backward beyond its pivot ct, and this stem or arm is struck by pin or projection, p, on the side of the carrier, said pin being shown in Fig. 3 and in dotted lines in Fig. l. This pin so located as to strike the arm of the ejector close to its pivot a, so that a small movement of the carrier after the pin hits the ejector will impart to the upper end of the ejector a very quick and comparatively long movement, so as to throw the shell entirely free from the gun, the pin of course not hitting the extractor until the carrier has been thrown down far enough to bring its upper face below the bore, so that the shell when thrown out will 4pass along above the carrier, the upper face of which is grooved or hollowed longitudinally to form a guideway for the shell. This also affords a most convenient means for inserting a cartridge in case it is desired to use the gun as a single-loader, it only being necessary to throw the carrier down to that point and slide the cartridge along on top of the carrier until it enters the chamber.

In order to load the magazine B, I provide a small door, G, at the under side of the receiver, as shown in the several figures, it being provided with a spring-catch, 7c, to fasten it shut, and which is released by shoving it back. This door G is provided with a stud, o, on its inner face of such a length as to bear slightly against the lower edge of the cartridge, while the lower edge of the carrier-D bears slightly against the upper edge of the cartridge, by which it is prevented from being pushed out of the magazine until the carrier is thrown down to the proper position to receive it.

It will be observed that the hammer is entirely concealed, and to uncock and let it down IOO it is only necessary to throw down the lever L far enough to bring its arm L in Contact with the projection r on the hammer, then release the trigger and slowly move the lever to its closed position, the hammer at such time being held by its contact with the arm L and gradually moving with it.

From the foregoing description any person skilled in such matters will readily understand the construction and operation of the gun. It makes a very light and smoothly-operating arm, with very few springs or delicate parts to get out of order, and with the safety arrangement is rendered far more safe from accidents.

Having thus fully described my invention, what I claim is l. The combination, in a gun, ofthe pivoted carrier D, having the sliding breech-block I mounted therein, and the pivoted lever L, provided with the arm L', having the proj ection b thereon, said arm L being arranged to engage with the brecch-block, all being constructed and arranged to operate substantiall y as shown and described.

2. The combination, in a gun, ofthe carrier D, pivoted at its rear end to the receiver at a point below the line of the bore, the sliding breech-block mounted in said carrier, and the pivoted lever L, having its arm L arranged to engage with and operate the carrierand breechblock, substantially as herein set forth.

3. The combination, in a gun, of the pivoted guard-lever L and trigger T, with the sliding safety-catch provided with the hook f, to engage with the guard-lever, and with the plate or slide i, to engage with the trigger, whereby said safety-catch is caused to lock both the guard-lever and the trigger, substantially as shown and described.

4. In combination with the sliding breechblock I, mounted in the pivoted carrier D, the firing-pin O, provided with the lateral projection t, and the arm L of the pivoted lever L, arranged to engage with the projection on the firing-pin, all being constructed and arranged to operate substantially as and for the purpose set forth.

5. The ejector E, provided with the vertical arms arranged to engage with the flange of the cartridge at opposite sides of the saine, said ejector being pivoted to the side wall of the receiver at a considerable distance below and in rear of the rear end of the barrel, as shown, in combination with the pivoted carrier D,' provided with thepin or proj ection p, arranged to strike the arm of the ejector directly in rear of its pivot, whereby a rapid and long move ment is given to the ejector, substantially as and for the purpose set forth.

In witness whereof I hereunto set my hand in the presence of two witnesses.
