MAGAZINE FIRE-ARM.V

SFECIFICATION forming part of Letters Patent No. 303,262, dated August 12, 1884-.

Application filed January S, 18S/1. (No model.) v

To cr/ZZ whom t may concern.:

Be it known that I, ANDREW BURGEss, a citizen ofthe United States, residing at Owego, inthe county of Tioga and State of New York, have invented certain new and useful lnr provement-s in Magazine FireArms, of which the following` is a specification, reference bcing had therein to the accompanying drawings.

The object of my invention is to lprovide a magazine-gun of sure,simple, and rapid operation; and said invention consists in various improvements on those shown in my Patents Nos. 210,091 and 213,867 and the application of an additional magazine and changeable loading-case, together with other combinations and arrangements of parts, hereinafter more fully set forth. l

Figure 1 is a longitudinal side elevation in section withbreech closed and at half-cock, and showing the oblique magazine; Fig. 2, a similar view from the other side with breech open, and showing position of both magazines. Fig. 3 is a top view of bolt, showing theposition and relations of magazines thereto. Fig. 4 is a cross-section of Fig. l on line x x, looking forward, and shows the raised parts of bolt and frame, the butts of the cartridges in rear magazine, and in dotted lines a cartridge as just drawn from the forward magazine and in the position it takes when ready to feed into the frame. Fig. 5 is a detached view of the ejector and extractor. of the feeding and separating` lever and crosssection of same on line y y, but right side up. Fig. 7 is the loading tube or case; Fig. 8, part of the loading-case, showing` the beveled top springs, S S, holding the cartridges in the magazine. A

This gun, as shown in Figs. 1, 2, and 4, has a hollow frame, A., furnished with a reciprocating breeclrbolt, B, which is moved and locked by the oblique lever L, as shown in my Patent No. 210,091. I add a projection7 B, to the bolt, which extends vertically upward so far as to allow a inortise closed at its top for the top end of the lever to rise and turn in without protruding through top of the bolt. The top of frame at A', Figs. 1, 2, and et, has a corresponding vertically-raised portion to receive and confine the raised top of Vthe bolt, as particularly shown in cross-see Fig. Gis a bottom view v tion, Fig. 3, where A is the raised top of the `frame; B', the raised top of the'bolt; f, the

iiringpin in the first movement of opening the breech, and thus crowds back said pin. I arrange the lock in the bolt and use a spiral spring to propel forward the firing-pin f. In the head of the firing-pin is a raised part, j", which projects forward over the said pin and operating-brace, so that the brace L, in oscil-` lating upward to unlock and move back the bolt, engages said projection to move the firing-pin backward within the bolt to cock it by its scar h engaging the notch 71, in the bottom ofthe bolt.

In the above operation of cooking the gun to prevent the bolt from starting back too soon, and thereby produce objectionable fric tion of the face of the brace on its lockingshoulder, l. pivot the dog D in the bolt and furnish it with a spring, d', to turn its rear end upward to engage the notch d" in the inside ot' the frame. This locks the bolt, soit cannot start back until the abutment d (in the process of cooking the firing-pin by moving it back in the bolt) engages the forward and inner projecting arm of the dog D to force said arm outward and turn the dog out of its' engagement with the frame, and thereby leave the bolt free to move backward, as shown in- Fig. 2. The extractor is pivoted in the forward end of the bolt, and an ejector, E, split at its lower part to work in slots at the sides of and below the extractor, and its upper rear end projecting above the bolt in position to be engaged and depressed by the abutment d. in the frame when the bolt is carrying itback to the position seen in Fig. 2, and thereby its lower part caused to turn out forward of the face of the bolt to trip up andeXpel the cartridges by the assistance ofthe spring E, which acts as a spring for such effect, and also, by engaging the extractor, its other end acts as a spring for that. The extractor and ejector may be hung on different pins, as shown IOO in Figs. 1 and 2, or both on one pivot, and the spring placed between them, as shown in the moved when a less number is required.

, frame, as shown in Figs. 3 and 4, and feeds the cartridges upward to the opening O,which leads into the frame on a level with the bore of the barrel. The top of this magazine at each end is furnished with the spring-studs S S', which, springing in over the ends of the top cartridge, hold it down. in the magazine, as shown in Figs. 3 and 8, the top of the springs S S' being beveled, so that a vertical downward pressure upon them by a cartridge or loading-tube will'press them so far back as to admit the insertion of the cartridges or loading-box'. I prefer to use a spring at each end, as here shown; but by forming an overhanging abutment at either end it will serve to hold that end of the cartridge, the other spring forcing the cartridge thereunder to hold it in the magazine in substantially the same manner as when both springs are used; or a flat spring with like beveled top fixed to the side of the magazine will kspring' in to grasp the side of the cartridge, substantially as above. The top of magazine m, Figs. 3 and 4, is also furnished with a lever, T, which is pivoted in the rear top of the magazine or frame. Said lever has ashort arm, t, which projects into a longitudinal groove, t', in the bolt whent-he breech is closed.V The groovet'terminates in the abutment t", forward, so that when the bolt moves back to the open position of the breech the said abutment t, reaching the short arm t of the lever, osci1- lates itnon its pivot to turn its long'forward arm, t, inward to the position shown in dotted lines in Fig..3, which has the effect to drive the top cartridge laterally through the opening O in the frame to a position in front of the bolt, by which it will beforeed forward into the barrel by the closing of the breech. An additional lever, as t, may be pivoted in the forward part of the magazine, and its rear end interlocked with the rear lever, T, so as to be moved thereby to bear against the cartridge to the rear of its center; or the lever T may have pivoted to it an oscillating follower like that shown at bottom of magazine in Figs. 1 and 2. The magazine-follower F, Figs. 1 and 2, is pivoted to a long arm or lever, F', which is hung to the frame to the rearward of the magazine, and is provided with a spring, F, to swing the forward end of said arm and its follower F upward to raise thev cartridges in the magazine. The arm F and g itsv spring are covered by a plate or backward extension of the magazine. The arm F', with its follower, may be turned back and out of the magazine, as shown in broken lines Fig. 1, to remove the cartridges from or load them into the magazine. As will be seen in Figs. 1 and 2, I make the magazine incline forward, as its front` wall, m, rises to terminate obliquely to 'the axis of the barrel. By this construction I utilize the recoil of the arm in firing, said recoil causing the oblique wall m' of the magazine to strike the heavy points of the cartridges, to'glance and raise them upward in. the magazine, and thereby assist the action of the spring-follower, or remove any obstruction that may occur.

The magazine M may be loaded from below; but I prefer to load it from the top, and for that purpose I use a flat tube or loading-box of thin material, which holds the cartridges', and is capable of being thrust into the magazine in a similar manner to that of using the loading tube described in my Patent No. 210,182; but ihis bo-X, Figs. 7 and 8, holds the cartridges sidewise; and'I prefer to make a vertical slot 4in one or both ends, as Z Z', Fig. 7, to permit. one or both of the top springs, S or S', to snap over the top of the cartridges after the insertion of the boX, to hold them down, so they may not be pulled out with the box or forced up by the follower while the springs S S' are compressed. By usingk only the rearward slot, Z, in the loading-box M", and making it of sufficient width to permit the free movement of the arm F therein, I ain enabled to leave said loading-box in the magazine, (theouter top being cut away at Z", to allow' the feeding-lever T to operata) where it forms a part of or lining to the magazine, which may be withdrawn as fast as emptied and loaded ones inserted. I make the inner top ofloading-box extend at the top far enough upward, Fig.'7, to be easily grasped, to withdraw it from the magazine. As' an equivalent of the spring-studs of Fig. 3, I show like beveled top springs, S S', in Fig. 8, which consist of bent sheet metal, which extend downward, to be fastened to the bottom of the magazine. The forward magazine, M', is arranged on a base of similar construction and position to that described in my Patent No. 213,867, and the cartridges feed into it by the means ordinarily used in machine-guns. The reciprocating carrier is arranged in detachable relation to the bolt similar to thatin above patent, but is provided with a lever for separating the cartridges and throwing them into the frame. I show the lever T', pivoted in the forward part of the reciprocating carrier C. (It may be pivoted in the forward part by a` rear beveled short arm, to act in the same manner.) The top part of its long arm t5 is widened to pass between the cartridge on the carrier and that above, to separate them whenv it is turned into the position lshown in dotted lines in Fig. 3, so that the flange of the upper cartridge may not obstruct a backward movement of the lower one. This is effected, when the carrier starts slightly forward, by the short IOO IIO

arm if of the lever as it reaches the slightlyraised abutment a, and is turned back thereby. The spring-stud a is arranged in the fore part of the carrier, to bear against the point of the cartridge thereon as the carrier moves back, so as to permit sufiicient movement rear ward of the carrier to turn the lever in to release the cartridge (if obstructed) before the cartridge shall be engaged by the unyielding part of the carrier to force it back. As soon as the cartridge is released from the upper one,the spring a will pass it back to the rear ofthe carrier, and thereby save anylost motion that the working of the separator' would otherwise produce, so that but little more than the length of the cartridge rearward will be traveled to bring it in position opposite the opening O in the frame, when theshort arm of the lever, reaching the higher abutment a on the frame, is stopped,thereby to turn its long arm inward and drive the cartridge through the opening and into the frame forward of the bolt, as shown in dotted lines, Fig. 2. The springs S S, retiring without depression, may spring in to holdthe cartridge in the magazinc as soon as the cartridge is `pressed down to the point at which they are to hold it, and thus save the space that a downward-rotating catch depresses the cartridge.

I dovnot herein claim, broadly, the dog I), in combination with the bolt and frame, the same being shown and described in an application iiled by me May 17, 1884.

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

In a bolt-gun, a brace, L, hung at the bottom of the frame, the upper end of said brace being arranged to swing upward and backward to'open the bolt, the reciprocating bolt having a mortise extending upward through its body portion, which mortise receives the end of lever L, and a raised rib above the body of the bolt, which serves as a cover to said mortise, in combination with a frame having a top housing to receive said rib on the bolt, all substantially as described.4

2. In a bolt-gun, the reciprocating breechbolt having a locking-shoulder, the firing-pin placed longitudinally in said bolt,and having upward extension f, with inclined front face, and the locking-brace L, having upward eX- tension, which comes between said incline and the locking-shoulder, and by its combined wedge and lever action serves to move back the firing-pin, all combined substantially as set forth.

3. In the frame of a gun, a reciprocating bolt provided with a firing-pin, which moves longitudinally therein, in combination with a dog, D, hung in the bolt, and arranged to spring upward to engage an abutment in the frame to lock the bolt, and an abutment, as d, in the iiringpin to turn the dog and release the bolt on the backward movement of the firing-pin, substantially as set forth.

4. In the frame of agun, a reciprocating bolt provided with pivoted extractor and ejector, substantiall y as described, in combmation with an abutment in the frame to engage and start the ejector as the breech is opened, and the` spring E', which acts on both the ejector and extractor, substantially as specified.

5. A magazine fixed to and extending below the framel of a gun, and provided with means for feeding the cartridges sidewise and upward, substantially to horizontal alignment with the barrel, a spring or springprojections arranged to enter the top of the magazine and hold the cartridges, the portion of said projections above their point of engagement being so beveled downward thata vertical. pressure upon their top retires them horizontally to admit a loading box or cartridges, and permits them to spring back to hold said cai tridges at the lowest position to which they may need to be depressed in loading, all in combination, substantially as described.

6. In combination with the breech mechanism of a gun, substantially as described, a magazine provided with mechanism for feed ing the cartridges upward, as described.I and the spring projections S S,having the inclined tops for the purpose specified, said projections being arranged to engage the ends of a cartridge to hold it in the magazine, all relatively arranged, substantially as and for the purpose set forth.

7. Ina gun, a magazine arranged vertically at the side of the frame, an opening from said magazine through the side of the frame to de` liver the cartridges laterally, a vib ating lever arranged in the magazine, in combination with movable breech mechanism to operate said lever, and thereby move the cartridgelaterally toward 'the axis of the frame, substantially as described.

8. In a magazinegun, a magazine arranged at the side of the frame, as described, and having an opening which extends through the side of ille frame, and means to present the cartridges to a position opposite said opening, in combinatin with a vibrating lever, as T, and a reciprocating bolt arranged to operate said lever and move the cartridge sidewisc into the frame, substantially as specified.
