To all whom it may concern.-

Be it known that I, JAMES R. I-IASKELL, a citizen of the United States, residing at Passaic, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Multicharge Guns, of which the following is a description in such full, clear, and exact terms as will enable any one skilled in the art to which my invention appertains to make and use the same, reference being had to the accompanying drawings, making part of this specification, and to the letters of reference marked thereon;

Having reference to said drawings, Figure 1 is-a longitudinal section through the primary breech of my improved gun upon the lines of its axis. Fig. 2 is a longitudinal section through the first magazine supplemental charge-chamber and also upon the line of its Fig. 3 is a transverse sectionand a rear axis. View on the line a a. Fig. 4 is atransverse section and an end view of the breech of the magazine, taken on the line c. Fig. 5 is a plan of a breech ring plate that closes each and all of the cartridge-chambers in the magazines. The figure shows this plate viewed from the rear on the line b b. Fig. 6 is an edge view of this same ring. vation of a short transverse section of the rear end of the magazine-breech. Fig. Sis an external view of the magazine, a longitudinal section of which is shown by Fig. 2. Fig. 9 is a detail to be hereinafter more fully described; Fig. 10 is a longitudinal section through a succession of supplemental magazine-chambers, taken on the line of their axes, this figure showing, also, a longitudinal external view of one-half of each of said supplemental sections of the gun. Theparts of this figure are upon an enlarged scale and are intended to show more distinctly the magazine-breech ring cap X in its different relations to the breech of the magazine. Fig. 11 is a detail, upon an enlarged scale, hereinafter more fully described. Fig. 12 is a longitudinal section of a modified form of the gun, taken upon the line of its axis, showing, also, an external view of a portion of the gun. Fig. 13

is a transverse section taken on the line a", showing, also, a rear breech view of the'prlmary magazine-chamber of Fig. 12. Fig. 14

Fig. 7 is an eleis a transverse section taken on the line'b of Fig. 12. Fig. 15' is a transverse section taken on the'line c" of Fig. 12. Fig. 16 is a gansverse section taken on the line 11? of 5p My invention consists, broadly, of a mn1ticharge-gun in which the supplemental chargechamber or cartridgechambers are made, when taken collectively, in the form of amagazine, each chamber of which concentrates upon and discharges into'the bore of tlie'gun successivelybehind the projectile in itsprogress through the'bore after the explosive of the charge in the primary breech. The c0nstruction of such' a gunwill be understood from the following description of the accompanying drawings, the features of novelty being pointed out in the claims concluding this specification.

The drawings show some of the forms in which my invention may be advantageously applied. It will be understood, however, that my invention is not limited to the precise forms herein illustrated and described, as various modifications may be employed Without departing from the spirit of my invention or the'scope of the concluding claims.

The primary breech and charge-chamber of the'gun are shown by Fig. 1. This drawing is made upon a slightly-enlarged scale and the plan of breech shown by it is old,it being the ordinary type of breech-loading breech now in common use, and which may be replaced by anyv other style or form of the breech-load ing type adapted to combine with the supplemental charge-chambers. The muzzle A of this breech-section is fitted in the breech B of the magazine. (Shown by Figs. 2, 8, and 12 of the drawings.) The breech B should be snugly fitted upon the muzzle A of the primary breech, the two parts being united together by means of screw-threads cut into the respective parts. The second and third supplemental magazines (shown by Figs. 10 and 12) are united together and to the primary magazine (shown by Figs. 2 and 8) in the same manner, substantially, that the primary magazine is united to the primary breech or section of the gun. The principal 100 part B of the supplemental magazine maybe made of any suitable cast or forged metal,

and I prefer to make 'it in one solid piece, the main bore 6, the magazine-chambers c c, and the concentrating-chamber 01 being cut out of the solid metal bysuitable boring-tools. The breech ends of the magazine-chambers c are made conical and are closed by conic sections 0, fixed to the inside of the breech ring plate 8 by means of screws P. These conic sections orbreech-cones 0 of the magazine-chambers are plainly shown on the inside surface of the breech ring plate in Fig. 6 and by dotted lines in Fig. 5. The office of this breech ring plate is to fit against the breech end of each cartridge-chamber and close them all with cone stoppers simultaneously. The operation of this breech ring plate is as follows: It is embraced, as will be seen, Figs. 2 and 10, between the breech of the magazine and the breech screw-cap X, which is made to screw to and fro on the breech of the magazine. In the breech end of the magazine pins 25 are placed to fit in corresponding holes c in the inside face of the breech ring plate 5, and in the edge of this ring plate 8 a groove Q is out, into which the pin Q enters through the screw-cap X. Assume now that the breech ring plate 3 and the breech screwcap X and the magazine-chamberc are in the position (with reference to each other) shown in the drawings, Fig. 2, to bring these several parts in their relation to each other (shown by Y, Fig. 10) the screw-cap X, which carries with it, through the agency of the pin Q in the groove Q, without turning it, the ring plate 5 until it clears the pins 2 in the end of the magazine-breech. As soon as that happens the springpin a" is forced into a hole f, made in the breech ring plate 8, carrying the ring plate round with it until the hole 0 in the ring plate comes opposite the oartridge-chamber c and the hole 0" in the screw-cap X, as shown by Y, Fig. 10. This brings the chargin g-holes c in the screwcap X and in the breech ring plate 8 opposite each other and opposite the cartridge-chamber 0 ready for loading. The spring-pin a" is driven forward at the proper time by means of a cam u, bolted to the sectionAof the gun, and is thrown back by the spring as the pin passes the cam. The charging-holes c in Figs. 3 and 5 are the same charging-holes c" in Y, Fig. 10. These holes, like the cartridgechamber 0, are diagonal to the bore of the gun, but are brought in their right relations with each other and the cartridge-chambers by the construction and operation of the breech screw-cap X and its attachments in the manner already described. Now this screw-cap, when screwed up hard in its place against the breech ring plate, will doubtless stick and be hard to start back and unscrew to open the cartridge-chambers for another charge. To meet this difficulty, I have bolted a bracket m to the periphery of the cap, against which a starting-screwin a similar bracket 'n, bolted to the outside of the magazine-chamber, is made to act and bywhich the cap X is started back from its bearings, and is then further unscrewed by a suitable wrench fitted upon pins Z, set in the periphery of the cap.

By the modified form of gun shown by Figs. 12, 13, 14, 15, and 16 the magazine form of the supplemental chargechamber is retained; but the breech of the several cartridge-chambers of the supplemental magazines are closed by separate screw breech-pins in the same manner, substantially, that the main breech of the gun is stopped, the breech-pin holders being shown by a, Fig. 13 of the drawings. The cartridge-chambers of the supplemental magazines B are shown by c, as in Fig. 2, the main bore of the gun being shown by 6, into which all the cartridges of the magazines are made to discharge, either into one common chamber or through several partition-chambers made in the muzzle of each section composing the gun, as shown by 0, Figs. 11 and 16. These figures show, also, a modified form of the muzzle ends of the several sections, the muzzle ends in this case being slotted, as at c, Fig. 14., and continued across the space (1, (shown in Figs. 2 and 10,) the lands of the rifling being continued on the solid sections or bridges between the opening 0 c c, forming the channel communicating between the supplemental cartridge-chamber and the main bore of the gun.

To insure a tight joint between the breech and muzzle ends of the several sections forming the gun, I make the joint in the form of a conic section by beveling down the muzzle ends and making a corresponding form in the breech ends, so that when the two or more sections are screwed together the two parts of the joint lap past each other, the object being to cause the expansion of the muzzle ends, due to the explosion and heat of the charge, to tighten the joint and prevent the escape of gas.

In the foregoing specification I have described what I conceive to be a good practical method of making the gun and reducing the invention to practice; but I have not endeavored to specify all the modifications which maybe employed the object of thespecification being to instruct persons skilled in the art to practice my invention in the forms which I at present prefer and to enable them toun derstand its nature, and I desire it to be distinctly understood that the forms mentioned by me of a few modifications are in no wise intended to exclude others not referred to, but which are within the spirit and scope of my invention.

Many of the details and combinations illustrated and above described are not essential to my several improvements broadly considered. All of this will be indicated in the following claims, as the omission of an element or the omission of reference to the particular features of elements mentioned are intended to be formal declarations of the fact that the omitted elements or features are not essential to the invention therein covered.

Having thus described my improvement, I claim as new and desire to secure by Letters Patent as follows:

1. In combination with a breech-section A, one or more separable supplemental cartridgesections, each section consisting of a magazine of separate cartridge-chambers arranged around and concentrating their fire into the bore of the gun.

2. In a multicharge-gun consisting of one or more supplemental charge-chambers composed of a magazine of two or more separate cartridge or loading chambers, a suitable breech piece or plate operating in combination with ascrew-cap and simultaneously closing the breech of each and all of the cartridge: or loading chambers.

3. In a mnlticharge-gnn composed of one or more supplemental charge-chambers consisting of a magazine havinga series of separate charge or cartridge chambers distributed around the bore of the gun and discharging into the same and a breech-cap X, in combination with a breech ring plate having pins or stops operating to open and close simultaneously the breech of each and all of the chargechambers.

4. In a multicharge-gun consisting of two ormoreseparatemagazine-sections,thebridges or supporting-sections formed between the opening a at the end of the muzzle of each section by which a continuity of the bearing is maintained between the several sections to carry the projectile from section to section and in case the gfin be rifled to contain the lands of the riding, substantially as described.

5. Ina mnlticharge-gun consisting of two or more separate sections joined together to form the gun,abeveled or underlapping joint between the muzzle and breech of the several sections, by which the expansion of the muzzle end, due to the explosion and heat of the charge, has the effect of tightening the joint between the two sections, substantially as described.
