tionin such full, clear, and exact -terms as will enable any one skilled in the art to whichmy invention appertains or with which it is most f nearly connected 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.

By Figure 1 of said drawings is shown a` longitudinal section through one form of my improved gun. tudinal section through a gun made upon the same general principle as that shown by Fig.

consists of making the vgun of several transverse sections, as will be particularly desig nated in the claims concluding this specification.

In the drawings, which show my invention applied in forms which I now prefer to employ, the tirst section is the breech of the gun and contains in itself the charge-chamber, as in an ordinary breech-loading gun. The gun as a whole is made by uniting to this breech-secdrawings of a single casting or forging, and

if they could be so made it would be very difficult, if not impossible,to get such casting or forging without iiaws that would be fatal By Fig. 4 is shown a longi-I eral sections-can be in process of construction at one time upon different lathes and by different workmen, Whereas if the gun be made of one forging or casting only one lathe can be used in its construction at the same time and not more than one or'two workmen can be advantageouslyemployedupon it at the same time, thus necessitating a long time -andgreat expense to make the gun, and, moreover, by making the gun in sections, as illustrated,the openings from the supplemental charge-chambers to the bore of the gun can be made long or short, wide or narrow, large or small, as may be necessary to insure `a free discharge of the gases from the pocket behind the projectile.

The following is a description of the ac-v I companying drawings, which show some of The object of my invention is to facllitate the construction of multicharge-guns; and it l the forms in which my invention ma be advantageously applied. It will be un erstood that my invention is not limited to the precise forms herein illustrated or described, as various modilications may be employed without departing from the general principle of my invention or the scope of the concluding claims.

In the gun illustrated by Fig. l of the drawings, A is the breech containing the primary charge-chamber.

B is the first section, containing the first supplemental charge-chamber C. This charge chamber or pocket is formed upon the muzzle of the gun A by boring out or casting the rear end of section B big enough to form a pocket of the desired size, the sections A and B being united by means of screw-threads D,

cut in the two sections in the manner shown. To the section B the section F. is united and forms the supplemental pocket F, the same asin the case of section B, and to the section E the section G is united, the same as before, forming the supplemental pocket H around the muzzle of the section E, the muzzle of IOO f in Fig. 5.

which section is fitted snugly into the breech of the preceding section upon a diagonal plane, as shown in the drawings. In the muzzle of each section are cut three slots, as shown by f in Fig. 2, by which three openings are formed, leading from the bore of each section to the supplemental pockets C, F, and II, the supplemental pockets being annular chambers inclosing the muzzle of each section composing the gun, as shown by H', Fig. 3. The object of the openings f is to admit to the pockets the Haine from each preceding charge and ignite each succeeding charge behind the shot or shell as it moves forward into the bore of the gun and to provide ample space for the escape of the gases from the supplemental chambers to the bore of the gun. The several supplemental pock-l ets of the gun are charged through primingholes, which are stopped by breech-plugs O, having interrupted screws, the same as are now in common use in breech-loading guns. These priming-holes are made in one or more sides of the supplemental chambers, as may be required, and each chamber is iitted with as many cleaning-holes, which are also fitted with interrupted screw plugs, as may be thought necessary to thoroughly clean the pockets.

The same principle of construction as that above described is found in the gun illustrated by Figs. 4, 5, and 6; but in the gun of Fig. 4 the several sections composing it are strengthened by bands shrunk upon the Several sections forming the gun, and in this casev the construction of the gun is further modified by additional internal sections A', B', C', and D', upon which the sections A", B", E", and Gr" are closely fitted or shrunk, the several sections being united by screwthreads, the same as in Fig. l.

The communication between the several pockets in Fig. et and the bore of the gun is obtained in the same way as in Fig. l-viz., by means of slots cut in the muzzle or forward end of each section, as shown, also, by To prevent the escape of gas through the joint between the sections B' and B" and between C' and E", aring Q of steel or some suitable metal is inserted between the ends of sections B' and C and extended up above the joint between C and E", the intention being that the expansion of the gas in the pocketwill force the ring out against the joint tight enough to prevent the escape of gas from the pocket through the joint between the inner section C' and the outer section E", this ring to be inserted between the ends of each internal and external section, so as to effectually close the joints between the two. To prevent the powder from running out of the chambers c through the opening f into the bore of the gun7 collars c" are made around the forward end of each section at the base of the openings fand bridges f'. By these means the chambers can be loaded lip gis formed on the inside section at the i rear of the chamber. The forward end of this lip on its outside is chamfered off to form a beveled seat against the outside section B the object of which is to form a gas-tight joint between the two parts, it being in tended that the explosion of the charge shall force the lip out against its seat, so as to close the joint absolutely. To accomplish this, in the construction shown in Fig. et a flange h is made on the internal section, out of which the lip g is made, and in the rear side of this flange pins t' are inserted to fitin corresponding holes in the external section to prevent the possibility of the two sections from being twisted out of their right relations. It will also be seen that the inner tube of the gun is formed by the inner longitudinal sections A', B', C', and D', connected together longitudinally by the external sections A", B, E", and G", the gun depending for its longitudinal strength upon these external sections, a mode of construction that differs from all other modes of construction used in built-up guns, in which the internal sections have been composed of one continuous tube upon which the longitudinal strength` of the gun depends.

I have stated that in the construction of this gundthe openings or slots f cut in the muzzle end thereof, by which bridges or sections of solid metal are left between the openings, may be omitted, the openings being made in the form of a ring, as shown by s', Fig. 4:; but I prefer to make the gun with the bridges at the end of the muzzle, so as to forrn a continuous bore for the projectile, the lands of the ritiing being out on the bridges between the openingsf, as shown in Fig. 5. By adopting this mode of construction there is no unnecessary space left to be filled with air or gas and the density of loading is much greater, and, moreover, the openingsf may be made from thirty to fifty per cent. larger in area than the bore of the gun, which becomes necessary to equalize the pressure due to the change in direction of the gas-pressure from the pocket to the bore of the gun through the openings f.

In the foregoing specification I have incidentally referred to a few of the modilications which may be adopted in the practice of my invention; but I have not endeavored to specify all the modifications which may be employed, the object of this specification being to instruct persons skilled in the art to practice my invent-ion in its present preferred forms and to enable them to understand its nature, and I desire it to be distinctly understood that the forms mentioned by me of a IOO IIO

IIS

few modifications are in no way 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 inventions, broadly considered. All this will be indicated in the concluding 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. 1

Having now described the structures e|n` bodying my improvements in multichargeguns, I claim as new and desire to secure by Letters Patentl. A multicharge-gun consisting of a breechsection, combined with one or more supplemental sections, one or more of said supplemental sections to be provided with an independent charge-chamber charged with any suitable explosive and opening into the bore of the gun and dischargingits load behind the advancing projectile subsequent to the explosion of the breech-charge.
