IMPROVEMENT IN CARTRIDGES.-

fpecification forming part of Lett efg Patent N0. 42,329, dated April 12, 186i.

T0 dll wlwm it mag concern Be il; known that I, SILAS ORISIIN, of the city und Staate ofNew York, h2we invented a new end Improved Cartridge for Breech-L'oading Fire-Arms and I do hereby declare that the following is a full and exaet description thereof, reference being had to th e accompanyiug drawings, and to the letbers ofrel'erence marked thereou.

In tlmt dass of breecln loading fire-erms which are opened and olosed 011 a hingedjoint, es per example in the patent of Gilbert Smith, dated J une 23, 1857, it; is found in praotioe extremely diflieult to effeet a secure packing of the joint, one whieh will positively prevent the escape of the gases genera-ted by the explosion of the charge of powder under all cireumstances. Indeed, I am not eware tl1at any known cartridge Will perfeelzly and uniform ly efiecl: this most desirable result. II; is manifest that where this defeet: exists the entire projectile foroe of tl1e explosion eannot loe secured besides which, the residuum of tl1e powder around the hiuged joint, or between the breeeh and the ordinary metal-cup cartridge, (where such is used in breech-loaders,) seriously retard, if they do 11013 entirely prohibit, tl1e reloading 0f the piece, and thus defeat the mein purpose of the breeeh-loadernamely, rapid firing.

Now, my invention obviates all these objections, and Will secure a pert'eol; paoking of the joint in all breeeh-loaders wherein it ean be used, constitute a positive eheck to the esea-pe of any gas whatever et the joint, and of course l;he deposit: of any residuum from the explosion of tl1e powder around the joint will not; take place, and the arm can, in consequenee, be fired any numloer of times in -rapid succession.

My invention eonsists in the eombination of thin pieces of sheetz-met-al With common eartridge paper rolled togelaher like an ordina.ry certridge, and. a thin paper disk, which is pierced in the oenter am] inserted into tl1e bottom of the eartridge.

In the aeeompanying dmwings, Figure 1 shows the trapezoidal-shaped piece of metal a.nd paper to form the well and bottom of the cartriclge, the metal piece terminating ab the dott;ed line a a. Fig. 2 shows the metal piece ;separate -from the paper. Fig'. 3 shows tl1e certridge charged with the ball in place. Fig.

4 shows a .centralvertical s eetion, exhibiting,

'disk or ci1p, ready 130 be inserted iuto tl1e cm tridge, ancl Fig'. 7 gives an outside view of the disk 0x cup when oompleted.

T0 enable others skilled in the art to make and use my invention, [will proceed to de seribe its construction.

From sheets of United Staates N0. 1 lahme tory pa per, by mechinery 01 otherwise, cul: of the size desired for a cartridge, and of a trapezoidal shape, as shown ab A. in Fig. 1. (Jul; also from Dress, 01 other thin sheet; metal, of about .002 of an inch in thiekness, annealed or notz, and of the same width es the paper, bat one circumference of tl1e former lessin leugth, a trapezoidal-shaped piece, like B on N0. 2 of the drawing, so that; the angular ends and sides of the paper and metal piece Shell neatly register, es seen from the dotted line a a to the line b bin Fig. l.

T0 prepare the cups or disks of peper for the botl:om of the cartridge, molsten one side of streng paper with paste, gum, or some adhesiv'e material, and roll the sheet; togeher until it becomes solid and attains the diameter of tl1e formen Gut: the roll thus formed transversely into disks, like N o. 5, of e right; thieknass, und by theepplication of pressure from either a press or puneh and die shape these disks into eups of tl1e form shown in Figs. 6 and 7, perforabing them in forming or aftex ward witl1 a small hole ii 1 tl1e center sufficient 130 permib the explosion of the eharge, but proteelsing the hole, to prevent t;he escape of powder, With a film 0f bees-wax or tallow. A common wooden cylindrical former, having one end rounded to matel1 the base of the -ohamber of the arm for which the carlsridge may be designed, and of a, gage thal: will permil; tl1e finished cartridge to fit its bore neatly, is placed upon the straight end of the paper,the rounded end being kept far enougl1 from the longest; side of the paper 130 permil: it; to projecl: when rolled far enough beyond the formal to bc crimped upon it, and rolled with in until the former is covered with a Single thickness of paper, \\hll the thiu metal piece is placed 011 the paper so as to register with it, as abovedescribed. The former is 110W pressed and rolled forward until both the paper and the metal are wrapped together upou it, and the metal is entirely enveloped in paper. The end ofthe cartridge is now eompressed over the end of the former and chocked with a chocking-string, which is replaced by a thread after the stringis withdrawn, as in making the common cartridge. The case, yet upon the former, is inserted into an iron or steel die anti a smart blow is given 130 the former by a hammer 0r mallet. The former is now withdrawn and a cup, having first bee11 dipped in any adhesive material, is inserted and forced to the bottom 0f the cartridge, which is now ready 110 be charged. The cantridge-ease thus formed receives its eharge of powder, when the ball, having a groove around its lower edge and being properly greased, is inserted and the case is compressed by Et ohocking-string, 01

detriment to my improved cartridge. It is obvious that, for protection against moisture, the outer coating of the eartridge may be coated with any suitable 01' approved water-proof V&Ifnish.

What I c1aim as my invntion, afid desire to seoure by Letters Patent, is

The combination 0f tbin pieces ot' 'sheet metal With paper aud a cup, to forma, substantially in the manner described, a finished car- =tridge for breech-loaders, for the purpose set forth.
