To all whom, it may concern.-

Be it known that I, EDUARD RUBIN, a citizen of Switzerland, residing at Thun, Switzerland, have invented new and useful Improvements in Cartridges, (which have been patented in Switzerland December 21, 1888, No. 189; in Germany January 13, 1889, No. 48,049; in Austria-Hungary June 4, 1889, No. 15,018, and No. 21,775; in France June17,1889, No. 198,998; in England June 20, 1889, No. 10,113, and in Italy June 30,1889, No. XXIII, 25,658, L, 380,) of which the following is a specification.

This invention relates to the manufacture of metal-case cartridges.

The invention will be described with reference to the accompanying drawings, forming part of this specification, wherein- Figures 1 and 2 show half-sectional elevations of two slightly-different modifications of the improved cartridge. Fig. 3 shows the bullet-holding packing-ring. Fig. 4: shows a longitudinal section of the compressed charge. The case a is of brass, tombac, or bronze. Its flange b is of the same diameter as the case and is formed by turning a groove 0 in the base of-the case a for the extractor to engage in.

The case is of straight but slightly-tapered form-that is to say, it has not the usual bottle-shaped shoulder-and the bullet d is fixed in position in the end of the case by means of a metalpacking-ringe, (shown separately in Fig. 3,) which fits tightly around the base of the bullet and within the case of the cartridge. This ring may either be an entire ring or split, and it is held in place by burring over the end of the case, as shown in Fig. 1. The bore of the arm will of course be chambered to correspond to the difference in diameter of the cartridge-case and of the pro- No. 48,049 in Austria-Hungary June 4,

and in Italy June 30, 1889, XXIII,

jectile, and so form an abutment for the front end of the cartridge-case, by which the blow of the striker is resisted in firing and by which the packing-ringis retained in the cartridgecase when the projectile is discharged.

The employment of the metal packing-ring permits of reloading the cartridge-case with the compressed charge. (Shown in Fig. 4.)

Instead of using the packing-ring e, as above described, and illustrated in Fig. 1, for the purpose of holding the bullet in the case the latter may be folded or doubled inward on itself, as shown atfin Fig. 2; but in this example the cartridge-case is not adapted for being reloaded with the compressed charge, but it may be reloaded with granular powder.

It is evident that the two inner folds of the case in Fig. 2 serve as the ring E in Fig. l and are in like manner retained in the body of the case by the inward-extending flange formed on the end of said body.

Having now particularly described and ascertained the nature of the said invention and in what manner the same is to be performed, I declare that what I claim is:

In a cartridge of the character specified, the combination, with the case and the projectile of less diameter than the case, inserted in the end thereof, of a metallic packing-ring surrounding the base of the projectile within the case, the end of the case being bent inward to form a retainingflange over the packing'ring, substantially as shown and described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

EDUARD RUBIN.
