To all whom it may concern:

Be it known that we, ADoNIs NIooLAs GA- VARD and HYPPOLITE MILLON, both citizens of Paris, in the Republic of France, have invented certain new and useful Improvements in Needle-Guns and in the Cartridges therefor; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to the letters or figures of reference marked thereon, which form part of this specification.

The subject of the present invention is a fixed cartridge-case, into which the powder and shot or ball are placed and priming or tulminating composition added, as required, and as will be hereinafter explained.

The object of the improvements is to admit of firing the same gun at short or long ranges, according to the charge of powder or fulminate and the weight of the projectile, both of which are regulated according to the distance that the shot or ball shall be intended to carry.

The invention is applicable to arms of all calibers for chamber or saloon firing, or for the full range of the arm,without in any way interfering with its mechanism, the cost of firing being reduced to the simple expense of the powder and shot.

The cartridge-case, or breech-cartridge, as we term it, can be used for the Ohassepot, Gras, or other gun, opening and closing at the breech, whether worked by a bolt or 1ever.

Figure 1 is a section of a Ghassepot rifle. Fig. 2 is a plan of the same Fig. 3, a section of the cartridge-case; Fig. 4, a plan thereof. Fig. 5 shows the breech-opening in communication with the cartridge. Fig. 6 shows the opening of the cartridge communicating with the shaft of the bolt.

The cartridge-case for receiving the cartridge, which may be of any suitable construction, consists of an elastic metal tube, a,

] formed of thin sheet metal, one end of said tube being chased and set in the piece I). The mouth is open, like the end of the socket of a metal cartridge, while the opposite end, set in the breech, is completely closed, with the exception of a small hole which traverses the cartridge-case for the passage of the needle, which is enveloped in a small tube, a, itself formed of a thin sheet of inoxidable or any suitable metal. The end of the small tube which incases the needle for a certain length inside the case is intended to prevent the escape of gas and fouling of the needle and the hole it passes through, which latter drawbacks in the old system render the needlegun impracticable.

This cartridge-case can also be used for firing with gas or paper burning cartridges. The inflamed gases compressed inside the elastic tube press the metal sheet (of which the tube is composed) against the sides of the cartridge-chamber, which is consequently completely closed, and prevents the gun spitting. The small elastic tube (formed like the tube a) which protects the needle receives an extern a1 pressure, which prevents waste between the inside of thetube and. the needle.

In order to simplify dismounting the gun for cleaning or otherwise, at the upper part of the movable breech is a small jointed lever, d, furnished with a small stop-piece, d, which, propping against a projection, in, Fig. 1, on the end of the gun-barrel, keeps the bolt in place. This stop-piece d pivots at will, and thus allows of its being raised from the projection m and the bolt being removed. The movable breech can then be removed by pressing on the sear, so as to liberate the lower groove of the breech, which then comes out freely.

The cartridge'case is held to the bolt, as shown in the plan, by means of, a screw, Z),working in the bayonet-slot b", which allows of this piece being removed at will.

What we claim is- 1. A cartridge-shell consisting of the metal tube a, fitted in a piece, I), having a bayonetgroove, in which a screw attached to the gun tance within the tube, substantially as 'deis received, so as to lock the shell in the gun, scribed. substantially as described. A. N. GAVARD. 2. A cartridge-shell consisting of the metal H. MILLON. 5 tube a, closed at its inner end, and. further fit- Witnesses:
