IMPROVEMENT IN CARTRIDGES FOR FIRE-ARMS.

Specitlcation forming part of Letters Patent No. 144,01 l, dated October 1873; application nieu March 18, 1873.

To all 'whom it may concern:

Be it known that I, STEPHEN W. Woon, of Cornwall, county of Orange and State of New York, have invented a new and useful Improvement in Cartridges; and I do hereby declare that the following` is a full, clear, and exact description thereof, reference being had to the accompanying drawings making part of this speciication, in which- Figure l represents a central longitudinal section of a case for a cartridge, the body of which is composed of paper or other suitable iibrous material, and covered with metal, substantially' as herein set forth. Fig. 2 is a similar case for aV cartridge, in section, of fibrous material, having an anvil formed on its base, upon which to explode the percussion-cap, and but partially covered with metal. Fig. 3 is a corresponding section, differently formed on its interior; also covered with metal. Fig. 4 represents a case for a cartridge, of paper or other fibrous material, and necked so as to receive a bullet smaller than the main body of the case. Fig. 5 is a case for a cartridge, in section, of paper or other fibrous materia-l, and having a base or head sepa-rate from the body thereof, and covered with metal. Fig. 6 represents a similar case, in sect-ion, to that of Fig. 2, and which is provided with a re-enforcc cup, placed in the base thereof, similar to the invention of J. XV. Cochran, and which is represented as being but partially covered with metal, themetal extending only partially over the interior. Figs. 7 and 8 are still further modications of the same.'

My inyention consists in a case for a cartridge, of paper or other suitable iibrous material; or the body thereof of iibrous materia-l, combined with a base or head, of metal, wood, or other suitable material, and. covered wit-h metal, substantially in .the manner herein set forth.

It is obvious that my new case for a cartridge may be made after any of the variouslyformed inventions of this class, and the body may be constructed in one piece, or composed of several parts, constituting the whole; and as my invention does not relate to any special formof case, this description will be conned to a simple detail ot' a few of the practical methods of accomplishing` the same.,

Like letters designate corresponding parts in all of the figures.

The ina-in body of the case A is made of paper, rendered water-proof, so as not to absorb moisture in the process of being 4coated with metal, and is compressed into the required form by means of punch and die, or| shaped by any other convenient method. rlhis case is vmade by wrapping sheets of paper into a cylinder ofthe desired size, and the ilange or rim B formed thereon from the body A, as shown in Fig. 7, in which instance the base or closed end of the case may be made by folding the paper as represented in the end view, Fig. S. When the case A is made comparatively thin the base or head thereof may be re-enforced by a disk, C, of metal, wood, or other suitable material, to assist in resisting t-he blow of the hammer; or a cup, D, inserted, such as used in the cartridge known as the Berdan.7

If preferred, the base or head may consist of a separate piece, C', as shown in Fig. 5, with the body A of the. case of fibrous material, and secured thereto in any convenient manner.

'lhe paper or other fibrous materialof which this case A, or the `m ain body thereof, -is formed may be rendered proof against moisture, either In the pulp or afterward, as may be found most expedient, and by any ofthe n-elllinown processes. When the case shall have been rendered proof against moisture, a body or covering of plumbago or its equivalent is given to the surface, or to such parts as may be required, which forms a metallic base, upon which to deposit the metal forming the exterior G of the case. -The fibrous case now being prepared against moist-ure by absorption, and provided with a metallic base, is immersed in an electroga-lvanic bath, and receives a coating of metal upon its surface of any dc sircd thickness.

In preparing the fibrous material to be used in making cartridges, the plumbago, or any other suitable substance whereby a metallic base is created, may be intermingled therewith in the process of prep:trationthat is t0 sa-y, Vhait I do claim as my invention, and deintermingled with the fibrous materiel when in sire to secure by Letters Patent, is-

the pulp. A case for a cartridge composed entirely ory I desire to be distinctly understood that l in part of paper or other iibrous material, covdo not confine myself to any special form of a ered with metal7 substantial-1y as herein set case for e cartridge composed of brous mateforth. rial, orcomposed in part of fibrous material, Witnesses: STEPHEN W. WOOD. and coated luy-depositing thereon a covering WILLIAM A. SEAVER, of metal, as herein described; but P.' E. THOMAS.
