Metallic Cartridge-Cases.

IMPROVEMENT IN METALLIC CARTRlDGE-CASES. l'
Specifica-tion forming part of Letters Patent No. 144,012, dated October 28, 1873; application filed August 29, 1873.
2. is also a central longitudinal section of a casefor a cartridge with the re-enforce extending the entire length ofthe case and covered bot-h exteriorly and interiorly with deposited metal. Fig. 3
represents a mandrel upon which a case is deposited in section. Y Fig. .4 shows a central longitudinal section of the re-enforce to a cartridge detached, and having a covering of nickel previous to being placed upon thelowcrend of the mandrel to receive the bodyof the" case deposited thereon.
My invention relates to a metallic case for a cartridge when made by electro-deposition, and' re-enforced substantially in the manner herein set` forth, and for the more perfect understanding of the nature of the article pro-A duced the method of fabrication is also described.l
Like letters designate corresponding parts in all of the gures.
i A in the accompanying drawings represents a mandrehof the required size and form, upon which the" case is'deposited. This mandrel, of
any suitable material, being rst shaped, is immersed infa'ba'th 'of nickel, .and .receivingV a coating, a, is removed therefrom and polished, so as to 4present a smooth surface, upon which to deposit the metal for the body of the cartridge-case, and allow of the deposited case being 'easily removed therefrom. The mandrel might lbe made of metal fusible at a low temperature, so as to be melted out after having deposited the-case thereon; or parafne,
. bees-warg, or other suitable substance mightbe employe instead of metal, in which case a covering of plumbago would be necessary to create -a metallic base upon which to commence the deposit of the metal for the cartridge-case.' In
order to re-enforce the base of the case to increase its strength a head of hard metal, B, is provided, which is placed upbn the end of the mandrell A, thereby forming the l-le'ol'i'tour or shape of which the cartridge is tof'fbe. The mandrel Awith its re-enforce B is then immersed in an electro-galvanic bath,land the metal C, of which the case. is to be formed, isv deposited thereon, covering the re-enforce'B, and extending vupon the surface of thevmandrel a sufficient distance t-o form the body thereof of the required length, as represented in Fig. l. Thus, when the whole shall have been removed from the :mandrel A, the reenforceB and deposited body C are united as one'metah and produce a case for a cartridge re-enforced with hard metal as a base 'previouslyvprepared, and having a body of comparatively soft metal. The reenforce lB may extend the entire length of the body of the case, if preferred, as represented in Fig. 2. A coating of nickel or other metal, c c, may be given to the re-enforce B over the whole of both the interior and exterior ofthe Vcase, as
shown in Fig. 2, thereby inclosing the reveniforce between the two coverings;
lThe re-enforce B may be made of malleable iron, if desired, which will admit of being swaged and shaped without cracking, or otherwise impairing its tensile strength.
A cartridge made as above described is free from the danger of any gas, upon explosion,
getting under or below the re-enforce, and has a more solid base than 1s practicable in a case made from drawn metal, while the thickest, and consequently weightiest, part is composed of a'cheaper and stronger metal,
Having thus fully described my invention, what I claim as new, is- Y A metallicl case for a cartridge re-enforced with and having a hard-metal base in intimate connection `and contact therewith, as herein described. STEPHEN W. YVOOD.
