specincationjormiggpgrt oful etters lfatentfln. amuse, dated July'4, 1865.
G.'Donen,of inthe District ofColu'mbia, have inyented'a new. and useful Improvement ,in' MetallicCartridge-Gases"; and I do hereby vdeclare 'thatthefollowing is a full,.clear, and. exact description thereof, reference being had to the accompanying drawings, making part h- I. Figure lis a side elevation-of a ,cartridge showing my iinprovel'ne'nt applied, and-Fig; 3 is a side elevation of a metallic caseof another form, with a portionbrokenjaway to showtheinterioa The nature of my: invention i consists in or oxidizethan the. case itself, and thus pre case and its? contents from deterio -'-To preventtheseevils, I'coat'or plate the metallic case of the cartridge, before filling and other materials, with tin or anyother suitable metalor alloy, This maybe done in a variety of the coating material in a molten-"state. 0ne qitvious methods-of doing this is s eets of metal; firom'which the. -casesare to Ibemade,'-previo'us to forming them up,- ydipping the "sheets properly prepared .inmolten', tie in the usual manner of in v i p I Itlcanalso be done by immersing the case, afterithasbeen formed, into themolten tin,
{would prefer coatin 'cartridge havlinglthe fulminaieplaced in theannular. rim or flange, as is now usually done, I would prefer that the case should be tinned the last thingprevious to forming the flange, which isusuallythe last operation in the con- 'struction of the case, for the. reason that, if
tinned after the flange is formed, there will be danger of filling the flange with. the tin, which would prevent .the' subsequent placing of the 'fulminate therein. In what are termed central-fire cartridges, in which the fulminate is not placed in the flange, this-objection will notoccur, and in such the timing or plating may be done after the flange is formed.
It is obvious that other methods of applyingthe coating or plating to the case may be used;;and that gold, silver, and othermetals or alloy of metals may be used instead oftin, 7
but tin is-preferable,lbr the obvious reason that it is one of the 'most eflicient, -'.cheap'est, andeasiest applied of an for the purpose intended. It is alsoobvious that in using some kind of metals, such as gold, silver, &c., .for the coating material, it may be successfully and rapidly applied-by thewell-known galvanicf process. I I am aware improvement by boiling brasscases in a solution of tin in acid, butthe coatingthusiapplied.v was a mere film, and entirely ineflicient .for the accomplishment of the des red object;
and Ith'erefore do-not claim that.
It is obvious'that the cases may be coated onplated internally'cnlyor both internally and externally, as circumstances may require; and wherethe'cartridges are intended to be -,kept for any great length of time, and where they'aretobe used-in moist or 'warm climates,
and externally.
"Having thus 'describedmy invention, what claim-is 1 IA cartridge-case for small-arms composed of ductile metal and coated or plated interter'nally, or both internally and externally, with ti-nQor other suitable metal or alloy-of metals, substantially herein-set forth.
