, UNITED STATES PATENT OFFICE.
ALFRED JULLIEN, OF PARIS, FRANCE.
METHOD OF MAKlNG BLANKS FOR THE BOTTOMS 0F CARTRIDGE-CASES.
SPECIFICATION forming part of Letters Patent No. 337,771, dated March 9, 1886.
Application filed December 23, 1884. Renewed February 10, 1886. SerialNo. 191,496. (No specimens.) Patented in France November 24, 1884, No. 165,542.
To aZZ whom, it may concern:
Be it known that I, ALFRED JULLIEN, a citizen of the Republic of France, residing at Paris, in the Republic of France, have invented certain new and useful Improvements in the Manufacture of Blanks to Form the Bottoms of Oartridge-Cases,and for other Like Purposes; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to improvements in the manufacture of blanks for the bottoms of cartridge-cases and for other like purposes.
Hitherto in the manufacture of cartridgecases the blanks for forming the bottoms thereof have been cut out from flat strips of the various metals or alloys which were employed-such as copper, brass, bronze, German silver, and the likeand it has been found that for one hundred kilograms of metal placed in the crucible only about thirty kilograms of bottoms fit for making cartridgecases were eventually obtained, the remaining seventy kilograms being returned to the foundry in the course of the rolling and cutting operations. By my invention I manufacture the said bottoms with great economy by increasing the density and. consequently the resistance of the metal or alloy employed.
My improved process consists in running into a plaster mold or sand mold, or by other suitable process, with or without pressure other than that of the dead-head,with or without the employment of known means of press ure, bars which I submit to several rolling, drawing, or hammering operations. I then cut the blanks from the said bars by saws or other suitable means, the sawed or cut faces of which blanks I strike or hammer, so as to compress the grain of the metal and increase its density, bringing the blanks at the same time to the required form and dimension. In
this manner a much greater quantity of metal 5 is utilized as blanks, and denser cartridgebottoms are obtained at a smaller cost.
Another advantage of my process is the economy and the facility afforded for covering the blanks with another metal,if required, by means of a simple setting of the blank in the thin metal which it is intended to apply on the blank.
My process is applicable to all metals, whether precious or other metals, and to metallic alloys, silver, copper, iron, nickel, aluminium, tin, zinc, and the like, bronze, brass, German silver, and the like, for manufacturing all kinds of blanks for bottoms for the purpose of making sewing-thimbles, drinkingcups, saucepans, ferrules, pen-holders, cartridges, cannon-cartridges, 8m. plicable for blanks havingimpressions or not, for coins and medals,and for other similar purposes.
Having thus described my invention and the manner of performing the same, what I claim is- The herein-described process of manufac- It is also apture for obtaining blanks for the bottoms of cartridges and other like purposes, which consists in casting a metal bar or cylinder, cutting it into disks perpendicularly to the axis of the bar or cylinder,and then hammer ing the blanks on their cut faces, substantially as hereinbefore described.
