Niran rares Parisist* FFCE@ IMPROVEMENT 5N lVlLDS FOR RIFLEUBALLS.

Specification forming part ci' Letters Patent No. Sifll, dated September 1S, 1860.

To LZZ whom it may col/warn.-

Be it known that I, LEWIS EVANS, of Morgantown, in the county of Monougalia and State of Virginia, have invented a newA and useful Improvement in Molds for Molding Ritle-Balls; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawingstbrmin g a part of this specification, in which-v Figure l represents a perspective view. Figs. 2 and 3 are vertical sections showing the parts ofthe iniplenientsin dil'lerent positions.

Similar letters of reference in each of the several figures indicate corresponding parts.

The nature of my invention consists. tirst, in two iasks ot' a bullet-mold and a die-car rier, furnished with dies, hinged toget hersu b stantially as hereinafter described.

It consists, second, in the combination ol' a sliding cutter with the :dasks and die-carrier and dies in the mannerhereinafter described.

By-niy invention hollow bullets are east, swaged, and trimmed.

To enable others skilled in the art to make and use my invention, l will proceed to describe its construction and operation.

The two i'lasks A l. forming the bulletinolds, are hinged together at C and provided with handles l) P, by means ol" which the llasks can be opened (see Fig. 3) or closed. (See Figs. l and 2.) The upper i'lask, A, is made with cylindrical holes E, extending clear through the flask, while the lower flask is provided with conical recesses D, the centers ot' the recesses D being in line with the centersol" the vholes E when the flasks are closed. i lhe diameter of the holes E is somewhat smaller than the diameter of the top oi' the conical recesses, so that the metal when poured into one of these molds will form a Vbullet the shank ol" which is of somewhat smaller diameter than the base of its conical top. This affords a eonvenient means for securing the packing around the bullet. A bar, J, extending from an arm, H, hinged to the flasks at C, carries the dies L, one for each bullet-mold. The shanks N of the dies project through holes inthe die-earrier, and are held upward by means of spiral springs O. A stop, M, at the forward end ot' the diecarrier regulates the dept-h to which the dies enter the molds.

lt will be observed that the metal to form the bullets is poured into the large end of the mold instead of at the small end, as usual. Thus pouring in the metal enables me to have a sharp conical end on the ball 'without iinishing by hand. A plate, F, is made with slots Q at its ends. Guide-pins S, projecting from the iiasks A through said slots, confine the plate to a horizontal motion. The rear end of the plate is hung to the arm H by means oi' a link, G. rFlic plat-e is also provided with holes*one to each bullet mold-the front edge of each of these holes being beveled so as to form a sharp cutti 11g-edge, l. The bullets having been cast, the parts of the implement being in the position seen in Fig. 2, the dies are struck a smart blow, so as to swage or make the ball more solid. The die-carrier is then swung back on its pivot C, (see Fig. 3,) s0 as to withdraw the dies from the bullet-n1olds, and thus leaving a hole in the center of the bullet-shank extendingabout the whole length ofthe shank. The springs O allow the dies to yield slightly while being loosened and withdrawn from the center holes of the bullets.

1While the die-carrier is being swung back, as above described, the link G moves back, together with the arm. irl, and draws the plat-e F back with it, so as to cause the sharp edges l to move across the tops ot' the holes E, thereby cutting olf the supertlnons metal T and brining a smooth base of the bullet-shank.

The bullets can then be withdrawn from un-' LEWIS EVANS.
