IMPRovED'BULLET-MOLD.

Specification forming part `of Letters Patent No. 12,774, dated May 1,1855.

` To a/ZZ whom t may concern:

. Saline.

Be it known that I, WILLIAM ASHTON. of Middletown, in the county of Middlesex and State of Connecticut, have invented a new and Improved Bullet-Mold for Casting Hollow or MinieJ Bullets; and I do hereby `declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making part of this specification, in which Figure l is a longitudinal section of my improvement. Fig. 2 is a plan or top view of Similar letters of reference indicate corresponding parts in the two figures.

The nature of my invention consists in forming the mold with a movable core, arranged as will be presently `shown and described, whereby hollow or Mini bullets may be cast y with the greatest facility and in a perfect Inanwith a shank or handle, C, to the under surface of which a thin strip of metal, D, is attached by a pivot, c, so-that said strip D may turn thereon. i ,A

To the outer end of the strip D there is attached a conical projection, E, which corresponds in size to the desired opening or cavity Vof the bullets, and around the lower end of the conical projection upon the strip D there is a circular flange, d, which iits within the lower end of the cavity a. The strip D is allowed some play upon the pivot c.

On the upper end of the piece of metal B there isattached by a pivot, e, a metal strip, F, which has fa `circular aperture, f, made through its end directly over the opening b. The aperture f is beveled or countersunk, so

as to form a cutting-edge at its lower part. Thestrip Fis turned so that the aperture f is brought directly over the opening '11, and the projection E is placed within the conical aperture a. The meltedr lead islthen poured through the aperture f and openingjntb the e conical aperture a till it is filled. f' The strip F is then turned upon the pivot e,..an'd the lower edge of the aperture f wilLcut off the superfluous lead above the upper surface of the piece of metal or mold c. 'r-The projection I E is then Withdrawn from the aperture@ by depressing the end of the strip D J-.it being sufficiently elastic for that purpose, the bullet being on the projection; or if the bullet remains within the aperture a it is forced therefrom by jarring the mold. n

The above improvement is extremely simple, and perfect bullets may be cast with rapidity. As the melted lead is poured into the aperture a, the air will escape at the lower part of the aperture, for the iiange d lits only close Jenough to prevent the escape of the lead and not the air. The bullets, therefore, will be perf fectly cast. i

The molds of ordinary construction open longitudinally or lengthwise of the aperture, a, and have a permanent or immovable core. No provision is made for the escape of. air, and consequently, unless the lead is poured into the mold cautiously, ther/bullets will be cast of irregular form, technically termed screwsi77 What I claim as new, and desire to secure by Letters Patent, ise Constructing the mold as herein shown and described-viz., having a conical aperture, a, made in a piece of metal, and having a projectiou or core, E, and flange d attached toa metal strip, D, which is secured to the shank or handle C of the mold by a pivot, e, so that said projection or core may be inserted in and withdrawn from the aperture c, as hereinv shown anddescribed.
