IMPROVEMENT IN CARTRIDGES POE FIRE-ARMS.

Specification fomag'part of Letters Patent 10121353, dated Augzist 24, 1858.

To all when! when concern:

Be it known that no, ltnwnv GoMEz and -WILL1AM MILLS, of the city and State of New York, have in vented, made, and applied to use, certain new and useful Improvements in (Jartridges for Fire-Arms, Cannons, and other explosive material contained in cases of explosive material, as well as non-explosive pa-. per, 85c; and cartridges have also been formed of explosive paper or similar material. Our invention, therefore, does not relate to either of the ioregoing devices, but consists in a means for distributing the force of an explosive compound over a sni'ficient extent of surface to prevent the arm exploding Our invention also relates to a means for removing,

the paper or case of the cartridge from the barrel of the fire-arm. y

In Letters Patent granted to us on the 15th day of Sew-ember, 1857, a composition is set forth as especially adapted to the manufac ture of trains and safety-fuse; but this, if applied in the same manner as gunpowder in cartridges, is found to be so sudden in its explosion and so concentrated in its action as to be dangerous and liable to burst the fire-arm. The same may be said of fnlminate of mercury and other compounds. To avoid this concentrated action of the said explosive ma terials we distribute the same over a larger extent of surface, and thereby remove all liability to injure the piece, by the use of alternate layers of explosive material and paper, or equivalent non-explosive substance; and to remove the said paper or other material and prevent its clogging the piece, we make use of a winding of string attached to the base of the ball, which draws out the said paper and olther refuse matter, leaving the gun'entirely 0 can.

' at the base of-the ball.

In the drawing, a is the ball, of an elongated, or conical shape; I) is a paper or similar case, one end of which is attached by the stringc to the base of the ball. (1 is the explosive material in layers, with paper or equivalent material intervening, which is t'd be inserted within the case b, and then the string 0 is wound around the cartridge, as seen in Fig..

1, the ends of the string being tied together In cases where thcoxplosive compound can be dissolved or made into the form of a paint, as is the case with our said patented compound, we prefer-to lay the same onto sheets of paper with a paint-brush, thencut said sheets up into strips and roll the same up as seen in Fig. 3; and where paper is used for the case b, we prefer that the string 0 be attached to the end next the ball by turningthe paper over the string and g unnning or pastingthe same.

This cartrid e when in use has the followin g peculiar properties: The in tervcniug paper forms a filling that causes the given amount of explosive material to occupy more space, and consequently lessen the sudden action of the explosive compound. on the barrel. -The paper also, being sli g'htl y elastic, aids, in relieviug the barrel, and also aids in making a tight joint with the breech-piece in breech-loading guns. Any smoke or soilagc from the explosive. material is principally retained within the paper, thus'lveeping the gun clean.

The winding of string; 0, or its equivalent, draws out the paper or refuse matter, leaving the gun clean for another cartridge. "he winding of string; prevents the paper or other material becoming embedded in the grooves of rifled barrels.

When said cartridge is greased, or similarly prepared, it is preferable on account of keeping the barrel in better order, and also preventing the string or casing beeoming ignited by the exph'ision.

' \Ve do not claim cartridges formed of explosive paper or other material, and we do not limit ourselves to any pa rticular explosive compound made use of in our cartridge; but

What we claim as our invention, and desire to secure by Letters Patent, is- 1. The manner herein specified of forming cartridges for fire-arms, and other purposes.
