UNITED STATES PATENT OFFICE.

MYRON OOLONEY, or NEW HAVEN, CONNECTICUT, ASSIGNOR To JAMES HENRY MCLEAN, or sT. LOUIS, MISSOURI.

CARTRIDGE.

SPECIFICATION forming part of Letters Patent No. 225,464, dated March 16, 1880. Application filed February 10, 1879.

To all whom it may concern:

Be it known that I, MYRON GoLoNEY, of the city and county of New Haven, in the State of Connecticut, have invented a certain new and useful Improvement in Cartridges, of which the following is a specification.

My cartridge consists of three members, to wit: a cylindrical case for the powder, preferably grooved circumferentially at its rear end; a projectile formed with conical front and rear ends, a cylindrical center portion and a stem or tail projecting backward in the line of its axis; and a uniting plug or sabot, preferably of wood, reamed out in front to receive the conical rear of the ball, and perforated in its axis to receive the stem thereof, and at back formed with a rabbet to fit within the front of the cartridge-shell.

In order that my invention may be fully understood, I will proceed to describe it with reference to theaccompa-nying drawings, in which- Figure 1 is a side elevation of the parts of the cartridge detached. Fig.2 is a longitudinal section of the complete cartridge.

A represents a cylindrical case, of paper, sheet metal, or other material, intended for the reception of the powder, and having a circumferential groove, a, at its rear end, to adapt the cartridge to be passed laterally between suitable jaws in the breech of the arm, which jaws, engaging in said groove, will hold the cartridge firmly against the stroke of the firing-pin. The base of shell A is also preferably formed with a customary nipple or fulmi nate-recess, a, for center-fire; but, if preferred, the invention may be embodied in a rim-fire cartridge.

The projectile O is formed with a conical front and rear and a cylindrical center part, as shown, and from the apex of its conical rear end extends a stem, 0, in line with the axis.

The central uniting plug or sabot, B, is formed in front with a cavity to fit the rear end of the )rojectile C, and is bored in line with its axis to receive the stem 0, the periphery of the plug or sabot B being precisely flush with that of the projectile O. p

The rear of the plug or sabot is formed with a groove or rabbet, b, to adapt it to fit within the front of the powder-case A, within which it is securely glued when said case is tilled.

The plug or sabot B maybe made of paper, but preferably of wood. The powder-case A is of paper or sheet metal or other material.

The projectile (3 may be of any metal preferred.

I am aware that projectiles have before been made with a cylindrical central part and conical front and rear; also, that projectiles of different forms have been made with a rearwardly-projecting central stem.

Special advantages result from my mode of forming the ball with a cylindrical center to guide it accurately through the bore, and combining therewith the conical front and rear, to lessen atmospheric resistance, and the rearwardly-projecting stem, to prevent deflection. Further advantage results from combining with a ball, G, shaped as specified, a hand or sabot, B, of the form shown, fitting the conical back of the ball, extending the cylindrical outer surface to the necessary length, attached to the ball by the stem and serving for the attachment of the cartridge shell or case.

Having thus described my invention, the

following is what'I claim as new and desire to secure by Letters Patent:

1. The projectile O, constructed as herein described, with conical front and rear, cylindrical center, and a rearwardlyprojecting stem, 0.

2. The combin ation of the projectile G,formed with a cylindrical center, conical ends, and a rearwardly-projecting stem, and the band or sabot 13, formed with a cylindrical periphery flush with that of the hall, a shoulder or rabbet for the attachment of the case A, and a central aperture to receive the stem 0, by which it is attached to the ball.

MYRON OOLONEY.
