CHARLES EDWARD SNEIDER, OF BALTIMORE, MARYLAND, ASSIGNQR OF ONE-HALF HIS RIGHT TO JOSIAS PENNINGTON, JR., 0F `SAME PLACE.

IMPROVEMENT IN SHOT-CARTRIDGES.

Specijcatonformz'ng part of Letters Patent No. 102,984, dated May 10, 1870.

'o all lwhom it may concern: i

Be it known that I, CHARLES EDWARD SNEIDER, of the city of Baltimore and State of Maryland, have invented certain new vand .useful Improvements in Shot-Cartridges, so that they may be fired from a non-chambered bore or barrel; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specification, in whieh- Figure 1 represents a perspective view of the shot-cartridge. Fig. 2 represents a section through the same. Fig. 3 represents a section through a portion ot' a gun-barrel, with the cartridge in section therein.

Shot-cartridges, as heretofore made, have been loaded in and tired from a chamber in the rear of the barrel, and the making of such chamber, which involves the making of a shoulder, so weakens the barrel at the point where it endures the greatest strain as to cause4 it to rupture, crack, and burst.

My invention consists in a shot-cartridge the shell or case of which is made of one piece, or without ashoulder, and partially cutthrou gh at the line where the portion containing the shot parts from or leaves the portion containing the charge ot' powder, by which means I can use and lire said cartridges from a nolichambered gun, and so preserve the strength ofthe barrel where it is most required; and my invention further consists in cutting a ap in the rear disk or head of the cartridgecase, and bending it inward to form a support t'or the tiring-pin, which avoids the necessity of an extra chamber or a pasteboard disk or bottom for securing the cap and pin, as heretofore.

To enable others skilled in the art to make and use my invention, I will proceed to de- .scribe the same with rel'erence to the drawings.

The cylinder or case a, I make of pasteboard, by preference, though it may be made of other material, in whole or in part, and this cylinder is united to a metallic flanged head, b, to form' the case.

A flap, c, is cut or punched in the metal fore or after being bent) with a hole for the ring-pin d to pass through and be supported in, said tiring-pin resting in a cap, e, in the cartridge-case. The opening in the head of the cartridge made by cutting. the flap and bending it inward is afterward closed by a paper or other diaphragm, suitably varnished to keep out moisture. 1

Making a support for the riug-pin out of a portion ofthe head of the cartridge avoids the use of a pasteboard bottom or a separate chamber for the firing-pin, as heretofore made. The cartridge-case so made is punched, creased, or partially cut at or about the line f, so that, when discharged or tired, the forward portion will leave the after portion and go with the shot, the case parting at this partial] y severed or weakened line j'.

When the cap and firing-pin are arranged, then the charge ot' powder g is .irst put in; then a wad, h,- on that the charge of shot t; then 'a disk or wad, j, on which latter the end of the case is bent over or crimped on, to hold the charge to the cartridge.

The bore of the gun need not be chambered for this cartridge, but is so made as to allow the cartridge to freely slide into the bore, or slightly, very slightly, tapered for that purpose.

The front ot the cartridge-case going out with the shot tends to concentrate the latter, or make close77 shooting, as it is termed.

Having thus fully described my invention, what I claim is- 1. Making the case or cylinder of a shot-car-A tridge of a single piece, partially severed, or so weakened in front of the powder-wad as to separate, when tired, at that point, and go out with the shot, and so obviate a chambered bore to the gun, substantially as described and represented.

2. In combination with a shot-cartridge, the iiap c, cut and made from the head of the cartridge-case, as a support for the tiring-pin, substantially as and for the purpose described.

CHARLES EDWARD SNEIDER.
