AMMUNITION-SHELL.

Application filed August 21, 1918. Serial No. 250,773.

To all whom it may Concern:

Be it known that I, JOSEPH DE CASE, a `subject of the Kingof Italy, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful ImprovementsY in Ammunition- Shells, of which the following is a specification.

This invention relates ,to ammunition shells or cartridges, and has for its object to provide a shell having certain advantages as will appear from the following description.

One object of the invention is to provide a shell with a charge of shot, and devices by means of which the shot will be permitted to scatter at a greater or lesser distance fromthe muzzle of the gun. With ordinary shells used in shot guns or heavier guns the shot when discharged travels in contact with the surface of the bore of the gun, which scores or erodes said surface. By means of the present invention the shot is confined in a casing until it reaches the muzzle of the gun after which the casing breaks or ruptures and the shot spreads or scatters. The invention embodies a powder case and a shot case connected together by means permitting them to be readily separated when the powder is exploded, said device consisting conveniently of a cord treated with a quick burning material, connecting the two cases, this cord being burned when the powder is exploded.

After the shot case is discharged from the muzzle of the gun it will separate and the shot will scatter, the time of the fracture of the shot case being toa certain eX- tent controlled in advance.

The invention will be found useful in shrapnel projectiles as well as in shells for various kinds of guns, and the cartridges can be loaded into machine gun belts and fed into automatic revolvers and machine guns as easily and rapidly as the standard cartridges now in use; and a further feature of the invention is that the shot will scatter without the employment of a second eX- losive charge in the shot case which may e made of paper or other light material, which will protect the bore of the gun at the time of discharge, but which will rupture after leaving the muzzle to permit the shot to scatter.

In the accompanying drawings, Figure 1 is a longitudinal section of one type of shell Specification of Letters Patent.

embodying the invention. Figs. 2 and 3 are sections on the line 2-2 and 3 3-of Fig. 1. Fig. 4 is a. longitudinal section of another type of shell. Fig. 5 is an end View of Fig. Ll. F ig. 6 is a detail of a small tube in the shot case, the purpose of which will be explained. Fig. 7 is a longitudinal section of another modification and Fig. 8 is a sectionon the line 8 8 thereof. Figs. 9 and 10 are similar views of another modification. Fig. 11 is a plan of one of the parts shown in Fig. 9.

Referring first to Figs. 1, 2 and 3, 6 is a powder casing and 7 the powder therein. 8 is a shot casing or cylinder, the barrel of which is made in two semi-circular parts joined with a lapped joint, as indicated at 8a. This is closed at the front end by a disk 8b and at the rear end by a cup-shaped base 12 made of rather stouter material and joined to the cylinder 8 at the line 8b. This base fits within the front end of the powder.

thence through the disk 8b, the shot chamber containing the shot 9, thence through circular grooves 13b in the front end Of the base 12, and thence rearwardly through holes in the base and through the powder chamber and through holes in lugs 14 at the rear end of said chamber. Where it extends through the passages in the base 12, the cord is knotted as indicated at 17 and the knots are engaged by set screws 13, one or more of which may be used. When the gun is fired, the cord l1 will be burned in the powder chamber, and the shot case as a whole will leave the muzzle of the gun and will remain intact as long as its

parts

8, 10 and 12 are held together by the cord, and the time of this operation will depend on the number of set screws 13 used. These set screws engage the knots and prevent any slip or release of the cord holding the parts together until the knots have been burned,

at which time the shot case will fall to will be released and the shot case, being made of light material, will break or fall to pieces and the shot will scatter. To delay this action the second or third set screws vare used and the cord will not b e released until the corresponding knots are reached and burned off, the cord being made of quickburning material as above stated. Accordingly the time of the scattering of the shot can be controlled to a certain extent.

In the form shown in Fig. 4 the parts are substantially the same as above described, with the following exceptions, although the cylinder 8 in this case is made in one piece instead of two, this form being intended more especially for small-arms.

The main di'erences''eferred to relate to the means for controlling the burstin of the shot case. The knots in the cor 11,

- which fastens the parts of the shot case together, instead of being engaged by set .screws are engaged or held in a corrugated tube 18 which is set in the base of the shot case, with the knots engaged by the corrugations, the timing of the release of the cord being controlled by the number of knots. If only the knot nearest the powder chamber is used, the shot case'will fall apart as soon as the knot is burned. If additional knots are used, the action will be delayed until they are all burned.

Figs. 7 to 11 are developments of the same i lea. In Fig. 7 the knot-engaging tube'18 is inclosed or telescoped in a sleeve 18a and set in the shot chamber between the cap and base walls thereof, the timing being controlled in a manner similar to that described with respect to Fig. 4.

In Fig. 9 a spiral tube 20 is used through which the cord passes, this tube being inclosed in a sleeve 19 set in the shot case. The length of the spiral tube 20 controls the time of release. If a short tube is used, the cord will soon burn and allow the shot ease to fall apart. If a longer tube is used, this action will be delayed accordingly.

The invention may be embodied in various other forms within the scope thereof and no limitation in this respect is employed in consequence of the particular forms shown.

It may be remarked that since the cord 1l, before tiring, not only holds the parts of the shot case together, but also holds the shot case joined to the powder case, the former will easily release when that part of the cord l1 in the powder case is burned; hence there is but little recoil, as the rear end of the shot 1(ase can be set in the powder case at an easy I claim:

1. A shell comprising a powder case, a shot case, and a combustible cord connecting said cases and located within the powder case.

2. A shell comprising a powder case, a shot case having a head and a cord extending from the head through the shot and powder cases and connected to the base of the latter.

Y 3. A shell comprising a powder case, a shot case made in sections, and a combustible connection between the powder case and the sections of the shot case.

4. A shell comprising a powder case, a shot case itting in the end thereof and consisting of several sections, and a combustible connection between the sections and the shot case.

5. A shell comprising a powder case, a shot case fitting in the end thereof and consisting of several sections, and a combustible connection between the sections and the shot case, said combustible connection being provided with means to control the time of release thereof.

G. A shell comprising a powder case, a shot case fitted thereto and having a separable head, and a cord extending from the head through the shot case and connected to the powder case, to hold the parts together, and adapted to be burned by the explosion of the powder.

7. A shell comprising a powder case, a shot case tted thereto, said shot case consisting of sections, a cord connecting said sections and provided with a series of knots and extending through the powder case for ignition by the powder, and means engagin more or less of the knots to vary the time o release of the cord, to permit the separation of the sections of the shot case.

In testimony whereof, I do ailix my signature in presence of two witnesses.
