EDWARD P. FOLLETT, OF CHICAGO, ILLINOIS.

SHOT-CARTRIDGE.

Application filed May '7. 1909.

Specification of Letters Patent.

Patented Nov. 1, 1914).

Serial No. 494,668.

To all whom it may concern:

Be it known that I, Eowann P. Fonnn'r'r, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Shot-Cartridges, of which the following is a specification.

The object of my invention is to provide a shot cartridge in which a separate case is secured containing the shot; that, when the cartridge is fired, leaves the shell, holds the shot inclosed to the distance at which it is designed to have the shot leave the case and scatters; a case which with its charge of shot can be placed in the metallic shell of shot and rifle cartridge, which after the fixed charge or bullet has been fired can be reloaded with powder and wads and the case of shotwhich I call a concentrator be inserted and fired from a gun or rifle; the concentrator being adapted to release the shot and scatter at the particular distance desired.

The manner in which I accomplish my object is described in the following specification and illustrated in the accompanying drawings in which:

Figure 1 is a longitudinal section of the shot cartridge containing the concentrator. Fig. 2 is a crosssection on the line 22 Fig. 1. Fig. 3 is a sectional view of a rifle shell with the concentrator inserted. Fig. l is one end of the concentrator shown in Fig. 3. Fig. 5 is a section on the line Fig. 3 of the concentrator.

In the drawings A indicates the shell of the shot and the rifle cartridges.

B indicates the concentrator as a whole as shown in the several figures.

0 is the cylindrical part of the concentrator which is made of paper greased to move freely in gun or rifle barrel. When the concentrator is made to be fixed in a shot cartridge as shown in Fig. 1 one end of the part C is closed by a metal cap D which is folded and rolled on one end of the cylinder as shown at D Fig. 5. The other end of this cylinder is closed by a head E made of paper having air holes E When the concentrator is so formed and partly filled with shot and is inserted with the cap D against the wads F the end of the shell A is then crimped inward against the head E thereby completing the shot cartridge as shown in Fig.1. When the concentrator in-epared for use in a metallic shot or rlfle cartridge shell as shown 111 Fig. 3 a fixed metal head G is substituted for the paper head E. This head G has air holes G and is folded upon the end of the cylinder and rolled down thereon after the shot is inserted as shown in Fig. 5, thus both ends of the cylinder are secured and the concentrator is ready for insertion in the metallic shell as shown in Fig. 3. The rolled edges I) of the cap D and head G together with the edges of the cylinder C are pressed below the diameter of the main part of the cylinder as shown in Fig. 5 and are thereby prevented from contact with the interior of a straight or rifled choked bore barrel. This construction also permits the cylinder 0 to enter the grooves of a rifle barrel. The holes E and G in the heads of the concentrator are adapted in number to the particular air pressure desired in the concentrator after it leaves the muzzle of a gun or rifle.

The air entering the concentrator through. the holes in the head operates as follows: hen the cartridge is' fired the shot is impelled against the cap D and thereby creates the air space between the shot H and heads E and G as shown in Figs. 1 and As the concentrator leaves the barrel the air enters and gathers pressure at the cap and the shot which moving forward by their weight and by pressure of the air and thereby changes the air space from the front to the rear of the cylinder. This change of location of the air space produces results similar to that of feathers on an arrow in keeping the concentrator from turning over. and at the particular distance determined by the construction and of the concentrator the air pressure in the cylinder retards its flight the head and shot being thereby released therefrom. When the concentrator is used in a metallic shot or rifle shell the head. being secured to the cylinder, and the movement of the shot and action of the air being the same, the release of the shot is effected by the bursting of the cylinder at a distance determined by the quantity of air admitted through the head and the thickness of the paper of which the cylinder is made. The pressure of the body of the cylinder G into the rifle grooves gives the concentrator the same rotary movement as a rifle ball, and

together with the rear air space insures a directness and distance in the firing of shot not otherwise obtained.

What I claim and desire to secure by Letters Patent is:

1. The combination with a cartridge shell; of a shot concentrator inscrtible therein, said concentrator consisting of a cylindrical body and ends adapted to close said cylinder, one of said ends nearest the open end of said cartridge having a plurality of perforations intermediate of the center and its rim, and a charge of shot partly filling said concentrator as described.

2. The combination with a cartridge shell; of a shot concentrator insertible therein, said concentrator consisting of a cylindrical body and abutting ends, said ends being adapted to close said cylinder, one of said ends nearest the open end of said cartridge having a plurality of perforations, and a charge of shot partly filling said concentrator, as described.

3. The combination with a cartridge shell; of a shot concentrator inclosable therein, consisting of a cylindrical body and ends adapted to close said cylinder, one of said ends nearest the charge in said cartridge being fixed to and closing said cylinder, the other end being adapted to abutagainst the other end of said cylinder and having a plurality of apertures, and a charge of shot. partly filling said cylinder as described.

4. The combination With a cartridge shell;

of a shot concentrator scclncd therein, said concentrator consisting of a cylindrical. body having one fixed end and another end adapted to abut against the opposite end, said abutting end being nearest the open end of said cartridge, and having a plurality of perforations, the diameter of said ends being less than the diameter of the central part of said cylindrical body, and a charge of shot partly filling said concentrator as described.

5. The combination With a cartridge shell; of a shot concentrator insertible therein, said concentrator consisting-of a cylindrical body having fixed ends, one of said ends having a plurality of perforations and the diameter of the central part of said body being adapted to prevent the ends from contact with the barrel of a gun, and a charge of shotpartly filling said concentrator. i

6. The combination With a cartridge shell; of a shot concentrator insertible in said shell, and containing a charge of shot, said concentrator consisting of a cylindrical body, ends fixed thereon, one of said ends having a plurality of perforations therein, and an air space in said concentrator whereby the air entering said body through said perforated end is adapted to discharge said shot from said concentrator.
