1 Claim, 6 Drawing Figures CARTRIDGE This invention relates to cartridges primarily for use in target shooting.
The primary object of this invention is a light weight cartridge eliminating ricochetting and the necessity of heavy target backing.
Another object of this invention is an adaptable and variable weight head.
The above and other objects of this invention will become apparent to those skilled in the art after a consideration of a detailed description of preferred embodiments taken together with the accompanying drawing wherein:
FIG. 1 is a side elevational view of the cartridge;
FIG. 2 is a sectional view taken on the line 2-2 of FIG. 1;
FIG. 3 is a sectional view taken on line 33 of FIG.
FIG. 4 is a cross-sectional view of an embodiment where the head is secured to a conventional casing;
FIG. 5 is a cross-sectional view of the cartridge where the head is fixed to the rest of the casing forming the total cartridge; and
FIG. 6 is a cross-sectional view of an embodiment showing a shorter cartridge.
Referring in detail to the drawing, there is shown in FIGS. l3 a tube having a hollow rear portion 22 for holding the powder charge and a convex ring 24 extending from the inside surface of tube 20 adjacent the rear end thereof. Mating with ring 24 is a concave annular groove 26 within the cylindrical surface of a plug 28 extending from a flat cap 30. A detonation cap 32 is inserted in cap and plug 28 which is in turn locked against the rear end of tube 20 by means of mating ring 24 and groove 26. The front head 34 of tube 20 tapers to a rounded point and is solid with a leadinsert 36 embedded therein for determining the range of the bullet.
The velocity of the bullet of FIGS. 1-3 will give a range of approximately 75 yards and will be primarily for target shooting. The weight of lead insert 36 in head 34 can be molded during manufacture and determines the range of the bullet. Tube 20 can be made of different colored plastics of 5 suitable type and in competition, if the participants used a different color for the same target, it would be easy to identify which party hit the bullseye. This is because the projectile can be seen or located in the styrofoam directly behind the hole in the paper target. Styrofoam of course can be used in view of the short range and light weight of the bullet rather than the conventional steel backup plate behind the target. The bullet is made of one piece out of thin aluminum or plastic, and everything leaves the gun upon detonation except for cap 30.
FIG. 4 shows a slit 40 in the tip of a head 39 within which lead insert 36 of any desired weight may be manually inserted to determine the distance in knocking power of the bullet. Head 39 is removably secured at point 42 to a tube 44 and may, if desired, be separated from tube 44 and used in standard shells such as shown in FIG. 5. FIG. 5 shows a head 50 without slit 40 and secured to a standard casing 52.
The bullet can of course be of varying length and FIG. 6 illustrates a shorter version with a reduced length tube and a reduced length head 62 with a lead insert 64.
While preferred embodiments of this invention have been illustrated and described, it should be understood by those skilled in the art that many changes and modifications may be resorted to without departing from the spirit and scope of the invention. It should be noted that this invention is normally for use with small caliber hand guns or perhaps 22 caliber rifles. For larger caliber rifles or perhaps 45 caliber revolvers, it would be advisable to have reinforcing ribs running the length of the cartridge projection.
1. A cartridge, comprising a hollow tube, a lightweight bullet detachably secured to one end of said tube and extending outwardly therefrom, detonating means removably locked to the other end of said tube, said bullet having an open aperture in the forward end thereof, and a manually insertable variably selectable weight means positioned within said aperture for determining the range of the bullet.
