RU2320950C2 - Signal rifle cartridge - Google Patents

Abstract

FIELD: applicable for sporting-smoothbore rifle shooting.

SUBSTANCE: the cartridge has a cartridge case, primer cap, ejection powder charge, wad-container consisting of an outer and inner cylinders. Wedge-shaped slots forming petals are made in the outer cylinder, and a star gauge of a pyrotechnical composition is placed in it. The outer cylinder consists of the interconnected upper and lower parts and connected to the inner cylinder by ribs in the form of a vertical grating serving as a shock absorber, ribs 0.6 to 1.0 mm grating serving as a shock absorber, ribs inner side, they secure in position the star gauge that is installed with a support on the upper surface of the vertical grating made with a taper angle of 28 to 32 degrees.

EFFECT: enhanced height of lifting of the signal star gauge, enhanced no-failure ignition of the star gauge and reduced recoil at a shot.

Description

The present invention relates to ammunition for sporting and hunting smoothbore guns, in particular to signal rifle cartridges, and can be used to send distress signals or alerts in extreme situations.

The closest technical solution to the prototype is the patent for the invention RU No. 2171444 from 07/27/2001

The cartridge consists of a sleeve, a fuse capsule, an expelling charge of smoky gunpowder, a cardboard and felt wad, and a star from a lighting pyrotechnic composition, on top of which a wad and a metal circle are installed.

The disadvantages of this technical solution are:

- partial failures of ignition of the sprocket (small contact surface of the sprocket during ignition);

- increased recoil when fired (hard wad);

- increased variation in the height of the sprocket due to the leakage of gases between the wad and the sleeve.

The objective of the present invention is to provide a signal rifle cartridge for firing sports and hunting rifles 12, 16, 20 calibers, providing the required lifting height of a burning signal star, reliability when ignited, and with a decrease in recoil when firing.

This problem is solved by the fact that the signal rifle cartridge containing a sleeve, an igniter capsule, expelling charge of gunpowder, a wad container consisting of an external and an internal cylinder, wherein wedge-shaped slots are formed in the external cylinder, forming petals, an asterisk of pyrotechnic composition is placed, the outer cylinder consists of upper and lower parts interconnected with each other and with the inner cylinder by ribs, in the form of a vertical lattice that acts as a shock absorber, ribs are made on the petals from the inside hundredth of 0.6-1.0 mm, holding a sprocket, which is installed with emphasis on the upper surface of a vertical lattice made conical with an angle of 28-32 degrees.

An annular protrusion is made from the outside of the lower part of the outer cylinder.

Figure 1 shows the design of the signal rifle cartridge, and figure 2 - the design of the wad container.

The cartridge consists (see Fig. 1) of a sleeve 1, in which a capsule - igniter 2 is installed. A hunting sleeve of 12, 16 or 20 calibers is used as a sleeve. In the encapsulated sleeve, the expelling charge of gunpowder 3 is poured and the wad container 4 is installed. A star from the pyrotechnic composition 5 is installed in the wad container 4. A tube of cartridge paper 6 is installed on top of the star and the sleeve is rolled onto the gasket 7, 8.

Wad-container (see figure 2), consisting of an external 9, 12 and an internal 10 cylinders.

The outer cylinder consists of an upper part 12 and a lower part 9, interconnected with the inner cylinder 10 by ribs 11 in the form of a vertical lattice, acting as a shock absorber. On the petals 14, ribs 13 with a height of 0.6-1.0 mm are made on the inner side, holding the sprocket, which is mounted with emphasis on the upper surface of the vertical grill 11, made conical with an angle of 28-32 degrees.

An annular protrusion 15 of 0.2-0.3 mm is made on the lower part of the outer cylinder 9.

The work of the cartridge is as follows. When triggered, the igniter capsule 2 (see Fig. 1) ignites the charge of gunpowder 3, which ignites the star from the pyrotechnic composition 5, and moves around the wad of the container 4 of the outer cylinder 9 with an annular protrusion 15, absorbing the power load-recoil when fired and further movement of the sprocket 5 with the wad-container 4. The pressure of the powder gases ensures the opening of the sleeve edge and the ejection of the wad-container with the star from the barrel of the gun, preventing it from “swinging”. When flying out of the gun, the wad container is braked by the oncoming air stream, and the burning star rises to a predetermined height, ensuring the creation of a signal. Burning a star at a height eliminates the danger of ignition of flammable objects on the ground.

Thus, the proposed signal cartridge with a wad-container, centering the sprocket, which allows to increase the surface of ignition, sealing from the flow of gases of the powder charge, absorbing the recoil during firing and providing a stable height, reliable operation of the signal.

Claims (2)

1. The signal rifle cartridge containing a sleeve, an igniter capsule, a charge of gunpowder, a wad-container consisting of an external and an internal cylinder, wherein wedge-shaped slots are made in the outer cylinder and form a petal, and a star made of pyrotechnic composition is placed, characterized in that the outer cylinder consists of upper and lower parts interconnected with each other and with the inner cylinder by ribs, in the form of a vertical lattice acting as a shock absorber, ribs 0.6-1.0 high are made on the petals on the inside mm, holding the sprocket, which is installed with emphasis on the upper surface of the vertical lattice, made conical with an angle of 28-32 °. 2. The cartridge according to claim 1, characterized in that an annular protrusion is made outside the lower part of the outer cylinder.
