Description

The subject of the present invention is an automatic sport hunting rifle.

The device of the proposed rifle is shown in the attached drawings, where in FIG. 1 and 2 show longitudinal sections of the rifle; FIG. 3 shows a section along the line AB in FIG. 2, in FIG. 4 and 5 longitudinal sections of the shutter, in FIG. b-view of the closure in front and in fig. 7 detail of the articulation of the main elements of the rifle.

The shutter device is as follows. A cylindrical stopper li with a pair of under-barrel shears F and F (Figs. 4 and 5) is integral with the stop O through which the axial rod L of the return spring 1 controls the action of the shutter. When the gas pressure to the bottom of the liner, the valve retracts and squeezes the return spring with its support.

The arrow on the sleeve with extractor E (Fig. 3 and 4) and stops S (Fig. 4) is removed from the chamber and moves with the shutter until the rod a hits the end of the projection I (Fig. 1 and 2). At this point, the liner receives a punch and is thrown through a window (not shown in the drawing) in the box; during the reverse movement of the bolt under the action of the force of the return spring, the protrusion protrusion P encounters the stop W and cocks the drummer into the fighting position. When the trigger is pulled down, the support W is lowered and the hammer gets back into place with a force of the mainspring and strikes the cartridge piston. Dyr la Zh and Zh (Fig. 5), after a shot was fired, the firing pin was somewhat back, for the sake of greater security, if necessary, to remove the whole cartridge from the rifle. The forcedness of the correct direction of the striker is guaranteed by the sliders 5 and 3 (Fig. 3) extending into the corresponding grooves. The axial rod for the spring cocking the drummer is the central rod, which is integral with the protrusion protrusion P.

After removing the handle T and unscrewing the bottom W of the shutter (Figs. 5 and 6), the entire shutter disintegrates into its component parts, the complete disassembly of which is already self-evident from the drawing. The dimple is screwed into the socket and this achieves both the ease of adjusting the degree of its release for impact and the convenience of changing it in the event of a breakdown or wear. In the same way, the length of the path of the rod of the protrusion l is changed, and the force of the impact can be adjusted when the liner is thrown out.

The rifle sights consist of: 1) low and thin at the top, but broad at the base of the front sight 8 and 2) the sighting frame with a movable buckle 9, I have a small slit inclined to the eye with a small slot with a round bottom. In addition, there is a folding (liftable) shield diopter (Fig. 1-2), also inclined to the eye, but so that the upper conical opening, with the raised shield, parallel to the horizon. The inclination of the shield on the linkage of the aiming frame and the inclination of the thyroid under the diopter to the eye are made, according to which these planes are always in the shade, and not as mirrors reflecting the rays falling on them. Sometimes shooting conditions on hunting (on currents, on birds, on beasts, etc.) require limited field of view (especially in bright light) and accuracy of aiming, which can be sufficiently achieved with these instruments, even without installing optical tubes and t. n.

The front sight is inserted into the raised base in order to: 1) give it a good base and the ability to precisely adjust, 2) protect it from damage, and 3) be able to attach another special clip on the pedestal with protruding vertical side panels. The latter device may sometimes be necessary and useful in shooting conditions with bright side lighting.

The rifle is equipped with a magazine that holds a single ferrule with only three rounds, the fourth

the cartridge is inserted directly into the barrel. The clip is removed from the socket in the following way: the latch Q is retracted (Fig. 2) and the clip is removed by gripping the edges of the clip through the recesses in the box.

After discarding the last sleeve, the shutter remains open. This is achieved in this way: probe L) (Figs. 1 and 2) rests normally on the cartridge, but as soon as the cartridges are not in the holder, the probe slightly tilts inside the holder, its 5G protrusion rises and the projections G (Fig. 2) inlet t in the notches in th shutter. To put the bolt in place, you must either insert a new clip with cartridges and then the U probe will fall into place and the bolt will send the cartridge and close, or else you need to press the rod head b. (Fig. 2) and then the shutter will also be in place, but without delivery of the cartridge, if it was not in the holder. In addition, the rifle is equipped with a fuse 9, closing its emphasis trigger dog 7.

In the cavity of the butt is placed a spring coil (like a tape measure) with a belt wound around it. If necessary, use a belt, it is pulled over the shackle 6 and the latter is put on hook b (Fig. 1) on the shank.

In cases where the belt can be a hindrance (in the gap, in the dash, etc.), it is wound onto the coil by the force of an internal spring placed in the inside of the coil (dotted circle in Fig. 1).

The rifle is disassembled using the upper key 1 /, by moving it to the side (to the right) at an angle; in this position, the key slides back the slider a (Fig. 7) and the bolts b b. After that, it is possible to rotate the two elements of the rifle barrel, the forearm and the box with the bolt, on the one hand - the butt of the pad and the trigger mechanism,

on the other hand, near the axial screw Z (Fig. 1.2).

If necessary, completely disassemble the rifle for the purpose of care or to change the barrel, do the following: remove the forearm, to do this, press the head towards {FIG. 1), and take the handguard down a little and then forward. Taking the barrel out of the box is made by turning it 90 °, then the protrusions gig (Fig. 2) become opposite to the corresponding slots in the box and the barrel is removed. The shutter is removed as follows: the hollow rod is unscrewed. (Fig. 2), serving as the axis for the main spring; the latter falls out. The screw is then unscrewed in the bolt (Fig. 6) to allow the shutter handle T to unfold, after which the latter slides freely out of the box to the outside.

The subject of the patent.

1. An automatic sporting and hunting rifle with a replaceable barrel, consisting of two parts connected by a locking clutch, which is characterized with a cumulative use: a) - rifle bar g F, F with a jumper, sliding along

rod L, in order to compress the return spring 1 controlling the gate; b) a cylindrical drummer 2 with sectoral guides carrying the stop P, engaged with the platoon W, the spiral spring pressed upward and coupled with the trigger dog 7, which drummer is equipped with two spring stops F, F serving to conceal the striker for the front cut of the bolt ; c) an extractor E and a movable reflector S (Fig. 4), the stem of which is assigned to strike the end of the rollback on the protrusion, in order to eject the boom sleeve; d) the tp fuse closing the triggering dog 7 with its stop and the U-K delay releasing the sliders when turning (7, (7 that engage with the ledges of the t f f, F of the bolt when the last cartridge is exhausted from).

2. The use of the sighting device, consisting of the muschka 8, the aiming frame with the movable collar 9 and the hinged diopter g, described in paragraph 1 of the rifle, and the inclination of the flaps is directed towards the eye of the arrow for darkening.
