SU195928A1 - SELF-DRIVING HUNTERS CARABINS - Google Patents

Description

The known systems of self-charging hunting carbines for a 5.6 mm caliber of side fire are performed, as a rule, with locking according to the principle of the free-roll recoil energy. However, "earlier shutter opening and the release of gases and unburned powder particles, injuring the shooter’s face and eyes, misfires due to contamination of cartridges, etc., reduce the operational and combat qualities of weapons, and the known methods of reducing rubbing surfaces and folding of ice do not fully provide stable operation of automation.

The essence of the proposed invention is that the assembled barrel with the box is connected to the bed on a free landing, and the stop fixed in the bed fixes the barrel from longitudinal displacement when fired. This provides increased accuracy of bo, dynamic stability of the barrel when fired and reliable operation of automation.

In order to reliably protect the shooter’s face from unburned particles of gunpowder and gases, the front end of the bolt is designed as a reflector visor that interacts with the protrusion on the stump and removes ejected gases and unburned powder particles ahead.

protrusions with transverse slots, and in the walls of the box and the box there are additional grooves.

FIG. 1 schematically shows the proposed carbine, side view: in FIG. 2 is the same longitudinal-vertical section: in FIG. 3 shows a shutter with protrusions and grooves for cleaning and collecting the accumulated debris, dirt and ice: in FIG. 4 - visor-detachment device at the end of the gate: in FIG. 5 - barrel box.

The hunting self-locking carbine consists of the barrel /, receiver, bolt, trigger mechanism, magazine and bed. The barrel is pressed into the box 2. The box is cylindrical, has grooves A for moving the lugs of the bolt, B for trigger 3, C for magazine 4, D for reflecting the sleeve and D for removing accumulated dirt and dust t through the groove in the box 5, which coincides with the groove D in the box.

The barrel assembly with the box is fixed in the box by means of the stop 6 of the barrel.

The shutter consists of a skeleton 7, a combat larva 8, a drummer 9 with a spring 10, a clamp of a combat larva 11 and a retaining ring 12.

At the front end of the skeleton 7 of the gate there is a visor-reflector L for retraction of gases and unburned powder particles after the shot. In addition, longitudinal protrusions AND with transverse grooves L are made for collecting dust, dirt and splitting of ice on the body of the gate.

The trigger mechanism consists of a base 13, a trigger 5, a sear 14 with a spring 15, a combat spring 16, a safety lock 17, a trigger hook 18 with a spring 19, and a magazine latch 20 with a spring 21.

Subject invention

Claims (3)

1. A self-mounted hunting carbine containing a barrel with a box, firing mechanism, shutter, sighting devices, a buffer, a magazine and a bed, characterized in that, in order to increase the accuracy of the bo, dynamic stability of the barrel when fired and ensure reliable operation of the automation, the assembled barrel with the box is connected to the bed on a free landing, and the stop burst in the box fixes the barrel from longitudinal displacement when fired. 2. Karabin under item 1, characterized in that, in order to protect the face of the shooter from unburned particles of gunpowder and gases, the front end of the gate is made in the form of a visor-reflector, interacting with a protrusion on the stump of the stem and leading forward ejected gases and unburned particles of gunpowder. 3.Karabin on PP. 1 and 2, characterized in that, in order to cleave ice crusts and collect debris, dirt, dust and remove them from the carabiner during firing, longitudinal projections with transverse grooves are made on the bolt body, and additional walls are made in the walls of the box and bed grooves. fw i Y ////////// i /// ////////////// rig.and
