Abstract

FIELD: small arms. SUBSTANCE: cartridge feeding mechanism includes two tubular magazines each loaded with its own type of ammunitions, two separators coupled to mobile parts of weapon, carriage with change-over mechanism, position locating arm and thrust plate to overlap outlet duct of one of magazines and two bell-cranks placed transverse to magazines. One arms of bell-cranks can interact with thrust plate and the other ones enter grooves of proper magazines. With movement of mobile parts of weapon separators are moved aside and cartridges are fed from magazine not overlapped by thrust plate. After consumption of cartridges from one magazine from which they are fed, one arm of proper bell-crank will lower into through groove of magazine wall and second arm acts on thrust plate, turns it freeing duct of second magazine which automatically provides for continuance of feeding and shooting. EFFECT: improved reliability and shooting capabilities, simplified design. 2 cl, 4 dwg

Description

 The invention relates to small arms, namely to cartridge feeding devices, magazines for automatic and non-automatic hunting rifles.

Known weapons containing one barrel, a tubular magazine with a spring and a feeder [1]
The disadvantage of this weapon is the lack of choice of the type of ammunition immediately before the shot.

 Closest to the invention is a device [2] having a single barrel, a multi-charged tubular magazine and a translator with a cartridge cutter, which allows both single firing and self-loading.

 The device has a small weight, improved performance due to the rational placement of the translator, allows you to change the firing mode, but does not solve the problem of choosing the type of ammunition immediately before the shot.

 The objective of the invention is the selection of the type of ammunition for various purposes immediately before firing and automatically switching to the second store when the ammunition is used up in the first.

 For this, the cartridge feeding mechanism, comprising a tubular magazine and a cartridge cutter, is equipped with a second magazine with its cartridge and magazine selector, made in the form of a transverse magazine carriage with a switch, a position lock and a spring-loaded stop plate that overlaps the outlet channel of one of the magazines, and the cutters are connected with moving parts of the weapon and made with the possibility of overlapping the output channels of both stores.

 Two levers are fixed in the output channels with the possibility of rotation around the axis, one arm of which interacts with the thrust plate, and the second enters, respectively, in the through groove of the wall of its store, the second shoulder being spring-loaded to the axis of the store channel. The cutoffs and the thrust plate have a tapered inlet facing the loading direction, the lever spring is more powerful than the spring of the thrust plate.

 Each store is loaded with its own type of ammunition, and when the moving parts of the weapon are triggered, a cartridge comes from the store, which is not covered by a thrust plate, but after shooting one store, the second is automatically turned on and the shooting continues.

 In FIG. 1 shows a device from the outlet channels of the stores; in FIG. 2 same, top view; in FIG. 3, section AA in FIG. 1 (magazine with cartridges); in FIG. 4, section AA in FIG. 1 (magazine without cartridges).

 The device contains two magazines 1 and 2 with through grooves along the axis a and b, the output channels of which are blocked by cut-off cartridges 3 located on the axis 4 and interacting through the rod 5 with the moving parts of the weapon 6. Each cut-off has its own spring 7 and a bevel for loading in . Across the output channels, the carriage 9 is moved in the guides 8, having a switch 10, equipped with a position lock 11 and bearing a thrust plate 12 mounted on the axis 13. The thrust plate has a bevel g for loading cartridges, its own spring 14 and it closes the outlet channel of one of the stores 1 or 2. The device is equipped with two two-arm levers 15 and 16, each mounted in its groove a or b on the fixed axes 17 and 18, with the shoulders d and e of the levers 15 and 16 interacting with the thrust plate 12, and the second shoulders g and s are included grooves a, b stores 1 and 2. Two shoulders levers 15, 16 have their own springs 19 and 20, which tend to drown the shoulders g and s in the grooves a and b of stores 1 and 2. In stores 1 and 2, a spring 21 and a feeder 22 of cartridges are placed and there may be cartridges 23 .

 The mechanism works as follows.

 The shooter randomly charges each magazine 1 or 2 with the same type of cartridges 23, while the cartridge, acting on the bevel in the cutter 3 and when the magazine is blocked on the bevel g of the thrust plate 12, pushes them to the sides, pushes the cartridge feeder 22, compresses the spring 21, while this shoulders w or z are brought out of the stores outside. From the reverse bias, the cartridge 23 is held by the cutter 3, which returns to its original position when the cartridge 23 fully enters the magazine 1 or 2.

 Before the shot, the shooter selects the magazine from which he is going to shoot, acting on the switch 10, while the carriage 9 moves until the latch 11 is activated and the thrust plate 12 blocks the unnecessary magazine. Next, the shooter moves the moving parts of the weapon 6, while the rod 5 briefly acts on both parts of the cutter 3 and takes them to the side, while the extreme cartridge 23 is pushed out of the unopened magazine under the action of the spring 21 to fire.

 The retraction time towards the cutter 3 should be calculated so that only one cartridge 23 could exit the magazine 1 or 2 in one move of the moving parts of the weapon 6.

 If it is necessary to fire a shot from another magazine, the shooter acts on the switch 10, puts the carriage 9 in a different position, the operation of the cartridge feeding device 23 from another magazine is similar.

 After the ammunition is consumed in the store from which the shooting is currently taking place, the shoulders w or w under the action of their springs 19 or 20 will be able to enter the grooves a or b of empty magazines 1 or 2, while the two-arm levers 15 or 16 will rotate around their axes 17 or 18 and with their shoulders d or e act on the thrust plate 12, rotate it around the axis 13, while the thrust plate 12 opens the blocked channel of the second magazine 1 or 2 with cartridges and the shooting from the second magazine, however with other types of cartridges, continues uninterrupted.

 This device allows the shooter to choose the type of ammunition immediately before the shot and allows you to shoot the entire ammunition without additional manipulations with the weapon, which increases the practical rate of fire.
