Description

[Detailed description of the invention] The three-dimensional size of the unreadable gun is about the same as that of a former folding shotgun, and from a front view, it is about the same height as the breech of a No. 12 caliber double-barreled gun (see Figure 8). ). In terms of plan view, the width of the nozzle of the No. 12 horizontal double gun is about the same as the width of the nozzle of the main gun (see the nozzle 5 in Figure 3). With this volume, as shown in Figure 10, there are 2 shotguns in the magazine, 3 shots in the rifle, and 1 shot in each chamber.
You will be able to fire a total of 4 2-ifle cartridges and 3 shotgun cartridges in succession. The main barrel is a rifle barrel 31 and a shot barrel 80 that are horizontally connected, and a eave 3 that receives and leads the cartridge at the tail of the barrel.
0, and in order to balance the thicknesses of the rifle barrel 31 and the shot barrel 80, a thin vibe 71 having the same thickness as the shot barrel 80 is covered. By moving this horizontal integrated gun barrel 3 back and forth, it acts both as a gun barrel and as a bolt. Fifth
As shown in the figure, the grooves 72 dug on both the left and right sides of the gun barrel 3 insert the protrusion 73 of the engine part 6 in a sliding state, and the gun barrel 3 and the engine part 6
Assemble. When the upper connecting stages at the bottom of the gun barrel 3 are set at 93 for the first stage, 89 for the second stage, and 90 for the third stage, when they are brought into close contact with the breech of the gun 13 and the head of the engine section 6 shown in FIGS. 7 and 8, The stopper 12 is raised and closed by the action of the spring 75. The safety device 2 shown in FIG. 6 is distinguished by fitting the spring shaft 19 of the safety device 2 into three appropriately spaced recesses bored in the engine section 6. If you pull safety device 2 to the front, it will look like the IE6 diagram.

(Since the hook 76 and the hook fitting 21 engage with each other, the plug 12
does not move, and accordingly, the leading platform 5 also does not move, and the fourth iron 4 does not move when the part 78 of the fourth iron 4 touches the part 77 of the safety gear 2. (2) When the safety device 2 is placed in the intermediate position, the hook 76 and the hook fitting 21 are disengaged, and the stopper 12 and the tip block 5 move, and by moving it forward, the rear end 790 of the tip fitting 9 moves. @1
Raise and remove 2, and barrel 3 begins to move forward. At that time, the protrusion 25 on the part 16 pushes the 4-iron protrusion 26 down to the inclined surface of the protrusion 25, resulting in 1 iron 4'kfi! i! Set. The safety device 2 at this intermediate position is in contact with the 4th iron 4, and the 4th iron does not move. The gun barrel 3 moves forward and only the fired blank cartridges are repelled by the push rods 49 and 41. When the safety device 2 is in the intermediate and forward position, the barrel 3 can freely move back and forth.

0) When the safety device 2 is moved forward, the 4 irons 4 will be released from the fixed position. Safety device 2 has an effect similar to α) (2) (s) 8.

The part 9 in the front stand in Fig. 4 is the mounting stand 9 installed under the barrel 3.
1 is tightened with a screw 11, and the part 9 has a long hole that can freely move forward with respect to the gun barrel by about 1@, and a return spring shaft 10 is attached to it so that it can be returned to its original position.

FIG. 7 37 shows a shot cartridge cartridge chamber, 83 is a leading groove portion of the breech eave 30, 36 is a rifle cartridge chamber, and 84 is its lead portion. 35 is a notch made so that the cartridge stopper 53 in the magazine is not obstructed by the breech of the gun barrel.

Figure 8 is a front view of the engine section.

Dry 3B and 39 catch the cartridges and place them so that they don't run away. The push rod 42.43 is inside the circle 85.86, and the bottom part) comes out at the 1st position, and pushes up the tip of the cartridge and leads the lead fullj.
Make it touch 83 and 84. 44.45 is the striking hole. 40° 41 is a push rod that ejects only the empty packets.

The circle 85.86 is large enough to fit the bottom of the cartridge, and in order to prevent explosion and securely hold the cartridge, 4 holes are drilled into it. etc., below the engine head surface. The protruding rail 73 has a groove 72
to go into. 28 is a push angle bar, 46Fil & 12 center bin, screw 47 is its set screw, and 74 is a12 clasp.

FIG. 9 is a sectional view taken along the AB cut line of the engine section 6.
39 is a blank drawer, 48 is a striking core, and 41.49, 40, and 81 are extrusion rods. The pushing rod is pushed diagonally from behind by the spring shafts 82 and 50, as shown in Figure O (partially pressed). 49. 41 is falling. It is.

4 When the iron 4 is pulled and the hammer 51 falls, the barrel 3 moves forward only when it becomes an empty cartridge, and when it comes out of the chamber, it is ejected to the picture side by the extruder.

In order to reach the state of 81.40, it is pushed by the bottom of the cartridge that has come up, and the hook of 81 hooks IiK on the engine part by the lateral force of the return spring shaft 82.

The cartridge lift stopper 53 shown in FIG. 10 is a spring 54 that is hinge-likely connected to the bottle 55 and has enough elasticity to hold the cartridge in place when the tip of the cartridge enters the chamber. In the case of a shot cartridge, it is necessary to raise the bottom of the cartridge using the inclined surface of the metal fitting 64 that is pressed by the spring 65 in FIG. A cartridge pusher in the magazine uses an arm 67 and a spring 69 to push up the cartridges. Part 68 pushes the arm 67 of the cartridge lifter down into the bottom of the magazine when loading a cartridge into the magazine, facilitating loading into the magazine. To do this, pull out the gun barrel 3 all the way and stop the stopper 12 in contact with the upper (second stage) 89 at the rear of the gun barrel 3, as shown in FIG.

If you continue to pull the barrel 3 forward and pull the part 15 toward you, the 1tk12 will enter the third stage 90 at the rear and move the barrel 3 forward.
stops.

At this time, an uneven groove is created in the lower part of the gun barrel (indicated by dotted line 70) into which the component 68 slides. The part 68 is pushed down by the protrusion of the dotted line 70, and therefore the arm 67 is lowered, making it easier to load the cartridge.

Fig. 11 Raising the hook hammer 51 so that it engages the hook 60 of 51 and the hook of 4 iron 4 is done by the pusher bar 28 pushed by the breech. A point centered on the center pin 87 of the rear end part 52 of the pushing square rod 28! Turn to I and stop there.

FIG. 14 The rear end part 52 of the pushing angle bar 28 contacts the convex part 56 of the hammer 51 and pushes it until it engages with the hammer m6G and the trigger hook.

In FIG. 12, the pushing angle bar 28 is
It acts as a push back. The part 56 is attached to this pusher 58 with a center pin 57, and is pushed up by a spring 88 and moves by the angle that the part 56 forms.At the same time, it pushes the part 52 forward and also has the effect of pushing up the part 52 that has rotated downward. ing. A stopper 92 is attached to the rear end of a spring shaft 63 for firing the hammer 51 to provide a play of about 3 mm between the herb 48 and the hammer 51, as part of prevention of sudden firing. In the multiple-shot combination gun shown in Fig. 2, the gun barrel 3 is fixed, and the nose 5 and part 34 of the engine section move back and forth together. , it can be done if you take the concept into consideration. Also, it doesn't matter if it's a ground type gun. It is done in the same way as a rifle's four shot shots.
