Description

This concerns the semi-automatic BHHTOBKII with

The barrel, in which the recoil force is used to open the bolt and for you, throws the boom sleeve.

The device of the proposed pinning can be seen from the attached drawings, where F1; I is a longitudinal rifle incision when parts of the mechanical mechanism are lighter; FIG. 2 is a longitudinal section along LB in FIG. 1; FIG. 3 and 3 DIRECT} U of the shutter; FIG. 4 shows a view of the rifle 5 without a lodge; and FIG. 5, a 5-lock button,

The receiver box 1 (figs, 1, 2) precedes a through tube, into the front end of which the barrel 2 is screwed in, the middle part of the steo box having a smaller inner diameter at the top is open, forming a receiver into which its front protrusion 4 enters Shutter 5. In addition, a cartridge is placed in the open at the top of the attachment when the rifle is loaded, and arrows are thrown onto the cartridge through the window.

The rest of the inner cupboard of the receiver is placed at the middle most thickened part of the bolt 5, as well as its tail part .6 (fng 1). The rear end of the barrel box inside has a cut for tightening the jacket, 7 (fig, 1),

The shutter 5 has a cylindrical. The front part 4 of the gate is beveled at the sides, rounded at the bottom, with this protrusion, with which the gate 5 freely enters the receiver 3 of the receiver. In the upper part of the protrusion 4 of the bolt, a socket 19 is drilled, in which the stretcher 20 is placed, fastened to the bolt with a pin 21. The middle portion 5 of the bolt is most thickened, while the tail portion 6 of the bolt has a slightly smaller diameter, so that the tail portion 6 of the bolt is the length has both sides beveled, which makes it possible, on the middle thickened part 5 of the shutter, on its sides to make two holes 22 (Fig. 2) in which the left ends of the guide pins 15 are placed, with wearing springs on them, to their ends and abut against the collum above the side holes 22, thereby prompting the shutter 5 forward. The through holes 23 in the bottom guide the right ends of the pins 15 as the shutter moves. The slopes on the tail section 6 of the bolt have another purpose, namely: to prevent the bolt from turning; for this, as already indicated above, a guide washer is worn on this tail portion of the bolt. 9 is coiimodally standing relative to the receiver and having a window 24 (Fig. 3) of such an outline, which has a tail section of the gate in cross section. By

The central axis of the bolt passes channel 25 (Fig. 1), in which the drummer 26 is placed with its battle spring 27. The spring 27 is constantly urged by the drummer forward. The left end of the pitch; kina upirasts in the back of the main part, while the right in the locking button 28 (Fig. 1, 2), pressing this last to the delay 29. The drummer in the upper part has a through-groove 30 along the entire length. Screw 31- fastened to the stop, e penetrates with its lower end 32 into the through groove of the striker indicated above and thus prevents the striker from turning. The lower part of the firing pin is cut off on some protrusion, forming a ledge 33. This flank of the firing pin, when it is cocked, rests on descent 34. The front part of the firing pin is provided with a striking, appropriate form, with which the drop firing pin causes the ignition of the PTTRON. The locking button 28 (Fig. 5), against which the right end of the Goa firing pin rests, has a cylindrical shape. In its middle part, the locking button 16 has an annular protrusion which, when cut, forms two protrusions 37. With these protrusions, the button simultaneously enters the slot 38 of the tail section of the tail section to

. in the grooves 39, selected at the bottom of the straps 29 (Fig. 1), which serves to pull away for: the solution back from the hand. The right end of the locking button 16, the passage through the through hole, protrudes slightly out of this last. Such a device and the location of the locking button provides, on the one hand, against arbitrary screwing of the bracing 29 from the tail portion of the bolt, and on the other, it allows the disassembly and assembly of the bolt to its parts without any tools.

On the side of the barrel korebki. selected groove 42 (Fig. 2). In this slot, a lever 43 (shutter stop) is placed. The lever 43 is mounted on a pin 44, which is mounted on the receiver and on which it can swing a little.

The left side of the lever 43 is provided on the outside with a small protrusion 45 with notches for controlling this lever by hand, and on the inside of the arm 41 in which a spring is placed, 46, the other end of which is located in the corresponding socket. . in the groove of the receiver.

on the receiver and passes exactly lsd shk pkoy 51 stud 52 of the lever 43 (Fig. 4). Such a mutual arrangement of the studs 50 and 52 provides the stud 52 of the lever 43 from falling out. The descent 34 has four protrusions: the first protrusion 53 serves as a reflector, the second projectile 54 is an emphasis for the drummer, the third protrusion 55 comes in contact with the trigger 56 n, finally, the fourth protrusion 57, the descent abuts the finger 58 of the safety lever 59, when on the ice U working position. Fuse 59 (Fig. 1), mounted on a stud 60, mounted on the receiver, is equipped with three processes, the first of which 61 serves to control the safety lever by hand, for which the lower part of this process 61 is notched and comes out of the box to the outside. In the second spine 58, a drop 34 rests when the fuse is in the working position, the third spike 63 limits the deflection of the fuse to the left when it is withdrawn from the working position (Fig. 1). To secure the fuse in its working and inoperative position, a flat spring 64 ukr is captive at the bottom of the receiver with a cog 62, which simultaneously counteracts the unscrewing of the barrel from the receiver. The other end of the flat spring 64 has a double fold 65. With these folds, the spring alternately rests against the bolt 66 of the fuse tightly plugged into the body, thereby securing the fuse in two different positions, i.e. working and non-working. The trigger 56 is mounted on the pin 67, which is fixed on the eyelet 68 (Fig. 1 and 4). The eyelet 68 is reinforced in one way or another, for example, by two rivets 69 downward of the receiver. To the left of the stud, the trigger 56 has a finger 70, with which an ok also enters a soggrkosnoveniye with a protrusion .55. and .55 of the descent 34 (Fig. 1), constantly clamping by the action of the spring 71 of the protrusion 54 of the descent to the drummer. The charging and preparation of the rifle for a shot are as follows. They take an intovka and left hand, with their right hand for tt zhku 29 they pull the aatvor back to the tail. After that, let him go. The winding up, going the insignificant way backward, is uptreated by its middle most thickened part 5 to the tooth 47 of the lever -43 - it is held in this position. Receiver 3 in this position of the shutter will be open, which makes it possible to invest in the receiver cartridge. If now, while continuing to hold the rifle with his left hand, behind the forearm, with this hand grip, press the protrusion 45 of the lever 43, then the latter will turn a little on the axis and release the bolt from the stop to the tooth 47. The bolt is not held by anything else, will move forward and push the cartridge into the barrel chamber. The rifle will be charged wife. In the same period of time, the firing pin 26 will be thrust into the tooth 54 of the descent and will become a combat platoon. If you now pull the trigger, the trigger finger 70, entering the contact with the trigger 34, will turn it. The tooth 54 of the trigger is lowered and the airborne 26, not retained by anything else, rushes forward under the action of the mainspring, ignites the cartridge, causing a shot to occur. By the effect of recoil force, the bolt will be thrown back, at the same time the arrows on the sleeve extended by the extractor 20, the reflector 53 will be thrown through the window 3 to the receiver. The bolt on the return path stops the tooth 47 of the lever 43 and remains open, which will make it possible to re-insert the next cartridge in npnev, nick 3. If you now press the lever -43, the bolt will close again and the rifle will be charged again, pressing on the hook 56 will call again: an, a shot, after which a high will occur;
