Description

The invention relates to devices for automatically setting the burning time in shells with a central channel and / ring distance composition openly located in the bottom of the projectile .V

 According to the invention, in a device in a Lewis-type grenade launcher, a npk rearranged on a distance scale, using a cylindrical gear and a flywheel, a rod with a ladder, was used. The threaded rod is unscrewed from the rack connected to the piston of the grenade launcher and intended, when the bolt is opened, to push the nut through the central channel of the next projectile and to turn With its screwed rod and disk with a hole through which the remote composition should be ignited at a certain point , according to the installation of a remote scale. In the drawing of FIG. 1, a longitudinal section of the device is shown; FIG. 2 longitudinal section snar yes; FIG. 3,; 4 and 5- details.

The body of the device (Fig. 1) consists of a duct /, a barrel screwed into a box and a radiator 2 of a cooling barrel.

In the box 7 there is a longitudinal groove along which the slide moves, and a little lower and to the left is another groove for moving the pillar b. On the left side of the box there is a vertically attached magazine 3, into which the shells are placed. Along the entire length of the box. Helps a cylindrical gear, turning in any direction a rod with a gear, a piston mounted on a rack 6. At the back of the box, as in Maxim's machine gun, a backfire is inserted with handles and a lever 7. On the right side of the box there is a window i through which arrow sleeves are ejected (the dashed line shows the bolt in the front end position) ..

The shutter, unlike the shutter Lewis; a, does not have a screwed-in tail in the back. There are two springs against window 8 on top of the box. I have cutouts in my blades with which they hold the projectile still until the rod 5 with gear 5 comes close to the projectile. Below, under shop D there is a feeder, which is not visible on the drawing. A cap / 7 with a spring is put on the top of the luggage compartment 3, all the time pressing the bottom of the projectile. There is a latch on the right side of the cap

which passes inside the cover. When the lid is worn on the magazine, the latch toe rests on the notches of the toothed cloth located on the right side of the magazine, and this allows the lid 11 to lift up. The latch tail is always wrapped around the spring. There is a ring 14 on it which serves to pull it off when the cover is removed. 1

Unlike the Lewis machine gun, the piston of the device on its shaft has a strut 6, in which the shaft with the gear is screwed loosely into its ear. In order to move the strut freely, radiator 2 has a notch in which the piston moves. Hour 6 is slightly bent and stands on the piston rod as if a rod at its thin end inside the void (in the form of a tube), into which the quadrangular rod 26 (Fig. 2) of the grenades goes in while pushing the metal grenade nut 5.

Pomegranate (Fig. 2) is similar to ca. gran (atu Dia konova, only thinner and longer than the last. In the middle there is a through hole 2 / along the whole length of the grenade (Fig. 2). On the outside of the bottom of the grenade there is a strong cable in the groove, (wick) 23. One end cord inside the grenade and connected to the explosive, and the other freely. Unless the cord 23 is ignited from the end connected to the explosive, the gap i; the panels follow immediately, and if the cord is ignited from the opposite side, it will take some time before what followed the gap.

To regulate the ignition of the cord, there is a circular disk 24 (Fig. 5) round in diameter of the grenade bottom, equipped with an opening 25, which passes through the fire of burning powder that ignites the cord: The disk 24 rotates, and therefore the opening 25 can be placed anywhere in the cord. The disk 24 is tightly mounted on a thin quadrangular threaded rod 26 (FIG. 3), which, in turn, is passed into the nasty hole 2 / grenades. The free end of the rod 26 passes into the quadrangular hole of the metal nut 27, which is located in the longitudinal opening of the grenade. On the nut 27 there is a protrusion 28 freely moving in the screw-shaped groove 22 of the opening of the grenade. If the nut 27 is pushed deeper into, the protrusion, 28 will slide along the screw-shaped groove 22 and this will cause the nut 27 to turn. Finally, turning itself, turns the four-pointed rod 25, and since the protruding end of the rod is tightly mounted on the disk 24, and that will turn, and, therefore, the opening 25 will move along the length of the cord 23. The nut 27 slides freely along the quadrilateral rod 26; so that during its turning it does not move inwards, the 2P disk is used, which is put on the bottom of the grenade and together with it is put into the gunpowder in the gunplate, Dd eliminating the friction of the disk 24 into the babyphone erip turning on the 2P disk, and also for o) 5a easy turning of the disk 24 in the arr for the quadrilateral. There is a needle, 30, which abuts against the disk 29.

To pass fire to the cord in disk 29. there is a hole 31 (fig. 4) in the form of a cut along the length of the cord. Disk 29 is also prevented from preventing the fire of a burning Heap from falling on the cord to an undesirable place.

-An grenade is inserted into the sleeve, in which there is gunpowder ejecting the grenade. When a grenade comes out of the barrel, the disks 29 to 24, together with the rod 26, as well as the nut 27, from the oncoming air, which with a force pushes into the hole of the face, will fall out of the latter and this will eliminate further resistance to pain.

These shells, numbering 30-40, are placed in magazine 3 in two or three rows. Then a cover 7 / is put on the magazine 5. After that, swing the jitter J2 to the right side of the center gear 4 until the stylus 33 is not against the desired digit on the distance scale 34. Assume that the force of the gases in the projectile will throw 2,000 meters away , but the target for which the shooting should be carried out is only from 900 meters to the shooter, then the cylindrical gear 4 needs to be turned so that the feather 3 becomes divided 9 of the distance scale L. At this time, the following will happen: cylindrical gear 5, turning c'mon, turn and rod Hb 5 which, owing imeyuschims thereon rifling will be freely rotatable rack 6. .tak manner, the rod 5 can be unscrewed from the rack or 6 or again tighten ietim make it longer in order chtoby4 it could further promote nut 27 grenades. After all this, together with the shutter for {Handle / P, back, and since there is a rack b on the rod of the grrnshn, it together with the rod 5 will approach store 3; but at this time the feeder will have time to capture another projectile from the bottom, store 3, and push it into the cutout of the spring 9, which firmly holds the projectile in one place; the valve and the piston still continue to move back until the rod 5 advances the nut 27. deep into the grenade to failure (if it was so long with, rod 5), i.e. that distance, which is indicated by the opro 33 of the distance scale 34. Under the action of the rod 5, the nut 27 moves deeper into the grenade and simultaneously rotates the rod. The rod rotates itself and rotates the disk 29, which sets its hole 25. to the desired, previously precisely calculated place on the cord, namely the place that corresponds to the division on the scale 34, i.e. 900 meters; If you need to shoot at 1500-2000 meters, then the nut 27 needs to be pulled further into the grenades, and hole 25 will be further away from the end of the cord that is connected to the substance, i.e. the cord will be ignited further from the explosive, and, consequently, it will burn longer until the moment of the explosion. All this work is done when the valve and piston are retired for the first time. Now the piston with the bolt must be lowered; at the same time, the rod 5 will come out of the grenade hole, but by its movement the bolt will not yet move the adjusted shot into the chamber, since the spring 9 cut-outs have not yet released sleep | d yes. Then it is necessary to repel the pore, 1st and back again. As soon as the shutter stops the window 8, the feeder will, with its second consecutive sniper, push the adjusted snipe out from under the notches of the springs 9 and will take its place in the notches in order to push the nut. When the piston is released forward, the bolt pushes the adjusted projectile lying in the slit and advances it into the chamber of the shotgun DL9.
