Definitions
- the invention relates to an arrangement of a closure and a projectile enclosing the projectile, which is extended to the rear by a powder-receiving space having a cylindrical wall made of projectile material or projectile jacket material, which protrudes to the rear, slightly inwards towards the center axis of the projectile has moved in and is in close contact with the butt plate of the breech when launched (preamble of claim 1). Furthermore, the invention also relates to a weapon belonging to this arrangement (claim 4).
- caseless ammunition While the main advantage of caseless ammunition is that it saves costs and weight for the cartridge case, it is precisely due to the lack of the cartridge case that difficulties arise with the heat dissipation, since it has been one of the main tasks of the cartridge case - especially with self-loading weapons - to get heat from the weapon to transport.
- the object of the invention is to eliminate or at least alleviate the above problems in a projectile which contains the powder charge and ignition.
- the breech has an annular groove undercut to the firing direction and centered on the axis of the soul, at the edge of which the rear, drawn-in edge of the projectile sits when reloading and into which the edge is closed when the breech is completely closed
- Deformation is pressed in such a way that when the breech is pulled back, the projectile, unless previously fired, is pulled out together with it (claim 1).
- the ring groove is a training, which is located within the space that is exposed to the hot powder gases, but is so extensively connected to the mass of the bump bottom that heat flows away there, even if the weapon should be shot in continuous fire. Soiling is also only a marginal phenomenon, since the sharp-edged, rear end of the powder chamber of the projectile frees the ring groove again with each shot. Deforming the rear edge of the projectile in the
- Annular groove of the butt plate is preferably only immediately before the closure of the closure, if with a repeater or
- the ignition charge is so far forward relative to the firing pin of the breech that it can only reach it when the retracted edge of the projectile is pressed into the annular groove (claim 3).
- the interaction of the retracted edge of the projectile and the ring groove of the butt plate fulfills a dual function: first, it enables the extraction of a non-fired projectile, and second, it ensures that firing can only take place when the retracted edge is pressed into the ring groove is.
- a removed cartridge is usually no longer used, but could just as well be used again if it is not a cartridge failure, since the retracted edge is widened again when detached from the ring groove so that it is again in the ring groove is pressed in if the projectile should be fired. A corresponding course of the edges of the annular groove supports this pressing.
- the retracted edge is usually plastically deformed in this process, since the tombac used is a relatively soft, ductile material. But it would also be possible to use a hard, resilient material, which by the
- Ring groove is briefly expanded and then falls into the undercut.
- the shell of the projectile could also have longitudinal slots that form individual metal strips that are more easily resiliently deformed. All of these designs have the feature that, when the weapon is completely closed, they nestle into the ring groove and, viewed from the front, are seated in an undercut. In principle, it is irrelevant whether this nestling is springy or - preferably - plastic.
- the invention relates, as already noted above, not only to the arrangement mentioned, but also to a multi-shot weapon with such an arrangement and a magazine, the magazine being designed as a projectile magazine, the uppermost or next to be followed projectile with its central axis approximately lies on the extension of the soul axis of the barrel, and the closure of which is provided with a butt plate with a shaft-like extension with a diameter which does not exceed the diameter of the projectile (claim 4).
- the magazine will generally be a rod magazine fed from below, but could also be, for example, a plate magazine or some other tracking device that can be configured analogously.
- the new projectile is straight and not tracked along a curve, as is conventionally the case because there is no need to eject an empty cartridge case that hinders the reloading process.
- the top floor is pushed forward by the lock and can be pulled straight out again if necessary, since the lock has not yet moved the next floor.
- the extended projectile can be ejected by, for example, a transversely suspended flap which passes through the projectile and on which it is ejected. Manual operation would also be possible.
- a particularly simple embodiment consists in that the magazine encloses the uppermost or next floor to be tracked on the side remote from the other floors by a web (claim 5). This not only determines the position of the projectile in a simple and robust manner, without the projectile being damaged by magazine lips or similar edges. If, moreover, the closure can be ascertained in a position in which, after opening the closure, one firmly molded into the annular groove on it
- Projectile is in the area of the web (claim 6), a simple, strong pulling out of the magazine is sufficient to release an extended projectile from the annular groove. If the web only extends over part of the length of the magazine, the projectile can simply be detached from the annular groove and falls out of the magazine shaft behind the removed magazine.
- the weapon according to the invention can be, for example, a repeating weapon or a shooting weapon
- the firing pin is then firmly attached to the closure (claim 8). This is completely harmless, since the firing pin can only come into contact with the primer charge when the projectile sits on the front end of the cartridge chamber and the resilient breech consequently forms the rear edge of the projectile into the annular groove.
- the pressure of the firing gases is much lower than in the case of a rifle.
- the bullet edge molded into the annular groove creates a certain seal that reduces outgassing in the first phase of the pressure build-up. If, therefore, a removal or shielding of the gases escaping to the rear is provided so that the shooter does not take them into account, or does not take them too seriously, additional measures for sealing the chamber can be dispensed with.
- a development of the invention provides that the cartridge chamber receiving the projectile is extended to the rear, and that the breech closure has a diameter which is only slightly smaller than that of the cartridge chamber and its extension in order to seal it (claim 9). Adequate sealing is thus ensured, with only the lengthening of the cartridge bearing along the rear ensuring that the barrel remains locked to the rear as long as this would also be ensured with a weapon with a ground lock due to the length of the cartridge case.
- the closure in the area which penetrates into the extended cartridge chamber has at least one sealing ring with respect to the latter.
- at least one sealing ring can be replaced by an annular groove on the outside of the closure. The ring groove creates a certain labyrinth effect and also cleans the walls of the extension of the cartridge chamber from residues of the powder charges. It can also an actual sealing ring for the reliable
- the described weapon differs to a certain extent from conventional submachine guns: for example, the magazine can only be inserted or removed when the breech is cocked. But this is insignificant; for example, a second rest can be provided for the magazine to be inserted, which holds the magazine in place when it is not fully inserted and the closure is in the front position. After tensioning the breech, the complete insertion of the magazine can be a further safety measure, or a spring can cause this insertion and fixed locking in the actual holding latch, so that no further manipulation is required and the operation largely corresponds to that of a conventional submachine gun.
- FIG. 1 shows a section through part of a submachine gun, with the arrangement according to the invention consisting of a projectile and breech or bump bottom during tracking,
- FIG. 2 shows a section through another part of the submachine gun, the arrangement according to the invention consisting of the projectile and the impact floor showing directly when the projectile is ignited,
- FIG. 3 shows a section through the submachine gun on a smaller scale ready for fire, with insignificant parts being omitted for the sake of simplicity of illustration
- 4 shows a section through the submachine gun shortly after it has been pulled off, when the breech begins to feed the top floor out of the magazine (this illustration corresponds approximately to FIG. 1)
- FIG. 5 shows a section through the submachine gun at the moment of firing (this representation corresponds approximately to FIG. 2)
- Fig. 6 shows a section through the submachine gun immediately after firing, when the breech begins its backward movement
- Fig. 7 shows a loaded magazine removed from the submachine gun, in which the top floor is cut.
- Fig. 1 parts of a submachine gun are shown in approximately four times magnification and in section, with a cylindrical closure 1, which in the illustration is moving in the direction of the arrow.
- the breech 1 has a diameter which is slightly smaller than that of a projectile 13, which is located in front of the breech 1 in a magazine 9, is loaded from below by a spring (not shown) and is prevented from doing so by a web 11 to get out of magazine 9.
- the web 11 extends only about half the length of the magazine 9, so that when the magazine is removed (FIG. 7) projectiles 9 can be tracked from above and behind in order to
- the magazine 9 is provided with an opening through which the top floor 13 can be pushed forward from the closure 1 into a "cartridge" bearing or bearing 37 (FIG. 2).
- the projectile 13 has on its outside between the first and second thirds of its length (seen from the front) a shoulder 15 which at the end of the bearing 37 (FIG. 2) on one corresponding paragraph (39) can sit on and define the exact position of the projectile 13 in the weapon.
- the subsequent, approximately cylindrical jacket-shaped jacket 17 extends to the rear and is pressed into trains and fields of the barrel 41 (Fig. 2) during the shot to reach the leadership.
- the end edge 29 of the jacket 17 is drawn in, that is to say deformed inwards, and forms an end edge 31.
- the space enclosed by the jacket 17 is largely filled with a propellant charge 19 which extends to the retracted end edge 29.
- a propellant charge 19 which extends to the retracted end edge 29.
- the front surface of the closure 1 is called the push floor 3, which is circular overall and in the middle of which a fixed firing pin 5 is formed. This is surrounded by an annular bead 33, which forms a transition to an annular groove 5, which sits outside and behind the annular bead 33 and differentiates it inwards.
- the length of the retracted edge 29 corresponds to the distance between the front surface of the annular bead 33 and the rear surface of the annular groove 5.
- the outer diameter of the annular bead 33 is a little smaller than the inner diameter of the retracted end of the edge 29.
- the cylindrical part of the closure 1 also has two circumferential grooves 25, in each of which a very hard sealing and scraping ring 23 sits, which scrapes dirt from the extension of the “cartridge” bearing (not shown here).
- the associated circumferential grooves 25 are larger than the rings in order to be able to accommodate dirt if necessary.
- the closure 1 moves in the direction of the arrow, it penetrates without resistance with the annular bead 33 into the retracted end of the retracted edge 29, the end edge of which rests on the outer flank of the annular groove 5 (annular groove 5 and Ring bead 33 are centered on the core axis). At the same time, the foremost edge of the annular bead 33 sits on the propellant charge 19.
- the closure 1 drives the projectile 13 in front of it, under the web 11 of the magazine 9 and through its opening 27 into the extension 35 (FIG. 2) of the bearing 37 until the paragraph 15 of the projectile 13 on the paragraph 39 of the barrel 41 sits, the shoulder 39 limits the bearing 37 to the front.
- the breech 1 tries to move even further due to its force, in this case presses the firing pin 7 into the primer 21 and at the same time presses with the lower flank of the annular groove 5 against the end of the retracted edge 29 of the projectile 13 such that this completely deformed into the annular groove 5.
- the projectile 13 would sit firmly with the deformed end 29 of its casing 17 in the annular groove 5 and would be held by its undercut part, so that the projectile 13 when the closure 1 is withdrawn again from the bearing 37 and its extension 35 would be pulled out.
- Floor 13 could then be removed.
- the jacket 17 would be torn out of the annular groove 5 and would leave the barrel 41 with the rest of the projectile 13 to the front.
- a sealing ring 43 enters the extension 35 shortly before firing and seals during the first phase of the firing against the then maximum pressure in the bearing 37.
- the closure 1 is extended towards the rear by a considerably larger (and heavier), circular-cylindrical closure body 45, which carries a circumferential groove 47 into which a trigger device (not shown) engages.
- the closure 1 and closure body 45 is thus completely rotationally symmetrical and does not need to be held in any position.
- the interior of the closure body 45 has one to the rear open, central bore 49 in which a closing spring
- closure 1 and closure body 45 are guided in a corresponding chamber of a plastic housing, into which a barrel holder 51 is also injected, in which the barrel 41 is held by means of a union nut 53.
- Fig. 3 shows the essential parts of the submachine gun (without trigger device) in the cocked state before the shot.
- the trigger device holds the closure 1, 45 in its rear position shown.
- the distance between the butt plate 3 and the web 11 of the magazine 9 is dimensioned such that the tip of an extended projectile 13 is gripped by the web 11 when the magazine 9 is pulled out and broken off from the butt plate 3, so that the projectile 13 that has not started behind the Magazine 9 falls out of the magazine shaft when it is removed from the weapon.
- the butt plate 3 grips the projectile 13 (FIG. 4), introduces it into the bearing 37, where the drawn-in edge 29 is formed in the undercut annular groove 5 (FIG. 5).
- the projectile with propellant charge 19 and primer 21 was ejected from barrel 41, while breech block 1, 45 began to accelerate in the opposite direction (backward) due to recoil and gas pressure (arrow in FIG. 6).
- Fig. 7 shows the upper part of a cut magazine 9, the top floor 13 having been cut again, so that propellant charge 19 and primer 21 are clearly visible.
- the weapon is extremely simple and is extremely uncomplicated to manufacture. Nevertheless (due to the screwed barrel 41) the life of the weapon is very long. It is therefore not only an excellent weapon for military use in peacetime, but also especially for police use.
