CLASS 72: Firearms and Gesc:

The invention described here aims at the following innovations in automatic firearms (pistols, rifles or cannons). In the case of the self-contained firearms known so far, either the barrel is set up to be displaceable and, as a result of the back material, moves backwards with the breech at the moment of the shooting, whereupon it is pushed forward again into its normal position by a spring or the subsequent breech, ¹ or the barrel is stuck and only the breech is moved backwards by the back and then pushed forward again by a spring.

The weapon to be described, on the other hand, is not a movable shutter, but a solid fabric surface available, which the back. stofs alone while the run at Shots as a result of the counteraction separates from this surface of the material and goes forward. For this purpose, the barrel is in a corresponding guide around a certain distance can be moved forward. Its normal (closed) The position is therefore not the front, but the rear, and it is brought into the same by a spiral which is best of all spiral .Spring pushed back. Depending on the purpose of the weapon, the barrel is only straight go forward or make a rotating movement around its longitudinal axis.

In the accompanying drawing are firearms constructed according to the new principle indicated shown, and it shows:

Fig. Ι in vertical longitudinal section an automatic Multi-loading pistol in ready-to-use position; the barrel is pushed back completely and contains the first cartridge,

Fig. 2 shows this pistol in the same view at the moment of the fired shot. The barrel is in its foremost position; the cock has already jumped back and the second cartridge already lifted.

Fig. 3 shows in vertical longitudinal section an automatic multi-loading rifle in the same position, like the pistol in Fig. 1.

Fig. 4 shows this rifle in the same view as in Fig. 3 and in the same position like the pistol in Fig. 2, but the cock is cocked by the movement of the barrel.

Fig. 5 shows a vertical longitudinal section of the rear barrel end with the fabric base for cartridges with or without a burnable sleeve.

With smaller handguns, such as. B. with the pistol shown in Fig. 1 and 2, because of the weaker charge that the cartridge has, it is permissible that the barrel is no longer coupled to the material surface at the moment of the shot, but only under the pressure of the barrel spring F. rests against the fabric surface S. The pressure of the spring and the moment of inertia of the barrel then provide the necessary resistance when firing. The barrel L, which in this weapon only has a straight forward and backward movement, is, as can be seen in FIG. As can be seen, the barrel L is surrounded by a tube R containing the spring F and guiding the barrel in its longitudinal direction. Below the

The magazine K is attached to the rear of the barrel. In the drawing, a box magazine intended for parcel loading is shown, the type of which can, however, be of any desired type.

The hammer H can either be cocked by hand at the hammer's tail - as thought in the drawing - or by means of the Züngeis Z - as with revolvers - in which cases the operation of the weapon is only semi-automatic, which has certain advantages. However, the tension of the hammer can, if desired, also be effected automatically and derived from the movement of the barrel by some transmission, of which an example will be given later.

The Hahnschlofs, when tensioned by hand, is best a recessed, yet this is. well-known device not shown here.

At the moment of the shot, the mechanism then assumes the position shown in FIG. 2, which represents the moment when the barrel is thrown all the way forward to its stop in the tube R and the reaction of the now tensioned spring F begins. The rapid movement of the barrel and the springing back of the hammer allowed the following cartridge to rise so high that it is completely or almost in one axis with the barrel chamber, so that the barrel, which is springing back under the action of the spring F, pushes itself over this cartridge, the following cartridge is pressed down slightly.

The means by which the respective uppermost cartridge is retained, as is the ejection the ejected case is effected are not specified here; it's just about note that they may be similar to those of firearms with moveable breeches.

A second construction, especially suitable for repeating rifles and cannons, is shown in FIGS. Here must, because of the strong charge of the cartridge run L offer gröfseren resistance to Vorschleudern than in the previous case, and this is achieved, that the course of L barren on a particularly screwed it part of one, two or more Verschlufswarzen WW are attached, which have a certain helical slope. These lugs fit into correspondingly shaped recesses or abutments η η in the housing G. When the barrel receives its impulse forwards when firing, the lugs WW , which are helically guided in the abutments η η , initially cause a rotating movement (e.g. by 90 ° ) of the barrel, whereby the warts emerge from their abutments in the housing G and whereupon the barrel continues in a straight line due to its inertia until it comes to a stop in the tube R serving for its guidance and whereupon the reaction of the barrel spring F begins. The described rotation of the barrel through the warts WW can be promoted or slowed down, depending on the direction of the twist, by the rotation which the projectile moving in the twist tries to impart to the barrel.

In Fig. 3 and 4 it can also be seen how the cocking z. B. can be done by a self-machined clamping surface on the run, but any other known. Motion translation can be applied. The button X is used to move the barrel by hand . As regards the magazine K and the feeding and ejection of the cartridges, what has already been said in connection with FIGS. 1 and 2 applies.

For a cartridge without a sleeve - z. B. made a of a solid explosive material - or with a combustible sleeve, the seal, as shown in Figure 5, by an inset in the Stofsboden, possibly conical bit, bowl-shaped ring made of any P, resistant material, for.. B. platinum, over which the barrel slides and which rests against the inner wall of the barrel when the shot is fired.

For a better explanation of some details of these firearms - and in particular the impact - and clamping device is in the accompanying drawing an embodiment of the firearm illustrated in detail.

Fig. 6 shows such a weapon in longitudinal section in the open position and

Fig. 7. the same in the closed position.

Fig. 8 shows the rear or occlusion portion of the barrel alone.

Figure 9 is an end view of the housing with the shaft removed.

FIG. 10 is a cross section through the housing along line AB, FIG. 6.

Figures 11 through 16. are details.

The embodiment of a striking and tensioning device shown and described here consists essentially of the slider g, which is movable on the underside of the housing and which carries the striking pin h at its rear end and the tension lug or lug i at its front end. In order to allow free passage from the magazine into the interior of the housing, the slider g is perforated or shaped like a frame, as can be seen from FIG. The striker spring k is mounted in the rear or tail part of the housing and has the tendency to drive the slider g forward into the position shown in FIG.

Claims (4)

The barrel is provided with a recess / on its underside, in which the clamping lug i of the slide g comes to rest when the barrel is closed, the latter being kept in its front position by spring k. If the barrel is turned upwards, ie unlocked, the front inclined surface Z ^{1 of} the recess Z acts on the lug i in such a way that the sliding piece g is moved back a certain distance, the mainspring k is thus tensioned. In this position shown in FIG. 6, the slider g is held in place by the trigger device to be described later. The slider g has reached its outermost tension position before the barrel has completed the entire way of its opening rotation, whereby the clamping lug i has also reached the rear end of the recess / of the barrel, so that the shorter side of the recess /, Fig. 8, against the side of the wart i comes to lie. These two contacting surfaces are beveled accordingly, so that with the continued rotation of the barrel the protrusion i is forced out of the recess /, that is to say the sliding piece is brought down to give way at this end. This evasion is made possible by the fact that the sliding piece g is loosely inserted into the rear of the housing, while its front end i ¹ is guided in a cutout m, FIG. which takes the end of i ^{1 of} the slider when the tension is complete, merges into a recessed gradation m ¹ , into which the nose i ^{l of} the slider can enter if it is pushed downwards, as described above, so that the run is now free can slide forward over the wart i. When the barrel is moved back and has reached its locked position, its recess Z comes to rest over the nipple i and the slide piece g, which was tightened a little more than the sear collapse caused, is activated by the spring k pushed a little forward and thereby by virtue of the bevel of the front end of its nose z ¹ with the latter in the height of the recess m, so brought back into a horizontal position in which it can move forward after triggering the trigger, the striker h the Capsule hits the cartridge in the barrel. The discharge device (Fig. 15 and 16) consists of the trigger or trigger blade Z with the hingedly and resiliently attached thereto hook \ and in the housing or, as shown here, is rotatably mounted in the magazine frame and by a spring with its rear hooked end always to above compressed sear 0. the hook is \ of Züngeis with the hook of the sear 0 engaged in the normal position, however, is the slider g in its forward, non-tensioned position, pressing a on the latter befindlicher approach g ¹ the hook \ of Züngeis down and holds the same, besides engagement with the hook of the lug 0. If the slider moved backward (stretched), so hook \ is only so much free, that he located on the underside of the sear 0 can create, while the latter more excellent even from the Slider is depressed. If the voltage is completed, the locking occurs o ¹ of the stud 0 against the corresponding locking surface g "of the slider g and arrested the same, at the same time, the hooks of the two parts come of the trigger into engagement. If now, the trigger pulled, thus triggering hook \ ^λ the tunnel 0 and the slider can be moved forwards quickly. in this case, passes approach g ¹ again via the hook \ and holds the same, besides engagement with the hook, the lug 0, as described above. however, a release of the slider is the position as a result ■ the nose z ' ¹ in the recess, m ^{1 of} the housing is not possible and can only occur after the nose i ^{1 has} entered the cutout m , ie when the barrel is closed. If the magazine is to be filled, the barrel must be turned up and pushed forward by hand. In order to prevent the barrel from being snapped back by its spring during charging, a milled recess ρ is made at the bottom of the right side of the housing, as in FIG the one locking barrel W , which is attempted to rotate by its spring in the direction of the locking, to the right, inserts, whereby the return of the barrel is inhibited. After the magazine - loaded, the barrel is given a slight turn to the left by its grip in order to rotate the wart W out of the milled recess ρ , whereupon the barrel is driven backwards by its spring and locked. The cartridge extractor r and the ejector s are still attached to the fabric base. At the rear end of the barrel (Fig. 13) a screw-like loosening surface t is incorporated . Patent claims: i.
