In all the figures the same parts are denoted by the same letters.

A is the barrel (Fig. 1 and 2) of any shape and size. B is the locking sleeve screwed to A at b; The latter has two lateral extensions b ^l b ² , which are shaped in such a way that on the one hand they have two inclined planes χ as support surfaces for the sleeping thumbs DD and on the other hand tongues y , which enter under projections \, which are provided for this on the movable locking piece.

This device enables precise engagement of the sleeping thumbs DD and prevents mutual removal of the extensions b ¹ b ^{2 of} the locking sleeve B from one another under the pressure of the sleeping thumbs. C is the movable locking piece (FIGS. 1, 2 and 6), which aims to seal the rifle tightly by means of two sleeping thumbs DD ^{mounted in special recesses c 1} and c ^2; it contains the required hole for the firing pin P and is provided with the aforementioned projections \ \ . The movable locking piece also carries the cartridge extractor e and a lock 5. for the firing pin and the lever Z; its tail is provided with a notch c ³ for hooking onto the locking piece i and the resulting cocking of the firing pin P.

The thumbs DD (FIGS. 2 and 8) rotate about their axis d in the movable locking piece C; on their lower side they have small extensions d ¹ , Fig. 3, intended to open them when tilting for the purpose of restricting the rear by placing them on two inclined planes / ² and / ³ (Fig. 2a) of the lock housing. At d ² these thumbs are hollowed out to let the firing pin head through.

The cartridge extractor e is held (Fig. 6) in the upper part of the movable locking piece by means of a piece e ^{1 which is} held at one end by a screw e ' ² and at the other by a hook e ³ . The piece e ^{1 also} serves as a pivot bearing for the thumbs D D. As soon as the former has been removed, the latter can be brought into place.

The locking piece lever L (Fig. 1, 2 and 7) is used to open the rifle in order to insert a cartridge into barrel A or to remove a cartridge that has remained in the barrel.

If you pull the lever backwards with the rifle closed, it rotates around its axis Z, and its cutouts Z ¹ P encompassing the lower extensions d ^{l of} the thumb DD approach each other until they reach the inclined surfaces χ χ of the locking sleeve B. have left completely.

As soon as this is the case, the movable locking piece C can move back and engage the locking piece i ^{by means of the notch c 3 of} the tail piece c and cock the firing pin P.

If you lock the loading spoon H, as will be described later, the rifle remains open (Fig. Ι a and 2a), you can insert a cartridge and then close it again using the release button i ^{l of} the bolt lock i ,

If you want to remove a cartridge that has been inserted and not yet used from the barrel, with the firing pin P naturally cocked, you must first bring the latter onto the safety catch in order to open the rifle and position it so that the cutout / » ¹ of its head comes to lie opposite the projection of the safety piece s , which latter is intended to lock the firing pin in the case where the rifle is not closed.

The firing pin also serves as an ejector for the empty cartridge cases. On the rear part it has a small protrusion which serves to set it on the safety catch by turning it about 180 °; In the latter position, the section ρ ^{l of} his head allows the safety lock 5 of the movable locking piece to pass through. In any other position, the firing pin P cannot go over the safety lock s unless the latter is depressed by the complete locking of the weapon.

Finally, the firing pin P still has a shoulder or shoulder ρ ² for its indentation (Fig. Ia) through the tip of the trigger /.

The above-mentioned safety lock s rotates around a horizontal pin s ¹ (Fig. 1 and 6) and is constantly pushed up by a spring r to oppose the forward movement of the firing pin, if the rifle is not closed and the normal position of the Lever L is depressed.

The lock 5 is connected to the latter by its approach s ^{2 engaging in a circular groove Z 3 of} the lever L.

The movable locking piece is subject to the action of a counter spring R, which has its support point on the rear part of the locking housing F (Figs. 1 and 2). The latter carries the lower parts of the rifle as a loading spoon, cartridge chamber, bracket, trigger, trigger, and moreover absorbs that excess of reverse material which the springs could not render ineffective; the bolt housing is attached to the rifle stock G by the screws ν and v ¹ , which also hold the plate of the bracket S at the same time, and ensures the strength of the whole; it wears a jacket F ¹ to protect the rifle parts and to ensure a sliding of the barrel and the movable locking piece with gentle friction during the action of the rear material and the handling of the rifle.

The protective jacket jF ¹ has an upper opening / for the insertion and ejection of the cartridge and a lateral Nuth f ¹ for the game of the lever L, the Verschlufsgehäuse containing the inclined planes / ² mentioned above and / ³ h the spoons lock, the Bethätigungsknopf z ' ^{1 of} the lock z, an opening closed by the flat spring R ¹ for entry

guidance of the cartridges when using the rifle as a multi-loader, one opening m for the attachment h ^{l of} the spoon H and a second m ^l for the trigger point J ¹ ; at the front it has a thread for screwing in the magazine or the cartridge chamber.

The magazine is tubular (Fig. I) and takes a certain number of the cartridges introduced at R ^: which are pushed towards the loading spoon H by a spiral spring provided for this purpose and compressed when it is introduced, as will be described in more detail later. It also serves as a support for the spiral spring R ² and the ring M, which are intended to bring the barrel forward again after the return.

The purpose of the ring is to compress the spring .R ² during the return; it completely surrounds the magazine, on which it slides with gentle friction, and is attached to the lower part of barrel A.

In the extension of the magazine is in the lock housing of the loading spoon H (Fig. Ι and 2), ^{rotatable about the pin v 2} and constantly pushed up by the spring H ¹ , which is rolled around the pivot pin j of the pusher J (Fig. 4 b ¹ ). The bucket H has two sloping surfaces' /! ² , on which the movable locking piece C rests during its forward movement in order to depress it and bring it back into the normal position.

The spoon ff acts through the angle piece i ² , which lies under its arm / z ³ , on the lock /, so that when it climbs up automatically - as soon as it is triggered - it presses the lock i down to release the movable locking piece C; as soon as this is the case, the return spring R comes into effect precisely at that moment when the spoon H has lifted a cartridge to the level of the barrel chamber.

As can be seen from the foregoing, the rifle is self-locking effected exactly at the required moment, without loss of time and without premature movement. '

The arm h ^{s of} the loading spoon H has a notch / z ⁴ into which the trigger J enters in its trigger position, as a result of which the spoon cannot work, even with the rifle open, as soon as the shooter has not brought the trigger into its normal position.

This mutual interaction of the loading door, the movable locking piece and the trigger forms an essential part of the present invention and secures infallible the good working of the weapon, whereby it is the shooter in any case makes the master of his shot as if it were a simple crooked rifle would.

A spring r tries to constantly lift the lock i of the movable locking piece.

The lock h of the loading bucket H consists of a screw with several threads, which ^{ends in a lever with a ribbed head 2} (Fig. 1 and 3). If you turn this lever, you can screw the lock or screw h into the cutout of the spoon H provided for this purpose and make the movement of the latter and the cartridges impossible.

If the loading spoon H is raised, as indicated by the dotted lines in Fig. Ia, it itself forms a kind of barrier for the cartridges through its shoulder h ^1. The spring R ¹ forms a stop at r ² for the cartridges passing from the magazine into the spoon.

The trigger J offers no other peculiarity compared to the known triggers than that its arm j ¹ engages in the tooth / z ^{4 of} the arm h ^{B of} the spoon H and inhibits the movement of the latter as long as the shooter has not released the trigger.

The trigger point J ^{1 is} hinged on the trigger at_ / ^2, which goes through the cutout m ^{l of} the lock housing and protrudes over the same in order to stop the firing pin P by means of its shoulder p ² . One pressing on the pivot pin j ^2. Spring r ³ endeavors to keep the trigger tip constantly on the tensioning detent, so that the resistance of spring r ³ must always be overcome when the firing pin is tensioned.

The following describes how the new rifle works, in fact:

a) As a single loader. Whether the magazine is provided with cartridges or not, the loading spoon H in particular must be made immobile, which is done by screwing in the lock h. The lock is then opened by pulling back the movable locking piece C with the aid of the lever L (Fig. 2a) until it is hooked onto the lock i ^{by means of the notch c 3.}

Here, however, the barrel A with the locking sleeve B firmly connected to it slide back until the locking thumbs DD come into contact with the inclined surfaces f ² f ^{B of} the locking housing, approach each other and release themselves from the locking sleeve B , which are then released with the run A by the action of the spring i? ^{2 is} pulled forward again while C remains hooked on i.

The rifle is now open and a cartridge can be introduced into the loading space through the loading opening f of the protective jacket F ^1.

The latter was in a fired cartridge, then the extractor from the medium-e

pulled empty case when pulling back the locking piece by the firing pin P thrown outwards, for what purpose they move about 4 mm further can, as soon as there is no longer any obstacle to lifting the sleeve up and out.

In either case, after inserting the cartridge, one acts on the button i ^{l of} the lock i in order to release the locking piece C , which is then snapped forward under the action of the spring R.

During this movement, as soon as the locking piece C hits the barrel A , the inertia of the lever L puts the sleeping thumbs DD against the inclined planes χ χ of the fixed locking piece B , because at the moment you press the button i ^{1 of} the lock i acts, the lever L is turned back and turns under the action of the stop of the locking piece C on the barrel A forwards; in this case removing the cutouts ^Z1 / ² of the lever L, the two thumb Schlief DD from each other and acting on the approach s ² of the lock opening / ³ L of the lever pulls the latter downwards, whereby the spring is compressed r.

Under these conditions, any further retraction of the barrel and breech is made impossible, the firing pin P can advance and the arm h ^{3 of} the loading bucket H presents its notch h ^{i to} the pusher arm j ^l .

If the weapon were not completely closed, for example as a result of incomplete indentation of the thumbs DD _1, then the lever L would not have pushed the lock s all the way down and the firing pin would still be held back, providing complete safety for the shooter. If the rifle is already completely closed, one acts on the trigger J to pull down the trigger point / 'and release the firing pin P which, under the action of its spring u, leaps forward and fires the cartridge.

In order to continue the leaning, one has to repeat the movements and handles already described in the following order: i. Oeffhen of the closure, the second inserting a cartridge into the hold, 3. depressing the lock button i \ 4. peeling.

b) As a repeating rifle. Assume that the magazine / is filled with cartridges and one cartridge is in the hold; one then only has to release the loading spoon H by unscrewing the lock h and pull it off.

Opening the rifle and ejecting the cartridge case is the same as with the single shot, only with the difference that that resulting from the explosion of the fired cartridge Back material causes the rifle to open.

The free loading spoon H , carrying a cartridge, rises (Fig. Generally dotted) as soon as the barrel has resumed its normal position; it is in this case come so high, the fresh cartridge DAF in the loading space can be inserted, so fast, the movable Verschlufsstück C, whose lock BEZW 2 by the movement of the loading bucket H. through whose arm /? ³ and paragraph i ^{2 was} automatically disengaged, pushes the cartridge into the barrel and at the same time pushes the spoon H down again by sliding on its surfaces h ² h " ^2. The rifle is now just as securely closed as if the lock was opened i disengages by hand, and the gun can be fired immediately, from which it can be seen that the shooter only has to press the tongue J one after the other in order to fire the shots until the magazine is emptied.

Since the rifle opens only after the rear end, i. H. as soon as the run goes on again, so it is understandable that on opening the gas pressure has completely disappeared in the course of the process and that there is neither an ejection of dirt, which adversely affects the cleanliness of the closure harm, nor gas losses are to be feared, which the performance of the rifle would affect.

The rapidity of ejecting the empty cartridge cases removes a large part that warmth, which with rifles of other systems has time to impart itself to the course, so that with the same cartridges and with the same number of shots the breech is heated with the rifle described above is significantly less than with all other known rifle systems.

Part of the return taken up by the springs is only transmitted through a slow pressure on the armpit of the shooter, so that the material effect of the same is almost zero; this weakening of the reverse material is particularly important when using of the weapon, by riders who only hold the rifle in one hand, of importance.

c) As a hunting rifle. The embodiment of the rifle necessary for this is provided by the Figures 10 through 13 of the accompanying drawings shown.

Here, the locking sleeve B and the movable locking piece C are constructed in the same way and work as described above, only the cartridge extractor e is replaced here by two laterally arranged hooks η η (Fig. 13) and the empty cartridge case is ejected by the fresh one from Loading spoon H fed cartridge, which, on the right

Claims (1)

Climbing up the side of the barrel, lifting the empty case and throwing it out, the rifle. In the present case, the closure housing has no opening for the introduction of the Cartridges in the magazine, but the latter is loaded from the front and contributes to this Purpose of a spring / sheath provided, which is screwed onto the magazine, as soon as the cartridges are inserted into the latter. As described earlier, the cartridges get into the loading spoon H, which no longer has a lock that makes it immobile. Instead of the latter, a device connected to the bracket S acts; the bracket is namely attached to an axis of rotation t , which carries a lever k , the angle piece k ¹ (see Fig. 11) is inserted into a hole provided in the loading spoon H as soon as the bracket is rotated by t; With the same turning movement of the handle, an attachment k " ^{2 is brought} under the trigger J , which makes the latter immobile and makes it impossible to fire the shot. The inserted cartridge hits the projection r ² attached to an axis ο , is lifted up by the loading spoon when the movable locking piece moves forward and pushed through the former into the loading space. The cartridge lock h ^% here does not form a part of the loading spoon, but an independent, resilient piece which is automatically pressed down by the spoon H in order to allow a cartridge to get into the latter. The lock i of the movable locking piece is actuated by the loading spoon, so that the button i ^{1 is} omitted; a spring r ¹ acts on i in order to constantly push the latter up into the locking piece C , while the raised spoon H tries to lower it so that the locking piece C can move forward. The mode of action of the hunting rifle is the same as that of the two above-described forms of leadership. Patent claims:
