DESCRIPTION OF THE PREFERRED EMBODIMENTS According to FIG. 1, the firearm 10 is in its rearmost position, for example under the action of the rear seat of a fired cartridge.
At this time, the rear seat spring (not shown) is compressed and the gun barrel 1 is compressed.
0 moves again to its forwardmost position according to FIGS. 2 and 3. The gun barrel 10 is fixed to a housing 11 which is movably mounted in a firearm housing 12. In this movable housing 11 there is a wedge closure 13. In FIGS. 1 and 2, this wedge-shaped closure 13 is shown in a lower position in which a cartridge 14 can be inserted into the gun barrel 10. In FIG. 3, the wedge-shaped closure device 13 is in the upper position, and the rear end of the gun barrel 10 is closed. Figure 1~
It is clear from FIG. 3 that movement of the wedge closure mechanism 13 can only take place when the cartridge 14 has been completely inserted into the gun barrel 10. 1st
A cartridge 14, whose rearmost position is shown in the figure, is inserted into the gun barrel 10 by an insertion device 15. This insertion device 15 is fixed in a movable housing 11 and has a carriage 16 with a projection 17.
has. A two-armed lever 18 is used for the movement of the carriage 16. This lever 18 is pivotably mounted on the housing 11 and has one arm extending into a slot 52 of the carriage 16. In the other arm the lever 18 has a roller 56;
The rollers are guided in control grooves 51 in the fixed position firearm housing 12. Depending on the shape of the control groove 51, the two-arm lever 18
is moved from the position according to FIG. 1 to the position according to FIGS. 2 and 3, and the carriage 16 is likewise moved to the first position.
It is moved from the position shown in the figure to the position according to FIGS. 2 and 3. The projection 17 of the carriage 16 then hits the bottom of the cartridge 14, so that the cartridge is accelerated and fed into the gun barrel 10. In FIG. 2, the cartridge 14 has only partially entered the gun barrel 10, while in FIG. 3, the cartridge has been completely pushed into the gun barrel 10. The carriage 16 is movably guided in a guide 19 of the movable housing 11.

According to FIG. 1, above the cartridge 14 there is a cartridge feeding device 20. This cartridge feeding device 20 has two star-shaped carriers 21 by which the cartridges 14 are fed laterally, ie transversely to the firing direction. Between the two star-shaped carriers 21 there is a transition body 22 along which the cartridge 14 is slid when the cartridge is pushed into the gun barrel 10 by the projection 17 of the carriage 16. The insertion device 15 and cartridge feeding device 20 are not the object of the present invention and will not be described in detail here.

Separate equipment is required to monitor whether the cartridge 14 has been inserted and whether it is completely in the gun barrel 10. These devices subsequently open the wedge closure 13 so that they can be moved into the closed position. These devices will be explained in detail based on FIG.

According to FIG. 4, a detection pin 2 is attached to the rear end of the gun barrel 10.
3, the detection pin is movable laterally with respect to the barrel axis and is supported on the shoulder 24 of the cartridge 14. This detection pin 23 is connected to the lever 2 of one arm at its upper end.
5, the lever of one arm is pivotably supported on the housing 11. A two-armed lever 26 is supported on this lever 25, and the lever 26 is pivotably supported on the firearm housing 12, which is fixed in position. This two-armed lever 26 is pivotable about an axis 27. The spring 28 causes the lever 26 to pivot counterclockwise and in doing so causes the lever 26 to move against the one-arm lever 25.
I will urge you to press on. The lever 26 has a fork 29 on one arm thereof and a pawl 31 on the fork.
The protrusion 30 engages. The pawl 31 is pivoted about an axis 32 on the stationary firearm housing 12 and serves for locking a carriage 33 which is movably guided in the firearm housing 12. The carriage 33 has a hole in which there is a spring 34, which on the one hand
3 and is supported on the firearm housing 12 in a manner not shown on the other hand. This spring biases the carriage 33 to move to the left in FIG. The carriage 33 also has a slot 35 in which the cartridge 14 is not inserted into the gun barrel 10 and therefore the pin 2
3 is not lifted, the pawl 31 engages.
A two-armed insertion lever 36 is supported on the carriage 33 so as to be pivotable about an axis 37. This insertion lever 36 has a roller 38 in one arm, which engages in a branched control groove 39 of the firearm housing 12. This lever 36 is
4 for complete insertion, the other arm 40 hitting the bottom of the cartridge 14. The control groove 39 has two switches 41 such that the lever 36 causes the roller 38 to alternately engage one or the other branch of the control groove 39 when the carriage 33 is put back and forth. This branch of the control groove 39 is for inserting the cartridge into the gun barrel during the forward movement of the carriage 33, so that upon the retraction of the carriage 33 the lever 36 is immediately pivoted and therefore the empty cartridge to be ejected is removed. This is necessary to prevent the cylinder from hitting the arm 40 of the lever 36. The switch 41 is constructed in a conventional manner and will therefore not be described in detail here. The arm 40 of the insertion lever 36 has a cam 42 which abuts against a blocking lock 43 by the insertion lever 36 during insertion of the cartridge 14. This blocking lock 43
is mounted pivotably about an axis 44 in a movable housing 11. A wedge-shaped closure 13, movable transversely with respect to the barrel axis, is supported on the lock 43 with a stop face 45 when the lock is in the position according to FIG. For the release of the wedge closure, the blocking lock 43 engages the cam 4 of the insertion lever 36.
2 must be rotated clockwise. A further two-armed lever 46 is pivotably mounted on the movable housing 11 about an axis 47 for pivoting the blocking lock 43 back into the blocking position according to FIG. This lever 46 is supported on a blocking lock 43 and is pivoted together with the blocking lock 43 from the position according to FIG. 4 to the position according to FIG. 3 when the cam 42 of the insertion lever 36 has fully inserted the cartridge 14. Lever 4 on the lower arm
6 has a pawl 48 which cooperates with a control cam 49 to pivot the lever 46 back into the position according to FIG. 4 when the wedge closure 13 is lowered. The blocking lock 43 is then also swiveled into its starting position according to FIG. 4, so that the wedge closure 13 is locked again. The lever 46 has a protrusion 53, and the protrusion
0 can be engaged in the discharging groove 54. Bullet 5
There are two release levers 46 on either side of the 0, but only one is shown in the figure. This double ejection lever 46
With this, an empty cartridge 50 can be ejected from the gun barrel 10 for each firing.

(Operation of the invention) The described device for inserting the ammunition cartridge 14 into the gun barrel 10, for monitoring the position of the cartridge inserted into the gun barrel and for controlling the wedge-shaped closure mechanism 13 of the firearm operates as follows. do.

After each firing, the gun barrel 10 is retracted under the action of the rear seat. By means of the rear seat of the gun barrel 10, the wedge closure 13 is opened, ie the wedge closure is moved from its uppermost position to its lowermost position. The lowering wedge-shaped closing machine 13 is controlled by the control cam 49 of the dispensing lever 46.
48, whereby the dispensing lever is pivoted into the position according to FIG. As a result, the empty cartridge 50 is ejected from the cartridge loading section 55 of the gun barrel 10, and the cam 53 is inserted into the ejecting groove 55 of the empty cartridge 50.
4. As soon as the empty cartridge 50 is ejected, the detection pin 23 is lowered, thereby causing the lever 2
Via 5, the lever 26 and the pawl 31 of the two arms are also pivoted into the position according to FIG. By means of the rear gun barrel 10, the carriage 31 is also returned to its starting position according to FIG. 4 together with the insertion lever 36. At that time, the roller 38
is lowered in the front branch of the control groove 39, during which the insertion lever 36 is swiveled counterclockwise into the position according to FIG. Reach out of orbit. The switch 41 is then actuated and the roller 38 is located at the branch of the control groove 39. As is clear from FIGS. 1 and 4, the carriage 33 is completely returned.
is held in this position by the pawl 31 when the empty cartridge 50 is ejected and the detection pin 23 releases the pawl 31. A carriage 16 is provided at the rear seat of the gun barrel 10 for loading a new cartridge.
is also returned to its rearmost position according to FIG. Furthermore, the next cartridge 14 is fed into the position according to FIG. 1 by means of a cartridge feeding device, which is not shown here. As can be seen in FIG. 1, the wedge closure 13 is held in its lowest position by the blocking pawl 43.

As soon as the gun barrel 10 reaches its rearmost position according to FIG. 1 by means of the rear seat, it is seated again by the rear seat spring (not shown) of the firearm. During this restoring of the gun barrel 10, the roller 56 of the lever 18 is also moved forward in the fixed control groove 51, so that the lever 18
is pivoted counterclockwise and the carriage 16 is moved forward by the projection 17. The protrusion 17 then abuts against the bottom of the cartridge 14, and the cartridge is inserted into the cartridge chamber 55 of the gun barrel 10 (FIG. 3). According to FIG. 2, the cartridge 14 inserted into the gun barrel 10 abuts the detection pin 23 with its shoulder 24. As a result, the detection pin 23 is lifted up, and the claw 3 is moved through the lever 25 and the lever 26 of the two arms.
1 is activated and the carriage 33 is released.
According to FIG. 4, the carriage 33 is moved by the spring 34 to its forwardmost position (FIG. 3). At this time, the roller 38 of the two-arm insertion lever 36 is inserted into the guide groove 39.
is moved upwardly in the rear branch of the gun, and the insertion lever 36 can insert the cartridge 14 completely into the gun barrel 10 from the position according to FIG. 2, ie into the position according to FIG. 3. The roller 38 then again activates the switch 41 (FIG. 4) and reaches the front branch of the guide groove 39. The insertion lever 36 also abuts the blocking lock 43 during insertion of the cartridge 14, so that the blocking lock is simultaneously pivoted clockwise and releases the wedge closure 13. The wedge closure 13 is then moved upwards by the lever 57, thereby closing the gun barrel 10. Only when the blocking lock 43 is pivoted by means of the insertion lever 36 can the wedge closure 13 be moved, so that the cartridge 14 is completely inserted into the cartridge chamber 55 of the gun barrel 10.
This ensures that the wedge closure 13 is only moved upwards when inserted therein.
