Definitions

  • the invention relates to a device for feeding cartridges from a stationary ammunition container to a firearm, according to the preamble of claim 1.
  • This cartridge feeder is particularly useful for third-party firearms, e.g. suitable for Gatling cannons.
  • a Gatling cannon is known to have a rotating tube bundle. With such a weapon, the run-up of the weapon to full cadence leads to a large spread, so the first shot should only be fired when the tube bundle has reached its target speed, i.e. no firing should take place during the so-called run-up.
  • the device for feeding cartridges in turn takes a certain amount of time until it has reached the full feeding speed. Furthermore, this cartridge feeder should be able to feed two different types of ammunition.
  • a memory is provided in a known cartridge supply device of this type (EP-A-0 020 095).
  • a transport chain is passed through a feed channel, through a storage channel and through a return channel.
  • the feed channel opens into a firearm transfer station.
  • a switch is located at the transition point from the feed channel to the storage channel. When this switch is in position, the ammunition passes from the feed channel to a further feed system with a second transport chain, which leads to the firearm transfer station. In the other position of this switch, the ammunition on the transport chain passes through the storage channel into the return channel. Through a switch that is connected to the weapon the points are switched from their first position to their second position. The feed system continues to rotate until all cartridges have been removed. The first transport chain continues to move and brings the ammunition into the storage channel.
  • a reversing device then moves the first transport chain backwards until the ammunition has returned from the storage channel to the feed channel. The ammunition is then returned to the weapon for the next round of fire.
  • This known device is intended to prevent individual cartridges from remaining in the barrel of the firearm after a series fire, which can then lead to malfunctions. However, this device is not able to feed the first cartridge of the firearm only after the start-up has ended.
  • the object which is solved by the features listed in claim 1, is to provide a cartridge feeder which is able to feed the firearm the first cartridge only when the firearm has started up and at the same time the full feed speed has been reached, whereby After each series fire, the starting position can be created quickly and safely.
  • the advantage of the device is that not only the ramp-up of the weapon, but also the ramp-up time of the Feeding device can be taken into account and adapted exactly.
  • At least two types of ammunition can also be supplied in order to selectively use cartridges from one or a second stationary ammunition container.
  • a turret 10 is rotatably mounted on a ship deck 11 or a vehicle platform 11.
  • two Gatling guns 12 and 13 are pivotably mounted about an elevation axis 14 in this turret. According to FIG. 1, these Gatling guns 12 and 13 can be raised from the horizontal position shown in solid lines to different positions, for example they can be lowered by 30 ° into position 12a or raised by 42.5 ° into position 12b or into the position Position 12c can be raised by 115 °.
  • Each of the two Gatling cannons 12 and 13 has seven weapon barrels 15, as can be seen from FIG. Below that Gatling guns 12 and 13 have three containers 16, 17, 18 and 19, 20, 21 for each weapon, as can be seen in particular from FIG.
  • the two middle containers 17 and 20 serve to hold the empty cartridge cases.
  • a channel leads from each container 16-21 to one of the two weapons 12 and 13.
  • These six channels 16a-21a are best seen in FIG.
  • One type of cartridge is supplied to weapons 12 and 13 in channels 16a and 19a
  • the other type of cartridge is supplied to weapons 12 and 13 in channels 18a and 21a.
  • the empty cartridge cases of both types pass through the channels 17a and 20a into the middle containers 17 and 20.
  • Each three channels 16a-18a and 19a-21a open into a common housing 22 and 23.
  • a first elastic channel leads from the housing 22 24 to the first cannon 12 and from the second housing 23 a second elastic channel 25 leads to the second cannon 13.
  • FIG. 2 there are endless chains 16b and 19b in the channels 16a and 19a with which the cartridges from the containers 16 and 19 to can be transported into the housing 22 or 23.
  • FIG. 4 there are also endless chains 24a and 25a in the elastic or flexible channels 24 and 25, with which the cartridges are fed from the housing 22 and 23 to the weapon 12 and 13, respectively.
  • Endless chains 16c and 19c are also arranged in the containers 16 and 19, in which the cartridges are stored on the one hand and with which the cartridges are transported up to the endless chains 16b and 19b.
  • FIG. 1 The transfer of the cartridges from the endless chains 16b and 18b to the common endless chain 24a can be seen in FIG.
  • Two transfer wheels 26a and 26b are arranged between the endless chain 16b and the endless chain 24a and two further transfer wheels 27a and 27b are arranged between the endless chain 18b and the endless chain 24a.
  • a first switch 28 enables the cartridges to be transferred from the endless chain 16b to the first transfer wheel 26a when this switch 28 is in its first position. In the other position of this switch 28, the cartridges remain on the endless chain 16b and come back against the container 16 (FIG. 5).
  • a second switch 29 enables the cartridges to be transferred from the endless chain 18b to the third transfer wheel 27a when this switch 29 is in its first position.
  • This switch 28 and 29 contains two deflection segments 30 and 31, of which one or the other segment 30 or 31 can be effective. If the deflection segment 30 of the switch 28 is effective, the cartridges 32 pass from the endless chain 16b onto the transfer wheel 26a. If the other deflection segment 31 of the switch 28 is effective, the cartridges 32 remain on the endless chain 16b. The same applies to the two deflection segments 30 and 31 of the second switch 29.
  • a third switch 42 is also arranged between the two transfer wheels 26b and 27b and the first endless chain 24a.
  • the four channels 16a, 18a, 19a and 21a preferably each have a sensor 50 or 51, the position of which determines the starting position of the sensor first cartridge 32 to be supplied to the weapon 12, 13.
  • Both the endless chain 16b and the endless chain 18b are each guided over a deflection wheel 33 or 34.
  • the deflection wheel 33 of the endless chain 16b is in drive connection via two gear wheels 43 and 44 (FIG. 6a) with the transfer wheel 26a and the deflection wheel 34 of the endless chain 18b is in drive connection with the transfer wheel 27a via two gear wheels 45 and 46.
  • the endless chain 24a is guided over a deflection wheel 39.
  • This deflection wheel 39 of the endless chain 24a is in drive connection with the transfer wheel 26b via two toothed wheels 49 and 47, and furthermore this deflection wheel 39 of the endless chain 24a is connected with the transfer wheel 27b via two toothed wheels 49 and 48.
  • the gears 44 and 47 are in engagement with one another via a clutch 35 (see FIG. 8) and likewise the gears 45 and 46 are in engagement with one another via a clutch 36. If the clutch 35 is switched on, cartridges 32 can be fed from the endless chain 16b via the transfer wheels 26a and 26b to the endless chain 24a. If the other clutch 36 is switched on, cartridges 32 can be fed from the other endless chain 18b to the endless chain 24a via the transfer wheels 27a and 27b. Thus, either cartridges 32 from the container 16 get to the firearm 12, or when the other clutch 36 is switched on, cartridges 32 get from the other container 18 to the firearm 12.
  • These couplings 35 and 36 thus make it possible to selectively switch from one type of ammunition to one different types of ammunition and therefore form the means for switching to selectively feed cartridges from one or the other ammunition container 16, 18 or 19, 21 to the firearm 12 or 13.
  • the switches 28 and 29, on the other hand make it possible to determine from which container the first cartridge 32 of the weapon 12 is to be fed and at what point in time the supply of the cartridges 32 to the weapon 12 is to be interrupted.

Description

Die Erfindung betrifft eine Vorrichtung zum Zuführen von Patronen aus einem ortsfesten Munitionsbehälter zu einer Feuerwaffe, gemäss dem Oberbegriff des Anspruches 1.The invention relates to a device for feeding cartridges from a stationary ammunition container to a firearm, according to the preamble of claim 1.

Diese Patronenzuführvorrichtung ist insbesondere für Feuerwaffen mit Fremdantrieb, z.B. für Gatlingkanonen, geeignet. Eine Gatlingkanone besitzt bekanntlich ein rotierendes Rohrbündel. Bei einer solchen Waffe führt der Hochlauf der Waffe bis zur vollen Kadenz zu grosser Streuung, daher soll der erste Schuss erst abgefeuert werden, wenn das Rohrbündel seine Solldrehzahl erreicht hat, d.h. während des sogenannten Hochlaufes soll nicht gefeuert werden. Die Vorrichtung zum Zuführen von Patronen benötigt ihrerseits eine gewisse Zeit, bis sie die volle Zuführgeschwindigkeit erreicht hat. Ferner sollte diese Patronenzuführvorrichtung in der Lage sein, zwei verschiedene Sorten von Munition zuzuführen.This cartridge feeder is particularly useful for third-party firearms, e.g. suitable for Gatling cannons. A Gatling cannon is known to have a rotating tube bundle. With such a weapon, the run-up of the weapon to full cadence leads to a large spread, so the first shot should only be fired when the tube bundle has reached its target speed, i.e. no firing should take place during the so-called run-up. The device for feeding cartridges in turn takes a certain amount of time until it has reached the full feeding speed. Furthermore, this cartridge feeder should be able to feed two different types of ammunition.

Bei einer bekannten Patronenzuführvorrichtung dieser Art (EP-A-0 020 095) ist ein Speicher vorhanden. Eine Transportkette wird durch einen Zuführkanal, durch einen Speicherkanal und durch einen Rückführkanal hindurchgeführt. Der Zuführkanal mündet in eine Übergabestation der Feuerwaffe. An der Übergangsstelle vom Zuführkanal zum Speicherkanal befindet sich eine Weiche. In einer Stellung dieser Weiche gelangt die Munition aus dem Zuführkanal auf ein weiteres Zuführsystem mit einer zweiten Transportkette, welche zur Übergabestation der Feuerwaffe führt. In der anderen Stellung dieser Weiche gelangt die Munition auf der Transportkette durch den Speicherkanal in den Rückführkanal. Durch einen Schalter, der mit der Waffe verbunden ist, kann die Weiche umgeschaltet werden von ihrer ersten Stellung in ihre zweite Stellung. Das Zuführsystem dreht sich weiter vorwärts, bis alle Patronen daraus entfernt wurden. Die erste Transportkette bewegt sich weiter vorwärts und bringt die Munition in den Speicherkanal. Eine Umkehrvorrichtung bewegt anschliessend die erste Transportkette rückwärts, bis die Munition aus dem Speicherkanal wieder in den Zuführkanal gelangt ist. Anschliessend wird die Munition wieder für den nächsten Feuerstoss unmittelbar der Waffe zugeführt. Diese bekannte Vorrichtung soll verhindern, dass nach einem Seriefeuer einzelne Patronen in den Rohrkammern der Feuerwaffe verbleiben, die dann zu Störungen führen können. Diese Vorrichtung ist jedoch nicht in der Lage, die erste Patrone der Feuerwaffe erst nach Beendigung des Hochlaufes zuzuführen.A memory is provided in a known cartridge supply device of this type (EP-A-0 020 095). A transport chain is passed through a feed channel, through a storage channel and through a return channel. The feed channel opens into a firearm transfer station. A switch is located at the transition point from the feed channel to the storage channel. When this switch is in position, the ammunition passes from the feed channel to a further feed system with a second transport chain, which leads to the firearm transfer station. In the other position of this switch, the ammunition on the transport chain passes through the storage channel into the return channel. Through a switch that is connected to the weapon the points are switched from their first position to their second position. The feed system continues to rotate until all cartridges have been removed. The first transport chain continues to move and brings the ammunition into the storage channel. A reversing device then moves the first transport chain backwards until the ammunition has returned from the storage channel to the feed channel. The ammunition is then returned to the weapon for the next round of fire. This known device is intended to prevent individual cartridges from remaining in the barrel of the firearm after a series fire, which can then lead to malfunctions. However, this device is not able to feed the first cartridge of the firearm only after the start-up has ended.

Aus der US-A-4,836,082 ist ferner bekannt, dass bei einer Mehrrohrkanone (cloud gun) während des Hochlaufs der Waffe die Patronenzufuhr nicht aktiviert ist. Erst bei einem anschliessenden erwünschten Feuerbefehl werden die Antriebe für die Patronenzuführungen freigegeben. Nachteilig ist dabei, dass die Mehrrohrkanone in Rotation gehalten werden muss für die Erstellung der Feuerbereitschaft und die Hochlaufzeit der Patronenzuführung unberücksichtigt bleibt.From US-A-4,836,082 it is also known that in the case of a multi-barrel cannon (cloud gun) the cartridge feed is not activated during the run-up of the weapon. The drives for the cartridge feeds are only released when a subsequent fire command is requested. The disadvantage here is that the multi-tube cannon must be kept in rotation for the preparation of the fire readiness and the ramp-up time of the cartridge feed is not taken into account.

Die Aufgabe, welche durch die im Anspruch 1 aufgeführten Merkmale gelöst ist, besteht in der Schaffung einer Patronenzuführvorrichtung, welche in der Lage ist, der Feuerwaffe die erste Patrone erst zuzuführen, wenn der Hochlauf der Feuerwaffe beendet und gleichzeitig die volle Zuführgeschwindigkeit erreicht sind, wobei nach jedem Seriefeuer die Ausgangslage schnell und sicher zu erstellen ist.The object, which is solved by the features listed in claim 1, is to provide a cartridge feeder which is able to feed the firearm the first cartridge only when the firearm has started up and at the same time the full feed speed has been reached, whereby After each series fire, the starting position can be created quickly and safely.

Der Vorteil der Vorrichtung besteht darin, dass nicht nur der Hochlauf der Waffe, sondern auch die Hochlaufzeit der Zuführvorrichtung berücksichtigt und exakt angepasst werden kann.The advantage of the device is that not only the ramp-up of the weapon, but also the ramp-up time of the Feeding device can be taken into account and adapted exactly.

Vorzugsweise können auch mindestens zwei Sorten Munition zugeführt werden, um wahlweise Patronen aus dem einen oder einem zweiten ortsfesten Munitionsbehälter zu verwenden.Preferably, at least two types of ammunition can also be supplied in order to selectively use cartridges from one or a second stationary ammunition container.

Ein Ausführungsbeispiel der erfindungsgemässen Vorrichtung zum Zuführen von Patronen aus einem ortsfesten Munitionsbehälter zu einer Feuerwaffe ist im folgenden anhand der beigefügten Zeichnung ausführlich beschrieben. Es zeigt:

Gemäss Fig.1 ist ein Geschützturm 10 auf einem Schiffsdeck 11 oder einer Fahrzeugplattform 11 drehbar gelagert. In diesem Geschützturm sind gemäss Fig.1 und 2 zwei Gatlingkanonen 12 und 13 um eine Elevationsachse 14 schwenkbar gelagert. Gemäss Fig.1 können diese Gatlingkanonen 12 und 13 aus der horizontalen, mit ausgezogenen Strichen dargestellten Lage in verschiedene Stellungen eleviert werden, z.B. können sie in die Stellung 12a um 30° gesenkt oder in die Stellung 12b um 42,5° angehoben oder in die Stellung 12c um 115° angehoben werden. Jede der beiden Gatlingkanonen 12 und 13 besitzt sieben Waffenrohre 15, wie aus Fig.2 ersichtlich ist. Unterhalb den Gatlingkanonen 12 und 13 befinden sich für jede Waffe drei Behälter 16,17,18 bzw. 19,20,21, wie insbesondere aus Fig.3 ersichtlich ist. Die Behälter 16 und 19, die sich in Schussrichtung gesehen vorne befinden, enthalten eine erste Sorte Munition und die Behälter 18 und 21, die sich in Schussrichtung gesehen hinten befinden, enthalten eine zweite Sorte Munition. Die beiden mittleren Behälter 17 und 20 dienen zur Aufnahme der leeren Patronenhülsen. Von jedem Behälter 16-21 führt ein Kanal zu einer der beiden Waffen 12 und 13. Diese sechs Kanäle 16a-21a sind am besten aus Fig.5 ersichtlich. In den Kanälen 16a und 19a wird die eine Patronensorte den Waffen 12 und 13 zugeführt, in den Kanälen 18a und 21a wird die andere Patronensorte den Waffen 12 und 13 zugeführt. Durch die Kanäle 17a und 20a gelangen erfindungsgemäss die leeren Patronenhülsen beider Sorten in die mittleren Behälter 17 und 20. Je drei Kanäle 16a-18a bzw. 19a-21a münden in ein gemeinsames Gehäuse 22 bzw. 23. Vom Gehäuse 22 führt ein erster elastischer Kanal 24 zur ersten Kanone 12 und vom zweiten Gehäuse 23 führt ein zweiter elastischer Kanal 25 zur zweiten Kanone 13. Gemäss Fig.2 befinden sich in den Kanälen 16a und 19a Endlosketten 16b und 19b, mit denen die Patronen aus den Behältern 16 bzw. 19 bis in das Gehäuse 22 bzw. 23 transportiert werden. Gemäss Fig.4 befinden sich in den elastischen oder flexiblen Kanälen 24 bzw. 25 ebenfalls Endlosketten 24a und 25a, mit denen die Patronen aus dem Gehäuse 22 bzw. 23 der Waffe 12 bzw. 13 zugeführt werden. In den Behältern 16 und 19 sind ebenfalls Endlosketten 16c bzw. 19c angeordnet, in welchen die Patronen einerseits gespeichert sind und mit denen die Patronen bis zu den Endlosketten 16b bzw. 19b transportiert werden. Genauso befinden sich auch in den beiden Behältern 18 und 21 Endlosketten, die jedoch in den Zeichnungen nicht dargestellt sind. Ebenso befinden sich auch in den Kanälen 18a und 21a Endlosketten 18b, 21b, welche jedoch in den Zeichnungen ebenfalls nicht dargestellt sind.1, a turret 10 is rotatably mounted on a ship deck 11 or a vehicle platform 11. 1 and 2, two Gatling guns 12 and 13 are pivotably mounted about an elevation axis 14 in this turret. According to FIG. 1, these Gatling guns 12 and 13 can be raised from the horizontal position shown in solid lines to different positions, for example they can be lowered by 30 ° into position 12a or raised by 42.5 ° into position 12b or into the position Position 12c can be raised by 115 °. Each of the two Gatling cannons 12 and 13 has seven weapon barrels 15, as can be seen from FIG. Below that Gatling guns 12 and 13 have three containers 16, 17, 18 and 19, 20, 21 for each weapon, as can be seen in particular from FIG. Containers 16 and 19, which are at the front in the firing direction, contain a first type of ammunition and the containers 18 and 21, which are at the rear in the firing direction, contain a second type of ammunition. The two middle containers 17 and 20 serve to hold the empty cartridge cases. A channel leads from each container 16-21 to one of the two weapons 12 and 13. These six channels 16a-21a are best seen in FIG. One type of cartridge is supplied to weapons 12 and 13 in channels 16a and 19a, the other type of cartridge is supplied to weapons 12 and 13 in channels 18a and 21a. According to the invention, the empty cartridge cases of both types pass through the channels 17a and 20a into the middle containers 17 and 20. Each three channels 16a-18a and 19a-21a open into a common housing 22 and 23. A first elastic channel leads from the housing 22 24 to the first cannon 12 and from the second housing 23 a second elastic channel 25 leads to the second cannon 13. According to FIG. 2 there are endless chains 16b and 19b in the channels 16a and 19a with which the cartridges from the containers 16 and 19 to can be transported into the housing 22 or 23. According to FIG. 4, there are also endless chains 24a and 25a in the elastic or flexible channels 24 and 25, with which the cartridges are fed from the housing 22 and 23 to the weapon 12 and 13, respectively. Endless chains 16c and 19c are also arranged in the containers 16 and 19, in which the cartridges are stored on the one hand and with which the cartridges are transported up to the endless chains 16b and 19b. Likewise, there are endless chains in the two containers 18 and 21, but these are not shown in the drawings. There are also endless chains 18b, 21b in the channels 18a and 21a, which, however, are also not shown in the drawings.

Die Übergabe der Patronen von den Endlosketten 16b bzw. 18b an die gemeinsame Endloskette 24a ist aus Fig.6 ersichtlich. Zwischen der Endloskette 16b und der Endloskette 24a sind zwei Übergaberäder 26a und 26b angeordnet und zwischen der Endloskette 18b und der Endloskette 24a sind zwei weitere Übergaberäder 27a und 27b angeordnet. Eine erste Weiche 28 ermöglicht die Übergabe der Patronen von der Endloskette 16b auf das erste Übergaberad 26a, wenn sich diese Weiche 28 in ihrer ersten Stellung befindet. In der anderen Stellung dieser Weiche 28 bleiben die Patronen auf der Endloskette 16b und gelangen wieder zurück gegen den Behälter 16 (Fig.5). Eine zweite Weiche 29 ermöglicht die Übergabe der Patronen von der Endloskette 18b auf das dritte Übergaberad 27a, wenn sich diese Weiche 29 in ihrer ersten Stellung befindet. In der anderen Stellung dieser Weiche 29 bleiben die Patronen 32 auf der Endloskette 18b und gelangen wieder zurück gegen den Behälter 18. Die Ausbildung dieser Weichen 28 und 29 wird hier als bekannt vorausgesetzt und es wird auf die Europäische Patentschrift Nr. 0 184 008 hingewiesen. Diese Weiche 28 bzw. 29 enthält zwei Umlenksegmente 30 und 31, von denen wahlweise das eine oder andere Segment 30 oder 31 wirksam sein kann. Falls das Umlenksegment 30 der Weiche 28 wirksam ist, gelangen die Patronen 32 von der Endloskette 16b auf das Übergaberad 26a. Falls das andere Umlenksegment 31 der Weiche 28 wirksam ist, bleiben die Patronen 32 auf der Endloskette 16b. Das gleiche gilt für die beiden Umlenksegmente 30 und 31 der zweiten Weiche 29. Zwischen den beiden Übergaberädern 26b und 27b und der ersten Endloskette 24a ist noch eine dritte Weiche 42 angeordnet. In der gezeigten Stellung dieser Weiche 42 ist das Umlenksegment 31 wirksam und die Patronen 32 gelangen vom Umlenkrad 26b auf die Endloskette 24a. Beim Umschalten der Weiche 42 ist das andere Umlenksegment 30 wirksam und die Patronen 32 gelangen vom Umlenkrad 27b auf die Endloskette 24a. Vorzugsweise weisen die vier Kanäle 16a, 18a, 19a und 21a je einen Sensor 50 oder 51 auf, durch dessen Lage die Ausgangslage der ersten der Waffe 12,13 zuzuführenden Patrone 32 bestimmt ist.The transfer of the cartridges from the endless chains 16b and 18b to the common endless chain 24a can be seen in FIG. Two transfer wheels 26a and 26b are arranged between the endless chain 16b and the endless chain 24a and two further transfer wheels 27a and 27b are arranged between the endless chain 18b and the endless chain 24a. A first switch 28 enables the cartridges to be transferred from the endless chain 16b to the first transfer wheel 26a when this switch 28 is in its first position. In the other position of this switch 28, the cartridges remain on the endless chain 16b and come back against the container 16 (FIG. 5). A second switch 29 enables the cartridges to be transferred from the endless chain 18b to the third transfer wheel 27a when this switch 29 is in its first position. In the other position of this switch 29, the cartridges 32 remain on the endless chain 18b and come back against the container 18. The formation of these switches 28 and 29 is assumed to be known here and reference is made to European Patent No. 0 184 008. This switch 28 and 29 contains two deflection segments 30 and 31, of which one or the other segment 30 or 31 can be effective. If the deflection segment 30 of the switch 28 is effective, the cartridges 32 pass from the endless chain 16b onto the transfer wheel 26a. If the other deflection segment 31 of the switch 28 is effective, the cartridges 32 remain on the endless chain 16b. The same applies to the two deflection segments 30 and 31 of the second switch 29. A third switch 42 is also arranged between the two transfer wheels 26b and 27b and the first endless chain 24a. In the position of this switch 42 shown, the deflection segment 31 is effective and the cartridges 32 pass from the deflection wheel 26b to the endless chain 24a. When the switch 42 is switched over, the other deflection segment 30 is effective and the cartridges 32 pass from the deflection wheel 27b onto the endless chain 24a. The four channels 16a, 18a, 19a and 21a preferably each have a sensor 50 or 51, the position of which determines the starting position of the sensor first cartridge 32 to be supplied to the weapon 12, 13.

Sowohl die Endloskette 16b als auch die Endloskette 18b sind über je ein Umlenkrad 33 bzw. 34 geführt. Das Umlenkrad 33 der Endloskette 16b steht über zwei Zahnrädern 43 und 44 (Fig.6a) mit dem Übergaberad 26a in Antriebsverbindung und das Umlenkrad 34 der Endloskette 18b steht über zwei Zahnrädern 45 und 46 mit dem Übergaberad 27a in Antriebsverbindung. Die Endloskette 24a ist über ein Umlenkrad 39 geführt. Dieses Umlenkrad 39 der Endloskette 24a steht über zwei Zahnräder 49 und 47 mit dem Übergaberad 26b in Antriebsverbindung und ferner steht dieses Umlenkrad 39 der Endloskette 24a über zwei Zahnräder 49 und 48 mit dem Übergaberad 27b in Verbindung. Die Zahnräder 44 und 47 stehen über eine Kupplung 35 miteinander in Eingriff (siehe Fig.8) und ebenso stehen die Zahnräder 45 und 46 über eine Kupplung 36 miteinander in Eingriff. Falls die Kupplung 35 eingeschaltet wird, können Patronen 32 von der Endloskette 16b über die Übergaberäder 26a und 26b der Endloskette 24a zugeführt werden. Falls die andere Kupplung 36 eingeschaltet wird, können Patronen 32 von der anderen Endloskette 18b über die Übergaberäder 27a und 27b der Endloskette 24a zugeführt werden. Somit gelangen entweder Patronen 32 aus dem Behälter 16 zur Feuerwaffe 12, oder wenn die andere Kupplung 36 eingeschaltet wird, gelangen Patronen 32 aus dem anderen Behälter 18 zur Feuerwaffe 12. Diese Kupplungen 35 und 36 ermöglichen somit das wahlweise Umschalten von einer Sorte Munition auf eine andere Sorte Munition und bilden daher die Mittel zum Umschalten, um wahlweise Patronen aus dem einen oder anderen Munitionsbehälter 16,18 bzw. 19,21 der Feuerwaffe 12 bzw. 13 zuzuführen. Die Weichen 28 und 29 ermöglichen dagegen, zu bestimmen, aus welchem Behälter die erste Patrone 32 der Waffe 12 zugeführt werden soll und zu welchem Zeitpunkt die Zufuhr der Patronen 32 zur Waffe 12 unterbrochen werden soll.Both the endless chain 16b and the endless chain 18b are each guided over a deflection wheel 33 or 34. The deflection wheel 33 of the endless chain 16b is in drive connection via two gear wheels 43 and 44 (FIG. 6a) with the transfer wheel 26a and the deflection wheel 34 of the endless chain 18b is in drive connection with the transfer wheel 27a via two gear wheels 45 and 46. The endless chain 24a is guided over a deflection wheel 39. This deflection wheel 39 of the endless chain 24a is in drive connection with the transfer wheel 26b via two toothed wheels 49 and 47, and furthermore this deflection wheel 39 of the endless chain 24a is connected with the transfer wheel 27b via two toothed wheels 49 and 48. The gears 44 and 47 are in engagement with one another via a clutch 35 (see FIG. 8) and likewise the gears 45 and 46 are in engagement with one another via a clutch 36. If the clutch 35 is switched on, cartridges 32 can be fed from the endless chain 16b via the transfer wheels 26a and 26b to the endless chain 24a. If the other clutch 36 is switched on, cartridges 32 can be fed from the other endless chain 18b to the endless chain 24a via the transfer wheels 27a and 27b. Thus, either cartridges 32 from the container 16 get to the firearm 12, or when the other clutch 36 is switched on, cartridges 32 get from the other container 18 to the firearm 12. These couplings 35 and 36 thus make it possible to selectively switch from one type of ammunition to one different types of ammunition and therefore form the means for switching to selectively feed cartridges from one or the other ammunition container 16, 18 or 19, 21 to the firearm 12 or 13. The switches 28 and 29, on the other hand, make it possible to determine from which container the first cartridge 32 of the weapon 12 is to be fed and at what point in time the supply of the cartridges 32 to the weapon 12 is to be interrupted.

Gemäss Fig.6b befindet sich hinter dem Zahnrad 44 noch ein zweites genau gleich grosses Zahnrad 52, von denen das eine Zahnrad 44 mit dem nächsten Zahnrad 47 ständig in Eingriff steht und von denen das andere Zahnrad 52 mit dem benachbarten Zahnrad 43 ständig in Eingriff steht. Die beiden auf der selben Achse hintereinander angeordneten Zahnräder 44 und 52 sind über die erwähnte Kupplung 35 miteinander verbindbar. Diese Kupplung 35 besteht aus zwei Kupplungshälften 53,54, die sich hydraulisch durch axiale Verschiebung in Eingriff bringen lassen und die unter der Kraft einer Feder 55 ausser Eingriff gelangen. Die Kupplung 36 (Fig.8) ist genau gleich ausgebildet und ist daher hier nicht beschrieben.According to FIG. 6b, behind the gear 44 there is a second gear 52 of exactly the same size, of which one gear 44 is constantly in engagement with the next gear 47 and of which the other gear 52 is in constant engagement with the adjacent gear 43 . The two gearwheels 44 and 52 arranged one behind the other on the same axis can be connected to one another via the coupling 35 mentioned. This coupling 35 consists of two coupling halves 53, 54 which can be brought into engagement hydraulically by axial displacement and which disengage under the force of a spring 55. The coupling 36 (FIG. 8) is of exactly the same design and is therefore not described here.

Gemäss Fig.7 dauert es nach dem Einschalten des Waffenantriebes beispielsweise 0,5 sec. bis die Kadenz von 5000 Schuss pro Minute erreicht ist, d.h. bis das Waffenrohrbündel sich mit der dieser Kadenz entsprechenden Tourenzahl dreht und der erste Schuss abgefeuert werden kann. Je nach Länge des Feuerstosses wird nach 0,1-2,0 sec. der letzte Schuss abgefeuert. Das Abbremsen des Waffenrohrbündels erfolgt in der halben Zeit im Vergleich zum Hochlauf. Die Kupplung 35 oder 36 wird jedoch schon vorher ausgeschaltet, und zwar aus folgendem Grunde: Gleichzeitig mit dem Waffenantrieb ist auch die Kupplung 35 oder 36 eingeschaltet worden. Da jedoch die erste Endloskette 24a oder 25a beim Einschalten der Kanone keine Patronen enthält, dauert es eine Weile, bis die erste Patrone 32 die Feuerwaffe erreicht. Die Länge dieser ersten Endloskette 24a oder 25a ist derart gewählt, dass gleichzeitig mit Erreichen der erforderlichen Kadenz der Waffe die erste Patrone 32 diese Waffe erreicht. Die Kupplung 35 oder 36 muss rechtzeitig vor Abschluss des Feuerstosses ausgeschaltet werden, damit die in der ersten Endloskette 24a oder 25a noch vorhandenen Patronen verschossen werden können, ohne dass aus der zweiten oder dritten Endloskette 16b,19b oder 18b,21b Patronen 32 zugeführt werden, derart, dass nach Beendigung des Feuerstosses die erste Endloskette 24a oder 25a wieder leer ist.According to FIG. 7 it takes, for example, 0.5 seconds after switching on the weapon drive until the cadence of 5000 rounds per minute is reached, ie until the weapon barrel bundle rotates with the number of revolutions corresponding to this cadence and the first shot can be fired. Depending on the length of the burst of fire, the last shot is fired after 0.1-2.0 seconds. The bundle of arms is braked in half the time compared to the run-up. However, the clutch 35 or 36 is switched off beforehand, for the following reason: The clutch 35 or 36 has also been switched on at the same time as the weapon drive. However, since the first endless chain 24a or 25a contains no cartridges when the gun is turned on, it takes a while for the first cartridge 32 to reach the firearm. The length of this first endless chain 24a or 25a is selected such that the first cartridge 32 reaches this weapon at the same time as the required cadence of the weapon is reached. The clutch 35 or 36 must be switched off in good time before the firing is completed so that the cartridges still present in the first endless chain 24a or 25a can be fired without cartridges 32 from the second or third endless chain 16b, 19b or 18b, 21b are fed in such a way that after the end of the burst of fire the first endless chain 24a or 25a is empty again.

Aus Fig.7 ist ferner ersichtlich, dass mit der zweiten Munitionssorte bereits nach 1,15 sec. wieder ein erster Schuss abgefeuert werden kann, dass hingegen mit der gleichen Munitionssorte erst wieder nach 2,15 sec. Unterbruch ein erster Schuss des nächsten Feuerstosses abgefeuert werden kann. Der Grund dafür ist, dass beim Einschalten der Kupplung 36 für die andere Munitionssorte und beim Umschalten der Weiche 29 0,4 sec. erforderlich sind bis die Waffe wieder feuerbereit ist, dass hingegen vor dem Einschalten der Kupplung 35 für die erste Munitionssorte zuerst eine Sekunde benötigt wird, bis die Patronenzuführvorrichtung der entsprechenden Endloskette wieder bereit ist.From Fig. 7 it can also be seen that with the second type of ammunition a first shot can be fired again after only 1.15 seconds, but that with the same type of ammunition a first shot of the next round of fire is only fired again after an interruption of 2.15 seconds can be. The reason for this is that when the clutch 36 is switched on for the other type of ammunition and when the switch 29 is switched over, 0.4 seconds are required until the weapon is ready to fire again, that is, however, before the clutch 35 is switched on for the first type of ammunition, first for a second is required until the cartridge feeder of the corresponding endless chain is ready again.

Gemäss Fig.8 werden die Feuerwaffe 12 bzw. 13 und die erste Endloskette 24a bzw. 25a von einem Motor 37 angetrieben. Eine Kanonenweiche 38 ermöglicht, die Zufuhr von Patronen 32 zur Waffe 12,13 zu unterbrechen. Wenn diese Weiche 38 eingeschaltet ist, gelangen die Patronen von der Endloskette 24a,25a zur Waffe 12,13. Sobald die Weiche 38 ausgeschaltet wird, beispielsweise bei "hang fire", gelangen die Patronen nicht mehr zur Waffe 12,13, sondern werden durch die Endloskette 24a,25a wieder zurücktransportiert. Diese erste Endloskette 24a,25a ist über zwei Umlenkrollen 39 geführt und geht durch den flexiblen Kanal 24,25 hindurch. Vom ersten Munitionsbehälter 16,19 führt die zweite Endloskette 16b,19b zur ersten Endloskette 24a,25a. Vom zweiten Munitionsbehälter 18,21 führt die dritte Endloskette 18b,21b zur ersten Endloskette 24a,25a. Über die eine Kupplung 35 können die erste Endloskette 24a,25a und die zweite Endloskette 16b,19b miteinander gekuppelt werden. Über die andere Kupplung 36 können die erste Endloskette 24a,25a und die dritte Endloskette 18b,21b miteinander gekuppelt werden.8, the firearm 12 and 13 and the first endless chain 24a and 25a are driven by a motor 37. A cannon switch 38 makes it possible to interrupt the supply of cartridges 32 to the weapon 12, 13. When this switch 38 is switched on, the cartridges pass from the endless chain 24a, 25a to the weapon 12, 13. As soon as the switch 38 is switched off, for example in the case of "hang fire", the cartridges no longer reach the weapon 12, 13, but are transported back again by the endless chain 24a, 25a. This first endless chain 24a, 25a is guided over two deflection rollers 39 and passes through the flexible channel 24, 25. The second endless chain 16b, 19b leads from the first ammunition container 16, 19 to the first endless chain 24a, 25a. The third endless chain 18b, 21b leads from the second ammunition container 18, 21 to the first endless chain 24a, 25a. The first endless chain 24a, 25a and the second endless chain 16b, 19b can be coupled to one another via the one clutch 35. The first endless chain 24a, 25a and the third endless chain 18b, 21b can be coupled to one another via the other clutch 36.

Solange die Weiche 28 eingeschaltet ist, gelangen die Patronen 32 von der zweiten Endloskette 16b,19b auf die erste Endloskette 24a,25a. Wird die Weiche 28 umgeschaltet, so bleiben die Patronen 32 auf der zweiten Endloskette 16b,19b und werden zurück gegen den ersten Munitionsbehälter 16,19 gefördert. Das gleiche gilt für die Weiche 29. Solange die Weiche 29 eingeschaltet ist, gelangen die Patronen 32 von der dritten Endloskette 18b,21b auf die erste Endloskette 24a,25a. Wird die Weiche 29 umgeschaltet, so bleiben die Patronen 32 auf der dritten Endloskette 18b,21b und werden zurück gegen den zweiten Munitionsbehälter 18,21 gefördert. In jedem der vier Munitionsbehälter 16,18,19,21 befindet sich je eine Endloskette 16c,18c,19c,21c, welche mit je einem Motor 40 bzw. 41 verbunden ist zum Antrieb dieser vier Endlosketten 16c,18c,19c,21c.As long as the switch 28 is switched on, the cartridges 32 pass from the second endless chain 16b, 19b to the first endless chain 24a, 25a. If the switch 28 is switched over, the cartridges 32 remain on the second endless chain 16b, 19b and are conveyed back against the first ammunition container 16, 19. The same applies to the switch 29. As long as the switch 29 is switched on, the cartridges 32 pass from the third endless chain 18b, 21b to the first endless chain 24a, 25a. If the switch 29 is switched over, the cartridges 32 remain on the third endless chain 18b, 21b and are conveyed back against the second ammunition container 18, 21. In each of the four ammunition containers 16, 18, 19, 21 there is an endless chain 16c, 18c, 19c, 21c, which is connected to a motor 40 or 41 for driving these four endless chains 16c, 18c, 19c, 21c.

Die Wirkungsweise der beschriebenen Vorrichtung zum Zuführen von Patronen aus einem ortsfesten Magazin zu einer Feuerwaffe ist wie folgt:The operation of the described device for feeding cartridges from a stationary magazine to a firearm is as follows:

Zum Auslösen eines Seriefeuers wird der hier nicht dargestellte Abzug der Feuerwaffen 12 oder 13 betätigt. Gemäss Fig.8 werden dabei die Motoren 37,40 und 41 der Feuerwaffen 12,13 und der Munitionsmagazine 16,19 bzw. 18,21 eingeschaltet, je nachdem, welche Munitionsart gewünscht wird. Gleichzeitig wird je nach Munitionsart die eine oder die andere der Kupplungen 35 und 36 eingeschaltet und gemäss Fig.6 müssen die drei Weichen 28,29 und 42 gestellt werden. Während das Waffenrohrbündel 15 auf die volle Tourenzahl beschleunigt wird, beginnt auch die Zufuhr von Munition, wobei sich die erste Patrone, die der Waffe 12,13 zugeführt werden soll, zu Beginn des Vorgangs beim Sensor 50 oder 51 befindet, je nach der gewünschten Munitionsart, siehe Fig.6. Diese Patronen 32 gelangen zu den Übergaberädern 26a und 26b oder zu den Übergaberädern 27a und 27b und von dort zu den Endlosketten 24a und 25a, und sobald das Waffenrohrbündel 15 die volle Tourenzahl erreicht hat, gelangt auch die erste Patrone 32 zur Feuerwaffe 12 oder 13. Nach beispielsweise 0,5 Sekunden wird gemäss Fig.7 der erste Schuss abgefeuert.To trigger a series fire, the trigger of the firearms 12 or 13, not shown here, is actuated. According to FIG. 8, the motors 37, 40 and 41 of the firearms 12, 13 and the ammunition magazines 16, 19 and 18, 21 are switched on, depending on which type of ammunition is desired. At the same time, depending on the type of ammunition, one or the other of the clutches 35 and 36 is switched on and, according to FIG. 6, the three switches 28, 29 and 42 must be set. While the weapon barrel bundle 15 is being accelerated to the full number of revolutions, the supply of ammunition also begins, the first cartridge to be supplied to the weapon 12, 13 being at the sensor 50 or 51 at the beginning of the process, depending on the desired type of ammunition , see Fig. 6. These cartridges 32 go to the transfer wheels 26a and 26b or to the transfer wheels 27a and 27b and from there to the endless chains 24a and 25a, and as soon as the weapon barrel bundle 15 has reached the full number of revolutions, the first one also arrives Cartridge 32 for firearm 12 or 13. After 0.5 seconds, for example, the first shot is fired according to FIG.

Sobald das Seriefeuer beendet werden soll, wird je nach Munitionsart gemäss Fig.6 eine der Weichen 28 oder 29 und kurz danach eine der Kupplungen 35 oder 36 betätigt, d.h. die Weiche 28 bzw. 29 wird so gestellt, dass keine Patronen zugeführt werden und die Kupplung 35 oder 36 wird ausgeschaltet, wenn das Übergaberad 26a oder 27a keine Patronen mehr führt. Bis die Feuerwaffe 12,13 zum Stillstand kommt, d.h. bis sich das Rohrbündel 15 nicht mehr dreht, werden alle auf der Endloskette 24a befindlichen Patronen 32 verschossen. Gleichzeitig wird die Endloskette 16b, 19b bzw. 18b, 21b bis zum Stillstand abgebremst und anschliessend rückwärts bewegt, bis die erste Patrone 32 sich wieder in der Ausgangslage beim Sensor 50 bzw. 51 befindet. Aus Fig.7 ist ersichtlich, dass 0,5 Sekunden nach Ausschalten des Motors 40 bzw. 41 die Munitionszufuhr zum Stillstand kommt und dass 0,25 Sekunden nach Ausschalten des Motors 37 das Waffenrohrbündel 15 zum Stillstand kommt. Die Patronenzufuhr gelangt erst nach 1,0 Sekunden in die Startposition beim Sensor 50 bzw. 51 zurück. Der zweite Munitionsbehälter 18,21 ist bereits nach 0,4 Sek.für den nächsten Feuerstoss bereit.As soon as the series fire is to be ended, depending on the type of ammunition according to FIG. 6, one of the switches 28 or 29 and shortly afterwards one of the couplings 35 or 36 is actuated, i.e. the switch 28 or 29 is set so that no cartridges are supplied and the clutch 35 or 36 is switched off when the transfer wheel 26a or 27a no longer carries cartridges. Until the firearm 12, 13 comes to a standstill, i.e. until the tube bundle 15 no longer rotates, all the cartridges 32 located on the endless chain 24a are fired. At the same time, the endless chain 16b, 19b or 18b, 21b is braked to a standstill and then moved backwards until the first cartridge 32 is again in the starting position at the sensor 50 or 51. It can be seen from FIG. 7 that the ammunition supply comes to a standstill 0.5 seconds after the motor 40 or 41 is switched off and that the weapon barrel bundle 15 comes to a standstill 0.25 seconds after the motor 37 is switched off. The cartridge feed only returns to the starting position at sensor 50 or 51 after 1.0 seconds. The second ammunition container 18, 21 is ready for the next round of fire after only 0.4 seconds.
