Abstract

In a fire limiter for automatic firearms with hammer blow detonation, a pawl (38) is supported pivotally directly on a bearing on the hammer arranged eccentrically to the latter's pivoting axis (1). The pawl transfers essentially the entire striking motion of the hammer to a wheel ratchet, which at every shot rotates by one tooth and is held in any given position by a spring-loaded stop pawl. The wheel ratchet is provided with a cam which, after a predetermined number of intermittent stops, activates a fire disconnector which preferably comprises a trip-releasing catch (26), supported pivotally on the trigger (16), and a sear (12), supported pivotally on the same shaft (14) as the trigger (16). The catch (26) initially latches the sear (12) and is pulled away from the sear (12) by the wheel ratchet, whereby the sear is released to drop into a detent (11) on the hammer (2).

Description

Die Erfindung betrifft einen Schußzahlbegrenzer für automatische Feuerwaffen mit Hahnschlagzündung, insbesondere Handfeuerwaffen, mit einem Klinkenrad, das bei jedem Schuß von einer mit dem Hahn in fester getrieblicher Verbindung stehenden Schaltklinke um einen Zahn verdreht und in seiner jeweiligen Stellung an einem federbelasteten Sperrglied gehalten wird und das mit einer Steuerkurbel versehen ist, die nach einer vorbestimmen Anzahl von Schaltschritten ein die Schußfolge unterbrechendes Glied betätigt.The invention relates to a number of shot limiters for automatic firearms with tap firing, in particular handguns, with a ratchet wheel, which is rotated by a tooth in each shot by a pawl in fixed gear connection with the tap and held in its respective position on a spring-loaded locking member and that is provided with a control crank which, after a predetermined number of switching steps, actuates a member which interrupts the firing sequence.

Ein solcher Schußzahlbegrenzer ist aus der FR-A-2 201 451 bekannt. Die Schaltklinke ist hier unmittelbar am Hahn angelenkt und nimmt in der vorderen Stellung des Hahnes, von der aus die Fortschaltung des Klinkenrades bewirkt wird, eine Stellung ein, in der sich ihr Zahn im Abstand von den Zähnen des Klinkenrades befindet. Das Fortschalten des Klinkenrades erfolgt erst auf dem letzten Teil der vom Verschluß der Feuerwaffe bewirkten Spannbewegung des Hahnes. Hierbei treten schlagartige Beanspruchungen auf, die den Schußzähler und die damit zusammenwirkenden Teile sehr hoch beanspruchen. Auch kann es dabei leicht zu Prellvorgängen kommen, die die Betriebssicherheit des Schußzählers beeinträchtigen.Such a shot number limiter is known from FR-A-2 201 451. The pawl is articulated here directly to the tap and, in the front position of the tap, from which the ratchet wheel is advanced, assumes a position in which its tooth is at a distance from the teeth of the ratchet wheel. The ratchet wheel is only advanced on the last part of the cock's cocking movement caused by the firearm's breech. Sudden stresses occur here, which stress the shot counter and the parts interacting therewith very high. Bouncing processes can also easily occur, which impair the operational reliability of the shot counter.

Weitere bekannte Schußzahlbegrenzer, wie sie in der DE-B-2 136 101 und der DE-B-1 297 002 beschrieben sind, weisen die gleichen Mängel auf. Bei dem aus der DE-B-2 136 101 bekannten Schußzahlbegrenzer erfolgt die Betätigung der Schaltklinke mittels einer mit dem Hahn gelenkig verbundenen Stange, die jeweils gegen Ende der Spannbewegung des Hahnes gegen einen Arm einer Schaltklinke stößt und dadurch die Schaltklinke verschwenkt, die bei ihrer Schwenkbewegung das Klinkenrad mitnimmt. Bei dem aus der DE-B-1 297 002 bekannten Schußzahlbegrenzer ist anstelle eines Klinkenrades eine geradlinig varschiebbare Zahnstange vorgesehen, die von einer Schaltklinke verschoben wird. Hier kommt der Hahn selbst gegen Ende seiner Spannbewegung mit der Schaltklinke in Eingriff und überträgt seine Bewegung auf die Schaltklinke, die ihrerseits die Zahnstange mitnimmt.Other known shot limiters, as described in DE-B-2 136 101 and DE-B-1 297 002, have the same shortcomings. In the shot number limiter known from DE-B-2 136 101, the pawl is actuated by means of a rod articulated to the tap, which in each case abuts against an arm of a pawl towards the end of the cocking movement and thereby pivots the pawl which moves at it Swiveling movement takes the ratchet wheel with it. In the shot number limiter known from DE-B-1 297 002, instead of a ratchet wheel, a rectilinearly variable rack is provided which is shifted by a ratchet. Here the valve itself comes into engagement with the pawl at the end of its tensioning movement and transmits its movement to the pawl, which in turn takes the rack with it.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Schußzahlbegrenzer der eingangs genannten Art so auszubilden, daß seine Beanspruchung vermindert und seine Betriebssicherheit erhöht wird.The invention is therefore based on the object of designing a shot limiter of the type mentioned in such a way that its stress is reduced and its operational safety is increased.

Diese Aufgabe wird nach der Erfindung dadurch gelöst, daß der Hub der Schaltklinke und die Zahnung des Klinkenrades derart aufeinander abgestimmt sind, daß im wesentlichen die gesamte, in einer Richtung verlaufende Bewegung des Hahnes auf das Klinkenrad übertragen wird.This object is achieved according to the invention in that the stroke of the switching pawl and the toothing of the ratchet wheel are coordinated with one another in such a way that essentially the entire one-way movement of the tap is transmitted to the ratchet wheel.

Die Ausnutzung der gesamten, in einer Richtung verlaufenden Hahnbewegung führt zu einer bedeutenden Erhöhung der Bewegungsdauer und damit einer bedeutenden Verminderung der Schaltgeschwindigkeit, wodurch eine übermäßige Beschleunigung und die Anwendung übermäßiger Kräfte vermieden wird, wie sie sonst zum Erreichen der hohen Beschleunigungen aufgebracht werden müssen. Da die Bewegungen nicht mehr so schlagartig zu erfolgen brauchen wie bisher, steht auch mehr Zeit zum Einfallen der federbelasteten Sperrklinke zur Verfügung, so daß auch die Federbelastung dieser Klinke vermindert und deren Einfallszeit vergrößert werden kann, wodurch die Gefahr von Fehlern im Bewegungsablauf und in der Schußzählung vermindert wird.Utilizing all of the unidirectional tap movement results in a significant increase in the duration of movement and thus a significant reduction in switching speed, thereby avoiding excessive acceleration and the application of excessive forces that would otherwise have to be applied to achieve the high accelerations. Since the movements no longer need to take place as suddenly as before, there is also more time available for the spring-loaded pawl to engage, so that the spring load on this pawl can also be reduced and its incidence increased, thereby increasing the risk of errors in the movement sequence and in the Shot count is decreased.

Bei einer bevorzugten Ausführungsform der Erfindung nimmt die Schaltklinke das Klinkenrad bei der Schlagbewegung des Hahnes mit. Die Schlagbewegung des Hahnes erfolgt unter dem Einfluß der den Hahnbelastenden Schlagfeder und ist daher ausschließlich durch die Konstruktion der Waffe bedingt, anders als der unter dem Einfluß des Verschlußrücklaufes stattfindende Spannvorgang, der in hohem Maße von der Art der verschossenen Munition abhängt.In a preferred embodiment of the invention, the pawl takes the ratchet wheel with the stroke movement of the tap. The striking movement of the cock takes place under the influence of the striking spring loading the cock and is therefore solely due to the design of the weapon, unlike the tensioning process taking place under the influence of the breech return, which depends to a large extent on the type of ammunition fired.

Daher ist bei der Ausnutzung der Schlagbewegung des Hahnes eine genaue konstruktive Abstimmung des Schaltvorganges des Schußzahlbegrenzers auf den Ablauf der Hahnbewegung möglich, die zu einer optimalen Funktion des Schußzahlbegrenzers führt. Außerdem ist die Ausnutzung der Schlagbewegung des Hahnes auch für die Unterbrechung der Schußfolge günstig, weil nach dem Fortschalten des Schußzahlbegrenzers die gesamte Rücklaufzeit des Verschlusses zur Verfügung steht, um die von dem Klinkenrad gesteuerten Glieder zur Unterbrechung der Schußfolge zum Fangen des gespannten Hahnes vorzubereiten.Therefore, when using the percussion movement of the tap, an exact constructive adjustment of the switching process of the shot number limiter to the sequence of the tap movement is possible, which leads to an optimal function of the shot number limiter. In addition, the use of the flapping movement of the cock is also favorable for the interruption of the shot sequence, because after the shot number limiter has been advanced, the entire return time of the breech is available in order to prepare the limbs controlled by the ratchet wheel to interrupt the shot sequence for catching the cocked cock.

Die Ausnützung der gesamten, in einer Richtung verlaufenden Bewegung des Hahnes zum Fortschalten des Klinkenrades kann in einfacher Weise dadurch erfolgen, daß die Schaltklinke unmittelbar auf einem am Hahn zu dessen Schwenkachse exzentrisch angeordneten Lager schwenkbar gelagert ist. Durch die Anordnung dieses Lagers kann die Größe und der zeitliche Ablauf der von der Schaltklinke ausgeführten Schaltbewegung auf die Hahnbewegung optimal abgestimmt werden. Außerdem werden auf diese Weise zusätzliche Zwischenglieder vermieden, welche die Bewegungsabläufe komplizieren und die zu bewegenden Massen erhöhen. Das exzentrische Lager kann einen relativ großen Durchmesser haben, so daß die beim Schaltvorgang auftretenden Kräfte großflächig aufgenommen werden können.The entire, unidirectional movement of the tap for advancing the ratchet wheel can be utilized in a simple manner in that the pawl is pivotally mounted directly on a bearing which is arranged eccentrically on the tap to its pivot axis. The size and timing of the switching movement carried out by the switching pawl can be optimally coordinated with the tap movement by the arrangement of this bearing. In addition, additional intermediate elements are avoided in this way, which complicate the movement sequences and increase the masses to be moved. The eccentric bearing can have a relatively large diameter, so that the forces occurring during the switching process can be absorbed over a large area.

Eine besonders einfache und platzsparende Ausbildung eines solchen Schußzahlbegrenzers läßt sich dadurch erzielen, daß die Schaltklinke und das Klinkenrad von einer gemeinsamen Schraubendruckfeder belastet werden, die zwischen zwei an der Schaltklinke bzw. dem Klinkenrad angebrachten, annähernd zueinander parallelen Armen angeordnet und bestrebt ist, die Schaltklinke mit dem Klinkenrad in Eingriff zu halten und zugleich das Klinkenrad in seine Ruhestellung zurückzubringen. Dabei kann die Schraubendruckfeder auf einer an dem Arm des Klinkenrades angelenkten und eine Aussparung in dem Arm der Schaltklinke durchsetzenden Federstange angeordnet sein.A particularly simple and space-saving design of such a shot number limiter can be achieved in that the switching pawl and the ratchet wheel are loaded by a common helical compression spring which is arranged and strived between two arms which are attached to the switching pawl and the ratchet wheel and are approximately parallel to one another and which To hold the pawl in engagement with the ratchet wheel and at the same time to return the ratchet wheel to its rest position. The helical compression spring can be arranged on a spring rod articulated on the arm of the ratchet wheel and penetrating a recess in the arm of the ratchet.

Die oben erwähnte, relativ geringe Geschwindigkeit der Bewegungsvorgänge erlaubt es auch, die Schußunterbrechung in einer zugleich besonders einfachen und besondere zuverlässigen Weise zu bewirken, ohne daß erhebliche Eingriffe in ein bekanntes Abzugssystem erfolgen müssen, das auf Einzel-und Dauerfeuer umstellbar ist und einen mit dem Hahn zusammenwirkenden Abzugshebel aufweist, der auf der gleichen Achse wie der Abzug schwenkbar gelagert ist. Auch die oben erwähnten, bekannten Schußzahlbegrenzer wirken mit einem solchen Abzugssystem zusammen, erfordern jedoch größere Eingriffe und insbesondere die Anbringung zusätzlicher Fangklinken. Bei einer bevorzugten Ausführungsform des erfindungsgemäßen Schußzahlbegrenzers kommt das Klinkenrad zur Unterbrechung der Schußfolge lediglich mit einer im Abzug schwenkbar gelagerten Auslöseklinke in Eingriff, die den auf der gleichen Achse wie der Abzug schwenkbar gelagerten Abzugshebel abstützt, und zieht diese Auslöseklinke von dem Abzugshebel ab, so daß der Abzugshebel zum Einfallen in die dafür vorgesehene Hahnrast freigegeben wird. Es braucht demnach kein zusätzliches Glied vorgesehen zu werden, das den Hahn nach der Unterbrechung der Schußfolge festhält und mittels der Abzugseinrichtung ausgelöst werden muß, sondern es wird der ohnehin vorhandene Abzugshebel auch zum Unterbrechen der Schußfolge verwendet. Die Auslöseklinke tritt dabei an die Stelle eines bisher im Abzug vorgesehenen, ortsfesten Anschlages für den Abzugshebel.The above-mentioned, relatively slow speed of the movement processes also allows the interruption of the shot to be effected in a particularly simple and particularly reliable manner at the same time, without significant interventions in a known trigger system which can be converted to single and continuous fire and one with which Hahn cooperating trigger lever which is pivotally mounted on the same axis as the trigger. The known shot limiters mentioned above also interact with such a trigger system, but require major interventions and in particular the attachment of additional catches. In a preferred embodiment of the number of shot limiters according to the invention, the ratchet wheel interrupts the firing sequence only with a trigger pawl pivotally mounted in the trigger, which supports the trigger lever pivotally mounted on the same axis as the trigger, and pulls this trigger pawl from the trigger lever, so that the trigger is released to drop into the tap stop provided for this purpose. Accordingly, there is no need to provide an additional link which holds the tap after the interruption of the firing sequence and must be triggered by the trigger device, but the trigger lever which is present anyway is also used to interrupt the firing sequence. The release pawl replaces a fixed stop for the trigger that was previously provided in the trigger.

When the trigger is not actuated, the tap 2 is then held in the clamping position by a trigger lever 12, which also engages with its arm 15 in a catch 11 on the tap 2, as can also be seen in FIG. 1.

Der Abzugshebel 12 ist im Abzugskasten 4 auf der gleichen Welle 14 gelagert wie der Abzug 16. Der Abzugehebel 12 weist zur Lagerung auf der Welle 14 ein Langloch auf und stützt sich mit der dem Hahn 2 zugewandten Langlochhälfte 13 an der Lagerwelle 14 ab, wenn der Abzugshebel 12 mit dem Hahn 2 in Eingriff steht. In dem Abzugshebet 12 ist ein unter Federdruck stehender Bolzen 17 angbordnet, der bestrebt ist, den Abzugshebel 12 in seiner Längsrichtung gegenüber der Welle 14 derart zu verschieben, daß der Abzugshebel 12 mit seiner dem Hahn 2 abgewandten Langlochhälfte 18 an der Welle 14 zur Anlage kommt. Weiterhin wird der Abzugshebel 12 an seinem dem Hahn 2 zugewandten Arm 15 von einer federbelasteten Laufrolle 33 in Richtung auf den Hahn 2 gedrückt und bei unbetätigtem Abzug mit der Rast 11 des Hahnes 2 in Eingriff gehalten.The trigger lever 12 is mounted in the trigger box 4 on the same shaft 14 as the trigger 16. The trigger lever 12 has an elongated hole for mounting on the shaft 14 and is supported on the bearing shaft 14 with the elongated hole half 13 facing the tap 2 when the Trigger lever 12 is engaged with the tap 2. Arranged in the trigger lever 12 is a bolt 17 under spring pressure, which strives to move the trigger lever 12 in its longitudinal direction relative to the shaft 14 in such a way that the trigger lever 12 comes into contact with the shaft 14 with its slot half 18 facing away from the tap 2 . Furthermore, the trigger lever 12 on its arm 15 facing the tap 2 is pressed by a spring-loaded roller 33 in the direction of the tap 2 and is held in engagement with the catch 11 of the tap 2 when the trigger is not actuated.

Der auf der Welle 14 gelagerte Abzug 16 ist durch eine nicht dargestellte Feder im Uhrzeigersinne belastet, so daß der Abzug 16 in seiner Ruhestellung mit einem Arm 19 an einem Anschlagbolzen 20 anliegt. Der Abzug 16 weist eine Nase 21 auf, die mit einer Kuvenfläche 22 an der im Abzugskasten 4 drehbar gelagerten Sicherungswelle 23 zusammenwirkt. Weiterhin ist in dem von einem Hohlprofil gebildeten Abzug 16 auf einem Bolzen 25 eine Auslöseklinke 26 drehbar gelagert, die von einer Feder 27 entgegen dem Uhrzeigersinne belastet ist. In ihrer Ruhestellung stützt sich die Auslöseklinke 26 mit einem Arm 28 an einem im Abzug 16 angebrachten Anschlag 31 ab.The trigger 16 mounted on the shaft 14 is loaded clockwise by a spring, not shown, so that the trigger 16 in its rest position rests with an arm 19 on a stop pin 20. The trigger 16 has a nose 21 which cooperates with a cam surface 22 on the safety shaft 23 which is rotatably mounted in the trigger box 4. Furthermore, in the trigger 16 formed by a hollow profile, a release pawl 26 is rotatably mounted on a bolt 25 and is loaded counterclockwise by a spring 27. In its rest position, the release pawl 26 is supported with an arm 28 on a stop 31 attached in the trigger 16.

In der in Fig. 1 dargestellten Lage der Sicherungswelle 23 ist die Waffe gesichert. Der Arm 21 des Abzuges 16 liegt an der Außenseite der Kurvenfläche 22 an und kann daher nicht aus der dargestellten Lage ausgelenkt werden. Daher kann auch nicht der Abzugshebel 12 aus der Rast 11 am Hahn 2 ausgelenkt werden, so daß der Hahn in der in Fig. 1 wiedergegebene Stellung sicher gehalten ist. Durch Drehen der Sicherungswelle im Uhrzeigersinn kann die Kurvenfläche 22 mehr oder weniger weit aus dem Bereich des Armes 21 des Abzuges 16 ausgelenkt werden, um dadurch die Abzugseinrichtung auf Einzel- oder Dauerfeuer einzustellen. Zwischen den Einstellungen für Einzel- und Dauerfeuer befindet sich die Stellung "Dreischuß", die in den Fig. 2 bis 4 wiedergegeben ist und bei der der Abzug 16 soweit ausgelenkt werden kann, daß er mit seinem Arm 19 an einem im Abzugskasten 4 angebrachten Anschlag 36 zur Anlage kommt.In the position of the safety shaft 23 shown in FIG. 1, the weapon is secured. The arm 21 of the trigger 16 bears against the outside of the curved surface 22 and can therefore not be deflected from the position shown. Therefore, the trigger 12 can not be deflected from the catch 11 on the tap 2, so that the tap is held securely in the position shown in Fig. 1. By turning the locking shaft clockwise, the curved surface 22 can be more or less far from the area of the arm 21 the trigger 16 are deflected, thereby setting the trigger device to single or continuous fire. Between the settings for single and continuous fire is the "three shot" position, which is shown in FIGS. 2 to 4 and in which the trigger 16 can be deflected so far that it has its arm 19 on a stop attached in the trigger box 4 36 comes to the plant.

Wird der Abzug 16 bei entsicherter Waffe betätigt, so wird der Abzugshebel 12 beim Verschwenken des Abzuges 16 von der Auslöseklinke 26 mitgenommen, die mit ihrer Nase 29 am Arm 34 des Abzugshebels 12 zur Anlage kommt. Sobald der Arm 15 des Abzugshebels 12 von der Rast 11 des Hahnes 2 frei ist, verschiebt der unter Federdruck stehende Bolzen 17 den Abzugshebel 12 gegenüber der Welle 14 und damit gegenüber dem Abzug 16 mit der Auslöseklinke 26, so daß der Hebelarm 34 von der Nase 29 der Auslöseklinke 26 abrutscht und an der Schulter 30 der Auslöseklinke zur Anlage kommt. Dabei führt der Abzugehebel 12 eine Schwenkung im Uhrzeigersinne aus, die seinen Arm 15 mit der Rast 11 des Hahnes 2 wieder in Eingriff bringt, wenn der Schwenkwinkel des Abzuges 16 bei Einstellung auf Einzelfeuer durch die Kurvenfläche 22 in nicht näher dargestellter Weise begrenzt wird.If the trigger 16 is actuated with the weapon unlocked, the trigger lever 12 is taken along by the trigger pawl 26 when the trigger 16 is pivoted, which comes into abutment with its nose 29 on the arm 34 of the trigger lever 12. As soon as the arm 15 of the trigger lever 12 is free from the catch 11 of the tap 2, the spring-loaded bolt 17 moves the trigger lever 12 relative to the shaft 14 and thus relative to the trigger 16 with the release pawl 26, so that the lever arm 34 is removed from the nose 29 of the release pawl 26 slips and comes to rest on the shoulder 30 of the release pawl. The trigger lever 12 executes a clockwise pivoting, which brings its arm 15 back into engagement with the catch 11 of the tap 2 when the pivoting angle of the trigger 16 is limited by the cam surface 22 in a manner not shown when set to single fire.

Bei der in den Fig. 2 bis 4 dargestellten Einstellung auf "Dreischuß" ist jedoch der Abzug 16 soweit verschwenkt, daß derAbzugshebei 12 auch dann außer Eingriff mit dem Hahn 2 gehalten wird, wenn der Abzugshebel 12 mit seinem Arm 34 von der Nase 29 abgerutscht ist und an der Schulter 30 anliegt. Es kommt nun der in den Fig. 2 bis 4 dargestellte Schußzahlbegrenzer zur Wirkung, der ein in dem Abzugskasten 4 mittels einer Hohlnabe 48 konzentrisch zur Sicherungswelle 23 drehbar gelagertes Klinkenrad 39 umfaßt. Mit diesem Klinkenrad 39 wirkt eine Schaltklinke 38 zusammen, die auf einem am Hahn 2 exzentrisch zur Welle 1 angebrachten Lager 37 angeordnet ist. Die Exzentrizität des Lagers 37 ist so bemessen, daß bei jeder Zündbewegung des Hahnes 2 über einen an der Schaltklinke 38 angebrachten Schaltzahn 40 das Klinkenrad 39 jeweils um einen seiner Zähne 41 verschwenkt wird. Die Schaltklinke 38 ist mit einem seitlich abstehenden Arm 42 versehen, der sich im wesentlichen zu einem Arm 45 des Klinkenrades 39 parallel erstreckt. Zwischen diesen beiden Armen 42 und 45 ist auf einer Federstange 43 eine Druckfeder 44 angeordnet. Die Federstange 43 ist an einem Ende am Arm 45 des Klinkenrades 39 schwenkbar eingehängt und mit ihrem anderen Ende dem Arm 42 der Schaltklinke 38 verschiebbar gelagert. Die Druckfeder 44 übt auf die Arme der Schaltklinke 38 bzw. des Klinkenrades 39 solche Drehmomente aus, daß einerseits die Schaltklinke 38 bestrebt ist, mit ihrem Schaltzahn 40 zwischen die Zähne 41 des Klinkenrades einzugreifen, während andererseits das Klinkenrad 39 bestrebt ist, eine Drehung im Uhrzeigersinne auszuführen. Mit den Zähnen 41 wirkt weiterhin als Sperrglied eine Sperrklinke 46 zusammen, die ebenfalls im Abzugskasten 4 auf einer Welle 61 schwenkbar gelagert und von einer Feder 62 belastet ist, die bestrebt ist, den Zahn 47 der Sperrklinke 46 mit den Zähnen 41 des Klinkenrades 39 in Eingriff zu halten.2 to 4, the trigger 16 is pivoted to such an extent that the trigger lever 12 is kept out of engagement with the tap 2 even when the trigger lever 12 slips off the nose 29 with its arm 34 is and rests on the shoulder 30. The shot number limiter shown in FIGS. 2 to 4 now comes into effect, which comprises a ratchet wheel 39 rotatably mounted in the trigger box 4 by means of a hollow hub 48 concentrically with the securing shaft 23. This ratchet wheel 39 interacts with a ratchet pawl 38 which is arranged on a bearing 37 attached to the cock 2 eccentrically to the shaft 1. The eccentricity of the bearing 37 is dimensioned such that the pawl wheel 39 is pivoted about one of its teeth 41 with each ignition movement of the tap 2 via a switching tooth 40 attached to the switching pawl 38. The pawl 38 is provided with a laterally projecting arm 42 which extends essentially parallel to an arm 45 of the ratchet wheel 39. A compression spring 44 is arranged on a spring rod 43 between these two arms 42 and 45. The spring rod 43 is pivotally suspended at one end on the arm 45 of the ratchet wheel 39 and is displaceably mounted on the arm 42 of the switching pawl 38 at its other end. The compression spring 44 exerts such torques on the arms of the pawl 38 or the ratchet wheel 39 that on the one hand the pawl 38 strives to engage with its switching tooth 40 between the teeth 41 of the ratchet wheel, while on the other hand the ratchet wheel 39 strives to rotate in Execute clockwise. With the teeth 41, a pawl 46 also acts together as a locking member, which is also pivotally mounted in the trigger box 4 on a shaft 61 and is loaded by a spring 62, which strives to tooth 47 of the pawl 46 with the teeth 41 of the ratchet wheel 39 in Keep engaging.

Wie bereits erwähnt, wird bei der Dreischuß-Einstellung bei jeder Zündbewegung des Hahnes von der in Fig. 1 dargestellten Spannstellung in die in den Fig. 2 und 3 wiedergegebene Schlagstellung, die unter der Wirkung der Schraubendruckfeder 3 erfolgt, das Klinkenrad 39 jeweils um einen Zahn fortgeschaltet. Die Fortschaltungsbewegung erfolgt über die gesamte Schlagbewegung des Hahnes und erfolgt nur unter dem genau definierten Einfluß der den Hahn belastenden Schraubendruckfeder. Das Fortschalten des Klinkenrades erfolgt daher relativ langsam und gleichmäßig, so daß ein einwandfreies Fortschalten des Klinkenrades bei jedem Schuß gewährleistet ist.As already mentioned, in the three-shot setting with each ignition movement of the tap from the tensioning position shown in FIG. 1 to the stroke position shown in FIGS. 2 and 3, which takes place under the action of the helical compression spring 3, the ratchet wheel 39 by one Tooth advanced. The indexing movement takes place over the entire stroke movement of the valve and takes place only under the precisely defined influence of the helical compression spring loading the valve. The ratchet wheel is therefore advanced relatively slowly and evenly, so that a correct advancement of the ratchet wheel is guaranteed with every shot.

Nach einer durch die Anzahl der Zähne 41 vorgegebenen Anzahl von Schüssen, bei dem dargestellten Ausführungsbeispiel nach drei Schüssen, kommt eine Steuerkurve 49, die von einer an der Hohlnabe 48 des Klinkenrades 39 angebrachte Nase gebildet wird, mit einem seitlichen Anschlag 70 an der Auslöseklinke 26 in Eingriff und verschwenkt, wie aus Fig. 4 ersichtlich, die Auslöseklinke 26 so weit, daß sie mit ihrer Schulter 30 unter dem Arm 34 des Abzugshebels 12 herausgezogen wird und dadurch der Abzugshebel 12 unter der Wirkung der gefederten Rolle 33 wieder im Uhrzeigersinne soweit verschwenkt wird, daß sein Arm 15 mit der Nase 11 des Hahnes 2 in Eingriff kommt, wenn nach Auslösen des Schusses der Hahn 2 vom rücklaufenden Verschluß gespannt wird. Da zwischen der Freigabe des Abzugshebels 12 und dem Fangen des Hahnes 2 die gesamte Zeit der Schußauslösung und des Verschluß-Rücklaufes liegt, ist gewährleistet, daß der Abzugshebel 12 die Fangstellung rechtzeitig erreicht und mit dem Hahn 2 mit Sicherheit in Eingriff kommt, um ihn nach Ablauf der gewünschten Schußfolge zu arretieren. Es wird also die Schußfolge durch Verschwenken der Auslöseklinke 26 unterbrochen, die also das von dem Klinkenrad 39 betätigte, die Schußfolge unterbrechende Glied bildet.After a number of shots predetermined by the number of teeth 41, in the illustrated embodiment after three shots, a control cam 49, which is formed by a nose attached to the hollow hub 48 of the ratchet wheel 39, comes with a lateral stop 70 on the release pawl 26 engaged and pivoted, as shown in Fig. 4, the release pawl 26 so far that it is pulled out with its shoulder 30 under the arm 34 of the trigger lever 12 and thereby the trigger lever 12 pivoted again clockwise under the action of the sprung roller 33 is that his arm 15 comes into engagement with the nose 11 of the cock 2 when the cock 2 is tensioned by the return closure after triggering the shot. Since between the release of the trigger lever 12 and the catching of the cock 2 is the entire time of the triggering of the shot and the breech return, it is ensured that the trigger lever 12 reaches the catch position in good time and comes into engagement with the cock 2 with certainty to him after Lock the sequence of the desired sequence of shots. The sequence of shots is thus interrupted by pivoting the release pawl 26, which thus forms the link which is actuated by the ratchet wheel 39 and interrupts the sequence of shots.

Bei Loslassen des Abzuges kommt die in Bild 3 ersichtliche, aus dem Abzug 16 seitlich herausstehende Verlängerung des Lagerbolzens 25 für die Auslöseklinke 26 mit den Armen 50 und 51 der Schaltklinke 38 bzw. der Sperrklinke 46 in Eingriff und hebt diese beiden Klinken von dem Klinkenrad ab, so daß das Klinkenrad unter der Wirkung der Druckfeder 44 in seine Ausgangslage zurückkehren kann, in der es mit seinem Arm 45 an einem Anschlag 52 anliegt.When the trigger is released, the extension of the bearing pin 25 for the release pawl 26, which can be seen laterally from the trigger 16, comes into engagement with the arms 50 and 51 of the pawl 38 and the pawl 46 and lifts these two pawls from the ratchet wheel , so that the ratchet wheel can return to its starting position under the action of the compression spring 44, in which it rests with its arm 45 against a stop 52.

Beim erneuten Durchziehen des Abzuges wird die durch den Schußzahlbegrenzer bestimmte Schußfolge wiederholt.When the trigger is pulled again, the sequence of shots determined by the shot number limiter is repeated.

Wie insbesondere aus den Fig. 2 und 3 ersichtlich, greift die Schaltklinke 38 mit ihrem Rand 63 in eine hierfür vorgesehene Aussparung in der Sicherungswelle 23 ein. Bei Einstellung auf Dauerfeuer ist die Sicherungswelle so weit verdreht, daß die Schaltklinke 38 mit ihrem Rand 63 am Umfang der Sicherungswelle anliegt und dadurch mit dem Klinkenrad 39 außer Eingriff gehalten wird. Daher wird bei Dauerfeuer der Schußzahlbegrenzer nicht wirksam, und es wird die Schußfolge erst durch Freigeben des Abzuges 18 unterbrochen.As can be seen in particular from FIGS. 2 and 3, the pawl 38 engages with its Edge 63 into a recess provided for this purpose in the securing shaft 23. When set to continuous fire, the safety shaft is rotated so far that the pawl 38 rests with its edge 63 on the circumference of the safety shaft and is thereby kept out of engagement with the ratchet wheel 39. Therefore, the shot number limiter is not effective in continuous fire, and the sequence of shots is only interrupted by releasing the trigger 18.

Es versteht sich, daß die Erfindung nicht auf das dargestellte Ausführungsbeispiel beschränkt ist, sondern Abweichungen davon möglich sind, ohne den Rahmen der Erfindung zu verlassen. So kann beispielsweise anstelle des Exzenters zum Antrieb der Schaltklinke eine Art Kurbeltrieb verwendet werden, und es können die Schaltklinke und das Schaltrad mittels voneinander unabhängiger Federn belastet sein. Auch könnte das Fortschalten deß Klinkenrades von der Spannbewegung des Hahnes abgeleitet sein. Endlich könnte auch die Unterbrechung der Schußfolge mittels anderer Glieder als der im Abzug angeordneten Auslöseklinke stattfinden. Das dargestellte Ausführungsbeispiel stellt jedoch ein Optimum hinsichtlich der Einfachheit des Aufbaues, des geringen Platzbedarfes und der Zuverlässigkeit dar.It is understood that the invention is not limited to the exemplary embodiment shown, but deviations from it are possible without leaving the scope of the invention. For example, instead of the eccentric, a type of crank drive can be used to drive the pawl, and the pawl and the switching wheel can be loaded by means of springs which are independent of one another. The advancement of the ratchet wheel could also be derived from the cocking movement. Finally, the interruption of the firing sequence could also take place by means of links other than the trigger pawl arranged in the trigger. However, the illustrated embodiment represents an optimum with regard to the simplicity of the structure, the small space requirement and the reliability.
