Die vorliegende Erfindung betrifft eine Vorrichtung, um zu prüfen, ob Geschütze richtig auf ein bewegliches Ziel eingestellt worden sind. Die Vorrichtung ist besonders bei Ziel-Übungen und im Manöver anzuwenden, wenn blinde Munition gefeuert wird. Die Einstellung von Visiervorrichtungen auf unbewegliche Ziele hat man bereits dadurch nachgeprüft, daß in der eingestellten Visierlinie ein paralleles Strahlenbündel auf das Ziel geworfen wurde. Seine Lage am Ziele ließ den eingestellten Visierpunkt unmittelbar erkennen. Bei beweglichen Zielen würde es nicht richtig sein, die Visierlinie auf das Ziel zu richten und zur Kontrolle des Treffpunktes einen Lichtstrahl im Augenblick des Abdrückens in der Visierlinie auszusenden, weil das Geschoß erst am Zielort eintrifft, wenn das Ziel sich bereits wieder aus der Visierlinie herausbewegt hat. Der Schütze muß deshalb um einen der Flugzeit des Geschosses entsprechenden Betrag vor das Ziel halten, und das Lichtbüschel muß ausgesendet werden, wenn das Geschoß die mit Hilfe eines Entfernungsmessers festgestellte Strecke bis zum Ziele zurückgelegt hat. Um das Lichtbüschel im richtigen Zeitpunkt aussenden zu können, ist nach vorliegender Erfindung mit dem Zielprüfer ein Zeitmesser verbunden, und zwar ist beispielsweise ein Uhrwerk vorgesehen, welches durch Ziehen am Abzug in Gang gesetzt wird und welches nach einer einstellbaren Zeit (etwa zwischen ¹Z₂₀ und 10 Sekunden) entweder einen Schlagbolzen auslöst, der eine Blitzlichtpatrone entzündet, die das parallele Lichtbündel liefert, oder aber einen Momentverschluß auslöst, der das dauernd erzeugte, aber abgeblendete Lichtbündel nach Ablauf der eingestellten Zeit auf einen Augenblick freigibt. Dieser Lichtblitz wird von einem sich mit dem Ziele (z. B. Flugzeug) bewegenden Beobachter in dem Falle gesehen werden, daß die Visierlinie beim Abkommen auf den Punkt gerichtet war, an dem das Ziel nach Ablauf der Flugzeit des Geschosses sich befindet. Fehler in der eingestellten Entfernung des Zieles können mit der Vorrichtung naturgemäß nicht ermittelt werden. The present invention relates to apparatus for checking that guns have been properly aimed at a moving target. The device is particularly useful for target exercises and maneuvers when blind ammunition is fired. The setting of sighting devices on immovable targets has already been checked by throwing a parallel beam of rays onto the target in the set sighting line. Its position on the target indicated the set sight point immediately. In the case of moving targets, it would not be correct to aim the line of sight at the target and to send a light beam to control the point of impact at the moment of the trigger in the line of sight, because the projectile only arrives at the target location when the target has already moved out of the line of sight again Has. The shooter must therefore stop in front of the target by an amount corresponding to the flight time of the projectile, and the light bundle must be emitted when the projectile has covered the distance to the target determined with the aid of a range finder. In order to be able to emit the light bundle at the right time, a timer is connected to the target tester according to the present invention, for example a clockwork is provided that is started by pulling the trigger and which is set after an adjustable time (e.g. between ¹ Z ₂₀ and 10 seconds) either triggers a firing pin, which ignites a flash cartridge that delivers the parallel light beam, or triggers a momentary shutter, which releases the continuously generated but dimmed light beam for an instant after the set time has elapsed. This flash of light will be seen by an observer moving with the target (e.g. aircraft) in the event that the line of sight was aimed at the point at which the target is after the projectile's flight time has elapsed. Naturally, errors in the set distance of the target cannot be determined with the device.

Die Vorrichtung kann entweder in Verbindung mit einem Geschütz oder unabhängig von einem solchen auf einem Dreifuß einstellbar montiert verwendet werden. Bei der auf der Zeichnung dargestellten Ausführungsform der Erfindung wird eine Blitzlichtpatrone verwendet, die durch einen Schlagbolzen zur Entzündung gebracht wird, wobei der Schlagbolzen durch ein geeignetes Uhrwerk zeitlich eingestellt wird.The device can be used either in conjunction with a gun or independently can be used by such an adjustable stand mounted on a tripod. At the on the embodiment of the invention shown in the drawing, a flash cartridge is used, which is ignited by a firing pin, the firing pin is timed by a suitable clockwork.

Der Apparat ruht auf einem Ständer oder Dreifuß a, ist in der Höhe verstellbar und kann außerdem um eine senkrechte und um eine wagerechte Achse gedreht werden. Das Letzte wird dadurch erreicht, daß das Gestell d mit dem Zapfen c in dem Auflager b drehbar gelagert ist. Dabei erfolgt die Feststellung des Apparates in einer bestimmten Richtung durch Drehen des Armes f¹, der die Spannschraube f anzieht.The device rests on a stand or tripod a, is adjustable in height and can also be rotated around a vertical and a horizontal axis. The latter is achieved in that the frame d is rotatably mounted with the pin c in the support b. The device is locked in a certain direction by turning the arm f ¹ , which tightens the clamping screw f .

passes through a spindle g, which is provided with a knurled head. By turning the head, a gear g ^{2 is set} in motion, which ^{engages in the teeth g 1 of} the rod e and moves the apparatus up and down. The rod e runs in a gap guide g ^{3 of} the support part d. Around the gap guide g ³ , the part holding the spindle g with the gearwheel, which through

ίο the screws g ^{4 are} tightened.

The apparatus is rotated horizontally by a worm spindle h which activates a worm wheel h ¹ . The latter is attached to a support board i and rotates at the upper end of the rod e.

The visor carrier / is attached to the lens frame k with the aid of a strut j ¹ . It has a fixed front ^{sight j 2} and an adjustable visor j ⁸ attached to a horizontal support /. The visor / ³ can be adjusted in a gap guide of a vertical support I ^1.

At the rear end of the support board, a dial m is attached, which is driven by a clockwork within the housing η and which is divided into graduation lines that represent the twentieth part of a second. A pointer m ¹ is attached to the end of the support board to facilitate adjustment of the dial. At the front of the latter there is a worm wheel (step wheel) that rotates with the dial and triggers the ignition device. This consists of the following striking device causing the ignition of the flash cartridge: A lever r resting on the step wheel and rotatably mounted on a support bar s is held in a tensioned position by a spring t. The lever r is connected to a pin p by a rod q (Figs. 3 and 4). When the striking device is triggered, this bolt p releases a pin q ¹ , which in turn triggers a hammer ζ located in a tube u and held in tension against the action of a spring u ^1. The hammer is guided in a gap u ^{2 in} the tube u , snaps up in this guide due to the spring action and ignites a flashlight cartridge ν. This is held in place by a Hebei w carrying a reflector w ^1. To change the cartridge, the lever w is rotated about its pivot point w ^2. After removing the used cartridge and inserting a new cartridge, the lifting lever w is tightened by the cord χ and held on the support f ¹ by a hook y . The flashlight cartridge ν is thus brought into the ignition position.

On the other side of the board i , the lens frame k, in which the lens k ¹ sits, can be adjusted by a spindle k ² on the board i in order to be able to determine the focal length.

As already mentioned, the apparatus can either be operated in the manner described on a Frame or attached to the gun itself. In the latter case, the sighting device would of the gun represent that of the frame. The arrangement can also be taken in such a way that the sighting device of the apparatus housed on a stand is inevitably connected to the sighting device of a gun, so that the light beam to be emitted with each adjustment of the gun's line of sight on the gun remains parallel.

In use, the dial m of the timing device is released by loosening the screw nut m ² . The dial can be set and then cause the Hebei r to trigger its impact mechanism at the appointed time.

The line of sight p, / ³ is always set parallel to the bundle of light to be emitted and, without taking into account any lateral deviation of the projectile, aimed at the point at which, in the view of the shooter, the movable target will be at the target when the projectile hits the target.

At the moment of firing, the hook of the clockwork is released. Since that bundles of parallel or nearly parallel rays generated by the lens only through a very small angle can be seen, must with properly set flight time properly aimed and the angular velocity of the aircraft properly taken into account when the officer on the plane notices the glow of the light. A firing of the gun is not necessary. One need only watch the flashlight signal from the target.
