Description
Die Erfindung betrifft einen kineniatographischen Apparat, bei dem die Filmspulen derart auf einer Achse nebeneinander angeordnet sind, daß sie von einer Seite aus auf die Achse aufgesteckt und wieder entfernt werden können. Bei derartigen Filmspulenanordnungen besteht der Übelstand, daß die Filmspulen bei der Filmab- und -aufwicklung zusammenstoßen, wenn sie nicht durch ein ίο zwischen den beiden Filmspulen angebrachtes Organ auseinandergehalten werden.The invention relates to a kineniatographic apparatus in which the film spools are arranged on an axis next to each other that they are from one side on the axle can be attached and removed again. In such film spool assemblies There is the disadvantage that the film spools collide during the unwinding and winding up of the film if they are not through ίο attached between the two film spools Organ are kept apart.
Im nachfolgenden ist in' einem Ausführungsbeispiel eine Einrichtung beschrieben und in der Zeichnung im Schnitt dargestellt, bei der das Zusammenstoßen der beiden Filmspulen« und b während des Betriebs durch ein innerhalb der Filmspulenachse c beweglich angeordnetes Organe?, welches von der dem Filmspulenantrieb e gegenüberliegenden Seite aus zu betätigen ist, verhindert wird. Die Betätigung des Organs d kann z. B. zwangläufig beim Aufstecken der äußeren Filmspule ö erfolgen, am zweckmäßigsten aber durch den Mitnehmer/ der äußeren FiIm- spuleb. Das Organe! ist in dem verlängerten Schlitzg des Mitnehmers/ gelagert, und zwar so, daß es geschwenkt werden kann. Die Verbindung von Mitnehmer/ und Organe erfolgt unmittelbar durch Zahnung der beiden Teile. Das Betätigungsorgan d ist aus Flachmaterial hergestellt und an seinem Ende winklig abgebogen. Seine Bewegung wird durch einen Anschlag begrenzt, der aus einem in der Filmspulenachse befestigten Stift i besteht, welcher in eine Öffnung h des Betätigungsorgans d greift. Das letztere wird ferner an seiner Stirnseite von einem federnden Stifte beeinflußt, so daß es durch, diesen in der jeweiligen Lage festgehalten wird. Beim Aufstecken der Filmspulen befindet sich der wirksame Teil des Organs d innerhalb der Filmspulenachse, so daß die beiden Filmspulen ungehindert aufgesteckt werden können. Beim Umklappen des Mitnehmers/, der gleichzeitig die Filmspule δ vor dem Herabgleiten von der Fihnspulenachsec schützt, wird der umgebogene Teil des Organs d zwischen die benachbarten Wandungen der beiden Filmspulen« und b gebracht, so daß diese stets um die Breite des umgebogenen Teils voneinander getrennt sind und sich, nicht berühren1 können.In the following, a device is described in 'one embodiment and shown in section in the drawing, in which the collision of the two film reels "and b during operation by an organ movably arranged within the film reel axis c, which is from the side opposite the film reel drive e is to be actuated is prevented. The operation of the organ d can, for. B. inevitably take place when attaching the outer film reel ö, but most expediently by the driver / the outer film reel b. The organs! is in the elongated slot g of the driver / mounted in such a way that it can be pivoted. The connection of the driver / and organs takes place directly through the toothing of the two parts. The actuator d is made of flat material and bent at an angle at its end. Its movement is limited by a stop which consists of a pin i which is fastened in the film reel axis and which engages in an opening h of the actuating element d. The latter is also influenced on its front side by a resilient pin, so that it is held in the respective position by this. When the film reels are attached, the effective part of the organ d is located within the axis of the film reel, so that the two film reels can be attached unhindered. When the driver /, which at the same time protects the film reel δ from sliding down from the fihnspulenachsec, is folded over, the bent part of the organ d is brought between the adjacent walls of the two film reels and b so that they are always separated from one another by the width of the bent part and each other, cannot touch 1 .
