Description

Die Erfindung betrifft eine Verbesserung am Gegenstand des Patentes 403156, und zwar insbesondere des dritten Anspruches.The invention relates to an improvement on the subject matter of patent 403156, namely in particular of the third claim.

Gemäß diesem Anspruch wird die Ver-Schiebebewegung der Kupplungsmuffe mittels eines nachgiebigen oder starren Gestänges auf eine Kupplungsscheibe übertragen, welche die Mitnahme oder Freigabe der lose auf ihrer Welle sitzenden Fortschaltrolle herbeiführt.According to this claim, the displacement movement of the coupling sleeve is by means of a flexible or rigid linkage transferred to a clutch disc, which the Brings about the entrainment or release of the progressive roller loosely seated on its shaft.

Die Erfindung bezweckt eine weitgehende Vereinfachung dieser Einrichtung dadurch, daß die auf der Schaltrollenwelle angebrachten Antriebe der Filmtrommel und der sonstigen bei der Vorführung beteiligten Mechanismen, Verschluß usw., samt der Schaltrolle bei Verschiebung der Kupplungsmuffe gleichzeitig und direkt aus- oder eingeschaltet werden.The invention aims to simplify this device to a large extent by that the drives of the film drum mounted on the pulley shaft and the other drives involved in the presentation Mechanisms, lock, etc., including the pulley when shifting the coupling sleeve can be switched off or on at the same time and directly.

Die Vorrichtung nach der Erfindung ist in der Zeichnung beispielsweise dargestellt. Auf der Welle e ist, wie im Hauptpatent beschrieben, die Kupplungsmuffe i verschiebbar. Die Verschiebung nach rechts bewirkt die Vorführung, die Verschiebung nach linksThe device according to the invention is shown in the drawing, for example. As described in the main patent, the coupling sleeve i is slidable on the shaft e. The shift to the right causes the presentation, the shift to the left

a5 die Rückrollung des Films. a 5 the rewinding of the film.

Auf der Welle w der Schaltrolle y sitzt mittels der Büchse b das Antriebsrad α für die bei der Vorführung beteiligten Mechanismen, den Verschluß usw. Auf dieser Büchse sitzt lose auch das Antriebsrad« für die untere Filmspule, welches unter Vermittlung des Kegelrades r dlas Antriebsgestänge t dieser Filmspule antreibt.On the shaft of the switching roller y w sits by the rifle b the drive wheel α for the participating at the screening mechanisms, the shutter etc. On this bushing loose also the drive wheel "for the lower film spool which r through the intermediary of the bevel gear sits DLAs drive linkage t this film reel drives.

Wird nun die Kupplung zur Rückrollung nach links verschoben, dann erfolgt gleichzeitig und direkt die Ausschaltung der Schaltrolle, der Filmspule und der sonst an der Vorführung beteiligten Mechanismen.If the clutch is now shifted to the left to roll back, it takes place simultaneously and the switching off of the pulley, the film reel and the rest of the show involved mechanisms.
