 Eingriff mit der Schwungradnabe 8 hält, bis die auf der   Stirnnäche   der Hülse angeordnete} einen Viertelkreis bedeckende, ringförmige Erhöhung   20   sich bei dem Hebelzapfen 25 vorbeigedreht hat. Dieser Viertelkreis entspricht der   Transportperiode des Maltheserkrenzes   bei einer Umdrehung der Welle. 



   PATENT-ANSPRÜCHE :
1. Einrichtung zum sofortigen Anhalten kinematographiscber Projektionsapparate während des Filmtransportes, dadurch gekennzeichnet,   dass   nur die drei   Transportzahnrollen   zum Stillstand gebracht werden, wogegen alle anderen rotierenden Teile, wie Schwungrad und Blende, weiter laufen.

 Engagement with the flywheel hub 8 continues until the annular elevation 20, which is arranged on the end face of the sleeve, and covers a quarter circle, has rotated past the lever pin 25. This quarter circle corresponds to the transport period of the Maltheserkrenzes with one revolution of the shaft.



   PATENT CLAIMS:
1. Device for immediately stopping cinematographiscber projection apparatus during film transport, characterized in that only the three transport sprockets are brought to a standstill, while all other rotating parts, such as the flywheel and screen, continue to run.

Claims (1)

2. Einrichtung zum sofortigen Anhalten kinematographischer Projektionsapparate während des Ferntransportes nach Anspruch 1, dadurch gekennzeichnet, dass, um eine zerstörende Wirkung auf die Lagerstellen und Zahnräder zu vermeiden, die auf die Transportrollen arbeitende Hauptwelle ausser Eingriff mit den weiterlaufenden Schwungmassen (Schwungrad und Blende) gesetzt wird. 2. Device for the immediate stop of cinematographic projection apparatus during long-distance transport according to claim 1, characterized in that, in order to avoid a destructive effect on the bearings and gears, the main shaft working on the transport rollers is disengaged from the flywheel masses (flywheel and diaphragm) that continue to run becomes. 3. Eine Vorrichtung nach dem Anspruch 2, dadurch gekennzeichnet, dass das in bekannter Weise von der Blendenwelle mittels Kegelräder angetriebene Schwungrad lose auf der Hauptwelle angeordnet ist und auf der entgegengesetzten Seite mit einer auf dieser Welle, zwecks Einund Auskupplung längsverschiebbaren, mit letzterer durch Mitnehmerstifte zwangläufig verbundenen Hülse ein-und ausgekuppelt werden kann. 3. A device according to claim 2, characterized in that the flywheel, driven in a known manner by the diaphragm shaft by means of bevel gears, is loosely arranged on the main shaft and on the opposite side with a longitudinally displaceable on this shaft for the purpose of coupling and decoupling, with the latter by driving pins inevitably connected sleeve can be engaged and disengaged. 4 : Eine Vorrichtung nach dem Anspruch 2, dadurch gekennzeichnet, dass ein von dem Ankerhebel aus betätigter Hebel so lange die Entkupplung verhindernd sich vor die Kupplungs- hülse (9) legt, bis deren dem Umgang der Transportrolle entsprechende, Viertelkreisförmige Erhöhung 26 ihrer Stirnfläche vorüber ist, zum Zwecke, dass die auf die Transportrollen- welle arbeitende Hauptwelle nur während des Stillstandes des Films angehalten werden kann. 4: A device according to claim 2, characterized in that a lever actuated by the armature lever is placed in front of the coupling sleeve (9), preventing the decoupling, until its quarter-circle shape corresponding to the handling of the transport roller Increase 26 of its end face is over, for the purpose that the main shaft working on the transport roller shaft can only be stopped while the film is stationary.
