Description

Gegenstand der Erfindung ist eine verbesserte Ausführungsform der Verschlußscheibe für Vorführungskinematographen nach Patent 359407.The invention relates to an improved embodiment of the closure disc for demonstration cinematographs according to patent 359407.

Die Kinoverschlußscheibe ist von einem T-förmigen Leichtmetallring 3 umgeben, auf dessen Steg auf den Strecken A längs der Symmetrielinie Schlitze eingefräst sind. In diese Schlitze A werden die Abdeckflügel M The cinema shutter disk is surrounded by a T-shaped light metal ring 3, on the web of which slots are milled along the lines A along the line of symmetry. The cover wings M are in these slots A

A sliding of the frosted glass wing M into the web of the 'T-shaped light metal ring 3 side milled slots A is prevented by the small threaded screws s 1 . The T-shaped metal ring 3 is designed in such a way that it completely absorbs the centrifugal forces that arise during rotation, so that the frosted glass panes M are not stressed in any way and are consequently protected from breakage.
