Description

Verbindung eines kinematographischen Apparates mit einer Sprechmaschine: Die Erfindung betrifft eine Verbindung eines kinematographischen Apparates mit einer Sprechmaschine mittels biegsamer Zugglieder, die gestattet, daß beide Apparate synchron arbeiten, so daß die Bewegungen der Personen zugleich mit den Worten, dem Gesang und der begleitenden Musik wiedergegeben werden.Connection of a cinematographic apparatus with a speaking machine: The invention relates to a connection of a cinematographic apparatus with a Talking machine by means of flexible tension members, which allows both devices to be synchronized work so that the movements of the people coincide with the words and the singing and the accompanying music.

Um die optische Reproduktion mit der akustischen verbinden zu können, ist es unerläßlich, die Sprechmaschine in die Nähe der Projektionswand zu bringen, während der Projektionsapparat ziemlich weit von der Wand entfernt aufgestellt ist. Hierin liegen die Hauptschwierigkeiten der vollkommen genauen Verbindung beider Maschinen, die bisher meistens nur durch ein einfaches Zugglied oder einen Riemen bewirkt wurde. .In order to be able to combine the optical reproduction with the acoustic, it is essential to bring the speaking machine close to the projection screen, while the projector is placed quite far from the wall. This is where the main difficulty of the perfectly precise connection of the two lies Machines, which up to now mostly only have a simple tension member or a belt was effected. .

Das Verbindungssystem gemäß der Erfindung, das diese Schwierigkeiten beseitigt und ein synchrones Zusammenarbeiten beider Apparate gestattet, ist aus der Zeichnung ersichtlich. i bezeichnet den Projektionsapparat und 2 die Sprechmaschine. Die beiden Apparate besitzen je Eine Kurbelwelle 3 bzw. 3a, die drei um i2o° zueinander versetzte Kurbeln aufweist. Die Zapfen der Kurbeln sind durch Schnüre 4, 4a, 46 miteinander. verbunden, die durch den Saal über Rollen fi laufen. Abb.2 zeigt die um 12o° versetzte Anordnung der Kurbeln und erläutert, daß, wenn einer der beiden Apparate sich dreht, die Schnüre, die alternativ arbeiten, den anderen Apparat zwingen so zu arbeiten, als wenn beide nebeneinanderstehend miteinander verbunden wären.The connection system according to the invention, which these difficulties eliminated and a synchronous cooperation of both devices is allowed can be seen in the drawing. i denotes the projection apparatus and 2 the speaking machine. The two apparatuses each have a crankshaft 3 or 3a, the three at i2o ° to each other has offset cranks. The pins of the cranks are secured by cords 4, 4a, 46 together. connected, which run through the hall on rollers fi. Fig.2 shows the 12o ° offset arrangement of the cranks and explains that if one of the two Apparatus turns, the cords that work alternately force the other apparatus to work as if the two were connected side by side.
