KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Erfindung betrifft einen aus zwei gleichen Apparaten bestehenden Kinematographen, bei dem die Achsen der beiden Objektive auf einen bestimmten Punkt einstellbar und die Verschlüsse und Fortschaltvorrichtungen miteinander zwangläufig verbunden sind.The invention relates to a cinematograph consisting of two identical apparatuses which the axes of the two lenses can be adjusted to a certain point and the Locks and indexing devices are inevitably connected to one another.
Doppelkinematographen mit einer gemeinsamen Achse für den Antrieb sind bekannt und finden u. a. zu dem Zwecke Verwendung,Double kinematographs with a common axis for the drive are known and find i.a. for the purpose of use,
ίο das bei Einzelapparaten leicht entstehende Flimmern der Bilder zu vermeiden.ίο that which arises easily with individual devices Avoid flickering of the images.
Da sowohl bei der Aufnahme als auch bei der Wiedergabe der Bilder es erforderlich ist, den Schnittpunkt der optischen Achsen der beiden Apparate zu verschieben, also den optischen Achsen verschiedene Neigung gegeneinander zu geben sowie den Abstand der Apparate voneinander zu verändern, so wird nach der Erfindung in das zwischen beiden Apparaten liegende Stück der gemeinsamen Achse ein Kardangelenk eingesetzt und die Achse selbst ausziehbar eingerichtet. Es können natürlich auch an Stelle eines zwei Kardangelenke angebracht und das ausziehbare Stück der Achse kann zwischen diese beiden Gelenke gelegt werden. Diese Ausführungsform ist im folgenden beschrieben.Since both when recording and when playing back the images, it is necessary to to move the point of intersection of the optical axes of the two apparatuses, i.e. the optical To give axes different inclinations to each other and to change the distance between the apparatuses, so will according to the invention in the piece of the common between the two apparatuses Axis a cardan joint is used and the axis itself is set up so that it can be pulled out. It can of course also be fitted with two universal joints in place of one and the retractable one Piece of the axle can be placed between these two joints. This embodiment is described below.
Die Zahnräder 4 beider Apparate sind durch die Achse 3 zwangläufig miteinander verbunden. Die beiden zueinander senkrecht stehenden Achsen 1 und 2 nebst zugehörigen Lagern bilden je eines der bekannten Kardanschen Gelenke. Zwischen beiden Gelenken besteht die Achse aus zwei ineinander geführten Rohren 5 und 7, von denen letztgenanntes im ersten liegt und verschiebbar ist. In zwei Längsschlitze 6 des Rohres 5 greift das Rohr 7 mit zwei Zapfen 8 ein, so daß sich beide Rohre zwar um die Schlitzlänge verschieben können, aber auf Drehung starr gekuppelt sind.The gears 4 of both devices are inevitably connected to one another by the axis 3. The two mutually perpendicular axes 1 and 2 together with the associated bearings each form one of the known cardan joints. There is between the two joints the axis of two tubes 5 and 7, one inside the other, of which the latter lies in the first and can be moved. The tube 7 engages in two longitudinal slots 6 of the tube 5 with two pins 8, so that both tubes move by the length of the slot can, but are rigidly coupled to rotation.
