Einstellvorrichtung für das Bildband an Kinematographen. Patentiert im Deutschen Reiche vom 8. August 1924 ab. Adjustment device for the picture book on cinematographs. Patented in the German Empire on August 8, 1924.
Die Erfindung betrifft eine Einstellvorrichtung für das Bildband von Kinematographen mittels Schraubendruck. Die bisher bekannt gewordenen Vorrichtungen ähnlicher Art ■j(z.B.nach(Patenteni99i86, 332366 und 379474 sowie engl. Patent 143034) haben sich als nicht zuverlässig erwiesen, weil sich Schaltwalzen in direkter Verbindung mit einer Schraube sehr schwer zum einwandfreien Lauf bringen lassen.The invention relates to an adjusting device for the picture tape of cinematographs by means of screw pressure. The previously known devices of a similar type ■ j (e.g. according to (patents i99i86, 332366 and 379474 as well as engl. Patent 143034) have not proven to be reliable because shift drums In direct connection with a screw, it is very difficult to get it to run properly.
Nach der Erfindung ist die Schaltroüe und das Malteserkreuz starr mit der Achse verbunden, -Die Achse dagegen ist in zwei Teile zerlegt, und diese sind mittels einer verstellbaren Kupplung verbunden. Das Kupplungselement ist in die hohle Achse verlegt und wird mittels einer Stange zentral betätigt. Die Kupplung ist als Lagerwelle ausgebildet. In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt. Darin sind 4 und 5 die beiden Achsenteile, auf welche das Kreuz 6 und die Schaltwelle 8 fest aufgekeilt sind. Die Verdickungen 4 und 5 stellen eine hohle Schraubenkupplung dar, eine Hälfte links, die andere rechts drehend. Die Kupplungsstange 7 trägt entsprechende Schraubenstücke. Wird die Stange hin und her geschoben, so versetzen sich die Achshälften gegeneinander. Durch die Anordnung von links und rechts drehenden Schrauben wird der Verdrehungswinkel verdoppelt zur Verminderung des Hubes. Die Kupplungseinrichtung ist in 2 gelagert, wodurch genaues Laufen der Achsenhälften gesichert ist. Die Kupplungsstange 7 reicht durch die Lagerstelle 3 nach außen, wo die Stange mit einem Ansatz 13 versehen ist und sich in der Führungsschraube 11 drehen kann, die am Drehen durch zwei Stifte 12 verhindert ist. Die Schraubenmutter 14 ist unter dem Ring 9 drehbar gelagert. Mittels des Knopfes io, welcher mit der Mutter 14 fest verbunden ist, ist diese links und rechts drehbar, wodurch die Einstellkupplung betätigt wird.According to the invention, the Schaltroüe and the Maltese cross are rigidly connected to the axis, -The axis, on the other hand, is divided into two parts, and these are adjustable by means of one Coupling connected. The coupling element is laid in the hollow axis and is operated centrally by means of a rod. The coupling is designed as a bearing shaft. An exemplary embodiment of the subject matter of the invention is shown in the drawing. 4 and 5 are the two axle parts on which the cross 6 and the control shaft 8 are attached are firmly wedged. The thickenings 4 and 5 represent a hollow screw coupling one half turning to the left, the other half turning to the right. The coupling rod 7 carries corresponding Screw pieces. If the rod is pushed back and forth, the axle halves move against each other. By arranging left and right turning screws, the angle of rotation is doubled to Reduction of the stroke. The coupling device is mounted in FIG. 2, whereby more precise Running of the axle halves is secured. The coupling rod 7 extends through the bearing point 3 to the outside, where the rod is provided with a shoulder 13 and is in the guide screw 11 can rotate, which is prevented from rotating by two pins 12. the Screw nut 14 is rotatably mounted under ring 9. Using the io button, which is firmly connected to the nut 14, this is rotatable left and right, whereby the Adjustment clutch is operated.
