Description

Es ist bekannt, bei Kinematographen die Schwungmasse, die zum Erzielen eines gleichmäßigen Ganges notwendig ist, als Kulisse zum Steuern des Filmgreifers auszubilden. Die Erfindung betrifft! ein Schaltwerk dieser Gattung, und zwar soll, um das Volumen kinematographischer Apparate möglichst klein zu gestalten, der den Greifer steuernde Exzenter auf der Schiwungmassenachse sowieIt is known, in cinematographs, the flywheel, which is necessary to achieve a uniform Ganges is necessary to train as a backdrop to control the film gripper. The invention concerns! a rear derailleur of this type, and that is supposed to increase the volume To make cinematographic apparatus as small as possible, the eccentric controlling the gripper on the swing mass axis as well

ίο die die Schließbewegung des Greifers verursachende Kulisse auf derselben Schwungmasse angeordnet sein. Durch die Anordnungsweisie der Greifersteuerung wird ein äußerst! geringer Raum beansprucht, sowie eine Vereinfachung des Antriebsmechanismus erzielt.ίο the one causing the closing movement of the gripper Setting be arranged on the same flywheel. Due to the arrangement the gripper control becomes an extremely! takes up little space, as well achieved a simplification of the drive mechanism.

In der Zeichnung ist in Ansicht und Schnitt die Greifersteuerung dargestellt. Diese besteht aus dem auf der Schwungmassenachse a In the drawing, the gripper control is shown in view and section. This consists of the one on the centrifugal mass axis a

so angeordneten Herzexenter b, der den Rahmenteil c, welcher von einer senkrecA angeordneten Schiene d geführt wird, steuert. Die Schiene d ist mit einer zweiten Schiene e, welche in ihrer Längsrichtung verschiebbar ge- · lagert ist, verbunden. An der Schiene e sind as zwei Zapfen i angebracht, die in eine auf der Schwungscheibe f exzentrisch verlaufende Ringwulst (Kulisse g) übergreifen. Bei der Drehung der Schwungscheibe wird der Schiene e eine hin und her gehende Bewegung erteilt, die auf die mit der Schiene e starr verbundene Schiene d in der Weise übertragen wird, daß diese Schiene eine Querbewegung parallel zu sich selbst und ebenfalls in einer zur Fläche der Schwungscheibe parallelen Ebene vollführtl Dadurch wird dem Rahmen c und den mit ihm verbundenen Greiferspitzen neben der auf und nieder gehenden Bewegung noch eine seitliche Bewegung erteilt, durch die die Greiferstifte h zum Ein- und Austreten in die Lochungen des Bildbandes veranlaßt wenden. Da beide Bewegungenthus arranged heart eccentric b, which controls the frame part c, which is guided by a vertically arranged rail d. The rail d is connected to a second rail e, which is mounted displaceably in its longitudinal direction. As two pins i are attached to the rail e , they overlap in an annular bead (gate g) running eccentrically on the flywheel f. During the rotation of the flywheel, the rail e is given a reciprocating motion, which is transmitted to the rail d rigidly connected to the rail e in such a way that this rail has a transverse movement parallel to itself and also in one to the surface of the Flywheel parallel plane thus the frame c and the gripper tips connected to it are given a lateral movement in addition to the up and down movement, which causes the gripper pins h to turn in and out of the perforations of the illustrated book. Since both movements

des Greifers, die Auf- und Abbewegung und die Schließbewegung, parallel zur Ebene der Schwungscheibe erfolgen, wird es ermöglicht, die Schwungscheibe an einer Längswand der Kamera anzuordnen, wodurch die Dicke der Kamera ganz bedeutend verringert wird.of the gripper, the up and down movement and the closing movement, parallel to the plane of the Flywheel done, it is made possible to attach the flywheel to a longitudinal wall of the Arrange camera, whereby the thickness of the camera is reduced very significantly.
