Description
Bei den kinematographischen Vorführungsapparaten erfolgt der Wechsel des Filmbildes durch das sogenannte Malteserkreuz. Es ist bekannt, daß die Stiftscheibe bei Eindringen in die Einschnitte des Malteserkreuzes immer einen gewissen metallischen Schlag verursacht. Die Schlaggeräusche wirken aber störend auf das lebende Lichtbild. Man hat schon vielfach versucht, durch verschiedeneIn the case of the cinematographic projection apparatus, the film image is changed through the so-called Maltese cross. It is known that the pin washer when penetrated always causes a certain metallic impact in the incisions of the Maltese cross. However, the impact noises have a disruptive effect on the living light image. One has tried many times, through different ones
ίο Konstruktionen des Malteserkreuzes die Schlaggeräusche zu beseitigen, aber man hatte bis heute keinen Erfolg damit.ίο Constructions of the Maltese Cross the To eliminate knocking noises, but to date it has had no success.
Nach der Erfindung werden diese metallischen Schlaggeräusche dadurch vollkommen beseitigt, daß Schlitze und Sperrbogen des Malteserkreuzes aus einem nicht metallischen Körper, wie Fiber, Rohhaut ο. dgl., hergestellt sind, so daß ein metallischer Schlag überhaupt nicht stattfinden kann.According to the invention, these metallic impact noises are thereby perfect eliminates the need for slots and locking arches of the Maltese cross from a non-metallic Body, such as fiber, rawhide ο. Like., Are made, so that a metallic impact cannot take place at all.
Drei Ausführungsformen des Erfindungsgegenstandes sind in der Zeichnung dargestellt, und zwar zeigen:Three embodiments of the subject matter of the invention are shown in the drawing, namely show:
Fig. i, 3 und 5 teil weisen Längsschnitt, Fig. 2, 4 und 6 Stirnansichten.Fig. I, 3 and 5 partially have longitudinal section, Fig. 2, 4 and 6 end views.
Fig. ι und 2. Das Fiberkreuz α wird an der Stirnseite des Metallkreuzes b, welches mit der Achse c aus einem Stück besteht, mittels Schrauben d o. dgl. befestigt. Das Fiberkreuz α ist etwas größer wie das Metallkreuz b, damit die Stiftscheibe mit dem Metall nicht in Berührung kommt. Bei einem nur von einer Seite in die Schlitze eingreifenden Schaltstift kann das Fiberkreuz auch an der Stirnseite einer vollen runden Scheibe befestigt sein.Fig. 1 and 2. The fiber cross α is attached to the end face of the metal cross b, which consists of one piece with the axis c , by means of screws d or the like. The fiber cross α is slightly larger than the metal cross b so that the pin washer does not come into contact with the metal. In the case of a switch pin engaging the slots from only one side, the fiber cross can also be attached to the end face of a full round disc.
Fig. 3 und 4. Ausführungsform besteht darin, daß das Fiberkreuz e zwischen zwei Flanschen/ und g festgehalten wird. Die Stifte h verhindern das Kreuz am Verdrehen.Fig. 3 and 4th embodiment is that the fiber cross e is held between two flanges / and g . The pins h prevent the cross from twisting.
Fig. 5 und 6. Ausführungsform besteht darin, daß das Fiberkreuz i zwischen zwei Metailkreuzen k und I mittels Schrauben» zusammengehalten wird. Die Metallkreuze k und I geben dem Fiberkreuz einen festen Halt und sind etwas kleiner gehalten, damit sie mit dem Metall der Einzahnscheibe nicht in Berührung kommen.5 and 6th embodiment consists in that the fiber cross i is held together between two metal crosses k and I by means of screws. The metal crosses k and I give the fiber cross a firm hold and are kept slightly smaller so that they do not come into contact with the metal of the single tooth disc.
