Vorrichtung zum Verbinden der Enden von breiten Kinofilmen mit mehreren Bildreihen. Patentiert im Deutschen Reiche vom 26. Juni 1920 ab.Device for joining the ends of wide cinema films with several rows of images. Patented in the German Empire on June 26, 1920.

Für diese Anmeldung ist gemäß dem Unionsvertrage vom 2. Juni 1911 die Prioritüt auf Grund der Anmeldung in Großbritannien vom 3. Februar (914 beansprucht. 'According to the Union Treaty of June 2, 1911, priority is due to this application of filing in Great Britain dated February 3 (914 claimed. '

Die Erfindung betrifft eine Vorrichtung zum Verbinden der Enden von breiten Kinofilmen mit mehreren Bildreihen. Erfahrungsgemäß bietet die Verbindung derartiger Filme bisher große Schwierigkeiten, da das übliche Verkleben unter Verwendung von Azeton oder Amylazetat ein Krümmen oder Schrumpfen des Zelluloids bewirkt, wodurch neben der durch das Kleben verursachten Unmöglichkeit der Aufhebung der Verbindung ohne Zerstörung von Teilen des Films ein leichtes Durchlaufen des letzteren durch den Vorführungsapparat sozusagen ausgeschlossen wird. Aus diesem Grunde haben sich die Fachkreise schon lange die Aufgabe gestellt, eine Verbindungsvorrichtung zu schaffen, die neben der leichten Lösbarkeit der Filmenden ein ungestörtes Durchlaufen des Films durch den Ap-■parat ermöglicht. Diese Aufgabe ist gemäß der Erfindung in der Weise gelöst worden, daß an den Filmenden nahe deren Kanten schmale Verbindungsglieder, wie beispielsweise Bolzen und Muttern, Druckknöpfe, Papierklammern u. dgl., angebracht sind, und daß 25- die Endkante des innenliegenden Films konkav zugeschnitten ist. Die Benutzung von Druckknöpfen, Klammern o. ■dgl., zum Verden zweier Teile, auch von Filmen, ist an sich bekannt, weshalb die Erfindung lediglich in der Verbindung dieses Merkmals mit dem konkaven Zuschnitt der Endkante des innenliegenden Films erblickt wird.The invention relates to a device for joining the ends of wide motion picture films with a plurality of rows of images. Experience has shown that the connection of such films has so far presented great difficulties, since the usual gluing using acetone or amyl acetate causes the celluloid to curve or shrink, which, in addition to the impossibility of breaking the connection caused by the gluing, makes it easy to pass through the film without destroying parts of the film the latter is, so to speak, excluded by the demonstration apparatus. For this reason, experts have long set themselves the task of creating a connecting device which, in addition to the easy detachment of the film ends, enables the film to pass through the apparatus without being disturbed. This object has been achieved according to the invention in such a way that narrow connecting members such as bolts and nuts, press studs, paper clips and the like are attached to the ends of the film near their edges, and that the end edge of the inner film is cut to be concave is. The use of pushbuttons, clips or the like for verdening two parts, including films, is known per se, which is why the invention is only seen in the connection of this feature with the concave cut of the end edge of the inner film.

Die Erfindung ist auf der Zeichnung veranschaulicht. Abb. ι ist ein Längsschnitt der Enden eines breiten Films, der gemäß der schaubildlichen Darstellung in Abb. 2 endlos geschlossen ist, und auf dem die Bilder in schraubenförmigen oder parallelen Linien angeordnet sind; Abb. 3 und 4 zeigen abgeänderte Ausführungsformen der Befestigung, und Abb. 5 und 6 sind Draufsichten benachbarter Filmteile.The invention is illustrated in the drawing. Fig. Ι is a longitudinal section of the Ends of a wide film which, as shown in the diagram in Fig. 2, is endless is closed, and on which the images are arranged in helical or parallel lines are; Figures 3 and 4 show modified forms of attachment, and Figures 5 and 6 are plan views of adjacent ones Film parts.

a, ax sind die zu verbindenden Filmenden. a, a x are the ends of the film to be connected.

Diese werden auf zwei Stifte g gesteckt, von denen nur einer dargestellt ist, und die auf einen Grundteil g1 in solchen Abständen angebracht sind, daß sie den Lochungen α4 des Films entsprechen. Wenn auf diese Weise die benachbarten Bilder in ihre genaue Lage gebracht sind, wird nahe jeder Seite der Filmenden ein Loch α2 durch die beiden übereinanderliegenden Enden gemacht. Die Enden werden dann von den Stiften g entfernt und ein Teil b eines Druckknopfes durch jedes Paar der Löcher a2 gesteckt. Dieser Teil b muß genau in den Löchern az passen, damit die Enden in ihren genauen relativen Lagen gehalten werden. Der andere Teil b1 des Druckknopfes wird darm auf jeden Teil b gedrückt und durch Einschnappen festgelegt. Der untere Teil a1 des Films wird konkav beschnitten Λ) versehen, wie dies aus den Abb. 2, 5 und 6 hervorgeht.These are placed on two pins g , only one of which is shown, and which are attached to a base part g 1 at such intervals that they correspond to the perforations α 4 of the film. When the adjacent images are in their correct position in this way, a hole α 2 is made through the two superimposed ends near each side of the film ends. The ends are then removed from the pins g and part b of a push button is inserted through each pair of the holes a 2. This part b must fit snugly in the holes a z so that the ends are held in their exact relative positions. The other part b 1 of the push button is then pressed onto each part b and fixed by snapping into place. The lower part a 1 of the film is trimmed concave Λ ) , as shown in Figs. 2, 5 and 6.

Abb. 3 zeigt einen kleinen Bolzen a mit ?iner Mutter c1 als Verbindungsmittel für die Filmenden a, a1. Fig. 3 shows a small bolt a with an inner nut c 1 as a connecting means for the film ends a, a 1 .

Abb. 4 veranschaulicht eine T-förmige Papierklammer d als Verbindungsmittel. Bei Anwendung der Papierklammern werden die Löcher in dem Film zum Durchlassen der doppelten Metallstärke in Form kleiner Schlitze α·5 ausgeführt, wie dies aus Abb. 6 zu ersehen ist, und die Enden d1 werden dann nach unten gegen den Film umgebogen und, wie in Abb. 4 gezeigt, flach gedrückt.Fig. 4 illustrates a T-shaped paper clip d as a connecting means. When using the paper clips, the holes in the film for the passage of twice the metal thickness are made in the form of small slits α x 5 , as can be seen in Fig. 6, and the ends d 1 are then bent down against the film and, as shown in Fig. 4, pressed flat.
