KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Zur Einstellung auf bei künstlicher Beleuchtung zu photographierende Objekte verwendet man bereits Lichtquellen, vor denen undurchsichtige Flächenfiguren o. dgl. angebracht sind.Used for setting on objects to be photographed under artificial lighting you already have light sources in front of which opaque surface figures or the like are attached.
So ist z. B. eine Vorrichtung bekannt, die aus einem runden Blech mit ausgestanztem Kreuz und hinterlegten! Mattpapier besteht und zum Aufstecken auf eine Kerze eingerichtet ist. Auch Laternen werden für diesen Zweck benutzt, deren eine Scheibe aus Milchglas besteht, auf dem undurchsichtige Figuren angebracht sind.So is z. B. a device is known which consists of a round sheet metal with a punched cross and deposited! Matt paper and is set up to be attached to a candle. Lanterns are also used for this purpose, one of which is made of frosted glass, on which opaque figures are attached.
Gegenstand vorliegender Erfindung bildet nun eine Vorrichtung, welche bei den bekannten elektrischen Taschenlampen Verwendung finden soll. Diese liefern vor allen Dingen ein besonders helles Licht.The present invention now forms a device which in the known electric flashlights should be used. Above all, these provide a particularly bright light.
Auf beiliegender Zeichnung ist die Vorrichtung dargestellt, und zwar zeigen Fig. 1 und 2 die elektrische Taschenlampe mit der Vorrichtung in Vorder- und Seitenansicht, Fig. 3 eine Draufsicht, Fig. 4 einen Schnitt durch eine besondere Ausführungsform, Fig. 5 eine Draufsicht dieser Form.The device is shown in the accompanying drawing, specifically FIGS. 1 and 2 the electric flashlight with the device in front and side views, Fig. 3 a Top view, FIG. 4 a section through a particular embodiment, FIG. 5 a top view this shape.
Die elektrische Taschenlaterne α bekannter Art ist vor der Glühlampe mit einer Linse b versehen. Auf diese Lampe wird eine Kappe c aufgeschoben, die durch federnde Schenkel d gehalten wird. Über der Lampenlinse b befindet sich eine gewölbte Kuppe e, die im Gegensatz zu den übrigen Teilen der Kappe c aus lichtdurchlässigem Material, z. B. Celluloid, besteht. Auf dieser Kuppe e ist ein dunkelgefärbter Stern f 0. dgl. vorgesehen.The electric pocket lantern α of known type is provided with a lens b in front of the incandescent lamp. A cap c, which is held by resilient legs d, is pushed onto this lamp. Above the lamp lens b there is an arched dome e which, in contrast to the other parts of the cap c, is made of translucent material, e.g. B. celluloid. A dark-colored star f 0. The like is provided on this tip e.
Bei der Aüsführungsform gemäß den Fig. 1 bis 3 ist die ganze Kappe aus einem einheitlichen Material, z. B. Celluloid, hergestellt. Bei der in den Fig. 4 und 5 dargestellten Ausführungsform ist die aus durchsichtigem Celluloid bestehende Kuppe e in einen Ausschnitt der aus Metall o. dgl. hergestellten Kappe c eingesetzt.In the embodiment according to FIGS. 1 to 3, the entire cap is made of a single material, e.g. B. celluloid. In the embodiment shown in FIGS. 4 and 5, the cap e consisting of transparent celluloid is inserted into a section of the cap c made of metal or the like.
Die Vorrichtung ist sehr klein und schnell aufzustecken. Die Lichtstärke der elektrischen Lampe erleichtert ein scharfes Einstellen auf der Mattscheibe.The device is very small and quick to attach. The light intensity of the electric The lamp makes it easier to focus on the focusing screen.
