KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Erfindung betrifft ein Verfahren zur Aufnahme von Landschaftsbildern mittels
eines im wesentlichen aus zwei Spiegeln bestehenden Zeichenapparates. Gegenüber den
bisher bekannten Methoden besteht das Verfahren nach vorliegender Erfindung darin, daß
auf dem Bildspiegel ein mit der Zeichnung zu versehendes durchsichtiges Zeichenblatt (Gelatine
oder Glimmerblättchen) gelegt wird, oder daß gegebenenfalls der Bildspiegel selbst, wenn
für denselben ein Material, auf welchem gezeichnet werden kann, wie z. B. Glimmer, benutzt
wird, als Zeichenfläche dient.
• Ein zur Ausführung dieses Verfahrens geeigneter, auf dem an sich bekannten Prinzip
der doppelten Spiegelung beruhender Apparat ist auf beiliegender Zeichnung schematisch
dargestellt.The invention relates to a method for recording landscape images by means of a drawing apparatus consisting essentially of two mirrors. Compared to the previously known methods, the method according to the present invention consists in that a transparent drawing sheet (gelatine or mica flakes) is placed on the image mirror to be provided with the drawing, or that, if necessary, the image mirror itself, if for the same a material on which to be drawn can, such as B. mica, is used, serves as a drawing surface.
• An apparatus suitable for carrying out this process and based on the principle of double reflection, which is known per se, is shown schematically in the accompanying drawing.
Der Objektspiegel α ist mit dem hölzernen Rahmen des Bildspiegels b durch Lenker c und d derart verbunden, daß die beiden Spiegel unter einem beliebigen Winkel zueinander eingestellt und durch Druckschrauben o. dgl. in der gewünschten Stellung festgehalten werden können.The object mirror α is connected to the wooden frame of the image mirror b by handlebars c and d in such a way that the two mirrors can be set at any angle to one another and held in the desired position by pressure screws or the like.
Bei Benutzung der Vorrichtung wird der Bildspiegel entsprechend auf die Kniee, auf den Boden oder auf einen Tisch gelegt. Die Einstellung der beiden Spiegel zueinander findet derart statt, daß das von dem darzustellenden Gegenstand 0 u im Spiegel α entstandene Bild ο1 u1 im Spiegel b ein Bild ο2 u2 erzeugt, das, von e aus gesehen, auf dieser Spiegelfläche als Bild ο3 u3 nachgezeichnet werden kann. Um dies auszuführen, wird auf den Bildspiegel ein durchsichtiges Zeichenblatt (Gelatine oder Glimmerblättchen) gelegt. Selbstverständlich könnte auch, wie bereits erwähnt, als Bildspiegel ein spiegelndes Material, auf welchem gleichzeitig gezeichnet werden kann, z. B. ein Glimmerblatt 0. dgl., benutzt werden.When using the device, the image mirror is placed on your knees, on the floor or on a table. The adjustment of the two mirrors to one another takes place in such a way that the image ο 1 u 1 created by the object to be represented 0 u in the mirror α creates an image ο 2 u 2 in the mirror b , which, seen from e , is an image on this mirror surface ο 3 u 3 can be traced. To do this, a transparent sheet of drawing (gelatine or mica flakes) is placed on the picture mirror. Of course, as already mentioned, a reflective material could also be used as the image mirror, on which one can draw at the same time, e.g. B. a mica sheet 0. Like., Can be used.
Um beim Zeichnen naher Gegenstände trotz des steilen Winkels, den beide Spiegel zueinander einnehmen, einen Vergleich von Objekt und Bild zu ermöglichen, kann als Objektspiegel eine durchsichtige spiegelnde Glasplatte benutzt werden.To be able to draw close objects despite the steep angle of both mirrors to each other, to enable a comparison of object and image, can be considered as Object mirror a transparent reflective glass plate can be used.
