KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Optische Instrumente, wie Fernrohre u. dgl., sind meist nur mit einem Fadensystem bestimmter Art versehen. Soll nun das Instrument zu einem anderen Zweck benutzt werden, der ein anderes Fadensystem erfordert, oder soll das Fadensystem aus anderen Gründen ausgewechselt werden, so muß das Fernrohr auseinandergenommen werden, um das erforderliche Fadensystem einzusetzen.Optical instruments, such as telescopes and the like, are usually only more specific with a thread system Art provided. Should the instrument now be used for a different purpose that requires a different thread system, or should the thread system consist of others Reasons to be replaced, the telescope must be disassembled in order to to use the required thread system.
ίο Dieses Auswechseln an ein und demselben Instrument sofort und einfach bewirken zu können, bildet den Gegenstand der vorliegenden Erfindung, der darin besteht, daß auf einer in dem Fernrohr o. dgl. gelagerten Walze verschiedene Fadensysteme angeordnet sind, die durch Drehen der Walze mit Hilfe eines außerhalb des Fernrohres vorgesehenen Knopfes o. dgl. nacheinander in die Bildebene gebracht werden können.ίο This replacement on one and the same To be able to effect an instrument immediately and easily forms the subject of the present Invention, which consists in that various thread systems are arranged on a roller mounted in the telescope or the like are provided by rotating the roller with the help of an outside of the telescope Button or the like. Can be brought into the image plane one after the other.
In der Zeichnung ist eine derartige Vorrichtung dargestellt, und zwar in Fig. 1 in Seitenansicht, in Fig. 2 in Oberansicht.In the drawing, such a device is shown, in Fig. 1 in Side view, in Fig. 2 in top view.
Die Walze a, welche auf der Welle b in Lagern c drehbar ist, ist an ihrer Mantelfläche mit einer Reihe von Fadensystemen dx d2 ds a?4 versehen, welche durch Drehen der Walze mit Hilfe eines auf der Welle b aufgesetzten Knopfes o. dgl·, nacheinander in die Bildebene des Fernrohres gebracht werden können. Um das zu benutzende Fadensystem genau in der Bildebene einstellen zu können, ist der Lagerbock in einer Schwalbenschwanzführung h des justierbaren Einsatzstücks i verschiebbar. Ferner ist an einem der Lager eine mit Knöpfen g versehene Einschnappfeder/ vorgesehen, welche das Fadensystem in der erforderlichen Läge festhält.The roller a, which is rotatable on the shaft b in bearings c , is on its outer surface with a series of thread systems d x d 2 d s a? 4 , which can be brought into the image plane of the telescope one after the other by rotating the roller with the aid of a button or the like placed on the shaft b. In order to be able to set the thread system to be used precisely in the image plane, the bearing block can be displaced in a dovetail guide h of the adjustable insert piece i . Furthermore, a snap spring / provided with buttons g is provided on one of the bearings, which holds the thread system in the required position.
Bei der vorliegenden Anordnung, wie sie die Zeichnung darstellt, liegt hinter dem in der Bildebene gelegenen Fadenkreuz ^1 noch das Fadenkreuz d%. Letzteres bleibt aber unsichtbar, da es nicht in der Bildebene liegt.In the present arrangement, as shown in the drawing, the crosshair d % is still located behind the crosshair ^ 1 located in the image plane. The latter, however, remains invisible because it is not in the image plane.
