Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Durch die Patentschrift 81380 ist eine photographische Doppelcarnera bekannt geworden, deren Theile, von welchen der eine zum Einstellen des Bildes und der andere zum Photographiren dient, so angeordnet sind, dafs sie sich beide, wenn sie ausgeschoben oder mehr oder weniger zusammengezogen sind, auf das Object richten.By the patent 81380 is a photographic Doppelcarnera have become known, their parts, one of which is for setting of the picture and the other for photographing, are arranged so that they are both, when they are pushed out or more or less contracted, to the Align the object.

Diese verschiedenen Richtungen der beiden Cameras werden bei diesem Apparate durch eine wenig einfache Anordnung von Schlitzführungen erzielt, durch welche sehr oft die Bewegung aufserordentlich erschwerende Klemmungen hervorgerufen werden.These different directions of the two cameras are carried out with this apparatus achieved a not very simple arrangement of slot guides, through which very often the Movement extremely aggravating clamps are caused.

Um diesen Uebelstand zu vermeiden, wurde die auf beiliegender Zeichnung dargestellte sehr einfache Einrichtung getroffen. Die hinteren Führungsplatten ρ der beiden Cameras sind mit den an der Grundplatte in der Querrichtung geführten Zahnstangen ^1 versehen, von welchen die eine an der einen und die andere an der anderen Seite der Achse α liegt und in das kleine Rädchen r1 auf derselben eingreift. Die beiden Objectivhalter 0 der Cameras sind an einer Querschiene s gelenkig angebracht, welche mit der an der Grundplatte in der Längsrichtung geführten Stange % verbunden ist. Diese greift in ein gröfseres, auf der Achse angebrachtes Rad r ein. Wird die Zahnstange mit der Querstange durch das Rad r nach vorn geschoben, so werden die beiden Cameras verlängert und also auf eine kürzere Distanz eingestellt. Hierbei werden gleichzeitig die Cameras hinten durch das kleinere Zahnrad r1 etwas aus einander geschoben, so dafs sich beide gleichzeitig auf das näher befindliche Object richten. Der Antrieb der Achse α erfolgt durch den Knopf Ar, welcher unten mit einem Kettenrädchen k1 versehen ist. Von diesem ist eine Kette k2 nach einem auf der Achse α angebrachten Kettenrädchen r2 geführt. ' In order to avoid this inconvenience, the very simple arrangement shown in the accompanying drawing was made. The rear guide plates ρ of the two cameras are provided with the racks ^ 1 guided on the base plate in the transverse direction, one of which lies on one side and the other on the other side of the axis α and engages in the small wheel r 1 on the same . The two objective holders 0 of the cameras are attached in an articulated manner to a transverse rail s , which is connected to the rod% guided in the longitudinal direction on the base plate. This engages in a larger wheel r mounted on the axle. If the rack with the cross bar is pushed forward by the wheel r , the two cameras are lengthened and therefore set to a shorter distance. At the same time, the cameras at the rear are pushed a little apart from one another by the smaller gear wheel r 1 , so that both are directed simultaneously at the object that is closer. Axis α is driven by button Ar, which is provided with a chain wheel k 1 at the bottom. From this a chain k 2 after on the axis of α-mounted chain wheels r 2 out. '
