Description

Durch diese sichere ' und schnelle Auswechselbarkeit der Kassetten wird ermöglicht, rasch und leicht mehrere gleiche Vergrößerungen herzustellen. Ein weiterer Vorteil ist, daß Dunkelkammer und Vergrößerungsraum getrennt sein können.This safe and quick interchangeability of the cassettes enables quickly and easily produce several equal enlargements. Another advantage is that darkroom and enlargement room can be separated.

Verstellbarer Doppelrahmen für Vergrößerungen, dadurch gekennzeichnet, daß der innere, verschiebbare Rahmen (b) mit Nuten zum Einschieben einer Kassette und mit einer in die Kassettenbahn hineinragenden, in beliebiger Höhe auf einer Stange (g) feststellbaren Muffe i versehen ist.Adjustable double frame for enlargements, characterized in that the inner, sliding frame (b) is provided with grooves for inserting a cassette and with a sleeve i which protrudes into the cassette track and can be fixed at any height on a rod (g).

Hierzu 1 Blatt Zeichnungen.1 sheet of drawings.

Claims (1)

Patent-Anspruch :Patent claim: Nuten in der Längsrichtung, so daß die Kassette beliebig verschoben werden kann. Um nun eine Begrenzung der Verschiebung der Kassette zu erreichen, ist am Rahmen b eine in zwei Lagern h ruhende, runde Stange g angeordnet, auf der verschiebbar eine durch eine Flügelschraube k feststellbare Muffe i sitzt. Die Muffe, i ist, wie aus der Zeichnung ersichtlich, derart ausgebildet, daß sie unter die Kassette reicht. Es wird dadurch ermöglicht, daß die Kassette c durch die Muffe i in jeder beliebigen Lage eingestellt werden kann, so daß bei Wiederholungen von Vergrößerungen die Kassette wieder auf denselben Platz zu stehen kommt wie das erste Mal. ■Grooves in the longitudinal direction so that the cassette can be moved as desired. In order to limit the displacement of the cassette, a round rod g resting in two bearings h is arranged on the frame b , on which a sleeve i which can be locked by a wing screw k is slidably seated. As can be seen from the drawing, the sleeve, i, is designed in such a way that it extends under the cassette. This enables the cassette c to be set in any desired position by means of the sleeve i , so that when enlargements are repeated, the cassette comes to the same place as the first time. ■
