KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Bei Meßgeräten, ζ. B. Kraftmessern, die mit hydraulisch - volumetrischer Auswertung der Ergebnisse und Strichablesung arbeiten, wurden bisher Schauröhren aus Glas angewandt, die als Bestandteile von Apparaten schwereren Gewichts zumal auf dem Transport leicht dem Bruch ausgesetzt waren.For measuring devices, ζ. B. Force gauges with hydraulic - volumetric evaluation of the Results and line reading work, viewing tubes made of glass were previously used, the heavier weight components of apparatuses, especially those that are easy to transport were exposed to breakage.
Bei Beförderung z. B. mit der Bahn konnte man sich durch Abschrauben der Rohre undWhen transporting z. B. with the train you could by unscrewing the pipes and
ίο Anschrauben an Ort und Stelle behelfen, was auch Entleeren und Wiederfüllen der Meßflüssigkeit notwendig machte.ίο screwing in place help what also made emptying and refilling of the measuring liquid necessary.
Abgesehen von der hierin liegenden Umständlichkeit setzt aber das Dichten des Rohres wegen der Forderung absoluter Dichtheit genaue Kenntnis der störenden Erscheinungen voraus, die sich im Falle von Undichtheiten einstellen, sowie die völlige Beherrschung der abhelfenden Mittel.Apart from the inconvenience involved, the sealing of the pipe is important due to the requirement of absolute tightness, precise knowledge of the disturbing phenomena ahead, which arise in the event of leaks, as well as complete control of remedial means.
Überdies erhöht wiederholtes An- und Abschrauben des Rohres die Gefahr der Beschädigung durch das Werkzeug.In addition, repeated screwing and unscrewing of the pipe increases the risk of damage through the tool.
Die Verwendung anderer durchsichtiger Stoffe großer Zähigkeit, wie z. B. ZelluloidThe use of other transparent materials of great toughness, such as B. celluloid
u. dgl., hat neben der Schwierigkeit der Herstellung enger glatter Bohrungen den Nachteil der leichten Verletzbarkeit der inneren Wandungen, was das Reinigen sehr erschwert.and the like, has the disadvantage, in addition to the difficulty of producing narrow, smooth bores the easy vulnerability of the inner walls, which makes cleaning very difficult.
Bei vorliegender Erfindung wird ein gedrungenes Glasrohr 1 von kleiner Abmessung und einfachster Form in eine Fassung 2, z. B. aus Eisen, eingekittet, auf die ein Zelluloidaufsatz 3 aufgeschrumpft wird.In the present invention, a compact glass tube 1 of small size and simplest form in a version 2, z. B. made of iron, cemented onto which a celluloid attachment 3 is shrunk on.
Eine Beeinträchtigung der Beobachtungsschärfe wird durch Wahl dünner Wandstärken oder Einarbeitung eines Fensters vermieden.The sharpness of observation is impaired by choosing thin wall thicknesses or incorporation of a window avoided.
Das Aufschrumpfen des Zelluloids auf Fassung 2 und obere Fläche des Glasrohres 1 geschieht unter Ausnutzung der Eigenschaft aufgeweichten Zelluloids, beim Erstarren sich zusammenzuziehen, derart, daß die zusammengefügte Vorrichtung in Azeton o. dgl. kurze Zeit eingetaucht und trocknen gelassen wird. Nach dem Verdunsten der Flüssigkeit hat sich das Zelluloid innig an alle Teile angeschmiegt. The shrinking of the celluloid onto the socket 2 and the upper surface of the glass tube 1 happens using the property of softened celluloid when solidifying itself to contract so that the assembled device in acetone o. The like. Short Time is immersed and allowed to dry. After the liquid has evaporated the celluloid clings closely to all parts.
