Patentirt im Deutschen Reiche vom 25. Mai 1878 ab.Patented in the German Empire on May 25, 1878.
Der Apparat besteht in der Hauptsache aus einer communicirenden Röhre, welche an dem einen Ende aus einer Glasröhre hergestellt ist und sich am anderen Ende zu einem Cylinder erweitert, in welchem eine stehende Welle rotirt, die an ihrem unteren Theile eine Schraubenfläche trägt, mittelst welcher eine das Gefäfs zum Theil füllende Flüssigkeit (Glycerin) im Cylinder gehoben und in der Glasröhre , zum Sinken gebracht wird. Die obere Communication zwischen Cylinder und Glasröhre wird durch einen Gummischlauch hergestellt. Ueber und unter der Schraube befinden sich an der Cylinderwandung verticale Wände, welche das Mitdrehen der Flüssigkeit verhindern.The apparatus consists mainly of a communicating tube which is attached to the one end is made from a glass tube and the other end becomes a cylinder in which a standing wave rotates, which at its lower part has a helical surface by means of which a liquid (glycerine) partially filling the vessel in the cylinder lifted and placed in the glass tube to sink. The upper communication between Cylinder and glass tube is made by a rubber hose. Above and below the Screw are on the cylinder wall vertical walls, which allow the rotation of the Prevent liquid.
Die Bewegung der Schraube geschieht mittelst Schnurrad und Leitrollen von der auf ihrer Umdrehungszahl zu untersuchenden Welle aus und wird die Umdrehungszahl von dem Stande der Flüssigkeit in der Glasröhre an einer dahinter angebrachten, durch genaue Versuche festgesetzten Scala direct abgelesen.The screw is moved by means of a cord wheel and guide rollers based on their number of revolutions shaft to be examined and the number of revolutions is determined by the level of the liquid in the glass tube at one behind it attached scale, determined by exact tests, read directly.
Selbstverständlich ist es hierbei nothwendig, immer dasselbe Uebersetzungsverhältnifs von Welle auf Apparat anzuwenden, welches bei Bestimmung der Scala angewendet wurde.Of course it is necessary here to always use the same translation ratio of Apply the wave to the apparatus used to determine the scale.
Durch eine nicht verdunstende Flüssigkeit (Glycerin) und einen möglichst vollkommenen Luftabschlufs ist sowohl einer Verringerung der Flüssigkeitsmenge vorgebeugt, als auch ein innerer gleicher Druck in beiden Röhren erzielt.With a non-evaporating liquid (glycerine) and one that is as perfect as possible Air shut-off prevents both a reduction in the amount of liquid and a internal equal pressure achieved in both tubes.
Die erforderliche Flüssigkeitsmenge kann dadurch controlirt werden, dafs man den Apparat in Ruhe setzt; alsdann mufs der Flüssigkeitsstand in der Glasröhre mit dem Nullstriche der Scala sich in gleicher Höhe befinden. Durch eine in der Cylinderwandung angebrachte, mittelst Schraube verschliefsbare Oeffnung kann der Höhenstand der Flüssigkeit bequem regulirt werden.The amount of liquid required can be controlled by using the apparatus puts in rest; then the liquid level in the glass tube must be marked with the zero line of the Scala are at the same height. By means of a medium installed in the cylinder wall The screw-lockable opening can conveniently regulate the level of the liquid will.
