KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. Um eine möglichst empfindliche Uebertragung einer zu messenden Verschiebung auf die Zeigerachse zu erhalten, ist in einem beliebigen, der Empfindlichkeit entsprechenden Abstand zur Zeigerachse ein dünner Faden f parallel zu dieser geführt. Die Enden desselben liegen an den Stiften s s fest. An diesen Faden f greift das Uebertragungsglied g an, das andererseits mit dem beweglichen Theil des Mefsgeräthes, dessen Verschiebung gemessen werden soll, in Verbindung steht.In order to achieve the most sensitive transfer of a displacement to be measured to the pointer axis, a thin thread f is guided parallel to the pointer axis at any distance from the pointer axis that corresponds to the sensitivity. The ends of the same are fixed to the pins ss. This thread f is engaged by the transmission element g , which on the other hand is connected to the movable part of the measuring device, the displacement of which is to be measured. Dadurch, dafs g mit f fest verbunden ist, wird bei der Drehung der Zeigerachse eine Torsion des Fadens f hervorgerufen, die für die verschiedenen Zeigerausschläge bestimmte, unveränderliche Werthe besitzt. Diese Art der Uebertragung ist also frei von den sonst auftretenden veränderlichen Gröfsen der Reibung, Gleitung oder Biegung und den dadurch bedingten Ungenauigkeiten der Zeigereinstellung. Diese Anordnung kann bei allen Mefsgeräthen Verwendung finden, bei denen es sich darum handelt, kleine, zu messende Verschiebungen in Drehbewegung umzusetzen.Because g is firmly connected to f , the rotation of the pointer axis causes a torsion of the thread f , which has certain unchangeable values for the various pointer deflections. This type of transmission is therefore free from the variable quantities of friction, sliding or bending that otherwise occur and the inaccuracies in the pointer setting caused by them. This arrangement can be used with all measuring devices that are used to convert small displacements to be measured into rotary motion. Patenτ-Anspruch:Patenτ claim: Reibungslose Zeigerübertragung von hoher Empfindlichkeit, gekennzeichnet durch einen zur Zeigerachse parallel gespannten und mit seinen Enden an dieser befestigten Faden, an dessen Mitte ein fest verbundenes Uebertragungsglied angreift, derart, dafs bei Drehung der Zeigerachse der Faden auf Torsion beansprucht wird.Smooth pointer transmission of high sensitivity, characterized by a stretched parallel to the pointer axis and with its ends attached to this thread the center of which engages a firmly connected transmission member, in such a way that upon rotation the pointer axis of the thread is subjected to torsion.
