KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die vorliegende Erfindung betrifft Registrierinstrumente mit einem an einem Zeiger befestigten Schreibgefäß. Es soll die Aufgabe gelöst werden, daß bei plötzlichen Ausschlägen des Zeigers, die z. B. bei plötzlichen Änderungen zu registrierender Ströme entstehen, die Kraft vermehrt wird, mit welcher das Schreibröhrchen bzw. die Schreibfeder auf dem Registrierpapier aufliegt, so daß durchThe present invention relates to recording instruments having one attached to a pointer Writing vessel. The object is to be achieved that in the event of sudden fluctuations of the pointer, the z. B. arise in the event of sudden changes in the currents to be registered, the force with which the pen or pen opens is increased rests on the recording paper so that through
ίο die größere Reibung einerseits eine sichere Registrierung, andererseits eine bessere Dämpfung der Zeigerausschläge hervorgerufen wird. Die Lösung der Aufgabe besteht darin, daß das Schreibgefäß so aufgehängt wird, daß sein Schwerpunkt sich zwischen der Bewegungsebene der Drehachse des Schreibgefäßes und dem Papier befindet. Infolgedessen wird die Zentrifugalkraft, welche bei plötzlichen Ausschlägen auftritt, das Gefäß nach dem Papier zu kippen bestrebt sein, mithin den Auflagedruck des Rohres vergrößern.ίο the greater friction on the one hand a safe one Registration, on the other hand, a better damping of the pointer deflections is caused. The solution to the problem is that the writing vessel is hung so that its center of gravity is between the plane of movement of the axis of rotation of the writing vessel and the paper. As a result, the centrifugal force, which at sudden If rashes occur, strive to tilt the vessel towards the paper, hence the Increase the contact pressure of the pipe.
In der schematischen Skizze bedeutet A die Drehachse des Instrumentes, Z den Zeiger, der sich um diese Achse bewegt, ζ den Zapfen, mit welchem das Gefäß G an dem Zeiger aufgehängt ist. Der Schwerpunkt S des Zeigers befindet sich, wie man sieht, unterhalb des Zapfens, ebenso wie das Registrierpapier P. Es ist ersichtlich, daß auf den Schwerpunkt S des Gefäßes eine Zentrifugalkraft in Richtung des Pfeiles X wirkt, von welcher ein Teil durch die Zapfenlagerung ζ aufgenommen wird, während ein anderer Teil zur Drehung des Gefäßes G um den Zapfen dient, und mithin das Röhrchen R das Schreibgefäß gegen das Papier P drückt. Dieser Druck wird um so stärker, je schnellere Bewegungen der sich drehende Zeiger ausführt.In the schematic diagram, A means the axis of rotation of the instrument, Z the pointer that moves around this axis, ζ the pin with which the vessel G is suspended from the pointer. The center of gravity S of the pointer is, as you can see, below the pin, as is the recording paper P. It can be seen that a centrifugal force acts on the center of gravity S of the vessel in the direction of arrow X , part of which is caused by the pin bearing ζ is picked up, while another part is used to rotate the vessel G around the pin, and consequently the tube R presses the writing vessel against the paper P. This pressure increases the faster the rotating pointer moves.
