Der Zapfen d besitzt ein Vierkant, welcher auf die Hülse b steckt, deren Ansatzfläche auf dem Schenkel e schleift. Die Mutter α drückt auf die Hülse b, wodurch der Zirkelgang geregelt wird. Die kleinste Drehung der Mutter α wird den Zirkelgang verändern, und durch ein festes Anziehen derselben mit den Fingern kann man den Zirkel vollständig feststellen.The arrangement of the same is as follows: In the leg f , the steel ring c is embedded, which moves in the screwed-in groove of the leg e . The pin d has a square, which is placed on the sleeve b , the attachment surface grinds on the leg e. The nut α presses on the sleeve b, whereby the circular gear is regulated.
