  Vorrichtung zur graphischen Drittelung von Winkeln und zur graphischen Ermittlung der Quadrat- und Kubikwurzel. 



   Die Erfindung betrifft eine Vorrichtung zur graphischen Drittelung von Winkeln und zur graphischen Ermittlung der Quadrat-und Kubikwurzel. Die Vorrichtung lässt bei ihrer Benutzung einen Zusammenhang der genannten Probleme erkennen. 



   Eine beispielsweise Ausführungsform der Vorrichtung gemäss der Erfindung ist in der Zeichnung in Draufsicht dargestellt, wobei Fig. 1 die Grundstellung, Fig. 2 eine   Messstellung   und Fig. 3 schematisch

 ablesbar Strecke   A   ist dann die Kubikwurzel aus der gegebenen Zahl.   Ähnlich   wird die Quadratwurzel einer Zahl ermittelt. Die gegebene Zahl wird jedoch auf dem Lineale b eingestellt, wobei sich die Strecke A als Quadratwurzel von B ergibt. Umgekehrt ergibt nach Einstellung einer gegebenen Zahl als Strecke A die Strecke B das Quadrat derselben und die Strecke A'die halbe dritte Potenz. 



  Bei einer gegebenen Winkelstellung der beiden Lineale a, b ergibt sich der dreifache Winkel zwischen dem Lenker d und dem Lineale a mit dem Scheitel   a".   



   Bei feinmechanischer Ausführung der Vorrichtung kann am rechten Ende des Lineals b ein bewegliches Kugelgelenk angebracht sein, das, in einer Längsnut des Lineals a gleitend, das rechte Ende des Lineals b zwangweise in ständiger Anlehnung an die Kante des Lineals a (Winkelstellung) erhält.

  Device for the graphical division of angles into thirds and for the graphical determination of the square and cube roots.



   The invention relates to a device for graphically dividing angles into thirds and for graphically determining the square and cube roots. When used, the device reveals a connection between the problems mentioned.



   An example embodiment of the device according to the invention is shown in the drawing in a top view, with FIG. 1 showing the basic position, FIG. 2 a measuring position and FIG. 3 schematically

 legible segment A is then the cube root of the given number. Similarly, the square root of a number is found. However, the given number is set on the ruler b, with the distance A being the square root of B. Conversely, after setting a given number as segment A, segment B results in its square and segment A 'results in half the third power.



  At a given angular position of the two rulers a, b there is three times the angle between the link d and the ruler a with the vertex a ".



   In the case of a fine mechanical design of the device, a movable ball joint can be attached to the right end of the ruler b, which, sliding in a longitudinal groove of the ruler a, receives the right end of the ruler b in constant reference to the edge of the ruler a (angular position).



   PATENT CLAIMS:
1. A device for graphically dividing angles into thirds and for graphically determining the square and cube roots, characterized in that two rulers (a, b) provided with graduations are pivotably mounted on a support surface around a fixed axis a ", bo) and are supported by a are connected to the pivot point (a0) of one ruler (a) and to a slide (c) acting on the other ruler (b), one end of the first ruler (b), the pivot points ", al) and the points m, n) of the slider (e) each determine a broken line whose breakpoints lie in the edges of the rulers and whose branches are equal to the unit.
