  Ellipsenzirekl. 



   Das der Erfindung zugrunde liegende Prinzip ist in Fig. 1 dargestellt. Zwei Scheiben A1 und   A,   sind an der Stange S drehbar befestigt und durch einen Faden, Riemen oder dgl. miteinander verbunden. Hält man die Scheibe A2 fest und dreht die 
 EMI1.1 
 Bewegung. Die Scheibe Al dreht sich erstens um den Mittelpunkt der Scheibe   A4 zweiten   um ihre eigene Achse. Ein jeder Punkt, der mit der Scheibe A1 fest verbunden ist, beschreibt eine Ellipse, wenn man den Radius   on A2 doppelt   so gross annimmt als den der Scheibe.   111 was   man leicht nachweisen kann. 



   Der Zirkel besteht, wie aus Fig. 2 und 3 ersichtlich, aus zwei   Zahnrädchen z1 und @2,   welche durch eine Zahnstange Z verbunden sind. Das grössere Zahnrad      ist auf einer   Hülse lt   befestigt, welche mit Spitzen r versehen ist, mittels der die Hülse h auf der Zeichenfläche festgesteckt wird. 



   In dieser Hülse ist drehbar eine Spindel p gelagert, die oben mit einem Gehäuse g und einer Fixierschraube i versehen ist. In diesem Gehäuse ist eine Stange S verschiebbar, welche man durch die Schraube fixieren kann. Am Ende der Stange   8   ist das andere Zahnrad z1 befestigt. Mit diesem Zahnrad ist ein Arm R fest verbunden, welcher einen   Ble ; stift   oder Feder tragt. Dadurch, dass sich die Länge der Stange S und die des Armes   R   (Fig. 2) ändern kann, können mit Hilfe dieses Apparates alle möglichen Arten und Grössen von Eilipsen gezeichnet werden. Beide Zahnradchen sitzen zwischen zwei grösseren Scheiben, damit die Zahnstange sicher geführt ist.

  Elliptical



   The principle on which the invention is based is shown in FIG. Two disks A1 and A are rotatably attached to the rod S and connected to one another by a thread, belt or the like. If you hold the disc A2 and turn it
 EMI1.1
 Move. The disk A1 rotates first around the center of the disk A4, second around its own axis. Every point that is firmly connected to the disk A1 describes an ellipse, assuming the radius on A2 is twice as large as that of the disk. 111 which one can easily prove.



   As can be seen from FIGS. 2 and 3, the compass consists of two toothed wheels z1 and @ 2, which are connected by a toothed rack Z. The larger gear is attached to a sleeve lt, which is provided with tips r, by means of which the sleeve h is pinned on the drawing surface.



   A spindle p is rotatably mounted in this sleeve and is provided at the top with a housing g and a fixing screw i. A rod S can be moved in this housing and can be fixed with the screw. At the end of the rod 8, the other gear z1 is attached. With this gear, an arm R is firmly connected, which a Ble; pen or pen. Because the length of the rod S and that of the arm R (Fig. 2) can change, all possible types and sizes of ellipses can be drawn with the help of this apparatus. Both gears sit between two larger disks so that the rack is safely guided.
