  Vorrichtung zum Zeichnen ellipsenförmiger Kurven. 



   Die Erfindung bezieht sich auf jene bekannten Vorrichtungen zum Zeichnen ellipsenförmiger Kurven, bei denen der Schreibstift ausser einer kreisförmigen Bewegung gleichzeitig noch bei einer Umdrehung eine zweimalige hin und her gehende Bewegung macht. 



   Die Erfindung besteht in einer besonderen konstruktiven Ausführung dieser Vorrichtung. 



   Wie aus der Zeichnung   (Fig. l   und 2) ersichtlich ist, besteht. die Vorrichtung aus der ein fest aufgesetztes Zahnrad b tragenden Achse a, welche mittels zweier   Stahlspitzen   auf der Zeichenflächen fixiert wird, und aus einem zweiarmigen Rahmen e, j, g, welcher 
 EMI1.1 
 griff steht und den halben Durchmesser des Zahnrades b besitzt. die Kurbeln o verleihen mittels der   Kurbelstangen  ,   dem Querstabes eine geradlinige hin und her gehende Bewegung, welche durch Führung des Querstabes   ;   in den Schlitzen j gesichert wird. Der Querstab A trägt eine in der Höhe verschiebbare und mittels der Klemmschraube l einstellbare Hülse   it,   an der ein Horizontalstab i mit der Klemmhülse k für Bleistift   oder Reiss-   feder befestigt ist. 



   Durch Drehung des Rahmens rollt das   Zahnrad c auf dem festen Zahnrad   ab und 
 EMI1.2 
   gehende, geradlinige Bewegung mit   dem Querstabe h ausführt, zeichnet als Resultierende eine ellipsenförmige Kurve. 



   Durch das Verschieben   der Kurbelzapfen'in den Schlitzen   der Kurbelarme c mittles der Schrauben n verändert man die Exzentrizitäten der zu zeichnenden ellipsenförmigen Kurven. Wenn die   Kurbclzapfcn r in   die Verlängerung der Kurbelwelle d geschoben werden, zeichnet die Vorrichtung einen Kreis.

  Device for drawing elliptical curves.



   The invention relates to those known devices for drawing elliptical curves in which the pen, in addition to a circular movement, simultaneously makes two reciprocating movements during one revolution.



   The invention consists in a particular constructive embodiment of this device.



   As can be seen from the drawing (Fig. 1 and 2), there is. the device consists of the axis a, which carries a fixed gear wheel b and which is fixed on the drawing surface by means of two steel points, and a two-armed frame e, j, g, which
 EMI1.1
 handle is and half the diameter of the gear b has. the cranks o give by means of the connecting rods, the transverse rod a straight back and forth movement, which by guiding the transverse rod; is secured in the slots j. The transverse rod A carries a sleeve it which is vertically displaceable and adjustable by means of the clamping screw 1 and to which a horizontal rod i with the clamping sleeve k for pencil or drawing pen is attached.



   By rotating the frame, the gear c rolls on the fixed gear and
 EMI1.2
   executes walking, straight movement with the crossbar h, draws an elliptical curve as the resultant.



   By moving the crank pins in the slots of the crank arms c by means of the screws n, the eccentricities of the elliptical curves to be drawn are changed. When the crank journals r are pushed into the extension of the crankshaft d, the device draws a circle.
