  Gegenstand der vorliegenden Erfindung  ist ein Zeichenwinkel, der aus durchsichtigem  oder undurchsichtigem Material, beispiels  weise aus Zelluloid, Holz oder     dergl.    be  stehen kann und sich dadurch     auszeichnet,     dass er     mit        Ausnehmungen    versehen ist,  durch welche zu den     äussern    Anschlag  winkeln des Zeichenwinkels noch weitere  Winkel     anreissbar        sind.     



  In der Zeichnung ist der Erfindungs  gegenstand in zwei     beispielsweisen    Ausfüh  rungsformen dargestellt, und zwar zeigt:       Fig.    1 einen gleichschenkligen, rechtwink  ligen Zeichenwinkel mit zwei     Ausnehmungen     und       Fig.    2 einen     ungleichschenkligen,    recht  winkligen Zeichenwinkel     mit    zwei in der  Form anders gestalteten     Ausnehmungen.     



  Gemäss dem ersten     Ausführungsbeispiel       besitzt der     Zeichenwinkel    1 zwei     Ausneh-          mungen    2 und 3, durch die, ohne dass der  Zeichenwinkel 1 in seiner Lage verändert zu  werden braucht, verschiedene     Winkel        anreiss-          bar    sind.  



  Im zweiten Ausführungsbeispiel besitzt  der     Zeichenwinkel    1 zwei aus geradlinigen  Dreiecken bestehende     Ausnehmungen    2 und  3, durch die verschiedene Gegenwinkel an  reissbar sind. Es ist     selbstverständlich    mög  lich, dass die     Ausnehmungen    in dem Zeichen  winkel auch in andern, aus geraden Linien       bestehenden    Formen, als     wie    dargestellt, be  stehen können.  



  Durch diese     Ausnehmungen    wird ermög  licht, dass verschiedene Teilwinkel von zum  Beispiel 15 bis<B>90'</B> mit angeschlagenem       Zeichenwinkel        anreissbar    sind, was in bezug  auf ein rasches und exaktes Arbeiten als be  deutender Vorteil bewertet wird.



      Toe angle. Drawing angles, in the area of which figures such as old men, ellipses, hyperbolas, etc. are worked, are known, but not sol che with straight recesses with which different angles can be marked.



  The subject of the present invention is a drawing angle, which can be made of transparent or opaque material, for example celluloid, wood or the like. Be and is characterized in that it is provided with recesses through which the outer stop angles of the drawing angle even more Angles can be marked.



  In the drawing, the subject of the invention is shown approximately in two exemplary Ausfüh, namely shows: Fig. 1 an isosceles, right-angle drawing angle with two recesses and Fig. 2 is an unequal, right-angled drawing angle with two differently shaped recesses.



  According to the first exemplary embodiment, the drawing angle 1 has two recesses 2 and 3, through which different angles can be marked without having to change the position of the drawing angle 1.



  In the second embodiment, the drawing angle 1 has two recesses 2 and 3 consisting of straight triangles, through which different opposing angles can be torn. It is of course possible, please include that the recesses in the drawing angle in other, consisting of straight lines, shapes than as shown, be.



  These recesses make it possible to mark different partial angles from, for example, 15 to <B> 90 '</B> with an attached drawing angle, which is rated as a significant advantage with regard to quick and precise work.
