  Vorrichtung zum genauen Einstellen von Zirkelschenkeln. 



   Um Zirkelschenkel genau einstellen zu können, wird bekanntlich quer zur Winkelöffnung eine Stellschraube angeordnet, die an einem Schenkel mit einem Zapfen, am andern Schenkel in einem Mutterstück gelagert ist, das behufs Lösung des Gewindeeingriffes bei beabsichtigten grösseren Ausschlägen unter Zusammendrückung einer Feder verschoben werden kann. Diese Einrichtung bedingt zur Ermöglichung der   Schraubenlagerung   eine besondere Ausgestaltung der Zirkelschenkel. In der Regel gehören aber zum Requisit eines Zeichners mehrere Zirkel verschiedener Grösse und auch zu verschiedenem Verwendungszweck, wie z. B. zum Messen oder zum Zeichnen. An mehreren oder allen Zirkeln derartige Einstellvorrichtungen vorzusehen, wäre aber nicht nur kostspielig, sondern auch unzweckmässig, weil sie für gewisse Arbeiten nur hinderlich wären. 



   Die Erfindung hat deshalb die Aufgabe gelöst, eine Zirkeleinstellvorrichtung zu schaffen, die, mit besonderen Befestigungselementen ausgerüstet, rasch und sicher an Zirkeln verschiedener Art und an beliebiger Schenkelstelle jeweilig vor Gebrauch festgeklemmt werden kann. 



   In der Zeichnung ist der Erfindungsgegenstand in beispielsweiser Ausführungsform dargestellt, u. zw. zeigt Fig. 1 den Zirkel in Seitenansicht, Fig. 2 im Schnitt. Die Vorrichtung kann an jedem beliebigen Zirkel angebracht werden, indem man die Klemmstücke a, b, deren Innenflächen parallelepipedisch oder konisch oder auch unter Benutzung einsetzbarer Futter in der Form ihrer Höhlung veränderbar ausgestaltet sein können, mittels der Druckschrauben c, d und der Klemmplatten e, f an irgendeinem Punkt der Zirkelschenkel festklemmt. Das Klemmstück   a   trägt an einem Drehzapfen das   Gabelstück g,   in dem das Ende der Stellschraube t drehbar gelagert ist. Am   Klemmstück   b ist die zweiteilige Mutter k,   l   mittels des als Drehzapfen ausgebildeten Ansatzes kl der einen Mutterhälfte k gelagert.

   Die Hälfte   l   der Mutter greift mit zwei Klauen in die andere Hälfte k ein. Ein an der Mutterhälfte   l   befestigter Stift m ist mit der 
 EMI1.1 
 dass die Mutter geschlossen gehalten wird. Ein Druck auf die Taste   H   öffnet die   Mutter/c, ,   so dass die Zirkelschenkel längs der Stellschraube frei bewegt werden können.

  Device for the precise adjustment of compass legs.



   In order to be able to adjust the compass legs precisely, an adjusting screw is arranged transversely to the angle opening, which is mounted on one leg with a pin and on the other leg in a nut piece, which can be moved by compressing a spring for the purpose of loosening the thread engagement with intended larger deflections. This device requires a special design of the compass legs to enable screw storage. As a rule, however, a draftsman's requirement includes several compasses of different sizes and also for different purposes, such as B. for measuring or drawing. Providing such adjustment devices on several or all of the circles would not only be costly but also impractical because they would only be a hindrance for certain work.



   The invention has therefore achieved the object of creating a compass setting device which, equipped with special fastening elements, can be quickly and securely clamped to compasses of various types and at any point on the leg before use.



   In the drawing, the subject matter of the invention is shown in an exemplary embodiment, u. Between Fig. 1 shows the compass in side view, Fig. 2 in section. The device can be attached to any compass by using the pressure screws c, d and the clamping plates e, the clamping pieces a, b, the inner surfaces of which can be designed to be parallelepipedic or conical or also changeable in the shape of their cavity using insertable chucks. f clamped at any point on the compass leg. The clamping piece a carries the fork piece g on a pivot pin in which the end of the adjusting screw t is rotatably mounted. The two-part nut k, l is mounted on the clamping piece b by means of the neck kl of one nut half k, which is designed as a pivot pin.

   Half l of the mother engages the other half k with two claws. A pin m attached to the nut half l is with the
 EMI1.1
 that the mother is kept closed. Pressing the H button opens the nut / c, so that the compass legs can be moved freely along the adjusting screw.
