KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Erfindung betrifft einen Zirkel mit zwangläufiger Führung, bei dem die Kopfenden der Schenkel mittels Zahnsegmente ineinandergreifen und einseitig an einem Kopfstück mittels Schrauben drehbar befestigt sind. Das Neue an der Erfindung ist, daß diese Befestigungsschrauben durch einen Doppelkonus (Achterstück) gegeneinander abgestützt sind und dadurch den letzteren federnd ίο gegen die Kopfenden der Schenkel drücken.The invention relates to a compass with positive guidance in which the head ends the legs interlock by means of toothed segments and on one side on a head piece are rotatably attached by means of screws. The novelty of the invention is that these fastening screws have a double cone (Figure eight) are supported against each other and thereby press the latter resiliently ίο against the head ends of the legs.
Auf der Zeichnung ist der Erfindungsgegenstand dargestellt, und zwar zeigtThe subject of the invention is shown in the drawing, namely shows
Fig. ι den Zirkel von vorn gesehen,Fig. Ι seen the circle from the front,
Fig. 2 denselben von der Seite gesehen,
Fig. 3 einen Schnitt nach der Linie A-B der Fig. 1,Fig. 2 the same seen from the side,
Fig. 3 is a section along the line AB of Fig. 1,
Fig. 4 eine Einzelheit des Zirkels.4 shows a detail of the circle.
An einem starr mit dem Bügel verbundenen Kopfhaltestück 1 werden die mit Zähnen versehenen Kopfenden der Schenkel 2 einseitig mittels Schrauben 3, die durch einen Lagerdoppelkonus 4 gegeneinander abgestützt sind, drehbar gehalten.On a head support piece 1 rigidly connected to the bracket, those with teeth provided head ends of the legs 2 on one side by means of screws 3, which by a Bearing double cone 4 are supported against each other, held rotatably.
Das Kopfhaltestück 1 ist herzförmig ausgebildet und mit zwei halbkreisförmigen Aussparungen oder Einbuchtungen versehen, um die Kopfenden der Schenkel zu führen. Die Schenkel drehen sich um die gewissermaßen als Achsen dienenden Schrauben 3, die mit ihrem einen Ende in dem Kopfhaltestück 1, mit dem anderen Ende dagegen in dem Doppelkonus 4 gelagert sind, so daß sie, wie in einer Kulisse liegend, stets gleichen Abstand zueinander haben.The head support piece 1 is heart-shaped and has two semicircular recesses or indentations are provided to guide the head ends of the legs. The legs rotate around them, so to speak screws 3 serving as axes, one end of which is in the head support piece 1, with the other end, however, are mounted in the double cone 4, so that they, like lying in a backdrop, always have the same distance from one another.
Durch diese Anordnung ist es ermöglicht worden, mittels Anziehens der Schrauben die Bewegung jedes Schenkels für sich zu regulieren, so daß durch die infolge der Verzahnung hervorgerufene zwangläufige Führung ein durchaus gleichmäßiger Gang bzw. eine solche Bewegung der beiden Schenkel gegeneinander gewährleistet und somit ein toter Gang vermieden wird.By this arrangement it has been made possible by tightening the screws To regulate movement of each leg for itself, so that by the result of the toothing evoked inevitable guidance a perfectly even gait or such a movement of the two legs against each other guaranteed and thus a dead gear is avoided.
Natürlich kann die Befestigung der Schenkel auf dem Verbindungsstück auch in anderer Weise als wie beschrieben erfolgen, ohne den Rahmen der Erfindung zu verlassen. Ebenso kann auch das Kopfstück jede andere geeignete Form haben.Of course, the attachment of the legs on the connector can also be done in another way Manner as described, without departing from the scope of the invention. as well the head piece can also have any other suitable shape.
