Die Erfindung betrifft einen Bleistift, dessen Mine mittels eines feststellbaren Schlittens verschoben wird. Die bekannten Klemmvorrichtungen besitzen den Übelstand, daß sie ein Zurückgehen der Mine beim Gebrauch des Bleistiftes nicht unter allen Umständen wirksam verhindern. Dieser Ubelstand wird nach der Erfindung dadurch beseitigt, daß die Sperrung des Schlittens durch einen Hebel herbeigeführt wird, der an seinen Flachseiten mit konzentrisch zu seinem Drehpunkt angeordneten, schneidenartigen Rippen versehen ist.The invention relates to a pencil, the lead of which is moved by means of a lockable slide will. The known clamping devices have the disadvantage that they are a retreat of the mine when using the Do not prevent the pencil effectively under all circumstances. This evil will be after the invention eliminated in that the locking of the slide is brought about by a lever which is arranged on its flat sides with concentric to its pivot point, cutting-like ribs is provided.
Auf der Zeichnung ist der Erfindungsgegenstand dargestellt, und zwar zeigt:
Fig. ι den Bleistift teilweise im Schnitt,The subject of the invention is shown in the drawing, namely:
Fig. Ι the pencil partially in section,
Fig. 2 den Schlitten der Mine undFig. 2 the slide of the mine and
Fig. 3 den Klemmhebel in größerem Maßstabe. 3 shows the clamping lever on a larger scale.
Die Klemmvorrichtung besteht aus dem Schlitten α und dem Feststellhebel f. Der Schlitten α, der die Mine δ aufnimmt, ist mit seinem rückwärtigen Ende e mit dem Hebel f gelenkig verbunden. Dieser Hebel ist in einer mit der Bohrung c des Bleistiftes d in Verbindung stehenden Nut g geführt und an seinen Flachseiten mit konzentrisch zu seinem Drehpunkte i angeordneten, schneidenartigen Rippen h versehen, durch welche die Sperrung des Schlittens herbeigeführt wird. Die Bohrung c ist durch einen Pfropfen k geschlossen.The clamping device consists of the slide α and the locking lever f . The slide α, which receives the mine δ, is articulated with its rear end e to the lever f. This lever is guided in a groove g connected to the bore c of the pencil d and provided on its flat sides with blade-like ribs h arranged concentrically to its pivot point i , through which the locking of the slide is brought about.
