Description

Die Erfindung betrifft einen Griffelspitzer, der von Hand zu betätigen ist. Die bekannten Spitzer dieser Art haben nur eine Schneide, die deshalb, und weil sie verhältnismäßig offen liegt, raschem Verschleiß unterworfen ist. Überdies ist die Führung des Griffels bei diesen bekannten Spitzern schlecht. Die mit einer Einspannvorrichtung für den Griffel versehenen Griffelspitzmaschinen, die mit mehreren Schneiden ausgerüstet sind, vermeiden zwar obige Fehler, sind aber teuer.The invention relates to a pencil sharpener that can be operated by hand is. The known sharpeners of this type have only one cutting edge, which is why, and because it is relatively open and is subject to rapid wear and tear. Besides the handling of the stylus is poor in these known sharpeners. The one with a Clamping device for the stylus provided stylus sharpening machines with several Cutting edges avoid the above errors, but they are expensive.

Für den Griffelspitzer gemäß der Erfindung ist darum eine Vielzahl von spanabhebenden Schneiden vorgesehen, die auf einem Kegelmantel angeordnet sind. Der Griffel ist während der Spanabhebung in der Öffnung eines als Hebel ausgebildeten Teiles geführt, der um einen in der Kegelachse festen Dorn drehbar ist.For the pencil sharpener according to the invention there is therefore a multitude provided by cutting edges, which are arranged on a conical surface. During the chip removal, the stylus is in the opening of a lever designed as a lever Part out, which is rotatable about a fixed mandrel in the cone axis.

Die beiden Figuren veranschaulichen den Gegenstand der Erfindung, und zwar die Fig. i im Querschnitt, die Fig. 2 in der Draufsicht. In der Dose i aus hartem Metall sind an der kegelförmigen Innenwand die Schneiden 2 eingeschliffen und in Bodennähe ein schneidenfreier Raum ausgespart. In Mitte der Dose i ist der Dorn 3 eingenietet, auf welchem der Hebel 4 drehbar angeordnet und durch die Scheibe 5 und die Schraube 6 gegen axiale Verschiebung gesichert ist. An seinem drehachseniernen Ende hat der Hebel 4 eine kegelmantelförmige Öffnung 7, in welcher der Griffel 8 so geführt und vorgeschoben und gedreht wird, dalß die Schneiden 2, während der Hebel 4 mit dem Griffel um die Hebelachse gedreht wird, die Späne abheben können.The two figures illustrate the subject matter of the invention, namely Fig. i in cross section, Fig. 2 in plan view. In the can i made of hard metal, the cutting edges 2 are ground into the conical inner wall and a cut-free space is cut out near the floor. In the middle of the can i is the Riveted mandrel 3 on which the lever 4 is rotatably arranged and through the disc 5 and the screw 6 is secured against axial displacement. On his rotary axis iron At the end of the lever 4 has a cone-shaped opening 7 in which the stylus 8 so guided and advanced and rotated that the cutting edge 2, during the Lever 4 is rotated with the stylus around the lever axis, the chips can be lifted off.
