KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. Die vorliegende Erfindung betrifft einen Bleistiftspitzer mit kegelförmiger geschlitzter Hülse, an welcher die Schneide tangential angeordnet ist. Es soll dadurch dem Uebelstande, dafs die Messerschneide nicht genau eingestellt werden kann, vorgebeugt werden. Zu diesem Zweck wird die Schneide des verstellbaren ■ Messerblattes durch zwei Anschläge genau in ihrer Lage gehalten, wobei sie eine Kante der kegelförmigen inneren Oeffnung der Hülse bildet. Bei dieser genauen Lage der Schneide wird ein Abbrechen der Bleistiftspitze verhütet. Ferner werden Messerblätter mit mehreren Schneiden benutzt, die nach einander eingestellt und abgenutzt werden.The present invention relates to a pencil sharpener with a conical slotted sleeve, at which the cutting edge is arranged tangentially. It is supposed to avoid the inconvenience that the knife edge cannot be precisely adjusted. To this Purpose is the cutting edge of the adjustable ■ knife blade with two stops exactly in held in their position, being an edge of the conical inner opening of the sleeve forms. This precise position of the cutting edge prevents the pencil tip from breaking off. Furthermore, knife blades with several cutting edges are used, which are set one after the other and get worn out. Fig. ι, 2 und 3 zeigen in Oberansicht, Schnitt und Seitenansicht einen derartigen Bleistiftspitzer, dessen Messerblatt drei. Schneiden hat. Fig. 4 zeigt einen Bleistiftspitzer, dessen Messerblatt sechs Schneiden hat.Fig. Ι, 2 and 3 show a top view, section and side view of such a pencil sharpener, its knife blade three. Has cutting. Fig. 4 shows a pencil sharpener, its Knife blade has six cutting edges. Bei der in Fig. 1 bis 3 dargestellten Ausführungsart ist die kegelförmige Hülse c mit der tangentialen Platte b verbunden, worauf das dreieckige, mit drei Schneiden versehene Messerblatt befestigt ist. Hierzu dient eine Schraube f; indem diese in der Platte b durch einen Schlitz b1 führt, der senkrecht zur Hülse c liegt, läfst sich das Messerblatt in der Richtung nach der Hülse zu verstellen. Damit die dem eingeführten Bleistift dargebotene Schneide genau in der Richtung des Schlitzes der Hülse c liegt, sind an dieser zwei Anschläge c1 und c2 vorhanden, an denen die Enden der Schneide Stützung finden. Soll eine der drei Schneiden a1 a2 as benutzt werden, so braucht man sie nur gegen die Anschläge c1 c2 zu legen und dann die Messerplatte α festzuschrauben. Der Griff d läfst sich an der Hülse c an beliebiger Stelle befestigen und beliebig ausführen.In the embodiment shown in FIGS. 1 to 3, the conical sleeve c is connected to the tangential plate b , whereupon the triangular knife blade provided with three cutting edges is attached. A screw f is used for this; in that this leads in the plate b through a slot b 1 which is perpendicular to the sleeve c , the knife blade can be adjusted in the direction towards the sleeve. So that the cutting edge presented to the inserted pencil lies exactly in the direction of the slot in the sleeve c , there are two stops c 1 and c 2 on this, on which the ends of the cutting edge find support. If one of the three cutting edges a 1 a 2 a s is to be used, it only needs to be placed against the stops c 1 c 2 and then screwed down the cutter plate α . The handle d can be attached to the sleeve c at any point and carried out in any way. Die in Fig. 4 dargestellte Ausführung unterscheidet sich von der vorher beschriebenen durch die Anwendung eines Messerblattes a mit sechs Schneiden a1 bis α6. Das Messerblatt kann auch jede andere vieleckige Gestalt, mit entsprechend vielen Schneiden haben.The embodiment shown in FIG. 4 differs from the one previously described in that it uses a knife blade a with six cutting edges a 1 to α 6 . The knife blade can also have any other polygonal shape with a corresponding number of cutting edges.
