Bleistiftspitzmaschiue.
Die Erfindung betrifft eine Bleistiftspitzmaschine, bei der eine biegsame Rasierklinge bekannter Art als Fräser zur Verwendung gelangt.
In der Zeichnung ist ein Ausführungsbeispiel des. Erfindungsgegenstandes in Fig. 1 in teilweise geschnittener Ansicht dargestellt, während die Fig. 2 und 3, letztere in grösserem Massstabe, Einzelheiten veranschaulichen.
Bei der sonst in bekannter Weise ausgeführten Maschine werden durch Umdrehung der Kurbel 1 einerseits die Welle 2 zum Aufstecken des Fräsers, anderseits durch Zahnradübersetzung die Einführungs- hülse. J zum Einschieben des zu spitzenden Bleistiftes in Drehung versetzt. Der Erfindung gemäss ist auf der Welle 2 zum Einspannen der Rasierklinge 4 eine Einspannvorrichtung mit zwei Backen 5 und 6 aufgeschoben, von denen der erstere. 5 mit seiner konkaven Fläche der entsprechend konvexen Fläche des Backens 6 angepasst ist. Die Einspannvorrichtung ist derart angeordnet, dass beide Schneiden der Klinge 4 in derselben Drehebene umlaufen.
Zum Kuppeln des Bleistiftes mit der rotierenden Einführungshülse 3 ist an dieser eine Kapsel 7

Pencil sharpener.
The invention relates to a pencil sharpener in which a flexible razor blade of a known type is used as a milling cutter.
In the drawing, an exemplary embodiment of the subject matter of the invention is shown in FIG. 1 in a partially sectioned view, while FIGS. 2 and 3, the latter on a larger scale, illustrate details.
In the machine, which is otherwise designed in a known manner, the shaft 2 for attaching the milling cutter is turned on the one hand by rotation of the crank 1, and on the other hand the insertion sleeve is activated by gear transmission. J rotated to insert the pencil to be sharpened. According to the invention, a clamping device with two jaws 5 and 6 is pushed onto the shaft 2 for clamping the razor blade 4, of which the former. 5 is adapted with its concave surface of the corresponding convex surface of the jaw 6. The clamping device is arranged such that both cutting edges of the blade 4 rotate in the same plane of rotation.
A capsule 7 is attached to the rotating insertion sleeve 3 for coupling the pencil to the rotating insertion sleeve 3
EMI1.1
PATENT CLAIMS:
1. Pencil sharpening machine, characterized in that the rotating knife clamping device has two jaws (5, 6) with concave and convex surfaces, between which a flexible razor blade known old can be clamped as a milling cutter.
