Description

Spitzer für Blei- oder Füllstifte mit Schraubantrieb sind bereits bekannt. Das Wesen der im folgenden beschriebenen Erfindung beruht nun darin, daß an Stelle des Messerkopfes ein mittels einer biegsamen Welle gegen Drehen um die eigene Achse gesicherter Fräser tritt, welcher durch eine der Kegelform der Minenspitze entsprechend abgebogene Welle in eine kreisende Bewegung versetzt wird.Sharpeners for lead or fountain pens with screw drive are already included known. The essence of the invention described below is based on the fact that in place of the cutter head by means of a flexible shaft against rotation around the own axis secured cutter occurs, which through one of the conical shape of the mine tip correspondingly bent shaft is set in a circular motion.

Der Spitzer besteht aus dem Gehäuse i mit Abschlußkappe 2 und daran befestigter Schraubwelle 3 sowie aus der in Gehäuse i verschiebbar angeordneten und durch Druckfeder .. über Schubrohr 5 in der Ausgangsstellung gehaltenen Schubhülse 6, welche an ihrem oberen Ende die Aufnahmebüchse 7 für den Füllstift trägt. Der in Schubhülse 6 zum Ausgleich differenter Minenlängen verschiebbar angeordnete Spitzmechanismus, welcher seinerseits gegenüber der Schubhülse 6 durch Druckfeder 8 in der Ausgangsstellung gehalten wird, besteht aus der die Drehbewegung von der Schraubenführung 9 auf die Kurbelwelle io übertragenden Hohlwelle i i und dem durch das abgewinkelte Ende der Kurbelwelle io kreisend bewegten Fräser 12 mit Anschlaghülse 13, welcher seinerseits über Lagerschild 14 mittels einer biegsamen Welle 15 gegen Drehbewegungen. gesichert ist. Durch Anordnung eines AYialkugellagers 16 wird die bei der Umwandlung der Schub- in Drehbewegung entstehende Reibung auf ein Minimum reduziert.The sharpener consists of the housing i with the end cap 2 and on it attached screw shaft 3 as well as from the slidably arranged in housing i and by means of a compression spring .. via the push tube 5, the push sleeve held in the initial position 6, which carries the receptacle 7 for the filler pen at its upper end. Of the Sharpening mechanism arranged displaceably in push sleeve 6 to compensate for different lead lengths, which in turn opposite the thrust sleeve 6 by compression spring 8 in the starting position is held, consists of the rotary movement of the screw guide 9 on the Crankshaft io transmitting hollow shaft i i and through the angled end of the Crankshaft io circularly moving cutter 12 with stop sleeve 13, which in turn via end shield 14 by means of a flexible shaft 15 against rotational movements. secured is. By arranging an AYialkugellager 16, the when converting the thrust Friction arising in rotary motion is reduced to a minimum.

Die Arbeitsweise ergibt sich wie folgt: Nach Einführen des Füllstifts in die Aufnahmebüchse 7 wird der in der Schubhülse 6 längs verschiebbare Spitzmechanismus io-i5 so weit zurückgedrängt, bis das vordere Ende des Füllstifts in der Aufnahmebüchse 7 zur Anlage kommt. Bei weiterer Einwärtsbewegung wird auch die Schubhülse 6 mit Schubrohr 5 mitgenommen, womit der Schraubantrieb in Tätigkeit tritt, dessen Drehbewegung dem Fräser 12 über Hohlwelle i i und Kurbelwelle io eine kreisende Bewegung erteilt. Die Rückführung nach beendeter Schubbewegung erfolgt durch Druckfeder 4. Zum Entleeren wird die Aufnahmebüchse 7 abgenommen.The way of working is as follows: After inserting the filler pen The sharpening mechanism, which is longitudinally displaceable in the push sleeve 6, is inserted into the receiving sleeve 7 io-i5 pushed back until the front end of the filler pen is in the receptacle 7 comes to the plant. With further inward movement, the thrust sleeve 6 also becomes Thrust tube 5 taken along, with which the screw drive comes into action, its rotary movement the milling cutter 12 is given a circular motion via the hollow shaft i i and the crankshaft io. The return after the end of the pushing movement is carried out by compression spring 4. For emptying the receiving sleeve 7 is removed.
