  Verfahren zur Herstellung von   Schrelb8tiftspitzern.   



   Den Gegenstand der Erfindung bildet ein Verfahren zur Herstellung von Schreibstiftspitzern. Das Verfahren besteht darin, dass ans Stahlblech oder   Bandstahl Formstücke F   nach Fig. 1 oder Fig. 2 der Zeichnung mit gabelförmigen Enden e geschnitten werden. 
 EMI1.1 
 des Formstückes aufeinander und die abgebogenen Gabeln e nebeneinander zu liegen kommen, wie es die Fig. 4 veranschaulicht, so dass die vier Gabelschenkel i eine Pyramide und ihr Verbindungsstück einen Stiel s bilden. 



   Die inneren Ränder r der Schenkel i (Fig. 5) haben die Aufgabe der Schneiden und beim Einstecken des Schreibstiftes und Drehen des letzteren oder des Werkzeuges bearbeiten die Schneiden das Ende des Schreibstiftes in die Form eines   Segel.   



   Der Schreibstiftspitzer kann mit seinem Stiel s in einen geeigneten Griff oder dgl. eingesetzt werden. 



   Die zweite Ausführung des Verfahrens zur Herstellung von Schreibstiftspitzern besteht darin, dass aus Halbrundeisen oder Stahl hergestellte Stäbchen an ihren beiden Enden gespalten und in die Form einer Gabel gebracht werden. Nach dem Abbiegen der Gabeln in die in Fig. 3 gestrichelte Lage wird das Stäbchen in der Mitte in bereits beschriebener Art, wie die Fig. 4 zeigt, umgebogen. 



   Der Querschnitt des Stieles s ist bei Anwendung des   Halbrundstahls   kreisförmig, während der Querschnitt bei Anwendung der Formstücke aus Blech oder Bandstahl quadratisch oder rechteckig ist   (Fig. fi)   
PATENT-ANSPRÜCHE :
1. Verfahren zur Herstellung von Schreibstiftspitzern, dadurch gekennzeichnet, dass aus Blech oder Bandstahl Formstücke (F) mit gabelförmigen Enden (e) geschnitten werden, wonach die lett. eren abgebogen und die Formstücke in der Mitte umgebogen werden, damit die Gabeln   (e)   nebeneinander zu liegen kommen.

  Process for the production of pencil sharpeners.



   The subject matter of the invention is a method for producing pen sharpeners. The method consists in that molded pieces F according to FIG. 1 or FIG. 2 of the drawing with forked ends e are cut on the steel sheet or strip steel.
 EMI1.1
 of the shaped piece on top of one another and the bent forks e come to lie next to one another, as illustrated in FIG. 4, so that the four fork legs i form a pyramid and their connecting piece forms a stem s.



   The inner edges r of the legs i (Fig. 5) have the task of cutting and when inserting the pen and turning the latter or the tool, the cutting edges process the end of the pen in the shape of a sail.



   The pencil sharpener can be used with its handle s in a suitable grip or the like.



   The second embodiment of the process for the production of pen sharpeners consists in splitting sticks made of half-round iron or steel at both ends and making them into the shape of a fork. After the forks have been bent into the position shown by dashed lines in FIG. 3, the small rod is bent in the middle in the manner already described, as shown in FIG. 4.



   The cross-section of the stem s is circular when using the half-round steel, while the cross-section when using the shaped pieces made of sheet metal or strip steel is square or rectangular (Fig. Fi)
PATENT CLAIMS:
1. A process for the production of pencil sharpeners, characterized in that shaped pieces (F) with fork-shaped ends (e) are cut from sheet metal or strip steel, after which the lettuces are bent and the shaped pieces are bent in the middle so that the forks (e) come to lie next to each other.
