Der Schieferstiftspitzer besteht aus einem hohlen, runden Metallgefäfs, dessen oberer Theil konisch zuläuft.The slate pencil sharpener consists of a hollow, round metal vessel, the upper part of which tapers conically.
Das Innere des Gefäfses ist nach Fig. 2 mit Gyps ausgefüllt. -■ In diese Gypsmasse werden Glasplatten schräg eingesteckt, und zwar derart, wie es die Figuren darstellen.The interior of the vessel is filled with Gyps according to FIG. 2. - ■ Glass plates are inserted at an angle into this gypsum mass, as shown in the figures.
In die obere Oeffnung wird nun, wie Fig. 1 und 2 andeuten, der Schieferstift hineingesteckt und der Schärfer herumgedreht; es greifen dadurch die scharfen Kanten der Glasstückchen den Stift an und wird er dadurch geschärft, bis er zuletzt in die Spitze ausläuft, wie aus Fig. 1 ersichtlich.As shown in FIGS. 1 and 2, the slate pin is now inserted into the upper opening and the sharpener turned around; this grips the sharp edges of the pieces of glass the pencil on and it is thereby sharpened until it finally runs out into the tip, as shown in Fig. 1 evident.
