Der Schieferspitzer ist hergestellt aus einem Stahlblechstreifen a, welcher schleifenförmig, wie in Fig. ι und 4 ersichtlich, gebogen ist. Diese Schleife ist vom Bogen her konisch eingeschnitten. Durch diesen Einschnitt werden vier Blechkanten hergestellt, zwischen welchen der zu spitzende Schiefer b eingeschoben und mit etwas in seiner Längenrichtung geübtem Druck gedreht wird. Bei dieser Drehung schaben die vier am Schiefer anliegenden Kanten denselben in kurzer Zeit kegelförmig zu, mit anderen Worten, die schabenden Blechkanten spitzen den Schiefer.The slate sharpener is made from a sheet steel strip a, which is bent in the shape of a loop, as can be seen in FIGS. This loop is cut conically from the arch. Through this incision four sheet metal edges are produced, between which the slate b to be sharpened is inserted and rotated with a little pressure exerted in its longitudinal direction. During this rotation, the four edges that lie on the slate scrape it in a conical shape in a short time, in other words, the scraping sheet metal edges point the slate.
Bei dem in Fig. 4, 5 und 6 dargestellten ist das umschliefsende Kästchen an der dem Schlitz des Schieferspitzers zugekehrten Seite so durchlocht, dafs dieses Loch als Führung für den zu spitzenden Schiefer dient, zu dessen Schonung dieses Loch innerlich mit einem Gummipolster c versehen ist.In the in Fig. 4, 5 and 6, the umschliefsende box is on the side facing the slot of the slate sharpener side perforated so, that this hole acts as a guide for the to be sharpened slate, this hole is provided internally with a rubber cushion c to its sparing .
