Description

  

  Kreidespitzer.    Gegenstand der vorliegenden Erfindung  ist ein zum Beispiel zum Spitzen einer Schnei  derkreide sich eignender Kreidespitzer, der  sich dadurch kennzeichnet, dass im Deckel  einer beim Spitzen der Kreide den dabei er  zeugten Kreidestaub aufnehmenden Schachtel  zwei im Winkel zueinander angeordnete,  einen unten offenen Schlitz bildende Feilen  stücke vorgesehen sind, zwischen welchen  die Kreide mit ihrem zu spitzenden Teil ver  schoben wird.  



  Auf der beiliegenden Zeichnung ist ein  Ausführungsbeispiel des Erfindungsgegen  standes dargestellt.  



       Fig.1    ist eine perspektivische Ansicht  des Kreidespitzers;       Fig.    2 ist ein Querschnitt durch den  selben, und       Fig.    3 zeigt eine Einzelheit desselben.  A ist eine Holzschachtel mit Schiebe  deckel     a,    in welchem zwei im Winkel zu  einander angeordnete, einen unten offenen  Schlitz bildende     Feilenstücke    b befestigt sind,  von denen eines in     Fig.    3     herausgezeichnet       ist.

   Diese beiden     Feilenstücke    b sind auf den  einander zugekehrten Seiten derselben mit  verhältnismässig groben     Scbärfzähnen    ver  sehen, die sich schräg über die ganze Breite  der     Feilenstücke    erstrecken und alle nach  der gleichen Seite hin gerichtet sind.  



  Zum Spitzen zum Beispiel -einer Schnei  derkreide wird dieselbe mit ihrer zu spitzen  den Kante zwischen die beiden     Feilenstücke    b  eingeführt und einigemal gegen die Zähne  dieser letzteren zu verschoben. Der dabei  erzeugte Kreidestaub sammelt sich, wie in       Fig.2    angedeutet ist, auf dem Boden der  Schachtel     f1    an.



  Chalk sharpener. The subject of the present invention is a chalk sharpener suitable, for example, for sharpening a tailor's chalk, which is characterized in that in the lid of a box that absorbs the chalk dust when sharpening the chalk, two files arranged at an angle to each other, forming a slot open at the bottom are provided, between which the chalk is pushed ver with its sharpened part.



  On the accompanying drawing, an embodiment of the subject invention is shown.



       Figure 1 is a perspective view of the pencil sharpener; Fig. 2 is a cross section through the same, and Fig. 3 shows a detail of the same. A is a wooden box with a sliding lid a, in which two pieces of files b, which are arranged at an angle to each other and form a slot open at the bottom, are attached, one of which is shown in FIG.

   These two file pieces b are seen ver on the facing sides of the same with relatively coarse scarfing teeth, which extend obliquely over the entire width of the file pieces and are all directed towards the same side.



  To point, for example, a tailor's chalk, the same is inserted with its to point the edge between the two file pieces b and shifted a few times against the teeth of the latter. The chalk dust generated in the process collects, as indicated in FIG. 2, on the bottom of the box f1.
