  Vorrichtung zum Reinigen von Wandtafeln. 



   Vor) iegende Erfindung hat den Zweck, die Befeuchtung der   Schreibfächen   einer Wandtafel selbsttätig zu bewirken. 



   In der Zeichnung zeigt Fig. 1 die Gesamtansicht der Wandtafel, Fig. 2 den Schnitt durch Hahn b und Fig. 3 den Schnitt durch die Rohre d und e. 



   Der Erfindungsgedanke liegt in der Anordnung eines   Wasserbehälters a, ans dem   das Wasser in die Rohre d und e fliesst, die dasselbe wiederum auf   die Schreibfläcben   der Wandtafel rinnen lassen. 
 EMI1.1 
 



   Das herablaufende Wasser wird durch die Rinnen l oder o aufgefangen und   fliesst   ill den Behälter m ab. 



     Die Anordnung des Wasserbehälters   a kann auch so geschehen, dass man denselben z.   H.   bei Schiebewandtafeln am höchsten Punkte, den dieselbe erreicht, befestigt, und die Verbindung   zwischen Hahn   und Berieselungsrohr durch einen Schlauelh herstellt.

  Device for cleaning blackboards.



   The present invention has the purpose of automatically moistening the writing surfaces of a blackboard.



   In the drawing, FIG. 1 shows the overall view of the wall panel, FIG. 2 shows the section through tap b and FIG. 3 shows the section through pipes d and e.



   The idea of the invention lies in the arrangement of a water container a, on which the water flows into the pipes d and e, which in turn let the same flow onto the writing surface of the blackboard.
 EMI1.1
 



   The running water is caught by the channels l or o and flows ill the container m.



     The arrangement of the water tank a can also be done so that the same z. For example, in the case of sliding wall panels, it is attached to the highest point that it reaches, and the connection between the tap and the sprinkler pipe is established by a clever man.
