  Winkelmesser. 
 EMI1.1 
 am Scheitel des Winkels angebrachten Transporteur.   Die Aufklappsfähigkeit   des Winkelmessers erstreckt sich von 0 bis   130   und von 180 bis 75. 



   Da an dem Transporteur die Grade für leichte Ablesbarkeit zu klein sein würden, und ein korrektes Einstellen unmöglich wäre, ist in   der Innenfläche des Transporteurs   noch eine ZehntelAblesevorrichtung angebracht. 
 EMI1.2 
 von vier Spitzen versehen, so   dass,   wenn eine Spitze   die Skal : < verlässt, gleich   die nächste Spitze in Aktion tritt. 



   Im Innern des Transporteurgehäuses ist (Fig. I) ein feststehendes Rad a mit 90 Zähnen ungeordnet, mit welchem ein Trieb C mit 10   Zähnen   in Eingriff ist, an dessen über das Gehäuse hinausreichenden Lagerwelle der aus vier Spitzen bestehende Zeigergang befestigt ist. 



   Fig. III zeigt ein Rad mit 180 Zähnen und einen Trieb mit   20   Zähnen. 



   Der Vorgang beim Messen eines Winkels ist folgender : Um einen Winkel zu messen, zieht 
 EMI1.3 
   und   auf der Zehntel-Ablesevorrichtung die sich noch ergebenden Einergrade des eingestellten Winkels, wobei die Klemmschraube g angezogen werden muss, um den angegebenen Winkel in seiner Stellung zu erhalten. 



   PATENT-ANSPRÜCHE : 
1. Winkelmesser   mit   einem im Scheitel des Winkels angebrachten Transporteur, und einer 
 EMI1.4

  Protractor.
 EMI1.1
 at the top of the angle. The protractor can be opened from 0 to 130 and from 180 to 75.



   Since the degrees on the conveyor would be too small for easy readability, and correct setting would be impossible, a tenth of a reading device is still attached in the inner surface of the conveyor.
 EMI1.2
 provided with four points, so that when one point leaves the scal: <, the next point immediately comes into action.



   Inside the conveyor housing is (Fig. I) a fixed wheel a with 90 teeth disordered, with which a drive C with 10 teeth is in engagement, on whose bearing shaft extending beyond the housing the pointer gear consisting of four points is attached.



   Fig. III shows a wheel with 180 teeth and a drive with 20 teeth.



   The process of measuring an angle is as follows: To measure an angle, pull
 EMI1.3
   and on the tenth reading device the still resulting units of degrees of the set angle, whereby the clamping screw g must be tightened in order to obtain the specified angle in its position.



   PATENT CLAIMS:
1. Protractor with a feed dog attached at the vertex of the angle, and one
 EMI1.4
