 genügend Zeit, den Drehfeldumschalter zum Umsteuern gleichzeitig zu   betätigen,  
Während in Fig. 3 angenommen   ist, dass   die entsprechend dem Stammpatente langsam bewegte Bürste beim Umsteuern eine   Zusatzverschiebung   erhält, kann man auch entsprechend
Fig. 4 der schnellbewegten Bürste diese Verschiebung erteilen. Im   crsteren Falle   muss die zu-   sätzliche Bürstenverschiebung   in demselben Sinne geschehen, in dem die langsame Bürste von dem normalen   Antriebsgestänge zur Geschwindigk@itsveränderung so wie so bewegt   wird.

   Im letzteren Falle muss die schnellbewegte Bürste beim Umsteuern immer um ein gewisses Mass zurückgeschoben werden, um in die der neuen Drehrichtung entsprechende Stellung zu gelangen. 



   Anstatt der zusätzlichen Verstellung der Bürsten beim Reversieren, die einen für beide
Drehrichtungen geordneten Betrieb des Motor mit günstigem Wirkungsgrad und   gün-iigster

While it is assumed in FIG. 3 that the brush moving slowly according to the parent patent receives an additional shift when reversing, one can also accordingly
Fig. 4 give this displacement to the rapidly moving brush. In the worst case, the additional brush displacement must take place in the same way as the slow brush is moved by the normal drive linkage to change the speed.

   In the latter case, the rapidly moving brush must always be pushed back a certain amount when reversing in order to get into the position corresponding to the new direction of rotation.



   Instead of the additional adjustment of the brushes when reversing, one for both

    Finally, it is also possible to switch on different types of brush systems for left and right rotation of the motor.
