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

beiden Bürstensätze mit in Kauf nehmen müssen.
Schliesslich ist es auch möglich, verschiedenartige Bürstensysteme jeweils für Linkslauf und Rechtslauf des Motors einzuschalten.
PATENT. ANSPRÜCHE : 1. Einrichtung zum Umsteuern von Wechselstromnebenschlussmotoren mit Energiezuruhr im Rotor und Bürstenregelung nach Patent Nr. 69923, gekennzeichnet durch eine derartig Verstellung oder Vertauschung der Kollektorbürsten bei der Umschaltung des Drehfeldes, dass

enough time to operate the rotary field switch to change direction at the same time,
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
Direction of rotation, orderly operation of the motor with favorable efficiency and cheapest

have to accept both sets of brushes.
Finally, it is also possible to switch on different types of brush systems for left and right rotation of the motor.
PATENT. CLAIMS: 1. Device for reversing AC shunt motors with energy supply in the rotor and brush control according to patent no. 69923, characterized by such an adjustment or exchange of the collector brushes when switching over the rotating field that
