EMI2.1
Die Federn 7 und 8 haben aber auch noch den Zweck, das den Anker der Magnete 11 und 12 bildende Sperrglied 9 beim Stromloswerden der Magnete von dem betreffenden Magneten, z. B. 11, abzureissen und den Wähler damit sofort wieder für die Weiterbenutzung freizugeben.
Die hiezu erforderliche Spannung erhält die jeweils in Betracht kommende Feder, im an- genommenen Falle die Feder 7, dadurch, dass die Scheibe 6, nachdem sie das Sperrglied 9 vor den Magneten 11 gebracht hat, bis zum Auftreffen des Nockens 4 auf den Anschlag 13 noch einen gewissen Weg zurücklegt ? bei dem gezeichneten Beispiel eine Viertel-Umdrehung. Während dieser Drehung der Scheibe 6 wird zwar das Sperrglied von dem erregten Magneten in seiner äussersten Lage festgehalten, die Feder 7 aber wird durch die Scheibe 6 bereits wieder ein Stück weit nach dem andern Magneten 12 hin bewegt, also gespannt und führt daher bei der Aberregung des Magneten 11 das Sperrglied 9 sofort in seine Mittcllage zurück.
Die beschriebene Ausführungsform hat übrigens noch den grossen Vorteil, dass nur schwache Kurvensteigungen vorkommen und daher Klemmungen und stärkere Reibungen vermieden werden.

EMI2.1
The springs 7 and 8 also have the purpose of the locking member 9 forming the armature of the magnets 11 and 12 when the magnets become de-energized by the magnet in question, e.g. B. 11, to be demolished and thus immediately to release the voter for further use.
The tension required for this is given to the respective spring in question, in the assumed case the spring 7, in that the disk 6, after it has brought the locking member 9 in front of the magnet 11, until the cam 4 hits the stop 13 still covers a certain distance? a quarter turn in the example shown. During this rotation of the disc 6, the locking member is held in its extreme position by the excited magnet, but the spring 7 is already moved a little way towards the other magnet 12 by the disc 6, i.e. tensioned and therefore leads to de-excitation of the magnet 11, the locking member 9 immediately back into its middle position.
The embodiment described also has the great advantage that only slight curve gradients occur and therefore jamming and greater friction are avoided.
