kraft und somit das nach aussen wirkende Moment grösser wird und zur Wirkung kommt.
Das Gewicht a entfernt sich nun vom Punkt c (Drehpunkt der schwingenden Masse), und zwar soweit, bis das Drehmoment, wie oben erwähnt, wieder kleiner geworden, d. li. so gross wie das Gegenmoment ist. Es bewegt sich also das Gewicht a allmählich bei steigender Umlaufzahl nach aussen, während es bei abnehmender Umlaufzahl sich langsam zurück nach innen bewegt.
Das Gegenmoment wird nun gemäss der Erfindung durch Anheben des Gewichtes in Richtung seiner Drehachse erzeugt. Zu diesem Zweck ist bei der Ausführungsform nach Fig. 1 und 2 die Drehachse der Gewichte als Schraubenspindel d ausgebildet, während bei Fig. 3 eine schiefe Ebene./* vorgesehen ist, auf der das Gewicht hochsteigt. Fig. 2 zeigt in punktierten Linien die Ruhe-, d. h. Innenlage der Gewichte und in ausgezogenen Linien die Aussenstellung derselben.
PATENT-ANSPRÜCHE :
1. Antrieb für freischwingende Plansichter mit exzentrisch angeordneten, horizontal drehbaren Schwanggewichten, dadurch gekennzeichnet, dass das oder die in der Schwung- scheibe angeordneten Gewichte in Richtung ihrer Drehachse verschiebbar sind.

force and thus the outwardly acting moment becomes larger and takes effect.
The weight a now moves away from point c (pivot point of the oscillating mass) until the torque, as mentioned above, has decreased again, i.e. left as big as the counter-torque is. So the weight a gradually moves outwards as the number of revolutions increases, while it slowly moves back inwards as the number of revolutions decreases.
The counter-torque is now generated according to the invention by lifting the weight in the direction of its axis of rotation. For this purpose, in the embodiment according to FIGS. 1 and 2, the axis of rotation of the weights is designed as a screw spindle d, while in FIG. 3 an inclined plane./* is provided on which the weight rises. Fig. 2 shows in dotted lines the resting, i.e. H. Inner position of the weights and the outer position of the same in solid lines.
PATENT CLAIMS:
1. Drive for free-swinging plansifers with eccentrically arranged, horizontally rotatable pregnant weights, characterized in that the weight or weights arranged in the flywheel can be displaced in the direction of their axis of rotation.
