SELF-TRIMMING OSCILLATING SYSTEM

摘要

The present invention relates to a self-trimming oscillating system. This system comprises a wing like member (5) pivotally mounted on an elongated lever (3). It also comprises reciprocating connecting (49) means adapted to cause articulation of the elongated lever (3) on the one hand and to be rotatably associated with a crank means (45) on the other hand. Means (57) responsive to reciprocation of the connecting means causes oscillation of the wing (5) as the elongated lever (3) is articulated.
