Abstract
The invention relates to a drive mechanism for connecting an input shaft to an output shaft and superimposing on the output shaft a variable oscillatory motion determined by the position of a reaction member. The drive mechanism comprises an input disc fast in rotation with the input shaft, and defining a slideway transverse to the axis of the input shaft. A sliding member is made to slide along the slideway by a block journalled within a pivotable yoke, the block being itself slidable in a second slideway defined by the sliding member. A crank pin fixed to the output shaft is connected slidably to the sliding member such that as the sliding member slides along the slideway, the phase of the output shaft is varied with respect of the phase of the input shaft. A second similar mechanism drives a weight with opposite phase in order to cancel out the reaction torque on the input shaft.
