ABSTRACT:
The invention relates to a transmission mechanism for imparting rotational movements to a driven member by means of a reciprocating drive member. The mechanism comprises means pivotally connected to the drive member for alternately actuating two dogs of an operating unit associated with the driven member so as to move the operating unit to one or the other of two end positions, thereby providing said rotational movement of the driven member. The means for actuating the operating unit is an arm capable of pivoting to and fro across a central plane through the travel path of the drive member, said arm being arranged to effectuate the alternate actuation of both the dogs by one and the same free end thereof, power means for moving the operative unit to the respective end positions being pivotally mounted in relation to a stationary pivot and having a point of action being opposed to said pivot. This point of action of the power means follows the operating unit when moving this between said end positions.
