Abstract

A device for driving an oscillating auxiliary gripper of a printing press includes an eccentric shaft rotatably mounted in the side upright of the press and on the eccentric portion of which a cam-actuated auxiliary gripper shaft is rotatably mounted for oscillation thereon rotation with a driven gear being rigidly secured to the eccentric shaft and meshing permanently with a drive gear that rotates with the impression cylinder of the press is arranged to provide positively cooperating drive elements and coaxiality of the input and output shafts for introducing the desired additional motion superimposed upon the continuous rotation of the lifting eccentric of the auxiliary gripper. To this end, an auxiliary cam and main cam are rigidly secured to the eccentric shaft coaxially with the driven gear and are positively connected by way of a double cam follower lever having a pivoted connection in the frame and a pivoted connection through a crank link to the drive or input side of a differential planetary transmission on whose output side the auxiliary gripper shaft is rotatably disposed for oscillation on the eccentric portion of the rotating eccentric shaft.
