Abstract
A device for driving an oscillating auxiliary gripper of a printing press includes a driven shaft having an eccentric portion thereon, the driven shaft being rotatably mounted on 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. A driven gear is rigidly secured to the driven shaft and meshes permanently with a drive gear that rotates with the impression cylinder to provide positively cooperating drive elements for introducing the desired additional oscillating motion upon the continuous orbital movement of the auxiliary gripper shaft. To this end, a trio of cams secured to the upright act on the auxiliary gripper shaft by way of cam followers disposed on a link rod rotatably mounted on the auxiliary gripper shaft and a drag lever is pivotally connected to the link rod by way of a pivot connection and is also pivotally and eccentrically connected to the driven gear by way of a pivoted connection therein for oscillating the auxiliary gripper shaft on the eccentric portion of the rotating driven shaft.
