ABSTRACT:
For imparting end-to-end vibration to an inking roller in a printing press, a worm is fixedly mounted on one of the opposite trunnions of the inking roller. A worm wheel in mesh with the worm is rotatably carried by a reciprocator which is mounted on the trunnion for vibratory motion therewith but which permits its rotation. An eccentric shaft extends eccentrically through the worm wheel for simultaneous rotation therewith about the axis of the latter. A pair of offset extensions projecting eccentrically from the opposite ends of the eccentric shaft are engaged in stationary guideways and thereby constrained to rectilinear reciprocation in a direction normal to the trunnion axis, for transforming the rotation of the worm wheel into the endwise vibration of the inking roller via the reciprocator. The amplitude of the vibration can be varied stepwise by causing angular displacement of the eccentric shaft about its own axis with respect to the worm wheel and by locking the eccentric shaft to the worm wheel in a desired angular position.
