ABSTRACT:
A device for selectively controlling the manual or automatic operation of inking or damping rollers of a printing press wherein the torque which produces the adjusting movement is transmissible through a non-positive coupling and a spring-biased manually releasable and automatically engaging connecting element, characterized in that a first start-stop lever is connected to an input coupling member for the automatic starting and stopping of printing, an operating lever is connected to a handle for manual control of the starting and stopping of printing and a second start-stop lever is connected to an output coupling member and is operative to engage and disengage the rollers. The first and second start-stop levers and the manual control lever are mounted concentrically about one another on a cylindrical dowel secured to the press frame, first coupling means including a spring-biased, radially movable locking pin for normally coupling the first and second start-stop levers together, second coupling means including a peg connected to the handle and being radially movable in the operating lever for biasing the locking pin out of coupling engagement with the second start-stop lever and for simultaneously coupling the operating lever and the second start-stop lever together for manually controlled movement of the output member independent of movement of the first start-stop lever and the input member.
