Overrunning coupling and control assemblies, each of which includes control apparatus having a latching mechanism are provided. Each latching mechanism prevents an actuator arm of an overrunning coupling assembly from moving in a first direction substantially parallel to a shift direction of a control plate of the coupling assembly within a housing slot in a locked condition of the mechanism in a first position of the control plate. A control pressure signal within a bore of the housing changes the condition of the latching mechanism from locked to unlocked to unlock the actuator arm and causes the unlocked actuator arm to move along the first direction within the slot and the control element to move along the shift direction to a second position. The control pressure signal also causes a piston which has a groove formed in its outer surface to receive and retain a free end portion of the actuator arm to slide within the bore in the housing against the biasing force of the at least one biasing member. In the absence of a control pressure signal, the at least one biasing member moves the piston and thereby the unlocked actuator arm in a second direction opposite the first direction within the slot and the control element along the shift direction from the second position back to the first position and changes the condition of the latching mechanism from unlocked to locked to lock the actuator arm.

An inking system of a printing press is utilized for inking a printing cylinder. The inking system is configured as a long roller inking system and includes two distributing cylinders that are disposed serially in a roller train. A first one of these distributing cylinders is mounted, in the roller train, close to the printing cylinder. The other of these distributing cylinders is mounted, again in the roller train, further away from the printing cylinder. The printing cylinder is rotationally force-driven by an angle position controlled drive motor. One of the two distributing cylinders of the inking system is rotationally force-driven by a drive motor that is mechanically independent of the drive for the printing cylinder. The other one of the two distributing cylinders is rotationally driven by frictional engagement with adjacent rollers or cylinders. It is thus configured without a mechanical drive connection to one of the drive motors other than the frictional engagement with the adjacent roller or cylinders which are intended to rotationally drive it.
