ABSTRACT:
An ink fountain for a printing press includes a fountain roller that is driven intermittently by a variable stroke drive mechanism which is actuated by an eccentric. However, instead of varying the length of linkages between the eccentric and the roller to obtain the variable stroke capability, the present mechanism employs constant length linkages coupled to the fountain roller by way of a wrap-spring overrunning clutch. A stop plate adjustably positioned by a hand wheel is arranged to stop the rotation of the clutch sleeve after it has rotated through a selected angle thereby to disengage the clutch. Thus, as the eccentric rotates, it oscillates the clutch input drum through a constant angle. However, the clutch output drum and therefore the fountain roller are advanced through a stroke angle that is continuously variable depending upon the adjustment of the hand wheel.
