ABSTRACT:
For use with an ink fountain having a trough with a flat sloping bottom wall and a fountain roller at the presented edge of the bottom wall, a moveable partition for dividing the trough into adjacent feeding and non-feeding areas. The partition consists of a trough-engaging portion having a straight face for engaging the bottom wall of the trough and a separate roller-engaging portion having an arcuate face for engaging the roller surface. Resilient sealing strips are secured to the faces thereof for sealing against the flat bottom wall of the trough and the cylindrical surface of the roller. The two portions are so arranged that their adjacent edges overlap to block the escape of ink, and are connected one to the other by a pivot which extends parallel to the roller axis in the region of the overlap. The pivot is fitted loosely to provide play in the plane of the partition so that when the trough-engaging portion is clamped downwardly and forwardly in the direction of the fountain roller, the roller-engaging portion is free to undergo rocking and translational movement for intimate seating of the arcuate face thereof on the fountain roller notwithstanding variations in the transverse positioning of the roller axis vertically and horizontally with respect to the bottom wall of the trough.
