An ink fountain for printing machines is disclosed. A plurality of ink metering elements are placed side by side in contact with each other in a longitudinal gap formed in an upper bottom surface of an ink fountain bottom. The longitudinal gap extends parallel to the axis of rotation of the ink fountain roller. Each ink metering element is rigidly secured to a pivotable arm that extends through a vertical opening which passes through the side of the ink fountain bottom opposite the inner bottom surface. Movement of the pivotable arms adjusts the metering slots formed by the ink metering elements and the ink fountain roller periphery. The longitudinal gap is sealed adjacent the inner bottom surface and the pivotable arms and a lubricant completely fills the chamber defined by the longitudinal gap and the vertical openings. Dirt and ink are prevented from interferring with the smooth operation of the ink metering elements since any dirt or ink which may pass by the seals is taken up by the lubricant in the chamber. |
