ABSTRACT:
An ink fountain for a printing press in which the fountain blade extends at an angle to the surface of the fountain roller, with adjusting pins engaging the free edge of the blade at spaced points to determine the thickness of the ink film. Each pin has a lever extending transversely of the pin at its outer end, the lever being fulcrumed with respect to the frame and having first and second relatively spaced points of engagement. The first point of engagement presses against the outer end of the pin and the second point of engagement bears against a manually rotatable key which is threaded into the frame, each pin having a return spring for urging the pin outwardly with respect to the frame so that when the key is rotated, the lever rocks about its fulcrum to advance the pin inwardly toward the blade with positive action against the restoring force of the spring. In addition, a retainer spring on each lever holds the lever in operative engagement with the key, with such spring being yieldable so that the lever may be bodily swung about the pin axis clear of the key for retraction of the lever and pin for periodic cleaning away of accumulated ink.
