ABSTRACT:
An ink fountain having a metering assembly in the form of a series of rectangularly shaped slides fitted into a horizontal slot in a frame with only the presented front ends of the slides being exposed and abutting the fountain roller. The slides are arranged side by side in coplanar relation with their lateral edges lying closely adjacent one another. Notches are formed in the lateral edges of the slides adjacent the front ends thereof, with the notches being occupied by slightly oversized buttons of resilient sealing material. The metering assembly is held captive at its ends between two vertical end plates which apply inward squeezing pressure to the metering assembly so as to compress the resilient buttons uniformly to bring the lateral edges of the slides into snug sliding relation to prevent leakage of ink between them and for the purpose of distributing any cumulative tolerance error equally between all of the slides in the series. Means are provided for confining the rear ends of the slides so that all the slides of the series are oriented precisely parallel to one another. Each of the slides has provision at its rear end for longitudinal adjustment in the form of an eccentric mechanism having a shallow throw. Each of the slides has a shank portion which is laterally relieved over the major portion of the length thereof so that the lateral edges of adjacent slides are in engagement only at the front and rear ends.
