ABSTRACT:
A water fountain for a dampening unit of an offset rotary printing machine includes spaced front rear and side walls and a bottom. A pair of spaced inlet and outlet dams each include drainage holes and overflow apertures. Dampening fluid is fed to the fountain through an infeed pipe and unused fluid exits the fountain through a drainage tube. This drainage tube is in fluid communication with, but is separate from a funnel carried in an open end of a dampening fluid recirculation pipe. The water fountain is supported between side frames of the press. Since neither dampening fluid inlet line nor the dampening fluid recirculation pipe are connected to the fountain, it can be quickly and easily removed from the dampening unit for cleaning or service.
