ABSTRACT:
The present invention is an air operated fluid handling apparatus for cleaning lithographic presses. It provides a printing press operator with a device for both dispensing ink solvents and removing spent fluids used in the printing process. Compressed air is regulated and directed to a T-section connector. One conduit extends from the connector to provide pressure in an ink-solvent container. Another conduit extends from the connector to a venturi which is used to create a vacuum in a used-fluid container. A conduit extends from each container and connects to a light weight flexible hose. Connected to the opposite end of the flexible hose is a valve and nozzle assembly that allows the press operator to alternate between dispensing ink solvent and remove spent fluid. With this apparatus the press operator can effectively move from printing head to printing head dispensing ink solvent and removing used fluids as necessary for ink train and dampening system cleanup.
