ABSTRACT:
A dampening assembly for a printing press has its components including the water tray, fountain roller and ancillary parts mounted on a frame which is supported from the press frame by means of parallel arms. A piston or comparable device is used to swing the arms about their pivotal connections to the machine frame so as to swing the dampening assembly between an operative elevated position and a lower laterally displaced servicing position to provide access to the interior of the press for quick change-over of the printing plate and for maintenance. The supporting arms are shaped and dimensioned so as to remain parallel to one another as the assembly is moved between its two positions, thereby to maintain the assembly frame and particularly the water tray thereon substantially horizontal to avoid spillage of water.
