Abstract
A dampening liquid application apparatus for a lithographic press includes a motor driven metering roller drivably engaged with a transfer roller which in turn is engageable with an applicator roller for transferring dampening liquid to a plate cylinder. The metering and transfer rollers are driven through a gear train and are mounted on support members which permit pivotal movement of the support members such that the transfer roller may be disengaged from the applicator roller and, through a lost motion coupling, the applicator roller may be disengaged from the plate cylinder. A distribution roller is engageable with the dampener applicator roller and one of the form rollers of the press inking train. The distribution roller is selectively movable to and maintainable in position in which the distribution roller is disengaged from the form roller but is engaged with the applicator roller.
