Abstract
A boom is mounted for pivotal movement about the center from which the arcuate shape of a filter screen is struck and a cleaner is pivoted to the free end of the boom. A single reversible drive unit is operatively connected to the cleaner for exerting a force thereto to tilt the cleaner toward a cleaning position. A stop operatively and rigidly connects the cleaner to the boom to transmit force from the cleaner to the boom as a pivotal force only after the cleaner is tilted to the cleaning position to thus rigidly connect the drive unit and cleaner to the boom.
