ABSTRACT:
A wheel supported bridge transversely spans an upwardly open settling tank having a horizontal bottom. The bridge is automatically reciprocated by friction wheels between the ends of the tank. Support members, depending from the bridge, are pivotally connected with a scraper frame having a scraper element drawn across the tank bottom in a sludge collecting and removing action, when the bridge is moved in one direction. The scraper element is disposed in an idle position spaced above the plane of the tank bottom when the bridge is moved in an opposite direction. A counterweight, supported by the scraper element frame, maintains the scraper element in operative or idle position when the scraper frame is disposed in its respective position.
