ABSTRACT:
A traveling water screen has trays that travel one after the other along a path in the form of a vertical loop. Adjacent trays are connected for articulation about an axis extending transversely of the path. Each tray has a transverse member extending parallel and adjacent to the axis, with one member leading the other member in the direction of tray travel. The trailing member has a cross-sectional shape that extends linearly outward of the loop and curves about the axis of articulation both outwardly and forwardly relative to the path of travel. The leading member has a cross-sectional shape that extends outwardly of the loop beyond the curved portion of the trailing member to an outer edge where an extension projects rearwardly towards the curved portion. A flexible seal that is mounted on the leading member overlaps and contacts the curved portion of the trailing member on the opposite side thereof from the axis of articulation. In a preferred form of the invention, the seal is mounted to the leading member by a fastener that can be both fastened and removed from outside of that member.
