ABSTRACT:
A self-cleaning trash rack for removing debris from a stream of water has an upright frame positioned in the path of trash carried by the stream and a plurality of endless, flexible chains carrying trash supports which engage and carry debris on the upstream side of the frame upwardly for disposal. Each chain has sufficient slack to enable any trash support on the upstream side of the frame to rock in such direction as to release debris that is too heavy to be carried upwardly by such trash support.
