Abstract

A trash rake is disclosed for cleaning the bars of a water intake bar screen. A carriage carrying a pan is mounted for movement parallel to the bar screen. Along the transverse edge of the pan proximate to the screen is a rake member whose teeth are received between adjacent bars during one direction of displacement of the carriage. A watertight recovery gutter for collecting foreign bodies, including living creatures, is arranged in continuity with the rake member and maintains the foreign bodies in water during the ascent of the pan. Preferably, the recovery gutter has a trapezoidal cross section and a transverse wall portion running directly into the rake member which makes an angle of at least 30.degree. with a horizontal plane when the rake member engages the bar screen.
