ABSTRACT:
A screen disposed in an elongated sewage channel is cleaned by the movement f a screen comb along the vertically disposed, spaced apart bars of the screen from the bottom to the top. The screen comb is pivotally attached to the end of a rake arm which is formed of a single elongated element. The opposite end of the rake arm is pivotally attached to one end of a support arm (which support arm is pivotally attached at its opposite end to a fixed supporting structure). At a point along the length of the rake arm it is pivotally attached, by way of a laterally extending pin, to a single endless chain moving along a single guide track. Thus, the rake arm is supported in cantilever fashion from the guide track. A supporting roll around the laterally extending pin at a point supported by the guide track allows the pin (as well as the rake arm) to be moved by the endless chain along the guide track. The rack arm and the guide rack are mounted behind the screen in a channel such that their cross-sectional vertical central planes are equidistant from a longitudinally vertical central plane passing through said flow channel.
