  • Patent number: 5387336
    Abstract: The invention concerns a screening rake for removing solids from flowing sewage, the rake having a driven screening belt which can be immersed in the sewage and which has two lateral chains. A group of screening elements fitted with hooks is mounted on each of two support rods independently of the preceding and following group of screening elements. The screening elements in each group have extension pieces which project beyond the two associated support rods in the direction of travel of the screening belt and in the opposite direction. The extension pieces of successive groups of screening elements engage with each other like the teeth of a comb.
