Abstract
A raked bar screen for a storm overflow comprises a grid of parallel spaced-apart bars (1) attached at their ends to a framework (2,3,14). A comb assembly (4,5,6) has teeth (5) which engage in the spaces between the grid bars (1). The comb assembly is longitudinally reciprocable, whereby the comb teeth can sweep longitudinally back and forth between the grid bars. The grid bars are shaped to provide a straight central portion (10) and longitudinal end portions (11, 12) which are angled in relation to the straight portion. In use, sweeping of the comb teeth between the grid bars at the angled end portions drives out entrapped solid matter.
