Trash catching device

Abstract

An endless screen extends around an upper roller, above the stream of a ditch or the like, and a lower roller, submerged in the stream. A cleaning brush engages the underside of the lower reach of the screen, the brush rotating in a direction opposite to the movement of the screen, while a roller or rod supports the screen just below the brush. The brush may be driven directly from a motor and speed reducer, with a belt drive to an upper pulley producing further speed reduction, or a speed reduction drive between the motor and the brush with a belt or chain drive to the upper roller may be utilized. The lower roller for the screen has a fixed center surmounted by a plastic or rubber bushing about which a cylinder of the lower roller rotates. A weir directs water onto the screen, the weir including a transverse partition mounted in the ditch and having a rectangular slot therein. A rectangular funnel occupies the slot, having a base member extending to the screen and side members extending to side plates mounted on bars of a frame, with the forwardly extending members inside the plates.
