Abstract

A screen assembly for removing unwanted material from a fluid flow comprises a rake assembly mounted on a slidable carriage which is mounted and spaced from a screen via a frame. The rake assembly have tines mounted on a shaft with a T-bar assembly which in use the tines can move from a retracted or non-operating position to an extended position and vice versa. A drive shaft mounted to the carriage and frame is operatively connected to the rake assembly whereby movement of the drive shaft causes T-bar assembly to move the tines into an extended position or non extended position which such tine movement is then followed by moving the carriage with the tines to push or remove any of materials caught on the screen, off the screen or along the screen.
