A bar screen assembly includes a bar rack interposed across a passageway. At least one rake arm for raking debris from the bar rack to an upper end of the bar rack is provided. An apron adjacent the upper end of the bar rack receives debris, and the apron is mounted to the frame for movement between a receiving position and a dumping position. A mechanism is provided to sense movement of the rake arm relative the upper end of the bar rack, and a mechanism is provided for moving the apron from the receiving position to the dumping position in response to the sensing mechanism.
