Abstract: A laterally moveable bar rake is provided for cleaning a bar rack installed across a water stream of a water treatment facility, storm water station or the like. The device includes a traveling framework for back and forth movement across the top of the bar rack, a telescoping arm with a rake head mounted on the lower end of the telescoping arm and a tilt mechanism for tilting the telescoping arm between raking and extension position so that the arm can be extended to the bottom of the bar rack or beyond, tilted toward the bar rack and withdrawn along the bar rack to rake debris onto a discharge hopper or conveyor.

Abstract: The present invention includes an improvement to a conventional explosion-proof electric brake motor having a motor housing, an electrical conduit attached thereto, a brake housing secured to the motor housing and having an electrical attached to the brake housing, a flange secured to the motor housing and adapted to secure the motor to a drive mounting for driving a shaft. The improvement comprises a first housing waterproof means inserted between the motor housing and the brake housing. A first conduit waterproofing means is adapted to seal the brake electrical conduit to the brake housing. A second conduit waterproofing means is adapted to seal the motor electrical conduit to the motor housing. A flange waterproofing means is adapted to seal the flange to the motor housing. Thus, the conventional electric brake motor and the waterproofing means form a submersible, explosion-proof brake motor.
