Abstract
A chamber filter press embodying movable filter plates suspended for movement along horizontal guides by an endless transporting assembly driven by a reversible motor and carrying dogging members which cooperate with cams on the filter plates as the press is opened. A switch connected to a time control device reverses the motor when the filter plate which has just been moved rests against the previously moved filter plate and at the end of a preset time the time control device switches the motor from reverse to forward motion. The motor is stopped by a limit switch which is operated by a dogging member at the end of a preset time after the last filter plate has been moved forward.
