A cam projects from the bottom of the filter cake chamber and is adapted to support the filter plate on a corresponding cam on an adjacent filter plate with the cam extending substantially to the level of the outer surface of the frame of the filter plate. An opening is provided in the filter cloth covering the plate frame for receiving the cam. A clamping ring surrounds the cam and the filter cloth adjacent thereto to form a seal therebetween. A washer-like member overlies the cam and a portion of the clamping ring and retains the clamping ring in place.
