Claims.—(1.) In water-purifiers, a casing divided into three chambers by horizontal divisional plates, an inlet leading to the top chamber, an outlet leading from the bottom chamber, and communication between the top and middle chamber, in combination with hollow pillars of porous stone arranged vertically within the middle chamber, and apertures formed in the lower divisional plate, over each one of which a hollow pillar rests, substantially as specified. (2.) In water-purifiers, a casing divided into three chambers by horizontal divisional plates, an inlet leading to the top chamber, an outlet leading from the bottom chamber, an aperture in the top divisional plate, a slide-valve adapted to cover and uncover such aperture, and a pipe, controlled by a valve, leading from the bottom of the middle chamber to outside the casing, in combination with a number of hollow pillars of porous stone arranged vertically within the middle chamber, apertures formed in the lower divisional plate, over each one of which a hollow pillar rests, and a number of perforated pipes opening from the top chamber and extending downwards through the middle chamber interspersed with the hollow pillars, substantially as specified. (3.) In water-purifiers, a casing divided into three chambers by horizontal divisional plates, an inlet leading to the top chamber, an outlet leading from the bottom chamber, communication between the top chamber and middle chamber, apertures formed in the bottom divisional plate and arranged in concentric circular rows, hollow pillars of porous stone mounted vertically within the middle chamber and one of which rests above each of the apertures in the divisional plate beneath, concentric rings secured within the middle chamber vertically above each ring of pillars, set-screws passing through such rings, and caps adapted to fit upon the tops of the hollow pillars and to be held in position thereon by means of the set-screws, substantially as specified. (4.)
