LOCOlVlOTIVE WATER-PURIFIER.

SPECIFICATION forming part of Letters Patent No. 619,303, dated February 14, 1899. Application iiled March 22, 1897. Renewed September 22, 1898.- Serial No.` 691,618. (No model.)

To all whom t may concern:

Be it known that we, NORMAN L. HAYDEN andANDREw WILDMAN, citizens of the United States of America, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Locomotive Vater-Puriiers, of which the following is a specification.

Our invention relates to certain improvements in a device for purifying water for use in steam-boilers, said improvements being designed especially for use upon locomotiveboilers.

The object of the invention is to devise an apparatus which shall effectually cleanse the water of all injurious ingredients, as well as of all dirt and sediment before it reaches the boiler, and to do this in a vessel of such a nature as to be easily accessible and readily cleaned.

To such end the invention consists in certain novel features embodied in the apparatus described in detail below, the essential portions of which will be definitely pointed out in the appended claim.

The preferred form of our invention is illustrated in the drawings presented herewith, in which- Figure l is a side elevation ofthe entire apparatus, showing in vertical diametrical section the vessel which is intended to receive and collect the dirt and impurities; and Fig. 2 is a horizontal section in line 2 2 of Fig. 1.

Referring to the drawings, A is a steam-pipe leading from the boiler. B is a suction-pipe leading from the water-supply. C is an injector connected to both of said pipes.

D is the discharge -pipe of the injector, which leads therefrom to a vessel E, in which the impurities are to be collected. Fis a pipe leading from said vessel E to the boiler.

G is a pipe connecting the pipe D with the pipe F and designed to cut out the vessel E when necessary.

H is a blow-off pipe intended for use in cleaning out the vessel E.

The steam-pipe and the suction-pipe are provided, respectively, with valves a b. The

pipe D is provided with a check-valve CZ and a gate-valve d. The pipe Gis provided with a gate-valve g. The pipe F is provided with a check-valve f, and the pipe H is provided with a valve h, adapted to close the same.

The vessel E is divided into an upper and a lower chamber by a partition e, inade up of perforated disks e e2, between which is a loose filtering substance e3. The top of the vessel is covered by a cap e4, which may be removed, and the disks e e2 are held between brackets e5 c e7 e8. Each of the disks is provided With notches e9 to enable them to pass by the brackets and with pivoted buttons e to slip beneath the brackets and secure the disk in place. Beneath each of the disks is a reticulated fabric, preferably cloth, cl2. The pipe D at the point where it enters the vessel E has a slight bend cl2, which is turned laterally and upwardly to direct the water against the cloth and in a direction substantially tangentialwith the wall of the vessel, so as to cause a sort of whirlpool and assist in keeping the cloth free from sediment that might clog it up.

The operation of the device is as follows: The steam is turned on with the valves b d open. As the steam enters the injector it draws the water from the pipe B and delivers the same at a boiling temperature through the pipe D, past the check-valve d, and into the vessel E. The boiling of the water prepares it to deposit the greater portion of 'its impurities which collect in the bottom of 'the vessel E. As the lower portion of this vessel fills the purer water at the top is forced upward through the cloth @12, the filtering substance e3, the second cloth, and into the top of the vessel, from whence it passes on through the check-valve f to the boiler. The two thicknesses of cloth cl2 and the interposed filtering material thoroughly remove Whatever sediment might otherwise fail to settle in the bottom of the vessel E. As the bottoni of the latter iills up the valve hin the blow-od pipe is opened from time to time, discharging the sediment and impurities collected. At much greater intervals the top e4 of the vessel is removed, the disks taken out, and the cloth or other reticulated fabric and interposed filtering material removed and renewed. This may all be done without interfering with the feeding of the boiler, because of the auxiliary pipe G, which furnishes IOO an independent connection between 'the injector andthe boiler and enables the purifying vessel to be cut out entirely for cleaning.

We claim as new and desire to secure by Letters Patent- In a device for purifying water for boilers, the combination with a cylindrical vessel having a filtering partition perpendicular to the axis of the vessel, cfy a boiler feeder adapted to deliver water to said vessel at a boiling temperature, a pipe leading from said feeder into said vessel on one side 'of said partition and discharging the Water into said vessel in a substantially tangential direction and toward said partition, and a pipe leading 15 our hands, at Chicago, in the county of Cook zo and State of Illinois, this 19th day of March, 1897.
