To aZZ` whom it may concern,.-

Be it known that I, ALoIs AUFRICHTIG, a citizen of the United States, residing at ,the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Water-Filters, of which the following is a full, clear, and exact description, reference lbeing had to the accompanying draw-1` in'gs, forming a part of this specification.

My invention relates to that class of Wateriilters employing perforated filtering-cylinders; and my invention consists in features of novelty hereinafter fully described, and pointed out in the claims.

Figure I illustrates a vertical section taken through the shell of the lter and showing the interior structure, pantin section and part in elevation. l Fig. II illustrates a horizontal section taken on line Il ll, Fig. l. Fig. III illustrates a horizontal section taken'on` line HI III, Fig. I. Fig. IV illustrates a vertical section taken centrally thrcugh one of the outer iiltering-cylinders A Fig. V illustrates a veri tical section taken centrally through one end of the central filtering-cylinder. FigVI illustrates a cross-section of one of the inlet spray Water-pipes.

ln the drawings,l designates the filter-tank, and 2 the supplypipe, provided with a valve 3. Leading from the tan-lr at each end are outlet-pipes 4, provided with valves V5. Portions -of the outletspipes i are screw-threaded Where they pass through the'tank, and Watertight connection is formed byin'cans of packing-nuts 6. p

7 designates au `outer inlet spray-pipe' connected to the supply-pipe 2 and having rows of oblquely-radial series of perforations 8 in its under side, the perforations of one row permitting a flow of Water toward the shell of the filter and the perforations of the other row permitting allow of water inwardly against the ltering-cylinders.

9 designates an inner perforated spray-pipe, the perfor-ations in said pipe being located in a similar manner to those in the pipe 7. By means of the spray-pipes 7 and 9 Iain enabled to direct the iloW of Water in the filter in down Wardly-diverging directions, so that the water reaches allparts of the filtering-cylinders the shell of the iilter.

1C designates the centrallydocated filter- 4of perforatedv tubes 17.

ing-cylinder, and 11 the'outer surrounding filtering-cylinders. The central cylinder is provided with a perforated tube 12,` having openings 13, leading into the radial channels 14 of spiders 15, located at each' end of the cylinders. The tube l2 extends through the center `of the spider 15 and is connected to the outlet-'pipes 4L at each end of the cylinder 10. Close joints between the cups 15:L of the spiders and the filtering-cylinders at each end are accomplished by nuts 16, screw-threaded to the tube 12. The outer ends of the spiderarms are providedwith cups 15b, that receive the ends-0f the outer filtering-cylinders l1. The arms of the spider 15 at the upper end of the filter are screwethreaded upon the interior of their ends and receivethe upper ends The lower ends of said tubes 17 each contain an opening 18, permitting passage of Water from the interior to the radial tubes 17 of the channels `of the lower spider, the lower ends of the tubes 17 being closedby cap-nuts 19.

The construction of theliltering-cyliuders, both central and outer, are similar and are composed of inner sleeves 2O of asbestos cloth or analogous material surrounding the perforated tubes, next to which is a filling 21 of asbestos fiber or analogous material. The filling/21 is surrounded by a perforated sheetmetal sleeve 22, and the whole is incased by a jacket 23 of asbestos cloth or analogous material.

The Water entering through the su ppl y-pipe 2 is discharged from the' spray-pipes 7 andi)V in the interior of the lilter, and, percolating through the cylinders 11, flows from the interior of the tubes 17 through the channels 14 of the spiders 15, and thus reaches the tubes I2, entering said last-mentioned tubes through the openings 13 therein.l The water percolatingthrough the cylinder l0 enters directly into the tube 12. From thetube 12 the ltered Water may be drawn olf through either of the outletpipes 4.

24 designates a reservoir located on top of the filter-tank, in which a float 25 operates. A valve 24a controls the passage to said reservoir. The upper end of the float 25.is pivoted to vone end of a rocking lever 26, supported. in a bracket 27. The Opposite end of. said lever 26 has .connected to it one endet a rod 2S the opposite end of said rod being ply-pipe valve pivotally connected to the arm 13 ofthe sup- 'lhis Iloat connection with the siip1lypipe valve causes the supply-pipe valve to be closed by the iloat rising when the filter-tank has become filled and the water has raised into the reservoir 2l. IThe ob'- Iiect-ol' this arrangement is to prevent the acccssof air into the 'lilter-tank, which would cause the water to become foul therein. \Vhen the supply-pipo valve is closed, the iiltration of the water proceeds, but is accomplished merely by gravitation. As soon as the water has escaped to any extent from the filter-tank the supply-pipe valve again opens by the falling ofthe float actuating it and water is again admitted int-o the lilter-tank.

' `When it is desired to employ the filter under pressure, the rod 2S is disconnected from the arm 3 of the valve 3 and the valve 24 isclosed, at which time, with the valve 8 open, the water is free to flow into the filter and out through either of the outlet-pipes i after filtration.

With the employment of the perforated inlet-pipes located above the filtering-cylinder and having perforations arranged to permit a flow of water in diverging directions the filter maybe readily cleansed,as the diverging streams of Water from the inlet-pipe reach the different parts of the iilterii g-cylinders and the interior of the tank.

29 designates a pipe located inthe bottom of the filtering tank "and provided with a valve 30. When it is desired to cleanse the filter, the valve 30 is opened and any accumulations of mud or dirt may be withdrawn from the filter-tank. i

,'I claim as my inventionl 1. A water-filter comprising atank having an inlet-opening, a central perforated outlettube formed with upper and lower inlet-openings and extending through the heads of the tank, the upper and lower. spiders each having central and end cups and radial channels connecting the end cups with the inlet-openings of the outlet-tube, the central perforated cylinder and filtering material surrounding the outlet-tube and seated in the central cups, the perforated end tubes connecting the end cups and the perforated cylinders and filtering material surrounding the perforated end tubes and seated in the end cups; substantially as described.

2. A water-filter comprising a tank having a supply-pipe near its upper head, a central perforated outlet-tube formed with upper and lower inlet-openings and exteondiug through the heads of the tank, the upper and lower spiders each having central and end eu ps and radial channels connecting the end cups with 'the inlet-openings of the outlet-tube, the central perforated cylinder and filtering material surrounding the outlet-tube and seated in the cent-ral cups, the perforated end tubes connecti ng the end cu ps, the perforated cylinders and filtering material surrounding the perforated end tubes and seated in the'end cups, the outer spray-pipe having oblique series of radial perforations and connected With the supply-pipe, and the inner spray-pipe having oblique series of radial perforations and connected With the outer spray-pipe; substantially as described.

3. The combination of the tank having a supply-pipe, a perforated outlet-pipe extending through the heads'of the tank, a filtering device surrounding the outlet-pipe, a valve having an arm and located in the supply-pipe, an open-top reservoir having a bracket and connected through the upper head of the tank, a lever pivoted to the bracket and on necting the arm of the valve With lever; substantially as described.
