Application filed April "f,

To all whom it may concern:

Be it known that ll, WILL AM L. HILBIsH, a citizen of the United States'oi America, and resident of Fort Vlfayne, in the county of Allen and State of Indiana, vented certain new and "useful improve ments in Filters, of which the following is a specification.

This invention relates to improvements in water filters for connection inthe pipe line between a cistern or other sourcdoit water supplyandthe distributing pipe sys tern of a residence, andtheobject thereof is to provide a filteringapparatus so constructed as to admit of convenient Cleansing and renewal of the filtering material without disconnection or" the apparatus from the pipe line, and which will be easily accessible for cleansing and renewal operations.

These objects are accomplished by the construction illustrated in the accompanying drawings, in which: a

Fig. l is an elevation of a construction embodying the invention, partly broken away;

Fig. 2 is a plan view of a removable spider used in the. apparatus; and

Fig. 3 is a plan view of one of the filtering drums employed in the construction.

The characters appearing in the description refer to parts shown in the drawings and designated thereon by corresponding 7 characters.

bolts 3. Upon the exterior of the tank are a series of lugs 4 in which the respective bolts 3 are hinged, and the head 2 has a corresponding series of lugs 5 that are on gaged by thumb-nuts 6 on the bolts re spectively.

The tank has near its upper end an internal annular shoulder 7 that forms support for a cylindrical sleeve 8 which is removably positioned in the tank, there being an external flange 9 at the top of the sleeve that rests upon said shoulder when the sleeve is in position. At the bottom of the sleeve is an internal flange 10 upon which is removably positioned a preforated plate 11. A layer composed of sponges 12 is superimposed upon the plate 11, and over said layer is placed a second perforated plate 13, and in the sleeve above the plate 13 is placed a quantity of filtering material, such as 1924. Serial Ito. 794,585.

charcoal ls. The sleeve 8 has also at a point suitably distant from its upper endj aa internal shoulder '15 "upon which restsa re-- movable artnered" platel6; *and* in?that pa'rt'of the sleeve above the plate l6 are-post tioned a series or reinovable fi lter'ing dr ii'ns ll' arranged in vertical successive order) Each filtering druinco n "i'ses a hoop 18 .upon' which "is laced a head, 'c'omppsed of a series ofjsheets 19 oreoa se'woven muslin brotherfabric, '-the margins 20 of the sheets being folded over the priineter'of tliefhoop sothat the opening 21 through the'hoop" is closed 'hythehead; The drums are forced into position throughtheupper end of-the sleeve and are held frictionally in position bythe pressure of theircontact with the; in: terio'r-wall 'of the sleeve.

In the upper end of the tank 1 is positioned a spider 22, the arms 23 of which rest upon the flange 9 of the sleeve and extend over the series of drums. The outer ends of the arms of the spider are clamped between the flange of the sleeve and the head 2 when the latter is secured in place and thus the upper end of the sleeve is held in close relation with the shoulder 7. i

The lower end of the sleeve terminates at a point suitably distant from the bottom of the tank so that when the sleeve is in place therein a chamber 24. is left in the lower end of the tank for sediment.

The tank has an inlet opening 25 leading into its settling chamber, and also an outlet opening 26 leading from a point above the uppermost drum. The tank is supported upon a tubular post 27 that has communication with the tank at its lowermost point and is closed by a base 28 at its lower end, there being a draw-oil cook 29 in connection with the post for the removal of sediment from the chamber 24.

In utilizing the invention the water from the cistern passes through the tank as it is pumped from the cistern, entering the inlet opening 25 and outthrough the outlet 26, and during its passage the water rises through the sleeve and filters successively through the layer of sponges, the pack of charcoal and the drum-heads into the top of the tank from which it is discharged through the outlet into the distributing pipe (not shown).

Such sediment as accumulates in the settling chamber is periodically removed through the draw-oil cook, and when the filtering material and the drum-heads become fouled by the accumulations of foreign matter, the sleeve with its content is bodily removed through the top'ott' the tank; Access is gained to the sleeve by first removing the head 2 and the spider. The drums, the charcoal pack and the layer or sponges, as Well as the several perforated plates are then removed from the sleeve and cleansed in any suitable manner. The filtering substances and materials are thenreassembled in the sleeve, as'in the first instance, and the sleeve isreplaced in the tank in readiness for resumption of the filtering'operation.

\Vhat'l claim is: p 1.-Infiltering apparatus, a, closed tank having a removable head at its top and an internal annular shoulder in its upper part spaced from the head; removable sleeve in the tank having an external flange at its top seated on the shoulder, and an internal flange at its lower end; a series of perforated plates spaced apart and arranged in the sleeve; filter packs in the spaces between the perforated plates; a series of filtering drums positioned in vertical succession in said sleev above the uppermostor" said plates, each drum comprising a hoop and a series of fabric sheets folded over the hoop and closing the opening thereof; and a spider positioned in the space within the tank between the top of the sleeve and the removable head and extending over the series of drums, said tank having an inlet at a point beneath the lower end of the sleeve and-an outlet at a point above the top thereof.

2. In filtering apparatus, a closed tank having an internal annular shoulder in its upper portion spaced from its top; areinovable head at the top of the tank; a removable sleeve in the tank having at its top an ex ternal flange seated on said shoulder ;afiltering means removably lodgen in the sleeve; and a spider clamped by the head upon the flange of the sleeve and operable to hold the sleeve and filtering means therein in position, said tank having an inlet below the lower end of the sleeve and an outlet ata point above the top thereof.
