l Claims.

This invention relates to filters as used principally for household purposes by attachment to the kitchen faucet, and has for its object'an improved construction provided with means for separating impurities from the water, and means for collecting the impurities at a point out of the main stream of water and away from the Also my improved constructhe device including the filtering surface by the main stream of water coming through the faucet Without removal of the device from the faucet. Other advantages will appear in the following description and accompanying drawing.

In the drawing Fig. l is a vertical section of my filter as applied to a faucet.

Fig.2 is a sectional view of the device as seen from line 2-2 of Fig. l, the main filter device appearing in plan beyond the section line.

In detail, the filter comprises a vertically disposed hollow main cylindrical body I, having a base cap 2 of generally conical form screwed over the lower open end of the body at 3, the apex of the cap being lowermost, and a vertically directed interiorly threaded opening 4 is provided through the apex of the cap which opening is fitted with a threaded plug 5.

The cylindrical body is divided by a horizontal partition 6 about midway of its upper and lower ends which partition is formed on its underside with an annular shoulder or ledge 1 against which is sealed one or more filter screens or cloths 8 in the shape of circular disks, which disks held in place by a coil spring 9 engaging around the periphery of the disks and between the disks and inwardly projecting ledge ill formed around the upper or base end of conical cap 2. A light sheet metal cone II is positioned within the cap 2 with its conical end in vertical alignment with the opening 4, and having a flange H! at its base end interposed between the lower end of the coil spring and ledge H3, said cone H being of greater angularity than cap 2 thereby providing a space l3 between the outer side of the cone l l and undersides of cap 2 to form a dirt trap, a small opening I4 being provided at the apex of cone II to permit impurities in the water to pass into said space l3 from the enlarged space l5 between the cap 2 and partition 6.

Above the partition 5 there is a vertically extending cylindrical chamber l6 opening outward- 1y at the upper end of body I and interiorly machined to provide a close bearing surface for a cylindrical plug N that extends about to the upper end of the body I, the upper end of the plug which extension extends outwardly of the body and is threaded at its upper end to attach a pipe fitting !9 that is interiorly threaded at its upper end for securing rigidly end of a faucet 20.

An upper cap 2| is screwed over the upper open end of body I, which cap carries a packing nut and packing 22 embracing the extension H] to form a liquid seal around the extension at the upper end of body l. A coil spring 23 is interposed between the upper end of plug ll and the cap 2| and disks 2% of light resilient sheet metal are interposed between the lower end of plug l1 and the upper side of partition-6 to insure a tight seal. 1- i The plug l1 and extension 13 may be cast with a central vertical bore 25 that extends laterally at a point just above the bottom of plug I! as at 26 to the outside of the plug, or the plug and extension may be drilled out of a cylindrical bar formed to the desired shape.

At one side of the body l, a duct 28 communicates between the upper chamber it at its upper end at the level of the lateral outlet 26, and at its lower end duct 23 communicates with the upper end of space or chamber it below the partition 6 and filter screens 8.

On the side of chamber l6 opposite the upper end of duct 28 is an opening 29 that communi cates with the inner end of a bore 30 through a laterally and downwardly projecting spout 3|. The inner end of bore 30 also communicates with an opening 32 communicating between space 33, that is, above filter screens 8 and below partition 6.

In operation, the filter body is rotatable on plug I1 and extension l8, and normally is positioned so that the water from the faucet will pass through bore 25, 26, duct 28, space l5, opening 32 and out through bore 30. The fiow is therefore upwardly through screens 8 and any impurities stopped by screens 8 will settle through space l5 and through opening M in cone l! to be trapped in space it between the cap 2 and cone H from which trap they can readily be drained through opening 4 after removal of plug 5.

However, some of the finer impurities will tend to stick in screen 8, and these are quickly removed by merely rotating the body I so that port or outlet 26 will register over opening 29, and in this position the operator may merely place his finger over the outlet of spout 3i] and turn on the faucet, thus reversing the flow of water to the threaded plug 5 being removed, such impurities as well as any collecting in spaces l5 and [3 will be flushed out through opening 4.

If desired a gate 35 may be provided on the outlet end of spout 3| to close the outlet, instead of the operation using his finger. In the drawing, such gate is indicated as having arms 36, pivoted at 31 to the sides of the spout and the gate is resiliently held against the end of the spout by a coil spring 38, a square guide post 39 on the gate slidably extending through cross-bar connecting the ends of the arms behind the gate.

After cleansing the filter screen as described, the body I can then be turned back to the position indicated in the drawing.

Replacement of screens 8 is readily accomplished by removing cap 2 and spring 9 and merely inserting the new screens and replacing the cap and'screen.

Having described my invention, I claim:

1. A filter of the-character described comprising a hollow -body having 'an upper and a lower chamber therein and "a partition between .said chambers, a nozzle 'at one side of the body arranged with its bore communicating .at its inner end with the upper and lower chamber, a duct communicating between the upper and lower chamber at its opposite ends respectively and a plug rotatably fitted in said upper chamberhaw ing a bore therethrough one end of said bore in the plug registering over the end of said duct communicating with the upper chamber and the bore of the plug being adapted to communicate with the boreof the nozzle when the body is rotated relative to said plug, a filter screen extend- 'through screens 8 and cleansing the screens, the

ing over the end of that portion of the bore of the nozzle that communicates with the lower chamber, said lower chamber being provided with an opening at its lower end and a removable plug fitted in said opening.

2. In a construction as defined in claim 1, said rotatable plug in the upper chamber being provided with a vertical extension having a bore therethrough in extension of the bore through the plug and means at the upper end of said vertical extension for securing to the outlet'of a faucet.

3. A filter of the character described comprising a hollow body having a partition therein dividing the body into an upper and a lower chamher, said upper chamber being provided with a pair of spaced outlets in its side walls, a valve member rotatably fitted within said upper chamber andagainst said partition, said member having an inlet and an outlet, the outlet being positioned to selectively register with the spaced outlets in the side of the chamber upon rotating the member and body relatively. A filter screen fitted across said lower chamber, a duct communicating between one of said outlets and the portion of the lower chamber on one side of said screen and a duct-communicating between the other of the outlets and the :portion of the lower chamber on the opposite side of said screen, and a discharge nozzle arranged with its bore communicating with said last mentioned duct.

4. In a construction as defined in claim 3, means for closing the bore of the nozzle to flow of fluid therethrough and means on said valve member for securing the same to a faucet with its inlet over the discharge end thereof.
