ports leadingto a'nozzle, and an inner valve casing or portion having a single discharge port or opening therein, whereby partial turning of the outer valve casingwill permlt a flow of water through a predetermined discharge port in the outer casing, ora, stoppage of said fiow.

Another feature of the invention is the provision .of adjustable means to regulate and determine the extent of turning -movement desired. 1 a L A further object ofthe invention resides in the provision of novel means to permit. a gradual turning on and; shutting off of the water flow through a desired port. To accomplish this last mentioned desirable, result-,I- incline the ports in the outer valve casing angularly with-respect to the single port in the inner fixed valve casing. Thus, when a port in the outer valve casing is brought into register with the portin the inner valve casing, there will be a gradual flow of the water into said outer casing port, because of its angular position; This will eliminate the objectionable pounding common in water valves. Conversely, when the flow of water is shut off from said discharge port, such stoppage willbe gradual instead of abrupt. V I

A further objectof the invention'resides in the provision of means associated with one of said discharge ports to act as a sediment collector to prevent the passage of sediment through a certain one of said nozzles, and means vassociatedwith another of Said .port in inoperative position;-

clear the'inner casing of said sediment;

The. above and other features and :objects of the invention, details of construction, combinations of parts, and advantages,.will ;be I

hereinafter more fully pointed out, described and claimed.

Referring to the drawings, illustrating a preferred; embodiment of the-invention, V

Referring now to the drawings, for aparticular description of the invention, my novel valve may be applied to an ordinary faucet, which of course has a separate turning plug therein, or may be, and preferablyjis, as shown, threaded directly onto a supply pipe 1 having a reduced threaded'portion 2 upon which the upper part'ofmy novel valve: 3 isfitted by a correspondingly internal threaded section 4, the upper portion of said valve being formedas a nut to enable a tight union to be obtained between the threaded portions 2 and 4:. g The valve 3 comprises a fixed. internal member or casing of the valve, having a downwardly extending portion 5 having a discharge ports to act as flushing means to cored recess 6 therein, through which portion 5 a port 7 is provided. The turning or rotatable portion of the valve comprises the outer member 8 carrying a nozzle 9 on one side, and a second and upwardly extending nozzle 10 approximately 90 apart.

Opening from the rear of the nozzle 9 is a port 11 adapted to register with the discharge port 7 in the fixed member 5, when these two ports are brought into alinement by the rotation of the outer casing 8. A port 12, at the rear of the nozzle 10, is provided in the casing 8 to register with theport 7, when said two ports 12- and 7 are brought into alinement. Rotative, movement .of the nozzle carrying casing '8 serves to either -shut air the central port entirely, preferably when moved as illustrated in Figs. 5 and 6, with said port 7 positioned between the ports 11 and 12,101

by slight turning movement or rotation in "eitherdire ctio'nto register or alin'e theport 7 tea anagram Fig. 7 inclined, or with slanting wa1ls,so thatthe admission of water thereto from the port 7 is'gradual when bei n-g turned into open position. Similarl in turning the casing 8 to shut oil? a flow of water from the nozzle 10, the turning off action will be gradual and not sudden or abrupt. Such gradual supply and shu't oft', p vents undue pressure in the piping, and

strain, poundiirgf, the like, d ta the sudden stopping orxstartin'g of the current flow. I preferably also form the port 11 in- Cli'ned re1a'tive1'y to the port 7, similar fto'the port 12, with the exception that the port 11 a is of greater area than the port 12, as shown in the structure of the drawings.-

In order to more 'efi'ectually control the turning movementor rotation of the casing 8 and especially to limit its rotation to just the rightpo'sition fer the nozzle 10, I provide automatic "stop, "comprising a,boss 14 rel-med on the ripper part 3 of the fixed valve member, and a collar 15, which may be e'lamped about tlie'nOzZle 10 in any desired position, said c'olla r having one arm extendingsufliciently, 'asshown in Fig. 2, to engage {the stop 14. I preferably form the collar 15 also as'a clamp, having the longer arm '16 of sufiioi'ent length to strike against the to gle, as just expl'ained, with a shorter arm 17 united thereto by a screw 18 to clamp the collar firmly upon the nozzle 10 and at proper height and position to accurately registeror faline the port's 7 and Thisjfeature is most "important, insuring quick and receive a set screw 19 which will further serve to hold the valve upon the pipe 1 carrying it, and prevent the displacement of the valve through constant swinging of the easing 8 and the nozzles carried thereby.

As illustrated in Fig. 3, I form the two members 5 and 8 of slightly wedge shaped contour, in order toinsure a snug, watertight fit, while still permitting rotation of one upon the other. To hold the two memberse and 8 in assembled position, I provide a central depending stud 20 on the lowermost portion of the fixed valve member 5, which stud has a reduced portion threaded to receive a nut 21. .A washer 22 fitted over the stud 20 and of appropriate-diameter to bear against tl'fe lower rim-of theouter or turning casing 8 (see Fig. 3)" enables the two membars, 5 and 8','to'-be' held firmly in position, adjustment 'of the nut 21' 'ac'ting to tighten said members to a water-tight contact-. To further insure water-tightness of the valve, await-as to provide a lubricant therefor, I leave a recess between the uppermostrim f "the outer-casing 8 made shoulder 23 in the fiired portion 5,"filling said recess with any i "bi e"lubricatingpacking 24, and fitting a b'a drawing 25' thereover to provide a positioni The ring 25 is wedged over aredilcedrpa-rt of thefi'xed member 3 and overlaps theedge of the rotatable casing 8, su'f I ficient space being provided between a the sheared inember "8 to permitti ghtem ing- 0f the ma 21 from time to time to compensate for wear. A washer 26,=-i'sfalso fitted "'o'n' an internalshoulder 27 in the upper portion '3 to makea atertight j Quit be-tween are eomplemental threaded sections 2 and 4. Another impo'rtant feature of my valve, especially desirable when used in "connection with a filter on one nozzle, is the provision of my novel sediment 'colle'cti ngfm'ea'n's for the filter "carrying -'nozzle,"and cooperating sediment flushing means forthe free flowing I nozzle. 7 r 7 My preferred construction for carrying out this; feature consists in forming the port 12 inthe filter carrying-nozzle 10 so as to reappearance-arid to retain the packing in. g

ceive the flow of water from the upper portion 7 of the recess or valve chamber 6, which port u alsois of reduced area to cut-down the flow of water therethrough, forming a regulated fl ow throuh the recess 6, thus further permitting sediment to settle therein. Theisettling of said sediment is further increased by the goosen'eck arrangement or shape of the nozzle the port 7 a flvalfl 28 is formed, constituting a sediment collectingfpocket in thebottom' of line 29. When the casing 8 is turned to open the free flowing port 11, which port has a depth equal to that of the port 7, the sediment collected below the dotted line 29 is at once washed out, aided by the increased volume and flow permitted by the larger port 11. Thus a filtering valve together with an automatic cleaning of said valve is produced which I believe to be a distinct novelty in this art, and therefore I claim the same broadly in the present application.

As the flow of water through a filter is relatively slow at all times, the reduction in the supply to the filter renders no inconvenience in the serivce and greatly prolongs the life and usefulness of the filter itself. The arrangement of the sediment collecting pocket in connection with the filter nozzle furthermore greatly aids in keeping the filter packing clean, irrespective as to whether or not my improved type of filter is used or other water filters.

The operation of my valve will be readily understood. With the fixed portion threaded onto piping and the outer casing fitted thereon, the adjustable collar 15 is applied to the nozzle 10 in position, both rotatively with regard to said nozzle, and at appropriate height to limit the turning movement of the nozzles with the port 12 in open engagement, as shown in Fig. 4. A slight movement to the right, viewing Fig. 4, acts to shut off the liquid supplied to the nozzle 10 and close 7 the valve, as shown in Fig. 5. Further movement to the right of the casing 8 brings the free flowing nozzle 9 in position with its port 11 to register with the port 7 of the fixed valve member 5. It is unnecessary to have a stop to limit the turning movement of this nozzle, as the amount of liquid fiow is readily determined by the extent to which the ports 11 and 7 are brought into register, this being preferably under control of the operator, and can well be regulated by the extent of opening of the usual faucet or bib handle.

It will be appreciated that either of the nozzles 9 or 10 may be utilized as the handle or means for rotating or operating the valve. It will also be appreciated that by having the nozzle 10 of appropriate form and height to receive the filter 13, either nozzle may be swung into position over apitcher or other receptacle, both the discharge openings of the free flowing nozzle 9 and filter 13 being on the same horizontal plane, that is, of equal elevation. With the nozzle 10 in position to receive the water flow from the port 7 the sediment collecting recess and reduced flow through the valve, coupled with the gooseneck construction of the nozzle 10, causes a preliminary filtration of the water directly in the valve itself, any sediment tending to settle in the pocket caused by the wall 28. Any such sediment is, of course,

quickly flushed or swept out when the increased volume and flow is permitted through the nozzle 9, with-its port 11 opening substantially into the bottom of the recess 6 and eliminating the sediment collecting pocket;

Furthermore, my arrangement, whereby the filter is in a raised posltionafi'ording. am-

ple height or clearance underthe regular faucet nozzle so that at 131 501161 or other contamer, when posltloned under the faucet, can

receive either-filtered water or theregular free flow of-water from the faucet with full and equal clearance. afiorded by-the position of the faucet for both, is a most important feature. Thus in my invention, I'provide a plurality of nozzles, with one or more (preferably the filter-carrying nozzle) turned upwardly as a gooseneck which is a distinct novelty and which I claim herein broadly.

WVhile- I have necessarily described my present invention somewhat in detail, it will be appreciated that I may vary the size, shape and arrangement of parts within reasonably wide limits without departing from the spirit of the invention.

My invention is further described and deoperating with another nozzle to fiush said sediment collecting pocket.
