MILTON PERLMAN gm vm ATTORNEYS United States Patent 3,265,082 VALVE AND DIVERTER CONSTRUCTIGN Milton Perlman, Detroit, Mich, assignor to Nile Corporation, Royal Oak, Mich. Filed Apr. 24, 1964, Ser. No. 362,380 2 Claims. (Ci. 137119) This application, a continuation in part of my prior United States patent application, Serial No. 312,424 of September 30, 1963, relates to valves or faucets for use in outletting through a single spout, with a diverter construction incorporated therein for diversion to a secondary or spray line through a diverter tube in the spout.

It is an object of the present invention to provide a simplified valve and diverter construction characterized by the location of the diverter in the spout mouth of the valve and the incorporation of the diverter tube in the spout of the valve, such tube leading, through the valve, to a secondary line.

Such novel form of diverter construction enables selective flow through the mouth of the spout or through the secondary water line, such as a spray tube, as desired.

For an understanding of the valve and diverter construction hereof, reference should be had to the appended drawings which show a preferred embodiment.

In these drawings:

FIG. 1 is an elevation view of the valve showing the spout and the secondary water line in place.

FIG. 2 is a view in vertical cross-section of the assembled valve with the secondary water line shown diagrammatically and with a portion only of a spout and diverter tube being shown.

FIG. 3 is a large scale sectional view of the spout mouth and diverter construction therein located.

FIG. 4 is a section view on line 4-4 of FIG. 3.

FIG. 5 is an exploded view of parts at the spout mouth.

FIG. 6 is a fragmentary sectional view of a sealing element.

The primary valve The valve hereof, hereafter referred to as the primary valve, as shown best in FIG. 2, comprise (FIG. 6) a cylindrical shell or collar or sealingelement 10 surrounding a cylindrical valve body orcore 12. Vertical inlet bores not here shown (FIG. 1), adapted to be connected at their lower ends to hot and coldwater inlet lines 18 and 20, open into the dome shaped rounded convex upper end orvalve seat 22 of thebody 12 and provide inlet ports. These are not herein shown inasmuch as the inlet parts form no part of the present invention and in addition are more specifically and in full detail shown in the aforesaid application.

A third vertical bore 23, for outletting, also opens toseat 22 of the body and at its lower end opens to a transverse horizontal passage or bore 24 herein referred to as a first water outlet passage, arranged to open laterally.

Againstseat 22 ofbody 12 is a concave primary valve member 25 which is seated to be shifted or rotated for control purposes. From its upper convex surface, upwardly extends acentral stem 26 providing a hand grip.

Valve member 25 has inlet openings not herein shown and an outlet opening 27. The location of the openings in valve member 25 determines relative communication among the inlet passages and the outlet passage 24.

The foregoing parts generally are like those described in the aforesaid application.

Diverter At this point We now describe certain of the new parts of the valve disclosed herein for the first time and which Patented August 9, 1966 enable diversion of water flow as desired and as will hereafter be described.

It has previously been stated thatprimary valve body 12 has a first water outlet passage 24 opening laterally to the outside of thevalve body 12.

In addition, there is a secondwater outlet passage 70 opening laterally to the outside of thevalve body 12. In other words, there are two later-ally openingwater outlet passages 24 and 70 with the first passage 24 being above thesecond passage 70.

The valve body has not only the first vertical waterv outlet passage 23 which opens at its lower end to the lateral passage 24, but also has a second verticalwater outlet passage 71 which opens at its upper end to the secondlateral passage 70.

Betweencollar 10 andvalve body 12 are two separateannular relief passages 72 and 73, one above the other, and each communicating separately with a lateral passage as shown. Thus, a path is provided comprisingparts 23, 24 and 72; and a second path is provided comprisingparts 73, 70 and 71.

Collar 10, previously referred to as a cylindrical shell, surrounds and seals bothpassages 72 and 73.

Carried by and sealed to said collar is aspout 76 which has one end fixed to thecollar 10, with such end encompassing bothannular passages 72 and 73.

Withinspout 76 as shown best for the time being in FIG. 2 is adiverter tube 77, which opens to and seals thelower passage 73 and thus communicates with passages and 71.

In addition to the foregoing parts and adapted to be provided for use with the valve herein shown there is asecondary water line 79 connected to the secondwater outlet passsage 70 by means ofvertical passage 71. Such water line is generally provided for a spray tube or spray head 80 (FIG. 1) located at the end ofline 79.

Incorporated withinline 79 is a spray orsecondary valve 82 which is normally closed and spring loaded but which may be opened manually whenever desired as for example when it is desired to spray throughspray head 80.

In valves of this sort, particularly for kitchen sink use but for other uses as well, it is desired to incorporate a diverter which operates in such a way that normally Water flows out of the mouth 83 (FIGS. 1, 3, 5) ofspout 76 and does not flow out ofspray head 80 ofsecondary line 79, but with the parts arranged in such a way that whensecondary valve 82, which is normally closed, is manually pressed open, the flow of water is diverted to thesecondary water line 79 and sprayhead 80, with water flow fromspout mouth 83 being inhibited.

At this point therefore, there is described a diverter construction. Novel hereto is the fact that the diverter is located within the generally vertically extending and downwardly openingspout mouth 83. Normally, with valve =82 closed, water iiows out ofspout mouth 83 and there is no flow out ofspray head 80. The diverter in the spout mouth operates automatically, whenvalve 82 is opened, to shut off flow fromspout mouth 83 and to direct all flow throughspray head 80. Such diverter construction will now be described with particular ref erence to FIGS. 3-4 which show such diverter construction in enlarged scale view and in detail.

FIG. 3 shows thespout 76 disposed generally horizontally and formed with a generally vertical downwardly openingmouth 83.

FIG. 3 also showsdiverter tube 77 having a closedend 78 disposed within thespout 76 and having an orifice S4 in the lower surface of such closed end, withorifice 84 opening downwardly and located within thespout mouth 83.

Aunitary diverter element 89 has ahousing 90 also within the spout mouth. Such housing has anipple 91 inorifice 84 ofdiverter tube 77, and has its lower end seated in anadapter 92 fixed inspout mouth 83, with the lower edge of thehousing 90 being adjustably clamped in place against a flange 92a of anipple portion 93 ofadapter 92 .by a threadedaerator ring 94, there being aresilient washer 95 betweensuch ring 94 and the adapter nipple 93. The upper portion of thediverter housing 90 seats firmly against aresilient washer 96 and thus against the lower surface of thediverter tube 77, flattened for this purpose.

Inhousing 90 is located adiaphragm 101 whose outer edge is clamped in place in thehousing 90 by afixed spacer 103 and afixed support 105, so that the outer edge ofdiaphragm 101 is not movable.

The inner edge ofsuch diaphragm 101 loosely engages apiston 106 to whose upper end is integrally secured the inner edge of anannular piston plate 107 whereby the upper end of thepiston 106 is 'very considerably enlarged, considerably more than the enlargedlower end 108 of thepiston 106. Thus thepiston 106 with its somewhat enlargedlower end 108 and its greatly enlargedupper end 107 is a differential area piston, whose operation will later be described.

Mounted inhousing 90 is apiston seat 110 in the form of a conical ring whose inner annular edge defines a discharge opening 111 adapted to be closed by the lower enlargedend 108 ofpiston 106 when the latter is lifted to the dotted line position shown from the full line position shown.

In order to back up thediverter tube 77 against the thrust imparted to it by the threading up of theaerator ring 94 onto theadapter plate 92 of thespout mouth 83 and thus upwardly thrusting thediverter housing 90 against the lower surface of the diverter tube v77, the latter is so formed that itsend 78 backs up against the upper surface of thespout mouth 83 so as to be backed up by it.

Slots 112 in thehousing wall 90 betweenspacer 103 andpiston seat 110 communicate the interior of thehousing 90 with the spout mouth to permit water flow from the spout into the interior of thehousing 90 throughslots 112 and thus selectively down through the opening 11]. inpiston seat 110 and out through theaerator ring 94 for conventional flow, or alternatively up throughhousing nipple 91 and intodiverter tube 77 for diverted flow to thesecondary line 79 whensecondary valve 82 is opened.

The diverter operation is as follows:

Withsecondary valve 82 closed as is normal,piston 106 is in its full line lowermost position due to the effect of gravity and there is no force to counteract this efiect. Accordingly discharge opening 111 inpiston seat 110 is open and water flows throughspout mouth 83, throughslots 112 ofdiverter housing 90, and out through the opening 111 inpiston seat 110 and out downwardly throughaerator ring 94. No water flows up through thehousing 90,nipple 91 and intodiverter tube 77, and thus no Water flows in thesecondary line 71.

Whenvalve 82 however is opened,secondary line 79 anddiverter tube 77 are opened, andpiston 106 is lifted to close the opening 111 inpiston seat 110 by the differential area effect, responsive to the fact that theupper end 107 of thepiston 106 is greater in area than thelower end 108. With the piston so lifted to close the opening 111 inpiston seat 110, the flow of water entering thehousing 90 throughslots 112 is upward inhousing 90, between the inner edge ofdiaphragm 101 andpiston 106, exiting throughnipple 91 and intodiverter tube 77 and out throughsecondary line 79 to spray head and at the same time is diverted so as no longer to flow down and out of the spout mouth throughaerator shell 94.

Now having described the valve with diverter construction herein disclosed, reference should be had to the claims which follow.

I claim:

1. In spout and diverter construction;

a discharge or outlet spout extending generally horizontally and having a generally vertical spout mouth with a downwardly directed discharge opening;

a diverter tube in said spout having a closed end in the spout mouth with a lower surface orifice in the spout mouth above the discharge opening;

a secondary valve normally blocking said diverter tube and openable as desired to permit flow in said tube;

a diverter in said spout mouth below said orifice;

said diverter being a unitary diverter element comprising a housing having a bottom valve opening and containing a vertically movable differential area piston valve which moves up to seal the valve opening from below and down to expose said valve opening;

said piston, when down, as is normal, permitting full flow through said valve opening and discharge opening and no flow into the diverter tube orifice and adapted to be moved upwardly automatically on the opening of said valve by water pressure to close said valve opening and said discharge opening to inhibit flow through said discharge opening and to permit full flow into the diverter tube orifice;

said diverter, including its housing and valve as a unitary diverter element, being insertable as a unit into the spout mouth upwardly through its discharge openand a ring threaded onto said spout mouth at the discharge opening to retain said unitary diverter ele ment in said discharge opening.

2. In a construction according to claim 1;

the closed end of said diverter tube upwardly abutting the upper wall of said spout mouth and thus providing an abutment against which the diverter element is thrust by adjustment of said ring on said spout mouth.
