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 sealing element 10 surrounding a cylindrical valve body or core 12. Vertical inlet bores not here shown (FIG. 1), adapted to be connected at their lower ends to hot and cold water inlet lines 18 and 20, open into the dome shaped rounded convex upper end or valve seat 22 of the body 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 to seat 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.

Against seat 22 of body 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 a central 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 that primary valve body 12 has a first water outlet passage 24 opening laterally to the outside of the valve body 12.

In addition, there is a second water outlet passage 70 opening laterally to the outside of the valve body 12. In other words, there are two later-ally opening water outlet passages 24 and 70 with the first passage 24 being above the second 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 vertical water outlet passage 71 which opens at its upper end to the second lateral passage 70.

Between collar 10 and valve body 12 are two separate

annular relief passages

72 and 73, one above the other, and each communicating separately with a lateral passage as shown. Thus, a path is provided comprising parts 23, 24 and 72; and a second path is provided comprising

parts

73, 70 and 71.

Collar 10, previously referred to as a cylindrical shell, surrounds and seals both

passages

72 and 73.

Carried by and sealed to said collar is a spout 76 which has one end fixed to the collar 10, with such end encompassing both

annular passages

72 and 73.

Within spout 76 as shown best for the time being in FIG. 2 is a diverter tube 77, which opens to and seals the lower 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 a secondary water line 79 connected to the second water outlet passsage 70 by means of vertical passage 71. Such water line is generally provided for a spray tube or spray head 80 (FIG. 1) located at the end of line 79.

Incorporated within line 79 is a spray or secondary 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 through spray 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) of spout 76 and does not flow out of spray head 80 of secondary line 79, but with the parts arranged in such a way that when secondary valve 82, which is normally closed, is manually pressed open, the flow of water is diverted to the secondary water line 79 and spray head 80, with water flow from spout 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 opening spout mouth 83. Normally, with valve =82 closed, water iiows out of spout mouth 83 and there is no flow out of spray head 80. The diverter in the spout mouth operates automatically, when valve 82 is opened, to shut off flow from spout mouth 83 and to direct all flow through spray 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 the spout 76 disposed generally horizontally and formed with a generally vertical downwardly opening mouth 83.

FIG. 3 also shows diverter tube 77 having a closed end 78 disposed within the spout 76 and having an orifice S4 in the lower surface of such closed end, with orifice 84 opening downwardly and located within the spout mouth 83.

A unitary diverter element 89 has a housing 90 also within the spout mouth. Such housing has a nipple 91 in orifice 84 of diverter tube 77, and has its lower end seated in an adapter 92 fixed in spout mouth 83, with the lower edge of the housing 90 being adjustably clamped in place against a flange 92a of a nipple portion 93 of adapter 92 .by a threaded aerator ring 94, there being a resilient washer 95 between such ring 94 and the adapter nipple 93. The upper portion of the diverter housing 90 seats firmly against a resilient washer 96 and thus against the lower surface of the diverter tube 77, flattened for this purpose.

In housing 90 is located a diaphragm 101 whose outer edge is clamped in place in the housing 90 by a fixed spacer 103 and a fixed support 105, so that the outer edge of diaphragm 101 is not movable.

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

Mounted in housing 90 is a piston 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 enlarged end 108 of piston 106 when the latter is lifted to the dotted line position shown from the full line position shown.

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

Slots 112 in the housing wall 90 between spacer 103 and piston seat 110 communicate the interior of the housing 90 with the spout mouth to permit water flow from the spout into the interior of the housing 90 through slots 112 and thus selectively down through the opening 11]. in piston seat 110 and out through the aerator ring 94 for conventional flow, or alternatively up through housing nipple 91 and into diverter tube 77 for diverted flow to the secondary line 79 when secondary valve 82 is opened.

The diverter operation is as follows:

With secondary 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 in piston seat 110 is open and water flows through spout mouth 83, through slots 112 of diverter housing 90, and out through the opening 111 in piston seat 110 and out downwardly through aerator ring 94. No water flows up through the housing 90, nipple 91 and into diverter tube 77, and thus no Water flows in the secondary line 71.

When valve 82 however is opened, secondary line 79 and diverter tube 77 are opened, and piston 106 is lifted to close the opening 111 in piston seat 110 by the differential area effect, responsive to the fact that the upper end 107 of the piston 106 is greater in area than the lower end 108. With the piston so lifted to close the opening 111 in piston seat 110, the flow of water entering the housing 90 through slots 112 is upward in housing 90, between the inner edge of diaphragm 101 and piston 106, exiting through nipple 91 and into diverter tube 77 and out through secondary 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 through aerator 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.
