Application February 1, 1940, Serial No. 316,804

2 Claims.

This invention relates to improvements in' sink llxtures, and has to do with combination fixtures in which valves for hot and cold water are in.

corporated to control the flow of either one or a mixture of both from a common exit. `Fixtures of this kind commonly employ a swing spoutl disposed between the two valves through which the water is delivered. It is also known to provide in addition to the swing spout a hose connection with a spraynozzle on the extremity thereof through which water may be delivered if desired and to provide a diverter valve by means of which the operator may cause water to iiow alternatively either to the spout or to the spray nozzle. The present invention is concerned with an improved means for accomplishing the latter purpose.

One of the objects of the invention is the provision -of a screw valve cooperating with either of two opposed valve seats, both of which are immovably positioned in the valve body.

Another object of the invention is the provision in valve apparatus of the character stated of a diverter valve which shall be'positive and certain in action and which shall have two positions into either one of which it may be setwithout regard to the position of the swing spout.

Other objects and features vof novelty will appear as I proceed with the description of that embodiment of the invention'which, for the purposes 'of the present application, I have illustrated in the accompanying drawing, in which:

Fig. 1 is a plan view of a sink fixture embodying the invention. v

v, Fig. 2 is a vertical section taken-substantially on the line 21-2 of Fig. l.

Figs. 3 and 4 are horizontal detail sectional views taken substantially on the lines 3-3 and 4--4 respectively of Fig. 2.

In the drawing, I0 represents the ledge of a metal sink directly behind the sink cavity. A Suitable openings II, I2 4and I3 are provided in this ledge for the reception of the upstanding parts of a valve body located otherwise beneath the ledge. These upstanding parts comprise threaded sleeves I4 at each end of the-fixture,- n'only of which is illustrated, and a central s1, eve I5. The fixture is clamped to the ledge II) by means of nuts I6 threaded on the two sleeves I4 and working through washers I1 to grip the ledge against --radial flanges I8 on the iixture `below the ledge.

Two valve stems I9 and 20 with handles 2I .and 22 at their upper ends are provided for turning on or off the hot and cold water respectively. These valves may be identical in construction. and

4I) arranged as illustrated at theI left side of Fig. 2, may comprise a threaded collar 23 turning in av correspondingly threaded wall 24 and having a valve piece 25 arranged to engage a removable and replaceable valve seat member 26. In order tol present a Ysmooth exterior these control valves comprise

metal escutcheons

21 and 28 which are preferably plated and polished and are held in position by clamping

nuts

29 and 30.

Hot and cold water, represented by the'arrows A and B, may enter the valve body when the control valves at thepends of the iixture are open and will then flow inwardly toward and into the central sleeve member I5. Positioned centrally within the latter member there is a tubular casting 3| with a valve seat 32 at its upper end. This casting is threadably mounted in the valve body at 33 and has a downwardly projecting nipple 34 for receiving a flexible rubber hose 35 which is clamped to the nipple by a hollow nut 36. While not herein illustrated, it is to be understood that the hose 35 may extend upwardly through. an opening in the ledge III and may carry on its opposite extremity a spray nozzle for rinsing dishes, fruit, and the like.

The valve body above the sleeve member I has an upwardly continuing portion 31 roughly cylindrical in shape which is provided with'a @assur-D I UUT 1 4 1941 downwardly facing valve seat 38 that is opposed j to and spaced from valve seat 32. The body member 31 is preferably mounted in the sleeve member I5 byl a threaded joint as shown and is hollow to provide a path for water to ow upwardly from the valve seat 38. Intermediate itsL length this body member has a spider or bridge 33 in which are formed a series of perforations in a circle surrounding a central threaded opening in which is mounted a threaded vportion 4I of a valve stem 42. This valve stem has a reduced lower end upon which is mounted Aa metal washer 43 with peripheral flanges extending both upwardly and downwardly. Gaskets 44 and 45 are positioned in the cavities formed by these flanges," the upper gasket being adapted to engage valve seat 38 and the lower gasket being adapted to engage valve seat 32. The lower extremity of the stem 42 is threaded and has a attened side indicated at 46, Fig. 3, in order to receive a D-washer 41. A nut 48 threaded onto the stern works through D-washer 41 to clamp the washer 43 with its gaskets 44 and 45 against the shoulder atvthe upper end of the reduced portion of the stem, the D-washer acting as a lock to prevent accidental loosening of the mounting for the gaskets.v Obviously. when the stem is threaded downwardly gasket 45 engages seat 32 and provides a passage for water upwardly, while threading the stem upwardly unseats gasket 45 and causes gasket 44 to engage seat 88, thereby providing a passage for water downwardly through casting 3|. On this central part of the xture an escutcheon 49 similar to the

escutcheons

21 and 28 is employed.

50 is a swing spout which at its rear end has a downwardly projecting hollow trunnion 5| that extends into body member 3 1 and has a bore of larger diameter than the external diameter of the stem 42. Suitable means are provided to rotatably support the trunnion 5| within the body member 31 which, in the illustrated embodiment, comprises a split spring ring 52 that is set within an annular groove formed in the trunnion, the ring 52 resting upon an annular shoulder 53 of the body member. Above the ring there is a suitable packing 54 which is heldin place by a gland nut 55. A short tubular extension 56 is provided on the upper side of the spout 50 in alignment with the trunnion 5|, through which the stem 42 protrudes with clearance. This ex tension is threaded externally to receive a gland nut 51 covering packing 58.

A hand wheel 59, or other form of hand grip, is secured to the upper end of stem 42 for convenience in turning the latter. The threads`4| are relatively coarse and prefer'eably of such pitch that a movement of the stem is sumcient to actuate the diverter valve from one operative position to the other. In order that the operator may know how the valve is set at any given time the handle 59 may be marked to provide that in- `formation, as for example by the letters H, meaning hose, and S, meaning spout. When the H is forward, as in Fig. 1, the Valve is set to cause ow of water throughl the hose. When the handle 59 is turned from that position clockwise through 180 however the letter S will be in front, which will indicate that the valve is set to cause flow of water through the spout.

It will be observed that both of the

valve seats

32 and 38 are portions of the valve body and are therefore fixed in position at all times. Also, the operation of the valve by screw action provides positive engagement of the valve with either one of its seats, eliminating any leakage of water from the outlet not then in use and serving to hold the stem against rotation when the spout 50 is swung from one position to the other.

Having thus described my invention, I claim:

1. In a combination xture, a central upright valve body having therein opposed spaced valve seats through which water may flow upwardly or downwardly, a swing spout mountedin the upper end of s aid valve body, a valve stem extending through said spout concentric with the axisv around which the spout turns and threadably mounted in the valve body below said spout, a double valve piece on the stem for engagement with one or the other of said seats alternately, and a handle at the upper end of said stem above said spout operative through a predetermined angle regardless of the angular position of the spout for moving the valve from one operative position to the other.

2. In a combination xture, a yhorizontal conduit, a valve at each end of said conduit, a sleeve member extending upwardly from the middle of said conduit, a tubular casting extending upwardly from said conduit into said sleeve member and having a projecting lower end carrying a nipple for attachment to a flexible hose, a valve seat at the top of said casting, a body member removably secured to said sleeve member and extending upwardly therefrom, a downwardly facing seat in said body member, a diverter valve stem in said body member carrying a double valve piece adapted to cooperate alternatively with either of said seats, a swing spout oscillatably mounted in the upper end of said body member concentrically with said stem, and a handle for the stem above said swing spout whereby the diverter valve mechanism is located entirely above the said horizontal conduit for accessibility in servicing.
