To all whom it may concern.'

Be it known that I, Orvis W. VALLIER, a citizen of the United States, residing at Watertown, in the county of Jefferson and State of New York, have invented certain new and useful Improvements in `Tater- Mixing Valves, of which the following is a specification.

This invention relates to improvements in water dispensing valves, designed for use in connection with baths, sinks, lavatories, and the like, and the invention relates particularly to a single valve by which, cold,

warm and hot water maiy be dispensed by 1 the' use of a single cont t The object of the invention is to provide a novel valve body including integral cold and hot water receiving arms, -which are adapted tobe constantly charged with the water pressure, and which communicatedirectly vwith the interior vof the valveV body. A further object is to provide a valve which is rotatably disposed Ain the body between the said arms, the said valve beingformed with a common mixing-chamber, and with prts that communicate with said chamber and are adapted to be moved into registry with, said water receiving arms, the said valve being controlled b a stem,and a handle carried thereby.r to provide novel means-for resiliently holding the valve' seated insaid bodyand for,

maintaining the valve and related parts* truly concentric t'o said body. And a further object vis to provide .adjustable means for 'Y limiting the rotary movements of the valve.

Y water vsupply pi I attain these objects by the means set forth in the detailedfdescriptionwhich follows and as illustrated by the accompanying 'drawing in which-fl 'i Figure 1 isa top plan view of the com-V plete mxing-valve,;lshowing 'ot and cold and the pro ve op-v erations of the" andle.

Thevalve 7 is (provided with a circular'radial port C, an valsowith an' elongated radial port H, both of Vsaidports communicating with the mixing-chamber 7. The lower end of stem 8 is perforated diametrically and is fitted with a' pin 8*, which prevents the separation of thestemandvalve', when thel parts are assembled for.work.. 'The stem may be withdrawn from thevalve 7, by rotating said part until the pin 8.* registers'with.- similar radial wa s 7 which are formed at the opposite sides of the bore as shown by vfull-mm1 dotted lines in Fig. 1o. The stem s is held in its' operative position, shown in Fig. 2, against rotation independently ofv the valve 7, by means of a stud 8" carried 3 by -the enlargement 8', which is arranged` to engage a radial groove 7x formed 'in-the mar- 'nof the socket `7 (see Figs. 8 and 10d.

he valve is driven by the stem 8, by means of arelatively lar metrically. throng Figs. 2 and 8), and whose 4ends engage an pm 10, which passes diaupwardlyfacing diametric groove 7y of the valve body., The in -10 is usually insertedater the stem has en applied to the valve .body,'5as shown in Fig.-2, at which time they 'pin 8@ is positioned out of registry .with the ways 7?. enthe stem andvalve are in the operative position shown in Fig..2, the

well as the free. -rotation of the stem and -Fig. 4. When4 the handle -is in the latter position the valve 7 is closed, as best seen 1n Fig. 4. Upon the -fian e 12* of the nut .is mounted a convexwas er.14, which is bored out to loosely receive the stem 8. This washer 4is split, as shown in Figs. 2 and 9,

for rendering it flexible, in a. well-known.

manner. Above the washer 14 is disposed a member A15, having adertion 15 that screws into vthe top end o ,the body 2', and above said threaded ortion said member is formed 'with `'an annu ar flange 15", which is surmounted by a hexagon rtion 15", for use of a wrench. The mem er 15 is employed .for effecting the operative seating .of the valve 7, when the assembling of the device takes place, and the said a justment need notI thereafter be disturbed unless the valve -or its seat 7" becomes worn and .leakage results;v

When the valve 7 'is rotated in either direction for dispensing the water the stem 8, owin to the stationary nature of the nut 12, 1s moved axially to whatever extent ma be required,- for effecting the full right of the' .handle 9, as indicated is is accomplished-by reason an left swing in Fig. 1. T of the looseness of the stem, as explained. l'lien the valve 7 and its stem 8 yare con-` structed, the depth of the socket 7, as well as the location of the enlargement 8 of the. stern, are calculated with 'suicient accaracy to determine the properrange or distance the handle should be moved towards the ri ht, for example, for dispensin first.

This swinging of the handle clockwise (because of the right-handy -threads 8) moves the stem 8. downwardl until the enlargement'S makes contact wit the bottom of the socket7", This stops the endwise .and rotary movement of the stem and also sto the valve, with the ports C andvH close as shown in Fig. 4. The tension exerted by the washer 14, holds'the valve 7 in its ta. red seat, `with suiicient force for'preventln leakage of the water,

-which hasuznrma pressure usually of 60 v to80 pounds, while the valve is in the idlecounter-clockwise to. the lclosed lo cold water, the operator simply swings theand at 9 in Fig. 1 the stem is moved axiall in the opposite direction by the threa .s 8, the distance allowed by the pin 8, which effects the positive Stoppa e of the stems rotation by its contact wit full lines in Fig. 7, the valve owing to its 'relatively loose connection with the stem 8, and by the accurate adjustment o f member 15 operates without any appreciable rinding or wearing contact with the seat. y this construction and arrangement of the parts the valve, after once being suitably ground and fitted to the seat may be operated for years without requiring redressing or grinding. Furthermore, it will be readily understood that my improved valve 7 needs no packing of any kind thereby eliminating waste of water, annoyance and expense. The washer 14 is arranged vto engage the lian e of the nutl 12 in a manner to prevent wob ling of the nut,l as well as the stem 8 and other parts, which might tend to cant the valve, and produce leakage or uneven wearing of the frictionally joined parts. The top end of thebody 2 is preferably closed by a screw cap 16, which engages the external threads of the body, the

`said cap serving to support and guide the stem 8. In order to prevent possible leakage around the stem, in case water should well-np in the body 2', the underside of the cap is provided with a short counterbored hub 16', which is received in a corresponding socket formed in the hexagon portion of the member 15, and in this socket is disposed a relatively thick greasy packing 17. When the cap and member 15 are finally'` adjusted and secured in place, as shown in packing 17 will last for an indefinite .time without requiring renewin The handle 9 is detachably secured to t e threaded upper end of the stem, by means of a nut 9'.,

After the mixing-valve is fully assembled,

as shown in Fig. 2, its ,operation is quite simple: Assuming that the handle 9 is in position 9, shown in Figs. 1 and 4, to draw handle counter-clockwise to position 9* of Fig. 1. This brings the port C of the valve into registry with the cold water duct 3b for dispensing only cold water (see Fig. 5). To drawwarm water, the operator moves the handle in the same direction, to the full line position 9 of Fig. 1. This moves the valve 7 to the position shown in Fig. 6, wherein both orts C- and H are partial] in registry wit the ducts 3b-4" which e feots the mixing of the cold and hot water, for producing a tepid supply. To draw 'only hot water, the handle 8 is again swung counter-clockwise to position 9d of Fig. 1.

This moves the port C entirely out of registry with the duct 3", and moves the port H into full registry with the port 4" (see full lines in Fig. 7.). The valve 7 may then be closed for stopping the discharge of the water, by simply moving the handle a short dista-nce in the same direction, as to position 9e of Fig. 1. This shifts the port H entirely out of registry with the duct 4",

asfshown by the dotted lines in Fig. 7. After the hot water requirements are satisfied, the operator may swin the handle 8 clockwise to position 9a of ig. 1. in order that the valvev may be ready for dispensing cold water at the subsequent operation.
