s claims. (ci. zas-12) l This invention relates to a thermostatic watercontrol for bath tubs, kitchen sinks, wash basins,

showers, etc.

An object of the invention is the provisionfof. simple and eillc'lent means for blending togetherv hot and cold water when desired, or when the operator desires he can easily adjust the mechanism for discharging only cold water.

Another object of the invention is the construction of a vmechanism of the character described, which can be set into a wall of a room where it will be hidden from view and only the indicator disc or plate with the pointer exposed to view, thereby causing the mechanism to -be attractive in appearance. i

A further object of the invention is the construction of a novel and eilicient valve whereby the flow of hot water or cold water, or the blending of the two, can be admirably controlled.

With the foregoing and other objects in view, my invention comprises certaind novel constructions,.combinations, and arrangements of parts as will be hereinafter fully described, illustrated in the accompanying drawing, and more particularly pointed out in the appended claims.

In the drawing:

Figure 1 is a view partly in elevation and partly in longitudinal section of a mechanism constructed in accordance with the present invention, and showing said mechanism applied within a wall of a building. -y

Figure 6 is an enlarged transverse sectional view of one of the valve sleeves and a portion of the rotary valve, while Figure 7 is a similar view of the other valve sleeve and the rotary valve therein.

Figure 8 is an enlarged elevated view indicator disc, and the pointer.

Figure 9 is an enlarged fragmentary view of a valve sleeve and the valve casing, showing the set'screw for holding these Sether.

'of the Referring to the drawing in which I have shown I the preferred embodiment of my invention, I designates a valve casing of a cylindrical type, in

parts securely tothe two ends of which are screwed valve sleeves 2 and 3, Fig. 4. Each valve sleeve comprises a hub portion 4 on the inner end of which is the reduced cylindrical extension 5. Threaded into valve sleeve 2 is thehot water pipe 8, and threaded into the valve sleeve 3 is the cold water pipe 1. A cylindrical rotary valve 8 is mounted within the valve sleeves 2 and 3. 'I'his rotary valve has a central partition 9, and on its outside it is provided with an outwardly extending finger I9; finger I II moves or swings between the contiguous inner ends of the valve sleeves 2 and 3. By means of plug II, Fig. 2, access is obtained to the interior of valve casing I, whereby the operator may connect the link I2 to the nger I0, or he may clean out the valve casing I, as he desires. Detachably securedV to the top of valve casing I is a housing I3; this housing has guide grooves I4 formed on its inner face; these grooves I4 are `arranged in vertical position and are in alignment, whereby the ribs I5 are received, and thereby lpermitting the thermostat frame I6 to have a vertical sliding movement within housing I3. Within frame I5 is a common type thermostat I1; thermostat I1 -has a depending stem I9, which stem is pivotally connected to the upper end of link I2, whereas the lower end of link I2 is pivotally connected to said finger I0. Integral with and extending upwardly from housing I3 is a globe portion I9. The upper portion Yof the globe portion I9 is threaded at 20, to receive any suitable piping as indicated by dotted lines 2|, Fig. l, which piping is connected to a spigot or faucet 22.

A shaft 23 (Fig. 2) extends through tube 24, sleeve 25, and its inner end is positioned in the globe portion I9. A-link 28 is in the globe portion I9 and said link is connected atits lower end in a pivotal manner to the pair of lugs 21 that extends upward from the vtop of frame I6. A suitable connection 28 pivotally fastens the upper end ofy link 25 to rotary shaft 23. The sleeve 25 is threaded at its inner end into portion 29 of the globe I9, and the tube 24 is threaded on the outer closed end of sleeve 25. A set screw 30 serves to securely retain tube24 on sleeve 25. On the 4outer end of tube 24 is an integral indicating disc 3i; disc 3| is preferably placed against a wall 32, with the rest of the apparatus either built in the wall or behind the same, whereby only the disc 3| and pointer 33 show in the room, whereby an excellent appearance is produced. The pointer 33 is securely fastened to the ll designations "Hot," "Medium, and "Cold" for ltile purpose hereinafter described.

Thevalve sleeves 2 and I are securely fastened togetherby set screws 24 (Fig. 9).

The valve sleeve 2 is provided with a plurality of vparallel transversely positioned elongated slots 3l.V through which hot water is adapted to pass. [The right hand portion of rotary valve l is provided with ports or openings 2l, which are adapted to register with said elongated openings 3l. The valve sleeve 2 is provided with aligned ports oropenings l1 through which cold water is adapted to pass. The left hand portion o! rotary valve l is provided with a plurality of aligned ports or openings 3l that are adapted to register with openings l1, i'or allowing cold water to pass from pipe 1. into the valve casing I and in due course be discharged through the spigot 22.

When the mechanism is in they position shown f in Figures 1 and 2, theonly escape `i'or the water when the spigot or faucet 22 is turned on is through openings 3B and 3B. Then-as the water passes up and around the thermostat i1, said thermostat will expand and lower the4 opening 2Q to the bottom of the elongated or oblong openings 3l, which is the limit of expansion for the thermostat, and since openings Il and 38 remain closed, hot water is all that comes from the faucet 22. 1

Then when the pointer 22 is set in the posi- -tion oi' "medium," the thermostat i'l is lowered within the housing Il., placing the openings -21 and 38 tangent with each other and the openings 28 are lowered to the bottom of openings Il.'

This again'allows the hot water to enter iirst and as it passes over the thermostat, openings 31 and Il start opening, and openings I8 and 38 begin closing, which gives a medium or any tempera-V ture water desired between hot and cold.

When the pointer 33 is set to indicate "co1 openings or ports 31 and 2l are entirely open, and openings 35 and 26 are entirely closed. Therefore, since cold water has no effect upon a thermostat, the sleeve valve 8 remains in this position and cold water is al1 that comes from the faucet 22.

While I have described the preferred embodiment of my invention and illustrated the same in the accompanying drawing, certain minor changes or alterations may appear to one skilled in the art to which this invention relates during the extensive manufacture of the same, and I, therefore, reserve the right to make such alterations or changes as shall fairly fall within the scope ofthe appended claims.

What I claim is: v

1. In4 a mechanism of the class described, the combination of a.valve casing, separate sleeves in said valve casing and extending inwardly from its ends, one of said sleeves being provided with a plurality of hot water openings at its top ,and the other sleeve being providedlwith a plurality of cold water openings on its side. a rotary valve within said sleeves provided with sets oi' hot and cold water openings being adapted to register with the corresponding openings of said sleeves at predetermined times, a thermostat housing on said valve casing. a thermostat frame slidably mounted within said housing, a thermostat within said frame, means connecting said thermostat to said rotary valve only between the in ner ends of said sleeves. indicating means including a disc with diiferent temperature markings thereon and a pointer cooperating with said dac'. namens connecting ma pointer to ma slidable thermostat frame, 'whereby when said pointer is manually adjusted with reference to the temperature markings on said disc said rotary valve will -be vrotatedto bring like openings on said valve and sleeves in registering position to control the'l temperature of water flowing through the valve casing.
