ing the supply of hot and cold water, and in a double acting valve wit-ha device adapted for use in special places where an extremely delicate or accurate degree of-temperature must be continuously ha 4 In the drawings, wherein like reference characters denote correspondingfp'arts in the several views, Figure 1 is a central vertical sectional view of the device, the c'om ound or double acting valve being at its owest point and open to the coldv water. Fi 2 1. Fig. 3 is a center sectional view of the valve body, the two upper char'nbers being broken away, the compound va've and two checkvalves being shown in elevation and Fig-,4 is an end elevation of Fig. 3 "artly shown in center section on iine4-4 0% Fig. 2. Arrows indicate direction of the ,water.

The valve body,'1, is composed of a casting cor'ed out in such a ina'n'ne'r as to provide an inlet, 2, for cold water a seating, 3, for aheck valve, 4., an upper e amber, 5, an inlet for the hotwate'r, '6, afs'eating, 7 for. a check valve, 8 a lower c aftnber, 9-, an inner c mber, 10, having an outlet 11': this inner chamber also has two ports in which tli'ebon'i pound valve slides, t-he upper 13 is the 'cold water inlet and the lower port, 14, is the hot water inlet. The compound valve, 15,

.Jpiece,

has two crown disks, 15 15 respectively,

Ian which the fingers, 15-, m reverse and ob- ,verse, {as shown .in Fig. 3, the disks 'andlingers being neatly grolmd into their respecve ports to make a close, sliding fit. The integral valve stem extends above and below said valves, the upper part, 16, connecting with "a rtfbber diaphragm, 17, and the lower part, 18, eonnecting with another Eliahragm, 19, as shown, Thediaphragih, 17, s held in place by the flange of a connecting 20,- and by the u I I21, on the upper cham er, by'ineans of a nut, 22, or in any preferred manner, while the Sdiaphra 19, is held in place between the lower e ge of the neck, 23-, on the lower j chamber and a spring case, 24, which is screwed 'on said neck.

a. 24 is an air hole. A helical spring, 25,

presses upwardly against a flanged nut, 26, which is screwed on the lower valve stem, 18, to hold the diaphragm in position: a screw plug 27-, having a square head '27 is adjusta-bly placed in said spring 'case.

The "connecting piece, 20, screws into ,a convex body 28 havinlgea flange, 28 which supports the air cham r, 29, and the water cylinder or case, 30, for conve ing the water upwardly and out through t "e outlet, 30 said cylinder being provided with an in- .teg'i'al annular flange, 302 at its lower d.

and an inlet, 30, for the The air chamber, '29, is made of thin metal,

preferablggbr'ass or copper, a series of tubes,

chamber. A series of oles are drilled through said flange to aline with holes in the flanges, 30 and 28 into which screws, 32, "are inserted for holding and clamping the said air ichamber, the water cylinder and the rubber 'dia hragm,'33 together. Anexitension, 16 o the upper valve stem, 16 is {threaded for the reception of a flanged not, 334, the diaphrag 17 being centrally held 1n centrally held between the said two parts,

Two plug caps, 38, 39 respectively act as guides for the stems, 4 and 8 respectively of the check valves, and also afiord a means for inserting or removing the check valves from the valve body. A curved tube, 40, screwed into the outlet, 11, of the inner chamber, 10, conveys the Water from the .valve body, 1, upwardly 'into the water cylwardly against the spring 25, this in turn pressing upwardly against the lower nut on the valve stem whereby the compound valve is operated,'said valve opening and closing, one or the other of the hot or cold water ports, and when the desired temperature of the water has been reachedat the outlet, that degree will be maintained automatically and instantly in the following manner: If the hot water should become cooler, the temperature of the mixed water, passing upwardly through the narrow, annular space between the cylinder and air chamber and through the lateral tubes in the air chamber, will be proportionately lowered, the confined air within the air chamber will contract and with the aid of the spring, 25, the compound valve will be pushed upward whereby the cold water is closed off and an excess of hot water is turned on in exact proportion to the difference in the temperature. If the hot water should be come hotter than the device was set for, the reverse operation would take place; that is, the mixed water would rise in temperature whereby the confined air in the air chamber is expanded, the diaphragm, 33,

will be depressed by the valve stem against the action of the spring, 25, the hot water be shut off and an increased quantity of cold water be turned on until the balance between the compressed air and the compressed spring was reached. This action is so rapid, owing to the constructionof the device, that a few degrees variation of the waterat the outlet will immediately aflect the adjustment or balance which is automatically controlled by the compound valve sliding in the inner chamber, 10, as described.

Briefly stated, the spring, 25, raises the compound valve and presses upwardly against the confined air in theair chamber, and when said air is caused to expand, it presses the valve downwardly against th spring, 25.

What I claim is- 1. In an equalizing valve for water, a valve body having separate inlets for hot and cold water, respectively, an inner chamber communicating with the said inlets, a double actmg valve controlling inlet ports in said inner chamber, a superim osed water cylinder connected to said valve ody and in communication with said inner chamber, an air chamber positioned in said water 0 linder, open transverse tubes through sai air chamber, a diaphragm closing one end of said air chamber, mechanical means for pressing said valve in an upward direction and a valve stem upon said valve having one end thereof engaglng said diaphragm.

2. In an equalizing valve for hot and cold water, a double. acting valve, verticall mounted in an inner chamber through which the hot and the cold water passes, an adjustable spring pressing u wardly against the valve stem of said double acting valve adapted for positioning the valve for a delivery of water at a predetermined temperature, a water cylinder having an inletat its base and an outlet at its apex, a pi e coinmunicating between said inner chamber-and inlet, said water cylinder inclosing an air chamber, a flexible diaphragm closing one end of said air chamber, transverse water pipes through said chamber, and means centrally mounted in said diaphragm for press-- ing the valve stem of said double acting valve downwardly for closing off the hot water when the confined air in said air chamber is expanded.

3. In a valve device, a valve casing having an inner chamber, hot and cold water inlet ehambers at opposite sides thereof and said inner chamber communicating at its bottom and top respectivel with said hot and cold water inlet cham er, a vertically movable double acting valve in said inner chamber, oppositelyextending stems upon said valve, an adjustable spring contacting the free end of said lower stem adapted for predeterminedly positioning the valve, a water cylinder mounted upon said casing with a bottom inlet and a top outlet, a pipe.

connecting said inlet and inner chamber, an air container within said cylinder, transverse water pipes through said container, a diaphragm closing the bottom of said container and the upper stem engaging said diaphragm and adapted for movement upon a change in temperature of the air in said container. I

4. In a valve device, a valve casing having an inner chamber, hot and cold water inlet chambers at opposite sides thereof, and said inner chamber communicating at its bottom and top respectively with said hot and cold water inlet chambers, a vertically movable doubleacting valve in said inner chamber, oppositely extending stems upon said valve, an adjustable spring contacting the free end of said lower stem adapted for predeterminedly positioning the valve, said casing having a terminal bottom chamher, an adjusting plug closing the bottom of said last named chamber and a diaphragm closing the top thereof and positioning said spring therebetween, said casing also having a top chamber, a diaphragm closing said top chamber and secured substantially centrally to said upper stem, said casing provided with air ports communicating with said top and bottom chambers, a water cylinder mounted upon said casing, a bottom inletand a top outlet for said Water cylinder, a pipe connecting said inlet and inner chamber, an air container wit-hm said cylinder, transverse water pipes through said container, a diaphragm closing the bottom of said container 15 and the upper stem engaging said d ia phragm and adapted for movement upon a change in temperature of the air in said. container.
