vA further object of the invention is to provide a valve structure of the character mentioned equipped with additional means whereby a spray head may be easily attached thereto and readily operated to discharge liquid at the desired temperature.

A still further object of the invention is to provide a valve structure capable of being easily and minutely operated to determine the temperature of the liquid within the valve las well as the pressure of now, with additional means to determine the rate of low or pressure in the discharge spout.

A still further `object of the invention is to provide a valve structure embodying means whereby the rate of dow as well as the temperature of vthe mixture within the valve may be regulated and set, with additional means Ito determine the rate or pressure of ow from the spout at the temperature already determined by the initial regulating means.

A still further and particular object of the invention is to provide a unitary valve of the character generally set forth which is of extremely simple construction, which involves but few simple and readily assembled parts, which has its several parts so constructed and arranged las to insure proper operation at all times, and to minimize the opportunity for wear, breakage or derangeme'nt, which is positive in all of its several action-s, and which prove highly effective and eicient in practice.

4With the foregoing objects in view, together with others which Will appear as the description proceeds, the inven- -tion resides in the novel construction, combination and arrangement of parts, all as will be described more fully hereinafter, illustrated in the drawing, and particularly pointed out in the claims.

The faucet of my invention may be used in connection with wash stands or other bathroom fixtures as well as with basins, kitchen sink-s or other apparatus, with or without -a spray head connection.

ln carrying out the invention, I provide an elongated housing of substantially hollow cylindrical form indicated at 10, the outer surface `of `which is provided with threads as shown to accommodate lower and upper clamping nuts 11 and 12, whereby the housing may be rigidly secured within an opening 13 in la wash basin or wash stand portion indicated at l14. This housing is of tubular formation, the inner wall of which is of reduced diameter as at 15 to provide a concentric mixing chamber 16 with an abrupt shoulder 17 at its upper end Where it joins or communicates with the interior of the housing portion 10. The mixing chamber 16 is dened at its lower end by an -annular shoulder 18 which provides a valve seat determining the upper end of a liquid supply inlet charnber 19 concentric with the housing and yof less diameter than the mixing chamber 16. The lower end of the inlet chamber is closed by the screw plug 20. The inlet chamber communicates with hot and cold ports 21-22 within the nipples 23 projecting laterally in diametrically opposite directions from the lower end of the housing. lt will be understood that these nipples will be connected to the hot and cold water pipes of the Water system. Arranged concentrically within `the housing thus defined is an inner housing, core or sleeve indicated generally at 24, This sleeve has its lower portion of substantially the same external diameter as the internal diameter of the mixing chamber 16, and is provided adjacent to its lower end with an outwardly extending flange 25 to seat upon a lgasket resting upon the shoulder 17 within the housing 10. The sleeve '24 is also provided with `a second annular flange 26 spaced from the flange 25 and which constitutes a seat for the reception of a gasket 27 to be engaged by the annular packing gland `or nut indicated at 28 having external threads as shown to engage with similar threads upon the interior of the housing 1li at the upper end thereof. The exterior diameter of the core or sleeve 24 is substantially reduced between the flanges 25 and 26 as indicated at 29, whereby to provide an elongated water `jacket 36 between the interior wall `of the housing 10 and the exterior wall 29 of the sleeve 24.

The upper end of the sleeve or core 24 receives one end of the rotatable swing spout 31. This spout is of conventional form and is provided at its inner or attaching end with a circular opening to rotatably enclose the upper end of the sleeve 24, being maintained thereon =between the spaced nuts 32 and 33 and is sealed against leakage by the spaced washers or gaskets indicated at 34. The opening 35 in the swing spout communicates with the interior of the core or sleeve 24 by spaced openings 36 radiating from the sleeve as shown.

Arranged concentrically within the longitudinal passage 37 in the sleeve or core 24 is a shaft 38 of smaller diameter than the internal diameter of the core, the said shaft having an enlarged circular head 39 on its lower end disposed within the mixing chamber 16. This head is of less diameter than the interior diameter of the mixing chamber, and has washers or gaskets 40 and 41 on its upper and lower ends to seat alternately, as the shaft 38 `moves longitudinally, against the lower end of the core or sleeve 24 and the shoulder or valve seat 18 at the base of the mixing chamber 16 respectively. The extreme lower end of the shaft 38 has secured thereto as by the screw 42 the upper end of a bell cylinder 43 having its external surface snuglyY engaging the walls of zgssaosl the-inlet chamber 19. Theopposite sides of this Vcylinder are provided with openings 44to communicate at predetermined times with the ports 21-22 constituting the hot Y and coldV water inlets from the system, in a mannerY to be more fully describedhereinafter. The upper or closed. end of the bell cylinder 43 is provided with ports.45'

which establish communication between the interior, of thetbell cylinder'and the mixing chamber 16.

inwardly of its ends the shaft 38 is provided with al screw thread 46 to engage complementary threadsupon the interior of the core or sleeve 24,V the pitch of these threads being suchthat limited rotary movement of the shaft will cause the latterto move the valve head'v 39.10 either closed upper or lower positions or'to intermediate open position within theY mixing Vchamber' 16.. This thread Vinner walls of the core or sleeve 24 immediately below the laterally disposed ports 36 in the said sleeve or core. This valve member 48has anexternal thread S2 which engages complementary threads in the gland member 33, and the crown handle 53 encircling the shaft 38 is secured by threads, as shown, to the said valve member 48. It is obvious from this construction that the valve memberl 48 is movable longitudinally upon the shaft 38 and independently oftheY saidshaft so as to move the gasket 50 `either downwardly in tight engagement with Vthe seat 51 or reversely in anA upward direction to disengage the seat and to establish communication between the internal opening 37'of the core 24 through the ports 36 withthe.y

opening 35in the swing` spout.k Theoperations of the crown handle andthe parts associated therewith are" independent of any movement of the shaft 38.y In other Words, theY valve member 48 may be moved'either to closed or-open positions without disturbingthe shaft 38 and, conversely, the shaft 38 may be rotated. without in any way aiiecting the valve 48.

Arranged within theside wall of the housing vis,an

outwardly extending nipple 54 shown in the present instance as closed by a plug 55. This nipple `communicates as by the opening 56 with the water jacket 30 within the housing 10. This nipple is provided for the attachment of a spray connection if such is desired.

With reference now particularly to Fig. 2 of the drawing, it will be observed that with the handle 47.swungl to the extreme left, the shaft 38 has been rotated to such Cit degree that the openings 44 in the bell cylinder 43- are out of communication with both ports 21 and 22, whereupon no liquid may enter the inlet chamber and the valve is closed. The next position shows the shaft 38 rotated to such extent that one of the ports or openings 44 is in communication with the inlet port 21 to permitV full flow from that port while the opposite port 22 is closed.

. The next or intermediate position of lthe handle 47 shows the bell cylinder 43 moved to Vsuch position that the lateral openingsl 44 therein'are in registry with both ports 21`and 22 where an equal quantity of liquid ofboth temperatures is being fully admitted. The next position shows the bell cylinder moved `to close port 21 and to open port 22while the nal position atthe right showsY the bell cylinderin such position that both of the inlet.`

ports 21-22 are closed. It will beunderstood'by manipula tiugjthe-handle47 the shaft 38-may, be rotated-tof positions intermediatethose shown in FigaZ in ordergto accurately determine :thev temperature -inthe jwater to' ybeA admitted to the inlet chamber as well as to govern the rate of'flow.

It will be observed that the interior diameter of the sleeve or core 2.4 is greater than the external diameter of the shaft 3S enclosed by this sleeve which provides the channel 37V extending throughout the length of the said sleeve, interrupted only'by the complementary threads upon the shaft and sleeve. Thesaid sleeve near its lower end and Vbelow the threads-isprovided ywith.laterally` disposed ports or openings 57 through which liquid in the mixing chamber 16 passes into. the water jacket 30 when the valve head 39 uncovers theseat` 40, vandadditional upper lateral ports or openings 58" are providedii'n the said core or sleeve 24 abovethe complementary threads to enable the liquid to pass from the water jacket 30 back into the channel 37.

Assuming the nipples 23 to be connected respectively with hot and cold water lines,` rotation off theshaftr-SS by manipulation of the handlel 47 will movethep'orts or, openings 44 in the bell cylinder. 431into registryv with; either Vor bothof the hot andy cold water,ports21-22. depending upon the rotative movement of thershatft.` the shaft rotates to open or flow position, the-upper.. end of the valve head 39`wll be moved from the-seat 40, permitting the liquid inthe inlet chamber to pass through ports 45 in the top of the/bell cylinder and into the mix,- ing chamber from whence it passes around thegvalve head and into the lower. portion ofthe annularschannel, 37 surrounding the shaft 38, laterally therefrom throughl the lower'ports 57 into the Water jacket 301,. back:i11,to,`

the channel 37 through theupper ports 58; thence through-g the ports 36 and into the spout head. Withthefvalve; head 48 inthe position shown'in Fig. 1,-thefliquid'passing laterally through openings 36 is unrestricted. 'I'.hisf.;
