COMBINATION FAUCET.

Application tiled December 20, 1922. Serial No. 608,044.

To all whom it may conce/rn.'

Be it known that JACOB T. JOHNSON, a citizen of United States, residing at Atlanta, in the Icounty of Fulton and State of Georgia, have invented certain new and useful Improvements in Combination Faucets, of which the following is a specification, reference being had therein to thel accompanying drawings.

The present invention relates generally to valves and faucets, more particularly combination hot and cold water faucets, such as are used for discharging hot or cold water or a mixture thereof for bath tubs, kitchen sinks, wash stands, barber shops, wall showers, and the like, and the invention forming the subject matter of the present application is an improvement in or another species in addition to the combination faucets disclosed in my Patent No. 1,336,236 granted April 6, 1920, and in my copending applications Serial Nos. 504,584 and 526,942 led Oct. 1,1921, and January 4, 1922, respectively.

In addition to the general object in providing a practical and eflicient valve or faucet of that kind requiring the operation of only a single operating handle or member, as in the patent and applications supra, it is the object of the invention to provide a novel and improved valve member for controlling the flow of hot and cold water and the discharge thereof, and for the further purpose of directin the hot and cold water to a mixing cham r in such a way that there is no liability for either stream of water being backed up, such as when one stream is delivered at a higher pressure to the faucet or valve than the other stream.

Another object is the provision of such a valve or faucet in which the two liquids do not comingle until they move in the same direction toward the discharge outlet, to avoid back pressure on either stream of liquid, the two streams being prevented from having a headpn collision in the faucet, to avoid jars and vibrations, as well as eliminating back pressure on either stream.

A further object is the provision in such a faucet or valve of novel means for breaking up or dividing the streams of liquid, so as to avoid the whirling or agitated disin open position, portions being shown in' elevation.

Fig. 2 is a vertical section of the valve member taken on the line 2-2 -of Fi 1, at right angles tothe line of view in rig. 1, the stem being shown in elevation.

Figs. 3 and 4 are horizontal sections on the respective lines 3 3 and 4 4 of F 1.

Fig. 5 is a view somewhat similar toli 1, showing a modified construction, wit the valve member partly in elevation and partly in sectim.

Figs. 6, 7 and 8 are elevations of valve members having 'different forms of ports therein.

Fig. 9 is a cross-'section on the line -9-9 of Fig. 8.

Fig. 10 is a crosssection of another modied form of valve member having the channels open at the peripheryU er opposite sides of the valve member.

Fig. 11 is a cross section of another valve member showing a further modification.

Referring to Figs. 1, 2, 3 and 4, the body or casing 14 is of suitable metal and has a vertical chamber 15 and hot and cold water inlet passages 1 6 and 17, respectively, leading to the opposite sides of a smooth cylindrical wall of the chamber 15, said Casin having suitable means for the connection o hot and cold water supply pipes. The lower end of the casing terminates in a discharge nipple or nozzle 18, and the lower end of the chamber 15 is gradually reduced in diameter or tapered, as at 19, so that the wall of the chamber converges and merges into the nozzle or outlet portion 18 to provide a valve seat at the upper end of said nozzle. The chamber 15 is internally screw-thread ed, as at Q0, at a point above the

passages

16 and 17, and the upper end of the chamber 15 is closed by a cap 21 threaded onto the upper end of the casing.

The valve member 2.2 is externally screwthreade-d as at 23;. near its upper end to engage the screwthreads 20. for the longitudinal or axial movement of the valve member within the chamber 15 when the valve member is rotated, it being noted that the screwthreads between the valve member and casing are located at that side of the

passages

16 and 17 opposite to the outlet ol' the casing. The valve member has a smooth c vlindrical surface fitting the smooth qvlindrieal vvall of the chamber 15 below the screw threads. v

The valve stem or rod 24 extends longitudinally through the valve member at the axis thereof, for turning the valve member, and the upper terminal of said. stem projects through the cap 21 and has a suitable handle 25 for conveniently turning the valve member. A rubber or other suitable gasket or packing Q6 is disposed around the stem 2l to bear and tit against the cap 21 on the interior thereof` so as to prevent leakage of the water past the cap. Said gasket or packingl is retained in place by a metal disk or washer 27 seated on the upper end of the easing. although any necessary or suitable packing can be used.

In order to control the flow of hot and cold water, the valve member 22 is provided at, opposite sides of its axis with the-longitudinal channels or passages 2S and 39 extending to the lower end ot the valve niember, and the upper ends of said channels or passages open at the opposite sides o1' the valve member between the ends o l` the smooth cylindrical surface of said member. to provide the respective hot and

cold water ports

30 and 31 to register with the hot and cold Water passages 1G and 17. The ports ll and 31 are so arranged that either ot them may fully register with the corresponding inlet passage, or the two ports may partially register with both inlet passages when a mixA ture of hot and cold water is wante'l. The contol of hot and cold water is obtained bv turning the valve member.

The discharge of water from the valve is prevented when the valve member is screwed down, and,for this purpose` the lower end of the valve member has a depending linger or reduced portion 3Q. through which the valve stem or rod Qt extends. The linger or stud 32 is arranged rentrall)v of the valve member and easing. and the stem 2l has a collar or enlargement Bil seating against or abutting the end of the linger 32. and said stem also has a collar illV bearing against the upper end of the valve member7 to secure the stem to said member, although other means of attachment may be used, A Valve tip or washer 35 is secured to the collar or terminal portion 33 of the stem 24, to be moved with the valve member, and may be of rubber` fibre or other material to have a compression lit on the valve seat surrounding the outlet` so that when the valve member is screwed downwardly, the valve tip 35 will seat over the discharge port or outlet with a compression lit to tightly close said outlet, thereby providing a compression valve structure." rl`he discharge of any water from the easing is therefore shut olf when the valve member is screwed down, and, furthermore, when the valve member is in this position, the ports il() and 31 are out of registration with the

passages

16 and 17, so that the valve member extends across and closes the passages 1G and 17. while the Wall of the easing extends across and closes` the

ports

30 and 31. The inlet passages and outlet of the easing and passages of the valve member are therefore all closed when the valve member is in closed position. to prevent leakage and to also relieve the packing of pressure.

lVhen the valve member is screwed upwardly, the discharge port or outlet is opened, and the ports 3() and 31 of the valve member can then be brought into and out ot registration with the inlet passages for the discharge of hot or cold water, or a desired mixture thereof when water of an intermediate temperature is wanted. The pas sages or channels 2R and-Q9 of the valve member will direct the hot and cold Water from the inlet passages longitudinall)Y in the valve member to discharge at opposite .sides of the finger 3Q into the mixing cham her between the discharge end of the casing and lower end of the valve member. The, hot and cold water are therefore directed toward the outlet before comingling, and this eliminates the possibilit)1 of either stream being barked up or subject to back inessure. such as when one stream is delivered to the valve at greater pressure than the other stream. The valve member also prevents the streams from mixing in the valve member until they are discharged :from the valve member. The inflowing streams cannot. therefore, have a head-on collision in the valve.. such as would produce a jarring or vibration of the plumbing, or'

the bark pressure on either stream.

Means is provided for reducing or eliminating the splashing or spraying of the water in discharging' from the valve. Thus. the lower end of the valve member is formed with an annular recess 2G surround ing the finger or stud 3Q. and forming an annular shirt 37 at the end of the valve member titting the wall of the casing and .spaced from the finger 32. with the passages or channels Q8 opening into thc recess 36 between said skirt and finger. A fiat ring 38 is fitted between the edge portion ot' the skirt 37 and the finger 32, said ringv tit ting around the linger within the recessed end of the valve member, and said ring,r has the annular series of apertures 89. so that the ring provides a strainer for the discharge end of the valve member. Thus. the water flowing4 from either or both pas-- sages or channels of the valve meinber will pass into the recess 36, and the streams will be broken or divided up by the apertures IW. so that the Water will flow from the \alve member in jets into the mixingt eliamber. This will prevent the sudden rush ot' the water into the mixing chamber. and the whirling motion of the water in said elianr ber or through the outlet. and, as a result. the water has a smooth mixing action. t'oithe smooth discharge of the water from the valve, without si'naving or splashingr objeetionably. As shown. the ring or strainer 38 a piece separate from the valve niember having a friction tit with the sltirt Ib' and ngger in order that said rin;r eau be removed for elearning or replacement.

Fig. 5 illustrates a moditieation. in that the screw threads of the. valve member 2;) are formed on a sleeve or collar 223 ieniov ablv fitted on the up )er end portion ot the valve member. and t'Ihat the serew threads of the easing are formed in a bushingT "tl removablv fitted in the upper end portion of the casinaT 14., whereb)Y said threaded portions of the valve member and easing can be replaced when worn out or damaged. ln this construction. the valve stem "il" is also shown as beiner integral with the upper enfl of the valve member.

Figs. G, 7 and 8 show the ports ti. Iii and 31C of the respeetive valve member,`1 ot different shapes, each port havingl a large end for full registration with the worrespondiner inlet passage and a tail otl narrower width for restrictingr the tlow as the larger or wider end is moved awav from thtx inlet passage.

Fig. 9 shows the valve member 2;) with the opposite ports C and fill' otl the .shape shown in Fig, and the passages or ehair nels QS" and 29 of the valve member are also of greater width than shown iu lfitr. il. said passages being: of widths equal to the lengths oithe ports. whereby to prov ide t'ftr :i greater turniinr movement ot tite valvtl member in eontrollineY the tlow ot hot and wld water. which mav be espeeialljy lesii able for showers.
