JACOB T. JOHNSON, OF ATLANTA, GEORGIA.

COMBINATION FAUCET.

Application filed. June 15, 1922. Serial No. 568,612.

To all LU/10771217717261, concern Be it known that 1, Jason T. JOHNSON, a citizen of United States, residing at Atlanta, in the county 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 the accompanying drawing.

The present invention relates generally to combination faucets for controlling the flow of a plurality of streams, such as hot and cold water, and aims to provide a novel and improved valve structure of that kind.

Another object is the provision of such a combination faucet or valve including novel means for controlling the flow of hot and cold water or other liquids, and also com-- prising a novel construction and assemblage of the component elements, to provide an efficient, convenient and practical faucet or valve which is also simple in construction and economical to manufacture, install and maintain.

A further object is the provision of such a faucet or valve including a slidable valve member instead of rotary valve members as disclosed in my Patent No. 1,336,286, granted April 6, 1920, and application Serial No. 526,942, filed January 4, 1922.

With the foregoing and other objects in view, which will be apparent as the description proceeds, the-invention resides in the construction and arrangement of parts, as hereinafter described and claimed, it being understood that changes can be made within the scope of what is claimed, without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawings, wherein Figure 1 is a median vertical reaction of the faucet. portions being shown in elevation.

' Fig. 2 is a section on the line 22 of Fig. 1.

Fig. 3 is an elevation of a modified construction, the discharge portion of the casing being shown in section.

Fig. 4 is a view similar to Fig. 1 showing another variation.

Fig. 5 is a cross section on the line 5-5 of Fig. 4.

The body or casing 10 is of suitable metal and has a vertical or longitudinal chamber 11 preferably of rectangular or non-circular the cold and

hot water inlets

12 and 13, re-

spectively, leading to the opposite sides of the smooth wall of said chamber, between the ends thereof. The casing has bosses or connections 14 for the hot and cold water supply pipes from which the inlets extend to the chamber, and said inlets are preferably wide transversely of the chamber and of minimum width longitudinally of the chamber, so as not to require excessive longitudinal movement of the valve member. The lower end of the casing terminates in a discharge nippel or nozzle 15, said end of the casing having an outlet extending through said nozzle or outlet portion, and the lower end portion of the chamber 11 is gradually reduced in diameter or tapered, as at 16, so that the wall of the chamber converges and merges into the nozzle or outlet portion to provide a valve seat at the upper end of said nozzle.

The valve member 17 is of a shape to fit snugly in the chamber 11 for longitudinal sliding movement, but is constrained so as not to rotate. The stem or rod 18 for operating the valve member is swivelled through. said valve member, centrally within the chamber 11 and valve member, said stem extending loosely through a central opening in the valve member, and having a flange or head 19 abutting the lower end of the valve member. A valve tip or head 20 is secured to the flange 19 at the. lower end of the stem, and is of rubber, fibre or similar material, to seat snugly on the lower portion or seat of the casing over the discharge outlet with a compression fit. This valve tip 20 closes the discharge port of the valve when the valve member is forced down tight, thereby shutting off the flow from the casing. The stem 18 has screw-threads 21 above the valve member, and a nut 22 is threaded on the stem to bear against the upper end of the valve member 17, for compelling the valve member to move with said stem, and to provide the swivel connection to permit the stem or rod to turn in the valve member with the valve member movable longitudinally with said stem. The valve member has a recess or cavity 23 in the upper end thereof in which the nut 22 is disposed so that the nut and valve member can be nested together when the valve member is raised, to provide a compact arrangement.

channels are adapted to register with the respective inletsorports -.l2 and 13 in suecession, saidupperends of the passages be- ..inglocated at spaced :points longitudinally of the valve member, whereby the passage registers with the inlet 12 beforethe pasfsage'25 registers with the inlet 13 when the valve member is slid upwardly. The lower .end ofthe valvemember l7 isot tapered or conical :form, with the valve tip 20 at-the apex thereof, and the

passages

24 and 25 openattheir lower ends at said conical end of the valve member atopposite sides of the valve tip20. I

In order toslide .the valve member when the stem '18 isrotated, a member 26 is threaded into the-upper end of the casing and seats on a shoulder 27 at .the upper end of the chamber 11, and said member 26 has a central dropped nut portion 28 through which the threaded portion of the stem is screwed, thereby compelling the stem to travel longitudinally when it is rotated for sliding the .valve member. The recess or cavity 23 will accommodate the nut portion 28 when the valve member is moved to'its uppermost position. v

The stem 18' has a portion 25) of reduced diameter projecting .out of the casing and havinga suitable handle 30, and a packing cap 31 is threaded on the upper end portion of the casing. A disk 32 bears on the upper end of the casing and member 26 and ,packing 33 is confined between said disk 32 and cap 31 for preventing leakage, the portion 29 of the stem projectingthrough said disk, packing and cap. The dropped portion 28 is sufliciently spaced from the disk 32 to en able the threaded portion 21 of the stem to travel upwardly the required amount to completely raise the valve member, without the threads entering the packing. The memvher 26 is formed for .the engagement of a wrench therein to apply and remove said anember when the cap 31 and packing have been removed from the casing.

When the valve stem 18 is screwed down tight, the valve member 17 is slid down so that it closes the

inlets

12 and 13 and presses the tip 20 over the outlet 15. Thus, both inlets and also the .outlet are closed, to pre vent the discharge of either hot or cold .water, or to prevent the backing up of either hot or cold water into the opposite supply pipe, inasmuch as eommnnieation between the inlets is shut ofi. This will effectively prevent leakage when the valve is closed. By screwing the 'stemupwardly, the

ly further, the passage 24 starts to move out of registration with the port 12, and the passage 25 starts to move into registration with the .hot water inlet 13, whereby hot and cold water are discharged -.through the valve member to mix within the lower portion 'of the chamber 11 around the valve tip 20 and discharge through the outlet. 15. The temperature of the discharged water can be regulated by adjusting the valve member upwardly and downwardly whereby the passagesQd and 25 register more or less with'the

corresponding inlets

12 and 13. It i will also be observed that the streams ot' hot and cold water flowing through in the passages or channels 25and 24,-respeetively, are

directed downwardly towardthe outlet, before the streams meetone another, and the tapered portion 16 ofthe casing will direct the streams together through the outlet. This will prevent the head-on collision of the streams as well as reducing the-objectionable noise or vibration of the fixture and plumbing. The streams are brought together gently but will, nevertheless, mix thoroughly in passing to and through the out let. The mixing of the hot and cold water is thus delayed until the streams are 'di-' rected toward the outlet, which will minimize the disturbance within the casing resulting from the discharging streams ofi water under pressure and the commingling thereof. This will also reduce the agitation or spraying of the water when discharged from the outlet. By raising the valve member further, to bring the upper end o'f the passage 24L completely above the inlet .12, with the passage .25 in registration with the inlet 13, the fiow of cold water is shut ofl, and hot water alone is delivered, the flow of hot water being controlled or reduced by raising the valve member to gradually reduce the flow of hot Water by the partial movement of the passage 25 out of registration with the hot water inlet 13.

then the flow of cold water being stopped,

just reverse to the manner, as above descrlbed, 1n ralsing the valve member.

The pitch of the screw-threads can be suchas to require several turns of the stem tg-Slldfi the valve member to extreme post tions, or so as only to require a part of a complete turn of the stem by making the screw-thread quicker.

Fig. 3 shows a similar faucet or valve, wherein the discharge portion is extended to one side to provide a horizontal nipple 15" for the connection of a hose, pipe, or the like, which is especially desirable for a shower device or appliance, shampoo device, or the like.

In the modified construct-ion shown in Figs. 4. and 5, the several parts are the same as described hereinbefore, excepting as hereinafter noted. The lower terminal of the valve stem 18 does not extend through the valve member 17 but simple enters the upper end portion thereof, and is provided with an annular groove 19 receiving a screw 19 or other element en aged in the valve member for swivelling the stem to the valve member, instead of having the stem pass through the valve member and provided with a flange 19 below the valve member, as seen in Fig. 1. In this case the tip 20 is se cured direct to the lower end of the valve member, and does not rotate with the valve stem as with the first form, the tip 20 having a short shank 20 entering a recess in the lower end of the valve member, and the tip being secured to the valve member by means of a screw 20* or the like. With the arrangement shown in Fig. 4:, the valve tip 20 is carried by the lower end of the valve member and does not turn, whereas, as seen in Fig. 1, the tip 20 is carried by the lower end of the valve stem to rotate. A further variation consists in the fact that the

channels

24 and 25 are open throughout their lengths at the sides of the valve member. Otherwise, the construction as shown in Figs. 4 and 5 is the same as shown in Figs. 1 and 2, and the operation is substantially the same.

Having thus described the invention, what is claimed as new is 1. A valve comprising a casing having inlets and an outlet, a valve member slidable in the casing and having a conical end with a valve tip at the apex of said end to seat across said outlet, said valve member having separate channels extending to said conical end and adapted to communicate in succession with said inlets, and a stem connected to said valve member for sliding it in the casing.

2. A valve comprising a casing having side inlets and an outlet at one end, a valve member slidable in said casing and having a conical end with a valve tip at the apex of said end to seat across said outlet, and a stem connected to said valve member for sliding it in the casing, said valve member having separate channels at opposite sides of said stem and valve tip extending to said conical end of the valve member, and adapted to communicate in succession with said signature.
