2 Sheets-Sheet 1 Filed March '7, 1927 Patented June 17, 1930 LEE G. DANIELS, QF ROCKFORD, ILLINOIS WATER sorcrnivnn Application filed March 7,

This invention relates to watersofteners of the base-exchange type and is principally concerned with those designed for domestic use and, still more particularly, the hand operated type. r

The principal object is to provide a softener having a valve mechanism of an extremely simple and practical form arranged for operation in a novel manner to make it easy for the average person to put the softcner through its regenerations.

It is well known that water softeners have heretofore required three or more valves for the control of the flow of water in softening and regeneration which made it a difiicult task for the average mechanically unskilled person to regenerate the softener. Lengthy instructions had to be furnished withceach softener and these had to be kept at hand for reference by the user on each occasion of regeneration in order to avoid confusion and mistakes. The present invention is principally directed toward avoiding this objectionable feature by providing a single control lever shiftable to different positions to operate the valve mechanism according to a predetermined scheme, the different positions of the lever being clearly indicated preferably by numbers so that the operator is insured against the likelihood of doing anything out of turn. The operation is rendered extremely simple when thus reduced to a matter of routine.

Another important object consists in the provision of a valve with the fewest possible number of ports for accomplishing the operations referred to, enabling a much simpler construction and rendering the valve far more serviceable and less apt to leak. In connection with this valve I have also provided for ample lubrication to prevent stick,

ing of the valve, the lubricant being provided in such a way as to serve in the nature of a fluid seal against leakage, and have also provided an auxiliary valve the only function of which is to control communication between the softener and the waste outlet or drain when the softener is supplied with salt for regeneration and when the salt is 1927.

washed through the bed of water material.

Stillanother important object consists in providing means in connection with the valve mechanism whereby the valve opening in softening and regeneration may be varied to secure a predetermined rate of flow of waterregardless of the available Water pressure in the particular locality where the softener is installed. In the present embodiment where the valve mechanism is operated by a hand lever shiftable to different positrons marked on an index plate, the adjustmentof the valve opening is secured by adustably limiting the movement of the lever when the same arrives at the softening and when the same arrives at the softening and regenerating positions to correspondingly limit the entent of the valve opening in each case.

This application is a continuation in part of my application Serial No. 155,385, filed December 17, 1926.

The invention is illustrated in the accompanymg drawings wherein* Figure 1 is a front View of a softener equipped with an improved valve mechanism in accordance with my invention;

Fig. 6 is an enlarged horizontal sectional detail taken on the line 6-6 of Fig. 1; and

Fig. 7 1s an enlarged vertical sectional detail partly in elevation taken on the broken line 7-7 of Fig. 6.

The same reference numerals are applied .to corresponding parts throughout the views.

The softener comprises a tank 10 serving as a container for a bed of zeolite mineral or other water softening material. Hard watcr is supplied to the softener from a suitable source as, for example, the city water mains, through a pipe 11 and softened water is arranged to be discharged to the service softening y The hard water supply pipe 11, however, 7 is arranged to be placed selectively in communication with either end of the tank through the ,valve mechanism, indicated generally by the reference numeral 17, the

valve mechanism being also arranged to shut off either communication, as will hereinafter appear. In the normal softening operation I the hard water supplied through the pipe exchange,

11 flows through communicating ports in the valve mechanism 17 and passes downwardly through the pipe 13, as indicated by the full line arrow, for discharge into the lower end of the tank beneath the bed of water softening material therein. The distributor pipe, previously. referred to, distributes the, water evenly throughout the vcross-sectional area of the bed for uniform contact with the material and the water in passing upwardly through the bed is soft-- ened and supplied to the service system' through the pipe 12. When the softener is to be regenerated salt or brine is arranged to be injected into a head space in the tank above the bed therein through the neck 18.

The latter has a cap 19 suitably clamped in place by the hand screw device 20. During regeneration the hard water supplied through the pipe 11 is conducted through registering ports in the valvemechanisnr 17 upwardly through the pipe 15, as indicated by the dotted arrow, for discharge into the upper end of the tank. This water picks up and dissolves or assimilates the salt or brine for passage downwardly through the mineral for the purpose of permitting a chemical commonly termed base-exchange, to occur between the brine and the mineral to revive or regenerate the exhausted mineral. The waste water, leaving the lower end of the tank asses upwardly through the pipe 13, as indicated by the dotted arrow, and is conducted to the sewer through a waste pipe 21. Broadly speaking, no invention is claimed in the mere provision of means for introducing hard water at one. end of the tank and discharging soft water at the other end, or in means for controlling the direction of water flow so as to carry brine orjdissolved salt through the mineral in the reverse direction. from the softening flow and discharging the waste water to the sewer. Such means, generally speaking, are well known in this art. However, as will hereifia fter appear, I have proanotheracross an index plate 24. The plate has reference marks, indicated at '25, with suitable legends in connection therewith to aid the operator in shifting the lever in the controlling of the operation of the softener. Thus, the position marked 1Salt indicates the place to which the pointer must be moved by the lever when the softener is to be charged with salt or brine for the regenerating operation. At this point the operator removes the cap 19 and pours in the proper amount of salt or brine and then replaces the cap. The position marked 2--Oif indicates the place to which the pointer must be moved in order to completely shut off the softener to allow the mineral to stand for a time to soak in order that the mineral willhave an opportunity more thoroughly to make a chemical exchange with the brine. The shifting of the'lever to this position is not always necessary if the softener has not been run beyond its prescribed capacity, but every now and then it is found desirable to allow the brine and mineral to soak over night to relieve a more than ordinary exhausted condition of the mineral. Tl1lS method of regenerating the softener has the advantage of economy in the amount of salt or brine required. The

shifts just described. In this position the softener is in its normal softening operation. Just after regeneration it is usually a good practice to open a bib near the softener as, for example, in a laundry tub, long enough to allow all of the hard water in the head space in the tank to be flushed Upon the sure.

can be confined to a predetermined desired rate irrespective of the available water pres- The water will not, therefore, pass through the mineral bed at a rate beyond that at which it can be properly softened.

A lock nut 29 serves to hold the set screw 26 in its adjusted position. In a like manner the screw 27 limits the movement'ofthe lever 22 when it is moved to the position marked 3Wash and. the adjustment of this screw serves to vary the amount of valve opening for the regeneration flow. Accordingly the brine will not be washed through the mineral beyond a rate at which a complete chemical exchange can properly occur between the brine and the mineral regardless of the available water pressure. The lock nut 30 serves to hold the set screw 27 in its adjusted position. The plate 24 may obviously be supported in any suitable manner but for convenience I have provided the same with a flange 31 to receive screws 32 for fastening the plate to the body 33 of the main valve.

Referring now, more particularly, to Figs. 6 and 7 in which the valve mechanism 17 is illustrated in detail, it will be observed that the body 33 of the main valve has the hard water supply pipe 11 threading in a boss 34 at the rear thereof, A' hollow valve plug 35 of tapered form is received in a bore 36 of complementary form provided in the body 33. Two ports 37 and 38 of elongated form are provided in the body 33 opening into the bore 36 at the lower and upper sides thereof, as indicated in Fig. 7. The port 37 opens into a boss 39 into which the pipe 13 leading to the lower end of the tank 10 is threaded while the port 38 opens into a boss 40 wherein the pipe 15 is threaded. The valve plug 35 has a single port 41 of elongated form arranged to register with eitherone of the ports 37 and 38. When the port 41 is in registry with the port 37'the lever 22 is in the softenin position indicated by the marking 4-Soi t on the plate 24, and when the port .41 is in register with the port 38 the lever 22 is in the regenerating position market 3-Wash.' The way in which the valveopenings for these two positions are adjusted by adjustment of the set screws 26 and 27 it is believed will now be apparent.

In Fig. 7 the port 41 is in full registry with theport 37 but an adjustment .of the set screw 26 will serve to restrict the ports to less. than full registration. The valve plug 35 is open at the rear, .as shown at 42, so

that the interior thereof is always in communication with the hard water supply pipe 11. The front end of the valve plug is closed and has a steam 43 extending outwardly through a hollow boss 44 to receive the hand lever 22 at its outer end. A coiled compression s ring 45 received in the boss. 44 andacting etween the valve body 33 and a washer 46 on the stem 43 serves to hold the valve a snug fluid-tight fit. The plug 47 threading into an opening 48 at the rear of the valve body 33 affords access to the valve plug and, of course, permits the removal and replacement thereof. Two annular grooves 49 and 50 are provided in the valve body 33 near the opposite ends of the bore 36 and having a communicating groove 51 extending longitudinally relative to the bore. These grooves are supplied with lubricant plug 35 seated in the bore 36 with under pressure by the grease cup 52. The

circumferential lubrication at the opposite ends of the bore insures easy turning of the valve plug and also provides a fluid seal cant along practically the entire length of the plug. In addition to the fact that a fluid seal against leakage is provided by this manner of lubrication it should be observed that the ample displacement of the ports 37 and 38 in the valve body is in a large measure a protection against leakage and insures long satisfactory service. It is only by reason of the fact that I have reduced the number of ports positively to a minimum that such protection against leakage is afforded, as it will be obvious that a valve designed with numerous ports would prove unsatisfactory on account of leakage unless the valve were built of sufliciently large proportions so as to displace the ports to the proper distances and, of course, a valve designed along such lines would be expensive and imractical for the present purposes besides Eeing'hard to operate.

In connection with the main valve I have provided an auxiliar valve 53 of the quickopening and self-c osing type commonly known as a whistle valve. This valve provides a seat 54 between the .inlet and outlet nated b the reference numeral 59, is thus held to its seatpartially under the pressure of the water in the pipe 60 communicating with the inlet end, the pipe 60 being connected,.as at 61, with the pipe 13. The outlet end 56 is connected with the waste pipe 21, previously referred to, which. communicates with the sewer. The disk 59 is also normal- 1y held seated under the action'of a compression spring 62 acting between the disk 59 and a hollow plug 63 threading into the valve body. The disk 59 has a stem or spindle 64 extending therefrom through a packland nut 65 to project from the valve In D bofiy for operation by a cam lever 66. The

latter is pivoted at 67 on a bracket 68 mount ed on the valve body and in its inoperative position has a stop portion 69 thereof engaging the bracket 68 to hold the'free end of the lever 66 in a predetermined relation to the lever 22, as indicated in full lines in Fig. 6. The valve disk 59 is, as stated be- I inclusive.

fore, normally held closed but when the lever 22 is moved from the softening position in which it is shown in Fig. 1, the lever 22 comes into engagement with the lever 66 and moves it to the dotted line position shown in Fig. 6, to open the valve '53. When the lever 22 is in the position marked 1'Salt, the valve 53 is opened slightly, as represented in Fig. 3, but whenthe lever is moved still farther to the position marked 3-'-VVash the valve 53 is fully opened, as represented in Fig.5. In positions intermediate the l-- Soft position and the 2-Oif position of the hand lever 22 and, of course, in the marked 4Soft thereof, the valve 53 remains closed because the lever 22 is not in engage-.

ment with the lever 66 in these positions. For convenience in the mounting of the auxiliary valve 53 alongside the main valve a bracket 70 may be provided arranged to be fastened, as by means of screws 71, to a lug 7 2 provided on the valve body 33, the bracket 7 0 having an opening 73 for the reception of thepi e 21 and being equipped with a set screw 4 for fastening the pipe 21 in position with the auxiliary valve in a proper definite relation to the main valve-where the cam lever 66- is properly disposed with respect to the hand lever 22. I

In operation, the valve mechanism is arranged to be set in four different positionsas diagrammatically illustrated in Figs. 25

In the normal softening operation, as illustrated in Fig. 2, the plug of the main valve has its port 41 in register with the port 37 to conduct the hard water supplied through the ipe'll down through the pipe 13." The auxi iary valve 53 is closed and the disk 59 thereof, in additionto being held seatedby the spring. 62, is urged toward its seat under the pressure of the water in the pipe 13. through the communication established by the pipe connections nism is shown shifted to the salt filling posi-' tion herein called the 1Sa1t position. It will be observed that the valve plug 35 has its port 41 intermediate the ports 37 and 38 so that there is no communication between .the hard water supply pipe 11 and either of the pipes 13 and 15. The auxiliary valve, however, is partially opened and establishes communication between the pipe 13 and the waste pipe21. This permits the tank to drain a certain amount when the cap 19 is removed for the pouring of salt into the tank. The lowering in level of the water in the tank avoids overflowing when the salt is poured in. After the salt has been poured in and the cap 19 is replaced the valve mechanism may be shifted to the position 2- Off for the soaking operation. This position is illustrated in Fig. 4. It will be observed that both of the valves are closed so that the softener is completely shut off. After the soaking operation the valve mechanism is shifted to the position 3-Wash illustrated in Fig. 5. Here it will be observed that the hard water supply pipe is placed in communication with the pipe 15 by reason of the registry of the ports 41 and 38. The water entering the top of the tank washes the salt down through the bed of water softening material and the waste water issuin from the bottom of the tank is conducte upwardly through the pipe 13 and out through the pipe connections 61 and through the valve 53 and waste pipe 21 to the sewer. The valve 53, it will be seen, is fully opened. After the regeneration is completed the valve mechanism is shifted back to the 4-Soft position for normal softening operation.

It is believedv the fore oing description conveys a clear understanding of my invention and all of its objects and advantages. It should be apparent that the invention is not to be limited in itsapplication to the particular embodiment shown as the same with a softener tank containing softening 1 material, means for establishing communication between sa1d tank and a source of hard water supply, and means for establishing communication between said tank and a service system, of a valve for controlling communication between the first means and said tank whereb to introduce hard water into either end 0 said tank, a waste outlet, another valve for controlling communication between said tank and said waste outlet, and a hand lever for operating one of said valves in the swinging movement thereof, said lever being arranged in a certain position to also operate the other valve.
