vide a new and improved multiple control valve designed for hand operation which is relatively simple in construction and easy to service.

Another object of my invention is to -provide a new and improved multiple control valve which is so constructed that the number of working lparts is held to a relative minimum so that the ydevice is inexpensive both from the point of View rof construction and operation. n

Another object of my invention is to provide a new and improved multiple control valve incorporating a relatively large number of valve chambers and valves which are all housed within a single valve casing. Still another object is to provide a multiple control valve which houseswithin a single casing two separate sets of valve chambers separated respectively by a set of valves and a set of auxiliary 'chambers adapted to contain means for operating the valve wherein only one element thereof need extend through the outside casing wall in such a manner as to require a packing.

A further obiect of my invention is to provide 'a relatively simple multiple control valve in which the valve casing can be separated into two sections and the parts readily removed and then reassembled with such new parts added as may be necessary. i A still further object is to provide a unitary multiple control valve with chambers having such sizes with relation to the pipes connected thereto that there will be no restriction in the flow of water through the valve.

With these and other objects in View, my invention consists in the construction, arrangement and combination of the various parts of my device whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out invmy claims and illustrated in the accompanying drawings, in which: Y

Figurel is a perspective view of my valve device showing a longitudinalsection of the mid portion or the valve with the valves having the position normally occupied when the device is set up for delivery of softened water.

Figure 2 isa side elevational view of my device similar to the View in Figure 1 showing the relative positionof we valves tor a brilins Operation.

Figure 3 is a longitudinal sectional view similar to Figure 2 showing the valves in the position occupied when the mineral tank is being regenerated.

Figure 4 is a longitudinal elevation View showing the relative positions of the valves when the mineral bed is being backwashed.

Figure 5 is a perspective view of a softening apparatus showing a mineral tank, a brine tank and a control valve of my design attached adjacent the mineral tank.

It has been common practice in the past to supply a water softening apparatus which utilizes mineral softening materials of the nature of Zeolite. vWhen this sort of material is used its water softening potentiality becomes spent as the ap paratus continues in operation. After the material is no longer capable of softening water it is washed with brine to renew its softening effect, then washed and subsequently backwashed before the device is again ready for further use. Because of the fact that all of these operations involve the passage of water or liquids in one direction or another it becomes necessary to control their iiow by means of valves so that the flow will be directed to the proper places and in proper sequence.

While it has been possible to control the operation of water-softening apparatus with different sets of individual valves coupled with a cam or other operation mechanism it has become desirable for efficient operation to produce a compact, eicient valve wherein all of the parts are in a single casing and adapted to control at one point ail of the various operations required of the separate valves.

This invention is devoted to the preparation and building of a compact valve to which all liquid lines are led so that a unitary control may be produced which will operate properly at all times. t is desirable also in a valve of this kind to direct the flow of fresh hard water under pressure through all of the several chambers without there being likelihood of a leak between valve chambers filled with water and other valve chambers which are not being utilized at some particular phase of operation.

In water softening devices of this general description which have been in use in the past it has been the custom to employ separate valves individually operated. ln a few rare instances where all of the valves have been grouped together their separate identity has been maintained so that each and every. valve member acts separately without advantage being taken of the fact that part of one valve may at the same time serve equally well as part of another valve. AsY a result valves which have heretofore been employed for the control of water softening devices have been cumbersome, complicated and ineiicient and as a result of these characteristics have been quite generally expensive.

In the embodiment chosen to illustrate the principles of my invention there is shown a multiple control valve designed for manual operation comprising a body l@ having a cover plate ll connected by means o a system of pipes to, a mineral wate softening tank l2 and a brine tank I4. The tanks normally rast' upon a base i6 and are customarily encased within a cover, suggested by the dotted lines I8.

In the perspective view of the casing shown in Figure l the multiple valve device has been sectioned through the mid portion longitudinally so as to reveal all or the internal working parts. Mechanical details illustrating attachment of the cover plate have been omitted for the sake of simplicity.

Within the valve casing there is provided a set of primary valve chambers comprising a. triple chamber 2d andl

individual chambers

2l, 22 and 23. A fresh hard Water supply pipe 24 connected to a source of supply communicates with the chamber 2. A soft water discharge pipe 25 communicates with the chamber 2| and is designed to conduct water softened by the device tO a place where it will be utilized.

Within the casing there is likewise provided a set of secondary valve chambers comprising a pair of

single chambers

26 and 21 both located immcdiately adjacent the triple chamber Z. A double chamber 28 lies adjacent one end of the chamber 2o and the chamber 2| and is connected to the chamber 22 by a short aperture 29. secondV double chamber 3Q completes the set oi secondary valve chambers and lies immediately adjacent both

primary chambers

22 and 23.

For connecting the primary chambers with the secondary chambers there is provided a set of passages comprising a plurality of apertures 3|, 32, 33, 3d, 35' and 36 each provided with a sleeve 31 threadedly engaging the aperture and forming a valve scat in the primary chamber in each case.

A set of valve members is provided which are uniform in size and construction. Each member includes a valve element d8 formed in the shape of an inverted cup within which is positioned a relatively soft seat di. rI'he cup-shaped member together with the seat is attached in each case to a valve stem i2 by means of a screw 231 in order that the valves may be normally held in closed position there is provided a spring keeper fill attached to the valve stem upon which is positioned a coiled spring d which is compressed between the spring keeper and the top of the respective secondary chamber in which it is located.

A pipe et leads from a fitting 5i at the top of the mineral tank to a ntting 52 at the rear of the multiple contral valve from which one branch line 53 is in constant open communication with the secondary valve chamb;r 25. Another branch line 5d from the T tting is in oonstant valve chamber 23.

A pipe line 5 of relatively smaller size leads from the secondary chamber 21 downwardly to an. L fitting' 51 from which it is directed into the bottom of the brine tank. Still another pipe 58 open communication with the primary communicates between the bottom of the mineral tank and the secondary chamber 28. A drain pipe 59 is in constant open communication with the secondary valve chamber 30 and leads downwardly to a convenient point.

The top of the brine tank is connected by a, means of a short pipe 6D to the top of the mineral tank, there being provided a hand operated shutofi valve @I in the short pipe line to shut o the line when desired.

Beneath the set of secondary valve chambers, as viewed especially in Figure l, there is provided a set of cam chambers comprising respectively the chambers 65, 66 and 61. These cam chambers are closed pockets when the valve casing is closed by the plate Il and have no means of communica-tion between each other or with any of the other chambers within the valve casing.

For positioning the valves for different phases of operation there is provided a cam shaft 58 which has' a hand wheel 69 attached on one end tok provide for manual rotation. The shaft extends through an aperture 64 located partially within a threaded boss 10 at one end of the valve casing. A packing nut 1I serves to conne a mass or packing 12 around the cam shaft thereby providing the only packed aperture in the valve casing.

rlhe cam shaft extends from the boss laterally through all of the cam chambers passing through apertures '.f and 18 in the walls 13 and 14 which separate the cam chambers. At the opposite end 11 the cam shaft is rotatably secured by means of a key 1-3 in an end wall 19 of the valve casing. A snug rotating fit is provided wherever the shaft is supported within the valve casing. Partition walls, 8G, 8| and 82 separate respectively the cam chambers 65, 66 and 61 from the adjacent secondary valve chambers. These partition walls have respectively a series of

apertures

33, 84, 85, 86, 31 and 88 within which the valve stems i4 are snugly but slidably mounted. The valve stems in each case extend clear through the apertures into the cam chambers. So that the valve stems may be suitably sealed against passage oi liquid in the valve chambers, which is seldom under any appreciable pressure, the apertures may be sealed With a heavy grease or by some similar means which will resist the iiow of liquid through them.

For lifting the valve adjacent the secondary chamber 2% th` re is provided a cam 90 having two cam faces thereon angularly spaced one with respect to the other so that when the cam shaft is rotated there will be two points within a 360 rotation at which the cam will bear against the valve stem and press it upwardly in order to open the valve against its spring pressure. A second cam S2 on the cam shaft is also positioned within the cam chamber and has a single cam face thereon designed to lift the valve adjacent the secondary valve chamber 21.

Within the cam chamber 6% are tWo

cams

93 and 94 having a single cam face on each so positioned that they respectively lift and open the valves adjacent the secondary valve chamber 28 at the proper intervals. Within the cam chamber 61 there is provided a cam 95 having two faces here shown spaced at approximately intervals for lifting and opening the valve in primary chamber 22. A single cam 96 in the same cam chamber operates to open the valve in primary chamber 23. It is contemplated that in each of the apertures which extend into the cam chambers wherein a moving part either rotates or res, ciprocates the apertures will be suitably packed or the moving part will be suitably tted so that there will be n-o appreciable :passage of liquid through those apertures.

In operation the multiple control valve is initially set in a soft-operating position. This is the position illustrated in Figure 1. With the valve in this position a fresh hard water supply is drawn from the water main and passed through the valve and thence into the top of the mineral tank wherein it passes through a bed of Water softening mineral to the bottom of the tank from which it is withdrawn, passes again through the valve, and thence is passed outwardly through a pipe to the point of consumption.

Specifically when it is desired to set the control Valve in soft-operating position the hand Wheel B9 is rotated to a point where a designation Operate von the rim of the wheel is located opposite a pointer on the casing. In this position one face of the cam 90 bears against the valve stem in chamber 26 opening the valve so as to permit passage of fresh hard water from the pipe 24 through the primary chamber 20, the secondary chamber 26 and thence outwardlyto the branch line 53, the T 52 and the pipe 50 into the top of the mineral tank. From here the water passes down through the mineral bed, outwardly at the bottom into the pipe 58 from which it is led back to the valve casing where it enters the secondary valve chamber 28. At the same time the cam 94 is positioned as shown in Figure 1 so that the cam face lifts the valve in primary chamber 2| and, since the valve in chamber 22 is closed, water thus softened by passage through the mineral bed passes upwardly from the chamsber 28 into the chamber 2| and thence outwardly from the casing through the discharge pipe 25 to a point where it will be used. It will be noted that all of the remaining valves stand in closed position.

When it becomes necessary to pass brine through the mineral bed the hand wheel is rotated until the appropriate designation on the hand Wheel is opposite the indicator |60. This will place the camson the cam shaft in the positions shown in Figure 2, at which brine induction takes place.

As there illustrated cam 92 is rotated so that the cam face lifts the valve adjacent the second'- ary chamber 2'1 to open position. Meanwhile cam 90 has rotated past its respective valve stem permitting the valve to close. Fresh hard water will then pass from the pipe 24 into the primary chamber and thence through the valve into the secondary chamber 2l from which it passes outwardly through the pipe 56 and L 51 into the bottom of the brine tank. The liquid contents of the brine tank will then be subject to pressure of water in the -hard Water supply line. The pressure of water thus introduced into the bottom of the brine tank causes the brine within the tank to pass outwardly at the top through the connection 60 into the top of the mineral tank, the valve 6| having been opened.

Brine then passes downwardly through the mineral bed and outwardly at the bottom through the pipe 5into the secondary valve chamber 28. In the position of the cam shaft illustrated in Figure 2 the valve to the soft water discharge pipe is closed but thro-ugh action of the cam 95 the valve in the chamber 22 is opened. Brine will therefore pass through the chamber 28, upwardly through the aperture 2S into the chamber 22 and thence downwardly into the chamber 30 from which it nows outwardly and downwardly through the drain pipe 59. After an ample -amount of brine has been introduced this operation is complete.

In the next regeneration phase of operation water is flushed through the mineral bed to wash out the brine. For this operation the hand wheel 1 is rotated to "regeneration position and in so the particles of the mineral substance.

doing the second face of the cam lifts the valve opposite secondary chamber 26 again to open position. Again fresh hard water from the pipe 24y flows through the chamber 2G into the chamber 26 and thence outwardly through the branch line 53 and pipe 5l] into the top of the mineral tank. This fresh water then passes down through the mineral bed washingY out the brine and emerges at the bottom from which it is conducted through the pipe 58 into the chamber 28 thence upward through the aperture 29 into the chamber 22. In this position a second face on the cam has lifted the valve in cham ber 22 to open position thereby permitting the water used in washing out the brine to pass into the chamber 3@ from which it is discharged outwardly through the drain pipe 59. This continues until all salt brine has been washed out of the mineral bed.

In order to provide a backwash operation the hand Wheel is rotated to a backwash position which sets the cams and valves in the relative positions indicated in Figure 4 of the drawings. As there shown cam 93 has been rotated so that the cam face lifts the third valve from the left in primary chamber 2G to open position. By the same operation cam 95 lifts the valve in chamber 23 to open position, all ofthe remaining valves being automatically closed by spring action. With the valves thus set fresh hard water from the supply pipe 2li passes into the chamber 2] and thence downwardly into the secondary chamber 28 and thence outwardly through the pipe 58 into the bottom of the mineral tank. The fresh water supply being under line pressure water is forced upwardly through the bed of mineral in the softening tank thus loosening up During this phase of operation the water passes upwardly and outwardly through the pipe 555 which communicates between the top of the mineral tank and the valve casing. Water which passes through the pipe 5i? is then routed through the branch line 511 into the primary chamber 23. No water passes through the branch line 53 because the valve opposite chamber 25 is in closed position as shown in Figure 4.

Backwashing water which iiows into the chamber 23 as just described passes downwardly into the chamber 32 and thence outwardly through the drain pipe 59. After this operation has been completed the hand wheel is rotated to the original soft-operating position and the Water softening device then proceeds to operate as described in connection with Figure l so that the fresh hard Water supply is softened and passed again to the point of consumption.

rihere has thus been provided a compact unitary multiple control valve wherein certain valve chambers serve a double or triple purpose. .All of the moving parts are contained within the valve casing so that extra packing for moving parts is reduced substantially to a minimum. The valve parts including removable seats have been kept to a uniform size, are easily accessible by removal of the cover plate and can be readily taken out and replaced. With this novel arrangement of valve elements operation of the device is further facilitated by having brine in.

the brine tank placed under pressure present in the supply line for the brining operation so that the device is positive acting during this phase of operation.

Some changes may be made in the construc tion and arrangement of the parts of my device without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims any modified forms of structure, or use of mechanical equivalents, which may be reasonably included within their scope.
