To all whom it may concern;-

Be it known that I, CHARLES L. WVInKiN's,

citizen ofthe United States, residing at Peoria, in the county of Peoria andstate of Illinois, have invented certain new and useful Improvements in lVatenSirp'ply Sys terns; and I do herebykdeclare'that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it apper;

tains to make and use the same.

This invention relates to improvements in water supply systems. It pertains more particularly to means for automatically controlling water elevating mechanisms in water supply systems in houses or wherever adaptedto supply water at distant points. 7

The invention pertains still more particularly to a valve arrangement on awwater lift or motor for directing the flow of motor-actuating pressure-water around, or

through the said lift or motor as occasion demands, said valve arrangement being applicable alike to all of the duplex or the single cylindertype.

The system provides for a supply of water T for dwellings, for example, furnished. from diflerent sources such as from city pressure service pipes or mams, and from cisterns or other sources of water not under pressure in which the servlce water from said clty servlce pipes or mains, which raises or forces the cistern water to astorage tank and in which, also, the pressure-waterfor actuating said water-lift whensubstan 'tially equalled by and overcomefby pressure in such tank,

will be shunted around the said lift without operatingit. 1

The object of my invention is to provide means for shunting the operating water-l pressure of the city mains around the water lift and combine such means with the'lift or pump whereby both can be made in a single part or unit readyfor installation.

A further object is to provide a pressure regulating mechanism in a water system of the class described for shunting the driving pressure for the pump around the driving member or motor which will ble to sudden changes in service pressure, all of which will accompanying description aided by the drawings forming a part of this application and in which; u 1

Figure 1 is somewhat in the nature of a styles or makes whether is utilized to actuate a water-lift of any desired type,

Fig. 3 is a vertical, transverse=section of the regulator on line Fig. 2showing a part of the water'motor with which it is associated, and-Fig4 4, is a horizontal section of a part of the said r es I have illustrated the manner of'instal; ling the lift or motor in a water system and the valve for directing the water pressure for said motor. Cheapness of construction,

simplicity, I andfew number of parts are of importance. as well as compactness of the devlce andthe ease of f installat on. over known ways, not losing sight of an mpor tant point-that of building a lift or motor and directing valve in a complete single l atented J an. 23, i912,

I desire to state that I am fully aware that it is not new to provide a regulatorfor shunting the operating pressure around "a motor after storing up tank-pressure, but

my invention relates more particularly to with a motor and combininga regulator Y I pump and especially a regulator of the peculiar'type to be described herein,.or its equivalent, whereby as stated in the objects,

stalled, thereby, simplifying the work of installation and enabling me to produce a system at a much lower cost than heretofore. and having, advantages of structure and operation also as will appear herein.

A indicates a tank into which cistern or particularly,

in one part can be inother water is introduced under pressure through a pipe B by means of anyfsui-table pump C from a pipe D connected into cistern or other source of. soft water.

E represents a motor driven by waterv pressure from a city main, for through alpipe F. and a lateral G connected therewith ,1 my improved regulator being interposed between the said lateral Gandthe.

motor and represented as a whole by'the letter H. v

J is a pipe connected into the tank A for supplying the fixtures at various .remote example,

places with softwater; one of-the said. fixtures being indicatedby a faucet or cook said dome to the K, said pipe J also having connections if desired with the service pipe F in the customary manner, there being a normally closed valve or cut-ofif L interposed between the two. The motor E has a service *pipe M connected to it to receive both the water discharged from said motor and the direct city pressure when the motor is not in operation as will appear presently and through which other fixtures, one of which is indicated at N, for example, may be supplied with water from said city pressure or other source operating said motor.

The pump and motor are combined as is customary in such devices whereby by means of a piston, for example, not shown, the water being raised through the pipe D is forced through the pipe B into the said tank A.

The internal mechanism of the motor and pump will not be dealt with since these are old and well known and require no description herein the invention pertaining, as already stated, to the regulator now to be described.

Mounted upon the valve-cylinder O of the motor E is the small cylinder H already referred to which is provided with a bore Q. At one end it has a flared or coned extension R provided with a cavity S arranged to receive a coned hollow cap T, there being interposed between these two parts a diaphragm U of any suitable material having the desired thickness. One end of a pipe V is connected into the said cap T and its other end is connected into a dome W of the pump; this said pipe V having a free and uninterrupted connection through pipe B. A plug 2 is screwed into the end of the cylinder H at its end opposite that having the diaphragm and though this plugmay be a part of the cylinder if desired, for convenience I make it removable. It is provided with a bore 3 communicating at its inner end with the bore of the cylinder while its outer end is threaded to receive a screw plug 4. A cap 5 forming a stufiing box is screwed upon the end of the plug 2 and has a packing 6 to preventleakage of water around and past said screw plug 4. The latter member is provided with a socket 7 to receive one end of the valve-stem 8, the other end of the latter being carried by and slidable within a screw-plug 9 held in the bore of the cylinder adjacent to the diaphragmchamber S, as clearly shown in Fig. 2, a packing S preventing leakage of water toward and upon said diaphragm. The valve-stem at this end carries an abutment 10 to lie against the diaphragm as shown. The valve carried by the stem is indicated at 12 and has a disk 18 of suitable material lying at each side constituting packing members. ll ithin the bore Q of the cylinder and facing one another are extensions 14 and 15 forming valve-seats, the disks 13 on the said valve adapted to seat on one or the other of them depending upon the conditions existing within the system; but this will be made clear hereinafter. The distance between the seats 14 and 15 is greater than the distance between the said disks 18, however, so that when the valve is seated on. one of the extensions 14, 15 a free passage exists between the valve and'the opposite extension.

Interposed between the screw-plug 4 and the valve 12 is an expansion spring 8 preferably carried by the valve-stem, as shown, and the pressure of this spring holds the valve normally upon the seat 14. Connecting with the bore Q, is a passage 16 which leads to the exhaust pipe M beneath the cylinder in any of the usual ways, in this case being extended through an enlargement 17 at the side of the motor, Figs. 3 and 4, to discharge into the valve cylinder O from which it finds its way to the pipe M, but any other disposition of the water carried through said passage 16 may be made so long as it may finally preferably discharge into the said pipe M since therefrom it may be drawn under pressure through any fixture as N, for example, already referred to. As it is the desire to supply city water throughout the system for various uses where soft water is not needed it is better to take it from this source rather than from the pressure pipes F G, direct, since to do the latter would cause the motor-pressure to be variable which is not desirable. At 18 is a passage leading from the bore of the plug 2 into the said valve cylinder 0, the water introduced through this passage serving to drive the motor.

The operation of the system and the regulator will be understood from the following:The city or other pressure for operat ing the motor enters the regulator through the pipes F and G, the spring 8 exerting its pressure to hold the valve 12 upon the seat 14 with the result that the water entering the regulator passes the said valve 12 and enters the bore 3 and passage 18 into the valve cylinder 0 where it is properly discharged into the cylinder E to drive the motor and from which it then passes into the pipe M, the valve N connected with the pipe M being opened to allow free discharge of the water pressure as the motor in operating the pump introduces the water into the tank A. As water is pumped into said tank the air contained in the latter is compressed to any desired extent the water being thereby under pressure sufficient to force it to remote fixtures. Now let it be supposed that the air pressure in the tank is to be held at 50 pounds. The motor remains in operation until this pressure has been reached and at this point the back pressure from easily overcome the spring 8 and the prespressure in the tank.

said tank through the pipe B, 'dome W,

and pipe V, acts upon the diaphragm U to overcome the pressure" which drives, the motor. This back-pressure in beingplaced upon the diaphragm which is ofmuch greater area than the valve 12, is able to sure of water upon said valve at that side; The result is that said valve is forced against its spring; the bore 3 being closed by it thereby stopping the motor, the water" being shunted past the latter through the bore Q into the discharge pipe M. As the pressures from both sources are now practically in state of equilibrium the flow will be around the motor until a quantity ofsoft water is I time the pressure in said tank will relieve the pressure upon the soft water side of the diaphragm. The spring 8 then carries the valve 12 to its first position this being aided f more or less by the city pressure which is now being permitted to divide andpass by the valve toward the cylinder 0 exerting its force upon said valve. The 'motor is now once more in operation to restore the The pressure is substantially constant, within the pipe M since the water flows into' it at all times either through or around the motor although it may be slightly reduced, perhaps, in passing through the latter but it is never interrupted. It is seen that both i the water from the city mains and soft water from the pressure tank can bedrawn from their respectivefixtures.

My regulator is very simple in structure, operates directly in connection with the motor and pump and is absolutely positive in action. The adjustment of the screwplug 4 provides for imparting any'desired tension to the spring18 inorder to arrange for any desired pressure in the tank A since obviously the stronger the tension the. higher the pressure will beraised before the water of the city mains .is shunted around the motor. I

It is observed that vthe pressure in the pipe M is practically constant at, all times and sufficient to discharge from the fixture N since the water must pass into said pipe in either position ofthe valve 12, z. 6. whether the motor is in operation or not so that it is not required that the pipe through which the pressure flows should be directly connected into the pipe M as is customary in order to maintain a pressure 7 at the fixtures.

The regulation of the spring-tension also provides for the expansion of the air in the tank due to varying temperature in the room in which said tank is installed, that is to say, ,the spring may be setso'that the drawn from the tank A at which motor will be stopped when the pressure from the tank is a little less than the pressure that may obtainthereindue to the higher temperature 1 described. fore, the tank pressure is to be maximum, the: regulator is set forthat pressure less the estimatedexpansion.

i I have described and shown the tubular 1 extension or valve seat 15 through which the with the port water-pressure communicates If, ,there- 50 pounds" 18 of the motor and Ihave also shown one I of the disks 13 for seating thereon but itis to be stated that I may not use said valveseat and the valve need not be constructed so as to. close a passage at thatside of the valve at all, merely leaving a free passage betweenothe pipe G and. thesaid port 18. The spring 8 holds the'valve upon the seat 14; so that the pressure must normally pass against the tension of the said spring. Now,

into the motor but whenthe pressure inthe tank A equals or slightly more than equals. the city water-pressure, the valve is moved since the valve hasbeen opened the path of the least resistance for the city pressure: is naturally through the passage I6 rather than through the said. port 18 to drive the motor. This is stated inorder to make it funderstoodthat I am'not necessarily con-f finedto what hasbeen shown and described and I desire to state, also, that I may make ,such I other changes in my device as will suggest themselves and such as will fall within the meaning andintent of the invention and the claims. By having 'thesaid regulatora part of the said pump and motor it is only necessary to connect the pipes to it and the latter and the work of installation is complete as to" these portions, whereasin a system of which I am aware the pump and the regulator are separate and distinct'parts and require to beset up separately thus entailing considerable unnecessary work and expenditure of time. And in this connection it may be stated that I am aware'of a regu lator'which is not'mounted directly on the pump being, intact, a ,part of the pipe system and removed some distance 'from' 7 said pump and this regulator employs a diaphragm ctor operating a valve in the path 7 of the city water pressure but that pressure allowed to pass through-this reguis-only lator in one direction. When the valve is closed the water doesn'otfiow at all being merely interrupted in its movement toward said regulator and made to pass'oif through another part of thesystem or without entering said regulator.
