(Cl. 10S-207) 3 Claims.

This case is a substitute for abandoned patent application of Ralph W. Tilsy for an improved Farm fresh water system, Serial No. 195,096,1led March 10, 1938.

This invention relates to improvements in rural water supply systems and especially is concerned with a novel device for controlling fluid supplied by a windmill operated pump whereby the pressure of fluids so supplied is maintained substantially constant despite drain of the fluid supply.

The novel device according to the instant invention is of especial application to rural uses wherein a wind driven pump serves normally to provide the establishment with water for at least a majority of its uses but wherein occasionally relatively large drains of the water supply are made which indicate a necessity for auxiliary pumping means to satisfy the occasional or periodic abnormal requirements.

A feature of the novel pumping system according to the instant invention is that it includes means sensitive to change of pressure in the uid transmission network fed by the wind driven pump whereby an auxiliary power driven unit is automatically coupled with the vpumping system for operating same.

It is an object therefore of `this invention to provide the aforesaid type of fluid pressure sensitive means for automatically coupling a fluid supply pump with an auxiliary power source.

A feature of the novel device according to this invention is that although the pump may operate constantly to supply fluid both for use and for storage, the actuation of the pressure sensitive means serves, in addition to accomplishing the above mentioned effects, to stop shuto and terminate the supply of fluid to the storage tank, thereby assuring maximum flow of fluid to those places where fluid is being used.

An important advantage of the novel fluid supply system according to the instant invention is that the elements thereof are structurally relatively simple and, being largely uniform or standard parts, are readily available on the market or can easily be manufactured under conditions of mass production, thereby minimizing the initial cost of the device. The structural simplicity of the device also is important in that thereby is minimized the cost of upkeep and/or of repair.

Other objects, advantages and features of the new and improved pumping system according Yto the present invention will beapparent to those skilled in this art during the course of the following` description.

Regarded in certain of its broader aspects the into coupled relation thereto feeding a fluid transmission network, of means sensitive to fluid kpressure in said network for, upon occasion, un-

the said means comprising a pressure sensitive motor unit, a horizontally sliding key carried on said'pump shaft separately engaging key ways formed in said bar and said mill head and operable by said motor for moving said key from the spring urged coupled relation causing engagement with said bar.

In order to facilitate a fuller and more complete understanding of the present invention, a specific embodiment thereof herein illustrated will be hereinafter described, it being clearly understood, however, that the illustrated embodiment, although presently preferred, is provided solely by Way of example of the practice of this invention and not by way of limitation thereof except insofar as the invention is recited in the subjoined claims.

Referring then to thedrawings,

Fig.V 8 is a sectional view of a three-way valve forming partof the device according to this invention.

Referring now to the drawings for la description of the illustrated preferred embodiment of this invention, it will be noted that a windmill generally designated by the reference character A and having a vertically reciprocating mill head i!) terminating within a cage H supported on the frame Il is coupled by means, which will be hereinafter described, to the drive shaft of a pump l21 located in the pump well substantially as shown, it being noted of course that the pump shaft is designatedv by the reference character I3, the end of the pump shaft extending upwardly and also being received within the cage generally designated by the reference character ll.

Referring now especially to Figs. 2 and 3' it will be noted that the cage II comprises a pair of spaced parallel -plates IIa and IIb held in fixed relation by cross members IIc and IId, four of which are provided, two on each end of the plates attached thereto by fastening means Ile, II ,f and IIg. Between the cross pieces IIc and I Id the end portions of the mill head I Il and of the pump Vshaft I3 are received, being freely slidable with respect to each other. The means for coupling the mill head and pump shaft will subsequently be described, but for present purposes it is to be understood that upon occasion, as will hereinafter appear, these members can be coupled. It will be perceived from Fig. 1 that the pump shaft I3 is normally urged upwardly by a collar I4 attached thereto against which spring-pressing means I5, sleeved around the shaft, acts.

Fluid from the pump I2 passes to the line I6 from whence it is conveyed to an appropriate storage tank, it being noted that the flow of fluid in the line I6 is controlled by a valve generally designated by the reference character I'I, details of which are best illustrated in Figs. 6 and 7. VIt will be noted that the valve I'I comprises a casing I'Ia which is essentially T-shaped and includes an internal partition provided with a valve seat Il'b extending therethrough against which may rest a valve member I'Ic carried on a sliding rod lIcZl mounted in the plug Ila' and normally pressed into open position by the spring I'Ie sleeved around the rod IId and acting against portions of the plug IIa' and the plate I'If mounted on the free end of the rod. The plate is provided with upwardly extending connector elements I'ig terminating in a loop I'Ih to which is connected a relatively ineXtensible cable lIIc operable as hereinafter will be described.

Fluid from the pump I2 passes as above described through the line I6 and also, upon occasion, may pass through the check valve I9, relief valve 23 and hydraulic cushion 2| to the feed line 22 communicating with the pipe line 23 which is connected to a supply faucet 24, the last mentioned being conveniently located in a locality where water is used. Upon occasion a portion of the fluid in the line 22 passes through the check valve 25 to the pipe line 26 from whence the iiuid passes tothe storage tank or so-called pressure tank 27 preferably located in the top of the building being supplied or at least in a relatively raised position. A line 28 connected to the line 22 and terminating in a faucet 29 is useful for providing fluid to be used in the vicinity of the pump and on this line also are provided a pressure vgauge 30 and a pressure sensitiveelectrical switch 3|. It is to be understood that the switch 3| is sensitive to and operable by `changes in pressure'of the fluid in the several pipe lines connected to the line 22 and, accordingly, that the switch can, upon occasion, be operated by opening of the faucet 24 whereby the pressure in the mentioned lines is diminished.

The switch 3l above described .controls the current supply of a motor 32 whereby diminution in pressure ofthe fluid in the mentioned pipe lines causes operationY ofthe switch and Vstarting of the motor. The motor shaft carries a pulley 33 which `is connected by the belt 34 witha transmission pulley 35 which in turn is lconnected with a governor 36 by a belt 31. As the speed of -rotation of the governor 36 increases, tension is exerted in the lineY 38 connected thereto causing operation of-a valve generally designated by the perpendicularly positioned opening 39e.

40 to the pipe 40'. Reference is made to Fig. 8 wherein details of the valve 39 best are illustrated and from which it will be noted the valve comprises a casing member 39a within which is positioned a rotatable valve member 39h having a diametrically extending opening 35e formed therein communicating with a radially extending It will be seenthat the valve casing 39a is provided with three spaced

openings

39d and 39e and 33j registerable upon occasion with

openings

39e and 39e of the valve member 39h. The valve member numeral 39 controlling iiow of duid from the pipe 75 normally is held in the position illustrated in Fig. 8 by spring tensioning means 35g, but the valve may be swung through approximately an arc of a right angle by tensioning of the cable 38 as above mentioned. It will be noted that in the normal position of the valve the pipe line 40 is in communication with the atmosphere through the opening 39e of the valve casing, but when the valve member is moved as aforesaid, the pipe lines 40 and 4U' communicate. i The pipe line 4l] is connected to a fluid storage chamber 4I provided with a relief valve 42 which, in turn, is connected by the pipe line 43 with a compressor 44 driven by the eccentric 45 connected by the belt 46 to the differential pulley 35 which, it will be recalled, is driven by the motor 32 as above described. The operation of the motor causes operation of the compressor 44 and provides an appreciable fluid pressure in the storage tank 4I and, accordingly, when the valve generally designated by the numeral 39 is opened, the fluid from the storage tank discharges through the pipe line 40 to the pipe line 40 which is connected to a piston chamber 4l wherein a piston 43 slides, thereby causing the piston to move which,in turn, acts through the piston rod 49 to cause counterclockwise rotative motion of the arm 50 which is pivotally mounted on parts of the frame II' and which is connected to the piston rod as shown. The counterclockwiserotation of the lever arm 53 tensions the spring 5I, thereby exerting a pulling action on the cable IIh, causing closing of the valve generally designated by the numeral I'I whereby the total output of the pump I2 is `directed into the pipe line4 i8.

Counter-clockwise motion of the lever arm 50 also tensions the spring 53 exerting pulling action on the cable 54 connected thereto which is connected in turn to a hooked end portion 555 of a sliding key 56.

Referring now especially to Figs. 2, 3, 4 and 5, it will benoted that the key generally designated by the numeral 55 comprises a central portion 5l and spaced parallel oppositely extending key elements` 58 and 59 formed thereon. Y Referring now to Fig. 4, it will be noted that a key-way Illa. is formed in a side portion of the mill head I0 to receive the key 5S and that a corresponding and registerable opening H30 is formed in the pump shaft I3. As will be evident `from consideration of the drawings, the upper end of the pump shaft I3 is split and the portion I3a thereof is attached to the main body ofthe shaft I3 by appropriatefastening means ISD. This structure is provided to facilitate the sliding motion of the key 53 within a horizontally extending opening YIiidformed in the-shaft elements andextending across the interface. A cut-away portion I 3e formed in the shaft I 3 is provided to receive the key 55 for purposes which hereinafter more fully will be apparent.

It will be perceived that when the key 58 is positioned within the key-way I @a of the mill head.

I and the opening |30 formed in the pump shaft end portion, the mill head and pump shaft will be coupled whereby the reciprocating motion of the former will cause reciprocating motion of the latter, whereby the pump is operated. This is the normal condition and to facilitate continuous coupling of the mill head and the pump shaft under normal conditions, the end portions 51a. of the `key 58 is provided with a ball 6E? integrally formed therewith which is held in a socket formed in the end part la. of a coupling member 6|, but is held in position therein by a cap 65h substantially as is illustrated in Fig. 3. The opposite end of the coupling El is pierced to receive the pivot 52 carried in a yoke E3 mounted on an end portion of a rod 64 slidingly carried in an opening formed in the bracket 65 mounted on parts of the supporting frame. The rod is provided with a cap 66 on the end thereof against which acts a spring 61 serving normally to urge the rod outwardly assuring coupling of the mill head and pump shaft as hereinabove described.

A vertically freely reciprocal `bar 10 provided with a key-way 19d in a side thereof registerable with the opening 13e in the side of the pump shaft i3 is slidingly mounted in the cage generally designated by the numeral I l and carries attached thereto by a fastening means 1! a horizontally extending bracket 12 which is provided with an opening in the` distal end part thereof to receive the rod 13 carried upon the vertically reciprocable frame 14, the end portion 14a of which is freely slidingly mounted in the bracket 15 attached to parts of the frame il. The frame 1d is reciprocated by the wheel 16 driven `by the motor 32 whereby, when the motor is in operation, the frame 14 continuously reciprocates, thereby causing vertical reciprocation of the bar 1li.

When, as hereinabove described, the cable 54 is tensioned by counter-clockwise rotation of the arm 50, the key generally designated by the numeral 56 is moved against the pressing action of the spring 61 whereby the key element 59 is positioned in the openings 13e of the pump shaft i3 and the keyf-way 10c of the bar 1Q, thereby operatively coupling the pump shaft and reciprocating bar. It will be evident of course that when the bar and shaft are so coupled, the key element 58 .becomes disengaged from the mill head whereby operation of the pump shaft by the motor through the reciprocating bar is permitted.

Experience indicates that frequently the locking of the key element 58 in engagement with the mill head and pump shaft is such as to make difficult disengagement by tensioning the cable 54 and, accordingly, a small hammer lever 11 tensioned against the head 5S of the rod t4 by means of the spring i8 is provided for facilitating the disengagement and for augmenting the I force applied to the key 56 by tensioning the cable 54. The hammer arm 11, which is pivotally mounted on a bracket 11a, is operable from the shaft to the compressor eccentric 45 by conventional means not illustrated.

lt will be evident from the foregoing that in operation the device according to the present invention provides means for bypassing flow of fluid from a pump driven by a windmill whereby discharge of the fiuid to a storage tank is prevented and whereby maintenance of fluid in a transmission network is assured. It will be apparent from the foregoing that lowering of fluid pressure in the transmission lines causes operation of the pressure sensitive switch whereby the pump is disengaged from the windmill and is operated preferably at a higher speed by electric power. It of course will be understood that instead of the electric motor above described, other types of motors can be used, such as gas engine, steam engine, or the like.`

It is to be understood of course that this invention is capable of extended application and is not confined to the precise illustrated forms nor described construction and, therefore, such changes and modifications may be made therein as do not affect the spirit of the invention nor exceed the scope of the appended claims.
