' Claims. (01. 137 -78) This invention relates to new-and useful immovements in automatic fluid, dispensing pp ratus and the primary object of. the present. invention is to provide a device that will cfficlcntly and automatically supply fluid to a dischar point without supervision. l, 7

Another important obiectoi the present inventlon is to provide a, .fluid dispensing apparatus that-includes electrical as Well as manual means whereby the fluid distributed may be controlled. A lurtherobject. of; the present. invention is to provide an automatic fluid dispensing apparatus including a time control mechanism whereby the flow of. fluid may be regulated for any length of time and at a s l c ed tim A still further aim or the present invention is to provide an apparatus for the foregoing purposes that is simple and practical in construction, cfilcient and reliable in operation, relatively inexpensive to manufacture. and otherwise well adapted tor the purposes for which the same is intended,

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings formin part-hereoi, wherein like numerals refer to like Parts throughout, and in which: I Figure. 1 is a fragmentary diagrammatic front elevational view of the present invention;

Figure. 2 is a fragmentary side elevational view ofthe distributor valve means;

Figurefl is. an' enlarged vertical sectional view taken, on the line 3-4 of Figure Figure. 4 is a perspective view of the humidity control mechanism; 7

. Figure 5 is a perspective-view of the control valve mounted in the distributor; and,

v Figure 6. is. a longitudinal vertical. sectional view taken on line 6--6 of Figure 5.

Referring now to the drawings in detail, wherein for the purpose of illustration, there is disclosed a preferred embodiment of the present invention, the numeral l0 represents asupport onwhich is mounted a distributor housing I2 having a pair of removable end plates l4.

Extending substantially through the center of the housing and journaled in bearings l6 carried by the hub portion 18 provided at the outer faces ofplates |4, is a drive shaft 20. v

Mounted on shaft 20 within housing It is the hub 2| of a rotary disc-like valve member 22, provided with an arcuate slot 24 in its. flanged portion 26, that selectively communicates with a plurality of outlet mains 28 carried by .the

distributor housing l.2.. I v

plurality of circumferentially spaced apertures 30 are also provided in member 22 to prevent entering pressure from looking member 22 Qperatively connected to shaft 20. by a clutch mechanism 32, is a speed reduction gear mechanismdesignated generally by the numeral 34, that is operated by an electric motor36. The clutch mechanism permits the gear mechanism 34 to rotate the shaft 20 in one direction only.

Av supply main 38 for the distributor is interposed between the distributor and a source or fluid for supplying fluid to the distributor. This main 3B is provided withv an air buoy or stack 40 closed by removablecap 42 that tends to prevent water hammer in the main 38., v

Mounted in the fluid supply main 38 is a sol'enoid operating valve 44 that is connected'by' electrical lines 48 to a, source of electric power for operating the valve in closing and opening the supply main 38.

A by-pass 48 around valve 44 includes a 'manually operated valve 50 for manually regulating the flow of fluid from the main 38 to the distributor-housing.

Mounted in series with the solenoid valve 44 is a time control mechanism 52 for controlling said valve 44. This time control mechanismis also connected in series to motor36 for simultaneously controlling the operating period'ior said motor and the opening period for valve 44.

Connected in series to the time control mechanism is a mercury control mechanism designated generally by the numeral 54. This mercury control mechanism or humidifier 54 includes a canvas belt 56 interlaced with pegs 58 carried byvan anchor'plate 60. One end of the belt is secured to a housing 62 carried by the plate at one end and the other end of belt 56 is connected to'a coll spring 64 mounted within housing 62. The tension of said spring 54 is adjustable by set screws or the like 66. I

Pivotally mounted within the housing 6 is a mercury tube 68 provided with-an outwardly pro.- jecting' arm in, that is suitably connected to the spring 64 adjacent the end of belt 56, A stonand support 12 carried by the housing supports the lower end of tube 68 when the electrical circuit to the housing and thus these apertures also per- 60 mit a, smooth undisturbed rotation of the valve.

System is open and limits Pivotal movement of the tube within the housing. v In practical use of the device the humidifier 54 is mounted outdoors and when the'weather conditions are dry,v the canvas belt is contracted to over-balance the spring 64 causing the mercury tube to tilt toward the belt and closing the cirone of the outlet mains 28 for causing a time.

regulated flow of fluid through said outlet main.

As the valve continues rotation, opening 24 then communicates with another of said mains28 for likewise controlling the time now through the mains. However, as previously stated should the atmospheric condition be wet, the humidity cone trol mechanism will automatically cut oil the solenoid valve 44 so that water or fluid will not be wasted for sprinkling a lawn or the like.

1701' manual use of the device, the valve' 5ll is turnedon and by rotating shaft 20 by hand wheel 74, the flow of fluid through the outlet mains 28 maybe selectively controlled.

Obviously, clutch 32 is disengaged with the gear mechanism 34 so thatthe shaft ZOm'ay be conveniently rotated manually without devolving thegear mechanism. 4

In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the construction, operation and advantages of "the device will be quiteapparent to those skilled. in this art. .Amore detailed descriptionv is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention the same is susceptible to certain changes fully comprehended by the spirit of the invention as,- herein described and the scope of theappended qlaims.
