11 Claims.
This application is a continuation-in-part ofmy copending application for Lawn sprinkler, Serial No. 188,368, filed February 2, 1938.
This invention relates generally to lawn sprin- Y v,so'ciated therewith and comprising awater supply pipe or conduitbeneath the surface of the ground and provided with intermittently spaced nozzles of the instant invention.
Figure 2 is a'vertlcal substantially cross sectional view of one `form of the nozzles illustrated in Figure l and embodying the present inven-v tion, a portion thereof being illustrated in elevation to more clearly disclose the structure.
s Figure 3 is a plan view of the nozzle shown in Figure 2. Y Y
Figure 4 isa horizontal cross sectional view,
" taken along the lines 4-4`of Figure V2, looking means rotatably associated with the casing provided with an axial bore which is preferably closed at one end and communicates with an elongated discharge aperture to permit the formation of a substantially fan-shaped spray; the means being provided with an orifice positioned adjacent the closed end communicating with the bore for the free passage of water thereto and the entire structurel being so arranged that upon a manipulation of the means in a rotative mano ner the quantity of water passing through the orifice may be denitely controlled.
Another feature of the invention is the pro-` Vision of an incined wall adjacent the juncture of the bore and discharge aperture so as to assist in creating a turbulence in the water and thereby cause the water to leave the discharge aperture in the form of a spray.
A further object of the invention is the provision of a nozzle in a sprinkler system comprising a casing having a frusto-conical aring opening, frusto-conical means positioned in and partially closing the opening, a diaphragm inter- Vposed between the ends of the casing being either movably or rigidly associated therewith and adjustably associated with the frusto-conical means to determine the quantity or tamount of water passing through the restricted`opening; vthe diaphragm having a plurality of apertures of diierent dimensions to. thereby., control the configuration of the pattern formed by the water discharged from the restricted opening.
Numerous other objects and features will, of course, become apparent from the succeeding detailed description of theinventionand from an inspection of the accompanying drawing which illustrates exemplied forms of the invention and wherein:
Figure 1 illustrates a plan view of a plot of ground having a stationary sprinkler system asin the direction of the arrows.V 1
Figure 5 is a vertical cross sectional View of `a modification of the nozzleY illustrated in Figure 2, a portion thereof being shown in elevation to more clearly' illustrate the associated parts.
Figure 6 is a horizontal sectional view, taken along the lines 6 6 of Figure 5, looking in the directionof the arrows. n
Referring now in detail to the drawing, wherein like reference characters designate like parts, and initially considering the construction illustrated in Figures l to 4, inclusive, a plot or seco tion of ground I, arranged to be sprayed or watered, has, imbedded or1positioned beneath thev surface thereof, a water Vfeed'or supply pipe' or conduit 2 of a permanent sprinklersystem which is in direct communication withv a source of water supply. The-supply pipe is illustrated as being convoluted in configuration, but it may be, .if desired, formed to follow any 4predetermined path.
Intermittently spaced or positioned at inter- Y vals along the suppl'ypipeV and in direct com-` munication therewith is a plurality of-sprayer heads or nozzles 3 which are preferably positioned in staggered relation` with one another so as to be, by this particular arrangement, capable of thoroughly spraying lor watering the entire area subjected thereto. Each sprayer head or nozzle 3 desirably comprises a body member, housing or casing 4 preferably of circularconfiguration in horizontal cross section and having one or the lower extremity thereof interiorly threaded to accommodate an` exteriorly threaded associated end or outlet 5 of the supply pipe -2. The upper or free end Vo f the casing is provided with a frusto-conical or outwardly flaring openmg s formingtno discharge opening ofthe oaswall to be engaged by the waterpassing theref over and, in this manner, assist in setting. up
turbulence inior agitata, the water in order to' permit it to be ejected from the discharge opening in the form of a spray.
Disposed axiallyof the casing is a movable meansvor tubular member 9 comprising a head Positioned circumferentially of the diaphragm is a plurality of pairs of circular apertures 20 and 2| forming communications between the` Watersupply and casing bore 1. Both of the apertures 20 and 2| are arranged in angular re'- lation with respect to one another and pref apertures of various diameters is a square or subportion III formed'with a frusto-concal outward- A ly facing surface l I positioned in the casing opening 6. The tubular member surface II is, in the position'illustrated, spaced from the associated frusta-conical casing surface toprovide a 'restricted Water outlet or discharge opening'therebetween, and by reason of this arrangement the water passing through the restricted opening is deflected outwardly and away from the nozzle. The tubular member head is provided adjacent the upper or outer extremity thereof with a milled circumambient protuberance I2 which presents a means whereby the tubular member may be manipulated to govern or control the size of the restricted discharge opening as Well as perform other functions which will be hereinafter more fully described.
Extending inwardly of thevnozzle from the I tubular member head is a stem I3 having' spaced exteriorly threaded endportions, the one or upper of which is turned into an interiorly threaded portion of the head to thereby permit the head` and stern to move or'bemoved as a unitary member. Another objectin forming the head and stem of the tubular member as separate elements or pieces is to afford the assembly of the nozzle, as it will be noted, by referring most particularly to Figure 2, that the stem is provided With an outstanding convolution I4 formed as adouble cone-shaped shoulder which is of stantially square pattern ultimately formed on4 the ground .by the water issuing from the re- 23 provided in the tubular portion head. Conspaced thereabove.
greater extent than the inner and associated extremity of the frusto-concal opening 6 of the cas-'- ing. The convolution I4 has oppositely facing inclined surfaces I5 and I6 formed thereon, the former of which is oppositely disposed and spaced from the seat 8 to form a passageway therebetween communicating with the restricted opening for the egress of the Water. It will be observed that upon a manipulation of the tubular member in a rotary fashion the inclined surface I5 will approach and ultimately engage the seat 8- to positively arrest the passage of water therebetween. The inclined surface I6 also presents a deflecting wall to assist in agitating the Water and directing it toward the wall or seat 8 to be further agitated before passing through the restricted discharge opening.
Positioned within the casing is a disk or diaphragm I'Iv bearing against `,or seated upon a peripheral shoulder I8 formed in the casing ad-J jacent the lower extremitythereof.` Additional means to retain-the diaphragm in bearing relation with the rshoulder is preferably excluded from the structure as this function is performed ically shaped deflecting walls 24 are formed at the juncture of the bore 22 and the elongated `opening so as to present a wall to be struck by the water before it enters the' elongated opening to thereby set up a spray-like eifect of the ejected Water. When the tubular member is in the position illustrated no Water can enter the bore 22, and all of the water passing through the nozzle is exhausted through the restricted discharge opening. However, if it is found desirable to completely change the substantially square pattern formed bythel water passing through the restricted discharge opening the tubular member is manipulated until the inclined surface I5 bears against the-seat 8 at which time orifices 25, positioned adjacent4 the lower extremity o f the bore 22and communicating therewith, will be moved out of thehorizontal plane of the diaphragm. to be positioned in a plane With the', tubular member in its last recited position thefstream of water will be arrested from passing through the restricted discharge opening and Willv'then enter the orifices 25, pass through the bore 2 2, strike the deflecting wall 24, and-be forced through the elongated opening 23 fan-shaped-to form arrectangular pattern. It will, ofcourse, be clearly understood that the tubular member may be so positioned to permit the water to pass through both the restricted discharge opening and the elongated opening to effect a substantially square .and a rectangular pattern and, in this manner,
assure a thorough dampening of the ground immediately adjacent the nozzle as well as that portion of the ground removed therefrom.
Considering now the modification illustrated in Figures 5 and 6 of the drawing, wherein a simplied form of the nozzle is shown which retains some of the advantages and features of the A previously described structure, the nozzle is inby the force of the water acting ina vertical direction against the disk. i The` diaphragm is preferably rotatably associated vwith respect to the tubular member stem so as to lprovide a commodating the lowerextremity of the stem.
dicated generallyl by means of thev reference character 3 and comprises, in thelmain, a housing creasing 4"*I having adjacent the lower extremity thereof an interiorly threaded portion toxaccommodate an'd engage an associated end or outlet .'ia of a water supply pipe'orcondult 2a.
tutedfor any or all of thenozzles 3 inthe ar- Way inwardly of the casing. .Positioned intermediate the ends of the casingis an integrally formed disk, walll or diaphragm I'Ia defining-the Itwill, of course, be clearly understood that Y the nozzle 3** may be, if found desirable, substiinner extremity of the bore le. Circumferentially positioned pairs of circular apertures and 2I form communications between the feed or water supply pipe 2 and the bore 1a; the apertures 20'L beingV desirably spaced ninety `degrees apart and being of greater diameter than `the apertures 2|'i which are positioned between the apertures 20, reference beinghad to Figure 6 lof the drawing. This nozzle likewise is arranged and constructed todistribute Vor control the Water passing therethrough to have the water ultimately form a pattern of square or substantially square configuration upon the ad- "jacent ground. l.

By this arrangement, therefore, the water passing through the apertures Il and 21 will strike the wall I6* to create a turbulence '-or disturbance therein and continue upwardly through the bore 'la and ultimately through the restricted discharge opening in the form of a spray or mist. In order to maintain the movable means 9a in a predetermined position vertically of the nozzle, the head portion is provided with a downwardly extending stern exteriorly .threaded and projecting through a correspondingly threaded axially disposed hole I9a in the diaphragm. By manipulating the movable means in a rotative direction either clockwise or counter-clockwise, as viewed from the top, the extent of the restricted discharge opening may be d enitely governed. An outwardly facing moon-shaped indenture 26 is provided in the movable means head for the application or acopenings in said diaphragm. 2.
