2'Clai'ms. l
This invention relates to devices of those kinds known generally as spray nozzles. More particularly it has reference to improvements in spray nozzles designed for use in sprinkler systems that are like or similar to that disclosed and described in my co-pending application, filed on November 14, 1944, under Serial No. 563,330, now abandoned, which comprises a main water supply line from which branch pipes extend in various directions and at their outer ends are equipped with adjustable spray nozzles.
It is the principal object of this invention to provide an improved form of spray nozzle that may be used to great advantage in sprinkling systems where the character of the spray is important and where its direction of discharge may be required to be changed from time to time.
It is also an object of the invention to provide a spray nozzle with which a spray forming and spray deflecting plate of novel character is adjustably associated, and which, by an angular adjustment thereof relative to the direction of discharge of water from the nozzle, will change the degree of fineness of the spray, and by rotative adjustment about the nozzle axis, will effect change in the general direction of discharge of the spray.
It is a further object of myinvention to provide means for easily effecting and retaining changes in adjustment or position of the spray forming plate.
Yet another object is to provide means directly associated with the nozzle for controlling the volume of water delivered therethrough.
In accomplishing the above mentioned and other objects of the invention, I have provided the improved details of connection, the preferred forms of which are illustrated in the accompanying drawings, wherein Fig. 1 is a side view of a spray nozzle embodied by the present invention; showing it as applied to a water supply pipe.
Fig. 2 is an elevation of the nozzle as seen from the discharge end, with parts set asin Fig. 1.
Fig. 3 is a cross-sectional detail on line 3-3 in Fig. 1.
Fig. 4 is a somewhat enlarged top view of the spray nozzle.
Fig. 5 is a longitudinal section taken on line 55 in Fig. 4.
Referring more in detail to the drawings In its preferred form of construction the present spray nozzle comprises a metal body portion Ill, generally round in cross section, and formed longitudinally with awater channel II which at one end is counterbored and threaded, as at l2, for mounting the nozzle on a water supply pipe, or the like, as, shown;- the pipe being designated by reference numeral l3. At the .dischargeend of the nozzle, the passage H is reduced in diameter, as shown best in Fig. 5, to give greater velocity to the streamas discharged.
Formed in the body Iii, transversely of .the channel I l andpassing through it, is a bore It in which a valve 16 is rotatably fitted. The valve has a passage ll therethrough that may be brought into and from registration with the passage II to control the flow of water. The valve has a stem portion 16:; that is threaded into the bore. IE, to hold the valve in place, and at its outer end the stem is equipped with a knurled nut 20 for the rotatable adjustment of the valve.
The plate designed to form and determinethe direction and character of the spray, is designated in its entirety by reference numeral 25. It comprises a flat plate of metal, substantiallytriangular in form, as shown in Fig. 4, and equipped at the base of the triangle with a supporting arm 26. The plate is supported by a. collar 21 thatis fitted for rotation about the round outer end portion of the nozzle body; the collar, as noted in Fig. 3, being formed with two circumferentially spaced wings 2828 between which the arm 26 extends and through which wings and arm. a pin 29 is extended to pivotally mount the arm.
To retain the collar against displacement from the body l0, it is formed with an integral arm 30 that extends from between the wings toward the mounting end of the body as best shown in Fig. 5. Formed in this arm is a hole 3! in which a ball bearing 32 is fitted. The ball engages in a groove or channel 33 that encircles the nozzle body, and is held in the groove by a coiled spring 35 that bears at one end against the balland at its other end bears against the under side of the inner end portion of the arm 26. The spring thus has the dual purpose of holding the ball bearing in place and also holds the arm 26 and plate 25' in a set position of adjustment.
It will be understood by reference to Figs- 4 and 5, that the arm 26 is so attached to the collar that the fiat under surface of the. plate 25 will normally be disposed in the line of delivery of water from the nozzle as seen in Fig. 1, and by reason of its angular position will causethe water to be deflected therefrom as spray. The character of the water'spray and the angle ofv spread to opposite sides of the nozzle may be changedby changing the angle of the plate 25 relative to. the line of delivery, and the direction of delivery of spray can be changed by adjustingthe collar 21 and plate'25 about the axial line of the nozzle. For example, with the plate 25 set as. in Fig. 1, the spray will be directed downwardly and. for wardly- If thecollar 21 should berotatedin either direction, the. spray would be directed -laterally in accordance with the direction and extent of the adjustment. Likewise, if the plate 25 should be adjusted by turning the collar through 180, then the spray would be directed upwardly.
To change the angular adjustment of the plate 25, I have applied an adjusting screw 40 directly through the arm 26, forwardly of the pivot pin 29. This screw bears at its inner end against the conically tapered end surface of the nozzle body. At its outer end the screw is equipped with a knurled turning nut 41. By an inward or outward rotary adjustment of this screw 40, the plate 25 will be raised or lowered accordingly, as from the full line to the dotted line position shown in Fig. 5, thus to control the spread of the spray as well as its character or degree of fineness.
To use the device,'it is fixedly mounted on the water supply pipe l3 as shown. The pipe 13 may beheld in fixed position by any suitable means. The water supplied by pipe I3 is turned on by opening the valve 15, and volume flow may be regulated by rotatable adjustment of the valve between open and closed positions. The direction of delivery of spray from the nozzle is determined by the rotatable adjustment of the plate 25 about the axial line of the spray body. Rotation is efiected merely by grasping the collar and turning it about the body. The pressure of spring 35 against ball 32 retains the collar at a set position. The character of the spray produced, and its spread, is regulated b the angular adjustment of the plate 25, accomplished by turning the adjusting screw 40. r
' One of-the features of the invention resides in providing the spray plate 25 with a flange 59 across its base end, and projecting below the plane of the bottom surface of the plate, as seenin Figs. 1 and 2. This flange has a cut-out or recess 52 in alignment-with the water stream, as shown in Fig. 2, so as not to interfere with the water delivery or nozzle adjustment. The particular advantage of this flange is that it prevents backward delivery of spray from the plate 25, particularly when nozzle adjustments are being made. The flange also confines the maximum spread of spray to a definite angle. It has'been found desirable to form the plate 25 with a rounded nose as shown in Fig. 4, and to incline the opposite end portions of the flange 5B forwardly from the central recessed portion.
The particular advantages of a spray nozzle of this kind are that the angular spread of the spray can be regulated; the angular deflection can be changed to meet conditions, and the direction of delivery can be changed through a complete circle about the axis of delivery. The device is especially useful in spraying or sprinkling systems where a plurality of nozzles are grouped to cover a designated area in which some spots or parts ma require more or less water or finer spray than others. Spray nozzles of this kind may be made in various sizes, to meet requirements, and of various materials. They are especially useful in sprinkler systems made according to the disclosures of my previously mentioned application.
Having thus described my invention, what we claim as new therein and desire to secure by Letters Patent is 1. A'spray nozzle of the character described com-prising a body formed with a longitudinal channel counterbored and threaded at one end for fixedly mounting-the nozzle one water sup- 4 ply pipe for discharge of water through the nozzle channel; said body having a cylindrically formed outer end portion terminating in a conicallytapered end surface, and formed at a distance spaced from its end with an encircling channel, a collar fitted to the cylindrically formed portion for rotatable adjustment thereabout, said collar having an arm extended inwardly therefrom across said annular channel and equipped with a circular hole therethrough, spaced outwardly extending ears on the collar, 2. flat spray forming and deflecting plate formed with a mounting lever arm extended therefrom between said spaced ears and over said hole equipped arm, a pivot pin mounting said lever arm between said ears to adjustably support said plate angularly across the path of delivery of water from the nozzle, a ball bearing fitted in said circular hole to follow in the body encircling channel, a c'oiledspring disposed under compressio to bear against said balland said lever arm at the inside of its pivotal mounting, and a thumb screw threaded through said lever arm at the outside of its pivotal mounting and engaged against said conical surface and adjustable to change the angular disposition of the plate relative to the line of delivery of water from the nozzle.
