UNITED STATES PATENT OFFICE.

DONALD ELDER, OF ONEH'UNGA, NEW ZEALAND.

APPARATUS FOR WATERING AREAS OIF LAND.

Application filed January 5, 1922, Serial No. 527,259, and in New Zealand November 8, 1920.

This invention relates to means employed in watering areas ot land and has for its object the provision ol improved sprayer whereby areas ot land of any shape can be watered evenly and thoroughly.

The. sprayer comprises a casing containing a turbine, carried by a hollow fitting and capable oit revolving about a vertical pipe preferably fixedto a stand or base and adapted to be connected with the Water discharge outlet of a regulator of the type disclosed in my co-pending application, Se-

rial Number 577,266 ,tiled July 24, 1922.

The water passes from the vertical pipe through the hollow fitting and the casing to an outlet provided with a nozzle. In passing through the casing, the water drives the turbine, the shaft ot which is geared with a stationary worm wheel on the vertical pipe or on a fitting thereon, whereby the turbine is utilized to give 'rotary motion to the sprayer about the vertical pipe. The rot-ary motion can be continuous in the one direc tion or be suoli that the sprayer will make a 'full revolution ilrstin one direction and then a tull revolution in the reverse direction. or said sprayer can be caused to operate backwards and forwards through any desired portion o't a circle.

In order to accommodate the sprayer or rather the jet ot water from same to arcas having irregularoutlines or boundaries, a nozzle containing a cocl is employed the discharge et said nozzle having projecting therefrom a rigid arm kept in contact with a stationary regulating plate on the upper end ot the vertical pipe. This plate is given a shape or outline which corresponds with that ot the area oit land to be watered. As the sprayer rotates about the vertical pipe, the arm ot' lthe nozzle is dragged along the edge ot the regulating plate and rides over the projections on and enters the depressions in the latter, whereby the discharge end ot' the nozzle is raised and lowered to regulate the throw ot' water to the outline ot the area, and also to regulate the volume ot water issuing from the nozzle.

he invention will now be more particularly described in conjunction with the aocompanying Adrawings wherein ,Figure 1 is an elevation (broken) of the sprayer. l

Figure 2 is a plan view ot same.

Figure 3 is a sectional plan view taken on the line A--A, Figure 1.

Figure 41 is an inverted plan view of portion ot the reversing clutch actuating mechanism.

Figure 5 is a part plan view showing the sprayer' constructed so as to rotate cont-inuously in the one direction, while Figures 6 and 7 are a plan view and a cross sectional view respectively of the re versing clutch.

Figure 8 illustrates a plate for regulating the volume of water and the altitude of the stream of water when watering an area having a shape similar to that of the plate.

Referring to the drawing in detail the vertical pipe 105 which preferably is fitted in a suitable stand or base and receives water trom a regulator of the type disclosed in my copending application has screwed in its upper end a tube `106 closed at its upper end upon which is a vertical stud 106.

it hollow fitting 115 having in its upper end an opening'whieh fits the stud 106, and in its lower end an opening which fits the tube 106 is` rotatable about the latter, an annular space 107 being left around the tube 106.

The tube 106` contains one or more ports 108 which open into the annular space 107.

lVater from the pipe 105 passes through the tube 106, ports 108. and annular space 107 into the branch 109 which is connected 'with the inlet 110 ol" the casing 111, so that oi the regulating plate 116, held stationary` on the stud 106u at the upper end of the tube 106.

The plate 11G has an outline shaped to correspond with the outline of the area or the portion thereof to be watered and as the sprayer is rotated about the pipe 105, the arm 114 is forced by the spring 117 into any depressions or recesses there may be in the edge ot' the plate 116, the result ot which is that the mouthpiece 114a ot the nozzle v113 is depressed and causes the cock gull to reduce the volume water if' iinpj 'from the mouthpiece and at the saine time to shorten the throw i the water 'from the nozzle.

As the arm 1111v rides over any projection on the plate edge the mouthpiece 1141" ot the nozzle 113 is elevated which allows the volume o1 vater to be increased and causes the thro v et the water to be lengthened.

3y these ineans both the volume and the throw ot water from the nozzle 113 are renuiated at all times to keep within the linut ot the area being treated and to evenly waterl the whole area providing that a plate 11i having; an outline correspendingl with tl at ot he area being; treated is provided tor the aini 11e to work against.

The turbine contained in the casing` 111 comprises z vertical dise 118 having a boss or hub 118?L keyed on the shatt 119.

Projecting; at r' it angles iti-oui the f 118 and a short distance Ytrom the et thereof is a circular wall 120 whereby an annular space 121 surrounding the boss or hub 118a is provided.

:The turbine blades are litted to the disc 118 and circular wall, 120, outside the latter, said blades being` curved to meet the water entering)` the casing 111 through the inlet- 110.

Ports 123'tlirough the wall 120, between theblad open into the annular space 121 enabling water to enter the latter.

vWater o'i eircring the casing 111 through the inlet 11() fills the space 121 a'ttcr which incoming wat fr can only escape by way oit the outlet 112, and in doing so acts on the blades 122 and drives the turbine in the dircetion indicated by the arrow in Figure 1.

@nene end ot the turbine shaft 119 is keyed a worm 121i which drives a worni wheel 125 in turn keyed on one end ot a shatt 126 mounted in bearings on a bracket 2T carried by the casing 111.

0nthe other end oif this shaft 126 is keyed a bevel whee 12S which meshes with two bevel wheels 129, 130 loosely niounted on a shatt 131 supported in bearings on the b 'aclet 127, at right angles to the .hatt 126.

A clutch 132 feathered on the shatt 131 so to be slidable thereon but always rotatin` therewith provided at each end with teeth 132a and is oi? such i ,tengjgth hat when the teeth at one end e enjcagiei in corre sl'londi'iliy "formed teeth one oi he whrrlr; 129 130, the teeth at the other cud are clear ot siii'iilar teeth ou the other ot said wheelsI 129v St?.

ro t a d.

rEhe teeth 152n at one end ot the clutch 132 bcingr engaged in the teeth ot one of the wheels 129-130, the engaged wheel is locked on and drives the shaft 131, the effect of which is that the worm 133 working in the stationary worm wheel 134 causes the casing 111 and tting 115 with they parts carried thereon to travel around the pipe 105. If it is desired that the sprayer shall make a full vturn in one direction, and then a. full turn in the opposite direction, only one pin or peg 136 is placed in the wheel 134. When the clutch arm 138 strikes the pin or peg.

136 the vertical shaft 137 is given a partial turning movement and the clutch engaging arm 139 is moved towards the opposite end of the clutch 132 until it comes in contactV the clutch 132 from the wheel 129 or the wheel 130 the point of the arm 141 clears the point of the projection 142 whereupon the latter springs forward and acting against the side of the arm 141 gives further turning movement tothe vertical shaft 137,`

which results in the upper arm 1.39 forcing the clutch 132 into engagement with the opposite of the wheels 129-130 from which it was withdrawn, whereby the shaft 131 is caused to rotate in the reverse direction and the sprayer is caused to travel about the pipe in the reverse direction to which 1t didjust previously. y

TVhcn however the sprayer is required to operate backwards and forwards through a given portion of a circle, two pins or pegs 136 are used. These ai'e placed in the wheel 134 the necessary distance apart and each time the arm 138 strikes a. pin or peg 136, a reversal of the travel of the sprayer about the pipe is effected.

The sprayer' constructed as shown inthe drawing can be caused to rotate continuously in the onedirection by locking the clutch 132 in whichever of the wheels 129-130 it is desired and not inserting any pins or pegs 13G in the wheel 134;

During the whole of the spraying operi.- tions tht` altitude of the mouthpiece 114EL of the nozzle 113 is being adjusted to lengthen or shorten the throw of the water according to the outline of the'area by the arm 114 rising to pass over projections on and being lowered by entering depressions in the plate 11G, said depressions being provided at points corresponding with portions projecting from hollows in the outline of the arear boundaries are to be watered, a jointed nozzle need not be used, as an ordinary rigid nozzle will serve as well.
