SPRINKLER Filed May 12, 1944 MORRIS D. MORGAN inventor attorney Patented May 30, 1950 PATENT OFFICE SPRINKLER Morris -D.Morgan, Spokane, Wash.

Application May 12 1944,. SerialNo. 535,275.

'4 Claims; ((31.299-67) This invention relatestoasprlnkler and, more particularly, to a rotaryspraying device useful in sprinkling lawns andjgardens.

It is my observation from a wide experience with sprinkling equipment, as now availablethat there are several disadvantages which detract from the use of such equipment. "I have noted that the majority of the spray producing devices make no "fully advantageous use of the power available tobreak up the Water into foglike particles. Another criticism of the present equipment lies in the improper distribution of the spray over an area being sprinkled, which is partly due to the necessity of so employing the available power'to effect highspeed rotation in such a manner that there is nolateral water throw of any consequence. Of the sprinklers available, intha't type which Idesignate as rotary reaction or'jetpropulsion' type, wherein the discharge ofwater'from anon-axial outlet results in the rotary movement of thespray head, the lateral and centrifugal components of force cross each other out, with the result that the spray head moves but the water, infairlylarge droplets, falls substantially at the point of ejection.

Havingin mind the defects of the prior art, it is an important'object or my invention to provide, in a sprinkler, improved spray formation to insure an evendeposit of fine spray over the areabeing sprayed.

Another'objeet of the invention'is the provision, in a sprinkler, or rotary meansother than reactionypropulsion to enhance fog formation.

A still further object of the invention lies in the improvement of fluid dispersionanddistribution over an area relatively larger than has heretofore'been possible by similar equipment.

These and other objects, as will be more apparent hereafter are accomplished by a mechanism which includes a base to rest on the ground. Acasing supported on the base, has a turbine chamber, in which is mounted a varied rotor against the vanes of which water introduced through a non-axial passage impinges to carry the rotor around. In this preferred'form of my invention the shaft of the rotor is tubularand has openings by which water may escape from the chamber and pass out along the axis of the rotor through-'aportion of the shaft whichextends externally of the chamber. Connected to the externalportion of the rotor shaft and laterally thereof is a cross head, which may include two or more. arms having spray nozzles, through which escaping fluid is discharged. Ground anchor means is provided upon the base for positively positioning the same during use. Hose couplin means is associated with the chamber inlet passage so that a Water hose or pipe may be connected with facility.

This preferred form of my invention as outlined above, together with certain modifications in detail, is illustrated in the accompanying drawings, in which:

Figure l'is alview in elevation army-sprinkler;

Figure 2 is an enlarged vertical sectional-view of the operating mechanism of my sprinkler. with portions omitted. for convenience of illustration;

Figure 3 is a lateral sectional view taken-on line 33 of Figure'l;

Figure 4 is a fragmentary vertical sectional view of the lower end of the rotorshaft;

Figure 5 is a bottom plan view of a vanesecuring collar used in my rotor;

Figure 6 is a fragmentary perspective viewyof a discharge nozzle; and

Figure 7 is an elevational view of a-modifield form of rotor that may be used in 'my sprinkler.

Referring to the drawings, the numeral I'll designates a supporting base for thecasing 'IZ which provides the interior chamber M. Onthe bottom of the base in boss it, I threadably mount the anchor pin it which may be insert-ed into the ground G to anchor securely in place the sprinkler during use.

An orifice 20 in the wall of the casing !2 permits the introduction of fluid thereto and the non-axial conduit 22 directs fluid to the cylinder in a chordal manner. A female coupling swivel cooperates with the male member 25 of a hose 28 whereby water is supplied to the sprinkler. In thelower portion of the chamber l4, axial thereof, I mount the adjustable bearing pin 38 having the threaded shank -32; whereby its shoulder portion 34 may be raised or lowered as desired.

The chamber I4 is closed by cover 36'which has a central bearing sleeve 33 aligned with the axis of pin 30.

The rotor-comprises thetube as, having lower openings 42 and a closed bottom it, provided with asuitable'opening to engage the pin 30. Between collars 46 and &8, which are secured by means of screws59, is mounted a plurality of blades 52, which stand substantially radial of the tube 46. As shown in detail in Figures' 2 and 5, the vanes 52 may have cars 54, which are engagedin recessesfit of the coliars 48 and 45 to lockthe same in place. The tubular shaft 40 extends'upwardly through the bearin sleeve 38. The upper collar 43 is closely adjacentto the lower end of the sleeve-38. The top of the collar" forms a shoulderfacing the sleeve. It is evident that the shoulder portion 34 of thepin 30 can be set'totheright elevation to maintain such spacing between the collar 43 and the sleeve 38' as to prevent any substantial endwise movement of the shaft 40.

Upon the upper end of the tube 48 I mount the T-shaped member 66, from the opposite sides of which extend the hollow distributor arms 62. As shown in Figures 1 and 6, each arm 62 has an outer portion 6 3 disposed at an angle thereto, on the ends of which are spray nozzles 66.

In Figure 7 the rotor tube 6'3, having the usual openings 45, is provided with vanes 53 that are i The rotor of Figure.

curved in a spiral manner. 7 may be interchanged with that of Figures 2 and 3, when it is desired to change the rotary characteristics of the turbine mechanism.

In operation, water under pressure is supplied by hose 28 to the passage 22 and is discharged into the chamber l4 through the orifice 20. The water thus enters the chamber in a non-axial direction to impinge upon the vanes 52 of the rotor and produces rotation of the tube 49. Ihe water escapes from the interior of the chamber l4 through openings 42 and passes out of the casing through the external portion of tube 49, from whence it is distributed by the arms 62 to the nozzles 66.

It will be seen that if the arms 62 and their angularly disposed portions 64 are directed radial of the axis of rotation, rotation produced by the turbine mechanism will create centrifugal force in addition to the outward radial flow of the discharging Water and that the water will be thrown a considerable distance from the sprinkler while also being broken up by the rotary action. In those cases where the angular portio 64 of the arm 62 is directed in reverse to the direction of rotation, as in a re-action wheel, there will nevertheless be additional centrifugal force produced by the rotor to effect outward throw of the water as it escapes at the ends of the arms through nozzles 66. It is possible by the use of my device to direct the nozzles into the direction of rotation, and, because of the tube, the upper collar being positioned adjacent to the bearing sleeve in the top of the casing, vanes extending between and secured by said collars in spaced relation about the tube, the fluid inlet being directed non-axially of the tube whereby to cause fluid entering the chamber to strike said vanes and effect rotation of the tube,

Jsaid tube havin inlet openings spaced axially ing including a chamber having a fluid inlet action of the turbine, to produce fog coupled with outward distribution over an area substantially larger than with a re-action wheel of similar size that depends for rotation upon only the escape of the water from the distributor arms.

While I have shown and described particular embodiments of my invention, it will occur to those skilled in the art that various changes and modifications may be made without departing from the invention, and I, therefore, aim in the appended claims to cover all such changes and modifications as fall within the true spirit and scope of my invention.
