8 Claims.

This invention relates to lawn sprinklers of the type particularly adapted for sprinkling large areas, such, for example, as lawns of wide expanse, golf courses, gardens and more particularly orchards and fields.

An object of the invention is to provide a sprinkler of the type carrying a wheel adapted to be rotated by the discharge of water-thereagainst and to itself break up and spray the water, and more particularly to provide means whereby the reversing action of the nozzleand associated parts may be accomplished in a substantially automatic manner so that an oscillatory action for the nozzle and associatedparts may be obtained;

The present invention together with its objects and advantages will be best understood from a study of the following description taken in connection' with the accompanying drawings wherein:

Figure 1 is a side elevational view of the improved sprinkler.

Figure 2 is atop plan view thereof.

Figure 3 is a detail sectional view taken substantially on the line 3-3'0f Figure 1.

Figure 4 is a-sectional ViEW'shOWiIlg the'mounting'for the rotary disk orwheel.

Figure 5 is a longitudinal sectional viewillustrating certain details hereinafter more fully referred to and with the gland nutremoved;

Figure 6 is a fragmentary detail sectional view at the top end of the nozzle.

Referring to the drawings by reference numerals, it will be seen that this sprinkler comprises a tubular member H formed at oneend as at I2 for threaded reception of a gland. nut or base casting |2a which latter also serves to couple the member with a suitable supply pipe.

Passing lengthwise through the tubular member H is a tube l3 one end of which extends into the end I?! of the tubular member H and is equipped with packing rings l4, retained by the nut |2a in a manner to provide in effect a packing gland for the exclusion of dust and dirt from the wearing part of the device.

The upper end of the tube |3 is externally threaded and screwed onto this end of the tube 3 as at I5 is one end of a nozzle IS.

The nozzle H5 at its free end is laterally enlarged as indicated generally at I! and at said end has threaded into the main bore l8 thereof a suitable tip It). In the enlarged end ll of the nozzle Hi there is also provided a by-passof relatively small diameter into the. outer end of which is threaded a smaller tip. 2| for a purpose hereinafter made manifest. Rearwardly of the passagelll. the nozzle internally is suitably providedwith a trash and dirt deflector lBa.

Adjacentthe head thereof thenozzle IS on its underside is provided with an apertured boss 22which receives one end of a shaft 23. The shaft 23 is held against axial movement through the opening in the bossl22 throughlthe medium of a collar 24 fixed. to, the shaft 23- at one side of the. boss and a nut 25 threaded on the end of theshaft at the side of the boss opposite to the collar 24 all of which is clearly shown in Figure l.

'Rotatably supported on the shaft 23'- laterally ofthenozzle IB'is aspray wheel or disk 26. The hub. of the wheel 26 is confined on the shaft between the collar 24 and a bushing assembly shown in Figure 4 which includes-a bushing cap 21 having an end fitting in a socket provided therefor in theladjacentxend: of the hub of the wheel 26, and a=second end provided with a tapered socket to receive the tapered end of a bushing member 28;eand against the free end of which bushing member 28 is threaded home a retaining nut 29 on the shaft 23. The hub of the wheel 26 may be also provided with an oil hole 3% for lubricating purposes as shown in Figure 4.

On the side thereof facing the nozzle |6- the wheel 26' is provided with a circular series of shortevanesaor fins 3| that extendsubstantially radial to the axis of the wheel, Also, integral with the wheel 26 at a suitable point in its periphery; is: provided aspoon 26a that, as shown is offset at an angle to-the plane of the wheel and is provided on one face thereof with vanes 3|a constituting continuations of certain of the vanes 3| as best shown in Figure-1. In connection with the above'it will also be noted that the lay-pass tip--2|-- is at the side of the head nearest to the wheel 26. Thus it will be seen that water issuing from thenozzle 2| and striking againstthe Vane equipped side of wheel 26 causes Wheel 26 to rotate and the water from nozzle l9 striking weight or spoon 26a will impart a brief but powerfulside' drive to the, sprinkler causing nozzle l6 and wheel'26to swing as a unit in a lateral clockwise direction.

For changinglthelateral direction of rotation of the nozzle I6 and wheel 26 as a unit so that the same will be caused to oscillate instead of rotating. in a continuous circle, there is carried on tubular member Figures 5 and 3, adjustable

cam clamping rings

33 and 35, the same being adjustable relative to each other andlsecuredlin adjusted position through the medium of these finger.

As shown in Figures 1 and 5 the cam 36 is d1sposed at a lower plane than the cam 33 so that a tripping finger 31 hereinafter more fully referred to, is adapted to ride on the out-side-edge of the cam 33 and on the inside edge of cam finger 36.

The tripping finger 31 together with arm 32 is formed integral with a hub, 39 fixed on one end of a stub shaft, 46 equipped on its free end with a nut 4| and journaled in a bearing boss 42 provided on the nozzle 5 in a manner as best shown in Figures 1 and 2.

A spoon or deflector 43 is adapted to move into and out of operative position relative to the tip l9 of the nozzle and is formed integral with a shank 44 that intermediate its ends is formed with a lateral shaft 45 journaled in a bearing boss 46 provided on the top side of the head I! of nozzle I6 as shown in Figure 2. At its free end the shaft 45 is provided with a nut 46 as shown, to retain the shaft against axial movement through the bearing boss 46. Also, the shank 44 adjacent the spoon 43 is provided with an angular projection 41 to which is connected one end of a spring 49 that is also connected to the free end of the arm 48 as shown in Figure 2. It will thus been seen that a swinging movement of the arm 32 will be transmitted to the spoon 43 and the spring 49, when the spoon is passed dead center, will serve to yieldably retain the spoon in the position to which it has been moved.

Rotative movement of the lever 44 and spoon 43 in one direction is limited by a stop lug 56 formed on one side of the nozzle I6 while rotative movement of the lever or shank 44 in a reverse direction is limited by reason of a down turned end 44a provided on the lever 44 to engage a stop lug 5| provided on the nozzle l6 as best shown in Figure 2.

From the above description it will be apparent that the sprinkler operates in the following manner. Water issuing from the small jet 2| of the nozzle impinges on the vanes or fins 3| of wheel 26 causing the wheel 26 to revolve or spin about the shaft 23 as an axis, the said Wheel rotating in a counterclockwise direction (see Figure 1). When the spoon 26a moves into the line of the large jet of water issuing from the nozzle tip I9, the jet striking the vane equipped face of the spoon 26a as said spoon 26a passes through the jet of water, causes a brief but powerful side drive to be imparted to the sprinkler, thus causing the nozzle l6 and wheel 26 to swing laterally as a unit in a clockwise direction.

As the nozzle l6 and wheel 26 swing in the direction just mentioned, arm 31 moves into engagement with the cam 36 so that about the time the nozzle l6 and wheel 26 has reached the limit of its movement in a clockwise direction, the arm 32 is tripped for swinging the spoon 43 from the full line position shown in Figure 1 to the dotted line position shown in said figure thereby placing the spoon in the line of the jet of water issuing from the nozzle I9. Obviously, when the spoon 43 is moved into the dotted line position shown, the jet of water impinging thereagainst will cause a powerful lateral side drive to the sprinkler resulting in a reversing movement of the nozzle [6 and wheel 26 as a unit. Thus the nozzle l6 and wheel 26 will be caused to swing laterally in a counterclockwise direction, a constant force being exerted by the water issuing from the nozzle l9 against the spoon 43.

As the nozzle l6 and associated parts now swing in this lateral counterclockwise direction, arm 3'! will move out of engagement with the cam 36 and into engagement with the cam 33. This will result in a tipping of the arm 32 and a consequent swinging movement of the spoon 43 back to the full line position shown in Figure 1, the spoon 43 being in this manner snapped out of line of the jet of water. Thus the parts are again in the position shown in Figure l to repeat the cycle of operation just described.

In connection with the above it will be noted that wheel 26 continuously rotates in one direction during the entire operation of the sprinkler and that the wheel 26 and the nozzle I6 as a unit swing laterally first in one direction and then in a reverse direction to insure a thorough sprinkling of a large area of lawn, orchard, field or the like.
