Claims.

My invention relates to a sprinkling device, more particularly for use in connection with stationary water outlet conductors positioned in lawns, yards or the like and the objects of my invention are:

First, to provide a device of this class which may be so arranged that the pattern of spray may be varied to cover a rectangular or odd shaped plot of ground;

Second, to provide a sprinkling device of this class having a novel combination atomizing and spray directing wheel;

Third, to provide a sprinkling device of this class in which cam means is provided for use in controlling the spray and limiting the same to a rectangular or other odd shaped plot of ground or plot of ground varying in size which may be accomplished by simple adjustment of the cam member;

Fourth, to provide a sprinkling device of this class which issues fine misty droplets of water both suitable for the watering of plants, flowers and shrubbery to promote the proper growth of the same;

Fifth, to provide a sprinkling device of this class which is very positive and dependable in operation; and

Sixth, to provide a sprinkling device of this class which is very suitable and economical of construction, efficient in its action and which will not readily deteriorate or get out of order.

With these and other objects in view as will appear hereinafter my invention consists of certain novel features of construction, combination and arrangement of parts and portions as will be hereinafter described in detail and particularly set forth in the appended claims, reference being had to the accompanying drawings and to the characters of reference thereon forming a part of this application in which:

Figure 1 is a top or plan view of the sprinkling deviceand Fig. 2 is a side elevational view of the sprinkling device showing portions broken away and in section to facilitate the illustration.

Similar characteris of reference refer to similar parts and portions throughout the several views of the drawings:

The water outlet coupling l, stationary cam 2, traversing arm 3, nozzle member 4, distributor wheel 5 and the lever B- constitute the principal parts and portions of my sprinkling device.

The stationary water outlet coupling I may be connected with the conventional water vertical pipe or any other hollow tubular conductor. This stationary water coupling I is substantially conthe stationary coupling ventional in form and is maintained in stationary upright position substantially in the middle of the lawn, garden or plot of ground and the stationary cam 2 is connected in concentric rotatably vertically adjustable relation with the coupling I by means of the nut lb screw-threaded on the coupling I and engaging one side of said stationary cam 2, operating as a lock nut as shown best in Fig. 2 of the drawings.

The upper edge of this cam portion 2 is provided with elevated portions 2a and recess portions 212 about its peripheral edge. The stationary cam 2 is rigidly secured to the coupling member so that it cannot rotate member I, all as shown best in Fig. 2 of the drawings. The traversing arm 3 is a hollow tubular arm and is revolubly mounted over the stationary cam 2, all as shown best in Fig. 2 of the drawings. The sleeve 3a is screw threaded to the hub of the arm 3 and is revolubly mounted in the coupling l.

Positioned at the lower end of the sleeve 3a is a gasket 3b which forms a passing packing sleeve for water passing upwardly, as indicated by arrows in Fig. 2 of the drawings through the tubular sleeve 3a and into the traversing arm 3 toward the nozzle 4. Secured on the jet end of the traversing arm 3 is a bracket 5d and a nozzle is connected to the said end of the traversing arm 3.

Pivotally mounted on the downwardly extending portion of the bracket 511 is the shaft 5b journalled on the pin 50. Rotatably mounted on the shaft 5b is the distributor wheel 5 which is provided with notches 511 on its lower side which notches extend radially to the periphery of the the distributor wheel 5.

Rigidly connected to the shaft 5b is the lever B which engages the

cam portions

2a and 2b of the stationary cam 2. As shown in Fig. 1 of the drawings this lever 6 is curved and contacts the stationary cam 2 at a position which is parallel to the radial disposition of the traversing arm 3.-

stantially as follows: When this sprinkling device is positioned in substantially the middle of a plot of ground, garden or lawn, water enters l, passes upwardly through the sleeve 3a and into the traversing arm 3 toward the nozzle 4. The water jet issuing from the nozzle 4 impinges on the notch portion 5a at the periphery of the distributor wheel 5 atomizing the water and causing a fine spray to be issued radially from the axis of the sleeve 3a. It will be here noted that one side of each of the notches 5a of the distributor wheel 5 are at substantially right angles to the axis of the jet issued by the nozzle 4 which causes the distributor Wheel 5 to rotate about the shaft 51).

During the operation of the distributor wheel 5 and the nozzle 4 as water is issued therefrom, the torque created by impingement of water on the wheel 5 outwardly of the axis thereof causes the traversing arm 3 to rotate in the direction as indicated by arrows in Fig. 1" of the drawings. The lever B in connection with the shaft 5?) pivotally mounted on the pin in connection with the bracket 5d traverses the stationary cam I 2, engaging the elevated and recessed cam portions 2a and 23; causin intermittent tilted relationship of the shaft 5h together with the distributor wheel 5 which changes the elevation of the spray issued from the periphery of the distributor wheel 5.

The recessed cam portions 212 permit the downward gravitational travel of the lever 6 tilting the upper end of the shaft 3?) inwardly toward the axis of the traversing arm 3 elevating the angle of departure of the spray issued from the periphery of the distributing wheel but the recessed cam portions 21)- provide means for elevating the spray to an angle of departure which will carry said spray to the corners of a rectangular slot. Thus, the shape of the cam member 2 dictates a substantially square spray pattern. This cam 2 may be adjusted vertically by means of the nut lb for extending or decreasing the overall dimension of the rectangular pattern of spray issued from the distributor wheel 5. I

It will be noted that the cam 2 may be provided in other forms in order to control a spray pattern adaptable to various shaped plots of ground.

Though I have shown and described a particular construction, combination and arrangement of parts and portions I do not wish to be limited to the particular construction, combination and arrangement, but desire to include in the scope of my invention the construction, combination and arrangement substantially as set forth in the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
