Field of the Invention The invention relates in general to sprinkler apparatus, particularly to apparatus especially suitable for use as a lawn sprinkler in which the pattern of the spray may be selectively varied.
2. Description of the Prior Art The prior art sprinkler apparatus may be divided into two broad classifications: (a) Those having a predetermined, unalterable pattern and (b) those in which the spray pattern may be altered.
Relative to those sprinklers having alterable spray patterns, it is advantageous to have a lawn sprinkler with a spray pattern that covers an area defined by a periphery that encompassed 360, or alternatively, one that may be used to spray any segment of 360. Such an apparatus enables sprinkling along a 180 line that may be defined by a curb without wasting water in the street. Also, such an apparatus enables the spraying of water over a 90 pattern, as between a driveway and a curb, or over a 270, as around the corner of the house, for example, or around any other angle between and 260.
Previously known apparatus for accomplishing such results have significant disadvantages. That apparatus sold under the trademark Rain Bird utilizes a number of parts that cause the spray nozzle to sweep the selected number of degrees and then return the sprinkler to the original setting. The complexity introduced by having a number of moving parts leads to occassional unreliability and maintenance expense.
Sprinklers of the type that may be used to water different patterns on a lawn are shown for example in US. Pat. Nos. 671,958; 2,790,680; and 3,985,38l, to mention but a few. Apparatus of these types, and all others with which I am familiar, cannot be utilized to sweep any pattern from 0 to 360 in the advantageous reliable and maintenance free manner of my invention.
SUMMARY OF THE INVENTION The invention may be summarized as sprinkler apparatus that includes a base to support a conduit extending upwardly from the base. A movable means is connected with the conduit for progressively covering or uncovering circumferential apertures to selectively vary the spray pattern. If none of the apertures are covered, the spray pattern encompasses 360. Progressive movement of the movable means covers first one and then others of the apertures such that the spray pattern encompasses segments of the original 360 area. Thus, the spray pattern may be varied from 360 to 0 in the preferred form of the invention. The preferred means for accomplishing the progressive covering or uncovering of the apertures includes a movable or a cap means carried by the conduit, with either the conduit or cap means having at least one row of circumferential aper tures and the other having an obliquely truncated portion adapted to cover first one and then progressively all the apertures to define the selected spray pattern. In perhaps its simplist form the conduit is an obliquely truncated right circular cylinder with threads on one portion thereof, and a cap means is threaded to fit over the conduit means and includes at least one row of circumferential apertures that are progressively covered or uncovered by the end. portion of the conduit as the cap is screwed or unscrewed.
BRIEF DESCRIPTION OF THE DRAWING FIG. 1 is a perspective view of the sprinkler apparatus embodying the principles of my invention, with the movable or cap means removed but positioned for assembly on the upright conduit;
FIG. 2 is a fragmentary longitudinal, sectional view of the sprinkler apparatus of FIG. 1, showing the cap means assembled on the conduit;
FIG. 3 is a fragmentary, longitudinal sectional view of an alternate form of the invention; and
FIG. 4 is a fragmentary, longitudinal sectional view of yet another alternate form of the invention.
FIG. 5 is a cross-sectional view as seen looking along the lines VV of FIG. 3.
DESCRIPTION OF A PREFERRED EMBODIMENT The numeral 11 in the drawing designates a base having a conduit means 13 that in this instance includes a body with an L-shaped portion 15 having a passageway threaded as indicated by the numeral 17 to receive one end of a garden hose or the like. The body further includes an upstanding portion 19, secured by suitable means such as the threads 21 to the L-shaped portion 15, and further includes another threaded portion23, preferably in a mid-region thereof. The upper end'25 of the threaded conduit is truncated in this instance to define an obliquely truncated right circular tubular cylinder, there being also a passageway 27 that communicates with the passageway in the L-shaped portion 15.
A movable cap means 29, threaded as indicated by the numeral 31 in FIG. 2, has an interior surface 33 adapted to closely fit over the exterior surface of the upstanding portion 19 of the body 15. Further, the threads 31 are adapted to mate with the threaded portion 23 of the upstanding portion 19. In addition, the cap means has a continuous circumferential row of apertures 35 which in this instance are formed in a horizontal plane perpendicular to the longitudinal axis of the cap 29 and also the upstanding conduit portion 19. Further, there may be an enlarged knurled protrusion 37 on the exterior of the cap means 29 for ease of gripping.
In operation, the threaded portion 17 of the L-shaped portion 15 is secured to a garden hose, and the cap means 29 rotated to engage its threads 31 with the threads 23 of the upstanding portion 19. Then the water supply is turned on to urge water into the body 13 and inside the cap 29. The close fit (preferably not over 0.001 inch) between the engaging interior surfaces of the cap 29 and the exterior surfaces of the upstanding portion 19 of the body prevents any substantial flow of fluid except through the apertures uncovered from the truncated upper end 25. Further, leakage past threads 23, 31 is minimized. Hence, substantially all the water is urged through the apertures in row 35. With the cap means shown in the position in FIG. 2 water is forced under pressure through all the apertures to define an essentially 360 spray pattern. Rotation of the cap clockwise as seen in FIG. 1 moves the row of apertures progressively over the truncated end 25 of the upstanding portion 19 of the body. Thus, initially one and progressively increasing numbers of apertures are covered such that the spray pattern decreases toward Alternate forms of the invention are shown in H68. 3 and 4. The cap 41 in F IG. 3 is threaded at 43 to engage the threads 45 of the upstanding conduit 47. A circumferential row ,of apertures 49 extend through the upstanding conduit 47, being adapted for progressive opening or closure by movement of an insert 51 having an obliquely truncated cylindrical end 53. The insert is moved downward through engagement of the opposite end 55 with the top of the cap, which engagement may be assured by the pressure of the fluid in the conduit 47 or by attachment of the end 55 with the top of the cap. FIG. shows in cross section a spline and splineway 56 that may be used in the FIG. 4 embodiment to prevent rotation of insert 51 such that the spray pattern does not accidentally rotate after placement of the sprinkler and establishment and location of a particular spray pattern.
In FIG. 4 the cap or movable means 57 has an obliquely truncated lower end portion 59 and threads (not shown) to engage the threads 61 of the conduit 63 and progressively cover or uncover the apertures of circumferential row 65. An O-ring 67 may be used to minimize fluid flow except through the apertures.
While I have shown the invention in only a few of its many possible forms, it should be apparent to those skilled in the art that it is not so limited but is susceptible to various changes andmodifications without departing from the spirit thereof.
