ATTORN EY LAWN SPRINKLER Charles C. English, Shawnee, Okla.
Application December 3, 1956, Serial No. 625,855
4 Claims. (Cl. 29973) The present invention relates to lawn water sprinklers, and has reference more particularly to the portable type of sprinkler which is adapted to be attached to the end of a garden hose.
This application is a continuation in part of an application filed by me in the United States Patent Office on June 14, 1956, under Serial Number 591,399, for Lawn Sprinkler.
The prior art reveals a number of diiferent types of water sprinklers, but most of these devices have the common fault of dispersing the full force of the water pressure simultaneously through a plurality of nozzles or openings. This results in limiting the sprinkled area to a relatively small portion of the lawn, and necessitates the frequent movement of the sprinkler to a new location.
The principal object of the present invention is to provide a water sprinkler which will spray a substantially larger area than conventional sprinklers of a comparable size.
An equally important object is to provide a water sprinkler which is relatively small and light in weight, and thus may be easily moved from one location to another.
Another object is to provide a sprinkler of this class which features a water dispersing means for directing the full force of the water pressure against a plurality of angularly adjustable spray nozzles in consecutive sequence.
An additional object is to provide a sprinkler of this character which has only one continuously moving part to become Worn or get out of order.
A further object is to provide a sprinkler of this class which includes a plurality of restrictive spray nozzles carried by the top of the sprinkler, which may be manually adjusted for spraying a desired area.
The present invention anticipates a hollow cylindrical body having a lateral hose connection on a vertical axis and a pair of disks which are rigidly connected in spacedapart relation by a plurality of radially spaced vanes. The upper surface of the body is provided with a plurality of circumferentially spaced-apart spray nozzles. Each of the nozzles has a pivotally mounted discharge tip for selectively directing the water angularly upward or outwardly from the body. As water enters the body, rotating the disks by means of the vanes, a recess in the periphery of the uppermost disk emits water through openings in the top in communication with the spray nozzles as the recess uncovers and covers the openings in rotative sequence.
Other objects will be apparent from the following description when taken in conjunction with the accompanying single sheet of drawings, wherein:
Figure 1 is a top view of the sprinkler;
Figure 2 is a vertical cross sectional view taken substantially along line 2-2 of Fig. 1;
Figure 3 is a perspective view of the rotating disks and vanes, per se;
nited States Patent Figure 4 is an enlarged fragmentary vertical cross sectional view of the sprinkler top and one of the nozzles; and,
Figure 5 is a perspective view of one nozzle discharge tip, per se.
Like characters of reference designate like parts in those figures of the drawings in which they occur.
In the drawings:
The reference numeral 10 indicates the device, as a whole, which comprises, in general configuration, a substantially cylindrical hollow body 12 having a closed upper end or top 14 and a lower end closed by a bottom plate 16 removably connected to the body by screws 18. A tubular projection 17 is integrally carried by the Wall of the body in communication with its hollow interior for connection with a garden hose 21. The top 14 is provided with a plurality of openings or perforations 19 adjacent its periphery in circumferentially spaced-apart relation in communication with the interior of the body 12.
As shown in Figs. 1 and 4, the top 14 integrally carries a circular base 20 surrounding each of the respective openings 19. A discharge tip 22 is pivotally carried by each base 20 within a co-operating recess 24 formed in the base. The base members 20 may be formed separately from the top 14, as illustrated in Fig. 2, and joined theretoin any suitable manner, if desired. Each of the discharge tips 22 comprises a relatively small cylindrical section 26 having a cylindrical ejection end tip or spout 28 integrally joined to the periphery of the section 26. An axial bore or opening 30 is formed in the ejection tip 28 which extends diametrically through the cylindrical section 26. The wall of the opening 30 is arcuately curved outwardly as it approaches the periphery of the cylindrical section 26, on the side opposite the tip end 28, to form a flared end opening 32, as seen in Fig. 4 and as is shown by dotted lines in Fig. 5. Stub axles 34, carried by the cylindrical section 26, pivotally mount the discharge tip 22 within the base 20 on a horizontal axis perpendicular with relation to a diameter of the top 14. Thus, each of the discharge tips may be adjustably pivoted manually to any position between an outwardly directed position, with reference to the center of the body 12, as shown by solid lines Fig. 4, and an inwardly directed position as is illustrated by dotted lines. The flared end 32 of the tip opening 30 thus receives the full force of water pressure within the body 12 regardless of the positioning of the ejection tip 28.
A shaft or axle 36 is axially journaled by the top and bottom of the body and rigidly carries an upper disk 38 and a lower disk 40 in parallel spaced-apart relation adjacent the inner surface of the top 14 and bottom 16, respectively. The peripheries of the disks 38 and 40 are closely received by the wall of the body 12. The disks are rigidly interconnected by a plurality of vertically disposed radially extending vanes 42. The upper disk 38 is provided with a peripheral recess 44 formed between one set of the vanes 42 which permits water under pressure to enter the body and to be ejected outwardly between the said two vanes through the openings 19 and discharge tips or nozzles 22 in consecutive order as the disks 38 and 40 are rotated. The circumferential extent of the arc encompassed by the recess 44 is such that it substantially spans the distance between two of the openings 19 to prevent the disks and vanes stopping on dead center. Transversely the recess 44 is sufiiciently wide to uncover the lower end of each opening 19, as is clearly shown in Fig. 2. The vanes 42 extend inwardly from the circumference of the disks in angular relation with respect to the radius of the disks and end in spaced-apart relation from the axle or shaft 36 (Fig. l) to allow water entering the sprinkler to be directed between all vanes, and outward through the rerecess 44 and discharge nozzles 22, regardless of the position of the disks.
Obviously the lower disk 40 may be eliminated without altering the efiiciency or operability of the sprinkler.
Operation In operation the sprinkler is connected to a garden hose 21 and the sprinkler placed in the desired location. Water under pressure enters the sprinkler from the hose and revolves the disks by means of the vanes 42, thus spraying water outwardly through the nozzles 22 as the recess 44 is rotated. The screws 18 may be countersunk into the bottom in a conventional manner, if desired, thus permitting the sprinkler to be moved by dragging without entanglement with grass stems or roots.
Obviously the invention is susceptible to some change or alteration without defeating its practicability, and I therefore do not wish to be confined to the preferred embodiment shown in the drawings and described herein, further than I am limited by the scope of the appended claims.
