SPRINKLER HEAD Filed Feb. 1, 1955 I i /7 /5 30 l5 A-IZ l0 INVENTOR ARTHUR WIEBE ATTORNEY SPRINKLER HEAD Arthur Wiebe, Chico, Califi, assignor to Gustave Miller, Washington, D. C. I
Application February 1, 1955, Serial No. 485,401 I 4 Claims. (Cl. 299-60) This invention relates to a sprinkler system and head therefore and more particularly to a prefabricated plastic sprinkler head primarily adapted for use in underground sprinkling systems such as are installed for the irrigation of lawns, gardens, or the like.
A primary object of this invention is the provision of an improved sprinkler system including plastic heads which may be simply and expeditiously installed, at a compara: tively low cost, by reason of the elimination of tees, nipples, ells, couplings, etc.
An additional object of the invention is the provision of an improved, preferably integral, sprinkler head provided with means whereby the flow of water through the head may be readily and simply adjusted.
A further object of the invention is the provision of such a sprinkler head provided with anchoring means whereby the system, including the piping therefore, may be anchored at a predetermined underground level, with the top of the sprinkler head flush with the lawn or the like.
An additional object of the invention resides in the provision of a modified form of sprinkler head which may be readily applied to existing plastic hose or pipes.
Still other objects reside in the combinations of elements, arrangements of parts, and features of construction, all as will be more fully hereinafter pointed out, and disclosed in the accompanying drawing wherein there are disclosed preferred embodiments of this inventive concept.
In the drawing:
Figure l is a schematic side elevational view, partially broken away, showing a sprinkler system in accordance with the instant invention in installed position.
Figure 2 is an end elevational view of one of the sprinkler heads of Figure l, the feed pipe being shown in section.
Figure 3 is an enlarged sectional view of one of the sprinkler heads taken substantially along the line 3-3 of Figure 4 as viewed in the direction indicated by the arrows.
Figure 4 is a sectional View taken substantially along the line 4-4 of Figure 3 as viewed in the direction of the arrows, and
Figure 5 is an end elevational view of a modified form of construction, certain concealed parts thereof being indicated in dotted lines.
Similar reference characters refer to similar parts throughout the several views of the drawing.
Having reference now to the drawing in detail and more particularly to Figure 1 there is generally shown in fragmentary schematic side elevation a portion of a sprinkler system constructed in accordance with the instant invention, wherein 10 indicates a feed pipe, preferably of plastic, provided at spaced intervals with a plurality of integrally molded sprinkler heads 11 each consisting of a cylindrical shank portion 12 and an integral inverted frusto-conical portion 13, surmounted by a circular top 2,793,910 Patented May 28, 1957 ice larged circular chamber 17 which flares outwardly to an interiorly threaded bore 18.
The bore 18 has threaded thereinto a metallic plug member generally indicated at 20 which comprises an; upper plate 21 having a central aperture 22 and connectedby an externally threaded annular skirt on flange 23 to a lower plate 24. Lower plate 24 isprovided with a series of spaced circumferentially inclined passageways 25 communicating with chamber 17, in such manner that water under pressure entering chamber 17 passes through inclined apertures 25 in a rotary direction intothe chamber 26 between upper plate 21 and lower plate 24 and passes outwardly through aperture 22 with a swirling or rotary effect.
Depending from the center of lower plate 24 is a valve stem 30 terminating in a conical valve 31 adapted to be positioned a selected distance from valve seat 15a, which distance may be governed by rotation of the metallic plug 20, to control the volume of water passed from the pipe 10 through bore 15 into chamber 17.
Positioned on the lower side of each of heads 11 is an anchor bar 32 pivoted for rotation as on a pivot 33. In the original installation of the system, the anchor bars are adapted to be positioned longitudinally of pipe 10, in a previously dug trench or ditch, and turned transversely thereto, as best shown in Figure 2, prior to re filling the ditch, whereupon, when the ditch is filled, the cross piece 32 serves to anchor the pipe 10 and its associated sprinkler heads 11 securely in position.
. Figure 5 disclosed a modified form of construction particularly adapted for installation on an existing hose or plastic pipe 40. A suitable aperture 41 is cut in the pipe 40 at the point at which it is desired to install a sprinkler head 42 in all respects similar to the previously described head 11 with the exception of the fact that the stern portion is comprised of an upper portion 43 and a lower portion 44, each provided with appropriate coacting cutaway semi-cylindrical recesses 45 for the encirclement of the pipe 40.
The lower portion 44 is secured in fluid tight relation about the pipe 40 to the upper portion 43 about the pipe 40 by means of two stud screws 45, the heads of the screws 45 being suitably countersunk so as not to interfere with the pivoting of the stabilizer 46 on its pivot 47 to anchor head 42 in its trench of ditch. The valve mechanism of this form of head may be identical with that of the form of head shown at 11. In fact, the head 42 differs from that at 11 only by being transversely divided at the midline of the hose aperture therethrough, with the addition of studs, which may be self threading to hold more securely in plastic, to hold the separated portions together about the hose.
From the foregoing it will now be seen that there is herein provided an improved sprinkler system and plastic head therefore which accomplishes all the objects of this invention, and others, including many advantages of great practical utility and commercial importance.
As many embodiments may be made of this inventive concept, and as many modifications may be made in the embodiments hereinafter shown and described, it is to be understood that all matter herein is to be interpreted merely as illustrative, and not in a limiting sense.
Having thus set forth and disclosed the nature of this invention, what is claimed is:
1. An underground sprinkler system comprising a sprinkler head having a plastic body including an upper fluid discharging surface adapted to be positioned-flush with the ground surface, a vertical bore in said body and an underground pipe'co'mprising a fluid supply source in communication with said vertical bore insa'id head, said pipe extending transversely through said head, said pipe extending through a filled trench in the ground, and a head anchoring bar pivotally secured to the bottom thereof and rotated transversely of the trench previously to the filling of the trench.
2. The underground sprinkler system of claim 1, said plastic head having the plastic pipe thereof molded thereto.
3. The underground sprinklersystem of claim 1, said head being divided transversely at the midline of where said hose is secured transversely therethrough, and threaded means on opposite sides of said transversely extending hose securing said divided head portions about said hose.
4. A sprinkler system comprising a flexible nonmetallic conduit adapted to be buried in the earth, a plurality of elongated stand-pipes carried byand extending in the same direction from said flexible conduit and adapted to be buried in the earth together with said flexible conduit and with said stand-pipes disposed in a substantially vertical position, a spray head carried by the upper end of each stand-pipe and adapted to be located at the surface of the earth, said spray head including a spray opening for discharging Water upwardly, means providing a water tight connection between the lower end of each stand-pipe and said flexible conduit at intervals along said flexible conduit and means rigidly associated with said first mentioned means for resisting rotation of said conduit about its axis due to torque generated by a lateral force exerted against the upper end of said stand-pipe from a source above the ground, said last mentioned means having at least one portion extending laterally from said conduit.
