April 10, 1962 SPRINKLER HEAD FGR EMITTING SQUARE PATTERN SPRAY Filed March 30, 1960 fzgi 2/ /6 INVENTOR. 66 5 D27 5r A7 TOR/Vii tion and claims.
tlnited States Patent G 3,029,030 SPRINKLER HEAD FOR EMITTING SQUARE PATTERN SPRAY George E. Day, Sn, Lowell, Mich., assignor to G.D.M. Company, Lowell, Mich. Filed Mar. 30', 1960, Ser. No. 18,535 6 Claims. (Cl. 239--520) This invention relates to improvements in sprinkler head for emitting square pattern spray. The principal objects of this invention are:
First, to provide a sprinkler head attachable. to either a fixed or movable water distribution pipe for emitting a square pattern spray so that the sprinkler can effectively sprinkle lawns in rectangular areas defined by walks and drives without wetting the Walks and drives and so that a series of the sprinkler heads can uniformly cover all of a lawn area.
Second, to provide a square pattern sprinkler head which is relatively simple and inexpensive to manufacture and which is easily attached to a water supply pipe.
Third, to provide a square pattern sprinkler head which creates and emits two concentric spray patterns with one pattern covering a circular area and another pattern covering radially extending triangular areas at rectangularly spaced positions around the circular area to complete a rectangular pattern for the spray head as a whole.
Fourth, to provide a novel form of rectangular baffle or splash plate with a compound concavo-convex undersurface which will intersect and deflect a cylindrical stream of water intoa rectangular spray pattern.
Other objects and advantages of theinvention will be apparent from a consideration of the following descrip- The drawings, of which there is one sheet, illustrate a highly practical form of the sprinkler head.
FIG. 1 is a small plan view of the sprinkler head illustrating conventionally the square pattern of the spray emitted thereby.
FIG. 2 is a side elevational view of the central baflle plate and its supporting stem.
FIG. 3 is a side elevational view partially broken away in cross section of the bushing and intermediate deflector which receives and cooperates with the battle plate shown in FIG. 2.
FIG. 4 is a cross sectional view through the supporting ferrule or body which receives and supports the bushing and the bafile plate of FIGS. 2 and 3 and by means of which the sprinkler head as a Whole is attached to a supply pipe.
FIG. 5 is a plan view of the body shown in FIG. 4.
FIG. 6 is a fragmentary enlarged elevational view of the baffle plate shown in FIG. 2 as viewed from one corner of the rectangular baffle plate.
FIG. 7 is a fragmentary enlarged cross sectional view through the assembled spray head taken along the plane of the line 7-7 in FIG. 1.
The rectangular bafile plate 1 of the spray head as shown in FIGS. 1, 2 and 6 has four merging downwardly concave surfaces 2 which meet at the corners of the bafile plate. The central area of the underside of the baffle plate merges with a downwardly projecting and converging conical base 3 inclined at 45 from the axis of the base and merging at its lower end with a tapering stem 5. The lower end of the stem 5 carries a short cylindrical pin 6 which supports the stem, base and bafile plate as will be described presently.
The side surfaces of the conical base 3 are cut away along semi-cylindrical concave surfaces arranged perpendicularly to the diagonals of the square baffle plate 1. The intersection of these semi-cylindrical surfaces 3,629,030 Patented Apr. 10, 1962 ice with the conical surface of the base 3 appear as ellipses at 7 in FIG. 2 and as arcs at the sides of the FIG. 6.
The bushing 8 appearing in FIGS. 3 and 7 has a circular outline with a depending cylindrical neck 9 and an upwardly and outwardly inclined undersurface 10 on the flange ltla projecting radially outwardly from the neck 9. The surface 10 is inclined to the order of 10 from the horizontal. Interiorly the bushing 8 defines a central bore 11 which issized somewhat larger than the stem 5 of the baffle plateto freely receive the stem and define an annular flow passage 12 therearound as is shown in FIG. 7. An outwardly inclined and upwardly divergent conical surface 13 at the upper end of the central bore 11 is opposed to the inclined surface of the base 3 of .the battle plate to provide a narrow throat 14 with parallel sides inclined at 45 from the horizontal.
The bushing 8 is received in the ferrule or body 15 which is provided with a central cylindrical bore 16 sized to receive the cylindrical neck f the ferrule as a permanent press fit. Axially inwardly, or downwardly, from the bore 16 as viewed in FIGS. 4 and 7 the bore 15 defines a central passage 16A. The bore 16 constitutes an upwardly opening passage extending above the lower central passage 16A. A plurality of equal angular spaced vertical grooves 17 formed in the surface of the bore 16 afford uniform flow of water from within the body 15 around theneck 9 of the ferrule to the inclined surface 10. The upper end of the body 15 is cut away or beveled along the inner edge of the bore 16 as at 18 to permit water emerging through the slots 17 to spread substantially uniformly around the inclined surface 10 and be ejected'thereal'ong in a generally circular pattern as indicated by the dotted lines at 19 in FIGS. 1 and 7.
At its lower end the body or ferrule 15 is'provided with integral. spider arms 20 supporting a central boss 21 with a bore or recess 22 therein which receives and supports the pin 6 on the lower end of the stem of bafile plate 1. Engagement of the stem of the baflle plate with the boss 21 in the body determines the proper axial positioning of the baffle plate 1 with respect to the surrounding bushing 8. Water enters the body 15 through the openings between the spider arms 20 for delivery and diversion into separate streams alongside of the stem 5 of the baffle plate and through the several grooves 17 in the body to the annular inclined surface 10 on the bushing 8. The exterior of the ferrule of body 15 is threaded as at 23 for attachment to any suitable internal thread in a water supply pipe or conduit.
As appears most clearly from FIGS. 1 and 7 the stream of water delivered through the grooves 17 is deflected into the generally circular pattern 19 and discharged at a relatively flat angle as has already been described. The annular stream of water directed through the passage 12 between the stem of the bafile plate and the inner bore 11 of the bushing is first deflected and projected outwardly through the inclined throat 14 at a substantially higher angle of 45 as indicated by the dotted lines at 24 in FIGS. 1 and 7. Part of these projecting spray elements 24 deliver to a larger circular area than the inner area 19 by striking against the downwardly convex under surfaces 2 on .the battle plate. The rest of the spray or stream developed along the conical base 3 is deflected outwardly where it travels across the semi-cylindrical surfaces 7 underneath the corners of the baffle plate 1 thereby developing four rectangularly arranged streams or sprays indicated by the dotted lines 25 which project upwardly and therefore radially outwardly somewhat further than the other radially projecting spray lines to fill in and complete the rectangular overall spray pattern of the spray head. It will thus be seen that the three piece head structure is easily assembled and attached to a supply pipe to provide the rectangular spray pattern and the other objects set forth at the beginning of this description.
