Description
6~
This i~vention relates to a novel intake nozzle and valve structure ~or the control of the spray pattern of water sprinkler heads, to a novel water deflection head, and to novel pop-up water sprinkler~ including s~ch novel intake nozzle and valve structure and novel water deflection head.
Underground sprinkler systems for lawns and gardens are well known i~stallations. These system~, when connected to a source of pressured water, permit spraying of a determined area.
Conventional sprinkling systems require many different spray patterns. State of the art sprinklers today have been designed to provide a full circle spray pattern, three-quarter circle spray pattern, one-half circle spray pattern or a one-quarter circle spray pattern, aach such spray pattern specifically spraying a particular segment of a full circle. These state of the art sprinklars are not adjustable and moreover, they are always a function of a circle, even if the entire periph~ry i5 not usually curved.
Patents have i~sued which proposed to provida improvements in lawn sprinkling heads, E~amples of such patents are: Canadian Patent No. 773,969 patented December 19, 1967 by G.J. Dyck;
Canadian Patent 873,764, patented June 22, 1971 by G.J. Dyck;

In spite of these patents, there is still a need for a sprinkler which would provide a one-quarter spray pattern or a three-quarter spray pattern. There i5 also a need for a single spray head which can be adjusted to provide a one-quarter square spray pattern, one-half square spray pattern, a three-quarter square spray pattern or full square spray pattern, in which the area of such spray patterns could be varied at will.

An object of another aspect of this invention is to provide both an improved intake nozzle and valve structure and an improved water deflection member having the means to adjust the size of the various selected one-quarter square spray pattern, one-half square spray pattern, three-quarter square spray pattern or full square spray pattern by a simple adjust~ent.
An object of yet another ~spect of this invention is to provide both an improved intake nozzle and valve structure and an improved water defle~tion member providing laminar flow to all ~761~s5 ~uadrants to result in equally square and controlled spray pa-tterns.

The peripheral surface o~ the rim 38 surrounding the well 3g is provided with a plurality of indexing members to indicate what ~276~3S5 spray pattern has been selected Within countersunk depression 40 is disposed a selection disc 41 whose lower stem 42 is provided with a central square aperture 43 to mate with the square end 4~ of upstandin~ central shaft 76. The selection disc 44 also includes a depending indexing pin 45 to cooperate with indexing projections 40a, 40b, 40c and 40d to aid in the proper selection of the spra~ patterns. ~he selection disc and the water deflection head 30 are maintained in assembled condition by means of screw 46 threaded into the tapped square upper end 44 of the upstandin~ central shaft 76.
In one embodiment of the invention, the frusto-conical plug 61 may be 0.700" in maximum diameter and may be provided with three upper ports 71a, 71b and 71c which may be 0.090" X 0.129"
in size and which are spaced 90 apart at the same axial length level of the frusto-conical termination 70. This configuration thus provides three ports 71a, 71b and 71c in a 180 conical face of the frusto-conical termination 70 and a 180 conical face free of ports. It is also provided with one lower port 72 which may be 0.125" X 0.09~" in size, spaced 90 from the last upper port 71a, 71b or 71c or 180 from the central upper port 71d, and thus is disposed in the centre of the 180 region of the frusto-conical termination 70 which does not have any upper ports. Each of the ports 71a, 71b, 71c and 72 communicates with its associated one of the four channels 69a, 69b, 69c and 69d.
g~
The frusto-conical hollow sleeve 74 includes four upper ports 77a, 77b, 77c and 77d which are identical in orientation to the upper ports 71a, 71b and 71c of the frusto-conical termination 70 but which may be either identical in size or larger provided the leading edge of the sleeve port can index the leading edge of an associated valve plug port. The frusto-conical hollow sleeve 74 may include one or two lower ports 78a, 78b which are 1a0 spaced-apart, which may be identical in orientation to the lower port 72 of the frusto-conical temination 70.
Figure 4 shows the interior structure of the hollow frusto-conical termination 70, which shows four separate and distinct and non-interconnected, longitudinally-extending peripheral channels 69a, 69b~ 69c, and 69d divided by respective walls 68a, 68b, 68c and 68d to provide up to four separate and distinct potential flow paths for the water. As described before, each of the channels 69a, 69b, 69c and 69d communicate with an associated one of the ports 71a, 71b, 71c and 72 of the frusto-conical termination 70. In addition, this Figure shows the hollow upstanding central bore 67 and the central hollow shaft 76.
Figure 5 shows the cross-section of the interrelationship of th~ hollow cloverleaf insert 82 and the stem 31 of the water deflection member 11. It is seen that, when the stem 31 of the water deflection member 11 is mated with the hollow cloverleaf ~t76~5s insert 82 by having its ri~s 33a, 33b, 33c and 33d Eit into slots 87a, 87b, 87c and 87d, there are four separate and distinct flow channels formed which are extensions of the aforementioned flow channels 69a, 69b, 69c and 69d.
Figure 6 shows another embodiment of the intake nozzle and valve structure of one aspect of the invention. In this embodiment, the frusto-conical ter~ination 70 and the frusto-conical sleeve 74 are replaced by functionally-equivalent structure. Thus, the lower section 62 terminates in a disc 670 lO which is provided with four flow through ports 671a, 671b, 671c and 671d. The frusto-conical sleeve is replaced by a flat indexing disc 674 provided with four equally spaced ports 677a, 677b, 677c and 677d which index precisely with the four ports ~71a, 671b, 671c and 671d. The purpose of the disc 674 is to adjust the flow of water from full flow to essentially zero flow, thereby adjusting the size only of any one of the previously selected one-quarter, one-half, three-quarter or ~ull square spray patterns. The selection of the spray pattern is made by using an apertured washer 79 having one, two, three or four apertures, to provide one-quarter, one-half, three-quarters or full square spray patterns, respectively.
To control the shape of the spray pattern in the embodiment shown in Figures 2-5, i.e. ~ull square spray pattern, three-quarter square spray pattern, half square spray pattern or one-quarter square spray pattern, the Erusto-conical hollow sleeve 74 ~695~i is rotated by means of the selection disc ~1 so that selected upper ports 77a, 77b, 77c and 77d of the frusto-conical hollow sleeve 74 register with selected ports 71a, 71b, 71c and 72 of the frusto-conical termination 70 as shown in Figs. 7~-7D. As seen in Fig. 7A, a full turn indexes, either partially or completely, ports 77a, 77b, 77c and 78a or 78b with ports 71a, 71b, 71c and 72, to provide a full square spray pattern. As seen in Fig. 7B, a one-eighth turn indexes, either partially or completely, port 77b with port 71b, to provide a one-quarter square spray pattern. As seen in Fig. 7C, a one-quarter turn indexes, either partially or completely, ports 77b and 77a with ports 71a and 71b, to provide a one-half square spray pattern.
As seen in ~ig. 7D, a one-half turn indexes, either partially or completely, ports 77a, 78a or 78c and 77c with ports 71a, 7~ and 71c, to provide a three-quarter square spray pattern.
To control the si~e of the area of the spray patterns, whether they be a full square spray pattern, one-quarter square spray pattern, one-half square spray pattern or a three-quarter square spray pattern, the indexing of the ports in the frusto-conical sleeve 58 to the ports in the frusto-conical plug 61 is increased. Thus, the more completely the ports are indexed, i.e.
the more the port is opened, the greater volume of water can flow through the ports, and so the greater the size or area of the spray pattern.
This i~vention relates to a novel intake nozzle and valve structure ~or the control of the spray pattern of water sprinkler heads, to a novel water deflection head, and to novel pop-up water sprinkler~ including s~ch novel intake nozzle and valve structure and novel water deflection head.
Underground sprinkler systems for lawns and gardens are well known i~stallations. These system~, when connected to a source of pressured water, permit spraying of a determined area.
Conventional sprinkling systems require many different spray patterns. State of the art sprinklers today have been designed to provide a full circle spray pattern, three-quarter circle spray pattern, one-half circle spray pattern or a one-quarter circle spray pattern, aach such spray pattern specifically spraying a particular segment of a full circle. These state of the art sprinklars are not adjustable and moreover, they are always a function of a circle, even if the entire periph~ry i5 not usually curved.
Patents have i~sued which proposed to provida improvements in lawn sprinkling heads, E~amples of such patents are: Canadian Patent No. 773,969 patented December 19, 1967 by G.J. Dyck;

These patents disclose sprinklers which provide either a one-half ~7~
square spray pattern or a full square spray pattern, by the ~s~

In spite of these patents, there is still a need for a sprinkler which would provide a one-quarter spray pattern or a three-quarter spray pattern.

The water sprinkler of aspects of this invention includes an apertured laminar flow sealing washer disposed between the hollow 25cloverleaf insert and the shaft of the deflection member, to pro-vide laminar flow control through four separate sections of the hollow cloverleaf insert.

Figure 1 shows the pop-up sprinkler head 10 of one embodiment of the present invention including a water deflection member 11 having a casing 12 operatively associated with, and vertically slidably disposable within, a conventional housing 13 ~27~i~5S
connected to a water supply pipe 14. Housing 13 is threadedly secured, in the conventional manner, by threaded coupling 22 onto threaded nipple 23 upstanding from water supply pipe 14. The "pop-up" sprinkler head 10 includes a threaded hold-down sleeve 15 to secure a hollow cloverleaf insert (not seen but which will be described later) to the intake nozzle and valve structure (not seen but also to be described;later). The intake nozzle and valve structure (not seen) is threadedly connected to the casing 12 by means to be described later. In addition, as is conventional in the art, the "pop-up" sprinkler head 10 includes an internall~ threaded cap 16 threadedly secured to the externally threaded end 17 of the housing 13. The casing 12 is freely slidably mounted within the housing 13, the upward movement of the casing 12 being limited by upper abutting surfaces of a flange 18 against a suitable seal 19, e.g. of rubber. A coil spring 20 helps to urge the casing 12 downwardly.
Such downward movement is limited by the water deflection member 11 being flush with the top of the threaded cap 16 and by the lower surface of the flange 18 resting on the upper surface of the interior base 21 of the housing 13.

~;~7~
The upper face of hollow, cloverleaf insert 82 includes a flange 85. Flange 85 is provided wi-th a central bore 86, through which upstanding central shaft 76 projects, frGm which extend 90 spaced-apart rectangular slots 87a, 87b, 87c and 87d.
Accommodated within upper chamber 61 by means of slots 87a, 87b, 87c and 87d is a water deflection member 11. Water deflection member 11 includes a lower stem 31 in the form of a central bore 32 from which radiates four 90 spaced-apart longitudinally-extending major ribs 33a, 33b, 33c and 33d to form four longitudinally-extending channel-forming quadrants 34a, 34b, 34c and 34d. Each quadrant 34a, ~4b, 34c and 34d terminates in its own partial cylindrical abutment 35a, 35b, 35c and 35d.
Likewise, each major rib 33a, 33b, 33c and 33d terminates in its own minor but wider, radial, longitudinally-extending partial wall 36a, 36b, 36c and 36d.
Stem 31 terminates in an integral water deflection head comprising a frusto-conical lower deflecting surface 37 and a rim 38.
The upper face of rim 38 is provided with a shallow well 39 and a concentric countersunk depression 40. The upper surface of well 39 along the periphery thereof is provided with a plurality of spaced-apart indexing projections 40a, 40b, 40c and 40d.

The selection disc 44 also includes a depending indexing pin 45 to cooperate with indexing projections 40a, 40b, 40c and 40d to aid in the proper selection of the spra~ patterns. ~he selection disc and the water deflection head 30 are maintained in assembled condition by means of screw 46 threaded into the tapped square upper end 44 of the upstandin~ central shaft 76.
In one embodiment of the invention, the frusto-conical plug 61 may be 0.700" in maximum diameter and may be provided with three upper ports 71a, 71b and 71c which may be 0.090" X 0.129"
in size and which are spaced 90 apart at the same axial length level of the frusto-conical termination 70. This configuration thus provides three ports 71a, 71b and 71c in a 180 conical face of the frusto-conical termination 70 and a 180 conical face free of ports. It is also provided with one lower port 72 which may be 0.125" X 0.09~" in size, spaced 90 from the last upper port 71a, 71b or 71c or 180 from the central upper port 71d, and thus is disposed in the centre of the 180 region of the frusto-conical termination 70 which does not have any upper ports. Each of the ports 71a, 71b, 71c and 72 communicates with its associated one of the four channels 69a, 69b, 69c and 69d.
g~
The frusto-conical hollow sleeve 74 includes four upper ports 77a, 77b, 77c and 77d which are identical in orientation to the upper ports 71a, 71b and 71c of the frusto-conical termination 70 but which may be either identical in size or larger provided the leading edge of the sleeve port can index the leading edge of an associated valve plug port. The frusto-conical hollow sleeve 74 may include one or two lower ports 78a, 78b which are 1a0 spaced-apart, which may be identical in orientation to the lower port 72 of the frusto-conical temination 70.
Figure 4 shows the interior structure of the hollow frusto-conical termination 70, which shows four separate and distinct and non-interconnected, longitudinally-extending peripheral channels 69a, 69b~ 69c, and 69d divided by respective walls 68a, 68b, 68c and 68d to provide up to four separate and distinct potential flow paths for the water. As described before, each of the channels 69a, 69b, 69c and 69d communicate with an associated one of the ports 71a, 71b, 71c and 72 of the frusto-conical termination 70. In addition, this Figure shows the hollow upstanding central bore 67 and the central hollow shaft 76.
Figure 5 shows the cross-section of the interrelationship of th~ hollow cloverleaf insert 82 and the stem 31 of the water deflection member 11. It is seen that, when the stem 31 of the water deflection member 11 is mated with the hollow cloverleaf ~t76~5s insert 82 by having its ri~s 33a, 33b, 33c and 33d Eit into slots 87a, 87b, 87c and 87d, there are four separate and distinct flow channels formed which are extensions of the aforementioned flow channels 69a, 69b, 69c and 69d.
Figure 6 shows another embodiment of the intake nozzle and valve structure of one aspect of the invention. In this embodiment, the frusto-conical ter~ination 70 and the frusto-conical sleeve 74 are replaced by functionally-equivalent structure. Thus, the lower section 62 terminates in a disc 670 lO which is provided with four flow through ports 671a, 671b, 671c and 671d. The frusto-conical sleeve is replaced by a flat indexing disc 674 provided with four equally spaced ports 677a, 677b, 677c and 677d which index precisely with the four ports ~71a, 671b, 671c and 671d. The purpose of the disc 674 is to adjust the flow of water from full flow to essentially zero flow, thereby adjusting the size only of any one of the previously selected one-quarter, one-half, three-quarter or ~ull square spray patterns. The selection of the spray pattern is made by using an apertured washer 79 having one, two, three or four apertures, to provide one-quarter, one-half, three-quarters or full square spray patterns, respectively.
To control the shape of the spray pattern in the embodiment shown in Figures 2-5, i.e. ~ull square spray pattern, three-quarter square spray pattern, half square spray pattern or one-quarter square spray pattern, the Erusto-conical hollow sleeve 74 ~695~i is rotated by means of the selection disc ~1 so that selected upper ports 77a, 77b, 77c and 77d of the frusto-conical hollow sleeve 74 register with selected ports 71a, 71b, 71c and 72 of the frusto-conical termination 70 as shown in Figs. 7~-7D. As seen in Fig. 7A, a full turn indexes, either partially or completely, ports 77a, 77b, 77c and 78a or 78b with ports 71a, 71b, 71c and 72, to provide a full square spray pattern. As seen in Fig. 7B, a one-eighth turn indexes, either partially or completely, port 77b with port 71b, to provide a one-quarter square spray pattern. As seen in Fig. 7C, a one-quarter turn indexes, either partially or completely, ports 77b and 77a with ports 71a and 71b, to provide a one-half square spray pattern.
As seen in ~ig. 7D, a one-half turn indexes, either partially or completely, ports 77a, 78a or 78c and 77c with ports 71a, 7~ and 71c, to provide a three-quarter square spray pattern.
To control the si~e of the area of the spray patterns, whether they be a full square spray pattern, one-quarter square spray pattern, one-half square spray pattern or a three-quarter square spray pattern, the indexing of the ports in the frusto-conical sleeve 58 to the ports in the frusto-conical plug 61 is increased. Thus, the more completely the ports are indexed, i.e.
the more the port is opened, the greater volume of water can flow through the ports, and so the greater the size or area of the spray pattern.
