Referring now to FIGS. 4 and 6, the resilient body 37 carried by the annular shoulder 36 of the end casing section 33 is integrally molded, as previously noted, whereby the same comprises the previously mentioned substantially cylindrical outer surface in which there are provided a plurality of pockets 37a arranged in circumferentially spaced-apart relation; and also, the resilient body 37 comprises the previously mentioned substantially annular inner surface in which there are provided a corresponding plurality of passages 37b arranged in circumferentially spaced-apart relation; and in the arrangement, the passages 37 b respectively communicate with inner portions of the pockets 37a. The ring 41 overlies the annular surface mentioned of the resilient body 37' and has a corresponding plurality of valve ports 41a formed therein and arranged in circumferentially spaced-apart relation; which valve ports 41a respectively communicate with the passages 37b formed in the resilient body 37; and which valve ports 41a commonly communicate with the composite cavity defined in the casing assembly. The band 39 overlies the cylindrical surface mentioned of the resilient body 34 and has a corresponding plurality of sets of sprinkler ports formed therein and arranged in circumferentially spaced-apart relation; which sets of sprinkler ports respectively communicate with the pockets 37a formed in the resilient body 37. The constructions of the elements 35, 3S and 46 respectively correspond to those of the elements 37, 39 and 41, as described above; whereby the resilient body 35 comprises the pockets 35a and the passages 3511, the band 38 comprises the plurality of sets of sprinkler ports, and the ring 49 comprises the valve ports 460.
More particularly, each of the sets of sprinkler ports formed in the band 39 comprises, as best shown in FIG. 2, three individual sprinkler ports 39a, 39b and 39c; and in the arrangement, the sprinkler ports 39a are arranged in a first annular array positioned around the band 39, the sprinkler ports 3% :are arranged in a second annular array positioned around the band 39, and the sprinkler ports 39c are arranged in a third annular array positioned around the band 39. The first annular array of sprinkler ports 39a formed in the band 39 are arranged in a first forwardly disposed lateral plane, indicated at 39A; the second annular array of sprinkler ports 3% formed in the band 39 are arranged in a second rearwardly disposed lateral plane, indicated at 39B; and the third annular array of sprinkler ports 39c formed in the band 39 are arranged in a third lateral plane, indicated at 39C and disposed intermediate the planes 39A and 393. The first sprinkler ports 3% are directed generally radially outwardly from the band 39 with a rearward inclination, as indicated by the correspondingly directed broken line 39a in FIG. 2; the second sprinkler ports 3% are directed generally radially outwardly from the band 39 with a forward inclination, as indicated by the correspondingly directed broken line 39b in FIG. 2; and the third sprinkler ports 390 are directed generally radially outwardly from the band 39 and substantially in the plane 39C, as indicated by the correspondingly directed broken line 390' in FIG. 2. Also, the individual sprinkler ports 39c are angula-rly offset with respect to the corresponding individual sprinkler ports 39a, and the individual sprinkler ports 3% are angularly offset with respect to the corresponding individual sprinkler ports 390, as clearly shown in FIG. 2.
In order to insure proper registry of the passages 37b formed in the resilient body 37 and the valve ports 41:: formed in the ring 41, the annular shoulder 36 carried by the end casing section 33 is provided with three angularly spaced-apart outwardly directed projections 36a that fit into three corresponding grooves formed in the inner surface of the resilient body 37 and that fit into three corresponding aligned grooves formed in the inner edge of the ring 41, as shown in FIGS. 4 and 6. The construction of the elements 34, 35, 38 and 40 respectively correspond to those of the elements 36, 37, 3? and 41, as described above; whereby the band 38, comprises the plurality of sets of sprinkler ports, each including the three individual sprinkler ports 33a, 38b and 380, with the three annular arrays of sprinkler ports mentioned respectively disposed in the three corresponding planes 38A, 38B and 38C, and respectively correspondingly directed, as indicated by the broken lines 38a, 38b and 38c, as shown in FIG. 2.
Further, the first device 10a comprises mechanism for selectively controlling valving of the valve ports 40a formed in the ring 46 and valving of the valve ports 41a formed in the ring 41, More particularly, a first annular trackway 61 is formed in the midportion of the tube 26 and surrounded by the intermediate casing section 3i; and a second annular trackway 62 is formed by the interior surface of the intermediate casing section 31; wherein the second annular trackway 62 surrounds the first annular trackway 61 in radially outwardly spaced apart relation therewith, as shown in FIGS. 4 and 8. A substantially U-shaped member 63 is arranged in the cavity 46 and including a pair of legs 64 and 65 and a connecting head 66. The ends of the legs 64 and 65 have longitudinally spaced-apart and aligned circular holes formed therein through which the intermediate portion of the tube 26 projects, the legs 63 :and 64 being disposed on opposite sides of the first trackway 61 formed in the tube 20. Accordingly, the member 63 is loosely mounted upon the tube 20 for relative rotation with respect thereto and constitutes a pendulum, as explained more fully below. A substantially circular hole 66a is formed in the central portion of the head 66, and an enlarged sphere or ball 67 is arranged mutually between the trackways 61 and 62 and within the hole 66a in the head 66. The hole 66a has a diameter that is slightly smaller than that of the sphere 67, so that the sphere 67 is thus trapped in the hole 66a in the head 66 of the member 63 and between the trackways 61 and 62. In the mechanism described, the member 63 is preferably formed of a suitable aluminum alloy, and the sphere 67 is preferably formed of a suitable brass or bronze.
In view of the foregoing, it will be understood that when the tube 26 is disposed in a generally horizontal position, the sphere 67 is gravity biased into a bottom position in the trackway 62, regardless of the portion of the casing assembly that is positioned downwardly, whereby the sphere 67 rolling in the trackways 61 and 62 into its bottom position pivots or rotates the member 63 as a pendulum into a downwardly directed position. The leg 64 of the member 63 carries a pair of outwardly projecting pins 68 disposed on opposite sides of the tube 2%; and a substantially disk-like valve element 69 is removably secured to the outer side of the leg 64 with a metal washer 70 disposed therebetween, the valve element 69 and the washer '76 both surrounding the adjacent section of the tube 25 The valve element 69 is properly located with respect to the adjacent leg 64 by the projection of the two pins 68 through two corresponding holes formed through the valve element 69. The valve element 69 is positioned immediately adjacent to the associated surface of the ring 40 and thus in cooperating relation with certain of the valve ports 49a formed therein. Similarly, the leg 65 carries a pair of outwardly projecting pins 71 disposed on opposite sides of the tube 20; and a substantially disk-like valve element 72 is removably secured to the outer side of the leg 65 with a metal washer 73 disposed therebetween, the valve element 72 and the washer 73 both surrounding the adjacent section of the tube 29. The valve element 72 is properly located with respect to the adjacent leg 65 by the projection of the two pins 71 through two corv 7 responding holes formed through the valve element 72. The valve element 72 is positioned immediately adjacent to the-associated surface of the ring 41 and thus in cooperating relation with certain of the valve ports 41a formed therein.
More particularly, as shown in FIG. 7, an upper lefthand segment has been cut-out of the valve element 72, whereby the valve element '72 overlies and closes all of the valve ports 41a provided in the ring 41, except those valve ports 41a that are disposed in the upper left-hand segment of the ring 41 and that are connected by the passages 37b to the ones of the sprinkler ports 3%, 3% and 3% formed in the band 39 that are directed upwandly and to the left, as viewed in FIG. 7; whereby the water fan that is projected from the band 39 is always directed upwardly and to the left, as indicated by the broken lines 39', as shown in FIG. 7, and as Viewed from the end casing section 33 toward the intermediate casing section 3-1, as seen in FIG. 2. Similarly, as shown in PEG. 8, an upper right-hand segment has been cut-out of the valve element 69, whereby the valve element 6? overlies and closes all of the valve ports 48a provided in the ring 40, except those valve ports ltia that are disposed in the upper right-hand segment of the ring 4t} and that are connected by the passages 35b to the ones of the sprinkler ports 38a, 38b and She formed in the band 38 that are directed upwardly and to the right, as viewed in FIG. 8; whereby the water fan that is projected from the band 38 is always directed upwardly and to the right, as indicated by the broken lines 33, as shown in FIG. 8, :and as viewed from-the end casing section 3-3 toward the intermediate casing section 31, as seen in FIG. 2. Since the rings 40 and 41 are respectively carried by the casing sections 32 and 33 they rotate therewith, as the casing assembly is rolled into various positions along the lawn 15, as shown in FIG. 1; however, the pendulum 63 is always downwardly directed, as previously explained; whereby the valve elements 69 and 72 always respectively uncover only the upper lefthand segment of the valve ports 41a and the upper righthand segment of the valve ports 490, with the constant result that the water fan 39' from the band 39 is directed upwardly and to the left and the water fan 38 from the band 38 is directed upwardly and to the right, as respectively illustrated in FIGS. 7 and 8, and regardless of the portion of the casing assembly that is positioned downwardly and in contact with the lawn 15, as shown in FIG. 1.
In the arrangement, the two valve elements 6% and 72 are of identical construction, and each thereof comprises a flexible sheet of resilient material, such, for example, as a synthetic rubber. Thus, to produce the two valve elements 69 and 72, two identical valve elements are merely assembled in oppositely facing directions upon the two sets of pins 68 and 71; which assembly produces the respective directions (left and right) of the two water fans 39' and 33' from the respective bands 39 and 38.
Finally, the first device that comprises a manually operable valve element 71 of substantially ring-like form and mounted upon the intermediate casing section 31 in surrounding relation therewith and selectively movable between an intermediate position, as shown in FIG. 4, a first end position, as shown in full lines in FIG. 5, and a second end position, as shown in broken lines in FIG. 5. The valve element 71 is of composite construction including an inner ring 72 formed of resilient elastomeric material, such as a synthetic rubber, and an outer ring 73 formed of :a suitable brass. The inner ring 72 selectively cooperates with the bands 38 and 39 selectively to close all of the sprinkler ports 33a, etc., and 3911, etc,
respectively formed therein; while outer ring 73 holds the inner ring 72 in place therein and serves as facility for efiectingready longitudinal shifting or sliding of the inner ring 72 upon the intermediate casing section 31 and upon the two bands 38 and 39.
When the valve element 71 occupies its intermediate position, :as shown in FIG. 4, the inner ring 72 is compressed between the outer surface of the intermediate casing section 31 and the inner surface of the outer ring the outer surface of the band 38 and some of the com pression is relieved upon the inner ring 72, with the 7 result that the inner ring 72 expands and fits substantially the sides of the concave band 38 serving to stopper all of the spninkler ports 38a, etc., formed therein; whereby the first device ma is operative to project only the water fan 3% from the band 39, as previously described in connection with FIG. 7. When the valve element 71 occupies its other end post-ion, as shown in dotted lines in FIG. 5, the inner ring 72 is positioned in surrounding relation with the outer surface of the band 39 and some of the compression is relieved upon the inner ring 72, with the result that the inner ring 72 expands and fits substantially the sides of the concave band 39 serving to stopper all of the sprinkler ports 39a, etc., formed therein, whereby the first device ltia is operative to pro-- ject only the water fan 38 from the band 38, as previously described in connection with FIG. 8.
Accordingly, the first device 10a is selectively operative to produce both of the water fans 38' and 39, only the water fan 38, or only the water fan 39', in response to operation of the valve element 71 into the individual ones of its three positions, as described above; which arrangement is very advantageous, since it accommodates adjustment of the characteristic of the first device 1% depending upon its individual location upon the lawn 15, so as' to prevent objectionable operation thereof to project its:
water fan upon a walkway, etc.
As a constructional example of the first device 10 w: the tube 2% may have an overall length of about 6 and an inside diameter of about 0.580"; the intermediate casing section 31 may have an overall length of about 7 and an outside diameter of about 2.340"; and the remainder of the dimensions of the other elements thereof may be selected from the scale of the drawings employing as a base the above noted dimensions.
Of course, the construction and arrangement and mode of operation of the other devices 10b and Ida are the same as those described with reference to the first device 10a;
and in passing, it is mentioned that there is no particular number of the devices that should be included in the garden hose, since such number is appropriately selected in view of the water pressure that is encountered in the water supply system to which the garden hose is connected. However, with the normal range of water pressure that is ordinarily encountered in city water supply ,systerns, the inclusion of about three of the devices in the garden hose is generally recommended. 7
In view of the foregoing, it is apparent thatthere has been provided a sprinkler attachment or device of improved and simplified construction and arrangement which is automatically operative to discharge water therefrom onlyin a generally upward direction, regardless of its supported position upon a lawn, or the like, and which may be selectively preset to limit the upward discharge of water therefrom, either to the right or to the left, as viewed from one end of the casing of the device, thereby always to effect gentle watering or sprinkling of the lawn, without damage thereto, and in a controlled or preset pattern covering a maximum area thereof.
