Thereis a great number and variety of well known water sprinklers used to water, as for example, yards. The type ofiwatef sprinkler in which the invention provides an improvement might be classified more preciselyas the single stream impulse type sprinkler, the sprinklers withis'p ecial attachments to effect reversal of movement, or sprinklers such as is exemplified by US. Pat. No. 3,424,38l issued'lan. 28, I969 to c. L. Best.
BRIEF SUMMARY OF THE INVENTION The object of this invention is to improve the sprinkling of yards and/or other similar areas by the permanently installed systems'as well as by the portable sprinklingsystems. To this end, the invention provides in a rotary water sprinkler device driven by the impact of the water jet is suin g from a nozzle onja hammer, means to vary'the elevation, with respect to the horizontal axis, of the issuingfwater jet so as to vary the range of area sprinkled. This is accomplished by an adjustable nozzle inserted perpendicularly into the discharging end portion of'a watersupply pipe. The hammer is provided with extensions that will receive theimpact of the water issuing from the nozzle. The nozzle can be adjusted by means of a tool so as to emit a stream either parallel to the ground, 25 degrees from the horizontal axis or inbetween. This allows the use of more than one sprinkler at a time on one line, even if the areas to be watered are of different size. I
An advantage of this invention is to make possible the manufacture of sprinkler systems using about onefifth as much pipe.
Another advantage of this invention, is that it permits the issuing of very low water streams which resist breezes better than the streams issuing from conventional sprinklers. Further advantage is that water is saved since the stream of water can be better controlled according to the needs of the areas to be sprinkled.

DESCRIPTION OF PREFERRED EMBODIMENTS m ember ZO is journaled on main body 18 for rotation about a vertical axis. The swing member has hammer portions. The front hammer portion consists oftwo vertically extending members extending from A to AA, the purpose of which will be described hereinbelow. A spring 19 interconnects the swing member 20 and the main body portion 18. i
The main body portion 18 has a portion angled outwardly with'respect to the vertical axisas seen in FIG. 1. Body 18 ends at line B, at which point a protrusion 21 is provided. Protrusion 21 has an extension 14 ex tending beyond a nozzle 26. Extension 14 cooperates with the two vertical extensions of swing member 20 so as to provide a stop for swing member 20 and thereby cause the sprinkler to turn, this principle being well known in the art.
Inserted perpendicularly into the angled portion of body 18 is an adjustable nozzle 26. Nozzle 26 is provided with a teardrop shaped opening 24, which is parallel to and an extension of a conduit within the angled portion of main body 18, and with a slot on the side removed from body 18 (adjacent to teardrop opening 24) adapted for the application of a tool for adjusting the nozzle 26 to change the elevation of the stream of water issuing from nozzle 26. Thus, for example, in FIG. 4, the nozzle is shown as being positioned so as to produce a high stream of water, that is, at an angle with respect to the horizontal axis (Note that in FIGS. 4, 7, 11 and 12, the elements are shown at a level position but in operation they are elevated as in FIG. 1). FIG. 7 shows the nozzle as being set for a low stream of water, that is parallel to the ground.
FIG. 2 shows protrusion 14- without the nozzle 26. FIGS. 3-7, and 12 show protrusion 14 with nozzle 26 inserted therein. FIGS. 3, 5 and 6 show protrusion 21 with different openings 23, 22 which will provide different types of sprays, which is mostly a matter of choice. Similarly, FIGS. 8 and 9 show different nozzle openings 24, 25 that will produce different types of spray. FIG. 10 shows nozzle 26 with the screw driver slot and the teardrop opening.
In the embodiment shown in FIGS. [-10, the main body portion [8, the outwardly angled portion, and protrusion 21 are cast as a single unit.
FIGS. 11 and 12 show a threaded nozzle housing 27 with nozzle 26 therein. This embodiment is to be threaded directly into body 18 at line B in place of the standard fixed nozzles, when extension 21 is not provided.
In operation, if a stream of water is desired that is parallel to the ground, nozzle 26 is set as in FIG. 7. Water under pressure from a source (not shown) flows up through pipe stem 17, body portion 18, out through opening 24 or 25 of nozzle 26 and hits the extensions on swing member at around line A, swing member 20 moves and hits protrusion 14 which causes the sprinkler to rotate. If a stream of water is desired at an angle with respect to the ground, that is, at a higher elevation, nozzle 26 is set as in FIG. 4, and the water now issuing from opening 24, will hit swing member 20 at a point between A and AA depending on the new setting.
While this invention has been described with particular reference to the construction shown in drawings and while various changes may be made in the detail construction, it shall be understood that such changes shall be within the scope of the present invention as defined by the appended claims.
Having completely and fully described the invention, what I now claim as new and for which I desire Letters Patent is as follows:
1. In an impulse type sprinkler having a main body capable of rotation about a vertical axis,
an upstanding pipe stem with an enlarged head at its lower end, said pipe stem being threaded into the main body,
a standard pipe threaded member surrounding said pipe stem for fluidly connecting said main body to a source of water under pressure,
a washer between said enlarged head and the bottom part of said threaded member 4 a swingmember journaled on said main body for rotationabout saidyertical axis and having a hammer to receive the impact of water,
a spring interconnecting said swing member and the main body,
said body having a portion angled outwardly with respect to the vertical axis, an outlet on said portion, said swing member aligned with said outlet whereby water issuing from said outlet will impinge upon said swing member causing said swing member to move and hit some part of the main body wherein the improvement comprises an adjustable nozzle means inserted perpendicularly into said outlet for selectively varying with respect to the horizontal axis, the elevation of the stream of water issuing from said nozzle means, means on said hammer to receive the stream of water issuing from said nozzle means regardless of its elevation, and
wherein the outwardly angled portion has a protrusion extending past said outlet and is adapted to receive the impact of said swing member.
2. An impulse type sprinkler according to claim 1 wherein said protrusion, said adjustable nozzle form a separable member which is threaded into said outwardly angled portion.
3. An impulse type sprinkler as in claim 1 wherein said nozzle means is of a barrel type design having a teardrop type opening, said nozzle means having a slot on an enlarged side adjacent said teardrop type opening adapted for the application of a tool for adjusting the nozzle means to change the elevation of the stram of water issuing from said nozzle means, and wherein said means on said hammer to receive the impact of water includes two extensions extending in a substantially downward vertical direction.
4. An impulse type sprinkler according to claim 1 wherein said main body, said outwardly angled portion,
and said protrusion are cast as a single unit.
