Abstract

A sprinkler includes a tube rotatably secured in a base for receiving water. A pipe has an extension rotatably secured to the tube and has a number of annular recesses and ports. A number of sleeves are rotatably engaged in the annular recesses of the pipe and each has one or more outlets adjustable to different angular position relative to the pipe for allowing the pipe to be rotated by water flowing out through the outlets. A bar may secure the pipe to the tube for allowing the tube and the pipe to be rotated in concert with each other.

Claims

1. A sprinkler comprising:

a base including a tube for receiving water, said tube including a stud,

a pipe including an extension rotatably secured to said stud of said tube for receiving water from said tube and for allowing said pipe to be rotated about said stud, said pipe including a plurality of annular recesses and a plurality of ports communicating with said annular recesses, and

a plurality of sleeves rotatably engaged in said annular recesses of said pipe, said sleeves each including at least one first outlet communicating with said port for allowing water to flow out of said first outlet via said port,

said sleeves and said first outlets of said sleeves being adapted to be rotated relative to said pipe for allowing outlet water to force said pipe to rotate about said stud.

2. A sprinkler according to claim 1, wherein said sleeves each includes at least one second outlet, and a nozzle secured in said second outlet, said nozzle includes an inclined passage for allowing the outlet water to be inclined relative to said second outlet.

3. A sprinkler according to claim 2, wherein said second outlet each includes at least one rib for engaging with said nozzle and each includes a cap for securing said nozzle in said second outlet.

4. A sprinkler according to claim 1, wherein said pipe includes at least one nozzle engaged in said first outlet.

5. A sprinkler according to claim 1 further comprising a conduit including a first end having a ball rotatably engaged in said stud and including a second end, a gasket engaged between said ball and said stud, a cover secured to said stud for rotatably retaining said ball in said stud, said extension of said pipe being rotatably engaged in said second end of said conduit.

6. A sprinkler comprising:

a base,

a tube rotatably secured in said base for receiving water, said tube including a stud and including at least one projection,

a pipe including an extension rotatably secured to said stud of said tube for receiving water from said tube and for allowing said pipe to be rotated about said stud, said pipe including at least one pin, and

at least one bar including a first end engaged with said at least one projection of said tube and including a second end for engaging with said at least one pin and for securing said pipe to said tube and for allowing said tube and said pipe to be rotated in concert with each other about said tube.

7. A sprinkler according to claim 6, wherein said at least one bar includes a plurality of apertures for engaging with said at least one projection and for allowing said pipe to be adjusted to different inclined angle relative to said tube.

8. A sprinkler according to claim 6, wherein said second end of said at least one bar includes a hook for engaging with said at least one pin and for allowing said hook to be disengaged from said at least one pin.
