A hose end pattern sprinkler has a sprinkler housing supported on a base with a hose end coupling for connecting a garden type hose to a water inlet of the housing, a pressure regulator having an inlet pressure balanced valve member which is adjustable externally of the housing for controlling the pressure of water flowing within the housing, a variable leaf spring stator for shaping water flow from the pressure regulator into a variable width stream in response to the water pressure, a water driven turbine including an impeller wheel having turbine vanes positioned to be impinged with water flowing past the variable leaf spring, a rotatable nozzle having an outer drive gear and triangular bottom nozzle inlets having apexes converging in a center bore, and an annular pattern plate of ring configuration having an internal gear, the plate being operable externally of the housing for moving the plate beneath the associated nozzle inlets with the pattern plate having a plurality of different configured pattern orifices for controlling water flow from the associated nozzle inlets to a selectable pattern, and a stream deflector normally biased toward a maximum stream deflecting position with a water pressure responsive piston provided for moving the deflector against its bias under the force on the deflector provided by water pressure within the nozzle.

A pattern sprinkler having a housing, a water inlet to said housing, nozzle means for spraying water from said housing and a water passage within said housing communicating between said inlet and said nozzle means, said sprinkler further comprising: an annular pattern plate means having a plurality of different configured spray pattern orifices provided threin in a circular array; means for mounting said annular pattern plate means in the path of water flow through said water passage between said inlet and said nozzle means to control the pattern of water spray from said nozzle means in response to the particular spray pattern orifice positioned in the path of said water flow; and water spray deflector means associated with said nozzle means for breaking up the nozzle water sprays emitted by said nozzle means, said deflector means including a plurality of deflection vanes biased toward a maximum spray deflecting position and water pressure operated means for urging said deflector vanes toward a minimum deflecting position in response to water pressure within said nozzle means.
