1. A unitized sprinkler assembly comprisinga first housing assembly having an inlet end constructed and arranged to be connected with a source of water under pressure and a spaced outlet end,a second housing assembly having an inlet end and a spaced outlet end,the inlet end of said second housing assembly being constructed and arranged to mate with the outlet end of said first housing assembly and being connected in water pressure communicating relation therewith,a manually adjustable control mechanism carried by said first housing assembly between the inlet end and outlet end thereof constructed and arranged to control the flow of water under pressure from the inlet end thereof to the outlet end thereof in accordance with the manual adjustment of said manually adjustable control mechanism,a sprinkler head assembly having an inlet end disposed to receive water under pressure flowing from the outlet end of said second housing assembly,a base assembly constructed and arranged to support all of said assemblies on a ground area to be sprinkled and having said assemblies disposed in supported relation thereon,a structural connection between said sprinkler head assembly and said second housing assembly constructed and arranged to enable said sprinkler head assembly to oscillate about an oscillatory axis with respect to said second housing assembly,an oscillating mechanism mounted in said second housing assembly constructed and arranged to be operated by the flow of water under pressure between the inlet end and outlet end of said second housing assembly and connected with said sprinkler head assembly to oscillate said sprinkler head assembly about said oscillatory axis through repeated oscillating head cycles,said sprinkler head assembly being constructed and arranged to discharge water under pressure flowing through the inlet end thereof in a predetermined stream configuration so as to be distributed on the ground to be sprinkled in a predetermined water pattern determined by the oscillating head cycle thereof,each of said oscillating head cycles including a head stroke in one direction and a return head stroke in the opposite direction so that a corresponding dimension of said water pattern corresponds with the distance of the head stroke of each oscillating head cycle, andan adjusting mechanism constructed and arranged to enable the distance of the head stroke of each oscillating head cycle to be adjusted within a range between a minimum head stroke distance and a maximum head stroke distance so as to vary the corresponding dimension of said water pattern within a range between a minimum dimension and a maximum dimension.
