This invention relates to 4sprinklers ysuch as are arranged ,to be mounted in connection' With underground Water systems to lWateri 'large areas, such as park laWns,jgolf courses f f5 andthe like.v n
' kOne ofthe major objects ,invention is to providek a sprinkler-'of' the LopY posed-nozzle reaction-rotation,type,-,vvith a means so r-that the kWater passing through the ia sprinkler head and beforefreachi'ng the nozv 'zles, Will positively rotate the'head independ- 2f ently ofthe rotarymotion imparted therge i y, theseparate rota' i to 'by reason of saidffopposed nozzles.

A further object is to ay sprinkler.v y vor disappearing type (that 25 is one Which drops of itself'so-that it `isfliushV of the telescopic with the ground When'th'e Water is turned off) having this positive rotation structure arranged in connection therewithso that thea? be positively rotated as., v '30 soon as and only When-'it lifts to its proper operating position under thefinfluence of;the This Q feature n permits a greater range:A
