ABSTRACT:
A step-by-step rotary sprinkler head comprising a stationary annular housing assembly, an annular mounting member supported within the upper end portion of the stationary annular housing for rotational movement about a generally vertically extending axis generally coextensive with the annular axis of the housing assembly. The mounting member has three sets of equally annularly spaced holes extending vertically therethrough. An annular brake member has a set of equally annularly spaced stub shafts extending vertically upwardly therefrom which slidably engage within one set of holes. The annular brake member has a downwardly facing annular brake surface thereon which engages a fixed upwardly facing annular brake surface provided by the housing assembly. A sprinkler body assembly is carried by the mounting member and is fixedly secured thereto by bolts extending therethrough and threadedly engaged within another one of the sets of holes. A series of coil springs is mounted within a third one of the sets of holes to resiliently urge the interengaging brake surfaces together with a constant spring force.
