ABSTRACT:
A rotary drive sprinkler comprising a housing for coupling to an irrigation water supply, a sprinkler spray head rotatably mounted with respect to the housing and flow coupled to supply and a rotary drive mechanism located within the housing so as to be driven by the water supply and a transmission mechanism coupled to the drive mechanism and having first and second, oppositely directed, rotary outputs, there being further provided a reversing mechanism including a stop assembly having stop members arcuately displaceable with respect to each other between a juxtaposed position and a variable spaced apart position, a trip assembly responsively juxtaposed with respect to the stop members so as to be reversibly displaced by successive contacting with the stop members only when the latter are in their angularly spaced apart position, one of the assemblies being rotationally driven by the drive mechanism and a selective coupling responsively coupled to the trip assembly for coupling to one or other of outputs respectively in response to the reversible displacement of trip assembly and a drive member coupled, on the one hand, to spray head and, on the other hand, to the coupling so as to be rotationally driven about a drive axis.
