Abstract: A traveling sprinkler radio-controlled mechanism and warning device which obtains an adequate and controlled duration of watering at opposed ends of a field to be watered while concurrently insuring that over-watering will not occur whenever an unattended traveling sprinkler stops for any reason whatever. A re-settable time delay means is employed which obviates a common deficiency of under-watering at the opposed ends of the field while also preventing over-watering which heretofore occurred whenever an unscheduled stop occurred or where no shut down of the pump was provided for at the far end of the field. Radio transmitter and receiver means are used to transmit and receive a shutoff signal for a pump supplying water to the traveling sprinkler whenever the traveling sprinkler stops.

Abstract: A traveling irrigation sprinkler has a water-powered radial inflow turbine for driving a winch that pulls the sprinkler along a path of travel. Water is supplied to a sprinkler gun either directly from an inlet conduit, or indirectly by passing it through the turbine. A diverter valve proportions the direct and indirect flows and provides a first means of controlling the travel speed of the sprinkler. A shiftable transmission drivingly interconnects the turbine and the winch and provides a second means of controlling travel speed. The turbine includes a vaned runner and a scroll which circumferentially surrounds the runner to deliver water at a substantially uniform velocity to the periphery of the runner.
