Patent attributes
A sprinkler apparatus comprises a water wheel that is configured to be alternatively driven in a first wheel direction by a first fluid flow and a second wheel direction by a second fluid flow. The water wheel drives a water tube having at least one fluid outlet. The water tube is moveable in a first tube direction in response to the water wheel being driven in the first wheel direction, and is further moveable in a second tube direction in response to the water wheel being driven in the second wheel direction. The sprinkler apparatus further comprises a switch wheel positioned to receive an initial fluid flow and generate the first and second fluid flows therefrom. In particular, when the switch wheel is in a first position, the first fluid flow is generated. When the switch wheel is in a second position, the second fluid flow is generated.
