Abstract
An improved water sprinkler of the arm driven type which has a reverse drive arm movable into the water stream emerging from a replaceable nozzle, to provide rapid reverse rotation of the sprinkler. The improvement lies in a novel nozzle structure which limits movement of the reverse drive arm by an amount dependent upon the nozzle size, thereby resulting in substantially the same reversing force regardless of nozzle size.
