  • Impulse sprinkler deflector spoon
    Patent number: 4330087
    Abstract: A deflector spoon for a rotary impulse sprinkler includes upper and lower relatively sharply curved deflector faces separated by an intermediate, relatively gradually ramped deflector face. The three deflector faces are designed to react with a water stream from a sprinkler nozzle with the same driving force regardless of the specific water stream trajectory.

  • Self-compensating nozzle construction
    Patent number: 4161286
    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.
