摘要： In a preferred embodiment of the present invention a sprinkler is provided, having a first shaft coupled to a drive mechanism and a grooved deflector. A second shaft is disposed within the first shaft, coupled to a water flow adjustment mechanism and an adjustment region on the top of the deflector. The first shaft transfers rotational movement from the drive mechanism to a grooved deflector on the top of the sprinkler. The second shaft rotates with the first shaft during normal operation due to a friction clutch within the sprinkler. When the user desires to adjust the water flow (i.e., the radius of the water), the friction of the clutch can be overcome by rotating the second shaft, increasing openings of flow passages within the sprinkler body. In this respect, flow adjustments can be made from the top of the sprinkler while the deflector rotates.

摘要： A rotary sprinkler having an adjustable arc segment whose angular extent and absolute direction relative to the ground are represented by an arc indicator, which arc indicator may comprise a band whose visible length represents the angular extent and whose position on the sprinkler points to the direction. The sprinkler may have the arc segment adjusted by a movable arc limit stop that is coupled to a toggle member only at drive reversal, and the sprinkler may be converted to full circle operation by raising the arc limit stop relative to a cooperating trip tab. A buckling spring assembly used to shift the drive comprises a compression spring held between two spaced pivot members, and the drive can be built in continuous and intermittent drive versions by replacing a few normal rotary gears with multilated gears. A friction clutch having asymmetric teeth for smooth operation prevents damage to the drive during forced nozzle rotation. A nozzle assembly includes a pivotal nozzle that carries a radius adjustment screw with the head of the screw received on top a flexible portion of a top cover, which top cover has laser etched indicia relating to various adjustments of the sprinkler. A flow shut off valve includes stream straightening vanes and a collar may be used to support the sprinkler on a stake or post for above ground installation.
