Abstract
An actuator assembly for a rotatable sprinkler head includes a base supported for rotation on a stationary platform assembly, the actuator assembly comprising a hub mounted for rotation on a shaft supported in the base; a lever arm pivotally mounted at one end to the hub and extending downwardly toward a stop plate assembly on the platform assembly, the lever arm having a free end extending toward the stop plate assembly; the stop plate assembly configured to define two or more arcuate paths of travel for the lever arm, the paths being radially offset relative to the hub; and wherein the lever arm is adjustable to locate the free end in any of the two or more arcuate paths of travel.
Claims22
An actuator assembly for a rotatable sprinkler head having a base supported for rotation on a stationary platform assembly, the actuator assembly comprising a hub mounted for rotation on a shaft supported in said base;
- a lever arm pivotally mounted at one end to said hub and extending downwardly toward a stop plate assembly on said platform assembly, said lever arm having a free end extending toward said stop plate assembly;
- said stop plate assembly configured to define two or more arcuate paths of travel for said lever arm, said paths being radially offset relative to said hub;
- and wherein said lever arm is adjustable to locate said free end in any of said two or more arcuate paths of travel.
An actuator assembly for a large volume sprinkler head mounted for rotation relative to a stop plate assembly, the actuator assembly comprising a lever arm on said sprinkler head adapted to cooperate with said stop plate assembly to define different paths of travel for said sprinkler head;
- said lever arm movable radially between said different paths of travel.
