Abstract
A pop-up rotary sprinkler with adjustable arc limits has an arc adjustment tool engaging member slideably mouted in a guide sleeve in the head of the sprinkler that has a progressively narrowing diameter. The member includes a radially expandable and contrastable collet at the upper end thereof and a pinion gear at a lower end thereof for engaging the teeth of a bull gear for setting at least one of the end limits of the desired arc. When the tool is inserted into the member, it moves downwardly, and a pair of flanges of the tool are locked into slots in the collet. The tool cannot be removed until it is pulled upwardly to permit the collet to expand radially to allow the flanges of the tool to be pulled past a ring at the upper end of the collet.
