Abstract
A rotary sprinkler having an intermittent motion mechanism which includes a driving gear and a driven gear with the driving and driven gears being drivingly engageable. The driven gear has a first set of gear teeth on one level and a second set of gear teeth on a second level. The gear teeth of the first set are axially and circumferentially offset from the gear teeth of the second set. The driving gear has a single driving gear tooth drivingly engageable with the gear teeth of the first set to drive the driven gear and a circumferential surface axially offset from the driving gear tooth and cooperable with the gear teeth of the second set to substantially retain the driven gear against rotation when the driving gear tooth is not in driving engagement with the gear teeth of the first set.
