Claims16
A sprinkler, comprising:
- a sprinkler body;
- a nozzle base disposed at a top of said sprinkler body;
- a gear drive assembly driving rotation of said nozzle base relative to said sprinkler body;
- a trip assembly connected to said gear drive assembly and having a trip arm switch selectively reversing a direction that said gear drive assembly rotates said nozzle base;
- a bull gear having a first trip dog member extending away from said bull gear and rotationally aligned to contact said trip arm switch;
- a first clutch member connected to said nozzle base and releasably engaged with said bull gear;
- and,
- an adjustable stop member having a second trip dog member that is rotationally aligned to contact said trip arm switch;
- said adjustable stop member being releasably engaged with said nozzle base via a second clutch member.
