ABSTRACT:
A sprinkler (2) includes a rotary nozzle (6) mounted on a body (4). A reversible drive (12) includes an internal gear (14) connected to the nozzle (6), a motor (16) having a unidirectional output shaft (18), and an oscillating gear train (20) having two final drive gears (27) or (29) which rotate reversely relative to one another and are engageable with driven gear (14) for reversing the direction of nozzle rotation. The first and second final drive gears (27) and (29) are mounted on first and second pivot arms (22a) and (22b) and are part of two gear sets (26) or (28). The numbers of gears in each gear set (26) or (28) is selected in conjunction with the direction of the pivoting motion of the pivoting arms (22a) or (22b) so that the additional rotation induced on the final drive gears as they rotate above the stationary part of the gear train (20) will always be counter to the normal direction of rotation thereof.
