ABSTRACT:
Arc adjustment structure is provided for a rotary sprinkler having a rotatable nozzle supported from a shaft with the reversing mechanism attached to the nozzle and extending from the nozzle in the direction of the shaft. A notched ring is fixedly attached to the shaft below the nozzle. A first wire locking collar has one end compressively encircling the shaft above the annular gear and the opposite end formed in a loop extending radially from the shaft and terminating in a lateral end section for engagement with the teeth of the gear. A second wire locking collar has one end compressively encircling the shaft below the annular gear with the opposite end formed in a loop extending radially from the shaft and terminating in a lateral end section for engagement with the teeth of the gear. The locking collars are positioned such that the loops intercept the actuating arm of the reversing mechanism as the nozzle of the rotary sprinkler rotates on the shaft. The locking collars are positioned to any selected position about the circumference of the annular gear to control the arc through which the sprinkler operates.
