ABSTRACT:
A new and improved rotatable and oscillatable sprinkler apparatus is provided for use on a trolley pulled across a field to be sprayed with water. A rotation direction control assembly controls direction of rotation of a rotatable portion of a rotatable sprinkler head assembly. The rotation direction control assembly includes a revolving control element connected to the rotatable portion of the rotatable sprinkler head assembly. The rotation direction control assembly also includes a remotely controlled spray pattern selection assembly which controls a water spray pattern on the field by the remotely controlled spray pattern selection assembly contacting the revolving control element. The remotely controlled spray pattern selection assembly includes a first portion located adjacent to the stationary portion of the rotatable sprinkler head assembly. A second portion of the first remotely controlled spray pattern selection assembly is attached to the trolley. The first portion is responsive to the second portion and to a field-positioned actuator located at a selected position in the field. The field-positioned actuator actuates the second portion of the remotely controlled spray pattern selection assembly as the trolley is pulled across the field. The second portion actuates the first portion of the remotely controlled spray pattern selection assembly, and the first portion contacts the revolving control element of the rotatable sprinkler head assembly for controlling direction of rotation of the rotatable sprinkler head assembly, such that a water spray pattern is controlled on the field as the trolley is pulled across the field.
