Abstract
A two-piece adjustable dial assembly between a link and a water discharge tube of a sprinkler for causing the rotational movement of the water driven shaft of the sprinkler to be transmitted through the link to the water discharge tube in any selected one of a plurality of different oscillatory cycles of movement. The two-piece adjustable dial assembly includes an arm member molded of plastic material having a mounting portion fixedly secured to the water discharge tube and a cylindrical portion having an axis disposed parallel to the oscillatory axis of said water discharge tube, and a dial member molded of plastic material extending through the cylindrical portion of the arm member and rotatable with respect thereto about the axis thereof. The dial member has a knob portion manually engageable to effect rotation of the dial member, a pivotal connection with the other end of the link and an elongated resilient cantilevered latching portion formed integrally with the dial member. The cylindrical portion has notched surfaces receiving the free end of the resilient latching portion for yieldingly retaining the dial member in any selected one of a plurality of positions of rotational movement corresponding to the selected oscillatory cycle of movement.
