ABSTRACT:
An oscillating sprinkler comprises a fixed base assembly (12) and an upper housing (14) from which water distributing arms (16, 18, 20, 22) extend. A bearing member (66) depends from the upper housing (14) and is seated within the base assembly (12). An upper surface (26) of the base housing (12) comprises an undulating cam surface and bend portions (110) of the arm members act as cam followers. Bend portions (110) engage cam surface (26) and cause a reciprocal tilting of the upper housing (14) about the bearing member (66) as the upper housing (14) rotates about the base assembly (12). Water ejected from orifices (114) in the arm members (16, 18, 20, 22) act to propel the upper housing along its rotational path. A cap member (144) is rotationally mounted to the top of the upper housing (14) and pressurized water ejected through orifices (148) in the cap member (144) act to rotate the cap member in a direction opposite to the direction in which the upper housing rotates.
