Abstract
A rotary indexing nozzle head is provided wherein a dome like structure includes a rotating nozzle part supported by bearings interiorly thereof. The exit portion of the nozzle member includes a flexible bellows like structure which expands under the influence of water pressure and causes a lip thereon to engage an appropriately spaced wall for holding the nozzle in a specific location until the water pressure is relieved whereupon the bellows structure contracts and removes the engaging lip from the adjacent wall. A nozzle is caused to index by the jet of water impinging upon the curved surface of the lip 34 thereby causing the nozzle member to move sidewise, that is to say rotationally, until the lip is moved out far enough by the water pressure to cause the lip to engage the adjacent wall of the dome. The walls of the dome are spaced around its periphery so as in effect to provide openings for the jet of water to come through.
