Abstract
A water sprinkler for irrigating lawn and garden areas has two axes of movement, one transverse to the other. A barrel moves or oscillates on one horizontal axis to direct water spray from nozzles carried on the barrel across the length of the area, and the nozzle outlets also simultaneously move or oscillate on axes transverse to the barrel axis to spray water across the width of the area. As the nozzle outlets move or oscillate in the two transverse directions, the ground area is irrigated uniformly over time by application of water in a criss-cross pattern. The area sprayed can be surprisingly large compared with single-axis oscillators, or the area may be limited to a single row or a narrow rectangular area, by adjustment of the barrel and outlet movement and/or the water pressure.
