A water sprinkler of a new type has a spray arm which oscillates about a horizontal axis transverse or perpendicular to the length of the spray arm, in a see-saw fashion, to distribute water to a length of the lawn or garden area. Spray nozzles spaced apart on a distortable, peripheral wall along the length of the spray arm in a linear array are adjustable, by twisting the peripheral wall of the arm, to a circumferentially-arrayed, helical or spiral pattern, to distribute water to cover a selected width of the lawn or garden area. Both the angle of the oscillation and the twist of the wall may be selectively varied or adjusted to select respectively the length and the width of the area to be sprinkled. The twist is adjustably-fixed along and about the flow passage, as by an internal twist-setting arm. Also, the spray arm may oscillate about its center or one end thereof, depending on the oscillation mechanism used.

[ I claim:] [1.] A transverse axis water sprinkler for a lawn or garden area, the sprinkler comprising:a spray arm that is generally straight and extends along a longitudinal axis between ends thereof, the spray arm having a longitudinal water flow passage extending generally along said axis and enclosed by a peripheral wall and at least one end cap;a plurality of spray nozzles spaced apart along the peripheral wall of the spray arm generally from one said end to the other, each said nozzle communicating from the flow passage through the peripheral wall to an exterior thereof and in a direction generally perpendicular to the longitudinal axis of the spray arm;a connection for pressurized water to the water flow passage of the spray arm; anda movement mechanism which causes the spray arm to oscillate about a horizontal axis extending perpendicular to the longitudinal axis of the spray arm, reby pressurized water flowing through the water inlet will be distributed generally evenly upon a selected length and width of said lawn or garden area by oscillation of the spray nozzles on the spray arm about the horizontal axis.
