A non-side-splash water sprinkler, including a sprinkler head rotatably mounted on a supply pipe, a nozzle from which the water issues in the form of a jet, and an oscillating arm drive member impinged by the water jet for rotating the head, is characterized in that it includes a splash guard carried by the sprinkler head at a location to substantially block sidesplash from the oscillating arm, and in that the rotational axis of the sprinkler head is substantially aligned with the general vicinity of impingement of the water splashed against the splash-guard such that little or no rotary torque is applied to the sprinkler head by the impingement of the water splashed against the splash-guard. A preferred embodiment of the invention is described in which a conventional sprinkler head is easily converted for non-side-splash operation by merely attaching the splash-guard and by providing a horizontal pipe for displacing the sprinkler rotational axis forwardly of the oscillating arm pivotal axis. |
