Abstract
A lawn sprinkler is disclosed of the kind in which a tubular perforated rocking member dispenses irrigation water, the improvement consisting in that the mechanisms which impart to the tubular perforated member the rocking motion are enclosed in a sealed box the lid of which is conveniently removable, the gears and other component parts of the rocking mechanism being so arranged as to be capable of being individually removed and reassembled, each component part being univocally positioned. Thus maintenance, cleaning and replacement of the component parts of the rocking mechanism becomes both an easy and convenient operation.
