In the conventional, typical oscillating, lawn or hose, sprinkler it is known to have a spray tube, having one row of uniform holes or nozzles, which oscillates back and forth in a "to and fro" motion. Water emitted through these holes or nozzles, form a spray of jets of uniform trajectory which form a single line where the jets fall on the ground. At the end of the stroke, where the "to and froth motion is halted temporarily, this gives rise to an undesirable concentration of water, known as "puddling." In this invention the positioning of the nozzles on the spray tube in a unique arrangement is used. This consists of using 1 row of nozzles of more than 1 size or type, or set at an angle of deviation from the vertical in the spray tube, or more than 1 row of nozzles with 1 or more nozzle sizes or types. With the use of this arrangement, varying trajectories are obtained, so the point of contact, where the jets hit the ground at the end of each stroke, is not in a single line, but is spread over a greater area. This distribution of the water, sprayed over a larger area, overcomes the unwanted so called, "puddling" effect. In the past, many attempts have been made to overcome this "puddling" effect. They have all been focused on mechanical designs to overcome the "top dead center" phenomenon, the pause at the end of the stroke, in the translation of rotary to reciprocating motion. These have given rise to numerous inventions, based on mechanical arrangements but my invention is the first, to my knowledge, to overcome the problem by changing the focus of attack from purely a mechanical one, to one of arrangement of the nozzles and hence the water spray pattern.
