  • Lawn sprinkler with cam-controlled variable spray pattern
    Patent number: 5350115
    Abstract: An oscillating sprinkler adjustable to selectively alter and adjust the spray pattern as desired is provided. Adjustment is provided by an internal selectable cam connected to an external rotary dial at the distal end of the sprinkler. Placing the spray adjustment dial at the distal (non-hose) end of the sprinkler minimizes the chances of the operator getting wet while selecting the desired spray pattern while the sprinkler is in operation.
