  • Fail safe lawn sprinkler device
    Patent number: 5372306
    Abstract: A sprinkler head assembly for a lawn sprinkler system includes a valve having a valve actuating member which is engaged by the sprinkler head when the sprinkler head is in place, holding the valve in an open condition, permitting water flow to the sprinkler head. When the sprinkler head is removed the valve is operated to a closed condition, cutting off water flow. The valve member has tabs that, upon operation to the closed condition, retain the valve member in that condition. The valve is made of material allowing the sprinkler head to break away from the valve without damage to either part.
