ABSTRACT:
An apparatus for the hydroautomatic sprinkling of land areas with hydrants which rise and lower which comprises a cylinder whose piston is displaceable by the water from one pipeline through either a long stroke or a short stroke depending upon the engagement of a guide with a selected groove in the piston to open a gate permitting water from this line to pass into a selected one of a group of hydrants, to drive the sprinkler upwardly and permit sprinkling. When pressure from another line is admitted to the opposite side of the cylinder the gate is closed.
