Abstract: The self cleaning rain gutter system of this invention has the quadruple advantage of being easy to install, being clog resistant, being self cleaning, and being without visible slope. Ease of installation is accomplished by modular sections made up of box, gutter and louver rack. These are simply installed level, using the fascia board as a guide as well as a support. A modular section may be installed fully assembled, with preset slope and leader funnel with cleaning water connections--or, at the option of the installer, may be mounted in a two step procedure, first the support box and then the gutter and louver rack. Clog resistance is provided by an integral top grating which interdicts most leaves and twigs as well as the occasional tennis ball. These larger items tend to provide the framework for clogs. The smooth rounded cross section of the bottom of the inner gutter also tends to resist clogging.

This substantially reduces part count for field use and system installation time. The joints of the riser provide leakproof movable connections which allow for the position adjustments of the riser and connected head.

A normally open spring loaded valve is positioned in a conduit to which the sprinkler head or the like is attached. A stem or rod is positioned in engagement between sprinkler head and valve so that upon displacement the stem may be broken off if of frangible material, or otherwise displaced and the valve is urged into closed position. Upon replacement of the sprinkler head or the like in proper position the rod is replaced to maintain the valve in open position.

Abstract: A sprinkler system for plants and schrubs growing on the side of a hill has non-drain valves connected at discharge heads that are positioned at elevations below the main control valve for the system. The non-drain valves are opened by pressure of water exerted when the main control valve is opened. After the main control valve is closed and water pressure in the pipe system that feeds the discharge heads falls to a selected value, the non-drain valves automatically close, thereby preventing drainage from the discharge heads of water retained in the pipe system between the relatively low discharge heads and the relatively high control valve.
