Abstract:
A rain water downspout for collecting water from an eaves trough mounted to a building and shooting the water away from the building, comprising:(a) a vertical downspout column for receiving and holding rainwater, the downspout column having an inlet at its upper end for receiving rain water flowing from the eaves trough and an outlet at its lower end for releasing rainwater, the outlet having an outlet opening that is smaller in size than the inside diameter of the downspout column, (b) a buoyant column inside the downspout column having a lower end that can block the outlet opening of the downspout column, the buoyant column capable of floating in the downspout column when water in the downspout column reaches a level, (c) a nozzle connected to the downspout outlet, the nozzle having an inlet and a discharge opening, (d) a resilient element disposed toward the top of the downspout column, the resilient element for receiving and absorbing the energy of the buoyant column when it ascends to the top of the downspout column and for applying a force to the top of the buoyant column to force it back down into the downspout column to increase the pressure of the water entering the nozzle inlet for a short period of time, (e) the downspout column adapted to fill with water to a sufficient level to cause the buoyant column to rise to permit a flow of water to pass through the downspout column outlet and into the nozzle to be discharged through the discharge opening of the nozzle and shoot away from the building until the buoyant column descends and blocks the downspout column outlet.
