Claim Text:
1. An automatic retractable gutter assembly for dispensing rainwater collected in a gutter, said assembly comprising: a down-tube configured for direct attachment to a gutter for conducting rainwater in a downward path, said down-tube having an upper end adjacent said gutter and an opposite lower end, said upper end being configured as a water inlet, said lower end configured as a water outlet, a spout pivotally connected at a fulcrum point to said lower end of said down-tube for articulated movement between closed and deployed positions, said spout having a dispensing tip collapsed against said down-tube when said spout is in said closed position and extended to disperse water when said spout is in said deployed position, said spout having a closed bottom defining a basin region laterally offset from said fulcrum point when said spout is in said closed position, said basin region disposed to collect a predetermined tipping volume of rainwater when said spout is in said closed position, a counterpoise operatively disposed between said spout and said down-tube for continuously applying a counterbalance force to urge said spout toward said closed position, and said down-tube including a high relief port, said high relief port extending from said lower end of said down-tube upwardly to a terminal peak, said spout partially overlying said high relief port when said spout is in said closed position, said dispensing tip disposed below said terminal peak of said high relief port when said spout is in said closed position to form a cleaning gap through which a kinetic fluid stream can directed to back-flush accumulated debris.
