发明名称 Eavestrough downspout
摘要 A automatic downspout is taught having an extension which swings, in response to passage of water through the downspout, between a storage position and a position for transport of water. The extension has connected thereto a reservoir for retaining an amount of water from the water passing through the downspout. The weight of the water retained by the reservoir acts to maintain the extension in the lowered position for a selected period of time after the passage of water through the downspout stops. An actuator for such an automatic downspout is also taught.
