摘要： A method of connecting a down spout extension to an eave trough down spout. Firstly, pivotally connect a down spout extension to a lowermost end of an eave trough down spout such that the down spout extension is movable between a substantially vertical stored position and a substantially horizontal operative position. Secondly, position a spring at the connection of the down spout extension and the eave trough down spout biasing the down spout extension into the stored position. The spring tension is set such that a flow of water through the down spout provides a force to overcome the biasing force of the spring thereby moving the down spout extension to the operative position.

摘要： An automatic eaves trough downspout includes a first conduit and a second conduit. The first conduit has a coupling socket. The second conduit has a hollow cylindrical coupling body is adapted to fit in the socket to form a pivotal connection. A pair of pivot pins serve as an axle for relative pivotal movement of the first conduit and the second conduit. A torsion spring overlies at least one of the pivot pins to bias the second conduit into a substantially vertical stored position. A ratchet engagement is provided between the pivot pin and the socket of the first conduit, which permits rotational movement pin in the first direction to increase spring tension and resists rotational movement in the second direction.
