发明名称 Eaves trough shield
摘要 An eaves trough shield is disclosed which is used to prevent the clogging of a downspout of an eaves trough. The trough shield portion is formed from a plurality of spaced fingers sloped over the downspout opening. At one end, the fingers are attached to a bridge-plate located at the top of the trough near the downspout of the trough. At the other end, the fingers are attached to a bottom plate which rests in the bottom of the trough away from the downspout. Flanges located at each side of the bridge-plate are used to secure the trough shield to the trough. When debris enters along the trough, it is moved to the trough shield by the action of water in the trough and deposited on the fingers. Later, after the debris has dried, it is blown off of the shield and out of the trough by the wind.
