Abstract

An anti-clogging and debris removal device is positionable to cover the opening in an open-topped, elongated gutter member so as to maintain the gutter member free from the flow-obstructing effects of leaves, twigs or other debris. The anti-clogging and debris-removal device includes rollers securely positioned adjacent each of the distal longitudinal ends of the gutter member, a continuous, endless, mesh-like conveyor belt trained for rotation about the rollers, and a selectively actuatable drive assembly for selectively rotating the rollers to longitudinally move the endless conveyor belt so as to transport leaves, twigs and other debris which collect on the conveyor belt to one of the distal ends of the gutter. The conveyor belt is of a width substantially equal to the width of the gutter member to prevent debris from entering the gutter between the gutter member and the edge of the belt. The drive assembly is preferably a DC motor, but other mechanical alternatives, such as a crank and pulley or a wind-activated propeller can also be employed.
