  • Publication number: 20020014025
    Abstract: A filtering gutter or trench cleaning device with directional fluid exit is advantageous in the cleaning process. The invention includes an open scoop like structure with two sides that are connected by a bottom portion and a rear portion. At least one of these portions includes a directional vent that allows water to exit as the debris stays within the structure. The directional capacity of the vent includes a void angle that directs the flow of water. If the water is desired to be removed in this manner as well as the solid debris, while the device is empty, a liner can be inserted into the exposed cavity, thus enabling a water tight seal within the cavity. The bottom portion in the front of the invention can also include a plurality of teeth extending from the bottom portion, away from the rear portion.

  • Patent number: 5536406
    Abstract: A drain filtering device is disclosed. The improvement over the prior art is comprised of reducing the filter size from an elongated device that spans the length of the gutter system to a modular unit which is necessary only at the drain sight. The invention also includes an inclined upper face which is positioned on the upstream side of the drain in the gutter and a down spout attachment which locates the invention in the gutter such that the flow of filtered water passes through the invention and into the downspout. The debris that collects in the gutter is carried along the with the water until it makes contact with the inclined upper face and is forced up the incline until the overflow debris flows over the side of the gutter thereby cleaning same and preventing the downspout from becoming clogged.
