  • Patent number: 4182497
    Abstract: A gutter cleaning device adapted to remove leaves and other debris from household gutters is disclosed in which a generally flat blade-like working head is connected to an elongated hollow handle. Fluid, such as water from a garden hose, is directed through the handle and into the working head whereupon it exits through a plurality of discharge openings provided in each of the sidewalls in part forming the head so as to direct a plurality of streams along the inside surface of the gutter. The device may be moved back and forth or in one direction along the gutter and in this way the fluid stream serves to loosen and/or force leaves and debris in front of the working head to accordingly enable the gutters to be so cleaned.

  • Patent number: 4174085
    Abstract: A trash bag holder which moves from a generally planar collapsed storage position automatically to an open use position in which it can be used to support a flexible wall container such as a plastic trash bag. The device includes a substantially rigid rectangular frame from which elongated support elements outwardly extend at each corner thereof. The corners are each provided with a tapered socket to receive one end of such support elements which are, in turn, connected thereto by means of an extensible cord. The support elements may thus be moved to a collapsed position generally parallel to adjacent frame elements wherein the cords are under tension and when released, will automatically move to their extended open position for receipt of a trash bag.
