  • Patent number: 4602401
    Abstract: A squeegee construction is disclosed which has an elongated handle, a V-shaped frame mounted at one end of the handle, and a continuous elongated squeegee blade secured to the frame. The squeegee blade extends lengthwise along substantially the entire length of the V-shaped frame, and thus assumes a V-shape geometrically similar to the V-shape of the frame. The squeegee blade extends below the lower edge of the frame, and the lower edge of the squeegee blade is substantially coplanar over the entire width of the squeegee construction. The squeegee of the present invention is highly useful for spreading a liquid filling material into cracks in surfaces such as roofs, asphalt cement roads and driveways.
