Plural Blade Patents (Class 30/172)
  • Patent number: 5809602
    Abstract: A window scraper has a drum that mounts four blades on its periphery, the blades extending generally tangentially so the sharp edges project beyond the drum. A shroud covers the drum and blades, and the shroud defines an opening where the blades project through the opening to engage a glass pane to be scraped. Switch actuators are placed beside the opening so the opening must be urged against a surface before the drum can be rotated. The motor and battery may be placed within the handle of the scraper. A safety shield is pivoted to the shroud, and can be used to cover the opening in the shroud when the scraper is not is use.

  • Patent number: 4477972
    Abstract: A tool, primarily for use in stripping asphalt and wood shingles from a roof, has a flat base plate the front edge of which is provided with a transverse series of teeth and which includes a rearwardly and upwardly extending portion providing a transverse fulcrum. A handle is anchored to the handle and includes a portion spanning the fulcrum zones and anchored to the base plate adjacent the teeth. The handle defines with the base plate an included angle such and the length of which and the shape of which is such that the user can readily force the base plate under a group of shingles and pry them, together with nails, from the roof easily and safely while working from a nearly erect, comfortable position whether the shingles are to be stripped starting from the top of the roof, the eaves, or working from side-to-side of the roof.
