  • Scraper with debris collecting means and associated method
    Patent number: 7814609
    Abstract: A scraping apparatus includes an elongated tubular shaft with open proximal and distal ends in fluid communication with each other along an entire longitudinal length of the tubular shaft. The apparatus further includes a funnel, a scraping implement positioned above the funnel, a mechanism for securely maintaining the scraping implement at an elevated position above the top opening of the funnel, and a top protrusion monolithically formed with the apex and situated substantially parallel to the top opening of the funnel and juxtaposed proximal thereto. Such a top protrusion has a planar top surface.
