  • Ice scraper
    Patent number: 4141111
    Abstract: An ice and snow scraper adapted to be held in the hand of a user is disclosed. The scraper comprises a one-piece body having a hand-fitting handle section, a blade section, and an intermediate section. The blade section comprises a scraping surface and an oblique ice-deflecting surface. The intermediate section is curved so as to displace the blade section below the plane of the handle section. This scraper shape facilitates the application of force longitudinally of a surface to be scraped with the hand of the user remaining spaced from that surface while ice is deflected substantially away from the hand of the user and the blade is oriented at the optimum scraping angle.
    Type: Grant
    Filed: June 20, 1977
