Brushing Up With His Invention (Aug, 1941)

Brushing Up With His Invention

DON LEVERIDGE, 22-year-old senior of the University of Chicago, demonstrates his revolving toothbrush, which uses a hand-operated crank as its power source. The young lady is using an ordinary toothbrush which, according to Don, is old-fashioned in the light of his invention. He has already talked 200 of his fellow students into using his type of brush, and has great hopes for marketing it nationally.

    A year or so later they came out with the steam-powered version and he was out of business.
