Roberto Gualelli looks at his model of Leonardo Da Vinci's pile driver, on view at the Edison Museum in Dearborn, Mich. In Da Vinci's original sketch, a weight, raised by a hand-operated winch, was released automatically when it reached a certain height, dropping with great force upon the wooden stake driving it into the ground. This is a modification of the type commom at Da Vinci's time. Mr. Guatelli has constructed 68 models of mechanical devices designed by Da Vinci. -- (January 19, 1950.)
