Elisha Otis’s Elevator Patent Drawing, 01/15/1861.
Item From: Records of the Patent and Trademark Office. (1849-1925).
Patent Spotlight. Elisha Graves Otis was the founder of the Otis Elevator Company. While living in Yonkers, New York, he invented a safety device that prevented elevators from falling when their hosting cable failed. He also is famous for a safety elevator demonstration he did at the New York Crystal Palace during the 1854 New York World’s Fair. To the crowd’s consternation, he had the rope holding his platform severed by an axeman… only to fall a few inches before safely coming to a halt.
