Who Invented Elevator Safety Brake ?
Answer: B
Elisha G. Otis invented it.
His device of 1852 used a wagon spring that engaged ratchets on the guide rails the moment rope tension was lost. He demonstrated it at the New York Crystal Palace in 1854 by having the rope cut while standing on the platform.
