Renaissance+and+Reformation+Invention

This invention was created by Leonardo Da Vinci for lifting and transporting pillars.The system was based on the side-sliding motion of a trolley, designed to contain the base of the pillar. A wheel operated by means of a winch set both the trolley and the large worm screw placed at the center of the device in motion. This pushed up the other end of pillar, thus lifting it. || The leather diving suit was equipped with a bag-like mask that went over the diver’s head. Attached to the mask around the nose area were two tubes that led up to a cork diving bell floating on the surface. Da Vinci's idea for Scuba gear didn’t actually become well-known until his famous Codex Atlanticus, a twelve-volume set of his drawings and notes, was published after his death. This invention helped a lot of scuba divers and people who want to see life underwater. ||
