Blonde Girl With Blue Eyes And Big Breasts Shows Off In The Elevator

In 1000, the Book of Secrets by al-Muradi in Islamic Spain described the use of an elevator-like lifting device, in order to raise a large battering ram to destroy a fortress. In the 17th century the prototypes of elevators were located in the palace buildings of England and France.
Ancient and medieval elevators used drive systems based on hoists or winders. The invention of a system based on the screw drive was perhaps the most important step in elevator technology since ancient times, leading to the creation of modern passenger elevators. The first screw drive elevator was built by Ivan Kulibin and installed in Winter Palace in 1793. Several years later another of Kulibin's elevators was installed in Arkhangelskoye near Moscow. In 1823, an "ascending room" made its debut in London.
Starting in the coal mines, by the mid-19th century elevators were operated with steam power and were used for moving goods in bulk in mines and factories In 1823 in London, an "ascending room" was built and operated by two architects, Burton and Hormer. It was designed as a tourist attraction to elevate paying customers to a panoramic view of the city. The "Teagle" - a belt-driven elevator with a counterweight was developed in 1835 by Frost and Stutt in England.
The hydraulic crane was invented by Sir William Armstrong in 1846 for use primarily at the docks of London for loading cargo. These quickly supplanted the earlier steam driven lifts as they were able to leverage Pascal's law for a much greater force. They used a plunger below the car to raise or lower the elevator. A pump applied water pressure to a steel column inside a vertical cylinder. Increasing the pressure caused the elevator to ascend. The elevator also used a system of counterbalancing so that the plunger did not have to lift the entire weight of the elevator and its load. The plunger, however, was not practical for tall buildings, because it required a pit as deep below the building as the building was tall. Later, a rope-geared elevator with multiple pulleys was developed.
