Invention of the Elevator

     Back in the days of the 1850's through 1900's the invention of the elevator was a big step for civilization. The people went from old fashion stairs to for them a minute ride of luxury and realization (opposed to climbing stairs).
     An American inventor named Elisha Graves Otis was the first person to invent the mechanical elevator with adequate safety devices, such as safety brakes which gripped on to the elevator cab's rails.  Safey cables which looped around a drum that was attached to the driving motor.  These cables were made out of heavy steel instead of rope that would wear and tear within a couple of weeks or maybe possibly a month.  While on the other hand steel cables could last for a couple of years.
     Otis showed off his invention for the first time ar the Crystal Palace Exposition in
New York City in 1854.  People were estatic about the safety issue of the clamping arrangement that gripped the guide rails on which the elevator car moved when tension was released from the hoist cable.  Which meant that if by chance the hoist cable ever snapped, clamps would grip the rails to keep the elevator cab from dropping and smashing at the bottom of the elevator shaft.
     Most of the United States civilization started to like elevators.  Now that they were safer, people decided that elevators would take less time and less stress then taking the stairs.
     The first elevator was steam powered.  It wasn't until later on when elevators had and electric motor.
     A New York department store called Haughwout Department store made the news and history books in 1957 because they were the first one to have a passenger elevator, driven by steam power installed.  The store was five stories high.  Hundreds even thousands went into Haughwout a day to see and try out the new elevator.
     Soon after Haughwout installed their elevator other businesses and apartment buildnings started putting them in.
     Now that elevators are here cities could grow.  Let me tell you why, because in the cities before elevators came about apartment buildings and stores were no more than five stories high and for a valid reason.  No one would rent an apartment on the tenth floor if they had to take the stairs.  So once the elevators came around buildings began to grow up.  Think about it we wouldn't have skyscrapers because again on one would want to climb that many stairs.  No skyscrapers would put a burden on the country.  I think because a lot of people make their living by building and designing skyscrapers.  That's thousands of ...
