Cable Car |
Cable
cars are a popular way of traveling up and down the hilly streets of San
Francisco, California.
Cable
cars were invented in 1873 by Andrew S. Hallidie, an American manufacturer of
wire cables. At that time, most American
cities had horse-drawn buses. But the
streets of San Francisco were too steep for horses to climb with heavy loads.
Hallidie
placed an endless steel cable in a slot under the street. Large underground motion turned wheels that pulled
the cable along the slot. A
car could be moved by means of a grip which extended down through the slot to
the moving cable.
When
the grip man pulled back on a lever the grip seized the cable and the car was
pulled along on steel tracks. These
little cars still rattle over the crest of Nob Hill and other streets as a
reminder at earlier times.-Dick Rogers
