A LITTLE KNOWN BLACK HISTORY FACT: Alexander Miles, who - TopicsExpress

A LITTLE KNOWN BLACK HISTORY FACT: Alexander Miles, who contributed to the elevator industry, was an African-American inventor of the late 19th century who was able to transcend racial barriers in the United States. Miles attached a flexible belt to the elevator cage, and when the belt came into contact with drums positioned along the elevator shaft just above and below the floors, it allowed the elevator shaft doors to operate at the appropriate times. The elevator doors themselves were automated through a series of levers and rollers. Before working on elevator engineering, Miles experimented with the creation of hair products. The influence of his elevator patent is still seen in modern designs, since the automatic opening and closing of elevator and elevator shaft doors is a standard feature.
