ELEVATOR BRAKE
Elisha Graves Otis (1811-1861) invented the elevator brake, which greatly improved the safety of elevators. He used a ratchet on a spring to catch the elevator in the event of an accident (like a broken cable). -
umbrella
Samuel Fox (1815 - 1887), an English inventor and manufacturer, invented the steel ribbed umbrella in 1852 (the ribs of the umbrella hold the fabric in place - wood or whale bone had been used as ribs before Fox's invention). Fox started the "English Steels Company," which manufactured his new umbrella. -
X-RAY
X-rays were discovered in 1895 by Wilhelm Konrad von Roentgen (1845-1923). Roentgen was a German physicist who described this new form of radiation that allowed him to photograph objects that were hidden behind opaque shields. He even photographed part of his own skeleton. X-rays were soon used as an important diagnostic tool in medicine. Roentgen called these waves "X-radiation" because so little was known about them. -
TELEPHONE
The telephone (meaning "far sound") is the most widely used telecommunications device. It was invented in 1876 by Alexander Graham Bell (with Thomas Watson). Bell patented his invention on March 1876 (patent No. 174,465). His device transmitted speech sounds over electric wires, and his idea has remained one of the most useful inventions ever made. -
IRON, ELECTRIC
The electric iron was invented in 1882 by Henry W. Seeley, a New York inventor Seeley patented his "electric flatiron" on June 6, 1882 (patent no. 259,054). His iron weighed almost 15 pounds and took a long time to warm up. -
RECORD
Records, used to record sound, were invented in 1877 by Thomas Alva Edison, who invented the first machine to record and play back sounds (the phonograph or record player). Early records were cylindrical, but flat disks soon replaced them.
