Several early examples of sound-recording and reproducing machines are here, too. Some of America's earliest typewriters are exhibited in chronological sequence. Locks, keys, bolts, and other hardware remarkable for their artistry are also on view.

Highlights include:

  • mechanical clocks dating from the 14th century
  • atomic clocks
  • one of Thomas Edison's first phonographs (1877)
  • Emile Berliner's 1888 gramophone
  • the Victor Talking Machine
