Chester Pond of Brooklyn, New York was the inventor of this system in 1881. A small electric motor rewinds a spring hourly to drive the clock, being set in motion by a contact on the hour wheel. The armature of the electric motor consists of six soft iron bars set at 60 degree intervals, and the three electro magnets which move the bars round in 20 degree steps give a driving force adequate for rewinding the clock. An attempt was made to introduce the system into the United kingdom in 1886. Meanwhile in America the system was further developed and manufactured by the Self Winding Clock Company with a synchronising device operated by a signal sent every hour over the Western Union Telegraph wires.
