Electric and synchronous clocks

Alexander Bain patented the electric clock in 1841, and through the later nineteenth century electricity was used both to drive pendulums and to distribute time. Master clocks sent impulses every half-minute or minute to subsidiary ('slave') dials across factories, schools, railway stations and post offices; Matthäus Hipp's toggle (1842) kept pendulums swinging with minimal interference. William Hamilton Shortt's free-pendulum clock (1921), with a slave pendulum doing the mechanical work, became the most accurate mechanical clock ever made in series.

In the 1920s and 1930s synchronous motor clocks, which count the alternating-current cycles of the mains supply (50 or 60 Hz), arrived in homes; Telechron in the United States and Smiths 'Sectric' and Ferranti in Britain made them in great numbers. Battery clocks such as the Bulle, Eureka and ATO used electromagnetic impulsing of balances or pendulums.
