John Ebsworth (died 1699) was apprenticed to Richard Ames in 1657. He worked at the Cross Keys in Lothbury but is said to have worked later at 'New Cheep Side'. He was an Assistant in the Clockmakers Company from 1682, Warden 1694-1696 and Master in 1697. See Brian Loomes, The Early Clockmakers of Great Britain, Southwick, 1981, pp.208-209.
White comments 'He seemed especially fond of centre swinging pendulums which he continued to make into the 1690s' (p.207). Brian Loomes has suggested that the purpose of separately wound trains on lantern clocks with alarms may have been to allow the user to leave the strike train unwound; an alarm clock's principal use would have been in the bedroom and therefore most owners would not want the clock striking through the night.
