Abstract: This paper is to deal with chart drives, the mechanism which companies rely upon to turn the charts on their various recording instruments. The chart drives are expected to be reliable, accurate and simple to operate. Chart drives as known to the gas and oil industry have seen many changes over the years they have been used. In the infancy days of recording instruments over 100 years ago, the chart drive came into existence. The first chart drives were manufactured by the Seth Thomas Clock Factory. Thomas at the time manufactured the escapement mechanisms for mantle and grandfather clocks. Bristol, one of the first recording instrument manufacturers, contracted Seth Thomas to produce a modified clock which could be used as a chart drive, thus the emergence of the chart drive as we know it today.
