Professional description of William Jackson Clock:-

“An 18^th century brass cased thirty-hour lantern clock with later arched brass dial signed W. Jackson, London, in a silver boss in the arch, the silvered dial with Roman numerals, hour hand only.

Overall height: 8 feet 3 inches (242 cms.).

The movement on four slightly tapering upright columns, plain arch enclosing bell with side fret arches intact. Crown wheel escapement, minor alterations, the whole now housed in an elegantly proportioned longcase, the domed caddy top above glazed door onto cavetto moulding over full height trunk door onto cavetto moulding onto upright rectangular base with plinth base, the whole case painted green and decorated with gilt cartouches enclosing a red field and vignettes of applied hand-coloured prints of 18^th century scenes and floral arrangements.”

The inner circle time ring contains forty-eight evenly spaced increments

or four per hour, each equal to 15 minutes. As the hour hand advances past each increment it indicates quarter past the hour, half past the hour, quarter to the hour.

I am advised by antiquarian horologist and clockmaker, Dr. Christopher Edwards;,
“With only a single hour hand you can estimate the time to within a couple of
minutes by interpolating between the quarter-hour marks.

It would have been normal to use a sundial to set the time in the first place.

When the clock was made there was little requirement to know the time to the second

or even the nearest minute.

Life was less hurried in the 18^th century!
