Description: | John Lilley & Son, 9 London Street & Fenchurch Street, London
?Beecher?s | Patent?
The artificial horizon consists of a threaded brass sight-tube with a brass extension arm. The arm is fitted to the sight-tube that is shipped in a sextant telescope bracket. There is also a balance is partly submerged in a reservoir containing oil to damp the movement. The other end of the balance has a crosswire, which ensures that the sextant is held horizontally and replaces the horizon.
The instrument is contained in a fitted rectangular wooden box with a sliding lid, and a trade label for John Lilley and Son, 9 London Street and Fenchurch Street, London (1870-85).
Edward Beecher patented this artificial horizon (no. 8328 of 1896).
