Lot Essay

Thomas Buckney's pendulum, Patent No.9358, 5 August 1895. The rod is composed of tubes of steel and zinc with a central steel rod. The cylindrical lead bob has a calibrated rating nut to the underside.

Thomas Buckney Junior (1838-1900) read a paper On the Superiority of Zinc and Steel Pendulums to the Royal Astronomical Society in 1886. He quoted various experiments where a zinc and steel pendulum proved more efficient in responding to temperature changes than mercurial counterparts. See Vaudrey Mercer Edward John Dent and His Successors, The Antiquarian Horological Society, 1977, pp.49-491 and Plate 98.
