1753458027Code 8169 Large Nautical CompassLarge magnetic nautical compass in brass and glass, England, late 19th century, signed Kelvin-White Boston-New York, mounted on a custom oak and brass board. Dimensions: 33 x 25 x 22 cm – 13 x 9.8 x 8.8 inches, compass diameter: 20.5 cm – 8.1 inches.
The compass consists of a cylindrical brass container, called a mortar, with a hard metal stem, called the sensing element, fixed to the bottom. This stem supports the compass rose, which is securely fastened, complete with a protractor circle so that the zero point coincides with the magnetic polarity.
To minimize friction, the mortar is filled with liquid, which rapidly dampens any oscillations of the assembly, and is covered with a sturdy protective glass cover. The interior of the compass features a second protractor circle from 0° to 180°.
The Kelvin-White company was born from the professional relationship between William Thompson (1824–1907), a physics professor, and James White (1824–1884), a manufacturer of optical and surveying instruments.
Thompson designed instruments, and Kelvin manufactured them.
They contributed to the first laying of telegraph cables at sea, and their collaboration lasted until Thompson's death.
William Thompson was created Lord Baron Kelvin of Largs in 1892.
In 1874, Thompson wrote an article on compasses for a magazine, which significantly boosted the demand for compasses and nautical instruments.
After White's death in 1884, Kelvin continued the business, equipping new workshops for the production of precision nautical instruments, becoming the official supplier to the Admiralty, which adopted a patented compass in 1899 on Royal Navy ships.
