ADMIRALTY, Compass Dept.

The Admiralty was a department of the Royal Navy (see WIKIPEDIA) created in 1842.  The history of the Admiralty's Compass Department is thoroughly portraited in the book Steady as she goes (A. E. Fanning, 1986). It was headed by a Superintendent of Compasses. The most famous ones were Johnson, Creak, Chetwynd, Creagh-Osborne etc. This dept. was also responsible for the aircraft compasses of the Naval Fleet until WW1.
The Board of Admiralty was abolished in 1964 and its functions integrated into the Ministry of Defence.

ANSCHÜTZ

PROFILE - Hermann (Hubert Josef) Anschütz-Kaempfe (* 3 October 1872 in Zweibrücken; † 6 May 1931 in Munich) was a German scientist and the inventor of the compass gyro (called "Kreiselapparat" in his patent DRP no. 182.855, issued 27 Apr. 1904). Since this is a gyroscopic and not a magnetic compass, we do not deal with them in this museum (see also Sperry pat. 1,279,479).
The company Anschütz & Co. was created on 28 October 1905 in Kiel and taken over by Raytheon in 1995.

Binnacle

(Description given in the late 19th c.)
A binnacle is a waist-high case or stand on the deck of a ship, generally mounted in front of the helmsman, in which navigational instruments are placed for easy and quick reference as well as to protect the delicate instruments. Its traditional purpose is to hold the ship's magnetic compass, mounted in gimbals to keep it level while the ship pitched from waves. A binnacle may be subdivided into sections and its contents typically include one or more compasses and an oil lamp or other light source. Other devices such as a sand timer for estimating speed may have been stored in the binnacle as well.
For examples see DENT, KELVIN, PLATH.

CHETWYND

PROFILE - Captain Louis Wentworth Pakington Chetwynd (b. 15 December 1866, d. 18 April 1914, Coombe Neville, Kingston-on-Thames, Surrey) was Superintendent of the Compass Dept. at the Admiralty during the early 20th C. He resumed the work of other inventors (see Crow, Creak) and patented several compass systems (see also Wrist compasses). Among his improvements was the design of a smaller compass card in the bowl. This solved the problem called the "swirl error" caused by the moving liquid during quick movements (like course changes and heeling) of the ship. He became 1912 managing director with Dent & Co. and Johnson Ltd.

CLARKE Clement

PROFILE - Clement Clarke was a famous British optician who built microscopes and various diagnostic equipment. The company was established in 1917 (Wigmore Street, London). Clarke signed Mark VI pocket compasses* probably manufactured by F. Barker & Son or some other compass maker like Dennison during WW1. In 1986 the group was acquired by Boots Plc and in 1989 was purchased by the Swiss based company Haag-Streit AG located in Berne.

 Technical Data
Dimensions (approx.): 150 x 150 x 70 mm
Additional instruments: two levels, clinometer in the lid,
- Sight: two vertical tabs with a pin-hole each in the left and right case walls. A foldable two-piece telescope. Centimeter ruler on the lower front case wall.

NOTE: This bearing compass is a (worthless) contemporary reproduction (see MISCELLANEOUS / Fakes). One can tell this by some details like the magnetic needle's bright red point and the green central jewel in the cap.  The clinometer's arrow point is also at least very unprecise.  It is highly improbable that Clarke ever produced such an antique C19th instrument.

CREAGH-OSBORNE

PROFILE - Captain Frank Osborne Creagh-Osborne (1867/1943) was Superintendent of Compasses (successor of Captn. Chetwynd) at the Admiralty and a British inventor. (more details HERE).

CREAK

PROFILE - Captain Ettrick William Creak was Superintendent of the Compass Dept. at the Admiralty. He developed in the 1880's a liquid compass that worked better than Sir William Thomson's dry card system but he was unsuccessful at his attempts to have it chosen as the Admiralty's Standard Compass because of Thomson's lobby.

CROW

PROFILE - Francis Crow was a watchmaker and silversmith of Faversham (Kent, Great-Britain). He was awarded in 1813 a patent (GB no. 3,644) for a liquid dampened compass with a lens-shaped floating card. This revolutionary idea was realized only much later (c. 50 years) by the U.S. manufacturer Ritchie.

DENT 

PROFILE - (Edward John) Dent & Co. was established in 1814. The company still exists today. Its website (www.dentlondon.com) only describes clocks and watches. See also the Dent-made Air Compass Pattern 259 designed by Capt. Creagh-Osborne.

The Pattern 24 is the earliest one, dating from around 1890/1900. It is the first model of liquid compass to be officially adopted as a service compass by the Royal Navy. It was first introduced on the early turbine torpedo boats of the time.  The pattern 24 is significant because it broke the effective monopoly that the Kelvin dry card compass had held for many years previously.

Deutsche Seewarte

PROFILE - The Deutsche Seewarte was in the late 19th and early 20th C. a department of the Admiralty of the German Imperial Navy (Kaiserliche Marine, see below: Kriegsmarine and read more in Wikipedia). Its Second  II. Department (Instrumentenprüfung) was in charge with the control of navigation instruments, i.e. also compasses, being thus the equivalent of the British Superintendent of the Admiralty of the Royal Navy.

The book Der Kompass an Bord (2. ed. 1906) comprises all necessary mathematical fomulae for the installation of compasses on board of metallic ships but also a precise description of the compass types utilised in those years, i.e.
- Thomson's (Lord Kelvin) system
- Hechelmann's improved version of Thomson's rose 
- Bamberg's fluid-dampened compass.
 This description is very similar to the entry Kompass in the famous MEYER's Konversationslexikon which is illustrated with several drawings of Hechelmann's compass rose.

Deviation Card

Since iron-hulled ships replaced large wooden ones (mid 19th C.) a correction card was necessary to steer the vessel by taking into account the magnetic influence of the metallic masses. For pictures of modern correction cards click HERE.
According to the ancient card displayed at right, the ship would have to steer SW by her compass in order to make good a course of WSW magnetic (Source: Alan Gurney, COMPASS, 2004).

DUCHEMIN

PROFILE - Emile Marin DUCHEMIN (who lived 11, rue de la Bienfaisance in Paris) filed a patent in 1874 for this compass system he had developed and called BOUSSOLE CIRCULAIRE (circular compass). This device was installed in ships for several trials at sea (1873-75) in the vessels described in the booklet (iss. 7, 1877, 47 p., photocopy available on demand). It is also listed the famous German reference book Der Kompass (Schück, 1910). The inventor tried to have his system adopted by the French Navy and produced many reports from officers with positive feedback. However, it is highly surprising that someone clang to this obviously heavy design where the Admiralties of England and Germany tried to develop the lightest solutions that could be imagined (compare to the paper rose with magnets hung on silk threads designed by Thomson, Hechelmann and C. Plath). The idea was that the larger the magnet was, the better the stability of the rose should be.



(Click on the picture above for an enlarged view of the drawing)

Short description together with the drawing on the title page: "an external magnetized circle (A) is connected with an inner magnetized circle (B) by means of a bar (C) made of aluminum or another metal. The magnetization is maximum at the North and South points and diminishes gradually towards the EAST and WEST points (n-n line)."

Pict. at r.: The magnetic circular needle.
NOTE: this instrument was in very sad condition. Its remains were glued onto a marble grip like the religious tool called monstrance. The photographs were taken at an antiques shop in Paris.

FLINDERS Bar

A Flinders bar is a vertical soft iron bar placed in a tube on the fore side of a compass binnacle (see picture at right, KELVIN compass). The Flinders bar is used to counteract the vertical magnetism inherent within a ship and is usually calibrated as part of the process known as swinging the compass, where deviations caused by this inherent magnetism are negated by the use of horizontal (or quadrantal) correctors.
It is named after Matthew Flinders (1774-1814) who wrote a report in 1812 on ships' magnetism for the British Navy.

Gimballed Compasses

Description - System probably invented by Girolamo Cardano (Padua 1501-Rome about 1570) who was among other specialties an Italian doctor and engineer. This system which was called after him in French and German (suspension à la cardan / kardanische Aufhängung) is designed to compensate for the movements of a vehicle (ship or aircraft) so that the compass card always remains horizontal (more details in Wikipedia).
Small compasses were also made for other usage. Examples : pocket compass (N & Z), tell-tale compass (Steward), box compass (N & Z), miner's compass, charm (see picture at right, copyright TML, click for enlarged view)

A gyro-compass is a... (Example: go to Anschütz)

est un dispositif à mouvement gyroscopique servant à conserver à un système indicateur de direction (rose des vents) une position stable malgré les mouvements du véhicule porteur (navire, aéronef, etc.). Certains gyrocompas peuvent être asservis à un signal émis par un senseur de champ magnétique terrestre (vanne de flux).

HECHELMANN, Georg

PROFILE - Former German compass maker (Hamburg) who patented (D.R.P. 23.503, 1874) an improved version of Thomson's (Lord Kelvin) design of a paper rose with magnets hung on silk threads (see pic. at right). He worked in his own shop from 1.10.1878 on until probably 1905 (source: Feinmechanik und Optik in Hamburg, Gert Behnke, 2011). A comprehensive description was published in the entry for Kompass in the great German encyclopedia MEYER's Konversationslexikon. This system is also described in the reference books Der Kompass an Bord (Deutsche Seewarte, 1906) and Der Kompass (Schück, 1911). His competitor C. PLATH also tried in vain to have his own system supported by the Admiralty of the Imperial Navy (Kaiserliche Marine).

KELVIN / THOMSON

PROFILE - Kelvin Hughes Ltd was formed in 1947 by the merger between the scientific instrument manufacturing firms of Henry Hughes & Son Ltd, London, England, and Kelvin Bottomley & Baird Ltd, Glasgow, Scotland. The logos of one of the preceding companies (White, Bottomley, Thomson) consisted of the three initials WBT placed on a black & white graphic resembling the yin-yang symbol (s. WBT in the section Wrist Compasses and pic. at right). 
(Read also the full story in Wikipedia - "Kelvin Hughes" and www.kelvinhughes.com)

William Thomson(later: Sir Wm. Th. Lord Kelvin of Largs) was a physicist. He invented a famous binnacle with a compass deviation correction system. He is also famous for the very special compass card he designed in 1876 and which was standard in the Royal Navy although the superiority of liquid dampened compass card was soon proven and adopted in the U.S. and other Navies (read the full story in Compass by A. Gurney and in Steady as she goes by A. E. Fanning). Both German manufacturers C. PLATH and G. HECHELMANN developed their own version of this system.
Thomson wrote a document entitled Terrestrial Magnetism and the Mariner's Compass. He also was partner in several companies which built the compasses he designed.
See also below, the booklet "Instructions for the adjustment etc."

The Thomson/Kelvin compass: The original light-weight compass card had eight magnet needles (M, see drawing at left below) but a later model improved to prevent disturbance of the compass by the engines, or by the firing of guns (patent no. 4923, 1889) possessed even 14 (pict. below at right)! The central part was cut-away and the graduated rim suspended with 32 silk threads (S) attached to the cap.

KRIEGSMARINE (German Navy)

This designation refers to the German Navy after 1935 (see note). When Germany was united to form an empire in 1871, it was called Kaiserliche Marine (Imperial Navy). The compasses used on-board the German warships featured a symbol representing the state, i.e. the imperial crown or the nazi cross (swastika) and the letter M for Marine.  
The number is the catalogue reference similar to today's NATO Stock Number.
Note: After 1918, Germany was not allowed to have military ships.
