A foghorn is a device that uses sound to warn of navigational hazards like rocky coastlines, or boats of the presence of other vessels, in foggy conditions. The term is most often used with marine transport. When visual navigation aids such as lighthouses are obscured, foghorns provide an audible warning of rocky outcrops, shoals, headlands, or other dangers to shipping. An early form of fog signal was to use a bell, gong, explosive signal or firing a cannon to alert shipping. From the early 20th century an improved device called the diaphone was used in place of these other devices, The diaphone horn was based directly on the organ stop of the same name invented by Robert Hope-Jones, creator of the Wurlitzer organ. Hope-Jones' design was based on a piston that was closed only at its bottom end and had slots, perpendicular to its axis, cut through its sides, the slotted piston moved within a similarly slotted cylinder. Outside of the cylinder was a reservoir of high-pressure air. Initially, this air would be admitted behind the piston, pushing it forward. When the slots of the piston aligned with those of the cylinder, air passed into the piston, making a sound and pushing the piston back to its starting position, whence the cycle would be repeated. This method of producing a low audible sound was further developed as a fog signal by John Northey of Toronto and these diaphones were powered by compressed air produced by an electric motor or other mechanical means that admitted extremely powerful low-frequency notes. The example in the Flagstaff collection is an early cased and portable diaphone used on pleasure or sailing craft. By manually turning the crank handle air is produced and fed into valves that direct air across vibrating metal reeds to produce the required sound. in foggy weather, fog horns are used to pinpoint a vessels position and to indicate how the vessel is sailing in foggy conditions. One blast, when sailing on starboard tack and two blasts, when sailing on a port tack and three dots, when with wind is behind the vessel. Since the automation of lighthouses became common in the 1960s and 1970s, most older foghorn marine installations have been removed to avoid the need to run the complex machinery associated with them, and have been replaced with an electrically powered diaphragm or compressed air horns. The example in the collection is significant as it was used in the early 19th century for sailing vessels was important but these portable crank fog horns have also been superseded by modern electric varieties. Therefore the item has a historical connection with sailing and maritime pursuits from our past.English Rotary Norwegian Pattern nautical foghorn within a boxed pine varnished case with exposed corner dovetailing, original leather carrying strap, brass side crank, and original copper trumped horn.

In times past the only way to measure a ship’s speed was to throw a wood log into the water and observe how fast it moved away from the ship. In the 16th century, the log was fastened to a rope knotted at set intervals. The log was thrown over the stern (back) of the vessel and a crew member counted the number of knots that were paid out in a set time. From this, they could estimate the vessel's speed through the water. This was known as streaming the log and is also the derivation of the knot as a measurement of nautical speed. Various manufacturers of nautical equipment had sought over the years to perfect the operation of determining a ship's speed and it wasn't until Thomas Walker and his son Ferdinand developed a mechanical system that eventually made this task became easy for marine navigators. Thomas Walker & Son were internationally renowned in the manufacturing of ship logs the founding father, Thomas Walker (1805–1871), an engineer in Birmingham, patented his mechanical log in 1878 which was a recording instrument that attached to a rail at the stern of a vessel connected by a long cord with a rotor which was towed behind the ship. The instrument dial then recorded the distance travelled. Thomas Walker first went into business to manufacture stoves at 58 Oxford Street Birmingham. Walker’s self-feeding stove was widely lauded at the Paris Exhibition of 1855, winning a prize medal and kickstarting the first of many notable innovations for the Walker family's manufacturing business. However, it wasn’t until working on an earlier ship’s log model invented by his Uncle that Thomas Walker became interested in the further development of this device, used to ascertain a ship’s speed. Walker continued to improve on the common log for the company of Massey & Sons and these improvements were deemed revolutionary. This log became a firm favourite of the West India Association (a British-based organisation promoting ties and trade with the British Caribbean), being the most common log in use for two generations. It took until 1861 for Thomas Walker and his son, Thomas Ferdinand Walker (1831-1921) to patent the first Walker log of many. Together, with the introduction of the A1 Harpoon Log two years later, they established the Walker Log Business as a force to be reckoned with. By his passing in 1871, Thomas Walker Snr had not only founded a family business with considerable staying power but also instilled a tradition of public service. Having sat as a representative on the Birmingham Town Council for 15 years and played an active role in public works, he was soon given the nickname of ‘Blue Brick Walker’. Much like his father, Thomas Ferdinand Walker changed the face of the maritime industry. His patent of 1897, the ‘Cherub’ log, was a notable departure from the past providing a far more accurate reading and replacing the majority of logs of the age. They were the first to produce an electric log (Trident) and the Walker factory was one of the first to introduce the 48-hour work week for employees.The ship log was invented and made by a significant marine instrument maker and innovator of machinery. It demonstrates the huge leap taken to improve navigational accuracy at sea with an instrument that was in use for decades.Ships Log, Walker Trident electric motor, in wooden box with instructions inside box.

Its design is similar to an earlier brass fog horn used on a marine vessel, as it has a wide brim that allows it to be free-standing, and a shoulder rope makes it portable and frees up the user's hands. The narrow end is shaped into a mouthpiece. The megaphone may have been used at sea foghorn on a vessel, although it has no reeds for the sound, or used by a leader of a band or a fireman or other similar uses. This megaphone's conical shape is based on the centuries-old ram's horn or horn from other animals, used to amplify sound to make it travel a long distance or be heard above other sounds. It represents a similar instrument made in the 19th century and used as a signal or to give instructions, such as on a vessel at sea, to a lifesaving team, or in a marching band. Megaphone; brass conical shape with an opening at both ends and a join near the wide end. The wide opening has a broad brim and is painted red inside. A brass ring is attached near each opening and a narrow rope is attached to each ring. warrnambool, flagstaff hill maritime museum and village, fog horn, marine equipment, navigation, warning signal, maritime, nautical, fireman, captain, shoulder rope, signal, safety equipment

Negretti and Zambra 1850-1980s were optical instrument makers and mathematical instrument makers based in London, England. The firm of Negretti and Zambra was established in 1850 by Henry Negretti and Joseph Zambra who had formed a partnership. Their skill was immediately apparent when exhibiting at the 1851 Great Exhibition at Hyde Park, they were the only English instrument makers to receive a prize medal for meteorological instruments, resulting in their appointment as instrument makers to the queen, Greenwich observatory, and the British Meteorological Society. In 1853, when the Crystal Palace was re-erected in Sydenham, Negretti and Zambra became the official photographers of the Crystal Palace Company, which allowed them to photograph the interior and grounds of the new building. The firm made use of this access to produce a number of stereographs. Between 1855 and 1857 Negretti and Zambra commissioned photographer Pierre Rossier to travel to China to document the Second Opium War. Although Rossier subsequently was unable to accompany to Anglo-French forces in that campaign, he nevertheless produced a number of stereographs and other photographs of China, Japan, the Philippines and Siam (now Thailand), which Negretti and Zambra published and that represented the first commercial photographs of those countries. In 1856 Negretti and Zambra sponsored a photographic expedition to Egypt, Nubia and Ethiopia conducted by Francis Firth. In 1864 Negretti and Zambra (themselves) photographed Shakespeare's House at Stratford on Avon. A sepia photograph was then pasted onto card 4" × 2.5". This was then presented to visitors to the Crystal Palace to enable them to compare it with the model erected by Mr E. T. Parr in the Centre Transept. The card itself is headed "Crystal Palace April 23rd 1864." That year they also published a book, titled A Treatise on Meteorological Instruments, (which was reprinted in 1995). Throughout World War One Negretti and Zambra were entirely engaged in the production of various instruments for the Ministry of Munitions. They developed many instruments for the Air Ministry including a mercury-in-steel distance thermometer for taking the oil and air temperatures in aircraft which was patented in 1920. In 1946 the company went private and in 1948 the company was made public, and by 1950 Negretti and Zambra had 821 employees in Britain. In order to increase production and to safeguard future development in 1964, they purchased a modern factory at Aylesbury for all their production. In 1981 Negretti and Zambra were taken over by a group of financial institutions in the form of Western Scientific Instruments and in 1985 the company was acquired by Meggitt Holdings.The subject compass is just one type of the many marine and scientific, optical items this company produced over it’s life time.

This representative example demonstrates a mariner’s astrolabe. Historical examples are rare. There are less than one hundred known to exist and most of these have been recovered from shipwrecks, many from Spanish and Portuguese vessels. An astrolabe is a measuring device once used to navigate the seas by observing the sun and stars to measure their altitude. The measurement of altitude could then be used to calculate the ship’s latitude but at that time in history there was no means of measuring longitude. The body of the navigational astrolabe was cast brass and much heavier, and less complicated than the variety used on land. The heavier weight and cut-away shape reduced the effect of the wind and waves when trying to use it at sea. A mariner’s astrolabe or ‘star finder’ is a simplified version than that used by Arabic astronomers to find the altitude of the sun and stars above the horizon, and time of the sunrise and sunset. It is a forerunner to the quadrant, octant and sextant and was popular for about 200 years over the 1500s and 1600s to find the latitude of a ship at sea. The user held the astrolabe at eye level and, usually with assistance, aligned the stars through the two small sights (pinnules), then read the altitude indicated by the pointer on the arm. It could also be used to sight the sun by holding it lower down, aiming it at the sun, and adjusting it until the sun shone through both pinnules. This astrolabe is an example used to demonstrate the mariner’s astrolabe, which was navigational tool of the 1500s and 1600s, in the time before longitude was able to be determined. It is a forerunner to modern navigation technology. Mariner’s astrolabe – a representative example. A gold painted, disc shaped object with cut outs and revolving arm in centre.

First State Watch Factory: This factory was founded in 1930 under orders from Joseph Stalin, the "First State Watch Factory" was the first large-scale Soviet watch and mechanical movement manufacturer in the USSR. Via its USA-based trading company (Amtorg), the Soviet government bought the defunct Ansonia Clock Company of Brooklyn, New York in 1929, and the "Dueber-Hampden Watch Company of Canton", based in Ohio. The soviets moved twenty-eight freight cars full of machinery and parts from the USA to Moscow in order to establish the factory. Twenty-one former "Dueber-Hampden" watchmakers, engravers and various other technicians helped to train the Russian workers in the art of watchmaking as part of the Soviet's first five-year plan. The movements of very-early products were still stamped "Dueber-Hampden, Canton, Ohio, USA" (examples of these watches are very collectible today). In 1935 the factory was named after the murdered Soviet official Sergei Kirov. During the second world war, as the Germans closed in on Moscow in 1941, the factory was hurriedly evacuated to (Zlatoust USSR). By 1943 the Germans were in retreat, and the factory was moved back to Moscow, adopting the "First Moscow Watch Factory" name. In 1947 the first wristwatches under the brand name "Pobeda" and the first Marine Chronometers and Deck watches were produced. By 1951 the production of wristwatches had increased to 1.1 million. In 1975 new machinery and equipment for manufacturing complex watches were imported from Switzerland. The first chronograph called "Okean" (3133) was produced for the space station "Soyuz-23."The Chronometer is of recent manufacture and an excellent example of the type of instrument used to navigate the seas in the 19th century. It is of good quality and of a type regarded as very accurate and well made. The maker, First Watch Factory, has a dept that is still producing the "8916" standard Chronometer for horologists and collectors.

The ship's log part, called a fish, is likely to be from a mechanical taffrail log system. It was recovered from the wreck site of the barque, the 1840-1852 Grange. There are no marks on the fish to identify its maker or model. It is part of the John Chance Collection. This ‘fish’ is part of an early to mid-1800s ship's log. It would likely have been part of a taffrail log connected to a rotor (also called propeller, spinner) by a strong line, and the other end connected by a line to a dial mounted on the taffrail, or stern rail, at the stern of the vessel. As the propeller rotated through the water it would spin the log, which in turn would cause a number to register on the dial, showing the current speed in knots; one knot equals one nautical mile per hour. TAFFRAIL LOGS A taffrail log is a nautical instrument used for measuring the speed of a vessel, providing vital navigational information to be calculated, such as location and direction. A log has been used to measure the speed of a vessel since the 1500s. A simple piece of wood was tied to a long line and thrown into sea at the back of the vessel. The rope was knotted all along at equal distances apart. On a given signal the log line was pulled back into the vessels, the knots counted until the log came up, then the figures were calculated by a navigator In 1802 the first successful mechanical log available for general use was invented by Edward Massey. It had a rotor 'V' section connected to a recording mechanism. The water’s movement rotated the rotor, which intern sent the movement to the recorder. There are examples of this invention available to see in some of the maritime museums. Thomas Walker, nephew of Edward Massey, improved on Massey’s design, and Walker and his son took out a patent on the A1 Harpoon Log. In 1861. Both Massey and Walker continued to improve the designs of the taffrail log. New designs were still being introduced, even up to the 1950s. THE GRANGE, 1840-1858- The wooden barque ’Grange’ was a three-masted ship built in Scotland in 1840 for international and coastal trade. On March 22, 1858, the Grange set sail from Melbourne under Captain A. Alexander, carrying a cargo of ballast. The barque had left the Heads of Phillip Bay and was heading west along the Victorian coast towards Cape Otway. The ship struck Little Haley’s Reef at Apollo Bay due to a navigational error and was stuck on the rocks. The crew left the ship carrying whatever they could onto the beach. Eventually, the remains of the hull, sails and fittings were salvaged before the wreck of the Grange broke up about a month later. About 110 years later, in 1968, the wreck of the Grange was found by divers from the Underwater Explorers Club of Victoria. They were amazed to find a unique, six to nine pound carronade (type of small cannon) and a cannonball on the site. There have been no other similar carronades recorded. In that same year the anchor of the Grange was recovered by diver John Chance and Mal Brown. The ship’s log is significant historically as an example of hardware used when building wooden ships in the early to mid-19th century. The ship’s log is historically significant as an example of the work and trade of blacksmith. The ship’s log also has significant as it was recovered by John Chance, a diver from the wreck of the Grange in the 1968. Items that come from several wrecks along Victoria's coast have since been donated to the Flagstaff Hill Maritime Village’s museum collection by his family, illustrating this item’s level of historical value. The ship’s log is historically significant for its association with the 1840s wooden barque, the Grange. The Grange is an historical example of a Scottish built vessel used for international and coastal trader of both cargo and passengers in the mid-19th century. The Grange is an example of an early ship, designed with a wooden hull. It is significant as a ship still available to divers along the south coast of Victoria, for research and education purposes. The Grange is an example of a mid-19th century vessel that carried a weapon of defence onboard. Ship log fitting, called a fish; part of a brass navigational instrument, likely to be from a taffrail log. The metal is a tan colour and has rough surface with a sheen, and discolouration in places. Its basic shape is a hollow cylinder with ends tapering to a smaller size. In the centre there are opposing openings cut out, showing a rough texture inside. One end on the cylinder is closed with a ring and shank installed, fixed by an embedded screw through the end of the cylinder.

An hourglass or sandglass is an instrument for measuring a defined time and can be used perpetually by simply turning it over immediately the top bulb empties. The clear blown glass is shaped into two equal sized bulbs with a narrow passage in the centre and contains uniform sized sand or glass particles in the lower bulb. The width of the neck regulates the constant flow of the particles. The glass is held in a stand with top and bottom of equal shape and size. Hourglasses can measure an infinite variety of time by gauging the size of the particles, the shape and size of the bulbs and the size of the passage between the bulbs, thus measuring hours or minutes or even seconds. Generally an hourglass sits between discs of wood at the ends, which are joined by long wooden spindles between the ends and tightened by screw caps. The length of time can be adjusted by adding or removing sand particles. The use of the marine sandglass (or hourglass) has been recorded in the 14th century in European shipping. A one minute sandglass was used in conjunction with the ship’s log for ‘dead reckoning’, (see below) that is, for measuring the ship’s speed through the water. They were also used to regulate ringing the ship’s timetable; for example a 4 hour sandglass was used for the length of the sailors’ watch, and a half hour timer for taking of readings for the ship’s log; the ship’s bell would be rung every half hour. It was usually the role of the cabin boy to watch and turn the sandglasses over at the exact time of them emptying their upper chambers and to ring the ship’s bell. Hourglasses have been used historically for many hundreds of years. Some have been used for timing church sermons, in cooking, in industry and at sea. Even today they are used for measuring the cooking time of eggs and timing a player’s turn in games such as Boggle and Pictionary. The sandglasses at sea were gradually replaced in the late 1700’s to early 1800’s by the more accurate chronometers (marine clocks) when they became reliable instruments. DEAD RECKONING (or Deduced Reckoning) Dead reckoning is the term used to describe the method of calculating the ship’s position from its speed and direction, used in early maritime travel, mostly in European waters. Both the (1) speed and the (2) direction of travel were recorded on a Traverse Board at half-hourly intervals during a helmsman’s watch of 4 hours. The navigator would record the readings in his ship’s log, plot them on his navigational chart and give his updated course directions to the next helmsman on watch, along with the cleared Traverse Board. This was a very approximate, but none-the-less helpful, method of navigation. The wooden Traverse Board was a simple pegboard with a diagram of a compass with eight peg holes along the radius to each of the compass points, plus a grid with ascending half hours in the left column and increasing ship’s speed in knots in a row across the column headings, with a peg hole in each of the intersecting cells. A number of wooden pegs were attached to strings on the board. By placing one peg consecutively in the direction’s radius hole, starting from the centre, and the speed holes when the half hourly reading was taken, a picture of speed and direction for the whole 4 hour watch was created. (1) To measure the ship’s speed a one minute hourglass timer was usually used to measure the ship’s speed through the water and help to calculate its longitude. A rope, with knots at regular standard intervals and a weight such as a log at the end, would be thrown overboard at the stern of the ship. At the same time the hourglass would be turned over and a seaman would start counting the number of knots on the rope that passed freely through his hands as the ship travelled. When the timer ran out the counting would be stopped. A timer of one minute (one-sixtieth of an hour), knots spaced one-sixtieth of a nautical mile apart, and simple arithmetic easily gave the speed of the ship in nautical miles per hour ("knots"). This would be recorded every half hour. The speed could however be inaccurate to the travel being affected by ocean currents and wind. (2) To calculate the ship’s direction a compass sighting would be recorded each half hour.Marine hourglasses or sandglasses were used from around the 14th to 19th century during the time of sailing ships. This hourglass is representative of that era, which is during the time of the colonisation of Australia. Hourglass or sandglass; an instrument used to measure time. Two equal sized clear glass bulbs joined with a narrow passage between them, containing equal sized particles of sand grains in lower bulb.
