Instrument - Navigational Sextant, 1882-1890
... scientific instrument... and workmanship of the early instrument makers that operated scientific ...A sextant is an astronomical instrument used to determine latitude and longitude at sea by measuring angular distances, especially the altitudes of the sun, moon, and stars. It is a doubly reflecting navigation instrument and used mainly by sailors to measure the angular distance between two visible objects. The name comes from the Latin sextans, or “sixth part of a unit,” because the sextant’s arc can be 60° or 120° of a circle depending on the model used. The primary use was to measure the angle between an astronomical object and the horizon for the purposes of celestial navigation. The estimation of this angle is known as sighting or shooting the object, or taking a sight. This angle and the time when it was measured is used in order to determine Greenwich Mean Time and hence longitude. Sighting the height of a landmark on land can also give a measure of distance from that object. History: The development of the sextant was as an improvement over the octant, an instrument designed to measure one's latitude. The octant was first implemented around 1731-present but can only measure angles up to 45°. As larger angles were needed to allow the measurement of lunar objects - moon, stars and the sun - at higher angles, the octant was superseded by the sextant. The sextant is a similar instrument but better made and allows larger angles from 60° to 120°. This improvement allows distances to be accurately calculated thereby giving longitude when used with a chronometer. The sextant was derived from the octant in 1757, eventually making all previous instruments used for navigational positioning obsolete. The sextant had been attributed to by John Hadley (1682–1744) and Thomas Godfrey (1704–1749), but reference to the sextant was also found later in the unpublished writings of Isaac Newton (1643–1727). Earlier links can be found to Bartholomew Gosnold (1571–1607) indicating that the use of a sextant for nautical navigation predates Hadley's implementation. In 1922, the sextant was modified for aeronautical navigation by Portuguese navigator and naval officer Gago Coutinho. It should be noted that the octant and quadrant are in the same family as they were, and all are, regarded as sextants. The sextant is representative of it's type and although not fully complete it demonstrates how 18th,19th and 20th century mariners determined their latitude and longitudinal to determine their position on a chart, allowing them to navigate there way across the world's oceans. It also demonstrates the skill and workmanship of the early instrument makers that operated scientific instrument businesses from London and other areas of England to provide most of the navigational instrumentation used by commercial and military navies of the time.Sextant with square, fitted box of polished wood, "Hezzanith" brand.

Instrument - Barometer, Early 20th century
... scientific instrument... scientific instrument weather forcasting instrument weather gauge ...A barometer is an instrument used for measuring atmosphere pressure thus determining weather changes.The first apparatus generally accepted as a barometer was that set up in Florence in 1644 by Evangelista Torricelli (1608–1647), a mathematician and physicist. Torricelli filled a glass tube with mercury, sealed it at one end, and inverted it with its open end in a dish of mercury. The level always fell a short way down the tube, then settled at a height of about thirty inches. He concluded correctly that the mercury column was sustained by the weight of the air pressing on the open surface of mercury, and further experiments convinced him that the space above the mercury in the tube was a vacuum. He noted that the level rose and fell with changing temperature, but he was unable to use his apparatus to measure variations in the weight of the atmosphere because he had not foreseen that temperature would affect the level of the mercury. News of this experiment circulated quickly among European scientists, who hastened to replicate the experiment. Torricelli's conclusions were not universally accepted because some disputed whether the air had weight, while both Aristotle and the Catholic Church denied the possibility of a vacuum. In France, the philosopher René Descartes (1596–1650) seems to have been the first person, probably in 1647, to attach a graduated scale to the tube so that he could record any changes attributable to the weather. At around this time Duke Ferdinand II of Tuscany organized the first short-lived meteorological network among scientists in other Italian cities, gathering observations of pressure, temperature, humidity, wind direction, and state of the sky.Theis barometer is an example of a household item from the early 20th century, used to determine the day's weather. The barometer is significant as an aid to human social, material and scientific development.Barometer, round, brass housing inset into carved wooden casing (lacquer mostly worn off).

Instrument - Telescope, Early 18th Century
... scientific instrument... or Night Day or Night telexcope scientific instrument navigation ...This Dollond Day or Nigh telescope was designed to be used in any light conditions, as its name implies. Telescopes are optical instruments designed to make objects appear to be larger or closer. The discovery of the first telescope in 1608 can be attributed to Hans Lippershey of the Netherlands when he discovers that holding two lenses up some distance apart bring objects closer. He applies for a patent on his invention and this becomes the first documented creation of a telescope. Then in 1668, Newton produces the first successful reflecting telescope using a two-inch diameter concave spherical mirror. This opened the door to magnifying objects millions of times far beyond what could ever be obtained with a lens. It wasn’t until 1729 that Chester Moor Hall develops an achromatic lens (two pieces of glass with different indices of light refraction combined produce a lens that can focus colours to almost an exact point resulting in much sharper images but still with some distortion around the edges of the image. Then in 1729 Scottish instrument maker James Short invents the first parabolic and elliptic, distortion-less mirror ideal for reflecting telescopes. We now come to John Dollond who improves upon the achromatic objective lens by placing a concave flint glass lens between two convex crown glass lenses. This had the effect of improving the image considerably. Makers Information: John Dollond (1707-1761) London England he was a maker of optical and astronomical instruments who developed an achromatic (non-colour distorting) refracting telescope and practical heliometer. A telescope that used a divided lens to measure the Sun’s diameter and the angles between celestial bodies. The son of a Huguenot refugees Dollond learned the family trade of silk weaving. He became proficient in optics and astronomy and in 1752 his eldest son, Peter joined his father in an optical business, in 1753 he introduced the heliometer. In the same year, he also took out a patent on his new lenses. He was elected a fellow of the Royal Society in May 1761 but died suddenly in November and his share in the patent passed to his son Peter. In subsequent squabbles between Peter and the many London opticians who challenged his patent, Peter’s consistent position was that, whatever precedents there may have been to his achromatic lenses, his father had independently reached his practical technique on the basis of his theoretical command of Newtonian optics. As a result of maintaining his fathers patent, Dollond s became the leading manufacturer of optical instruments. For a time in the eighteenth and nineteenth century the word 'Dollond' was almost a generic term for telescope rather like 'Hoover; is to vacuum cleaner. Genuine Dollond telescopes were considered to be amongst the best. Peter Dollond (1731-1820) was the business brain behind the company which he founded in Vine Street, Spitalfields in 1750 and in 1752 moved the business to the Strand London. The Dollonds seem to have made both types of telescopes (reflecting and refracting), possessing the technology to produce significant numbers of lenses free of chromatic aberration for refracting telescopes. A Dollond telescope sailed with Captain Cook in 1769 on his voyage to observe the Transit of Venus. Thomas Jefferson and Admiral Lord Nelson were also customers of the Dollonds. Dollond & Co merged with Aitchison & Co in 1927 to form Dollond & Aitchison, the well-known high street chain of opticians, now fully part of Boots Opticians. They no longer manufacture but are exclusively a retail operation. John Dollond's experiments in optics and how different combinations of lenses refract light and colour gave a better understanding of the divergent properties of lenses. That went on to inform and pave the way for the improvement of our understanding of optics that is represented today. Dollond was referred to in his time as the "Father of practical optics" as a leader in his field he received many prestigious awards. The telescope in the collection is a good example of one of Dollond's early library telescopes. Its connection with one of England's 18th century pioneers in optical development makes it a significant and an important item to have within the collection.Telescope: Dollond's Telescope, Day or Night model navigational instrument.

... scientific instrument... laboratory scientific instrument norman ludbrook norman william ...The Davey Paxman Experimental Steam Engine was purchased as the result of a bequest from Thomas Bath. The 'substantial sum' was used to build an Engineering Laboratory. The Ballarat School of Mines Council minutes of 08 November 1901 record: - Plans for [the] proposed building were submitted ... and ... it was resolved that a temporary building for an Engineering Laboratory be put up.' This laboratory, as an existing building, is first mentioned in the Ballarat School of Mines President's Annual Report of 1901, presented on 28 February 1902, reporting 'the erection of a building 67ft long by 33 ft wide' This report also lists all the equipment that would be accommodated in the Engineering Laboratory, including the experimental steam engine and boiler. The experimental Davey-Paxman steam engine arrived in Ballarat towards the end of 1902. The Engineering Laboratory was opened on 14 August 1903 by His Excellency Sir Sydenham Clarke. This engineering laboratory remained in use till about 1945. By 1944 preparations were under way at the Ballarat School of Mines to expand existing facilities, to be ready for the influx of returned soldiers. A new Heat Engines laboratory was built, this time of brick construction, replacing the previous corrugated-iron shed. In the early stages the steam engine was used to drive an overhead transmission shaft for machinery in the adjacent workshop. Later the steam engine was moved to a space that became the Heat Thermodynamics Laboratory. At the end of 1969 the engine was relocated to the Thermodynamics Laboratory at the then Ballarat Institute of Advanced Education (BIAE) Mt Helen Campus. It was donated to Sovereign Hill in 2006. According to the research of Rohan Lamb in 2001 around five experimental steam engines were made by Davey Paxman, and three of these had similar configuration to the Ballarat School of Mines Steam Engine, however, each of these was also unique with different valve arrangements. The list, which was on a scrap of paper in a folio held in the Essex Archives, confirmed that one was sent to India. The Ballarat steam engine can be dated to late 1901 to early 1902. Zig Plavina was responsible for moving the steam engine to Mount Helen, and worked on it as a technician for many years. He observed the following: * The condenser is driven by the low pressure engine. * The following arrangements are possible: i) the high pressure engine alone, exhausting to atmosphere. Condenser not used, crankshaft flanges not coupled. ii) crankshafts coupled, mains pressure (120 psi) steam supplied to high pressure engine, partially expanded steam delivered to low pressure engine (Tandem operation). Choice available re exhaust steam: either to the condenser or to atmosphere. iii) crankshafts not coupled, reduced pressure steam supplied to low pressure engine. Exhaust steam - either to the condenser or to atmosphere. * Valve arrangement - a choice of Pickering cut-off or throttle governor. On low pressure engine - throttle governor only.Black and white photograph of the Davey Paxman Experimental Steam Engine.

Instrument - Chronometer or Marine Clock, ca. 1935 to 1975
... scientific instrument... navigation mechanical instrument scientific instrument ship clock ...This chronometer was made around 1936 and has been on display at Flagstaff Hill for over 40 years as part of the exhibit of the ‘Reginald M’, an Australian-built, 19ss, coastal trader vessel. A chronometer is an accurate mechanical instrument used for measuring time. It is constructed carefully to remain stable even under the changing conditions of seafaring life such as temperature, humidity and air pressure. The Master or Navigator of a ship could use the chronometer and the positions of celestial bodies to calculate the ship’s latitude at sea. In 1905 the business Chronometerwerke GmbH was formed in Frankfurt, Germany, to supply the country with high-quality mechanical chronometers and ship clocks for their maritime trade, making the country independent of other international suppliers such as those in England. In 1938 the firm was renamed Wempe Chronometerwerke. The business continues today. Its products now include its well-known chronometers, battery-powered ship clocks, ship’s bell clocks, barometers, barographs, thermometers, hygrometers, comfort meters to measure temperature and humidity, and wristwatches. The company also performs chronometer testing facilities for the State’s Weights and Measures office. The article written by Givi in July 2022 “The Basics of Marine Meteorology – a Guide for Seafarers” refers to the weather’s signs and patterns being repeated over and over, and the recording of these observations helps forecasters predict changes in the weather. The chronometer is an example of a mechanical navigational marine instrument in use in the early to the mid-20th century. The maker is significant as part of a German government initiative to be self-sufficient in the production of good quality marine technology. This chronometer is significant as part of the exhibit, the Australian-built vessel, 1922 coastal trader ‘Reginald M’, listed on the Australian Register of Historic Vessels and on display for over 40 years.Marine chronometer or marine clock, brass case, glass cover, Roman numerals, 24-hour numbers beside them.

Optometer Stands, Early 19th Century
... stands for scientific instrument... early to mid 19th Century by a well known scientific instrument ...Optometrists are trained to examine eyes and prescribe visual aids such as spectacles. The optometer pictured in the media section of this document dates from the 1800s. The optometer was used with various lenses to determine the refraction of the eye. Refraction means the extent to which light is bent by an individual's eye. The result can determine how short-sighted or long-sighted they are, and the strength of spectacles required. In the second half of the 1800s, ophthalmologists also devised instruments to measure the separate components of vision. Dr Jules Badal developed the pictured instrument in 1876. It was based on an optometer invented by William Porterfield in 1759. The brass stands look as though they were made for an optometer to be table mounted, with heavy brass stands and designed to hold a cylindrical object securely as would be required by an optometer. Stands appear to have been very well made and very early probably early to mid 19th Century by a well known scientific instrument maker given there are no inscriptions or marks to indicate the time period made or maker it is difficult to assume significance to these items at this point in time as well as the items are incomplete.The brass stands believed to be for mounting an early Optometer an (ophthalmic instrument) Noneflagstaff hill, warrnambool, shipwrecked-coast, flagstaff-hill, flagstaff-hill-maritime-museum, maritime-museum, shipwreck-coast, flagstaff-hill-maritime-village, stands for scientific instrument -

Instrument - Compass, c. 1839
... scientific instrument... OF A PIONEER The Western District in the 1840's compass scientific ...This magnetic compass is a good size to fit easily into a person's pocket or personal luggage and is protected from knocks by its wooden case. It could have been used for reference when travelling on land or sea. There is no visible manufacturer's mark, which may mean that it was not of high monetary value. Leith is a district of Edinburgh in the country of Scotland, the U.K. It was once the Port of Edinburgh and many migrant ships departed from here bound for the Australian colony. It had a busy shipbuilding industry, with wet and dry docks. It appears from the inscription on the case "Chas Gray, LEITH, 1839" that this pocket compass once belonged to Charles M. Gray (Chas is a common abbreviation for the name Charles). The inscription coincides with the name, place and date that the Western Victorian pioneer Charles M. Gray left Scotland and arrived in Australia. Charles Gray was born in Anstruther, Scotland, in 1818. His family was connected with the Royal Marines, which may have created his nautical instruments such as this pocket compass. Charles Gray arrived in Hobson's Bay on 15 June 1839 on the ship “Midlothian”. That same ship had departed from Leith, Scotland on February 15th 1839. Did Charles Gray acquire the pocket compass in Leith, perhaps as a gift or a souvenir of his motherland? Charles Gray was an early squatter and went on to become a very successful settler as a sheep pastoralist in the Western District of what is now Victoria (originally the colony of New South Wales). He and his wife had a large property called “Nareeb Nareeb”, Green Hill Creek District (now Glenthompson), Victoria, from 1840-1886. He was also a local Councillor and Justice of the Peace, and had an interest in the local indigenous people; he named his property after their tribe. Charles returned to England in 1890 and died there in 1905. Charles Gray had written an account in 1890 of his life at Nareeb Nareeb, called Western Victoria in the Forties: "REMINISCENCES OF A PIONEER The Western District in the 1840's By Charles Gray" , a valuable historical reference to colonial Victoria. His book was published by the Hamilton Spectator in 1932. Charles Gray's photograph is one of 713 historical photographs of early Victorian settlers, created as a montage by Thomas Foster Chuck in 1872. The State Library of Victoria holds the framed montage titled “The Explorers and Early Colonists of Victoria”. To qualify for inclusion on this montage the Settlers must have arrived in Victoria before 1843. Charles Gray's photograph is number 349! The pocket compass is associated with Charles Gray, one of the early squatters and settlers in Western Victoria, possibly given to him as a parting gift on his emigration to Van Diemans land in 1839. The item is very significant as it's connection with one of Victoria's early pioneers is well provenanced by the inscriptions on the wooden case. Pocket compass, brass, set into a square wooden case with hinged lid and small hook catch. Compass is marked with 360 degrees and compass points and has two pointers; one to show magnetic north and one to set the direction of travel. Hinges are triangular and inset into the wood. The lid has an attached brass plaque with the inscription "Chas Gray, Leith, 1839" (It likely belonged to Charles Gray, Leith, UK, who migrated to Port Philip Australia in 1839 and became a successful pastoralist.) “Chas Gray / LEITH / 1839” engraved on brass plaque on lid.flagstaff hill, warrnambool, shipwrecked coast, flagstaff hill maritime museum, maritime museum, shipwreck coast, flagstaff hill maritime village, great ocean road, magnetic compass, pocket compass, charles m. gray, chas gray, migrrant from leith 1839, charles gray anstruther, scottland, ship midlothian 1839, squatter western victoria, settler western victoria, hobson's bay port phillip australia, charles gray nareeb nareeb - green hill creek district, western victoria in the forties: reminiscences of a pioneer by charles m. gray 1890, leith edinburgh u.k., western victoria in the forties: reminiscences of a pioneer - montage by thomas foster chuck 1872, charles gray, reminiscences of a pioneer, the western district in the 1840's, compass, scientific instrument, nautical instrument, direction, directional compass, navigation -

Instrument - Ship Log, 1880-1890
... scientific instrument... equipment scientific instrument ship log ship log register ship’s ...The John E. Hand & Sons Company was founded in Philadelphia in 1873, quickly gaining a reputation as competent manufacturers of nautical instruments and compass adjusters. In fact, John Enos Hand, the company founder, is recognised as the first man in America to adjust a compass aboard an iron ship. The Hand Company built navigational equipment for all varieties of floating vessels, and operated a chain of retail outlets with “service stations” in numerous port cities, including Baltimore and New Orleans, until 1956. Service stations sold Hand instruments as well as other nautical paraphernalia and provided compass adjusting services. Additionally, John E Hand and his two sons, John L Hand and Bartram Hand, were inventors in their own right who patented design improvements for numerous instruments that were employed in the company’s work. Commercial and private contracts dominated the firm’s business until the late 1930s when the United States military began preparations for World War II. Although the Hand Company never completely abandoned its involvement with private industry, after World War II, military contracts monopolised their business. The Company obtained contracts with the Navy, Coast Guard and Marines to develop new instruments, and to build military-engineered nautical equipment. Of note are the wrist compass, developed for the Navy beginning in the 1950s, and the Mark VII Model 5 Navy Standard Binnacle. Although it moved numerous times, the Hand Company headquarters and factory remained in the Delaware Valley, occupying several buildings in Philadelphia and southern New Jersey. Maintaining its central office in Philadelphia well into the 1900s, the factory was moved to Atco, New Jersey around the turn of the twentieth century and subsequently to Haddon field, New Jersey. It moved one last time in the 1960s to Cherry Hill, New Jersey. In 1997, California-based Sunset Cliffs Merchandising Corporation purchased the Hand Company and all its assets for $100,000. "HAND" brand taffrail log by John F. Hand and Sons Co.

Instrument - Clock Parts, Bef. 01-06-1878
... scientific instrument... keeping device scientific instrument chronometer John Harrison ...The clock parts were discovered in 1980 by Julie Wilkins, a Victorian scuba diver who had already experienced more than 500 dives in Australia and overseas. She was holidaying in Peterborough, Victoria, and looking forward to discovering more about the famous Loch Ard ship, wrecked in June 1878 at Mutton Bird Island. The fast Glasgow-built clipper ship was only five years old when the tragedy occurred. There were 54 people on board the vessel and only two survived Julie's holiday photograph of Boat Bay reminds her of her most memorable dive. Submerged in the calm, flat sea, she was carefully scanning around the remains of the old wreck when, to her amazement, a gold coin and a small gold cross suddenly came up towards her. She excitedly cupped them in her hands and then stowed the treasures safely in her wetsuit and continued her dive. She soon discovered a group of brass carriage clock parts and some bottles of champagne. It was a day full of surprises. The items were easily recognisable, without any build-up of encrustations or concretion. Julie secretly enjoyed her treasures for twenty-four years then packed them up for the early morning train trip to Warrnambool. After a short walk to Flagstaff Hill Maritime Museum and Village. Her photograph was taken as she handed over her precious find, she told her story to a local newspaper reporter, lunched a café in town then took the late afternoon train home. Her generous donation is now part of a vast collection of Loch Ard shipwreck artefacts, including the gold watch and the Minton Majolica model peacock. This group of brass clockwork parts is incomplete. The pieces were in the ocean for over 100 years before Julie recovered them from the Loch Ard wreck. Their size would suit the works of a carriage clock, with a mainspring and weight to power the clock movement, a pendulum to measure the clock's speed, arbours, posts, pillars and at least one other plate. They would have been mounted inside a protective case with a small door to easily access the clock face for setting the time and accessing the key's winding hole. The clock cases were usually made from decorative gilt brass with a glass front and a carrying handle. The parts include a weighted second hand with a decorative four-pronged finish at one end, a rounded weight at the other, and a hole for attaching it to the clock face. The gear teeth profiles are ‘cycloidal’, an arch shape with vertical sides, which is common for antique clocks. Modern clockworks have ‘involute’ teeth with sloping sides and a squared-off top. The brass carriage clock parts are an example of a mechanical clock produced in the 1870s. The clock's design is a part of the chain of technological improvements in methods for timekeeping. Its cycloidal gear teeth were the forerunner of the more modern involute gears. The group of clock parts includes a weighted hand or arm for signifying the seconds. This feature was uncommon in portable Victorian-era clocks. The clock parts are also significant for their association with the ill-fated sailing ship Loch Ard, wrecked in 1878. The travelling clock or officer’s clock may have been part of the cargo destined for the 1880 Melbourne Exhibition, or the personal possession of one of the people on board the vessel. Brass clockwork parts from a mechanical clock, sixteen pieces. Parts comprise a plate, large gears or wheels, small pinions or wheels with fine teeth, wheels with cogs, and a weighted second hand. The parts were from a carriage clock ca. 1878. They were recovered from the wreck of the sailing ship Loch Ard.flagstaff hill maritime museum and village, warrnambool, great ocean road, shipwreck coast, loch ard, wreck of the loch ard, 1878, mutton bird island, peterborough, scuba diver, 1980s, shipwreck artefact, relic, clock, mechanical, clock parts, time, timekeeper, horology, chronometry, cogs, time keeping device, scientific instrument, chronometer, john harrison, longitude, carriage clock, coach clock, portable clock, travelling clock, travel clock, traveller’s clock, officer’s clock, weighted second hand, victorian era, cycloidal gear teeth, brass clock, julie wilkins -
