Ammeter, Henry Sutton (probably), Ammeter attributed to Henry Sutton, 1883 (estimated)
... A crude scientific instrument that measures amps... instruments A crude scientific instrument that measures amps ...W.B Withers wrote of Sutton: "In the realm of science Ballarat has become of world-wide fame through the inventions by Mr Henry Sutton, a native of the place. His skill and acquirements in electricity, telegraphy, telephony, photography and also in astronomical and microscopal studies have won for him a high position as a practical scientist, and the credit is the greater as he is a self-taught student … Mr Sutton, before he was fourteen years old, had read every book on science to be found in the library of the Ballarat Mechanics' Institute." The Ballarat School of Mines (SMB) was fortunate to have this genius appointed as the lecturer-in-charge of the new Electricity and Magnetism department from 23 April 1883. Although Henry Sutton submitted his resignation to the Council of SMB in October 1884 it was resolved that he be asked to reconsider, and Mr Sutton continued to teach at SMB until the end of 1886. He was a prominent member of the Camera Club, and many of the other SMB clubs. Sutton had an active and fertile brain, and was known for his inventions, especially his work on the telephone, telephane and carbon lamps. Sutton presented a vacuum pump, worked by water jet, for use in SMB Chemistry classes. His report of 1883 states: ‘A telephonic circuit has been laid down between the [SMB] engine-house and workshops, to be used for experimental purposes.’ Henry Sutton spent much thought on artificial flight, and made some interesting experimental studies with flying birds. The storage of electricty also attracted his attention, and, after much work and thought evolved the Sutton Secondary Battery. A paper on this battery was presented to the Royal Society, London, and was afterwards printed in the 'Transactions'. Henry Sutton is listed on the Federation University Honour Roll at https://www.federation.edu.au/curator/honour-roll/honourroll_sutton.shtmlA crude scientific instrument that measures amps, with a timber base and frame. Terminal posts and sliders contacts are positioned on top of the base, with flex attached. Henry Sutton lectured at the Ballarat School of Mines (SMB) in Electricty and Magnestism between 1883 and 1886. In 1883 Sutton reported: ‘…The class has been unfortunately situated, by having to wait for instruments of precision ordered from England, but which have not come to hand. The delay has caused us to start constructing instruments, which it is hoped will bear favourable comparison with those of older date.'ammeter, henry sutton, electrical, inventor, electricity and magnetism, sutton, scientific instruments -

Instrument - Hourglass
... An hourglass or sandglass is an instrument for measuring...Hourglass or sandglass; an instrument used to measure time...An hourglass or sandglass is an instrument for measuring ...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.

Optometer Stands, Early 19th Century
... instruments to measure the separate components of vision. Dr Jules... instruments to measure the separate components of vision. Dr Jules ...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 -

This is a 33ft long tape measure and would have been used by the construction workers when building the Kiewa Valley Hydro System. The warning details (embossed into the leather covering) was to warn users to be careful not to use the tape near live electricity terminals or linkages. This tape was produced mainly for wooden structures and not electricity conductive material. This was during the 1950's to 1960's.This imperial tape measure is very significant to the Kiewa Valley as it was used in the construction of the Kiewa Valley Hydro Scheme of the 1950's-1960's. It provides evidence that small measuring equipment used in the construction and the continuing maintenance of the scheme was of the imperial measure and used by construction workers who remained and settled in the town of Mount Beauty and Kiewa Valley long after the construction period.

These instruments... and other instruments used to measure the strength of alcohol ...The firm Dring and Fage were active from 1790 to 1940 in London and were manufacturers of hydrometers and mathematical instruments they became established in London in 1790 by John Dring, who was a brass worker and hydrometer maker, and William Fage. Dring and Fage manufactured also saccharometers and other instruments used to measure the strength of alcohol. These instruments were primarily used to calculate excises. They traded at various addresses in London and they were at 56 Stamford St. between 1903 and 1938. By 1850 the company was owned by Edward Hall and Edward Jenkin and in 1940 the company became Dring & Fage Ltd, trading till the 1960s.Historically, gauging has meant measuring a volume, these gauging instruments were used by Customs and Excise and manufacturers for determining the volume and contents of liquid containers. For Customs the determination and collection of duty on imported goods which has had a very long history. Chaucer was a Customs Officer as was his father and grandfather, excise was first officially introduced in 1643, with the aim of maintaining military forces raised by the English Parliament at that time. Excise was initially a duty on home produced alcoholic beverages and soap but being easily applied, spread rapidly to a wide range of goods including imports of varying kinds. The government departments of Customs and Excise merged only in 1909 and it is from around this time that our instrument was made and used. The item demonstrates a long social history of the practice of Government's collecting duty on alcoholic beverages and thereby makes this item historically significant as it was used locally at Port Fairy by the ports Customs agents.

... An aneroid barometer is an instrument used for measuring...-and-the-bellarine-peninsula An aneroid barometer is an instrument used ...An aneroid barometer is an instrument used for measuring air pressure as a method that does not involve liquid. Invented in 1844 by French scientist Lucien Vidi, the aneroid barometer uses a small, flexible metal box called an aneroid cell (capsule), which is made from an alloy of beryllium and copper. The evacuated capsule (or usually several capsules, stacked to add up their movements) is prevented from collapsing by a strong spring. Small changes in external air pressure cause the cell to expand or contract. This expansion and contraction drives mechanical levers such that the tiny movements of the capsule are amplified and displayed on the face of the aneroid barometer. Many models include a manually set needle which is used to mark the current measurement so a change can be seen. This type of barometer is common in homes and in recreational boats. It is also used in meteorology, mostly in barographs and as a pressure instrument in radiosondes.5 inch Aneroid barometer on wooden basebarometer, aneroid -

Ship Log, 1900-1920
... of Miles, the Rocket Log is a nautical instrument for measuring... ship log rocket log mechanical ship log measuring instrument ...Thomas Walker & Son was internationally renowned in the manufacturing of ships logs. Founding father Thomas Walker (1805–1871), an engineer in Birmingham, patented a 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 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 kick starting the first of many notable innovations for the Walker family's manufacturing business. However, it wasn’t until working on an earlier ships 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 (British-based organisation promoting ties and trade with the British Caribbean) and the most common log in use for two generations. It took till 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 the time of 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 and the Walker factory was one of the first to introduce the 48 hour work week for employees. This 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. Ship Log, three analogue dials calibrated in increments of Miles, the Rocket Log is a nautical instrument for measuring a vessel’s speed and distance traveled. The floating log was drawn behind the ship over a fixed time period in order to measure the distance traveled. The counter could measure enough miles to cover the maximum distance traveled by a ship in one day. The log has two distinct parts; a brass register, made by Walker, showing the distance recorded and the rotator made by Reynolds, that spins in the water driving the counter. both parts are connected by a linked chain. The register has a cylindrical brass body approx 4.5 cm diameter containing registering mechanism with hardened steel bearings. Distance is indicated by the three pointers on enamel plate as follows: graduated every 10 miles from 0-100; every mile from 1-10; every 1/4 mile from 1/4 -1. A brass sling and eye secured to the body enables it to be attached to the taffrail. The original rotator would have had a cylindrical tapered wooden body, approx 4.5 cm in diameter with three metal alloy fins or could be all made from brass. A towing eye is fitted to the tapered end. The two pieces of apparatus are connected by a length of linked chain, length 22.9 cm."Walkers Rocket Ship-Log Birmingham (Patented)" printed on face-plate.

Instrument - Chronometer or Marine Clock, ca. 1935 to 1975
... . A chronometer is an accurate mechanical instrument used for measuring... mechanical instrument used for measuring time. It is constructed ...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.

Octant, Late 18th to mid-19th century
... : The principle of the Octant as an instrument to measure ones latitude... navigation instrument used primarily by sailors to measure ...An Octant is a doubly reflecting navigation instrument used primarily by sailors to measure the angular distance between two visible objects and was a forerunner of the sextant. The name comes from the Latin octo, or “one-eighth of a circle,” for the Octant’s arc which spans 45°, or one-eighth of a circle. The primary use of an Octant is 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. The angle, and the time when it was measured, can be used to calculate a position line on a nautical chart (latitude), for example, sighting the Sun at noon or Polaris at night (in the Northern Hemisphere) gives an angle by which the latitude can then be estimated. Sighting the height of a landmark on land can also give a measure of distance. History: The principle of the Octant as an instrument to measure ones latitude was first implemented around 1742-present but was superseded by the improvement of the octant to a sextant, a very similar instrument, better made and able to measure bigger angles 120°, allowing the measurement of Luna distances to give longitude when used with an accurate chronometer. The sextant started to appear around 1730 and 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. Henry Hemsley was a lesser-known instrument maker and optician working in London in the late 17th and early 18th century. However, it should be noted that there were two Henry Hemsley opticians and instrument makers around this period. (Henry Hemsley 1, 1786-89, who had premises at 85 Fleet St London and Henry Hemsley 2, 1828-56), whose workshop was at 135-138 Radcliff Highway London. Therefore, based on the inscribed workshop address Henry Hemsley 2 is responsible for making this example.The octant is representative of its type and although not fully complete it demonstrates how 18th and 19th-century mariners determined their latitude on a chart to navigate their way across the world's oceans in the 18th and 19th century. It also demonstrates the skill and workmanship of the early instrument makers that operated from London at this time and provided most of the navigational instrumentation use by commercial and military navies of the time.Octant, ebony wooden frame and handle.

Instrument - Barometer, Early 20th century
... A barometer is an instrument used for measuring atmosphere... Warrnambool great-ocean-road A barometer is an instrument used ...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).

Ship Log, 1900-1920
... The Excelsior IV Log is a nautical instrument for measuring... instrument for measuring a vessel’s speed and distance travelled ...The Excelsior IV Log is a nautical instrument for measuring a vessel’s speed and distance travelled. When navigating a ship it is essential to be able to estimate the boat’s speed and distance travelled to determine its position at sea. 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 speed of the vessel through the water. This was known as streaming the log and is also the derivation of the knot as a measurement of nautical speed. The Walker’s Excelsior Mark IV instrument was designed for smaller vessels, such as yachts, launches and fishing vessels. Historical: Thomas Walker & Son was internationally renowned in the manufacturing of ships logs, founding father , Thomas Walker (1805–1871), an engineer in Birmingham, patented a 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 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 kick starting 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 (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 the time of 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 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.Ship's Taff Rail Log, rope attached. Walker's Excelsior IV Log model.

Instrument - Navigational Sextant, 1882-1890
... was as an improvement over the octant, an instrument designed to measure one's... was as an improvement over the octant, an instrument designed to measure one's ...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.

Octant, Mid to late 19th Century
... An octant is an astronomical instrument used in measuring... Warrnambool great-ocean-road An octant is an astronomical instrument ...An octant is an astronomical instrument used in measuring the angles of heavenly bodies such as the sun, moon and stars at sea in relation to the horizon. This measurement could then be used to calculate the altitude of the body measured, and then the latitude at sea could also be calculated. The angle of the arms of an octant is 45 degrees, or 1/8 of a circle, which gives the instrument its name. Two men independently developed the octant around 1730: John Hadley (1682–1744), an English mathematician, and Thomas Godfrey (1704–1749), a glazier in Philadelphia. While both have a legitimate and equal claim to the invention, Hadley generally gets the greater share of the credit. This reflects the central role that London and the Royal Society played in the history of scientific instruments in the eighteenth and nineteenth century's. There were also two others who are attributed to having created octanes during this period, Caleb Smith, an English insurance broker with a strong interest in astronomy (in 1734), and Jean-Paul Fouchy, a mathematics professor and astronomer in France (in 1732) In 1767 the first edition of the Nautical Almanac tabulated lunar distances, enabling navigators to find the current time from the angle between the sun and the moon. This angle is sometimes larger than 90°, and thus not possible to measure with an octant. For that reason, Admiral John Campbell, who conducted shipboard experiments with the lunar distance method, suggested a larger instrument and the sextant was developed. From that time onward, the sextant was the instrument that experienced significant development and improvements and was the instrument of choice for naval navigators. The octant continued to be produced well into the 19th century, though it was generally a less accurate and less expensive instrument. The lower price of the octant, including versions without a telescope, made it a practical instrument for ships in the merchant and fishing fleets. One common practice among navigators up to the late nineteenth century was to use both a sextant and an octant. The sextant was used with great care and only for lunar sightings while the octant was used for routine meridional altitude measurements of the sun every day. This protected the very accurate and pricier sextant while using the more affordable octant for general use where it performs well. The invention of the octant was a significant step in providing accuracy of a sailors latitude position at sea and his vessels distance from land when taking sightings of land-based landmarks.Octant with metal handle, three different colored shades are attached, in wooden wedge-shaped box lined with green felt.

James Oddie of Ballarat has an association with Thomas Parker of Elswell-Parker. In early 1887 Oddie arrived in England seeking information on electrical knowledge and its developments. At this time Henry Sutton was teaching Electricity and Magnetism at the Ballarat School of Mines. Oddie stayed in the United Kingdom for around three years and during that time became a close friend of Thomas Parker and his family. The two first met at the first official running of the Blackpool tram, and Oddie was invited to visit Parker at Wolverhampton. Over the years Thomas Parker kept newspaper cuttings (mainly Australian) relating to James Oddie and his work. The following article is a description of the Wolverhampton works by James Oddie, and was collected by Thomas Parker. After the dinner at Blackpool, Mr. Parker visited me, and cordially invited me to see his extensive works at Wolverhampton, an invitation I was not slow to avail myself of. This was the keynote of the best friendship I made in England. I went shortly afterwards and stayed several days, visiting the works daily, as Mr. Parker gave me the run of the whole works. There I ordered the installation of a 60 light dynamo, with a 28 cell storage battery and paraphernalia, now doing duty at the Observatory. I subsequently visited the works frequently, sometimes for a week at a time, and I regard it as the brightest spot in my English constellation. Mr. Parker started his works in 1880, with one man beside himself. He never had a single day’s instruction in electricity in his life; now he daily instructs between 300 and 400 employees, who worship him as a father. He is said to be now the most practical electrical engineer and mechanist in Europe. During one of my visits I took with me an artist, who is painting for me a portrait, 6 feet by 5 feet, of Mr. Parker, surrounded by dynamos, secondary batteries, measuring instruments etc. Electric tram cars are going to be a big thing in England. Parker’s Company Limited, is now, with three other companies, in the hands of the Electric Construction Company, with Mr. Parker as manager of the lot. The whole of the works will be taken to Wolverhampton. Before I left, a tender for £50,000 was accepted for the construction of new works.AC Generator painted read and black on a stand.

Engine Dynamometer, c.1890’s
... , fitted oak case. This brass instrument is used to measure..., or dynamometer, is an instrument used on a steam engine ...The steam engine indicator, or dynamometer, is an instrument used on a steam engine (such as that of a vessel or train) to measure and record the change in the pressures of the engine’s cylinders during their operating cycle. The engineer would use it to identify problems or defects such as bad valve settings or constricted steam pipes. It could indicate the difference in efficiency caused by adjustments made to the engine, being able to instantly measure the variation of pressure from the engine stroke at any given time. This force of power would be registered by a pencil, fitted to the adjustable arm, which would trace a line on paper wound around the cylinder. The recorded information could be used in conjunction with mathematical tables. This particular instrument was made by T.S. Mc Innes, one of the better manufacturers of engine indicators. Mc Innes engine indicators were still being used in the mid 1900’s. This specific instrument was used by Mark Forsythe of North Berwial, Scotland and late of Ararat, Victoria when he was chief engineer on the “SS Talawena” in 1892. The Port of Warrnambool, in Victoria, harboured steam ships that carried both passengers and cargo along the south west coast in the late 1800’s and into the 1900’s. The engineer of a steam ship was responsible for reaching and maintaining the optimum level of steam energy to serve the locomotion and efficiency of the steam ship. The engineer would use a steam engine indicator to measure and record information to achieve this purpose. Engine Dynamometer or Steam Engine Indicator in square, fitted oak case. This brass instrument is used to measure and record steam pressure for setting up and adjusting valves on a steam engine. It has an oscillating recording drum with vertical, silver clip attached for holding paper in place around the drum. The drum oscillates left to right. There is a pulley attached to a length of cord, which is attached to the drum. Beside the drum is a fine metal arm, vertically adjustable, small hole in the end to hold a pencil. Inscription stamped into bracket of the arm. The engine indicator is mounted on a hinged side of the case that swings out ready for use. Attached chains prevent the side from opening past vertical. There is storage for other accessories and an empty compartment in the base (where a scale or ruler may have been located). The case has a collapsible wooden handle, brass hinges and two brass, hook-shaped catches. There is a code stamped inside the lid. It contains a brass, ‘T’ shaped steam-cock (or stop cock) with two open ends made of metal pipe with different sized threads. (Turning the handle on top opens and closes the space in the pipe and would close off the flow of steam from one end to the other.) Also inside the case are three different spiral springs, each with a threaded nut on the end that has a threaded hole inside it.

Today there are centr4es in over 200 ports world-wide where seamen of all backgrounds are offered a warm welcome and provided with a wide range of facilities. In Victoria the orgainsation began in Williamstown in 1857. It was as a Sailors’ Church, also known as ‘Bethel’ or the ‘Floating Church’. Its location was an old hulk floating in Hobson’s Bay, Port of Melbourne. It soon became part of the Missions to Seamen, Victoria. In the year 2000 the organisation, now named Mission to Seafarers, still operated locally in Melbourne, Portland, Geelong and Hastings. The Ladies’ Harbour Lights Guild was formed in 1906 to support the Missions to Seamen in Melbourne and other centres such as Williamstown. Two of the most significant ladies of the Guild were founder Ethel Augusta Godfrey and foundation member Alice Sibthorpe Tracy (who established a branch of the Guild in Warrnambool in 1920). The Guild continued its work until the 1960s. In 1943 a former Williamstown bank was purchased for the Missions to Seaman Club. The chapel was named St Nicholas’ Seamen’s Church and was supported by the Ladies’ Harbour Lights Guild, the Williamstown Lightkeepers’ Auxiliary and the League of Soldiers’ and Sailors’ Friends. It ceased operation in 1966. A Missions to Seamen Chapel and Recreation Room was a significant feature of ports during the late 1800s and into the 1900s. It seemed appropriate for Flagstaff Hill to include such a representation within the new Maritime Village, so the Melbourne Board of Management of Missions to Seamen Victoria gave its permission on 21st May 1979 for the entire furnishings of the Williamstown chapel to be transferred to Flagstaff Hill. The St Nicholas Seamen’s Church was officially opened on October 11, 1981 and closely resembles the Williamstown chapel. These candlestick holders are significant historically for their origin in the St Nicholas Mission to Seamen's Church in Williamstown, established in 1857 to cater for the physical, social, and spiritual needs of seafarers. It originated in Bristol, England when a Seamen's Mission was formed in 1837. The connection of the candlestick holders to the Mission to Seamen ighlights the strong community awareness of the life of people at sea, their dangers and hardships, and their need for physical, financial, spiritual and moral support.Candlestick holders or altar lights; pair of two polished brass holders.

Two of the most significant ladies of the Guild were founder Ethel Augusta Godfrey and foundation member Alice Sibthorpe Tracy (who established a branch of the Guild in Warrnambool in 1920). The Guild continued its work until the 1960s. In 1943 a former Williamstown bank was purchased for the Missions to Seaman Club. The chapel was named St Nicholas’ Seamen’s Church and was supported by the Ladies’ Harbour Lights Guild, the Williamstown Lightkeepers’ Auxiliary and the League of Soldiers’ and Sailors’ Friends. It ceased operation in 1966. A Missions to Seamen Chapel and Recreation Room was a significant feature of ports during the late 1800s and into the 1900s. It seemed appropriate for Flagstaff Hill to include such a representation within the new Maritime Village, so the Melbourne Board of Management of Missions to Seamen Victoria gave its permission on 21st May 1979 for the entire furnishings of the Williamstown chapel to be transferred to Flagstaff Hill. The St Nicholas Seamen’s Church was officially opened on October 11, 1981 and closely resembles the Williamstown chapel. These candlestick holders are significant historically for their origin in the St Nicholas Mission to Seamen's Church in Williamstown, established in 1857 to cater for the physical, social, and spiritual needs of seafarers. It originated in Bristol, England when a Seamen's Mission was formed in 1837. The connection of the candlestick holders to the Mission to Seamen highlights the strong community awareness of the life of people at sea, their dangers and hardships, and their need for physical, financial, spiritual and moral support.

THE MISSIONS TO SEAMEN (Brief History: for more, see our Reg. No. 611, Set of Pews) The Missions to Seamen, an Anglican charity, has served seafarers of the world since 1856 in Great Britain. It symbol is a Flying Angel, inspired by a Bible verse. Today there are centr4es in over 200 ports world-wide where seamen of all backgrounds are offered a warm welcome and provided with a wide range of facilities. In Victoria the orgainsation began in Williamstown in 1857. It was as a Sailors’ Church, also known as ‘Bethel’ or the ‘Floating Church’. Its location was an old hulk floating in Hobson’s Bay, Port of Melbourne. It soon became part of the Missions to Seamen, Victoria. In the year 2000 the organisation, now named Mission to Seafarers, still operated locally in Melbourne, Portland, Geelong and Hastings.

Instrument - Ship Log, early to mid-1800s
... LOGS A taffrail log is a nautical instrument used.... TAFFRAIL LOGS A taffrail log is a nautical instrument used ...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.
