Megger as the device was called, is in fact its brand name. It is a device that supplies a DC (direct current as per car batteries) voltage to enable testing of electrical apparatus. This particular device produces 250volts DC when the handle is turned vigorously. If an electrical device, such as a kettle or toaster, blew a fuse or tripped a circuit breaker, when switched on, then it must be checked electrically before any more use. Following the repair of the faulty item a megger would be used to check if either of the AC 240volt plugs leads were touching the metal case (earth). The output leads of the megger would be connected with one to the earth (metal case) and the other to each of the power connections in turn. A good megger reading of 50,000 ohms (resistance) would enable the device to be returned to service. A reading of zero ohms resistance would mean that it would again blow a fuse, and was therefore unsafe to use. In the electrical industry e.g. the former State Electricity Commission, a megger would be used to test lots of similar item in sequence. Because of the vigorous job of winding the handle, two persons were often used to save time. One would crank madly whilst the other shifted the leads. This particular megger is of a small voltage, but other meggers are bigger and have a few ranges of DC voltages able to be selected. The optimal megger for large Generating machines was motor driven megger. This was applied to the device being tested for a duration of approximately 30 minutes with reading of the resistance taken at regular intervals.All equipment belonging to the State Electricity Commission of Victoria was labelled with a metal plaque attached to it. The SECV constructed the Kiewa Hydro Electric Scheme in the Upper Kiewa Valley and on the Bogong High Plains. The scheme began in 1938 and finished in 1961 when this megger was used and also possibly later as the SECV remained to maintain and operate the Scheme. This megger is of significance in relation to the advancement of technology.A rectangular box in dark brown bakerlite casing.

Black powder splitting guns were commonly used to split large logs into more manageable pieces before the advent of excavators and front-end loaders in bush logging operations. A typical splitting gun used in Victorian forests was a piece of high-grade steel about 1-1/2 to 2 inches in diameter and about 16 inches long, and slightly tapered at one end. They had a ¾ inch hole drilled about 9 inches deep into the centre of the shaft with a small pilot hole drilled from the outside to load the fuse. The tube was carefully loaded with an amount of black gunpowder using a funnel and spoon. Experience being the guide on how much powder to use, which depended on log size, species and difficulty of splitting the wood. The hole was stopped with a piece of wadded paper and the gun positioned at the end of a length of the log to be split. The splitting gun was then belted into the log with a large wooden maul or even the back of an axe to a depth of about 3 to 4 inches. There were often markings as a guide. This also had the effect of tamping the black powder inside the gun. Preferably the gun was backed up by another large log to absorb the shock and avoid it flying off in the bush somewhere. I have seen guns where a length of string and coloured flag could be attached to help find them. A length of fuse was then inserted in the small hole and lit. Kaboom !!!! Needless to say, the splitting gun was a dangerous implement.Commonly used to split pulpwood but now rareBlack Powder Splitting GunFive marking rings used to guide how far the gun was in the logforest harvesting

Potassium permanganate is an inorganic chemical compound with the chemical formula KMnO4. Formerly known as permanganate of potash or Condy's crystals, it is a strong oxidizing agent. It dissolves in water to give intensely pink or purple solutions, the evaporation of which leaves prismatic purplish-black glistening crystals. c1859 London chemist Henry Bollmann Condy had an interest in disinfectants; he found that fusing pyrolusite with sodium hydroxide (NaOH) and dissolving it in water produced a solution with disinfectant properties. He patented this solution, and marketed it as 'Condy's Fluid'. Although effective, the solution was not very stable. This was overcome by using potassium hydroxide (KOH) rather than NaOH. This was more stable, and had the advantage of easy conversion to the equally effective potassium permanganate crystals. This crystalline material was known as 'Condy's crystals' or 'Condy's powder'. Potassium permanganate was comparatively easy to manufacture.A brown glass bottle with a red plastic topped cork stopper for 'Tromax' , 'Purple Crystals' ie Permanganate of Potash , that was used as an antiseptic and disimfectant.TROMAX BRAND / PURPLE CRYSTALS/ or Permanganate of Potash / (Poisonous )/ For Household and Medicinal Uses / 2oz. / TROMAX / A PRODUCT OF/ SIGMA Co.Ltd. / MANF.

This protection relay apparatus (a large electrical fuse), which permits the easy monitoring and disconnection of faulty electrical apparatus connected to the large SEC Victoria Hydro Scheme's electrical power producing generators. These generators are powered by the hydro force of "stored" water at a higher altitude. The establishment of both the NSW and Victorian Hydro Schemes was achieved from the early 1900's to the 1960's. At this point in time the need for additional power sources to quench both an industrial and domestic demand for electricity was purely an economic and not and environmental (carbon reduction) factor. This hydro scheme was instigated by "the Government of the day" as a bold move and was the major force of the World War II refugee and "technical" workforce inclusion of skilled and unskilled migration into the Australian environment. Although this mass "invasion" of workers with families was thought of in some circles as intrusive, the expansion of population post war years and its integration into the Australian rural sector, produced the multi- lingual multi-cultural diversity of later years.This protection relay is very significant to the Kiewa Valley as its use was introduced during the Kiewa Hydro Scheme. Although only a small apparatus it was part of the explosion of human resources into the valley. This influx of population transformed the region from that of a basically quiet rural region to one which evolved into both an industrial and a larger residential community. This evolution in the valley created a change, not only in the "physical" landscape but also the socio-economic expansion which permitted other "tourist" based industries into the valley.This protection relay unit has a black painted metal shell with four copper enclosed "prongs" fastened to the rear of the housing(from a bake-lite plate) . Between these "prongs" are four "empty" points allowing additional "screw on" bases. The front glass enclosed meter and recorder allows for the identification and automatic disconnection of any faulty equipment connected to the main power generator. This equipment acts similarly to a modern day circuit breaker found on the electrical circuit boards of residential homes.On the top section of the front panel "ASEA" to the left "Made in Sweden" and to the right "Frabrique en Suede" below this "RIS" below this a graph and next to it two columns of numbers and a pointer for each setkiewa hydro electricity scheme, victorian state electricity commission, relays, generators

The ceramic insulators were used by the PMG to insulate telephone lines connecting to the lightstation accommodation. The installation of a single galvanised wire telegraph line in 1873 provided the lightstation with a vital link to the outside world via Morse code. In 1875, the Australasian Sketcher reported on the new facility, writing that ‘the lighthouse on the extreme point of the promontory is connected with Melbourne by a line of telegraph, and as a large number of vessels pass in sight of the lighthouse, useful information is gained respecting their movements’.The system was immobilised in 1885 when a thunderstorm caused some of the poles to explode and connection wires to fuse and turn into molten metal. During WWII the lighthouse line was upgraded to four copper wires, and in 1971 a radio link replaced the line. The lines required constant maintenance. Some poles remain along the length of the promontory’s Telegraph Track as reminders of this former communication link. Insulators can also be found in the collections at Cape Schanck; Cape Otway and Gabo Island. Comprises a white ceramic insulator attached to a rectangular metal plate.

Electric kettles were invented by the English to speed up tea preparation. In Australia fancy ceramic electric jugs quickly became a status symbol. During the Great Depression era anyone who could offer you a cuppa from a beautiful Electric Kookaburra Jug was considered to be doing well. Made by Nilsen Porcelain Australia in the 193Os, these kettles were unique for their charming art deco bird shape. Nilsen Electric Kookaburra Jugs are now regarded as a classic Australian icon prized by collectors. Oliver John Nilsen was born in Collingwood, Victoria in 1894. In 1916 he began his own electrical business, Oliver J. Nilsen & Co. (later Oliver J. Nilsen (Australia) Ltd). Nilsen's manufactured goods included such diverse products as transformers, bearings, battery chargers, bells, buzzers and gongs, porcelain ware, fuses, insulators and neon signs. Nilsen Porcelain Australia was a smaller company within the Nilsen group. Nilsen still operates as an electro-technology company operating throughout AustraliaThis jug is an excellent example of art deco ceramic appliances of the 1930s to 1950s on both a local and national level. It is also representative of products developed by a major Australian manufacturer.

The origin of the fusee is not known. Many sources credit clockmaker Jacob Zech of Prague with inventing it around 1525. The earliest dated fusee clock was made by Zech in 1525, but the fusee appeared earlier, with the first spring-driven clocks in the 15th century. The idea probably did not originate with clockmakers, since the earliest known example is in a crossbow windlass shown in a 1405 military manuscript. Drawings from the 15th century by Filippo Brunelleschi and Leonardo da Vinci also show fusee mechanisms. The earliest existing clock with a fusee, also the earliest spring-powered clock, is the Burgunderuhr (Burgundy clock), a chamber clock whose iconography suggests that it was made for Phillipe the Good, Duke of Burgundy about 1430. Springs were first employed to power clocks in the 15th century, to make them smaller and portable.[1][5] These early spring-driven clocks were much less accurate than weight-driven clocks. Unlike a weight on a cord, which exerts a constant force to turn the clock's wheels, the force a spring exerts diminishes as the spring unwinds. The primitive verge and foliot timekeeping mechanism, used in all early clocks, was sensitive to changes in drive force. So early spring-driven clocks slowed down over their running period as the mainspring unwound. This problem is called lack of isochronism. Two solutions to this problem appeared with the first spring-driven clocks; the stack freed and the fusee. The stack freed, a crude cam compensator, added a lot of friction and was abandoned after less than a century. The fusee was a much more lasting idea. As the movement ran, the tapering shape of the fusee pulley continuously changed the mechanical advantage of the pull from the mainspring, compensating for the diminishing spring force. Clockmakers empirically discovered the correct shape for the fusee, which is not a simple cone but a hyperboloid. The first fusees were long and slender, but later ones have a squatter compact shape. Fusees became the standard method of getting constant force from a mainspring, used in most spring-wound clocks, and watches when they appeared in the 17th century. Around 1726 John Harrison added the maintaining power spring to the fusee to keep marine chronometers running during winding, and this was generally adopted. The fusee was a good mainspring compensator, but it was also expensive, difficult to adjust, and had other disadvantages: It was bulky and tall and made pocket watches unfashionably thick. If the mainspring broke and had to be replaced, a frequent occurrence with early mainsprings, the fusee had to be readjusted to the new spring. If the fusee chain broke, the force of the mainspring sent the end whipping about the inside of the clock, causing damage. The invention of the pendulum and the balance spring in the mid-17th century made clocks and watches much more isochronous, by making the timekeeping element a harmonic oscillator, with a natural "beat" resistant to change. The pendulum clock with an anchor escapement, invented in 1670, was sufficiently independent of drive force so that only a few had fusees. In pocketwatches, the verge escapement, which required a fusee, was gradually replaced by escapements which were less sensitive to changes in mainspring force: the cylinder and later the lever escapement. In 1760, Jean-Antoine Lépine dispensed with the fusee, inventing a going barrel to power the watch gear train directly. This contained a very long mainspring, of which only a few turns were used to power the watch. Accordingly, only a part of the mainspring's 'torque curve' was used, where the torque was approximately constant. In the 1780s, pursuing thinner watches, French watchmakers adopted the going barrel with the cylinder escapement. By 1850, the Swiss and American watchmaking industries employed the going barrel exclusively, aided by new methods of adjusting the balance spring so that it was isochronous. England continued to make the bulkier full plate fusee watches until about 1900. They were inexpensive models sold to the lower classes and were derisively called "turnips". After this, the only remaining use for the fusee was in marine chronometers, where the highest precision was needed, and bulk was less of a disadvantage until they became obsolete in the 1970s. Item is an example of clock mechanisms used until 1910 for many different styles of clocks and went out of fashion in the 1970s due to improvements in clock and watch making.Brass fusse clock movement, It has very heavy brass plates and wheels, high-count machined pinions, and a fusee. The mounting of the pendulum is missing and It has a recoil escapement. A fusee is a conical pulley driven through a chain by the spring barrel. As the spring runs down, the chain acts at a larger and larger radius on the conical pulley, equalising the driving torque. This keeps the rate of the clock more even over the whole run. It has motion work to drive an hour hand as well as a minute hand and the centre arbor is extended behind the back plate to drive some other mechanism.Inscription scratched on back"AM 40" flagstaff hill, warrnambool, shipwrecked-coast, flagstaff-hill, flagstaff-hill-maritime-museum, maritime-museum, shipwreck-coast, flagstaff-hill-maritime-village, clock mechanism, fusee mechanism, horology

Human beings appear to have been making their own ceramics for at least 26,000 years, subjecting clay and silica to intense heat to fuse and form ceramic materials. The earliest found so far were in southern central Europe and were sculpted figures, not dishes. The earliest known pottery was made by mixing animal products with clay and baked in kilns at up to 800°C. While actual pottery fragments have been found up to 19,000 years old, it was not until about ten thousand years later that regular pottery became common. An early people that spread across much of Europe is named after its use of pottery, the Corded Ware culture. These early Indo-European peoples decorated their pottery by wrapping it with rope, while still wet. When the ceramics were fired, the rope burned off but left a decorative pattern of complex grooves on the surface. The invention of the wheel eventually led to the production of smoother, more even pottery using the wheel-forming technique, like the pottery wheel. Early ceramics were porous, absorbing water easily. It became useful for more items with the discovery of glazing techniques, coating pottery with silicon, bone ash, or other materials that could melt and reform into a glassy surface, making a vessel less pervious to water. https://en.wikipedia.org/wiki/CeramicThe discovery and development of ceramics in numerous shapes, form and materials, revolutionised the world.White ceramic container, glazed with single groove around circumference near lipNoneflagstaff hill, warrnambool, shipwrecked-coast, flagstaff-hill, flagstaff-hill-maritime-museum, maritime-museum, shipwreck-coast, flagstaff-hill-maritime-village, ceramics

The Bofors 40 mm gun, often referred to simply as the Bofors gun, is an anti-aircraft/multi-purpose autocannon designed in the 1930s by the Swedish arms manufacturer AB Bofors. It was one of the most popular medium-weight anti-aircraft systems during World War II, used by most of the western Allies as well as by the Axis powers. The shells were manufactured according to a British design after it was discovered that the Swedish shells had much too sensitive a contact fuse, "which functioned on impact with rain drops". Although the shells could nominally reach out to 11,000 yards (10,000 meters), almost all the shells manufactured had self-destroying tracers that detonated the rounds at a range of 4000-5000 yards (3700-4600 meters.) This helped prevent friendly fire incidents or other collateral damage. In addition to the TNT bursting charge, the shell contained a pellet of powdered magnesium and aluminum as an incendiary. Production of ammunition peaked at 12 million rounds per month in the winter of 1944. Ammunition type Contact fused HE/incendiary fixed shell. AP shells were also available.

A butter churn is a device used to convert cream into butter. This is done through a mechanical process, via a crank used to manually turn a rotating device inside the barrel shaped churn. The agitation of the cream, caused by the mechanical motion of the device, disrupts the milk fat. The membranes that surround the fats are broken down, subsequently forming clumps known as butter grains. These butter grains, during the process of churning, fuse with each other and form larger fat globules. Air bubbles are introduced into these fat globules via the continued mechanical action of the churn. The butter grains become more dense as fat globules attach to them while the air is forced out of the mixture. This process creates a liquid known as buttermilk. With constant churning, the fat globules eventually form solid butter and separate from the buttermilk. The buttermilk is then drained off and the butter is squeezed to eliminate excess liquid and to form it into a solid mass. Then rinsing could be done simply by washing in water, followed by draining, salting and working or "kneading" the butter with a pair of wooden butter pats, or with bare hands. This is a paddle churn, a barrel that contains a paddle, which is operated by a handle. The paddle churned the butter inside the container when the handle was turned. Early settlers had to be self sufficient, growing their own vegetables, making tools and clothing and usually had a house cow to produce their milk supplyThis domestic butter churn is an example of the skill of the pioneer craftsman, carpenters and tool makers c1900. As pioneers and early settlers had to be self sufficient they usually kept a dairy cow or 'house cow' to provide milk for drinking and for butter and cheese to made by the family.A small wooden, domestic butter churn with a lid and a crank that manually rotated the paddle inside.

Assay is a process of metallurgy and chemical analysis used to determine proportions of precious metals in ores and other metallurgy substances such as silver or gold. The process helps identify pollutants present within a sample and can indicate a high level of pollution in a mining site. Stoneware crucibles are used in the fire assay process due to their ability to withstand high temperatures. Fire assay is a three step process where by samples from the mine are ground in a find powder and then mixed with dry powder chemicals. This mixture is heated in a crucible to extreme temperatures (crucible fusion) until all of the powers fuse into a glass like slag. Once this reaction is complete, the contents are poured into a mold and cooled. In step three (known as cupellation) the mixture is separated in a fire assay cupel and once this is complete the cupel with reveal a small bead of precious metals. Established by George Guthrie in 1857 (about 5km north of its current site) and then again seven years later in 1864 after it initially closed, Bendigo Pottery remains one of the most influential and longest running potteries in Australia. Over the years the Pottery has contributed to the growth and development of the district through both its products including building products, table ware and decorative and commemorative war as well as artistically, being responsible for training and supporting many potters locally.

The clock was purchased from Jas Murray & Co. of 107 Bourke Street East, Melbourne by Francis Barnard. James Murray & Co were well known clock and watchmakers operating from premises in London with branches in Calcutta and Melbourne. They were watchmakers and jewellers in Melbourne from 1860 to 1888. Francis Barnard established Barnard’s Pharmacy on the corner of Bulleen Road (later renamed High Street) and Cotham Road in 1857. In the early 1860s, after purchasing the clock, he placed it in his pharmacy where it could be seen by passers by. When he relocated across the road to 49 Bulleen Road (now 167 High St.) in 1880 he took the clock to the new premises. He maintained the accuracy of the clock so that local residents consulted it for the correct time, even after the Post Office building with its clock tower was opened in 1888. When Francis Barnard retired, his son took over the pharmacy. In 1925, the Barnard Pharmacy was sold to David Paton. The Paton’s were at first puzzled why people constantly peered in the door until they realised that the timepiece was the drawcard. When David Paton died in 1941, his widow sold the pharmacy but took the clock with her to her new florist shop at 145 High Street. When Mrs Paton retired in 1953, she took the clock to her home in Boronia. In 1973 her daughter donated the clock to the Kew Historical Society.Significant locally to Kew as an example of a timepiece that was used by the local community during the 19th century to tell the time.Barnard’s clock is a typical wall clock of the nineteenth century, variants of which could be seen in shops, offices, public buildings and stations. It has a mahogany case with a moulded wooden bezel encasing a hinged brass bezel housing the glass face which protects the dial and hands when working. The clock face has an off-white hand painted tin dial with black painted Roman numerals. The hands are black painted metal; the hour hand has a wide spade shaped point whilst the minute hand is much thinner. ‘Jas Murray & Co’ is painted above the centre, with ‘107 Bourke Street East’ and ‘Melbourne’ below, with the key hole in between. The clock movement is a fuse chain attached to a brass mainspring barrel which powers the pendulum for eight days. This is housed within a rectangular wooden casing with a convex curved base housing a hinged door giving access to the pendulum which is attached to the back of the clock by four wooden pegs.Jas Murray & Co / 107 Bourke St East / Melbournefrancis barnard, f g a barnard, high street - kew (vic), pharmacies - kew (vic), clocks, paton's pharmacy --- kew (vic.), bulleen road -- kew (vic.)

This electroplated silver teaspoon was made by the Sheffield Silver Plate & Cutlery Company Limited from about 1913 to early-1930s. It was recovered from an unknown shipwreck in the coastal waters of Victoria in the late 1960s to early 1970s. The shipwrecks in the area range from around the 1840s to the early-1930s. It is part of the John Chance Collection. Sheffield manufactures produced high quality silverware products. In the mid-1700s a cutler, Thomas Boulsover, invented a process to fuse copper between two sheets of silver, which could still be like solid silver then the edges were bound in silver. Items made this way are now referred to as Old Silver Plate. The modern method of electroplating has a much thinner layer of silver. The firm Sheffield Silver Plate and Cutlery Co. Ltd. was established in 1913 by Mappin & Webb to make spoons and forks using the American Wilzin process, which was a failure. In 1923 the company was incorporated then re-financed and reverted back to the older production method for electroplating. The maker’s stamp usually had the letters “S.S.P. & C. Co Ltd EPNS” and often included an octagon stamp with “SSP”. The firm had the registered trademarks of ‘SILCUTA’ and ‘SILTONA’ and has also used the name ‘Sheffield Nickel & Silver Plating Co. Ltd.’ The firm had manufacturing Works at Priestley Street, Sheffield from 1913 until the 1960s. They also had a London office in 1919 at Atlantic House, 40a Holborn Viaduct, London, E.C.1., then in 1921 at Union Bank Buildings, Charterhouse Street, E.C.1. The company was dissolved in 2000, the last office address being 23 Albemarle Street London, W1S 4AS. Although this spoon is not linked to a particular shipwreck, it is recognised as being historically significant as an example of cutlery, possibly from a passenger’s luggage or imported for use in Colonial Victoria in the 19th to early 20th century. The spoon is the only example in Flagstaff Hill’s collection that is connected to the manufacturer Sheffield Silver Plate and Cutlery Co. Ltd., historically significant also, as in 1939 the same manufacturer was a recognised supplier to the British Government. The spoon is also significant as it was recovered by John Chance, a diver in Victoria’s coastal waters in the late 1960s to early 1970s. Items that come from several wrecks have since been donated to the Flagstaff Hill Maritime Village’s museum collection by his family, illustrating this item’s level of historical value.Spoon; teaspoon, nickel plated silver, discoloured to brown.

The Forests Commission developed the use of helicopters for aerial ignition from the mid 1960s. Bryant and May at Richmond worked with the Commission to develop a Delayed Action Incendiary Device. DAIDs as the were known, had an overall length of 180 mm, striker end length - 10 mm. Ignition end length - 80 mm, then a layer of high melting point wax (to prevent accidental ignition when rubbing together in transit). Both ends coated with a modified match head compound with safety fuse exposed length between coated match ends. There was a 17-second delay from when the small end was struck to an intense flaming of the large end, which lasted for 40 seconds. DAIDs were dangerous so were stored in a metal box outside the helicopter along with a disposable striker patch attached with a quick release pin to a special half-door. The first test was with a Bell 47G on 4 October 1967 and the first use, anywhere in the world, of DAIDs to backburn a large bushfire was undertaken in north eastern Victoria in February 1968. There was a crash of an FCV helicopter conducting aerial ignition near Wandiligong on 19 April 1978 with the tragic death of two forest officers and their pilot. The crash led to the immediate end of the use of DAIDs and the adoption of the safer Premo ping-pong ball incendiary machine which originally came from Canada but was modified at the Altona workshops. Overall, the development of aerial ignition techniques by the Forests Commission from the mid-1960s resulted in a steady climb in the area burnt each year…. peaking at 477,000 ha in 1980-81 and with an impressive 10-year rolling average of 220,000 ha around the time of 1983 Ash Wednesday Bushfires.Developed in Victoria for aerial ignitionLarge double ended match used for aerial ignition and back burning by dropping from a helicopterbushfire, forests commission victoria (fcv)
