Description White plastic doubled sided Graviscope stored in protective leather carry case. Case is fitted with pair of press studs, pocket in front for holding instructions and is stamped "Graviscope / for / Lincoln / (Australian) / Manufactured by / Melb > W & G < Aust / R.A.A.F / Ident. No G6C/3972". Plastic graviscope consists of a 277mm white disc, printed on both sides, overlaid on one side by a 224mm disc and the other side by a 175mm disc. All discs located by central screw, to which is attached a 160mm long x 25mm wide clear celluloid strip. History / Summary The graviscope is a computing device, which in aircraft was used for measuring the centre of gravity in an aircraft. This would vary depending on crew, bomb load, fuel and stores carried. It was used in the British designed but Australian manufactured, Government Aircraft Factory (GAF) Lincoln heavy bomber, which was operated by the Royal Australian Air Force (RAAF) in the years following the Second World War. This aircraft was originally a derivative of the famous Avro Lancaster bomber. The Lincoln was used by both the RAAF and the Royal Air Force in operations against Malayan Communist terrorists during the Malayan Emergency, 1948-1960. This graviscope is of the type designed for and used by RAAF and RAF aircrew who operated this aircraft.Many by W and G Australia -

Mincer Meat, early to mid 1900's
This cast iron kitchen appliance was made in England in the early 1900's and shipped to the "colony" Australia. This was before World War II and the "growing up" of a colony to an independent member of "the British Commonwealth". It was a period when most appliances (be they household) where manufactured in England and shipped to Australian ports. It was not until the late 1960's that the Asian manufacturing giant woke up and started to dominate the market palce.This domestic kitchen appliance is very significant to the Kiewa Valley because it highlights the "made at home" period when food processing was made "in house" due to inability to source food from specialised shops e.g. the butcher or slaughter houses. It was a period before mass food processing factories were established and roads constructed up to the standard for distribution to semi remote regions such as Kiewa Valley was in the beginning of the 1900's.This cast iron (malleable iron) mincer for meat products has a large "funnel" to direct "chunks" of meat to the grinding "wheels". These "star" shaped wheels with "teeth" of three different cutting surfaces (fine, medium and coarse) provide for texture types of the final meat product. The meat is placed into the "loading" funnel and push downwards(gravity feed) through the mincing chamber and out through the front side. There is a long "screw worm" which is rotated by turning the handle. The appliance is table mounted by a vice "G" screw on clamp (hand operated).

Petrol bowser, Super Plume, c1927
The Uebergang family came from Silesia to Australia in 1848 and were early settlers in the Allansford area. The sons and other descendants also purchased farms in the area. The Percy Uebergang family lived at Tooram Park, Allansford from 1912 until 1992. Percy and Myrtle Uebergang's children were twins, Ray and Joyce born in 1926 who lived at Tooram Park until their deaths, Ray in 1986 and Joyce in 1992 after which the property was sold. Neither Ray nor Joyce married and following the death of her brother Joyce set up the Ray and Joyce Uebergang Foundation which supports the local community. The collection of items from their property was put into store for a number of years before being given into the care of the Cheese World Museum. The family often re-used, recycled and repaired items and examples can be seen in the museum. This petrol pump is part of the collection of items given into the care of the Cheese World Museum. As with many rural families the Uebergangs had bulk fuel supplies on-farm. The bowser was used to refuel farm machinery. Mobil's Super Plume petrol was one of the many brands of petrol available from the late 1920s. No electricity was required to work this bowser as it was gravity fed. The amount of petrol was selected by the position of the front lever. Petrol was then pumped into the bowl by the handle on the side of the bowser and gravity=fed to the vehicle. This petrol bowser is an example of a 1920s petrol bowser.allansford, uebergang, vacuum oil company, super plume petrol bowser, petrol bowsers, farm machinery -

Object, Synchronome Co. Ltd, Synchronome Frequency Checking Master Clock No. 2191, c1930
Information from Norman F. Dalton: Ballarat had a reticulated DC supply in the early part of last century and in 1905 had sufficient generating capacity to enable the trams to be changed from horse drawn to DC electricity. The use of electricity increased with the main power station located on Wendouree Parade, near Webster Street, under the ownership of The Electric Supply Company of Victoria. AC generating plant was installed in 1925 and conversion to AC proceeded. In 1934 the company was taken over by the State Electricity Commission Victoria (SECV) and more AC generation was installed and the changeover of customers was accelerated. This is around the time that the Synchronome Frequency Checking Mast Clock was installed at the Wendouree Parade Power Station. The SECV Annual Report of 1921 states: ::Section 11 of the act directed the COmmission to enquire into the question of securing the adoption of such standards of plant and equipment of a system, frequency and pressure for the generation and distribution of electricity as will admit of the efficient interconnection of undertakings throughout the State. In 1934 when the SECV took over the Ballarat operations the question of linking with the State grid had been a planned operation for some years but due to financial considerations had hindered it and in fact would continue to do so for a further 10 years. So while the need for close frequency control for interconnection was hardly an issue, the need to keep electric clocks correct was important, particularly as this item was a frequent sales point to cover the inconvenience and sometimes expense of converting from DC to AC. The clock is a very accurate pendulum clock with provision for varying effective length during operation for precise time regulation. There are two normal time dials and one is controlled by the pendulum and the other is operated by the system frequency. When the clock was in use it was installed by the MEter and Tests Laboratory and the time was checked daily by radio time signals. The two dials were repeated in the operators control panel in the Power Station. A maximum deviation between the two dials was set in the operating instructions (eg 5 seconds) and the operator would correct this when necessary by remote manual alteration of the turbine governor set point. The clock was used to drive and regulate a system of "slave" clocks which were used to display the time in various locations around the power station. A slave clock is a simple clock which is driven by a small electric motor, its accuracy is regulated by the master clock every 30 seconds to ensure that it and all the other slave clocks in the station are on exactly the right time; slave clocks were placed in various locations, from common rooms to workshops. A master clock could potentially run thousands of slave clocks at one plant. The clock also contains a rectifier. A rectifier is a device that is used to convert AC power to more stable DC current.Two clocks in a timber case. Both are electric, one is powered by the main pendulum mechanism, the other is a self contained electric clock. The main mechanism is of the gravity arm and roller type, which sends an impulse to the slave clocks every 30 seconds. The This Synchronome Frequency Checking Master Clock was used at the Ballarat Power Station. Below the main section of the case is a smaller cabinet containing a rectifier to provide consistent DC power for the clock. The rectifier was made by the Victorian company Hilco, which was located in Burwood. There is a high chance this is not the original rectifier from this clock as there appears to be brackets to hold a larger device in the space the rectifier occupies.Front below main clock face on front of case: "Patented Sychronome Brisbane" Lower left-hand clock face: "Frequency time" Lower right-hand clock face: "Standard Seconds" Synchronous electric clock mechanism on door (Frequency time clock): >200/250 V. 50~ >"Synchronomains" Made in England >Direction indicator for clock starting switch >"To start move lever in direction of arrow and release" >"Patent applied for" Mechanism for "standard seconds" clock: >"English Made" >"Patented" >Serial number "321" >0 above right-hand pillar on front-plate Mechanism for "standard seconds" clock: >"English Made" >"Patented" >Serial number "321" >0 above right-hand pillar on front-plate Mechanism for main clock face: >"English Made" >"Patented" >Serial number "8751" >0 above right-hand pillar on front-plate Inside case, back panel, top enamel plate: >Seconds Battery + Pos. > Battery Common or - Neg. >1/2 min dials Inside case, back panel, bottom enamel plate: external seconds dial Inside case, right hand side, electrical knobs: two switches, both "A.C. mains" Pendulum rod, below suspension spring: Serial number (?) 0000005 Rectifier in bottom cabinet: >"Hilco Rectifier" >"A.C.

Tool - Double ended spanner
The double-ended ring spanner served as a useful, manual tool for maintaining farm machinery. The hexagonal rings would be placed over a nut to secure it, before the spanner was rotated to tighten the nut. The ring design provides greater purchase, or grip on all sides of the nut, which in turn reduces the risk of rounding the nut, or slippage. Early spanners were mostly made from iron and hand-forged using an anvil and hammer. Since the mid-19th century, gravity or powered drop forging techniques were used to compress metal for greater strength. Ring spanners produced in the 20th century are mostly made of chrome vanadium steel.stainless steel, some pitting.

Postcard - photographic, Clock Tower and Infirmary, Salisbury
The Salisbury Clock Tower was built in memory of Arabella Roberts who died on 23 January 1892. The firm Smith of Derby installed the illuminated clock mechanism with four faces and was still responsible for maintenance when, in December 1970, it replaced the original gravity mechanism with a more modern movement. The original clock mechanism was sold to a customer in Providence, USA. In 1997, the new mechanism was completely refurbished and updated to include automatic adjustment for British Summer Time. At the same time the tower itself was restored, the main contractors for this work being R. Moulding and Co of South Newton. Smith of Derby continues to be responsible for maintaining the clock, and so this firm has now been providing a service to the City for over 100 years.

Functional object - Milk/cream separator
This device would separate the cream from milk using a hand operated lever. When turned, the lever would activate a disc which would spin the separator bowl at a great speed. Through this use of centrifugal force, the cream would gather in the middle while the milk would be pulled towards the outside walls of the bowl. Once the rotation ceased, the milk and cream would flow out of two separate spouts. Prior to the invention of the separator, gravity was used to naturally separate the cream from the milk. The cream rose to the top and was then skimmed by hand. This process was lengthy and often resulted in sour milk, so the invention of the mechanical separator was popular in the dairy industry as there was less waste and encouraged greater production levels.

In 1893 Harry Crowther Slingsby founded the company the family firm was at first wholesale bottlers and had established themselves in Bradford, England, later they had a branch in London. Harry Crowther Slingsby began to look into the invention of labor-saving devices for the company. He had recognised that working practices in the local factories relied heavily on manual hauling and gravity for the movement of raw materials and products from floor to floor. However, this did not solve the problem of moving items horizontally around large buildings. Slingsby then set about creating robust trucks and trolleys to move heavy loads with relative ease. Different designs were created for different purposes sack trolleys for moving large sacks of flour, sugar and dried fruit around grocery stores; high wheeled flat carts towed by one or two people; trucks fitted with wicker baskets carried fibers around textile mills and railway platform trolley to move luggage. The company is still in existence today manufacturing many different types of products.An item from the early to mid 20th century connected with railway memorabilia and a company that had humble beginnings to become today a leading UK manufacture.

Photograph of a 1926 Hudson Super 6 parked at the tea room/kiosk on the intersection of Riversdale Road and Warragul Road. Distinguishing features of the car include the triangular badge on the radiator and the unusual disc wheels. The 1926 Hudson also had horizontal radiator shutters. On this vehicle, a finer mesh has been attached in front of the shutters. This is normal practice when insects such as locusts are in plague. At the time, Warragul Road was known as East Boundary Road. Behind the car on the tramway pole is a colour light tramway signal for the single-line section between Warragul Road and the terminus. On 1 July 1928, the Wattle Park line was extended from Boundary Road via Riversdale Road to Elgar Road. It was built as a single track with a passing loop about halfway along, plus a passing loop at the former Boundary Road terminus. The tramway pole has a stop sign and a telephone box as well. In a box of negatives received is an envelope noting the car was owned by Ray Pearson and photo taken during the 1930s. Inside the motor car are two people, the driver, and a lady.

Instrument - Scale, George Salter & Co, Circa 1921
The Hughes’ Family Scale No. 48 is a spring balance scale. It uses the Imperial measurements of ounces and pounds. There are 16 ounces (OZ) in one pound (LB), and each pound equals approximately 454 grams in Metric measurements. Scales have been used to measure and compare items for value for centuries. A weight was placed on one side of a balance and the object was placed on the other. Adjustments were made to either the weight or the object until the balance was horizontal, which meant that each side was the same weight. The Salter family business began in 1760 with spring makers, Richard and William Salter. In the late 18th century, Richard Salter invented the spring scale, where the weight of an object on the tray of the scale causes pressure on a spring in the scale. The pressure caused by gravity was then measured to calculate the weight of an object. Spring scales are still used today along with the more recent and accurate digital scales. The company began manufacturing in West Bromwich, England, in 1770. The firm was taken over by William’s sons, John and George. In 1824, after the death of John, the firm became George Salter & Co. The company produced a wide variety of products, including Britain’s first bathroom scale and the first English typewriter. In 1884 the Salter Trademark of a Staffordshire knot pierced by an arrow was registered. After over 100 years of manufacturing, the company was bought out by Staveley Industries, which was bought by Weigh-Tronix, and then that company was bought by HoMedics Company in 2004.This scale was made by Salter, the company that invented the balance scale, the first British bathroom scale and the first English typewriter. The scale represents the domestic equipment used for measuring in food preparation over 100 years ago. Modern kitchen scales are still using the same principal, along with scales used in business and industry.Scale; a domestic spring balance scale for measuring weight from 0 to 20 pounds. The scale’s grey metal case has a round white dial on the front with black markings, an arrow indicator and a round shallow metal bowl on a pedestal at the top. The scale is raised on a rectangular metal base with outward-sloping sides. An adjustable screw is on the dome top. The scale is marked from 0 to 20 pounds, with each pound marked in 1-ounce increments.

Geological specimen - Chalcopyrite
This specimen was recovered from Mica Schist, Canada. Chalcopyrite is a copper iron sulfide mineral with a chemical composition of CuFeS2. Its name derives from the Greek words for copper (chalco-) and brass (pyrite). It can be found in shades of yellow, green and grey, and, when exposed to acid, it can change to purple, blue, violet and yellow tones. Weathering can cause loss of its metallic luster and its brass-yellow colour. Chalcopyrite forms under various conditions, with the most significant deposits being hydrothermal in their origin. It is known globally as the most important ore of copper for thousands of years, and is thus considered a very important mineral formation. Given its golden appearance, it is often confused for the mineral gold, earning it the popular reputation as 'fool's gold' or 'yellow copper'. However, it can be straightforwardly distinguished from gold; the latter is soft, with higher specific gravity and a yellow streak, whereas chalcopyrite is brittle, easily scratched by a nail, and has a greenish grey streak. Copper was the first metal that was used by people. It was discovered by the Neolithic man about 9,000 years ago and it gradually replaced stone as it was easier to be shaped. In Australia, search for copper began after the European settlement, leading to the discovery of substantial deposits, like the one at the Olympic Dam in South Australia, which is regarded as one of the largest copper deposits in the world. Chalcopyrite has been used for copper since smelting processes began approximately five thousand years ago. Although by no means rare, this the specimen of this mineral can be used to reflect a wider history of industrial uses of copper for a significant portion of human history. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880. A large percentage of these specimens were collected in Victoria as part of the Geological Survey of Victoria that begun in 1852 (in response to the Gold Rush) to study and map the geology of Victoria. Collecting geological specimens was an important part of mapping and understanding the scientific makeup of the earth. Many of these specimens were sent to research and collecting organisations across Australia, including the Burke Museum, to educate and encourage further study.A solid hand-sized copper iron sulfide mineral of brass yellow, often with an iridescent tarnish, with greenish-black streak and submetallic luster. Chalcopyrite can be formed in several ways, including crystalizing from accessory minerals in igneous rocks, or from magma or within volcano sulfide deposits. Most commonly, chalcopyrite are found in hydrothermal conditions, where it forms in hydrothermal veins. As a member of the tetragonal crystal system, it often takes the shape of tetra-headed crystals, often with striations along the sides of the crystals. #18 Copper pyrites/(chalcopyrite) in/Laurentian Slate/(page 315 of inventory)/page missing from/descriptive catalogue/ Other label: 81 /fool's gold, chalcopyrite, mineral, rock, geology, geological, hydrothermal, neolithic, european settlement, olympic dam, south australia, stone, deposits, specific gravity, greenish grey streak, brittle, mineral gold, metallic luster, cufes2, greek words -

Ash Wednesday Veteran This Bedford M Series tanker spent its working days at the Forests Commission depot at Gembrook, and among its many forays, fought the deadly Ash Wednesday bushfires at nearby Upper Beaconsfield and Cockatoo on 16 February 1983. Earlier in 1975, the M Series tankers underwent a design change at the Altona North workshops, replacing the cylindrical water tank with a “V” bottom 4090 litre water tank that sat low between the chassis rails to reduce its centre of gravity. Aluminium heat shields were also added to protect the pump operators on the back. While generally considered "bulletproof" the petrol fuel lines on this particular model were very prone to vaporise in the heat causing the motor to stall, often at the most dangerous moment.... in this case frightening the hell out of its driver, affable knockabout bloke, and firefighting legend Lex Wade. Some jokingly said this design quirk was an inbuilt safety feature to stop crews getting too close to the fire in the first place. The Gembrook tanker was later sent into the workshop and all its brake and fuel lines fitted with heat resistant lagging. Fortunately, this remarkable bushfire survivor was rescued from the scrap heap by Lex and fire equipment wizard Barry Marsden upon its retirement from a loyal and lengthy service. After a lick of fresh paint and most of its battle scars "buffed out", this time-honoured veteran now takes pride of place at the Altona North workshop.Bedford M series fire tankerMZF 347fire pump, fire tanker, forests commission victoria (fcv)
