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).

Five of a collection of slides donated by Laurie Dixon. Water was pumped from Candowie Reservoir to nearby Almurta Basin and gravity fed to Wimbledon Heights Storage Basin. These open water basins were two main components of the water distribution of the day and supplied the area from 1964 to 1989. The Almurta and Wimbledon Heights Storage Basins were decommissioned in 1999 when the San Remo Basin was improved an now is the vital link in the transfer of water from Candowie via the Purification Plant.Five of a collection of slides taken by Laurie Dixon.

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

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.

See 16mm film footage of vintage aircraft VH UIU and VH UMA, Both aircraft are bi-planes with folding wings. The engines are mounted upright. The gravity supply petrol tanks are fixed amidships to the top wing. The straight wings, shape of the rudders, the wheels and configuration of the undercarriages all suggest to me that both aircraft are DH60 CIRRUS MOTHS that would have been built from 1925 to 1929. The exhaust pipes, which are mounted on the left side, (later to be moved by de Havilland to the right side) may suggest that the two aircraft in the film may be closer to 1925. VH UIU may be found from 0 to 58ft and VH UMA from 185ft to 26ift. for Description

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.

Majority of Galena in Australia is found in hydrothermal deposits emplaced around 1680 million years ago which have been heavily metamorphosed. Galena is the natural mineral form of lead sulfaide. It occurs generally as fine to large crystals due to syntectonic remobilization at low temperatures and moves to a suitable location. The colour is a shining lead and silvery gray with high specific gravity between 7.2 and 7.6 gms/cm3 and contains 86.6 lead sulfaide in its purest form. Its cyrstal system is cubic with perfect cleavages, and contract penetration and lamellar twinning. This particular specimen is from the Broken Hill mine, it is one of the largest lead mines located in Western New South Wales and still has ore reserves amounting to 20.9 million tonnes of ore grading of 7.4% lead, 9.4% zinc, and 61.5 million oz of Silver. Throughout its history, it has produced over 200 million tonnes of ore throughout its 127 years of mining history dating back to 1885. Galena mineral ore found in Australia is considered rare, as it is only currently found in the Broken Hill Mine of Western New South Wales. It represents heritage value through the systematic collecting of the geological surveyers in Victoria and Australia during the early to late 19th Century. The fact that it is only found in one mining area of Australia, shows that this specimen is rare for examples of Australian Galena. This mineral specimen is one part to a larger collection, aquistion, and distribution of Garnet in Galena around Australia and parts of the world and donated to the Burke Museum between 1860-1880. While this specimen was not found by the Victorian Geological Survey, it shows the historical need for mapping geological areas around the Gold Rush region to further identify areas of precious metal and gem aquisition. Additionally, collecting these specimens was an important part of mapping the scientific make up of the earth's surface. Many were sent to institutions for further contribution to research and scientific knowledge of the specimens.

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. In the background is part of the tea rooms located at this corner with a Shell gravity-fed petrol bowser. At the time, petrol was not sold at Service Stations on a Sunday - Sunday trading laws, but they allowed Tea Rooms or kiosks to be open.Yields information the intersection of Warragul and Riversdale Road and MMTB single line signals.Black and white photograph on Velox paper.On rear in pencil "Colour light signal Wattle Park Route, down end loop line, corner of Riversdale and East Boundary Roads".trams, tramways, riversdale road, wattle park, warragul road, motor cars, hudson super 6, shell fuel, signalling, single line, ray pearson
