The water pump pressure gauges were used by the Wodonga Waterworks Trust and Sewerage Authority, which were established in 1897, and had the responsibility for providing Wodonga's drinking water and managing the wastewater. In 1923 a Wodonga Waterworks Trust referendum to provide funding for new infrastructure to supply more water of better quality to Wodonga was passed. This included building the Wodonga Water Tower and it was completed in 1924. It supplied water to Wodonga until 1959, when it was drained and decommissioned after the No 1 Basin on Huon Hill was completed in 1958. In 1983 the Wodonga Waterworks Trust and the Wodonga Sewerage Authority became part of the Wodonga Council. By 1989 a filtration plant at Huon Hill was completed, which provided filtered water of improved quality to Wodonga, in accordance with the World Health Organisation’s guidelines. In 1994 the Kiewa Murray Region Water Authority took over the Wodonga Council’s water and wastewater operations, and then in 1999 the Kiewa Murray Region Water Authority combined with the Ovens Region Water Authority and became the North East Region Water Authority or NERWA. NERWA then became known as North East Water.The water pump pressure gauges have local significance due to their use by the Wodonga Waterworks Trust and Sewerage Authority, and donation from the North East Region Water Authority. They also have wider historical significance as examples of the equipment used in the management of water in Victoria and Australia.Five metal and glass water pump pressure gauges, including one with a U-shaped pipe and lever attached.

A steam boiler like this late 18th century boiler, is often called a colonial boiler. Steam boilers were used in factories throughout Australia, mounted over similar designs of brick furnaces. This heat from the fire travels through the tubes in this fire tube boiler and the water heats as it circulates around them. Another kind of boiler is a water tube boiler, in which the water is inside the tubes and the heat of the combustion surrounds the tubes. The boiler in our collection burned wood as fuel but others of this design could also burn coal, coke, gas and liquid fuels. The boiler was made by T & F Johnson, boilermakers. In 1922 their factory was located at Coventry Street, South Melbourne. They were still advertising their 'Colonial, multi, vertical boilers, all sizes' at the same address in 1934. The connected pressure gauge, made in London by Dewrance, measures 0 to 400 pounds per square inch. John Dewrance is renowned as a pioneer of the steam locomotive in the early 19th century. He founded John Dewrance & Co. in South London in 1844. His son Sir John Dewrance took over in 1879. In 1939 the company became a subsidiary of Babcock & Wilcox, and was eventually owned by Emerson. How the boiler works: - A boiler is about two-thirds filled with water and heat is applied, in this case in the form of burning wood. The heat is transferred through the metal of the boiler to the water. When the water boils the steam rises to the top, and as it escapes from the boiler the steam pressure builds up in the steam space to later be released to do work; drive machinery such as ship and train engines, turbines, presses, wheels, and driving belts to operate looms and saws. The heat associated with the boiler can be used for preserving food, sterilising, factory manufacturing processes, and steaming wood for shipbuilding. Every boiler has several components fitted for safe operation: - - Safety valves - Gauge glass - Pressure gauge - Main steam stop valve - Water check valve - Blowdown valve - Manhole doorThe boiler is a significant item that gives us a snapshot of early Melbourne's industrial history. It is an example of the technological advancement during the Industrial Revolution where steam-driven machinery and motors could perform tasks more efficiently than manual labour. The makers were one of many boilermaker businesses in Melbourne during the early late-19th andearly 20th centuries. The maritime trade and skills of boilermaking are still learned and applied today. The Dewrance steam pressure gauge connected to the boiler was made by the London firms foundered by John Dewrance. He was renowned for developing the steam locomotive in the early 19th century.Boiler; a horizontal cylindrical underfired steam boiler. It is a multi-tubular design and is timber plank-clad, with brass fittings and pressure gauges. The boiler has an iron door at one end with a metal chimney above it. It is installed over a brick-enclosed solid fuel furnace. Two large, wood-mounted pressure gauges are connected to the boiler and have inscriptions. An inscription is on a red, cast iron plaque above the boiler door. The boiler's maker is T & F Johnson, South Melbourne.

Victorian Institute of Occupational Safety and Health (VIOSH) Australia is the Asia-Pacific centre for teaching and research in occupational health and safety (OHS) and is known as one of Australia's leaders on the field. VIOSH has a global reputation for its innovative approach within the field of OHS management. VIOSH had its first intake of students in 1979. At that time the Institution was known as the Ballarat College of Advanced Education. In 1990 it became known as Ballarat University College, then in 1994 as University of Ballarat. It was 2014 that it became Federation University. VIOSH Australia students are safety managers, senior advisors and experienced OHS professionals. They come from all over Australia and industry. Students are taught active research and enquiry; rather than textbook learning and a one-size fits all approach. VIOSH accepts people into the Graduate Diploma of Occupational Hazard Management who have no undergraduate degree - on the basis of extensive work experience and knowledge.

This compressor was part of the E.G. Ward Collection. It is connected to the diving suit and boots also in our collection. Siebe Gorman & Company Ltd was a British company that developed diving equipment and breathing equipment and worked on commercial diving and marine salvage projects. The company advertised itself as 'Submarine Engineers'. It was founded by Augustus Siebe, a German-born British engineer chiefly known for his contributions to diving equipment. Siebe Gorman traded as an engineering firm for over 180 years from 1819 to 1999. The early success of the business was due to its founder, the Prussian immigrant Christian 'Augustus' Siebe (1788-1872). For business reasons, he applied for and was granted British citizenship in 1856. He was a gifted engineer who was able to translate theoretical problems into practical, working products. During the industrial Victorian period, the business traded as 'A. Siebe' at 145 High Street Holborn London, but in 1828 new premises were acquired at 5 Denmark Street, Soho. The family firm produced a wide range of manufactured goods including paper-making machinery, measuring machinery, water-pumps, refrigeration equipment and diving apparatus. Augustus Siebe specialised in submarine engineering early on and the company gained a reputation for the manufacture of safe, reliable diving apparatus. Augustus Siebe is best remembered for the development and manufacture of the ‘closed’ Diving Dress based on the ideas of Charles and John Deane, George Edwards and Charles Pasley. Apart from some small modifications to valves and diver communications, the basic 12 bolt ‘closed’ diving dress remained relatively unchanged after the 1870s. Later company successes were also based on innovation, with new products that could be successfully developed and manufactured to high standards. This was largely attributed to the inventive nature, foresight, engineering and entrepreneurial skills of Robert Henry Davis (1870-1965). In 1882, RH Davis joined the company of 'Siebe & Gorman' as a young 11-year-old office boy and he was to remain with the company until he died in 1965. Augustus Siebe retired in 1869 and handed over the company to a new partnership of Henry H. Siebe (1830-1885) and William A. O'Gorman (1834-1904). The new firm traded as 'Siebe & Gorman' (1870-1879) from premises in and around Mason Street, Westminster Bridge Road, Lambeth, London. The two partners soon recognised the potential of R.H. Davis and in 1894, aged 24, he became General Manager of Siebe & Gorman. Davis increasingly ran the company until the surviving partner (W.A. Gorman) died in 1904. The firm was disposed of to the Vickers (armaments) family and a new company 'Siebe Gorman & Co. Ltd.' (1905-1998) was formed. Under the chairmanship of Albert Vickers, R.H. Davis was kept on as Managing Director, and the company forged ahead. However, after WW1, the Great Depression caused manufacturing output and share prices to slump. In 1924 Robert Davis made a deal with the Vickers Board and acquired control of the company through majority shares. Under his leadership, the Siebe Gorman Company flourished and within time, four of his sons also joined the firm. The company gained a worldwide reputation for the manufacture of diving apparatus, decompression and observation chambers, and safety breathing apparatus of all types for use on the land, in the air and under the sea (including mine rescue, tunneling, aircraft, diving, submarine escape and in other hazardous environments). Close research and development links with the MOD (especially the Admiralty), also provided a lucrative outlet for the company products. In 1932, Robert Davis was knighted by King George V, principally for his invention of the ‘Davis Submerged Escape Apparatus’ (D.S.E.A.). Siebe Gorman essentially remained a family firm from the beginning (under A Siebe) until it became a public company for the first time in 1952. However, following WW2, British manufacturing stagnated through stifled investment and post-war austerity, and there was little innovation. Siebe Gorman fortunes began to decline as an ageing Sir Robert Davis failed to invest, or change the company business and management practices. In 1959, Siebe Gorman was acquired by the “Fairy Group” and the ailing Sir Robert was made Life President. Consequently, nothing changed and the slow decline continued until Sir Robert's death in March 1965. Around 1960, Siebe Gorman acquired the diving apparatus manufacturer C E Heinke, and for a brief period, it manufactured some diving equipment under the combined name of Siebe Heinke. Around 1964, Mr. E. 'Barry' Stephens was appointed as the new Managing Director to modernise Siebe Gorman. Changes were made, including a move to a new factory in Wales in 1975. The new company concentrated on fire fighting breathing apparatus and escape equipment, and the move coincided with the loss of many of the older, traditional craft skills. Between 1985 and 1998, Siebe expanded through acquisitions, and several other companies were acquired. The Siebe Gorman (diving apparatus) company has therefore traded as A. Siebe (1819-1870); Siebe & Gorman (1870-1879); Siebe Gorman & Co (1880-1904); Siebe Gorman & Co. Ltd (1905-1998).The compressor is a very significant item as it gives a snapshot into marine history and the development of diving equipment generally especially that used for salvage operations before and during WW2. Siebe & Gorman the company that made the equipment was a leading inventor, developer and innovator of marine equipment with its early helmets and other items eagerly sought after today for collections around the world. The items in the Flagstaff Hill collection give us an insight as to how divers operated and the dangers they faced doing a very necessary and dangerous job during the early days of marine exploration.A single cylinder divers' pump by Siebe Gorman & Co Ltd, London, eccentric hand cranked in brass mounted mahogany case with instructions to the underside of the lid, brass covered pressure gauge and air outlet, brass makers plaque to the front, water inlet and outlet to the rear, green painted lifting rings.

The Loch Ard got its name from "Loch Ard" a loch that lies to the west of Aberfoyle, and the east of Loch Lomond. It means "high lake" in Scottish Gaelic. The vessel belonged to the famous Loch Line which sailed many vessels from England to Australia. The Loch Ard was built in Glasgow by Barclay, Curle & Co. in 1873, the vessel was a three-masted square-rigged iron sailing ship that measured 79.87 meters in length, 11.58 m in width, and 7 m in depth with a gross tonnage of 1693 tons with a mainmast that measured a massive 45.7 m in height. Loch Ard made three trips to Australia and one trip to Calcutta before its fateful voyage. Loch Ard left England on March 2, 1878, under the command of 29-year-old Captain Gibbs, who was newly married. The ship was bound for Melbourne with a crew of 37, plus 17 passengers. The general cargo reflected the affluence of Melbourne at the time. Onboard were straw hats, umbrellas, perfumes, clay pipes, pianos, clocks, confectionery, linen, and candles, as well as a heavier load of railway irons, cement, lead, and copper. There were other items included that were intended for display in the Melbourne International Exhibition of 1880. The voyage to Port Phillip was long but uneventful. Then at 3 am on June 1, 1878, Captain Gibbs was expecting to see land. But the Loch Ard was running into a fog which greatly reduced visibility. Captain Gibbs was becoming anxious as there was no sign of land or the Cape Otway lighthouse. At 4 am the fog lifted and a lookout aloft announced that he could see breakers. The sheer cliffs of Victoria's west coast came into view, and Captain Gibbs realised that the ship was much closer to them than expected. He ordered as much sail to be set as time would permit and then attempted to steer the vessel out to sea. On coming head-on into the wind, the ship lost momentum, the sails fell limp and Loch Ard's bow swung back towards land. Gibbs then ordered the anchors to be released in an attempt to hold their position. The anchors sank some 50 fathoms - but did not hold. By this time the ship was among the breakers and the tall cliffs of Mutton Bird Island rose behind. Just half a mile from the coast, the ship's bow was suddenly pulled around by the anchor. The captain tried to tack out to sea, but the ship struck a reef at the base of Mutton Bird Island, near Port Campbell. Waves subsequently broke over the ship and the top deck became loosened from the hull. The masts and rigging came crashing down knocking passengers and crew overboard. When a lifeboat was finally launched, it crashed into the side of Loch Ard and capsized. Tom Pearce, who had launched the boat, managed to cling to its overturned hull and shelter beneath it. He drifted out to sea and then on the flood tide came into what is now known as Lochard Gorge. He swam to shore, bruised and dazed, and found a cave in which to shelter. Some of the crew stayed below deck to shelter from the falling rigging but drowned when the ship slipped off the reef into deeper water. Eva Carmichael a passenger had raced onto the deck to find out what was happening only to be confronted by towering cliffs looming above the stricken ship. In all the chaos, Captain Gibbs grabbed Eva and said, "If you are saved Eva, let my dear wife know that I died like a sailor". That was the last Eva Carmichael saw of the captain. She was swept off the ship by a huge wave. Eva saw Tom Pearce on a small rocky beach and yelled to attract his attention. He dived in and swam to the exhausted woman and dragged her to shore. He took her to the cave and broke the open case of brandy that had washed up on the beach. He opened a bottle to revive the unconscious woman. A few hours later Tom scaled a cliff in search of help. He followed hoof prints and came by chance upon two men from nearby Glenample Station three and a half miles away. In a complete state of exhaustion, he told the men of the tragedy. Tom then returned to the gorge while the two men rode back to the station to get help. By the time they reached Loch Ard Gorge, it was cold and dark. The two shipwreck survivors were taken to Glenample Station to recover. Eva stayed at the station for six weeks before returning to Ireland by steamship. In Melbourne, Tom Pearce received a hero's welcome. He was presented with the first gold medal of the Royal Humane Society of Victoria and a £1000 cheque from the Victorian Government. Concerts were performed to honour the young man's bravery and to raise money for those who lost families in the disaster. Of the 54 crew members and passengers on board, only two survived: the apprentice, Tom Pearce, and the young woman passenger, Eva Carmichael, who lost her family in the tragedy. Ten days after the Lochard tragedy, salvage rights to the wreck were sold at auction for £2,120. Cargo valued at £3,000 was salvaged and placed on the beach, but most washed back into the sea when another storm developed. The wreck of Lochard still lies at the base of Mutton Bird Island. Much of the cargo has now been salvaged and some items were washed up into Lochard Gorge. Cargo and artifacts have also been illegally salvaged over many years before protective legislation was introduced in March 1982. One of the most unlikely pieces of cargo to have survived the shipwreck was a Minton majolica peacock- one of only nine in the world. The peacock was destined for the Melbourne 1880 International Exhibition. It had been well packed, which gave it adequate protection during the violent storm. Today the Minton peacock can be seen at the Flagstaff Hill Maritime Museum in Warrnambool. From Australia's most dramatic shipwreck it has now become Australia's most valuable shipwreck artifact and is one of very few 'objects' on the Victorian State Heritage Register.The shipwreck of the Loch Ard is of significance for Victoria and is registered on the Victorian Heritage Register ( S 417). Flagstaff Hill has a varied collection of artifacts from Loch Ard and its collection is significant for being one of the largest accumulation of artifacts from this notable Victorian shipwreck of which the subject items are a small part. The collection's objects give us a snapshot of how we can interpret the story of this tragic event. The collection is also archaeologically significant as it represents aspects of Victoria's shipping history that allows us to interpret Victoria's social and historical themes of the time.
