Opera Glasses came into existence as a result of a long line of inventions, and further improvements upon those inventions. The process started in the year 1608 when a Dutch optician by the name of Hans Lipperhey developed the first pair of binoculars with a magnification capability of X3. Less than a year later, a well-known inventor and philosopher by the name of Galileo developed what became known as the Galilean telescope. Advertisements were first found for opera glasses and theatre binoculars in London as early as 1730 in the form of a long collapsible telescope. The "Opera Glass" as it was referred to; was often covered in enamel, gems, ivory, or other art and paintings. For almost 100 years opera glasses existed merely as telescopes. In Vienna, in 1823 the first binocular opera glasses and theatre binoculars began to appear. They were two simple Galilean telescopes with a bridge in the centre, each telescope focused independently from the other by extending or shortening the telescope until the desired focus was achieved, which was useful, yet very cumbersome. Two years later in Paris, Pierre Lemiere improved on this design and created a centre focus wheel. This allowed the focusing of both telescopes together. After this development, opera glasses and theatre binoculars grew in popularity because of the superior view they facilitated in opera and theatre houses. The beautiful design of the glasses themselves also added appeal to the opera-going crowd. By the 1850's opera glasses and theatre, glasses had become a must-have fashion accessory for all opera and theatergoers.Not very significant as not associated with a historic event or person and made during the first half of the 20th Century and many are still available and easily sourced.Vintage Pair of Opera Glasses, with cow bone barrels and eyepieces, both barrel pieces have split in them, both metal end barrels each have a minor dent, optics are pretty clear no mould although have very minor dust spots inside, they look like they were gilded at some point but most of this has rubbed off glasses have a black leather case with blue lining.

The nautical compass is used for determining directions, using a free moving magnetised needle, indicating north and south. This is a medium sized compass and was suitable for mounting in a fixed brass binnacle or a portable wooden box. The compass fluid was typically lamp oil, or a mixture of alcohol and water. This compass, based on its pattern, was probably manufactured around the 1930s. The compass’s maker, Bergen Nautik, was a 20th Century compass manufacturer, making compasses from the 1900s but no longer in business.The factory was located in Hordaland County, Bergen, on the west coast of Norway. This compass is not a very significant marine item as it was made in the 20th century. Examples of the same compass that have been salvaged can be purchased today mounted either in a wooden box or a brass pedestal.Compass; marine or ship's compass, brass, gimbal mounting, in blue metal casing.

The flywheel possibly belongs to a Walker's Cherub Mark III Ship-log taffrail, how the flywheel operates is a metal loop of the recording log would have been connected to the flywheel, so you could see if it was spinning properly. After the flywheel, is the rotor that was towed behind the ship and the revolutions of the rotor would register on the indicator, thus measuring the distance the vessel had travelled. Thomas Ferdinand Walker (1837–1921) first patented the Cherub log in 1878. It was one of the first logs in which the recorder was placed onboard a ship rather than being incorporated as part of the rotor. The Cherub Mark III series was produced from 1930 it came in two versions a thousand-mile which is quite rare and a five hundred-mile version.This ship log flywheel was invented and made by a significant marine instrument maker and innovator of machinery Thomas Walker. It demonstrates the huge leap taken to improve navigational accuracy at sea with an instrument that was in use for decades to measure the distance travelled at sea updated versions are in use today by mariners.Log Governor (or Fly-wheel) from a Ships Taffrail Log, metal wheel with 6 spokes, hub has rope attached for connecting to ships log.

The phonograph is a mechanical device for the recording and reproduction of sound and originally used a tinfoil sheet wrapped around a rotating cylinder to produce the sound. It was invented by Thomas Edison of U.S.A. in 1877 and was the model for all phonographs or gramophones made and developed throughout the 20th century. This machine is of particular interest to the Warrnambool and District Historical Society as it is an Edison phonograph and an earlier model of this phonograph was used in Warrnambool late in the 19th century to make an important recording. In 1896 Thomas Rome, an employee in a Warrnambool boot and shoe shop, purchased an Edison phonograph that could both play and record sounds. At the Warrnambool Industrial and Art Exhibition of 1896-7 visitors to the Exhibition paid a fee to listen to music on this phonograph. But Rome also recorded some local Warrnambool people singing and speaking and these recordings survive today. They are regarded as the oldest surviving recordings made in Australia. Thomas Rome later became a shoe shop proprietor in Warrnambool and was a well-known person in the town/city for a great number of years. This is an Edison Gem Phonograph. It has a black-painted wooden base, now detached from the main mechanism. The phonograph is made of metal which is now heavily rusted. It has a cylindrical turntable for playing the Edison cylindrical records and a handle with a wooden knob. The turning mechanism and belt are now broken. The name of the manufacturer and details of the patents are on a metal plate attached to the side of the phonograph. The amplifier mechanism at the top of the machine is missing. The cover of the machine is made of wood and has a wooden handle attached with a piece of metal and two metal screws. There are also two metal screws on the side of the cover. The cover has a slot on the side to allow the turning handle to be accommodated outside of the cover. The cover is much stained and spotted. ‘Edison Gem Phonograph’ thomas edison, history of sound recordings, thomas rome (warrnambool)

This Anaesthetic Mask 'Schimmelbusch' mask was used to deliver chloroform or ether as an anaesthetic. When this mask was in use most doctors would have delivered the anaesthetic themselves. During the 1940s and 1950s, some nurses may have played an active role in the delivery of anaesthetics, particularly in remote areas and during wartime or doctor shortages. This medical / hospital equipment was the latest available in the 1950s when the Tawonga District General Hospital was built specifically for the increase in population due to the Kiewa Hydro Scheme.Historical: Shows the development of scientific hospital equipment. Provenance: Used in the Tawonga District General Hospital which was remote and therefore required good equipment.

This grain scale tester was used to work out the percentage weight of a sack of grain after the grain husk, dust and dirt were removed, thereby allowing for the calculation of the true value of the sack. The parts were attached to the box via the screw on top of the box and the cleaned grain went into the funnel to measure a fixed grain amount, before being released from the bottom of the funnel into the barrel which was then hung on the end of the scale. The weight was then slid down the graduated ruler until the scale balanced. Grain scale testers would have been used in farming in the Western District in the past and similar objects may still be in use. This grain scale tester is retained as a good example of an agricultural item from the past.This is a grain tester scale in a wooden box. .1 The wooden box has two metal hinges and wooden inserts inside with blue felt on the tops of the inserts.

The Davey Paxman Experimental Steam Engine was purchased as the result of a bequest from Thomas Bath. The 'substantial sum' was used to build an Engineering Laboratory. The Ballarat School of Mines Council minutes of 08 November 1901 record: - Plans for [the] proposed building were submitted ... and ... it was resolved that a temporary building for an Engineering Laboratory be put up.' This laboratory, as an existing building, is first mentioned in the Ballarat School of Mines President's Annual Report of 1901, presented on 28 February 1902, reporting 'the erection of a building 67ft long by 33 ft wide' This report also lists all the equipment that would be accommodated in the Engineering Laboratory, including the experimental steam engine and boiler. The experimental Davey-Paxman steam engine arrived in Ballarat towards the end of 1902. The Engineering Laboratory was opened on 14 August 1903 by His Excellency Sir Sydenham Clarke. This engineering laboratory remained in use till about 1945. By 1944 preparations were under way at the Ballarat School of Mines to expand existing facilities, to be ready for the influx of returned soldiers. A new Heat Engines laboratory was built, this time of brick construction, replacing the previous corrugated-iron shed. In the early stages the steam engine was used to drive an overhead transmission shaft for machinery in the adjacent workshop. Later the steam engine was moved to a space that became the Heat Thermodynamics Laboratory. At the end of 1969 the engine was relocated to the Thermodynamics Laboratory at the then Ballarat Institute of Advanced Education (BIAE) Mt Helen Campus. It was donated to Sovereign Hill in 2006. According to the research of Rohan Lamb in 2001 around five experimental steam engines were made by Davey Paxman, and three of these had similar configuration to the Ballarat School of Mines Steam Engine, however, each of these was also unique with different valve arrangements. The list, which was on a scrap of paper in a folio held in the Essex Archives, confirmed that one was sent to India. The Ballarat steam engine can be dated to late 1901 to early 1902. Zig Plavina was responsible for moving the steam engine to Mount Helen, and worked on it as a technician for many years. He observed the following: * The condenser is driven by the low pressure engine. * The following arrangements are possible: i) the high pressure engine alone, exhausting to atmosphere. Condenser not used, crankshaft flanges not coupled. ii) crankshafts coupled, mains pressure (120 psi) steam supplied to high pressure engine, partially expanded steam delivered to low pressure engine (Tandem operation). Choice available re exhaust steam: either to the condenser or to atmosphere. iii) crankshafts not coupled, reduced pressure steam supplied to low pressure engine. Exhaust steam - either to the condenser or to atmosphere. * Valve arrangement - a choice of Pickering cut-off or throttle governor. On low pressure engine - throttle governor only.Black and white photograph of the Davey Paxman Experimental Steam Engine.
