Stevenson screens were first introduced in Australia in the 1880s and were widely installed by 1910. The screens have been used to shelter and protect thermometers and other meteorological instruments from rain and direct heat while the holes and double-louvre walls allowed air to flow around them. Sometimes other meteorological instruments were included in the weather stations, so there were different Stevenson Screen sizes. This authentic, original Stevenson screen was previously owned by the Australian Bureau of Meteorology and was used for many years for weather readings at the Cape Otway Light Station in southwest Victoria. The Lighthouse Keepers recorded the readings for minimum and maximum temperatures at 9 a.m. every day from January 1865 until April 1994. The equipment was sheltered in a Stevenson Screen from 1902 until April 15 1994, when the mercury thermometer was replaced by a platinum resistance probe within an Automatic Weather Station (AWS). This Stevenson screen is one of the two screens that then became redundant. The other Stevenson screen was kept to display to visitors. Lightkeepers were no longer required at the Cape Otway Light station either, due to the automated system. The meteorological instruments donated with the screen were used for measuring temperature and humidity. They are mounted on a metal bracket that fits across the screw holes on the screen’s internal frame. The glass-covered Relative Humidity (RH) sensor was made by the renowned precision instrument maker, Rotronic AG of Switzerland, which was founded in 1965. The firm made its first electronic temperature and humidity instrument in 1967. Meteorological records have been collected in Australia from the 1800s. The records were collated, published and used as a basis for weather forecasts. Many sectors, such as maritime and agriculture industries, have relied on these figures for making important decisions. The quality and placement of the meteorological instruments used to measure temperature and humidity are of utmost importance for accuracy. In early colonial times, there were no national standards for meteorological instruments that would allow for accurate figures and comparisons. Once the Bureau of Meteorology was established (around 1908 to 1910) the department installed Stevenson screens throughout Australia, many at lighthouses and light stations, and the measuring instruments were standardised. The Stevenson Screen was named after its inventor, Scottish Civil Engineer Thomas Stevenson (1818-1887) who was also the father of Robert Louis Stevenson, author. Stevenson developed the small thermometer screen around 1867. It had double-louvred walls around the sides and a top of two asbestos sheets with an air space between them and was thickly painted with a white coating that reflected the sun’s rays. This design was modified in 1884 by Edward Mawley of the Royal Meteorological Society. Standards were set for the locations of the screens and instruments, including their distance above ground level and the direction the door faced.Stevenson screens played a significant part in providing a standardised shelter for all meteorological instruments used by the Australian Bureau of Meteorology from about 1910 until 1994. The readings from the instruments gave the meteorological statistics on which weather forecasts throughout Australia were based. This Stevenson screen was used locally at Cape Otway, along the Great Ocean Road in southwest Victoria, so contributed towards our local forecasts and weather warnings.Stevenson screen, original, from the Australian Bureau of Meteorology’s weather station at the Cape Otway Lighthouse. The screen is a white wooden cupboard with a slanted cover raised above the top. The top has ten drilled ventilation holes, and the sides and door are made of downward-slanting double louvres. Two brass hinges join the door to the lower edge of the screen and a metal fitting at the top edge allows for a padlock closure. The screen is supported on four short legs, each with a hole drilled from side to side for fitting to a frame. Inside the screen are two wooden frames fitted with hooks and screws. The floor has three boards; one across the back and one across the front at the same level, and a board wider than the space between these boards is fitted higher, overlapping them slightly. Inside the screen, a pair of electronic instruments with short electric cables is mounted on a metal bracket with drilled holes in it. One of the instruments is a Relative Humidity (RH) probe. It is 26 cm long and is a glass tube with a filter on one end and an electrical connection on the other. It has inscriptions on its label, showing that was made by Rotronic AG, Switzerland. The other instrument is a Resistance Temperature Device (RTD) thermometer. It is 22.5 cm long and has a narrow metal probe joined to a hexagonal metal fitting. A brass plate on the front of the screen has impressed inscriptions. The screen is Serial Number 01/C0032, Catalogue Number 235862.Stamped into brass plate "CAT.

The Victorian Gold Jubilee Exhibition, held at Bendigo from 13 November 1901 to 14 May 1902. The courts were numbered from one, or had titles like “Machinery”, “Agricultural”, “Naval & Military Court” and “Art”. The female visitors to the Exhibition were able to view exhibits deemed suitable for the fairer sex and located within their own “Women’s Court”. There were exhibits such as “Parasols & Umbrellas”, cotton and haberdashery from Manchester and Staffordshire, “Corsets & Embroideries” from Paris. The most valuable exhibits were mining machinery such as Taylor Horsfield’s £850 “Air Compressor & Rock Borer”. “Bohemian Glassware” brought down from Sydney was valued at £600. The profits from this Exhibition were used to fund the sculpture known as the Gold Monument, which still gazes along Pall Mall (from the McCrae Street end). The Exhibition’s Cash Book shows payments, which totalled £1160, were made to then up and coming sculptor C.D.Richardson. Recently a City of Greater Bendigo staff member used both these volumes to write a detailed report about this monument, for Heritage Victoria.Carol Holsworth Collection: Small book Souvenir, 29 pages plus cover; each page. has a photo of the exhibit.

W.B Withers wrote of Sutton: "In the realm of science Ballarat has become of world-wide fame through the inventions by Mr Henry Sutton, a native of the place. His skill and acquirements in electricity, telegraphy, telephony, photography and also in astronomical and microscopal studies have won for him a high position as a practical scientist, and the credit is the greater as he is a self-taught student … Mr Sutton, before he was fourteen years old, had read every book on science to be found in the library of the Ballarat Mechanics' Institute." The Ballarat School of Mines (SMB) was fortunate to have this genius appointed as the lecturer-in-charge of the new Electricity and Magnetism department from 23 April 1883. Although Henry Sutton submitted his resignation to the Council of SMB in October 1884 it was resolved that he be asked to reconsider, and Mr Sutton continued to teach at SMB until the end of 1886. He was a prominent member of the Camera Club, and many of the other SMB clubs. Sutton had an active and fertile brain, and was known for his inventions, especially his work on the telephone, telephane and carbon lamps. Sutton presented a vacuum pump, worked by water jet, for use in SMB Chemistry classes. His report of 1883 states: ‘A telephonic circuit has been laid down between the [SMB] engine-house and workshops, to be used for experimental purposes.’ Henry Sutton spent much thought on artificial flight, and made some interesting experimental studies with flying birds. The storage of electricty also attracted his attention, and, after much work and thought evolved the Sutton Secondary Battery. A paper on this battery was presented to the Royal Society, London, and was afterwards printed in the 'Transactions'. Henry Sutton is listed on the Federation University Honour Roll at https://www.federation.edu.au/curator/honour-roll/honourroll_sutton.shtmlA crude scientific instrument that measures amps, with a timber base and frame. Terminal posts and sliders contacts are positioned on top of the base, with flex attached. Henry Sutton lectured at the Ballarat School of Mines (SMB) in Electricty and Magnestism between 1883 and 1886. In 1883 Sutton reported: ‘…The class has been unfortunately situated, by having to wait for instruments of precision ordered from England, but which have not come to hand. The delay has caused us to start constructing instruments, which it is hoped will bear favourable comparison with those of older date.'ammeter, henry sutton, electrical, inventor, electricity and magnetism, sutton, scientific instruments

A Crookes tube is an early experimental electrical discharge tube, invented by English physicist William Crookes and others around 1869-1875, in which cathode rays, streams of electrons, were discovered. Wilhelm Röntgen discovered X-rays using the Crookes tube in 1895. The term is also used for the first generation, cold cathode X-ray tubes, which evolved from the experimental Crookes tubes and were used until about 1920.(http://en.wikipedia.org/wiki/Crookes_tube)Glass vacuum tube with a metal maltese cross inside. The tube is on a timber stand.scientific instruments, crookes tube, science, maltese cross, scientific objects

The design of this and other similar treadle powered dental engine (or dentist drill) was in common use by dentists from the 1870’s into the 1920's. When electricity became accessible to most communities the electrically powered dental engines began to take over from the treadle power. Over the ages teeth were extracted using picks and scissors and other gouging instruments. Bow drills, hand drills and even a "bur thimble" drill were later used to prepare cavities for filling. Some drills were made bendable by attaching flexible shanks between the metal bur and the handle, giving access to the teeth at the back of the mouth. Other mechanical devices were introduced along the way, such as clockwork drills, but they were hard to handle and inefficient. Over the centuries “dentistry has been performed by priests, monks and other healers. This was followed by barbers; the barber’s chair may well have been the precursor to the dental chair. “(SA Medical Heritage Society Inc.) In 1871 James Morrison patented the first commercially manufactured 'foot treadle dental engine', the first practica dental engine although others had been introduced as early as 1790 (by John Greenwood). Handmade steel burs or drills were introduced for dental handpieces, taking advantage of the significant increase in the speed of the drill. In 1891 the first machine-made steel burs were in use. The treadle drill reduced the time to prepare a cavity from hours to less than ten minutes. In 1876 the Samuel S. White Catalogue of Dentist Instruments listed a 12 ½ inch wheel diameter dental engine, with 14 bright steel parts, for sale at US $55 In today’s market, this is the equivalent to US $1200 approx. The specifications of that dental engine are very similar to the this one in our Flagstaff Hill Maritime Village’s collection. It is interesting to note that workings of a similar treadle dentist drill were used and modified to power a treadle spinning wheel of one of the volunteer spinners at Flagstaff Hill Maritime Village. The foot treadle dental engine was a milestone in dental history. “Historic importance of treadle powered machines; they made use of human power in an optimal way” (Lowtech Magazine “Short history of early pedal powered machines”) The invention of a machine to speed up the process of excavation of a tooth lead to the invention of new burs and drills for the handpieces, improving speed and the surgical process of dentistry. They were the fore-runner of today’s electrically powered dental engines. This treadle-powered dentist drill, or dentist engine, is made of iron and steel and provides power for a mechanical dental hand-piece that would be fitted with a dental tool. The drill has a three footed cast iron base, one foot being longer than the other two. A vertical C shaped frame is joined into the centre of the base, holding an axle that has a driving-wheel (or flywheel) and connecting to a crank. A slender, shoulder height post, made from telescoping pipes, joins into the top of this frame and is height adjusted by a hand tightened screw with a round knob. On the post just above the frame is a short metal, horizontal bar (to hold the hand-piece when it is not in use). A narrow tubular arm is attached to the top of the stand at a right angle and can move up and down. At the end of the arm is a firmly fixed, flexible rubber hose protected for a short distance by a sheath of thin metal. At the end of the hose there is a fitting where the drill’s hand-piece would be attached; a small, silver coloured alligator clip is also at the end. A treadle, or foot pedal, is hinged to the heel to the long foot of the base, and joined at the toe to the crank that turns the driving-wheel. There is a spring under the toe of the treadle. The metal driving-wheel has a wide rim. Touching the inside of the rim are four tubular rings that bulge towards the outside of the driving-wheel, away from the pole, and all meet at the hub of the axle. The axle is bulbous between the inside of the driving-wheel and the frame then passes through the frame and is attached on the other side. The driving-wheel has a groove around which a belt would sit. The belt would also fit around a pulley on the arm, at the top of the post. The pulley is joined to a rod inside the arm and this spins the drill's hand-piece and dental tool holder. The two shorter feet of the base are made from a long metal bar that has been curved outwards, and its centre is bolted to the base of the pole. Under the ends of the curved legs of the base are wedge shaped feet. The driving-wheel is decorated in light coloured paint on both sides, each side having three sets of floral decals evenly spaced around them, and each about a sixth of the wheel's circumference. Similar decoration is along the sides of the frame. The foot pedal has decorative cutout patterns in the centre of the foot and at the toe. On the long foot of the stand is some lettering with a fine, light coloured border around it. The lettering is hard to read, being a dark colour and flaking off. There are also remnants of fine, light coloured flourishes. The foot pedal has lettering of the maker’s trade mark cast into the metal at the ball of the foot. Lettering on the base is peeling and difficult to read. The foot pedal has a trade mark cast into it that looks like a combination of ‘C’ , ‘S’ , ‘A’, ‘R’. flagstaff hill, warrnambool, shipwrecked coast, flagstaff hill maritime museum, maritime museum, shipwreck coast, flagstaff hill maritime village, great ocean road, dentist, teeth, dental drill, dental engine, treadle drill, foot powered drill, treadle engine, orthodontics, dental surgery, james morrison

The design of this and other similar treadle powered dental engine (or dentist drill) was in common use by dentists from the 1870’s into the 1920's. When electricity became accessible to most communities the electrically powered dental engines began to take over from the treadle power. Over the ages teeth were extracted using picks and scissors and other gouging instruments. Bow drills, hand drills and even a "bur thimble" drill were later used to prepare cavities for filling. Some drills were made bendable by attaching flexible shanks between the metal bur and the handle, giving access to the teeth at the back of the mouth. Other mechanical devices were introduced along the way, such as clockwork drills, but they were hard to handle and inefficient. Over the centuries “dentistry has been performed by priests, monks and other healers. This was followed by barbers; the barber’s chair may well have been the precursor to the dental chair. “(SA Medical Heritage Society Inc.) In 1871 James Morrison patented the first commercially manufactured 'foot treadle dental engine', the first practica dental engine although others had been introduced as early as 1790 (by John Greenwood). Handmade steel burs or drills were introduced for dental handpieces, taking advantage of the significant increase in the speed of the drill. In 1891 the first machine-made steel burs were in use. The treadle drill reduced the time to prepare a cavity from hours to less than ten minutes. In 1876 the Samuel S. White Catalogue of Dentist Instruments listed a 12 ½ inch wheel diameter dental engine, with 14 bright steel parts, for sale at US $55 In today’s market, this is the equivalent to US $1200 approx. The specifications of that dental engine are very similar to the this one in our Flagstaff Hill Maritime Village’s collection. It is interesting to note that workings of a similar treadle dentist drill were used and modified to power a treadle spinning wheel of one of the volunteer spinners at Flagstaff Hill Maritime Village. The foot treadle dental engine was a milestone in dental history. “Historic importance of treadle powered machines; they made use of human power in an optimal way” (Lowtech Magazine “Short history of early pedal powered machines”) The invention of a machine to speed up the process of excavation of a tooth lead to the invention of new burs and drills for the handpieces, improving speed and the surgical process of dentistry. They were the fore-runner of today’s electrically powered dental engines. This treadle-powered dentist drill, or dentist engine, is made of iron and steel and provides power for a mechanical dental handpiece that would be fitted with a dental tool. On the foot is painted lettering naming it "The Brentfield" and there is a fine line of light coloured paint creating a border around the name. The paint under the lettering is peeling off. The drill has a Y-shaped, three footed cast iron base, one foot being longer than the other two. A vertical frame is joined into the centre of the base, holding an axle that has a driving-wheel (or flywheel) and connecting to a crank. A slender, shoulder height post, made from adjustable telescoping pipes, joins into the top of this frame. On the post just above the frame is a short metal, horizontal bar (to hold the hand-piece when it is not in use). A narrow tubular arm is attached to the top of the stand at a right angle and can move up, down and around. There is a pulley each side of the joint of the arm and a short way along the arm is fitted a short metal pipe. A little further along the arm a frayed-ended cord hangs down from a hole. At the end of the arm is another pulley and a joint from which hangs a long, thin metal pipe with two pulleys and a fitting on the end. A treadle, or foot pedal, is joined to the long foot of the base, and joined at the toe to the crank that turns the driving-wheel. The metal driving-wheel has a wide rim. Touching the inside of the rim are four tubular rings that bulge towards the outside of the driving-wheel, away from the pole, and all meet at the hub of the axle. The axle fits between the inside of the driving-wheel and the frame then passes through the frame and is attached on the other side. The driving-wheel has a groove around which a belt would sit. The belt would also fit around a pulley on the arm, at the top of the post. The pulley is joined to a rod inside the arm and this spins the drill's hand-piece and dental tool holder. The foot pedal has a cross-hatch pattern on the heel and the ball of the foot has tread lines across it. The end of the toe and the instep areas have cut-out pattern in them.
