Ammeter, Henry Sutton (probably), Ammeter attributed to Henry Sutton, 1883 (estimated)
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 -

Equipment - Scientific Instrument, Crookes Tube
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 -

Equipment - Dentist Drill, Late 19th century
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 -

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 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.

Equipment, Elwell-Powell, Elwell-Parker AC Generator
This AC generator operated for the State Electricity Commission in the Ballarat North Power Station prior to World War Two. James Oddie of Ballarat has an association with Thomas Parker of Elswell-Parker. In early 1887 Oddie arrived in England seeking information on electrical knowledge and its developments. At this time Henry Sutton was teaching Electricity and Magnetism at the Ballarat School of Mines. Oddie stayed in the United Kingdom for around three years and during that time became a close friend of Thomas Parker and his family. The two first met at the first official running of the Blackpool tram, and Oddie was invited to visit Parker at Wolverhampton. Over the years Thomas Parker kept newspaper cuttings (mainly Australian) relating to James Oddie and his work. The following article is a description of the Wolverhampton works by James Oddie, and was collected by Thomas Parker. After the dinner at Blackpool, Mr. Parker visited me, and cordially invited me to see his extensive works at Wolverhampton, an invitation I was not slow to avail myself of. This was the keynote of the best friendship I made in England. I went shortly afterwards and stayed several days, visiting the works daily, as Mr. Parker gave me the run of the whole works. There I ordered the installation of a 60 light dynamo, with a 28 cell storage battery and paraphernalia, now doing duty at the Observatory. I subsequently visited the works frequently, sometimes for a week at a time, and I regard it as the brightest spot in my English constellation. Mr. Parker started his works in 1880, with one man beside himself. He never had a single day’s instruction in electricity in his life; now he daily instructs between 300 and 400 employees, who worship him as a father. He is said to be now the most practical electrical engineer and mechanist in Europe. During one of my visits I took with me an artist, who is painting for me a portrait, 6 feet by 5 feet, of Mr. Parker, surrounded by dynamos, secondary batteries, measuring instruments etc. Electric tram cars are going to be a big thing in England. Parker’s Company Limited, is now, with three other companies, in the hands of the Electric Construction Company, with Mr. Parker as manager of the lot. The whole of the works will be taken to Wolverhampton. Before I left, a tender for £50,000 was accepted for the construction of new works.AC Generator painted read and black on a stand.

... be as high as 10,000 µF. scientific instrument capacitor electrical ...DEFINITION microfarad Posted by: Margaret Rouse WhatIs.com Contributor(s): Kenda, Jack Clements The microfarad (symbolized µF) is a unit of capacitance, equivalent to 0.000001 (10 to the -6th power) farad. The microfarad is a moderate unit of capacitance. In utility alternating-current (AC) and audio-frequency (AF) circuits, capacitors with values on the order of 1 µF or more are common. At radio frequencies (RF), a smaller unit, the picofarad (pF), is often used. This unit is equal to .000000000001 (10^-12) µF. In RF scenarios, capacitances range from about 1 pF to 1,000 pF in tuned circuits, and from about 0.001 µF to 0.1 µF for blocking and bypassing. At audio frequencies (AF), capacitances range from about 0.1 µF to 100 µF. In power-supply filters, capacitances can be as high as 10,000 µF. Capacitor, 1/3 M.F.D.
