Steam Engine - Tangye single cylinder vertical, Circa 1920
... Steam Engine - Tangye single cylinder vertical ...vertical steam engine... in major factories, small vertical steam engines like this were...single cylinder vertical Steam Engine made of Cast Iron... vertical steam engines like this were the workhorses of industries ...Used by the Malvern city council until 1969 to drive a rock crushing plant. While large horizontal steam engines predominated in major factories, small vertical steam engines like this were the workhorses of industries that had modest power requirements. This reliable little engine, made by leading UK manufacturer Tangye Bros of Birmingham Steam engines had the advantage that any fuel could be used to fire their boilers, but they were less convenient and efficient than internal combustion engines, required operators with higher skill levels, and had lower power to weight ratios. Tangye Limited was founded in 1857 in Birmingham by businessman Richard Tangye (1833-1906) and his mechanic brothers James and Joseph; brothers Edward and George joined them later. Richard was born near Redruth in Cornwall and educated at the Friends School at Sidcot, Somerset, where he became a pupil-teacher. From there he moved to Birmingham to work as a clerk for an engineering firm. In 1856 he started a hardware factor and commission agent business in Birmingham whose customers were mainly Cornish mine-owners in the Redruth district. From 1858 Tangyes concentrated on the manufacture of machinery and secured the sole right to manufacture Weston's differential pulley block (object 2003/45/1). They established their Cornwall Works in the Birmingham suburb of Smethwick in 1864 and soon developed a huge range of products. It was stated that 'there are perhaps no other works in the kingdom so largely employed upon so great a variety of specialities as the Cornwall Works of Messrs Tangye Bros.' The Tangyes attracted creative people to work for them. They wrote: 'We are in a position to offer unusual facilities to Inventors for carrying out their patents.'

... Steam engine boiler; vertical cylindrical coal-fired boiler... boiler "1948 D/430" Steam engine boiler; vertical cylindrical ...This little steam boiler has been beautifully built. It could have been used to drive an engine in a small workshop, a boat or launch, or even farming equipment. It is an example of the steam technology and mechanisation of the 19th century. William Cook introduced steam heating in England in the 18th century. Steam combined with pressure was used for powering transport, such as steam engines for trains, and manufacturing, such as steam engines driving manufacturing machines. Steam boilers are still used today as an energy-efficient means of power.This steam boiler would have been suitable to drive a small engine, possibly that of a small boat. Coal was added to the firebox for fuel to heat water in the boiler. It is an example of the power used to drive machinery and equipment in the mid-to-late 19th century. Steam boilers like this one have played a part in the evolution of steam power. Steam engine boiler; vertical cylindrical coal-fired boiler with a black firebox at its base and a dome top. The cylinder's sides and top have brass fittings, inlet and outlet taps. A round opening near the base is covered by an adjustable metal plate that controls the boiler's temperature. The front door of the firebox has two hinges at the base and when the side clips are opened. A shiny brass collar tops the tall chimney. Oak wood planks around the sides of the boiler, and held in place by brass bands with nut and screw fixtures. The boiler stands on a metal and wood frame with a looped handle at the back.

Equipment - Ships' Telegraph section, Milne Brothers, Copper and Brass Works, Early-to mid-20th century
This Engine Room section of a ship's telegraph system was part of the equipment of the Ports and Harbour ship the SS Rip. The vessel serviced and maintained the lights and buoys at Port Phillip Bay and Queenscliffe. The SS Rip was possibly the former gunboat "Albert". The ship’s communication system that was used from the late 19th century to early-to-mid-20th-century is called an Engine Order Telegraph (E.O.T.) or ship’s telegraph. The system has two parts, the Bridge Section and the Engine Room Section. The Bridge Section is usually mounted on top of a pedestal, and the Engine Room Section is often attached to a vertical surface. The standard commands printed or stamped onto the dial are the directions of AHEAD and ASTERN, and the speeds of STOP, FULL, EASY, STD. BY. and FIN. ENG. The ship’s pilot on the Bridge of a vessel sends his Orders for speed and direction to the to the Engine Room with the E.O.T. He moves the lever or levers, depending on the number of engines the ship has, to change the indicator on the Bridge Section’s dial to point in the new direction and speed of travel. This change causes the Orders to be duplicated on the Engine Room Section’s dial and a bell to signal the change simultaneously. The engineer then adjusts the ship’s engines and steering equipment to follow the pilot’s Order. The manufacturer, Mulne Bros., was a copper and brass works at 166 Sussex Street Sydney, in December 1892, and previously from 1870 at 128 to 130 Sussex Street. The company made and sold a wide range of equipment including machinery and gauges for the Railways.The Engine Room section is significant for being part of the communications system on the ship SS Rip, owned by Melbourne's Ports & Harbours department and used to service and maintain the navigation signals of Port Phillip Bay and at Queenscliffe in the mid-20th century. The dial is an example of marine equipment made in Australia and used for the safety of Victorian vessels. It is also significant for being made by an early Australian manufacturer, Milne Brothers of Sydney.Engine Room Section of a ship’s telegraph or Engine Order Telegraph (E.O.T.).

Engine Dynamometer, c.1890’s
The steam engine indicator, or dynamometer, is an instrument used on a steam engine (such as that of a vessel or train) to measure and record the change in the pressures of the engine’s cylinders during their operating cycle. The engineer would use it to identify problems or defects such as bad valve settings or constricted steam pipes. It could indicate the difference in efficiency caused by adjustments made to the engine, being able to instantly measure the variation of pressure from the engine stroke at any given time. This force of power would be registered by a pencil, fitted to the adjustable arm, which would trace a line on paper wound around the cylinder. The recorded information could be used in conjunction with mathematical tables. This particular instrument was made by T.S. Mc Innes, one of the better manufacturers of engine indicators. Mc Innes engine indicators were still being used in the mid 1900’s. This specific instrument was used by Mark Forsythe of North Berwial, Scotland and late of Ararat, Victoria when he was chief engineer on the “SS Talawena” in 1892. The Port of Warrnambool, in Victoria, harboured steam ships that carried both passengers and cargo along the south west coast in the late 1800’s and into the 1900’s. The engineer of a steam ship was responsible for reaching and maintaining the optimum level of steam energy to serve the locomotion and efficiency of the steam ship. The engineer would use a steam engine indicator to measure and record information to achieve this purpose. Engine Dynamometer or Steam Engine Indicator in square, fitted oak case. This brass instrument is used to measure and record steam pressure for setting up and adjusting valves on a steam engine. It has an oscillating recording drum with vertical, silver clip attached for holding paper in place around the drum. The drum oscillates left to right. There is a pulley attached to a length of cord, which is attached to the drum. Beside the drum is a fine metal arm, vertically adjustable, small hole in the end to hold a pencil. Inscription stamped into bracket of the arm. The engine indicator is mounted on a hinged side of the case that swings out ready for use. Attached chains prevent the side from opening past vertical. There is storage for other accessories and an empty compartment in the base (where a scale or ruler may have been located). The case has a collapsible wooden handle, brass hinges and two brass, hook-shaped catches. There is a code stamped inside the lid. It contains a brass, ‘T’ shaped steam-cock (or stop cock) with two open ends made of metal pipe with different sized threads. (Turning the handle on top opens and closes the space in the pipe and would close off the flow of steam from one end to the other.) Also inside the case are three different spiral springs, each with a threaded nut on the end that has a threaded hole inside it. Used by Mr Mark Forsythe when chief engineer on the SS Talawena in 1892 “T.S. MC INNES PATENT” and “522 _ _” (last 2 digits are unreadable) pressed into the arm of the brass indicator. “[ ] X ’ stamped inside the lid of the case.

Card Holder, c. 1854 - 1957
This wooden cardholder has been made from the wood of the screw steamer S.S. Edina, most probably after she was broken up in 1957, but could have been made after one of several renovations during her lifetime. The slotted design of the cardholder allows a card to stand vertically and the base is made wider to stableise the holder. It could be used for holding items such as place cards, menus, table numbers. ABOUT THE S S EDINA The three masted iron screw steamer SS Edina was built in Glasgow, Scotland, in 1854 by Barclay and Curle. She was adorned with the figurehead of ‘fair maid of Judea’. The many years of service made SS Edina famous worldwide as the longest serving screw steamer. (The term screw steamer comes from being driven by a single propeller, sometimes called a screw, driven by a steam engine.) SS Edina’s interesting history includes English Chanel runs, serving in the Crimean Ware carrying ammunition, horses and stores to the Black Sea, and further service in the American Civil War and later, serving in the western district of Victoria as well as in Queensland and carried gold, currency and gold prospectors Australia to New Zealand. SS Edina had the privilege of being an escort vessel to H.R.H. the Duke of Edinburgh during his visit to Australia in 1867. In March 1863 SS Edina arrived in Port Phillip Bay, Melbourne, and was bought by Stephen Henty, of Portland fame, to work the cargo and passenger run from Melbourne – Warrnambool – Port Fairy - Portland. After a short time of working the run from Australia to New Zealand, with passengers and cargo that included gold and currency, she returned to her Melbourne - Warrnambool – Port Fairy run, with cargo including bales of wool produced in the western district of Victoria. The Warrnambool Steam Packet Company purchased SS Edina in 1867; she was now commanded by Captain John Thompson and Chief Engineer John Davies. She survived several mishaps at sea, had a complete service and overhaul, and several changes of commanders. In 1870 SS Edina was in Lady Bay, Warrnambool, when a gale sprung up and caused a collision with the iron screw steamer SS Dandenong. SS Edina’s figurehead was broken into pieces and it was not ever replaced. SS Edina was re-fitted in 1870 than was used as a coastal trader in Queensland for a period. She was then brought to Melbourne to carry cargo and passengers between Melbourne and Geelong and performed this service 1880-1938. During this time (1917) she was again refitted with a new mast, funnel, bridge and promenade deck, altering her appearance. In 1938, after more collisions, SS Edina was taken out of service. However she was later renamed Dinah and used as a ‘lighter’ (a vessel without engine or superstructure) to be towed and carry wool and general cargo between Melbourne and Geelong. In 1957, after 104 years, the SS Edina was broken up at Footscray, Melbourne. Remains of SS Edina’s hull can be found in the Maribyrnong River, Port Phillip Bay.

The SS Edina is heritage listed on the Victorian Heritage Database VHR S199. She had endeared herself to the people of Port Phillip Bay as a passenger ferry, part of their history and culture. She played a significant role in the Crimean War, the American Civil War and the gold rush in New Zealand. She also served western Victoria for many years in her cargo and passenger runs. The SS Edina is famous for being the longest serving screw steamer in the world. After spending her first nine years overseas she arrived in Melbourne and her work included running the essential service of transporting cargo and passengers between Melbourne and the western Victoria ports of Warrnambool, Port Fairy and Portland. The SS Edina was purchased in the late 1860’s by local Warrnambool business, the Warrnambool Steam Packet Co. and continued trading from there as part of the local business community. The SS Edina’s original ‘fair maid of Judea’ figurehead was broken to pieces in a collision with another vessel (the SS Dandenong) in a gale off Warrnambool, Victoria, in 1870.

Domestic object - Chest of Drawers, British Imperial Oil Company Ltd, 1905-1927
This early 20th-century chest of drawers is unique. It was made from recycled timber kerosene boxes and metal tins. The case was made in South Australia between 1905 and 1927 by the British Imperial Oil Company Ltd, which was the first business to import bulk petroleum products into Australia. Before this, ships carried crates of kerosene as cargo. Items salvaged from the 1880 wreck of the vessel Eric the Red included kerosene boxes. Kerosene replaced plant and animal-based fuel, such as whale oil, for lighting in homes and for the lamps in lighthouses and on marine vessels. It was also used for cooking and heating and as engine fuel. The last kerosene-fueled lighthouse lamp was transferred to solar power in 1985. The chest of drawers is one-of-a-kind. The original uses for the components of the chest of drawers, the wooden box and metal tins were for containing and transporting kerosene. Kerosene was used from the late 19th century for fuel in lamps, heating, and cooling. Previously whale oil was used for the lamps in lighthouses. The company providing the kerosene was the first to import it into Australia in bulk quantities. The set of drawers is one of the many ways that inventive Australians were able to repurpose materials.Chest of drawers; wooden frame and rails, metal drawers with vertical metal handles. The frame has been constructed from the wooden panels of a vintage oil and kerosene box. The three drawers have been created from empty kerosene cans that were cut in half from top to bottom, some with the round opening closed over. Inscriptions from the original box and cams are stencilled on the top and base of the frame and impressed or painted on the metal cans. The frame has provision for a further drawer. The wooden case and metal tins were made in Australia.Top and base of frame; "THE BRITISH IMPERIAL OIL CO. LTD."

Equipment - Model, 'Model Steam Engine' by Frederick Mitchell, 1886, c1892
Frederick Mitchell was born c1874 at Staffordshire Flat, Redcastle, near Heathcote. His father was an engineer from Cornwall, and had a quartz crushing battery at Staffordshire Flat from 1870 to at least the 1890s. Around 1886 Frederick Mitchell was an 18 year old "Engineer and Instrument Maker". He was awarded an 'Honorary Mention' at the Australian Juvenile Exhibition 1890-1. It was donated to the Ballarat School of Mines Museum in 1892. In the early 1960s the model was transferred to the Heat Engines Laboratory. All Heat Engines laboratory was moved from the Ballarat School of Mines to the Mt Helen Campus on October 1869. The model was accommodated in the thermodynamics laboratory. It was shown working during open days. The Ballarat School of Mines Calendar for 1893, page 66 refers to this item. There is correspondence between Frederick Mitchell's grandson, F.W. Mitchell; E.J. Barker, Director of the Ballarat College of Advanced Education; and Graham Beanland, Ballarat School of Mines.A working model of a vertical oscillating twin cylinder steam engine with fly wheel, mounted on a wood base board and covered in glass.

Functional object - Dorade Cowl, 1930-1940s
A dorade is a type of ventilator that permits the passage of air in and out of the cabin or engine room of a boat while keeping rain, spray, and sea wash out. The basic form is a low, rectangular box fixed to the deck or cabin top, fitted with interleaving vertical baffles. The baffles alternate to be free at the floor of the box, or free at the ceiling, forming a series of chambers. A horn-shaped ventilation cowl is usually fitted facing forward to a large hole at the top of the chamber at one end of the box with another large hole opening down into the boat from the chamber at the other end. Limber holes perforate the wall of the box at the floor of each chamber. Dorade boxes operate on the principle that air can pass relatively freely through the chambers, yet rain or sea wash will be trapped in successive chambers and drain out the small holes in the sides of the box. The first appearance of Dorade boxes was on the Olin Stephens-designed Dorade, a yacht built in 1929 for ocean racing. As originally built, the Dorade's vents led directly below, but this was found to allow water below, and the vents were modified in the early 1930s.An early piece of marine equipment from the 1930s and 40s that still is in use today on smaller vessels and ships.Dorade Cowl (Ventilator), brass casting with wide open mouth twisted to side.

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 -

Equipment - Ship's Telegraph section, A. Robinson & Co. Ltd, Late-19th to mid-20th centuries
The ship’s communication system that was used from the late 19th century to early-to-mid-20th-century is called an Engine Order Telegraph (E.O.T.) or ship’s telegraph. The system has two parts, the Bridge Section and the Engine Room Section. The Bridge Section is usually mounted on top of a pedestal, and the Engine Room Section is often attached to a vertical surface. The standard commands printed or stamped onto the dial are the directions of AHEAD and ASTERN, and the speeds of STOP, SLOW, HALF, and FULL. The ship’s pilot on the Bridge of a vessel sends his Orders for speed and direction to the to the Engine Room with the E.O.T. He moves the lever or levers, depending on the number of engines the ship has, to change the indicator on the Bridge Section’s dial to point in the new direction and speed of travel. This change causes the Orders to be duplicated on the Engine Room Section’s dial and a bell to signal the change at the same time. The engineer then adjusts the ship’s engines and steering equipment to follow the pilot’s Order. The manufacturer, A. Robinson & Co. Ltd of Liverpool, established his business in 1780 and continued until 1968 when the business was purchased by marine products maker Chadburns, established in London in 1870.This Engine Room section is part of a ship's telegraph communication system and represents marine technology used in the late-19th to mid-20th-century. Engine Room Section of a ship’s telegraph or Engine Order Telegraph (E.O.T.). The round brass dial has inscriptions stamped around its edge and centre. Red inlaid glass plates have inscriptions in white paint on them. The inscriptions are nautical terms for direction and speed and include the maker’s details. A rotating pointer is joined to the centre of the dial. The maker is A. Robinson & Co. Ltd of Liverpool.
