This model was found in the collection of Bay Steamers Maritime Museum. It is not knowt who created it but it is supposed that it was constructed to educate the many masters of the Wattle in the operation of a steam engine - a not so common mode of power these days. A Bay Steamers Maritime Museum examined the model in March 2012 and discovered that is was in poor repair. Using his existing knowledge, and with reference to some historic texts, he made some repairs and returned the model to working order. Here is his anaylsis of the situation as an excerpt from the Bay Steamers Maritime Museum newsletter Steamlines May 2012 "I was confronted with a model of a steam engine used years ago as a training aid for hopeful steam engineers. Already having a knowledge of steam operations, I considered a museum write-up for that model a ‘piece of cake’. However, on turning the model’s crankshaft, the valve timing seemed ‘out of kilter’ with the movement of the piston. Problem was that the two eccentrics on the crankshaft were not properly secured to it. Eventually I fastened the two eccentrics to the crankshaft where I felt that they should be and then realized that one of them had a chain-driven valve-timing device attached. This would be adjusted while an engine was running to achieve best performance and fuel economy whilst in operation by accurately controlling the period of time during which steam under pressure from the boiler would be admitted to the cylinder and give greater time for the steam to expand in the cylinder, move the piston and turn the crankshaft and thus, drive the attached apparatus. When the valves were correctly set up it was then possible to get the model to function properly.The model comprises a green section, which is the actual the model mounted on a brown painted board. There are two parts of the model, painted white representing the steam passages, and black representing the cast- iron portions of the cylinder-block casting, and of the main valve sliding between the cylinder a second sliding valve. Of the black portions, one slides back and forth being connected to a rod which is connected to an eccentric clamped to the crankshaft and is the nearer to the flywheel of two eccentrics. This eccentric is attached to the crankshaft at an angle of 90 degrees to the crank-pin attached to the flywheel. To operate the model simply turn the flywheel by means of the handle attached to its crank-pin. A second eccentric is also attached to the crankshaft, further away from the first eccentric, and it is adjusted to operate 90 degrees from the first eccentric (that is, 180 degrees from the crank-pin) A piston (painted silver) is located in a plastic cylinder and has a piston rod which passes through one end of the cylinder, (in actual practice a steam-proof gland seals the cylinder against loss of steam) terminating in a cross-head slide between four rails guiding it. From this cross-head, a connecting rod joins the piston-rod to the flywheel via the crank-pin attached to the flywheel which is part of the crankshaft. (In actual practice, a flywheel may not be used, particularly in a multi-cylinder engine.) The white portions of the model painted nearest to the cylinder represent the two steam ports cast into the main cylinder block, whilst one section painted in between those two represents the exhaust outlet (which may be connected to a condenser to conserve water, or to the open air). The main slide valve has three white-painted portions painted thereon. It has two white-painted marks representing the steam passages to the steam ports into the cylinder, and a third section in between the other two, being that part of the valve through which exhaust steam passes in line with the ports in the cylinder block. By rotating the flywheel, the operations of an engine will be observed as steam is admitted to the main valve via the gap between the two jaws of two moveable portions of a second sliding valve which is operated by the second eccentric attached to the crank-shaft. This eccentric is used to finely tune the valve timing of this model to obtain best running results of an engine. There are various methods used for reversing a steam engine. model compound steam engine, steam engine, model, crankshaft, valve, flywheel, wattle, engineer, eccentrics

Louis Heinrici, Germany, circa 1900 a small Stirling type hot air engine in which a body of air is worked constantly, being alternately heated and cooled during each revolution of the crankshaft. Heinrici hot air engines are of the valveless, closed cycle type, generally called Stirling cycle engines, after Robert Stirling, the Scottish Presbyterian minister who pioneered their development in the early 1800's. They operate by alternately heating and cooling a quantity of air, called the working fluid, contained in the engine's internal spaces. Heat is applied externally and passes through the cylinder wall, heating the working fluid, which is then expanded against a piston to do mechanical work. After heating and expanding, the working fluid is moved to a cool space where it cools and contracts before being returned to the hot space for the cycle to repeat. It has a displacer (just a loose piston), below and in the same cylinder as the power piston to which it is connected via cranks and linkages so as to lead by 90degrees of crankshaft angle. The displacer space and the piston space are connected by the annular gap around the loose fitting displacer so that the working fluid moves between these spaces and changes volume by the appropriate ratio as the engine rotates. Because they have no valves and experience no sudden pressure changes, Stirling engines are noted for quietness and reliability. Heinricis use air at atmospheric pressure for their working fluid, but for higher specific output (power for size) and better efficiency, modern Stirling cycle engines use pressurised gas- air, nitrogen, helium or hydrogen.Historic - Hot Air Engine - MotorHot Air Motor made of Steel with two drive wheels. a small Stirling type hot air engine in which a body of air is worked constantly, being alternately heated and cooled during each revolution of the crankshaft.

It was the first Holden to incorporate the new "Red" engine, with a 7 main bearing crankshaft instead of the 4 main bearing crankshaft used in the "Grey" engine. The larger capacity 149 ci (2400cc) engine was first only sold attached to a three-speed manual gear box or the "Hydramatic" three-speed automatic transmission with a (column shift). Although the Controlled Coupling Hydramatic used in the EH was actually a four speed, it effectively worked as a three speed unit except at full throttle. The 179 ci (2900cc) engine was initially only sold with the "Hydramatic" three-speed. The first EH with a 179 ci engine and a manual gear box was called the "EH-S4", fitted with an up-graded manual gear box, with stronger gears than the 149ci gear box and an up-graded clutch. The three-speed manual (column shift) gear boxes had no synchromesh on first only second and third 'top gear'It was the first Holden to incorporate the new "Red" engine, with a 7 main bearing crankshaft instead of the 4 main bearing crankshaft used in the "Grey" engine.

This chainsaw was one of the earliest models sold in Australia. It was manufactured by the Lombard company which was established in 1894 when Nathaniel Lombard developed the first practical water wheel governor in Roxbury, Massachusetts, USA. In 1904, the company moved to Ashland, Massachusetts. During the first World War, Lombard Governor produced hydraulic lathes for the manufacture of artillery shells At the conclusion of the war, Lombard expanded into the areas of chain saws and plastic molding injection machines. This model, the L-30 was only produced for 2 years from 1962 - 1964, primarily due to safety concerns and the fact that it did not have any way to sharpen or tighten the chain. This chainsaw was sold by Mann of Wodonga and donated to the Wodonga and District Historical society by David Mann, owner and manager of Mann Wodonga.This item is significant as it was produced for a limited time. It was also sold by a prominent Wodonga business.A single operator chain saw from Lombard, Ashland, Massachusetts, USA. The chainsaw was relatively lightweight but had no safety features such as a chain brake. It was made primarily of sand cast magnesium. The main cylinder was constructed of aluminium with a cast iron sleeve. It had a manual oil pump, the crankshaft operated on ball bearings and it had a maximum rpm of 4,500.

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.

“Sundial 2hp engine, open crank, 600rpm, serial number 6420.” These small 4 stroke engines were widely used on Australian farms through the 20th century to power chaffcutters, grinders, saws, lighting plants, pumps, shearing plants, milking machines and cream separators easing much of the drudgery of farm work. They were also used in garages and workshops and by bush fire brigades. The engine was made by H.V.McKay Massey Harris. At one time Hugh Victor McKay’s Sunshine Harvester Works was the largest factory in Australia but in 1930, to ensure survival during the Great Depression, elected to merge with the Australian arm of a Canadian firm, Massey Harris. The Sundial is fitted with twin flywheels, making it a compact and convenient power source as either wheel could double as a drive wheel. Its connecting rod, crankshaft and flywheel spokes are covered, a safety measure that was not standard at the time. These engines were advertised as simple, dependable, low in price and cheap to run. They had the additional advantage that a bolt-on kit was made by the manufacturer to convert them to run on kerosene. ‘The engine's output is two horsepower (1.5 kW) at 600 rpm. The compression ratio is 5:1 and the spark plug is activated by a high tension magneto. The fuel tank holds 3.3 litres and the cooling water hopper holds 6.6 litres. Cylinder bore is 101 mm and piston stroke is 115 mm.’ In a catalogue of HV McKay Massey Harris agricultural machinery published in March 1942, the engine is described as follows: 'The cylinder head is of the hot, turbulent type, giving the finest fuel atomisation and heat distribution. The carburettor, of special design, has an automatic air valve controlling the amount of air. The supersensitive, high speed, flyball-type governor provides an ample range of speed.'Typical of units used on local farms.

The lathe-making business incorporated in 1902 as Drummond Bros Ltd originated in the fertile mind of Mr Arthur Drummond, said to have been living at that time at Pinks Hill, on the southern edge of Broad Street Common, west of Guildford. Mr Drummond, whose accomplishments included several pictures hung in the Royal Academy, was unable to find a lathe suitable for use in model engineering. In 1896 he designed for himself a ‘small centre lathe … which had a compound slide rest with feed-screws and adjustable slides’. He also designed and built ‘lathes of 4.5 inch and 5 inch centre height, which had beds of a special form whereby the use of a gap piece was eliminated but the advantages of a gap-bed lathe were retained’. Assisted by his brother, Mr Frank Drummond, who had served an apprenticeship to an engineering firm at Tunbridge Wells, the first lathes were made in a workshop adjoining Arthur Drummond’s house. The demand that speedily built up led to the decision to form a company and manufacture the lathes for sale commercially. Land was acquired nearby, at Rydes Hill, and the first factory built. The enterprise was a success, and the company quickly established ‘a high reputation in this country and abroad for multi-tool and copying lathes, and gear-cutting machines’. Other lathes were added to the range, including the first of the ’round bed’ machines for which the firm became widely known. A Drummond 3.5 inch lathe was among the equipment of Captain Scott’s 1912 expedition to the South Pole, and large numbers of 3.5 inch and 4 inch designs were exported to Australia, Canada and India. By the outbreak of war in 1914, 5 inch, 6 inch and 7 inch screw cutting lathes, arranged for power drive, were on sale. Large orders were received from the government for 3.5 inch lathes, for use in destroyers and submarines, and 5 inch lathes for the mechanised section of the Army Service Corps. The latter were used in mobile workshops. The factory worked night and day to supply the forces’ needs, until production was disrupted by a fire which destroyed a large part of the works in May 1915. As soon as rebuilding was complete work restarted. At the end of the war the entire production was being taken by the Government departments, a special feature being a precision screw lathe, bought by the Ministry of Munitions in 1918. Between the wars Drummond Bros Ltd introduced new machines for the motor vehicle, and later the aircraft industry, and the works were extended on many occasions to fulfill the increasing orders. The Maxicut multi-tool lathe (1925), designed for high-production turning operations, was one of the first machines of this type to be built in England. It was followed (1928) by an hydraulic version for turning gear blanks, and similar work. Further developments provided machines which, during the Second World War, turned all the crankshafts and propeller shafts for Bristol engines. Others, ordered by the Ministry of Supply were employed in turning shells, and many other specific needs of vehicle and aircraft manufacture were catered for by new types of Drummond lathes. Production of the small centre lathes ceased during the war when the company needed to concentrate on building multi-tool lathes and gear shapers. After the war a completely new Maxicut range was introduced, replacing the older versions, and fully automatic. The types were continually developed, and new versions manufactured until the end of the company’s life in 1980. The disappearance from the scene of Mr Arthur Drummond in 1946, and the end of the company’s autonomous existence in 1953 when the company was acquired by William Asquith Ltd, which was in turn bought by Staveley in 1966, meant that the factory at Rydes Hill became one – albeit very effective – part of a large national engineering company. Achievements at the Guildford works during its last years included the development of automated Maxicut gear-shapers in what was ‘probably the most fully automated gear shop in the country’, while a machine from Guildford was sent to the Osaka Fair in 1962. In 1963 an agreement was signed with Hindustan Machine Tools for the manufacture of Maxicut gear-shapers in state owned factories in Bangalore and Chandigarh. During 1963 the two largest multi-tool lathes ever made in the UK were installed in Ambrose Shardlow’s works in Sheffield for handling cranks up to 14 foot long. In 1976 Drummond lathes were included in Staveley’s £14,000,000 installation in Moscow of an automated production line for Zil motor cars. Up to the end invention continued at Guildford: a new Drummond Multi-turn memory-controlled machine was shown at the International Machine Tool Exhibition in 1977. This could not save the works from the pressures of the late 1970s, and Staveley Industries closed its Guildford site in 1980.An early example of a lathe that was designed primarily for the hobbyist model maker. It is in good condition and sought today by collectors as many of it's attributes were innovative at the time and lead to further development and incorporation of some of its features into more industrial models of production machinery.
