“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.

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.

This Johnson Bros. (USA) Locomotive Type Boiler was from a steam shovel (that moved on rails) that excavated rock and soil during the construction of Stevens Weir near Deniliquin NSW in 1934. It has a working pressure of 100psi. This is an example of a fire tube boiler where the fire from the fire box heats the water surrounding the fire tubes running through the boiler, smoke escapes out the smoke stack and the steam is captured in the dome and sent through pipes toward other engines in the Port of Echuca Steam Display. Two glass gauges are fitted on the side of the firebox. Two safety valves are fitted at the top of the boiler to maintain the correct and safe pressure. It still functions today for visitors most days of the week.A good example of the technology and industrial history of the Riverina region of southern NSW and northern Victoria. It is an integral part of the Port of Echuca Steam Display running secondary engines off the steam produced within this boiler.
