Cocks Pioneer Engine c1930s. Cocks Pioneer Electric Gold & Tin Mine Company was formed in 1899. The company's first power station, located at the eastern end of the valley began operating with its 340 Kilowatt steam-powered generator. By 1909, from 2,500,000 cubic yards worked, reported recovery was 17,284 ounces of gold and 224 tons of tin ore. By 1909, Cocks Pioneer’s power plant had become inadequate and uneconomical. The barge was floated downstream about a mile, but lost time caused the operations to cease. Following testing, a new mine was established by diverting Reid's Creek at a cost of £25 000. Settling dams were built, one of which held 1,,935,900 cubic feet. Sold earth banks, built against a wall of stringy bark saplings constructed and laced with vertical props, were built. In 1914, the company was reformed as Cock’s Pioneer Gold and Tin Mines NL, another power station was constructed at the western end of the township, near the junction of Clear and Reid's Creeks. From 6,800,000 cubic yards of material processed, the returns were 64,397 ounces of gold and 855 ton of tin. Cocks Pioneer mine then moved the barge downs stream and continued sluicing. In 1929 Cocks Pioneer Electric Gold and Tin Mining Company ceased operations due to a drop in values. Cock’s Pioneer Gold and Tin Mines NL carried on large-scale hydraulic sluicing operations until 1941. mining, gold, tin, gold mining, tin mining, machinery, engines, men, cocks pioneer, el dorado, eldorado

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.).

Portable Compound Engine - Marshall & Son's. Builders Number 48317 Built by Marshall Sons & Co., Ltd., Gainsborough, England (Builder’s Number 48317 of approximately 1908/1909), to the order of Robison Brothers, Engineers, South Melbourne. It was used for operating a pump to supply irrigation water at Robinvale in Northern Victoria. Robison Bros & Co. P/L was founded by James McFarlane Robison and his brothers in 1854, initially as plumbers and coppersmiths, the firm expanded into general engineering, boiler-making and brass, iron and steel founders and became one of Melbourne's most important engineering firms. They constructed railway bridges, gold mining equipment, railway locomotives, pumping stations, brewing vessels, abattoir machinery, amongst much else and including the first turnstiles at the Melbourne Cricket Ground. A portable engine is either a steam engine or an internal combustion engine, that remains in one place while operating (providing power to machinery), and can be easily moved from one work site to another. Mounted on wheels or sometimes skids, it is required to be towed between work sites.Historic - Industrial Portable Compound Engine - steam engine - Marshall & Son's.

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.'

This type first flew in 1937 and by the start of WWII it was the preferred aircraft in all Empire Air Training Schemes for multi-engine pilot training. By the beginning of WWII the Airspeed Oxford was the preferred aircraft in all Empire Air Training Schemes for multi-engine pilot training. As of April 2014, no Airspeed Oxfords remain in the world in airworthy condition and there are very few complete air frames. There are reportedly some restoration-to-fly projects underway, one in New Zealand.Full-sized replica of an Airspeed Oxford aircraft. This type of aircraft was described as a multi-engine three-seat advanced military trainer monoplane. It was a wooden construction using plywood and fabric covering and powered by two 375 HP Armstrong Siddeley Cheetah 10 engines. Parts originally used a base for this reconstruction were reckoned to be from an Oxford Mk 2 with registration A25 LX181 which was based at Point Cook and used extensively in training from the Werribee Aerodrome.

Between Pratt & Whitney and numerous licensed companies, there were over 180,000 of these engines manufactured in a number of specifications. The B-24 Liberator would have been their major recipient but other famous aircraft using the same engine were the Consolidated Catalina flying boat and the Douglas DC3/C47/Dakota. Refer Wikipedia link for other aircraft that used this engine.As a result of the significant and ongoing usage of these engines in civil aircraft such as the Douglas DC3, they are by no means rare. Many parts can still be sourced new and there are several companies that have the capacity to rebuild these engines to an airworthy standard.The Pratt & Whitney R 1830 is a double row 14 cylinder air cooled radial engine with a capacity of 1830 cubic inches (30 litres), developing some 1200 horsepower at a maximum 2700 rpm.radial engine, twin wasp, r1830

“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.
