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

This image of the Ralph Falkiner’s Mueller Petrol-Electric Road Train was taken in Wodonga in February 1914. Imported from Germany by Mr Ralph S Falkiner in late 1913, the train’s inventor, Major W A Mueller with two assistants, came to Melbourne to assemble then commission the train. The train cost Mr Falkiner about £13,000 plus £4,591 import duties. The Falkiner family were sheep breeders in the Western Riverina and he hoped to use the road train primarily to convey wool to the railways for despatch to Sydney. The train was 216 feet long, weighed 43.5 tons with a top speed loaded of 6-8m/h and petrol consumption up to two gallons per mile. Its first Australian journey was to haul 50 tons of cargo to Edmondson & Co at Wagga Wagga, 277 miles away. The journey from Melbourne was plagued with problems including broken cylinders and crank shaft and overheating as it was not designed for Australian climatic conditions. Three months after leaving Melbourne it arrived in Wodonga. A series of problems between Springhurst and Wodonga, including broken cylinders and valves caused an eight day delay. Some of the cargo was off-loaded in Albury, then after repairs the train continued on to Wagga where it arrived in May 1914. After unloading there, the road train was taken to Mr Falkiner's Groongal Station, near Hay and subsequently made several long trips into drought-stricken areas or the Western Riverina. Eventually the dream collapsed when the engines gave out after the train bogged in the sticky black soil of the Hay plain with 251 bales of wool on board. The train was finally railed back to Melbourne and stored but destroyed when the warehouse burnt down. In this photo, the road train is drawn up outside the Wodonga Stores and Bakery owned and operated by George Leighton. Mr Leighton began his business opposite the Terminus Hotel in Sydney Street, Wodonga in 1885. His business included a general store, stocking groceries, ironmongery, drapery, crockeryware, boots and shoes as well as a bakery. He was very actively involved in the community and served on the Wodonga Council for 18 years including three terms as Wodonga Shire President in 1901 – 02, 1910-11 and 1913-14. He was also Chairman of the Wodonga Waterworks Trust for several terms. Mr. Leighton also took a prominent part in the movement to establish a Public Library in Wodonga. His other involvements including being a Founder of the Wodonga Lodge of Freemasons, Honorary Treasurer of the Wodonga Bulldogs Football Club and Secretary of the Wodonga Racing Club. Mr Leighton passed away in Wodonga in 1916.This image is significant because it records a rare event in Wodonga and an experiment in Australian road transport.Black and white images of the Falkiner Road Train in Wodonga and on its first journey from Melbourne to Wagga, NSW It is taken in front of the Wodonga Stores and Bakery operated by George Leighton in Sydney Street, Wodonga.falkiner electric train, early road transport, high street wodonga, george leighton

The date this photograph was taken is unknown. Estimated date 1960-70s. The gentleman in the photograph and location the photograph was taken are also unknown. Perhaps in the Beechworth or Stanley area. The photo is associated to another record, 6856 as it has the same elderly gentlemen in the image. He is able to be identified through wearing the same clothes and distinctive hat in both photographs. The photograph is associated to mining as the gentleman is standing next to a small mine site where perhaps a windless or whip was mounted over the entrance of the shaft. The windless was a structure mounted over the shaft, fitted with a hand-cranked winch, which was usually constructed from wood that would have been found in the surrounding area.

The photograph printed on this postcard comes from the collection of the Mitchell Library in Sydney. It is sepia in tone and depicts seven men standing and sitting around a mine shaft in the Beechworth region. The photograph has been dated to approximately 1872. This period in history post-dates the Victorian gold rushes which occurred 1852-1853 in Ballarat, Bendigo and Beechworth. During this period, in the 1870s, the surface alluvial gold had been discovered and removed from location. Therefore, in order to reach the deeper and less accessible alluvial gold, diggers began to dig shafts into the earth. These shafts sunk below the ground level by 20 to 30 feet and required timber structures around the entrance and winches to bring the paydirt to the top. The top of this wooden structure is visible behind the man standing in the upper right of the image. This type of mining was highly dangerous as mines often caved in which injured the minors and often resulted in death. Thus, following this period, in the early 1900s, miners opted instead for hydrolic slucing which cut away the earth without the devastating consequences of a mine cave in. This particular group of miners appear to have been unable to afford a horse (then worth around 50 pounds) which were generally used at mines like this to help pull buckets attached to ropes up and down the mine. Instead, this group brought the buckets up and down by windlass. The windlass was a wooden structure mounted over the mining shaft and fitted with a hand-cranked winch which enabled the bucket attached to the rope to be brought up and down.Gold was first discovered in Beechworth in Spring and Reid's Creek in the summer of 1852-1853. At its popularity, this region had approximately 8000 people on the gold fields searching for gold on the banks of these creeks. These periods did not require the use of heavy machinery or the digging of deep mining shafts like the one depicted in this image. Therefore, this image has important connotations for the technologies associated with mining during the approximated 1870s when gold was harder to access. This is a later period in gold history which does not fit into the "gold rush" period. Instead, it occurred after the surface gold had disappeared and therefore, is essential for researchers who are investigating the mining techniques and structures used to reach the alluvial gold which was located deeper under ground in the 1870s. This period predates the use of big heavy machinery used to mine in the 1900s which include dredges. Images such as this one can also impart essential information as to the wardrobe and fashion of men during this period. It also imparts knowledge about the landscape of Beechworth which is useful for people researching the environment and impact of gold mining in the north-east region of Victoria. In addition, since this image is a postcard reproduction of an early Australian image which may date to approximately 1990 it can impart knowledge as to the interests of people during this time period when there may have been an increase into Australian history.A sepia tone facsimile of an early Australian photograph (circa 1872) printed as a postcard.Obverse: BEECHWORTH / Victoria, Australia / Reverse: GM 2 3275 / CORRESPONDENCE / AUSTRALIAN / YESTERYEAR / CARDS / ADDRESS / Published by George Symons (057) 65 3240 / THE MINEHEAD C. 1872 / The easily gleaned gold of the early fields did / not last very long.

This book was owned by Alf Gresham Johnston who was a former SMB mining student from the Ballarat School of Mines. He died at the age of 29 during military service in South Africa. The following is from the Federation Uni Honour Roll at http://federation.edu.au/about-us/our-university/history/geoffrey-blainey-research-centre/honour-roll/j/alfred-gresham-johnston-1872-1901 The October 1901 Ballarat School of Mines (SMB) Students Magazine reported 'Alf. Johnston's gone. The news came as a shock to all of us at the school. He who was with us a few short months ago, in all strength of sturdy manhood, has met a soldier's death in South Africa, and we sincerely mourn his loss…. His heart was in the school, and he did his best to further its interests … His last act on leaving Australian shores was to send a telegram from Albany to Prof. Mica Smith, to whom he was warmly attached, wishing the School and all connected with it "Good-bye". In his short, all to short, life of 29 years, he had more adventure than falls the lot of most men, and possibly the spirit of adventure, and also, of duty, prompted him to throw in his lot with the "colors," and leave for the front. The news of his death comes to us with added weight of sadness when we remember that he was one of the organisers of the School entertainment last year to help swell the fund for the erection of a statue to fallen Victorian soldiers.'A small red book with a double black line bordering the front cover, with the text Longmans Elementary Science Manuals on the bottom of the cover.

The Underwood Motor Manufacturing Co started making 3hp 2-stroke engines, in either marine or stationary styles from about 1946 at 135 Queensberry St, North Melbourne. By about 1949 the 3.5hp 4-stroke engine was introduced. this engine was sold by Baltic Simplex as the Simplex Challenger, replacing the RB&T built S type. By the mid 1950's the firm had shut up shop. In the Sands & McDougall directories of 1948 & 1949 they were listed as Underwood Petrol Engine Co. The following years they were back to Underwood Manufacturing Co. The two-stroke version came in such variations as marine, stationary, tank, hopper cooled and air cooled, each believed to have run on a mixture of 30 parts Standard grade petrol to one part oil. Most but not all water cooled two stroke engines feature a water circulating pump. The 3-4hp four stroke engine used petrol for starting then switched to kerosene when warmed up. Most were 3hp. From a 1947 advertisement the machine was noted with rope start, quickly detachable magneto and the angled spark plug which would have been a marine version with a clutch and hand throttle. The stationary engine had the clutch replaced by a governor. The magneto on these engines did not rotate. it was oscillated by an eccentric on the crank and a link to an arm on the magneto drive shaft. There were other variations including a hopper cooled one with a normal marine base and a chain driven magnet.
