The Fred Rochow Railways Collection incorporates photos related to the operation of the Wodonga Railway Station including different types of trains and railways staff C. 1930 – 1990. It was donated to the Wodonga Historical Society by Fred Rochow, a railwayman who spent many years based in Wodonga. He joined the Victorian Railways on 17th June l947 and retired in 1988. For some time, he was a member of the Australian Federated Union of Locomotive Enginemen and served a term as a member of the Trades Hall Council. He had an extensive knowledge of the struggles that took place to achieve better conditions for railway workers. Fred worked for many years as a fireman and then worked his way up the ranks to driver, experiencing many changes from the days of steam locomotives through to diesel trains, locomotives and even the modern XPT train. He worked throughout Victoria at different stages of his career, with his final working years focused on the northeast of Victoria and the Albury to Melbourne line. After his retirement, Fred continued to share his love of steam miniature trains with the community.This collection has local and statewide significance as it captures images of trains, locomotives and personnel who operated the railway services in Wodonga and throughout Northeast Victoria. The railways played a critical role in opening up Victoria and connecting Australia for trade, business, social communication and transport.Signal Box B was located on the south-east side of the High Street level crossing and controlled the High Street gates. A big wheel was used to operate the gates. The Signal Box B was demolished on May 10th, 1964, when the standard gauge line to Albury was completed.

The truck has 'MILL ENDS Phone EMERALD 61' painted on the side of the tray, and 'W. J. Hermon/EMERALD/61' painted on the door. There is a manually operated turning indicator – a large white hand shape on a pivoting rod – attached to the door. It appears that the signal is operated through the open driver's window. An unidentified man is in the driver's seat and he is smiling at the camera. Dated 1948.

The A1 Gold Mine is located north of Woods Point, near Jamieson, in the Upper Goulburn region of Victoria. Gold was discovered at the A1 site in 1861 and mining operations began in 1864. The A1 Mine Settlement refers to a small township known variously as Castle Reef, Castle Point, and Raspberry Creek, which developed in the 1860s around mining industry centred on a crushing machine that worked the three gold reefs in the area. Historically, the name "A1"referred to the high quality of gold found in the quartz reefs at depths of at least two thousand feet. Along with the Morning Star mine at Woods Point, the A1 gold mine produced almost sixty percent of Victoria's gold output in the 1950s to 1970s and continued operating until 1992 when it went into administration. Operations at the site were revived in 2016 and the A1 Mine is now considered one of Victoria's premier gold mines. The A1 mine is part of the extensive and prospective Lachlan Fold Belt, a north-west trending belt of tightly folded Early Devonian sedimentary rocks extending from New South Wales to Victoria. Mineralisation is hosted within or immediately adjacent to diorite dykes. Contemporary development of the 'Queens Lode' at the A1 mine signals a move from high-grade, narrow vein airleg mining into larger scale, mechanical mining designed to increase ore production volume. This original, undated photograph of the A1 Mine appears to depict an area or phase of disuse or abandonment. The aged and humble appearance of the cottage suggests association with the historical A1 Mine Settlement, therefore the image may have been taken prior to the 1950s-1970s revival period in which the A1 mine is known to have produced high gold yields. The photograph contributes to our understanding of the A1 Gold Mine's impact on the landscape and the social, environmental impacts of mining on communities and may be compared with others in the Burke Museum's extensive collection of mining photographs to deepen our understanding of mining in the Jamieson area.Black and white rectangular photograph printed on photographic paperReverse: 5577 / A1 Mine / Near Jamieson / Vic. /burke museum, beechworth museum, beechworth, gold fields, gold rush, victorian gold rush, mining tunnels, gold ming history, colonial australia, australian gold rushes, mining technology, beechworth historic district, indigo gold trail, indigo shire, upper goulburn shire, jamieson, woods point-walhalla goldfield, a1 gold mine, victorian high country, modern mining methods, orogenic gold province, gold mineralisation, devonian, dykes

This is a set of 16 photograph of the Royal Australian Survey Corps’ Johnson Ground Elevation Meter (JGEM) Survey Vehicle taken at the Army Survey Regiment, Fortuna, Bendigo. The JGEM vehicle was extensively used by RA Svy within Australia from the late 1960s. A limited number of Ground Elevation Meter (GEM) station wagon type vehicles were manufactured by General Motors Corporation (GMC) in the USA for the United States Geological Survey, Canada’s mapping agencies, RA Svy and National Mapping (Natmap). The GEM was a four-wheel drive, four-wheel steer vehicle. Four-wheel steering was necessary to avoid systematic errors caused by non-tracking of front and rear wheels on conventionally steered vehicles. The manufacturer substituted the rear axle with a front axle and connected them to form the four-wheel steering mechanism. The two Australian GEM vehicles, referred to as Johnson GEMs (JGEMs) were converted into right-hand drive. After delivery in 1964, acceptance Natmap and RA Svy testing and operator training was undertaken at the Army's School of Military Survey located at Balcombe, Victoria. A small fifth wheel was mounted on a cantilever arm suspension midway between the front and rear wheels on the right side of the vehicle. It was lowered to and raised from its operating position by use of a constant pressure air cylinder. A telescopic bar, suspended between the front and rear axles, provided the reference datum for the angle measurement. The wheel provided the velocity or distance signal through a pulse generator system. A sensitive pendulum mounted on this bar provided the angle measurement for each minute distance traversed. The JGEM contained electromechanical instruments used to determine relative elevations, by trigonometric principles, along a traversed path. These relative elevations were obtained through apparatus which measures the instantaneous angle of inclination of the road and the instantaneous velocity of the meter along such a path. Road routes over which the JGEM operated were planned so that each started and ended as near as practicable to an existing point of known elevation (formally referred to as a level traverse bench mark). The difference in height from the bench mark and the road surface alongside the JGEM’s fifth wheel was measured with a level and staff. Along each route, mapping control photo reference points where new elevation values were required were identified on aerial photographs. Under favourable conditions it was possible to survey as much as 160km in an ordinary working day. The first of RA Svy’s JGEM operations was undertaken in 1:250,000 scale map areas of Queensland. CPL John Hook was the JGEM’s main operator in the early 1970s undertaking operations covering 1:250,000 scale map blocks over northern Victoria and central NSW, each requiring 36 points (9 runs of photography and 4 points across. SPR Lyn Thompson and SPR Bob McDonagh teamed with CPL Hook on some of these JGEM operations. When RA Svy was integrated into the Royal Australian Engineers in 1996, the JGEM vehicle with the Survey Corps collection was donated to its museum. It is believed to be the last of the original manufactured fleet in existence. The JGEM has undergone extensive refurbishment to achieve roadworthiness and is currently housed at The Australian Army Museum of Military Engineering, Hoslworthy Barracks, NSW. It can be viewed by making an appointment with the museum’s curator.This is a set of 16 photograph of the Royal Australian Survey Corps’ Johnson Ground Elevation Meter (JGEM) Survey Vehicle taken at the Army Survey Regiment, Fortuna, Bendigo.

This is the 1951 prospectus of the new company known as Leahy’s Electrical Industries Limited and formed from the previous business of Jim Leahy, Electrical Engineer. The business was then and remains today at 82 Fairy Street, Warrnambool . The business of Jim Leahy had been operated in conjunction with Leahy’s Hire Cars and commenced in 1946. This was initially a good business with 25 employees but the building stock and plant were destroyed by fire in 1950 with the business continuing on a limited scale until the new company in 1951 was formed. Jim Leahy purchased the freehold at the corner of Liebig and Koroit Streets and the business prospered from there but today it is based back in Fairy StreetThis prospectus is of some significance as it signals the start of the important business in Warrnambool today of Leahy’s Electrical. The prospectus shows that the original directors were Leahy, Dwyer, Walter, Croft, White and Affleck and they were prominent Warrnambool and district people at that time. This prospectus also has a good summary of the history of the Leahy business up to 1951 and the financial statements etc are of considerable importance to researchers and other readers. This is a typed prospectus of six pages printed back to back and with a buff-coloured cover of lightweight card. The printing on the cover is dark blue.

Information from Norman F. Dalton: Ballarat had a reticulated DC supply in the early part of last century and in 1905 had sufficient generating capacity to enable the trams to be changed from horse drawn to DC electricity. The use of electricity increased with the main power station located on Wendouree Parade, near Webster Street, under the ownership of The Electric Supply Company of Victoria. AC generating plant was installed in 1925 and conversion to AC proceeded. In 1934 the company was taken over by the State Electricity Commission Victoria (SECV) and more AC generation was installed and the changeover of customers was accelerated. This is around the time that the Synchronome Frequency Checking Mast Clock was installed at the Wendouree Parade Power Station. The SECV Annual Report of 1921 states: ::Section 11 of the act directed the COmmission to enquire into the question of securing the adoption of such standards of plant and equipment of a system, frequency and pressure for the generation and distribution of electricity as will admit of the efficient interconnection of undertakings throughout the State. In 1934 when the SECV took over the Ballarat operations the question of linking with the State grid had been a planned operation for some years but due to financial considerations had hindered it and in fact would continue to do so for a further 10 years. So while the need for close frequency control for interconnection was hardly an issue, the need to keep electric clocks correct was important, particularly as this item was a frequent sales point to cover the inconvenience and sometimes expense of converting from DC to AC. The clock is a very accurate pendulum clock with provision for varying effective length during operation for precise time regulation. There are two normal time dials and one is controlled by the pendulum and the other is operated by the system frequency. When the clock was in use it was installed by the MEter and Tests Laboratory and the time was checked daily by radio time signals. The two dials were repeated in the operators control panel in the Power Station. A maximum deviation between the two dials was set in the operating instructions (eg 5 seconds) and the operator would correct this when necessary by remote manual alteration of the turbine governor set point. The clock was used to drive and regulate a system of "slave" clocks which were used to display the time in various locations around the power station. A slave clock is a simple clock which is driven by a small electric motor, its accuracy is regulated by the master clock every 30 seconds to ensure that it and all the other slave clocks in the station are on exactly the right time; slave clocks were placed in various locations, from common rooms to workshops. A master clock could potentially run thousands of slave clocks at one plant. The clock also contains a rectifier. A rectifier is a device that is used to convert AC power to more stable DC current.Two clocks in a timber case. Both are electric, one is powered by the main pendulum mechanism, the other is a self contained electric clock. The main mechanism is of the gravity arm and roller type, which sends an impulse to the slave clocks every 30 seconds. The This Synchronome Frequency Checking Master Clock was used at the Ballarat Power Station. Below the main section of the case is a smaller cabinet containing a rectifier to provide consistent DC power for the clock. The rectifier was made by the Victorian company Hilco, which was located in Burwood. There is a high chance this is not the original rectifier from this clock as there appears to be brackets to hold a larger device in the space the rectifier occupies.Front below main clock face on front of case: "Patented Sychronome Brisbane" Lower left-hand clock face: "Frequency time" Lower right-hand clock face: "Standard Seconds" Synchronous electric clock mechanism on door (Frequency time clock): >200/250 V. 50~ >"Synchronomains" Made in England >Direction indicator for clock starting switch >"To start move lever in direction of arrow and release" >"Patent applied for" Mechanism for "standard seconds" clock: >"English Made" >"Patented" >Serial number "321" >0 above right-hand pillar on front-plate Mechanism for "standard seconds" clock: >"English Made" >"Patented" >Serial number "321" >0 above right-hand pillar on front-plate Mechanism for main clock face: >"English Made" >"Patented" >Serial number "8751" >0 above right-hand pillar on front-plate Inside case, back panel, top enamel plate: >Seconds Battery + Pos. > Battery Common or - Neg. >1/2 min dials Inside case, back panel, bottom enamel plate: external seconds dial Inside case, right hand side, electrical knobs: two switches, both "A.C. mains" Pendulum rod, below suspension spring: Serial number (?) 0000005 Rectifier in bottom cabinet: >"Hilco Rectifier" >"A.C.

The company was originally founded by Frederick Perkins a Russian immigrant schooled in Germany as a machinist and tool and die, maker. Frederick came to the United States in the early 1890s and soon became employed as a machinist for E.W. Bliss & Company in Brooklyn, New York. In the early 1900s, he and a partner began operating a business, F. Persky & Company, Lantern Manufacturer, out of the basement of his house. In 1907, Frederick's son Louis joined him in the business, and together they enlarged both the product line and the manufacturing facilities. By 1912, they had seventeen employees and made a wide range of marine lanterns and products. The business continued operating until 1913 when Frederick became president of National Marine Lamp Company, based out of Forestville, Connecticut. Frederick and Louis left that company in 1916 and moved back to Brooklyn, New York, where they started Perkins Marine Lamp Corporation. Five generations later, PERKO is still a privately owned, family-operated corporation. Perkins Marine Corporation was initially known as Perkins Marine Lamp, Inc. The original focus was on the manufacture of hand-formed sheet metal products for the marine market. The first “Perko” catalogue was published in 1916. It included a full range of kerosene and electric lanterns for small and large boats, ventilators, chart cases, signalling devices, mooring buoys, pumps and a variety of spare parts. These products, fabricated from brass, copper and galvanized sheet metal, began a reputation for producing high-quality products. In 1922, the "PERKO" trademark was instituted with each new product utilising the latest, sophisticated metal manufacturing technology.A significant item from an American manufacturer that specialises in making marine products and is still in business today under the same trade name. The subject item is significant as it was made not long after the trade name of PERKO was registered in 1922 and began to be used on the company's various products.Kerosene lamp with circular fuel tank and chrome plated reflector shield.

Probably acquired for use in Telegraphy courses run at the Ballarat SChool of Mines between 1875 and 1893. Telegraph relays amplified electrical signals in a telegraph line. Telegraph messages traveled as a series of electrical pulses through a wire from a transmitter to a receiver. Short pulses made a dot, slightly longer pulses a dash. The pulses faded in strength as they traveled through the wire, to the point where the incoming signal was too weak to directly operate a receiving sounder or register. A relay detected a weak signal and used a battery to strengthen the signal so that the receiver would operate. This relay was made by the firm of Charles T. and John N. Chester, two brothers who successfully partnered in New York City. Charles (1826-1880) founded the firm and provided the expert telegraphy knowledge while John (1820-1871) kept the books and managed the business operations.(http://americanhistory.si.edu/collections/search/object/nmah_706518, accessed 25/01/2018)Electromagnetic relay device used in telegraphy. The working parts mounted on a brass plate, attached to a wood base. Equipped with four terminal posts. Adjustable contactor mechanism. This electromagnetic Relay Device was used in Telegraphy at the Ballarat School of Mines. After a special meeting of the Ballarat SChool of Mines Council in 1874, a decision was made to offer instruction in Telegraphy, a subject not directly related to mining. Telegraphy was taught by W.P. Bechervaise, postmaster at Ballarat. On 07 October 1874 the Ballarat Courier correspondent reprted on Telegraphic training: "... these classes ... are a snare and a delusion, as there is scarcely the remotest chance of obtaining employment when the examination has been passed."scientific instrument, telegraph relayer, telegraphy relay device, telegraphy
