The nested cup weights were designed to make the transport of weights, essential items in most commercial transactions, more convenient. This idea goes back to Roman times. In the nested cup form, a series of weights shaped into cups are set one into the other. Each cup fits precisely into the next, larger sized cup which each larger example weighing exactly twice that of the one previous. The Troy weight system was used for precious metals and gemstones.7 x Brass troy measures of various sizes.

Watches and wristwatches have a glass over the watch face to protect the internal parts, the face and the moving hands from damage. The watch glasses are made in a range of diameters and heights according to the individual watch. A jeweler usually keeps a wide range of glass sizes and sometimes different materials depending on the purpose of the watch e.g. as a fashion accessory or a robust timekeeping piece. The glasses in these boxes have tissue paper between them and most have a label identifying their sizes.These watch glasses are an example of the stock items a watchmaker or jeweler would need to have on hand to service his customer's timepieces. Today's jewelers follow this example to be able to quickly attend to their customer's needs.Three boxes of watch glasses. The collection of circular, slightly domed, clear thin glasses includes different sizes to suit different watches and wristwatches.

A foghorn is a device that uses sound to warn of navigational hazards like rocky coastlines, or boats of the presence of other vessels, in foggy conditions. The term is most often used with marine transport. When visual navigation aids such as lighthouses are obscured, foghorns provide an audible warning of rocky outcrops, shoals, headlands, or other dangers to shipping. An early form of fog signal was to use a bell, gong, explosive signal or firing a cannon to alert shipping. From the early 20th century an improved device called the diaphone was used in place of these other devices, The diaphone horn was based directly on the organ stop of the same name invented by Robert Hope-Jones, creator of the Wurlitzer organ. Hope-Jones' design was based on a piston that was closed only at its bottom end and had slots, perpendicular to its axis, cut through its sides, the slotted piston moved within a similarly slotted cylinder. Outside of the cylinder was a reservoir of high-pressure air. Initially, this air would be admitted behind the piston, pushing it forward. When the slots of the piston aligned with those of the cylinder, air passed into the piston, making a sound and pushing the piston back to its starting position, whence the cycle would be repeated. This method of producing a low audible sound was further developed as a fog signal by John Northey of Toronto and these diaphones were powered by compressed air produced by an electric motor or other mechanical means that admitted extremely powerful low-frequency notes. The example in the Flagstaff collection is an early cased and portable diaphone used on pleasure or sailing craft. By manually turning the crank handle air is produced and fed into valves that direct air across vibrating metal reeds to produce the required sound. in foggy weather, fog horns are used to pinpoint a vessels position and to indicate how the vessel is sailing in foggy conditions. One blast, when sailing on starboard tack and two blasts, when sailing on a port tack and three dots, when with wind is behind the vessel. Since the automation of lighthouses became common in the 1960s and 1970s, most older foghorn marine installations have been removed to avoid the need to run the complex machinery associated with them, and have been replaced with an electrically powered diaphragm or compressed air horns. The example in the collection is significant as it was used in the early 19th century for sailing vessels was important but these portable crank fog horns have also been superseded by modern electric varieties. Therefore the item has a historical connection with sailing and maritime pursuits from our past.English Rotary Norwegian Pattern nautical foghorn within a boxed pine varnished case with exposed corner dovetailing, original leather carrying strap, brass side crank, and original copper trumped horn.

This solid, late Victorian era piano is branded Renardi, which is a German name. In the late 19th century thousands of pianos were exported from Germany to Australia. Some, unfortunately, were amongst the cargo of shipwrecks. It seems that the Renardi pianos were not made by a Renardi company but made to order by any of a number of German piano manufacturer and branded for distribution by Australian music stores.This Renardi piano represents an era where musical gatherings were part of domestic entertainment. Pianos were ialso installed in clubs, public halls and hospitality businesses for song nights and concerts were encouraged for community unity.Piano, upright, walnut veneer with floral design on panels.

Jakob Maul (1866-1953) founded a metal works factory in 1912 at Zell in Odenwald not far from Frankfurt. He was born the son of a winegrower from the Rheinhessen region of Germany that lies on the left bank of the river Rhine. At the age of 45, he started a metal works factory to produce various types of scales but during the second world war the factory was bombed and production ended. Production for the manufacture of scales resumed in 1948. In 1953 at his death Jakobs son Fritz Scharmann an engineer who had been working with his father since 1923 took over the management of the Maul companies. In 1970 the production responsibilities for Philip J Maul was taken over by Porti Office Equipment who was based in Hamburg. The company has undergone several integrations with subsidiary companies. Today the company has diversified into different areas one of which is manufacturing solar scales. An original postal scale made in Germany before the Second World War and regarded today as a collector's item. It is significant as it is a snapshot into the past and how everyday vintage items were used and interacted within society in the 1930s.Antique German Jacob Maul "Concav" brass postal or letter scale, quadrant type, with pendulum, measuring up to 9ozs.

The basic balance scale has been around for thousands of years and its accuracy has improved dramatically over the last several centuries, the principle behind this tool remains unchanged. Its parts include a fulcrum, a beam that balances on it, a pan at the end of the beam to hold the materials to be weighed, and a flat platform at the other for the counter-balancing weights. Balance scales that require equal weights on each side of the fulcrum have been used by everyone from apothecaries and assayers to jewellers and postal workers. Known as an unequal arm balance scale, this variety builds the counterweight into the device. Counter scales used in dry-goods stores and domestic kitchens often featured Japanned or (blackened) cast iron with bronze trims. Made by companies such as Howe and Fairbanks, the footed tin pans of these scales were often oblong, some encircled at one end so bulk items could be easily poured into a bag. Seamless pans were typically stamped from brass and given style names like Snuff (the smallest) and Birmingham (the largest). Some counter scales were designed for measuring spices, others for weighing slices of cake. In the 18th century, spring scales began to appear and would use the resistance of spring to calculate weights, which are read automatically on the scale’s face. The ease of use of spring scales over balance scales. These scales are significant as they identify one of the basic preparation items for the weighing of foodstuff in the family kitchen to prepare everyday meals. This item is significant as it gives a snapshot into domestic life within the average home in Australia around the turn of the twentieth century and is, therefore, an item with social relevance.

A ship's compass played an extremely important role in navigating the ship from the port to its destination. If there was a slight inaccuracy in its calibration the ship could miss its destination and crash or be wrecked. The Falls of Halladale was an iron-hulled, four-masted barque, used as a bulk carrier of general cargo. She left New York in August 1908 bound for Melbourne and Sydney. In her hold was general cargo consisting of roofing tiles, barb wire, stoves, oil, and benzene as well as many other manufactured items. After three months at sea and close to her destination, a navigational error caused the Falls of Halladale to be wrecked on a reef off the Peterborough headland on the 15th of November, 1908. The captain and 29 crew members survived, but her cargo was largely lost, despite two salvage attempts in 1908-09 and 1910. The Court of Marine Inquiry in Melbourne ruled that the foundering of the ship was entirely due to Captain David Wood Thomson's navigational error, not too technical failure of the Clyde-built ship. The Falls of Halladale was built in1886 by Russell & Co., at Greenock shipyards on the River Clyde, Scotland for Wright, Breakenridge & Co of Glasgow. She was one of several designs of Falls Line of ships named after waterfalls in Scotland. The company had been founded between 1870- 1873 as a partnership between Joseph Russell, Anderson Rodger, and William Todd Lithgow. During the period 1882-92 Russell & Co. standardised designs, which sped up their building process so much that they were able to build 271 ships during that time. The Falls of Halladale had a sturdy construction built to carry maximum cargo and able to maintain full sail in heavy gales, one of the last of the 'windjammers' that sailed the Trade Route. She and her sister ship, the Falls of Garry, were the first ships in the world to include fore and aft lifting bridges. Previous to this, heavily loaded vessels could have heavy seas break along the full length of the deck, causing serious injury or even death to those on deck. The new, raised catwalk-type decking allowed the crew to move above the deck in stormy conditions. The Falls of Halladale shipwreck is listed on the Victorian Heritage (No. S255). She was one of the last ships to sail the Trade Routes from Europe and the Americas. Also of significance is that the vessel was one of the first ships to have fore and aft lifting bridges as a significant safety feature still in use on modern vessels today. The subject model is an example of an International Cargo Ship used during the 19th and early 20th centuries to transport goods worldwide and represents aspects of Victoria’s shipping industry. The compass sections are also significant for belonging to the compass of the Falls of Halladale. It was a critical part of the ship's equipment. Compass sections, two; brass disc with a round object on a pedestal, together with a glass disc with a metal frame and insert in the centre.

Before 1851, letters sent through the mail were charged by the number of sheets it contained and the distance it travelled. For example, a letter consisting of one sheet of paper was charged the single rate; a double letter, that is two sheets, was charged double the single rate, a treble letter, was charged three times the single rate, and so on. In other words, each additional sheet of paper increased the charge by one rate. In Great Britain. Sealing a letter in an envelope effectively put an end to postal clerks' ability to count the number of sheets in a letter and an alternative method of determining the postage had to be found. Overweight mailings had previously required the items to be weighed but with the introduction of the Uniform Penny Postage act of 1839, the public could mail a letter not exceeding a half-ounce in weight within the United Kingdom for one penny if prepaid, or two pence if paid on delivery. At about the same time that the adhesive postage stamps and envelopes made their appearance, postal administrations began to experiment with strategically placed street letter boxes, known as pillar boxes because of their round, pillar-like shape, that permitted the public to mail letters from a place other than from a post office. For all these reasons, the use of postal scales became the nucleus of every post office. Scales had been in use since ancient Egyptian times so their use for everyday commerce was not unusual in the 1800s. What was new in 1840 was their ubiquitous use throughout the postal system. No post office could function effectively without one. Although the earliest scales used in post offices did not differ markedly from the ones in general use as time went on they were adapted specifically for postal use. For example, a paper sleeve, also known as a weight sticker, was attached that showed the applicable rate of postage for any given weight. This innovation was quite a time saver as postal clerks no longer needed to weigh the item first and then refer to a separate chart to determine the required postage for that particular weight. Victorian postal scales were used in village Post offices in the late 19th century, of which there are many examples today for sale. No maker can be attributed to the manufacture of the item.

Louis Lachenal manufactured concertinas for C Wheatstone & Co. from around 1848-1858 in a combined home and manufactory in Cheswick, England. He then establish up his own business 'Lachenal's' at 8 Little James Street in London. In 1863 the firm began advertising both 'Anglo and English concertinas, which were more expensive. Lachenal passed away in 1861, so his wife Elizabeth took over the business. The firm was sold to a group of five businessmen in about 1873 and in 1874 the firm became ‘Lachenal & Co.’ A Trade Mark application was made by Richard Ballinger on behalf of Lachenal & Co. on 31st August 1878 and the Number 19,555 was published in the Trade Mark Journal January 8, 1879. The symbol was an English-style reed-shoe with the words 'Trade Mark' and 'English Make'. It was stamped on the right-hand rail (handle) of the Lachenal Anglos, to distinguish them from the German-made ones. It seems that the company ceased business in 1933.This concertina, made in the late 19th to early 20th century, represents the portable musical entertainment of the early settlers in the colony of Australia.

This Sike’s Hydrometer was donated by the Port Fairy Customs Office as it was no longer required by them due to a change in the law. The hydrometer was part of a system for Ullaging or calculating the amount of liquid remaining in a container of liquor such as a barrel, and the amount of alcoholic content in the contents. It can also measure the free space or head space remaining. Hydrometers were used to measure the density, or relative density, of liquids from the late 1600s. In 1816 Bartholomew Sikes won the competition for the most useful accurate hydrometer. Hydrometers were commonly used by distillers, vintners, and brewers to establish accurate measures of alcohol concentration in their beverages. Following this manufacturing process, government inspectors and excise officers used them to check that the labelled indications of alcohol-proof were correct and that the right amounts of duty were being paid.The Sikes hydrometer is of local significance because of its association with the Government's Customs Office in Port Fairy, in the southwest region of Victoria. It is also associated with Bartholomew Sikes, whose design of a hydrometer was chosen in 1816 as being the most useful and accurate hydrometer. The hydrometer has evolved into the digital version available today to measure density of liquids.Sikes Hydrometer and thermometer in a fitted wooden case with crimson lining inside the lid and dark lining in the base. The case has ten vertical pegs to secure the weights. The brass hydrometer has a spherical float and eight thick brass horseshoe-shaped weights.

This representative example demonstrates a mariner’s astrolabe. Historical examples are rare. There are less than one hundred known to exist and most of these have been recovered from shipwrecks, many from Spanish and Portuguese vessels. An astrolabe is a measuring device once used to navigate the seas by observing the sun and stars to measure their altitude. The measurement of altitude could then be used to calculate the ship’s latitude but at that time in history there was no means of measuring longitude. The body of the navigational astrolabe was cast brass and much heavier, and less complicated than the variety used on land. The heavier weight and cut-away shape reduced the effect of the wind and waves when trying to use it at sea. A mariner’s astrolabe or ‘star finder’ is a simplified version than that used by Arabic astronomers to find the altitude of the sun and stars above the horizon, and time of the sunrise and sunset. It is a forerunner to the quadrant, octant and sextant and was popular for about 200 years over the 1500s and 1600s to find the latitude of a ship at sea. The user held the astrolabe at eye level and, usually with assistance, aligned the stars through the two small sights (pinnules), then read the altitude indicated by the pointer on the arm. It could also be used to sight the sun by holding it lower down, aiming it at the sun, and adjusting it until the sun shone through both pinnules. This astrolabe is an example used to demonstrate the mariner’s astrolabe, which was navigational tool of the 1500s and 1600s, in the time before longitude was able to be determined. It is a forerunner to modern navigation technology. Mariner’s astrolabe – a representative example. A gold painted, disc shaped object with cut outs and revolving arm in centre.

First State Watch Factory: This factory was founded in 1930 under orders from Joseph Stalin, the "First State Watch Factory" was the first large-scale Soviet watch and mechanical movement manufacturer in the USSR. Via its USA-based trading company (Amtorg), the Soviet government bought the defunct Ansonia Clock Company of Brooklyn, New York in 1929, and the "Dueber-Hampden Watch Company of Canton", based in Ohio. The soviets moved twenty-eight freight cars full of machinery and parts from the USA to Moscow in order to establish the factory. Twenty-one former "Dueber-Hampden" watchmakers, engravers and various other technicians helped to train the Russian workers in the art of watchmaking as part of the Soviet's first five-year plan. The movements of very-early products were still stamped "Dueber-Hampden, Canton, Ohio, USA" (examples of these watches are very collectible today). In 1935 the factory was named after the murdered Soviet official Sergei Kirov. During the second world war, as the Germans closed in on Moscow in 1941, the factory was hurriedly evacuated to (Zlatoust USSR). By 1943 the Germans were in retreat, and the factory was moved back to Moscow, adopting the "First Moscow Watch Factory" name. In 1947 the first wristwatches under the brand name "Pobeda" and the first Marine Chronometers and Deck watches were produced. By 1951 the production of wristwatches had increased to 1.1 million. In 1975 new machinery and equipment for manufacturing complex watches were imported from Switzerland. The first chronograph called "Okean" (3133) was produced for the space station "Soyuz-23."The Chronometer is of recent manufacture and an excellent example of the type of instrument used to navigate the seas in the 19th century. It is of good quality and of a type regarded as very accurate and well made.

This item was used at the Ballarat School of Mines Physics department until the 1970s-1980s to demonstrate that electrons have a straight line. A sealed conical glass tube, equipped with two electrical connections. One, at the narrow end, terminated inside with a sic shape electrode and faces a cross-shapped aluminium steel target near wide end. Other electrode is side branch, which also provided means of mounting on a polished wood circular stand. A Crookes Tube is an early experimental electrical discharge tube, with partial vacuum, invented by English physicist William Crookes and others around 1869-1875, in which cathode rays, streams of electrons, were discovered. May also be called a Crookes–Hittorf tube or Maltese Cross Tubemaltese cross, crookes tube, physics, electron emission demonstration, cathode rays, vacuum tube, electrons, crookes–hittorf tube, maltese cross tube

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
