In 1902, William E Sessions and other family members purchased a controlling interest in the E.N. Welch Company, a clock manufacturer located in Forestville, Connecticut. Sessions' father owned a foundry located in the town of Bristol, Connecticut that produced cases for E.N Welch Co. On January 9, 1903, the company was reorganized and registered as The “Sessions Clock Company”. Within a few years the Sessions Clock Company was producing clock movements, cases, dials, artwork and castings for their line of mechanical clocks. Between 1903 and 1933 Sessions produced 52 models of mechanical clocks, ranging from Advertisers, large and small clocks with logos of various businesses, to wall, or regulator clocks, and shelf or mantel clocks, designed for the home. Many of the Session clocks from this period are prized by collectors. In 1930, the company expanded to produce electric clocks and timers for radios, while continuing to produce traditional brass mechanical movements. Beginning at the end of World War II Sessions W Model (electric) was widely used by various casting companies for their clocks. The dial of the W Model read Movement by Sessions. In the early 1950s Sessions begin to produce timers for television. In 1956, Sessions was absorbed by a company interested mainly in their timing devices. In 1959, William K. Sessions, grandson of William E. Sessions left the Sessions Clock Company and formed the New England Clock Company. In 1960, one of the Sessions Clock buildings was sold to the Bristol Instrument Gears Company. Kept as the Sessions Company, the new owners ran the operation until 1969 when changes in the market forced the Sessions Company into liquidation. In 1970, the remaining buildings were sold to Dabko Industries, a machine parts manufacturer.The item marks a time when clock production in America was at it’s peak producing clocks for sale in many countries, they were keenly priced, mass produced and available to all. The company had a relatively short life span life regards clock manufacture later diversifying into electric timer mechanisms. Yet it was perhaps inevitable with the advent of electricity along with stiff competition from other clock manufactures that would ultimately herald the end in 1935 of the Sessions company's ability to continue manufacturing mechanical clocks.

There were at least three 1880s vessels named Lady Loch, all built in Victoria; a river launch (ca 1884-ca 1916, originally named Lady of the Lake), a steamer ferry (1884-1920s) and a government lighthouse tender steamer HMV Lady Loch (1886-1962.) The spring balance scale was part of the equipment on the HMV Lady Loch. The scale was made by the renowned company Salter Weighing Machines in the United Kingdom. It was made to Silvester's patent design. Salter Weighing Machines, Britain, began making spring scales in the 1820s. In 1908 Salter opened up an Australian branch named Salter Scales Pty. Ltd. The scale, marked HMV SS Lady Loch, would be suspended by its top ring, a basket or other container is hung from the hook, and the items inside the basket then pull downwards on the hook, which stretches the springs inside the works. The pulling action moves a rack and gears a calculated distance and the gears turn the pointer on the dial to indicate the weight of the goods. This scale measures up to 200 pounds capacity. The HMV SS Lady Loch was an iron steamship built in Footscray, Melbourne, by Campbell, Sloss and McCain in 1886 for the colonial Victorian government’s Department of Trade and Customs. It was armed with a 6-inch gun and two 1-inch Nordenfelt guns. The Sydney Morning Herald of 27th January 1888 describes the vessel in detail. It even comments on the interior of the Saloon “The wood work … is on a very elaborate scale and is exceedingly neat …”. The HMV Lady Loch performed Customs duties, and serviced the lighthouses along the coast. The scale could have measured goods for the Customs Tax, or for measuring out supplies for the lighthouse keepers. The vessel was named after Lady Elizabeth Loch, wife of Sir Henry Loch, Governor of Victoria from 1884 to 1889. In 1932 Lady Loch was converted to a hulk and used in Brisbane, and finally scuttled in 1962 at Moreton Bay, Queensland.The scale has importance due to its connection to the 1886 HMV Lady Loch, a vessel of great significance to Melbourne’s shipbuilding industry. It was the largest auxiliary vessel in the Victorian Colonial Government’s fleet and the first prominent vessel launched by Melbourne’s shipbuilding industry. The scale is also important for its connection with the colonial navy's Custom's work, as the scale was available to weigh goods that could attract taxes and deal out goods for distribution to lighthouse keepers. The HMV Lady Loch was also important part of Victoria's maritime history for its communication and support of the lighthouse keeper's along the coast of Victoria.Scale; Salter's spring balance mechanical hanging scale, brass and iron. Equally spaced marks around the circular dial have values from 0 to 200 in increments of 10, each increment is also divided into 10. An iron ring is attached to a fitted loop on the top of the scale, and an iron hook is attached to the fitted loop onthe bottom of the scale. A moving pointer attached to the centre of the dial has a calibration screw joined to its base. Four screws fix the brass face to the works at the back. There are stamped and embossed inscriptions.

Fob (or pocket) watches were developed in Europe in the 16th century and gained wide usage during the mid 18th century until World War 1 when the wristwatch was invented. These watches were designed to be carried in a small pocket and attached through the means of a 'fob' which could be a chain or made from a variety of materials such as leather. Their popularity peaked in the nineteenth century where they were an important part of middle and lower class society as well. The inclusion of the word RAILWAY on the face of the watch suggests a possible use by an employee of the railways. This item is of social significance as fob / pocket watches were valued as an essential object in all levels of society. For some occupations, such as the railroads, it was a necessary tool of the job. Steel Railway Lever open face pocket / fob watch dated 1920s-1930s. The white dial has large black arabic numerals and outer minute divisions around the edge. A circular insert and small hand to show the seconds is at the bottom of the watch face. The hour hand is a rounded leaf shape, and the minute hand a thin diamond shape. Both hands and the small rounded end of the second hand reflect a metallic blue sheen in the right lighting. The words RAILWAY LEVER, 15 JL and SWISS MADE are on the dial. The lever set on watches was a requirement for railroad watches. It required a two step process for the hands to be adjusted. 15 JL refers to the movement being a 15 jewel one.The front dial of the watch has the words 15 JL, RAILWAY LEVER, and SWISS MADE. flagstaff hill maritime museum and village, warrnambool, great ocean road, shipwreck coast, fob watch, pocket watch, watch, horology, time keeper, swiss made, railway lever, 15 jl, 15 jewel

Galvanometers are an instrument used for detecting and measuring electric current. They had a magnetic needle moved by the magnetic field produced by coils carrying the current to be measured, and the earth's field had to be taken into consideration. They were used to detect current in either direction in telegraphy systems, and to test equipment.Post Office Galvonometer.

James Henry Steward (1817–1896) established J.H. Steward in London in 1852. As “Head Optician” he would have been a qualified oculist but little is known about the founder’s early life and scholastic achievements. However, given the variety of disciplines for which he undertook he was also an accredited instrument maker,he clearly was a gifted scholar and quickly gained professional recognition in a full range of fields for an instrument maker of his day. J.H Steward became incorporated as J.H. Steward Limited on 1st February,1913. The business grew from modest beginnings. Steward would sell pocket watches and assorted items at the annual competition days of "The National Rifle Association of the United Kingdom(NRA)" from a stall. As the governing body for full bore rifle and pistol shooting sports in the UK. The Association established in 1859 with the aim to improve the shooting skills of the newly formed corps of volunteers to meet the perceived threat of an invasion by the French. J.H. Steward advert first appeared in the NRA competition program of 1865. The NRA meetings were held at first on Wimbledon Common, Surrey until 1889. Then because of pressure by the local community, the NRA along with its buildings and its flourishing meetings moved further south to Brookwood, Surrey. By now the Steward operation had grown from a modest stall into a large marquee selling various optical and scientific instruments at these meetings. Throughout its long trading history the J.H. Steward company and many members of the family maintained strong ties to the NRA and competition shooting events. The NRA records show that at the end of the 19th century the NRA bestowed a Life Membership on 7 Steward family members. First presented by J. H. Steward Ltd. in 1902 was the “Steward Trophy” that is still an annual competition for teams of four from any rifle club affiliated to the NRA. There is also evidence that many family members were fine shots.The item was made by a significant instrument manufacturing company that concentrated during the middle 19th century on supplying the British military. This items pattern & design is still available as a reproduction, available on the internet. However this original seems unique as the writer cannot find another for sale or in a collection to date. The assumption is that this type of compass was made for the British artillery units given the sun dial.

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.

The ship's log part, called a fish, is likely to be from a mechanical taffrail log system. It was recovered from the wreck site of the barque, the 1840-1852 Grange. There are no marks on the fish to identify its maker or model. It is part of the John Chance Collection. This ‘fish’ is part of an early to mid-1800s ship's log. It would likely have been part of a taffrail log connected to a rotor (also called propeller, spinner) by a strong line, and the other end connected by a line to a dial mounted on the taffrail, or stern rail, at the stern of the vessel. As the propeller rotated through the water it would spin the log, which in turn would cause a number to register on the dial, showing the current speed in knots; one knot equals one nautical mile per hour. TAFFRAIL LOGS A taffrail log is a nautical instrument used for measuring the speed of a vessel, providing vital navigational information to be calculated, such as location and direction. A log has been used to measure the speed of a vessel since the 1500s. A simple piece of wood was tied to a long line and thrown into sea at the back of the vessel. The rope was knotted all along at equal distances apart. On a given signal the log line was pulled back into the vessels, the knots counted until the log came up, then the figures were calculated by a navigator In 1802 the first successful mechanical log available for general use was invented by Edward Massey. It had a rotor 'V' section connected to a recording mechanism. The water’s movement rotated the rotor, which intern sent the movement to the recorder. There are examples of this invention available to see in some of the maritime museums. Thomas Walker, nephew of Edward Massey, improved on Massey’s design, and Walker and his son took out a patent on the A1 Harpoon Log. In 1861. Both Massey and Walker continued to improve the designs of the taffrail log. New designs were still being introduced, even up to the 1950s. THE GRANGE, 1840-1858- The wooden barque ’Grange’ was a three-masted ship built in Scotland in 1840 for international and coastal trade. On March 22, 1858, the Grange set sail from Melbourne under Captain A. Alexander, carrying a cargo of ballast. The barque had left the Heads of Phillip Bay and was heading west along the Victorian coast towards Cape Otway. The ship struck Little Haley’s Reef at Apollo Bay due to a navigational error and was stuck on the rocks. The crew left the ship carrying whatever they could onto the beach. Eventually, the remains of the hull, sails and fittings were salvaged before the wreck of the Grange broke up about a month later. About 110 years later, in 1968, the wreck of the Grange was found by divers from the Underwater Explorers Club of Victoria. They were amazed to find a unique, six to nine pound carronade (type of small cannon) and a cannonball on the site. There have been no other similar carronades recorded. In that same year the anchor of the Grange was recovered by diver John Chance and Mal Brown. The ship’s log is significant historically as an example of hardware used when building wooden ships in the early to mid-19th century. The ship’s log is historically significant as an example of the work and trade of blacksmith. The ship’s log also has significant as it was recovered by John Chance, a diver from the wreck of the Grange in the 1968. Items that come from several wrecks along Victoria's coast have since been donated to the Flagstaff Hill Maritime Village’s museum collection by his family, illustrating this item’s level of historical value. The ship’s log is historically significant for its association with the 1840s wooden barque, the Grange. The Grange is an historical example of a Scottish built vessel used for international and coastal trader of both cargo and passengers in the mid-19th century. The Grange is an example of an early ship, designed with a wooden hull. It is significant as a ship still available to divers along the south coast of Victoria, for research and education purposes. The Grange is an example of a mid-19th century vessel that carried a weapon of defence onboard. Ship log fitting, called a fish; part of a brass navigational instrument, likely to be from a taffrail log. The metal is a tan colour and has rough surface with a sheen, and discolouration in places. Its basic shape is a hollow cylinder with ends tapering to a smaller size. In the centre there are opposing openings cut out, showing a rough texture inside. One end on the cylinder is closed with a ring and shank installed, fixed by an embedded screw through the end of the cylinder.

This is the Bridge Section of a ship’s telegraph and is a Duplex Gong model, made by Chadburn & Son of Liverpool. This duplex gong model would sound two signals whenever the navigational commands were given by the ship’s pilot to change the speed or direction. The ship’s telegraph was installed on Flagstaff Hill’s exhibit of the 1909 Hobart, Tasmania, ferry “SS Rowitta” installed in 1975 and enjoyed for more than 40 years. Communication between the ship’s pilot and the engine room in the late 19th century to the mid-20th-century was made with a system called an Engine Order Telegraph (E.O.T.) or ship’s telegraph. The equipment has two parts, the Bridge Section and the Engine Room Section. The Bridge Section is usually mounted onto a pedestal, and the Engine Room Section is attached to a vertical surface. The standard marine commands are printed or stamped around the face of the dial and indicated by a pointer or arrow that is usually moved by a rotating brass section or handle. The ship’s pilot stationed on the Bridge of a vessel sends his Orders for speed and direction 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 or bells to signal the change at the same time. The engineer then adjusts the ship’s engines and steering equipment to follow the pilot’s Order. CHADBURN & SON, Liverpool- Chadburn Brothers, William and C.H., were joint inventors and well-established makers of optical and scientific instruments and marine gauges. The firm was granted the Prince Albert Royal Warrant in the late 19th century. In 1870 William Chadburn applied for a patent for his navigational communication device for use on ships. By 1875 Chadburn & Son was producing the brass Engine Order Telegraph in its plant at 71 Lord Street, Liverpool. In 1911 the ship RMS Titanic was launched, fitted with Chadburn & Sons E.O.T. The Chadburn Ship Telegraph Company Limited was registered in 1898 to take over Chadburn & Sons. In 1903 a large factory at Bootle, near Liverpool, and their products were being sold overseas. In 1920 electric-powered telegraphs were developed. In 1944 the name changed to Chadburn’s (Liverpool) Limited. In 1968 the company became Chadburn Bloctube Ltd. In 2000 the company, now Bloctube Marine Limited, was still manufacturing ship telegraphs. SS ROWITTA: - The 1909 steam ferry, SS Rowitta, was installed as an exhibit at Flagstaff Hill in 1975 and was enjoyed by many visitors for 40 years. Rowitta was a timber steam ferry built in Hobart in 1909 using planks of Huon and Karri wood. It was a favourite of sightseeing passengers along Tasmania’s Tamar and Derwent rivers for 30 years. Rowitta was also known as Tarkarri and Sorrento and had worked as a coastal trading vessel between Devonport and Melbourne, and Melbourne Queenscliff and Sorrento. In 1974 Rowitta was purchased by Flagstaff Hilt to convert into a representation of the Speculant, a historic and locally significant sailing ship listed on the Victorian Heritage Database. (The Speculant was built in Scotland in 1895 and traded timber between the United Kingdom and Russia. Warrnambool’s P J McGennan & Co. then bought the vessel to trade pine timber from New Zealand to Victorian ports and cargo to Melbourne. It was the largest ship registered with Warrnambool as her home port, playing a key role in the early 1900s in the Port of Warrnambool. In 1911, on her way to Melbourne, it was wrecked near Cape Otway. None of the nine crew lost their lives.) The promised funds for converting Rowitta into the Speculant were no longer available, so it was restored back to its original configuration. The vessel represented the importance of coastal traders to transport, trade and communication in Australia times before rail and motor vehicles. Sadly, in 2015 the time had come to demolish the Rowitta due to her excessive deterioration and the high cost of ongoing repairs. The vessel had given over 100 years of service and pleasure to those who knew her. This Bridge section of a ship’s Engine Order Telegraph, used with an Engine Room section, represents late-19th century change and progress in communication and navigation at sea. This type of equipment was still in use in the mid-20th century. The object is significant for its association with its maker, Chadburn & Son, of Liverpool, a well-known marine instrument maker whose work was recognised by English Royalty, and whose products were selected to supply similar equipment for use on the RMS Titanic. This ship’s telegraph is connected to the history of the Rowitta, which was a large exhibit on display at Flagstaff Hill Maritime Village from the museum’s early beginnings until the vessel’s end of life 40 years later. The display was used as an aid to maritime education. The Rowitta represents the importance of coastal traders to transport, trade and communication along the coast of Victoria, between states, and in Australia before rail and motor vehicles. The vessel was an example of a ferry built in the early 20th century that served many different roles over its lifetime of over 100 years. Bridge section of a Ship’s Telegraph or Engine Order Telegraph (E.O.T.). The round double-sided, painted glass dial is contained within a brass case behind glass. It is fitted onto an outward tapering brass pedestal with a round base. The brass indicator arrows between the handles point simultaneously to both sides of the dial when moved.

Provenance not clear. Leather case has 'MMBW' inscribed in black pen, indicating an association with Melbourne Metropolitan Board of Works. Item has been in the possession of Terry McCormack since 1972Hand held brass pocket inclonometer level, circa 1920. Leather case for safe storage. Semi circular graduated dial with 90 degree vernier scale with a small (20mm) magnifying glass to aid reading the vernier scale. Above the body, mounted at the rear of the graduated dial, is a spirit level tube which is tilted by finger movement to the milled hand wheel. The height to be determined is sighted through the instrument eyepiece and the bubble tube is tilted until the bubble, viewed in the mirror inside the sighting tube, is brought level with the graticule sighted at the top of the subject object. An angle is thus obtained and by measuring the distance on the ground to the object, trigonometry can be applied to determine the height of the object.Herga & Co. BRISBANE. Made in England
