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.).

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. An oval brass maker’s plate is attached to the top of the case. The dial’s faces have inscriptions that indicate speed and direction, and the front face and plate include the maker’s details. A serial number is stamped on the collar where the dial is fitted to the pedestal. The ship’s telegraph is a Duplex Gong model, made by Chadburn & Son of Liverpool.

William Thomson described a new "Marine Azimuth Mirror" at the 1877 meeting of the British Association for the Advancement of Science, and patented the design in Britain and the U.S. This instrument is an example of the improved design, with a reflecting prism in place of the original mirror. Thomson introduced this form in the early 1880s. The signature indicates that it was made during the period 1900-1913. A child prodigy, William Thomson went to university at the age of eleven. At twenty-two he was appointed Professor of Natural Philosophy in Glasgow where he set up the first physics laboratory in Great Britain and proved an inspiring teacher. He primarily researched thermodynamics and electricity. On the practical side he was involved in the laying of the Atlantic telegraph cable. He was also the partner of a Glasgow firm that made measuring instruments from his own patents.An instrument of significant importance which made marine navigation easier and more accurate in the early twentieth century.An Azimuth mirror with wooden box.Kelvin & Hughs Ltd Serial No - illegible Made in Great Britainazimuth mirror, william thompson, lord kelvin, naviagtion, marine instruments
