In August 1884, Alfred Hirst who had started his trade as a watch repairer and was described as a watchmaker extraordinaire established Hirst Brothers and Company, on Union Street in Oldham Manchester. He took his two stepbrothers into the business and the company was set up to produce timepieces and jewellery as well as importing “Limit company” Swiss watches and precision machine tools for the watch and clock trade. By 1902 Hirst Brothers. had become a limited company and was still growing, adding other businesses in Manchester in 1904 and at Birmingham in 1907. The quality of the clocks and watches was such that Alfred Hirst realised his greatest ambition in 1912 with a range of watches which carried the "Limit" trademark. These watch movements had originally been made in Switzerland and shipped to Hirst Bros. to be put into British made “Dennison” cases. This trade brought even more growth with additional sales offices opening in London and Glasgow. At the outbreak of the First World War in 1914 found them manufacturing aircraft parts including revolution counters and optical instruments. The firm had been tasked by the Ministry of Munitions to solve the problem of pilots dropping bombs by hand and as a result, they effectively created the first bomb rack. After the war, the company once again began to prosper and with the demand for their products increasing they looked to build a new purpose-built factory to manufacture their products. In 1917 they purchased a seven-acre field site at Tame Side Dobcross, the designing of the new factory was passed onto local architect AJ Howcroft. His brief for the design of the clockworks would have been prompted by Alfred Hirst who having visited modern factories in the United States was inspired by the latest factory designs providing as much daylight as possible during working hours. The factory was eventually completed in 1920, by the mid-1920s there were cheap clock imports from Germany and production turned to radio sets and other components as well as counter and gas meters for the "Parkinson and Cowan" company who was later to take over the business. In 1926 came the cotton crash and the District Bank who had loans with the company foreclosed on the Hirst loan. The company did survive and throughout the second World, War II were involved in munitions work at the factory as well as making instruments for various aircraft. In the 1950’s they were producing meters and high grade measuring equipment but by the 1970's the business had closed and the factory was demolished in the mid-1980 "s The item is a good example of the later use of an early mechanism “Fusee” that was originally invented around 1525 in Prague. This type of clock mechanism was replaced as watchmakers looked for mechanisms that could reduce the size of clocks and watches, it appears England was the only country to continue making clocks with a Fusee device until around 1900,s of which our clock is an example. The use of a Fusee movement eventually became obsolete in 1970,s. The item is significant for the collection as it is a clock with a movement that has long since been made obsolete. Fusee type gallery wall clock made by Tame Side with an 8-day mechanical fusee movement. The white enamel dial is a little crazed and some of the Roman Numeral numbers are fading due to over-cleaning. The movement has a hexagonal iron pendulum bob hooking onto a pendulum rod with a spring-wound anchor escapement.Only mark is stamped on the movement believed to be a production number "13490" and made in Tame Side.

A sailing block is single or multiple pulleys with one or more sheaves that are enclosed in an assembly between cheeks or chocks. In use, a block is fixed to the end of a line, to a spar, or a surface. A rope line is reeved through the sheaves, and maybe through one or more matching blocks at the far end, to make up what's known as a tackle. The purchase of a tackle refers to its mechanical advantage. In general, the more sheaves in the blocks that make up a tackle, the higher its mechanical advantage. The matter is slightly complicated by the fact that every tackle has a working end where the final run of rope leaves the last sheave. More mechanical advantage can be obtained if this end is attached to the moving load rather than the fixed end of the tackle. Various types of blocks are used in sailing. Some blocks are used to increase mechanical advantage and others are used simply to change the direction of a line. A ratchet block turns freely when a line is pulled in one direction but does not turn the other direction, although the line may slip past the sheave. This kind of block makes a loaded line easier to hold by hand, and is sometimes used on smaller boats for lines like main and jib sheets that are frequently adjusted. A single, large, sail-powered warship in the mid-19th century required more than 1,400 blocks of various kinds and sizes. An item from an old sailing vessel from the late 19th to early 20th century, unfortunately, the item cannot be identified as to what vessel it belonged to. It does however give an insight into a piece of sailing equipment that's design is still in use today on pleasure sailing craft. Wooden closed spelter double rope block with two pully's between sheaves, block has metal frame around outside of the sheaves and 4 metal pins, 2 each side of the frame at top and 2 at bottom, joining the sheaves together.

This textbook was written for engineering students by Scottish Professor, William J Goudie, D. Sc., (1868-1945). He was a member of the Institution of Mechanical Engineers, a member of the Institution of Engineers and Shipbuilders in Scotland, an Associate Member of the Institution of Civil Engineers, James Watt Chair of Mechanical Engineering, University of Glasgow, and Professor of "The Theory and practice of Heat Engines" in the University of Glasgow. He wrote several papers and books on the topics of mechanical speed and power. The publisher firm, Longmans, Green & Co., was originally founded in 1724 in London by Thomas Longman under the name Longman. In August of that year, he bought the two shops and goods of William Taylor and set up his publishing house there at 39 Paternoster Row. The shops were called Black Swan and Ship, and it is said that the 'ship' sign was the inspiration for Longman's Logo. After many changes of name and management, the firm was incorporated in 1926 as Longmans, Green & Co. Pty Ltd. The firm was acquired by Pearson in 1968 and was known as Pearson Longman or Pearson PLC. The first practical steam turbine was built in 1884 by Charles Parsons and this became the beginning of generating electricity and powering large ships. The author of Steam Turbines, Professor William John Couldie D. Sc, was a mechanical engineer who had practical experience in a marine consulting engineering service and lectured in the theory and practice of mechanical engineering.This book is an example of the development of technology that contributed to the evolution of steam turbines. The book is also significant for its connection to the publisher Longmans, Green and Co., of London, a firm that has been established for over two centuries, renowned for publishing encyclopedias, dictionaries, books on English grammar, textbooks, poetry, reference books, novels, magazines and more.Steam Turbines, by William J. Goudie, D. Sc., Second edition, rewritten and enlarged. Published by Longmans, Green & Co. in 1922.

The phonograph is a mechanical device for the recording and reproduction of sound and originally used a tinfoil sheet wrapped around a rotating cylinder to produce the sound. It was invented by Thomas Edison of U.S.A. in 1877 and was the model for all phonographs or gramophones made and developed throughout the 20th century. This machine is of particular interest to the Warrnambool and District Historical Society as it is an Edison phonograph and an earlier model of this phonograph was used in Warrnambool late in the 19th century to make an important recording. In 1896 Thomas Rome, an employee in a Warrnambool boot and shoe shop, purchased an Edison phonograph that could both play and record sounds. At the Warrnambool Industrial and Art Exhibition of 1896-7 visitors to the Exhibition paid a fee to listen to music on this phonograph. But Rome also recorded some local Warrnambool people singing and speaking and these recordings survive today. They are regarded as the oldest surviving recordings made in Australia. Thomas Rome later became a shoe shop proprietor in Warrnambool and was a well-known person in the town/city for a great number of years. This is an Edison Gem Phonograph. It has a black-painted wooden base, now detached from the main mechanism. The phonograph is made of metal which is now heavily rusted. It has a cylindrical turntable for playing the Edison cylindrical records and a handle with a wooden knob. The turning mechanism and belt are now broken. The name of the manufacturer and details of the patents are on a metal plate attached to the side of the phonograph. The amplifier mechanism at the top of the machine is missing. The cover of the machine is made of wood and has a wooden handle attached with a piece of metal and two metal screws. There are also two metal screws on the side of the cover. The cover has a slot on the side to allow the turning handle to be accommodated outside of the cover. The cover is much stained and spotted. ‘Edison Gem Phonograph’ thomas edison, history of sound recordings, thomas rome (warrnambool)

This item was most probably used at the Ballarat School of Mines. Pajari Instruments Ltd. grew from a partnership established in 1945 when the first EX-AX surveying instrument that provided accurate azimuth and inclination was made available to the diamond drilling industry. The partnership between Charles Trotter and George Pajari Sr. was known as Trotter-Pajari Instruments and the EX-AX Instrument was dubbed the "TROPARI" by the diamond drilling industry. Charles Trotter, a mechanical engineer, was also a marketing genius who developed substantial demand in Australia, Africa and South America in the 1940's and early 1950's. In fact the sales to each of these continents exceeded those to North America during those early years. Pajari is located in Orillia, Ontario, Canada and offer services and products that assist customers with their individual requirements. After the death of Charles Trotter in 1956, George Pajari Sr. with the assistance of his wife Hilda continued the business under the title of Pajari Instruments. George Sr. set most of the tenets that comprise our present Mission Statement. If it wasn't user friendly or if it had to have experts to operate it, that instrument design was doomed. If the customer wasn't getting good value in his opinion, manufacturing and repair procedures were examined to see where efficiency could be improved to cut costs without sacrificing Quality. George Pajari Jr and his wife Darlene assumed the reins of Pajari Instruments Ltd. in 1981 when George Sr. decided on semi-retirement. George Jr. brought the "client geologist's" perspective to the company. The company moved from Toronto to a 30 hectare (80 acre) site near Orillia shortly afterward. This site provided the high magnetic latitude earth field environment without magnetic pollution that is necessary for accurate compass setting. The park like setting of this location is a positive psychological benefit for our staff. George Sr. passed away in 2002 being preceded by Hilda only by 3 months, George Jr. continues at the helm of the company. With dedication from long term employees/contractors and third generation family members, Pajari Instruments Ltd. continues operations/new product development in Orillia.

Known as a Tropari - a single-shot, micro-mechanical borehole surveying instrument operated by a timing device. Borehole direction is measured from the earth's magnetic field. The Tropari provides both direction and inclination which can be used to define the attitude of the borehole at the survey depth. Regular surveys at intervals as the borehole progresses will allow a plot of the borehole to be drawn from the data. The Tropari is easy to use and maximizes profits by minimizing capital and operational costs.
