This equipment was located in the outpatients department (Philip Block) until September 2021 when it was deemed obsolete by Infection Prevention. Hubert Ingham Clements (1886-1969) was an Australian engineer who established his own engineering business in NSW in 1908 manufacturing combustion engines. He became interested in anaesthesia equipment and from the 1920s Clements worked on improving ether apparatus and manufacturing portable suction machines for use in hospital operating theatres. The latter machines were to earn an unrivalled reputation for reliability; many remained in service over thirty years after their date of production. The business became H. I. Clements & Son when his son William joined the company.

Kralcopic Pty Ltd, was a subsidiary of Bendigo-based company GBM Gold and had previously held mining licences around Bendigo, which incorporated sites including Kangaroo Flat, New Moon, Eaglehawk and the associated Woodvale Evaporation Ponds Complex. In August 2019, the Earth Resources Regulator decided not to renew Kralcopic’s three mining licences, due to the company’s inability to provide surety that it could finance its mining activities and site rehabilitation obligations. In October 2020, the company filed legal proceedings in the Supreme Court challenging the decision not to renew these licences. The Supreme Court later upheld the regulator’s decision not to renew the licences. On 23 April 2021, the Federal Court of Australia appointed KPMG as Kralcopic’s liquidators. On 14 May 2021, the liquidator lodged papers with the Australian Securities and Investment Commission (ASIC) to disclaim Kralcopic’s freehold land at Woodvale and parcels of land around the company’s former Bendigo sites, with the land to subsequently become Crown land. The Earth Resources Regulator has put a statutory exemption in place to preclude new mining licence applications on the sites while we undertake rehabilitation. The exemption also provides an opportunity for government to consider future uses of the sites in consultation with the City of Greater Bendigo and the local community. The Earth Resources Regulator holds rehabilitation bonds totalling $5.9 million, which it will use to rehabilitate the former sites.Colour photocopy of original photo.

The clock was the original clock located over the bar in the Orbost Club Hotel. In 1884 J.A. Petterson built the first Orbost Club Hotel with the licence in the name of Thomas Maguire (his stepson). This hotel was the first in the area and cost 1,400 pounds to build (ref. In Times Gone By - Deborah Hall) and was actually built before Orbost was proclaimed a township - April 17 1885 The R A on the pendulum stands for: retard/advance. It is a common pendulum bob, used by many manufacturers, worldwide. Regulator clocks, sometimes referred to as pendulum clocks, were invented in the late 18th century in a quest for greater timekeeping accuracy. They were weight-driven devices. The pendulum on this clock appears to be German made. .The Orbost Club Hotel was the first hotel built in the Orbost district and was an important hub for the township with many whole town meetings held there.A wall clock with Roman numerals inside a dark brown wooden case.

Fifteen year old Albert Edward Gill was born in Poplar, Middlesex, in 1868. He volunteered in May 1883 as an Apprentice Ordinary Seaman with the Merchant Services under the London shipping company James P. Corry & Co., owner of the Star Line. The shipping company by this time had a fleet of both clipper and steam cargo ships that sailed as far away as Australia and New Zealand. Gill’s apprenticeship was a four year unpaid term, with only his food, drink, lodgings, washing and medical needs provided for him. The contract had many conditions but it was a wonderful opportunity for a young man. His father James Gill signed the papers as his guarantor. In December 1887 Gill completed his apprenticeship and qualified as an Able Seaman. He served for another seven years with James P. Corry & Co. and earned his Certificate of Competency as a Master in the Merchant Service in April 1894, having passed the Ordinary Examination. (The transcription of Gill's two certificates is provided further down this page.) JAMES P. CORRY & CO. - The Belfast Company was formed in 1826 by Robert Corry, and imported timber from Canada to Ireland. In 1859 the company expanded to import timber from Calcutta, and relocated its offices to London. In the 1880s the company had a fleet of 13 tall clipper ships and included ports in Australia and New Zealand in its destinations. It continued to expand trade even further and by 1908 the Star Line had seven cargo steamers trading with the East and Far East (the ships were named Star of Australia, Star of Japan, Star of England, Star of New Zealand, Star of Ireland, Star of Scotland and Star of Victoria). In 1912 the Star Line ships added an emigrant service to Australia.

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.

Before the introduction of electricity, lighthouses had a clockwork mechanism that caused the lens to rotate with a light source inside that was either powered by Kerosene or Colza oil. The mechanism consisted of a large weight attached by a cable through the centre of the lighthouse to the top where the cable wrapped around a barrel, drum or wheels that controlled the speed of the lights rotation by a clockwork mechanism. The keeper would crank the clockwork mechanism, which would lift the weight ready for the next cycle similar to an old grandfather clock mechanism. Once the weight lifted to its apex at the bottom of the first landing, the keeper would let it fall, which would pull on the cable, which would, in turn, operate a series of gears activating the rotation of the Fresnel optical lens, which would then rotate to create the lighthouse’s unique light speed of rotation characteristic. Creating a specific characteristic required a way to regulate the speed of the rotation, and was important as sailors could identify a particular light by its speed and time between flashes. The weight had to fall at a certain rate to create the proper rotation speed of the lens and a regulator within the mechanism accomplished this. History: From 1851, Chance Brothers became a major lighthouse engineering company, producing optical components, machinery, and other equipment for lighthouses around the world. James Timmins Chance pioneered placing lighthouse lamps inside a cage surrounded by Fresnel lenses to increase the available light output these cages, are known as optics and they revolutionised lighthouse design. Another important innovation from Chance Brothers was the introduction of rotating optics, allowing adjacent lighthouses to be distinguished from each other by the number of times per revolution the light flashes. The noted English physicist and engineer, John Hopkins invented this system while employed at Chance Brothers. Chance Brothers and Company was a glass works and originally based in Spon Lane, Smethwick, West Midlands England. The company became a leading glass manufacturer and a pioneer of British glass making technology. The Chance family originated in Bromsgrove as farmers and craftsmen before setting up a business in Smethwick near Birmingham in 1824. They took advantage of the skilled workers, canals and many other industrial advances taking place in the West Midlands at the time. Robert Lucas Chance (1782–1865), known as 'Lucas', bought the British Crown Glass Company's works in Spon Lane in 1824. The company specialised in making crown window glass, the company ran into difficulty and its survival was guaranteed in 1832 by investment from Chance's brother, William (1788 – 1856). William owned an iron factoring business in Great Charles Street, Birmingham. After a previous partnership that Lucas had dissolved in 1836, Lucas and William Chance became partners in the business which was renamed, Chance Brothers and Company. Chance Brothers invented many innovative processes and became known as the greatest glass manufacturer in Britain. In 1848 under the supervision of Georges Bontemps, a French glass maker from Choosy-le-Roi, a new plant was set up to manufacture crown and flint glass for lighthouse optics, telescopes and cameras. Bontemps agreed to share his processes that up to then had been secret with the Chance Brothers and stayed in England to collaborate with them for six years. In 1900 a baronetcy was created for James Timmins Chance (1814–1902), a grandson of William Chance, who had started the family business in 1771 with his brother Robert. Roberts grandson, James became head of Chance Brothers until his retirement in 1889 when the company became a public company and its name changed to Chance Brothers & Co. Ltd. Additional information: Lighthouses are equipped with unique light characteristic or flashing pattern that sailors can use to identify specific lighthouses during the night. Lighthouses can achieve distinctive light characteristics in a few different ways. A lighthouse can flash, which is when brief periods of light interrupt longer moments of darkness. The light can occult, which is when brief periods of darkness interrupt longer moments of light. The light can be fixed, which is when the light never goes dark. A lighthouse can use a combination of flashing, oscillating, or being fixed in a variety of combinations and intervals to create individual light characteristics. It is a common misconception that a lighthouse's light source changes the intensity to create a light characteristic. The light source remains constant and the rotating Fresnel lens creates the various changes in appearance. Some Fresnel lenses have "bulls-eye" panels create beams of light that, when rotated between the light and the observer, make the light appear to flash. Conversely, some lenses have metal panels that, when rotated between the light and the observer, make the light appear to go dark. This Dioptric clockwork apparatus used to turn a lighthouse optical lens is very significant as it is integral to a lighthouses operation, we can also look at the social aspect of lighthouses as being traditionally rich with symbolism and conceptual meanings. Lighthouses illustrate social concepts such as danger, risk, adversity, challenge and vigilance but they also offers guidance, salvation and safety. The glowing lamp reminds sailors that security and home are well within reach, they also symbolize the way forward and help in navigating our way through rough waters not just on the oceans of the world but in our personal lives be it financial, personal, business or spiritual in nature. Nothing else speaks of safety and security in the face of adversity and challenge quite the way a lighthouse does.
