Forests Commission Retired Personnel Association (FCRPA)Ventimeter, Wind anemometer in cardboard tube
Bushfire behaviour is influenced by many factors including temperature, relative humidity (RH), forest type, fuel quantity and fuel dryness, topography and even slope. But wind has a dominant effect on the Rate of Spread (ROS), as well as fire size, shape and direction. Wind speed can be measured using a variety of anemometers. This simple hand-held Venitimer was made by Elvometer in Sweeden, probably in the 1960s, and was designed for principally for mariners. Some models have a compass in the handle to measure wind direction. The small inlet hole on the side is faced towards the wind and air pressure lifts small plastic disk inside. The upper tube is tapered so that as wind speed increases more air escapes and stronger winds are needed to raise the disk. Wind speed in MPH is read from the side of the clear plastic tube. The waterproof container has instructions on use and conversion scales. Simple and robust device.Hand- held wind anemometer Instructions on use on containerbushfire, forests commission victoria (fcv) -

This timepiece uses raised dots to indicate the position of the numbers, which the wearer could then use to orient themselves and tell the time from the metal hands. The 12 position is indicated by three dots, with the 3,6,9 positions by two dots. The user would start with a finger at the centre of the face and work outwards to the end of each hand to determine position and hence be able to figure out the time. Since the watch is designed and made for touching, the metal hands are particularly robust.Silver fob watch with raised dots to indicate number position. assistive devices, braille -

Vision AustraliaEquipment - Object, Harrison and Seifreid, Hall Braille writer, 1920-1940
The original Hall Braille writer was modelled on the typewriter and was the first successful mechanical point writer. Frank Haven Hall, Superintendent of the Illinois Institution for the Blind, introduced his invention to the public on 27 May, 1892 at Jacksonville, Illinois. It was manufactured by Harrison and Seifried, Chicago, ca 1892. The carriage moves one space to the left as the keys are released. The styli in the embossing heads are controlled by the keys as are the bars on a typewriter. The styli operate from the back so that letters appear in the normal position for reading. Braille writers enable all dots in a Braille cell to be created simultaneously. This model was found in the Braille and Talking Book Library in South Yarra prior to the staff departure in 2000.

Melbourne Tram MuseumDocument - Patent Applications - Trolley Pole safety appliance, Percy Ireland, 1920
Percy Markham Ireland (1893-1976), a tramway rolling stock engineer with the MMTB and a Military engineer applied in 1920 for a patent for a "Trolley Pole safety appliance for electric trams and the like". He was successful in gaining a patent in a number of countries including the UK, France, Germany, Canada, the USA, and New Zealand. The associated documents show the differences in making patent applications in various countries. From research undertaken by the Museum it appears that while his patent applications were successful, his invention was never actually implemented on tramcars in Melbourne". Collected by Noelle Jones as research for an article in the March 2023 issue of the Museum's magazine Bellcord, giving details of Mr Ireland's tramway and military career.

Flagstaff Hill Maritime Museum and VillageEquipment - EPIRB Transmitter
This distress EPIRB unit (Emergency Position Indication Radio Beacon) was found on the beach at Levy's Point, Warrnambool, in December 2000 by a Warrnambool resident. Local police were alerted at the time. This distress signal unit is a world-wide COSPAS/SARSAT, satellite assisted, SAR (Search and Rescue) system for location of distress transmissions emitted by an EPIRB. Offshore cruising vessels must have such a unit as part of its essential safety equipment. This model EPIRB relies on four satellites with orbit times of approximately 100 minutes. Earlier units relied solely on aircraft flying overhead to detect and forward on the EPIRB’s location to Search And Rescue authorities, whereas this new system utilises satellites. An employee from the Lokata firm provided additional information about the Lokata EPIRB units. They had a machined aluminium case with labels that were also made on site. The units could be activated manually or automatically released when a magnetic switch in the case casing was activated. This later model, circa 1983, would have been mounted externally on a vessel's bulkhead in a spring-loaded, stainless-steel protective 'skeleton' mounting, The unit released when the water pressure sensor detected a set time it was under the water, in a similar way that life crafts were released. Each unit was registered to a particular vessel - the vessel's details on this unit are indecipherable. The Lokata Company was established in 1970, designing and manufacturing marine products including communications. The company no longer makes products with the “Lokata” brand. In 2001 Sartech Engineering Ltd. took over the support for the Lokata EPIRB beacons. This emergency location device is a late 20th century invention to help save lives at sea. It adds to the history of maritime life, its risks, the lives lost as sea, and the many inventions aimed as rescuing and saving lives. The local area is notorious for the number of lives lost through shipwreck. It also carries stories of heroic efforts to save lives, and other inventions to help reduce the chance of accidents at sea.EPIRB unit; “Emergency Position Indication Radio Beacon”.

Flagstaff Hill Maritime Museum and VillageInstrument - Clock Parts, Bef. 01-06-1878
The clock parts were discovered in 1980 by Julie Wilkins, a Victorian scuba diver who had already experienced more than 500 dives in Australia and overseas. She was holidaying in Peterborough, Victoria, and looking forward to discovering more about the famous Loch Ard ship, wrecked in June 1878 at Mutton Bird Island. The fast Glasgow-built clipper ship was only five years old when the tragedy occurred. There were 54 people on board the vessel and only two survived Julie's holiday photograph of Boat Bay reminds her of her most memorable dive. Submerged in the calm, flat sea, she was carefully scanning around the remains of the old wreck when, to her amazement, a gold coin and a small gold cross suddenly came up towards her. She excitedly cupped them in her hands and then stowed the treasures safely in her wetsuit and continued her dive. She soon discovered a group of brass carriage clock parts and some bottles of champagne. It was a day full of surprises. The items were easily recognisable, without any build-up of encrustations or concretion. Julie secretly enjoyed her treasures for twenty-four years then packed them up for the early morning train trip to Warrnambool. After a short walk to Flagstaff Hill Maritime Museum and Village, her photograph was taken as she handed over her precious find. She told her story to a local newspaper reporter, lunched a café in town then took the late afternoon train home. Her generous donation is now part of a vast collection of Loch Ard shipwreck artefacts, including the gold watch and the Minton Majolica model peacock. This group of brass clockwork parts is incomplete. The pieces were in the ocean for over 100 years before Julie recovered them from the Loch Ard wreck. Their size would suit the works of a carriage clock, with a mainspring and weight to power the clock movement, a pendulum to measure the clock's speed, arbours, posts, pillars and at least one other plate. They would have been mounted inside a protective case with a small door to easily access the clock face for setting the time and accessing the key's winding hole. The clock cases were usually made from decorative gilt brass with a glass front and a carrying handle. The parts include a weighted second hand with a decorative four-pronged finish at one end, a rounded weight at the other, and a hole for attaching it to the clock face. The gear teeth profiles are ‘cycloidal’, an arch shape with vertical sides, which is common for antique clocks. Modern clockworks have ‘involute’ teeth with sloping sides and a squared-off top. The brass carriage clock parts are an example of a mechanical clock produced in the 1870s. The clock's design is a part of the chain of technological improvements in methods for timekeeping. Its cycloidal gear teeth were the forerunner of the more modern involute gears. The group of clock parts includes a weighted hand or arm for signifying the seconds. This feature was uncommon in portable Victorian-era clocks. The clock parts are also significant for their association with the ill-fated sailing ship Loch Ard, wrecked in 1878. The travelling clock or officer’s clock may have been part of the cargo destined for the 1880 Melbourne Exhibition, or the personal possession of one of the people on board the vessel. Brass clockwork parts from a mechanical clock, sixteen pieces. Parts comprise a plate, large gears or wheels, small pinions or wheels with fine teeth, wheels with cogs, and a weighted second hand. The parts were from a carriage clock ca. 1878. They were recovered from the wreck of the sailing ship Loch Ard.flagstaff hill maritime museum and village, warrnambool, great ocean road, shipwreck coast, loch ard, wreck of the loch ard, 1878, mutton bird island, peterborough, scuba diver, 1980s, shipwreck artefact, relic, clock, mechanical, clock parts, time, timekeeper, horology, chronometry, cogs, time keeping device, scientific instrument, chronometer, john harrison, longitude, carriage clock, coach clock, portable clock, travelling clock, travel clock, traveller’s clock, officer’s clock, weighted second hand, victorian era, cycloidal gear teeth, brass clock, julie wilkins -
