The Archimedes drill, also known as a fretwork drill, is an old type of drill which works on the Archimedian principle; the drill rotates quickly as the barrel on the stem is worked up and down. This tool provides a quick and easy way to bore holes through ordinary fret wood and other substances, smaller versions are used in jewellery making where precision drilling is required. There were numerous different sized Archimedes drills made from various materials, usually a combination of wood and steel, some being all steel and some including brass parts. The fancier versions of these drills included parts made from Rosewood, Ebony, Ivory and decorative brass parts. Some of the later Archimedes drills had technological improvements such as a ratchet device and the inclusion of fly-weights. The ratchet device allows the drill to revolve continuously in the cutting direction. The fly-weights give momentum to maintain the speed of the drill during the upward stroke of the hand. Most old examples have no makers names.A vintage drilling tool, the item therefore could have been used in various industries or professions where precise drilling is required.

How widely the prisoptometer was used is unclear but the Standard Optical Company later patented a new model, The Standard Prisoptometer, on June 21, 1904. Edward Jackson's crossed cylinder technique of determining astigmatism was first detailed in the Transactions of the American Ophthalmological Society (1887)4:595-598. The convenience of Jackson's crossed cylinder lenses over the prisoptometer in weight, cost, portability and reliability meant that they were soon almost universally adopted.This is a rare item as few are known world wide.This instrument is an optometer, that is, a device to measure the refractive error of an eye. It is made of cast iron, steel, brass and glass. It contains a prism which could be rotated, and was used to view a disc or an object circle. The prism caused monocular doubling of the object circle and the separation of the two images varied as the prism rotated, depending on the astigmatism present. The axis of the astigmatism was indicated by the prisoptometer and trial lenses were used to determine the the magnitude of the spherical and cylindrical refractive errorImprinted:"DR CULBERTSON'S PRISOPTOMETER/ GENEVA OPTICAL COMPANY MAKERS, GENEVA, N.Y./ PATENTED SEPT, 21, 1886".

This pulley was found by Geoff Stevenson, on a beach near Cape Conran (east of Orbost). It probably came from a sailing ship which was wrecked there. Pulleys are simple devices for increasing mechanical advantage in a wire, chain or rope system. A pulley consists of a wheel with a specialized rim that rotates on an axle and carries some type of cable or chain. Ships used a variety of blocks (pulleys) for various tasks, such as stowing cargo or handling the sails. A large wooden pulley encased in iron. It was probably used on a sailing ship. pulley cape-conran sailing-ship maritime

This soda syphon is a device for dispensing carbonated or soda water. It was also called a Seltzer bottle. The design of soda syphons used in the 20th century was first created in the late 1830s and these bottles were especially popular in the 1920s and 30s. This Sparklets Company syphon was probably made in England but the company was manufacturing also in U.S.A. and Europe. This syphon has no known provenance but it could have been used in a hotel or a cordial factory in Warrnambool or district. This soda syphon is of interest as an example of how soft drinks were dispensed 90 to 100 years ago. It will be useful for display.This is a heavy glass bottle with a heavy base. It has a metal mesh over the bottle with a metal (or material) red band around the bottle three-quarters of the way up from the bottom. The mechanisms for filling and siphoning at the top are made of metal (these include a funnel and two handles). Attached to the top and inside the bottle is a tube for syphoning. Directions for use are printed on the lid. ‘Sparklets’ ‘Admit gas slowly and shake vigorously’ Important. Do not fill the bottle above the red line’. sparklets company, soda syphon bottle, warrnambool

A mixer is a kitchen utensil which uses a gear-driven mechanism to rotate a set of beaters in a bowl containing the food to be prepared. It automates the repetitive tasks of stirring, whisking or beating. Mixers for the kitchen first came into use midway through the nineteenth century; the earliest were mechanical devices. The mixer with rotating parts was patented in 1856 by Ralph Collier a tinsmith in Baltimore, Maryland .This was followed by E.P. Griffith's whisk patented in England in 1857. A circular tin used for mixing batters. The 2 beaters are of wire, with metal gears, suspended from a metal strip that fits over the tin bowl. and is clamped into place by a metal screw . A crank handle with a wooden black knob attached by a screw is turned by hand to mix the batter in the base. This tin could be secured to a table by a clamp and screw. cooking, kitchen equipment, dairy, cakes, housework, early settlers, pioneers, baking, nutrition, blacksmiths, market gardeners, cake mixers, moorabbin, cheltenham, bentleigh, brighton

Service personnel of the United Kingdom or Commonwealth who are mentioned in despatches (MiD) are not awarded a medal for their actions, but receive a certificate and wear an oak leaf device on the ribbon of the appropriate campaign medal. Lieutenant-Colonel R E (Richard Edmond) Courtney was the Commanding Officer of the 14th Battalion for the period August 1914-1915, including the Gallipoli Campaign. The certificate was signed by Winston Churchill as Secretary of State. It appears to be an official duplicate of the original.Duplicate of original certificate on white paper that has discoloured with age, and is printed on one side in black, endorsed with red typewriting and signed in black ink.On front: typewritten endorsement 'Lieutenant-Colonel RE Courtney 14th Battalion (Victoria) Australian Infantry" and handwritten signature of Winston Churchill.

A boy sits in the board room at the RVIB building in St Kilda Road, holding a Taylor's mathematical slate. Developed by Rev. William Taylor in the mid-late 19th century, this English invention provided a device that allowed pegs to represent a variety of numbers upon an array, rather than using raised numbers. Various models were produced around the world before it's eventual demise around the early 1970's.B/W image of a boy holding a metal grid in his laproyal victorian institute for the blind, braille equipment

Given its sturdy construction, this cane was primarily used as a support device and demonstrates how initially canes which were painted white, retained their existing colour on the crook. Not everyone could afford to have a smooth cane and on this example you can see and feel where branches were stripped off from the main section. These would have also provided a tactile way to identify one cane from another.Short wooden support cane with rubber tipassistive devices, white cane

Gunter's chain (also known as Gunter’s measurement) is a distance measuring device used for surveying. It was designed and introduced in 1620 by English clergyman and mathematician Edmund Gunter (1581–1626). It enabled plots of land to be accurately surveyed and plotted, for legal and commercial purposes. The provenance of this particular Gunter Chain is unknown but it is believed to be used either by the City of Bendigo / Sandhurst or the Lands Department locally when measuring and laying out plots and streets locally. A 66-foot (20.1 m) chain divided into 100 links, marked off into groups of 10 by brass rings or tags. Each link is 7.92 inches (201 mm) long. A quarter chain, or 25 links, measures 16 feet 6 inches (5.03 m) also called a a rod (or pole) measure. Ten chains measure a furlong and 80 chains measure a statute mile. city of greater bendigo surveying

This pamphlet produced by Major Sam Thompson US Army Engineer Corps on exchange to Australia was published as a guide to AUTOMAP 1, the Army Survey Regiment’s first computer-based map production system. It examined how automation had changed the compilation and drafting phases of the map production process. It attempted to present in a light-hearty story telling style, short and clear description of each AUTOMAP 1 sub-system with photos of staff and equipment, diagrams and humorous cartoons. The cartoonist is unknown. The pamphlet was printed at the Army Survey Regiment, Bendigo Army Survey Regiment pamphlet comprises a manilla card cover printed in colour with 24 pages with photographs in black and white; and descriptions, diagrams, and cartoons printed in colour. It is bounded by two staples on its spine. The coloured pages have been scanned at 300 dpi and are stored on a USB Digital Storage Device.
