The Wodonga Historical Society Haeusler Collection provides invaluable insight into life in late nineteenth and early twentieth century north east Victoria. The collection comprises manuscripts, personal artefacts used by the Haeusler family on their farm in Wodonga, and a set of glass negatives which offer a unique visual snapshot of the domestic and social lives of the Haeusler family and local Wodonga community. The Haeusler family migrated from Prussia (Germany) to South Australia in the 1840s and 1850s, before purchasing 100 acres of Crown Land made available under the Victorian Lands Act 1862 (also known as ‘Duffy’s Land Act’) in 1866 in what is now Wodonga West. The Haeusler family were one of several German families to migrate from South Australia to Wodonga in the 1860s. The photographic equipment in the Haeusler Collection belonged to Louis Haeusler (b.1878). Louis’ photographic equipment is among the many objects in the Haeusler Collection that represent home and social life in early twentieth century Wodonga.This item has well documented provenance and a known owner. It forms part of a significant and representative historical collection which reflects the local history of Wodonga. It contributes to our understanding of domestic and family life in early twentieth century Wodonga, as well as providing interpretative capacity for themes including local history and social history.

Burroughs Adding Machines Ltd of Detroit Michigan was the first company to occupy a factory at Strathleven. During the European reconstruction in the late 1940's Burroughs built a major new factory at Strathleven in Scotland, initially to assemble machines from US-made parts and later to manufacture the full product range for the British and Commonwealth markets. Most of the post-war calculators and portables found in Australia are from the Strathleven factory.This manually operated calculator predates the the rise of the modern computer.A manually operated Burrough's adding machine.

A 'Brunsviga' adding Machine used to educate people who were blind or vision impaired in arithmetic during in the early 1900s. The firm Grimme, Natalis & Co (GNC) was established in 1871 to build sewing machines and domestic appliances at Braunschweig (Brunswick) in Germany. In 1892 engineer Franz Trinks was instrumental in securing the manufacturing rights to the Odhner calculator patents. The first machines were built according to W.T. Odhner's 1890 design, and were distributed under the brand name "Brunsviga". Trinks continued to develop and refine the Brunsviga calculator over a period of almost 30 years. The brass rotor disks are 71mm in diameter, with the nine setting levers spaced on 9mm centres. The moving carriage has 10 places in the counter register and 18 in the accumulator, but the tens-carry mechanism only covers 10 of the 18 places. The carriage is positioned manually by releasing a latch and moving the assembly by hand to the required position. The registers are cleared by a full turn of the large wing nuts on either end. The mechanism is very basic, with no safety interlocks and no added features.Metal machine on wooden base.Brunsviga Patent Braunschweigoffice equipment and supplies, royal victorian institute for the blind

This item was produced for commercial shops and other traders in a period, 1800 to the 1950s. They were used because they were extremely cost effective, speedy, easy to learn and simple to use. It was also at a time before pocket calculators and electric cash tills were produced. The reckoners were a fast and accurate accounting book for a ever increasing bulk purchasing industry. These reckoners were at the start of a business principle "time is money" The reckoner was also looked upon as a way of reducing staff errors in the calculation field. This reckoner was highly valued to a rural industry in the Kiewa Valley because of the bulk produce being bought and sold here. Produce such as milk, tobacco, cattle, timber and fruits relied on weights and quantities calculation for cost pricing. Electrical machines were not of use in "the field or paddock" where important price negotiations took place. For a successful business to keep going accuracy was upper most to producers. It was still a time where honest transactions built reputations and tardiness ruined them. It was a time when a producer's word was his bond and a gentleman's handshake was as good as a contract. This attitude lasted a lot longer in rural regions than in the city. A producer's reputation was based on face to face negotiations and honesty.This hard cover book (blue in colour) contains 210 pages of black numbers and headings on light yellow pages (aged).

Logs were sold to sawmillers from State forest from 1 July 1974 in cubic metres (true volume). Previously sawlogs had been sold on the basis of Hoppus volume. This simple device with two rotating wheels enabled staff in FCV offices to rapidly calculate log volumes from measurements taken in the bush of log girth and length and recorded on paper log dockets. From the early 1980s automated systems became available with the advent of cheap electronic office calculators and simple computers.

A slide rule is an instrument which is used to carry out mathematical calculations. William Oughtred is credited with its invention in 1621, however many others including Isaac Newton have made improvements or modifications over the years. From 1625 to 1800 there were approximately 40 different styles brought forward. with the following 100 years sees over 250 designs created.There have been different versions and modifications to suit scientific, mathematical and engineering requirements. It is interesting to note that many of the buildings of the 19th and 20th centuries have been designed with the use of slide rules. Their use has declined in the last 25-30 years with the advent of computers and specialist calculators.While not directly linked in any way to the history of Warrnambool, this slide rule would have been a item in use by students doing maths at upper secondary level as well as other applications which would make it a familiar object to many people.Coated bamboo with sliding metal framed glass panel or cursor .

J. Mann and Sons was first established as a farm produce store in 1921. The range of products was extended in the 1930s and included groceries and hardware, as well as the first petrol bowser in Wodonga outside the store. After WWII, the premises were extended and the range of products continued to increase. In the 1960s the Mann Family opened a new supermarket in Wodonga, in addition to the hardware business, providing steel, plumbing and industrial supplies, and they employed over 100 people at one stage. With changes in the retail industry, the Mann Family sold the main hardware business to Bunnings and the produce business to the Kelly brothers in 2006.

The Axminster Carpet Loom has been set up as a focal point in the centre of the National Wool Museum. The loom was originally built by Brintons in England around 1910 and was initially operating in Geelong in 1960. Brintons designed and built most of their own looms and ancillary equipment. When superseded in 1975 the loom was donated to the Melbourne College of Textiles for weaving training. The College has now donated the loom to the National Wool Museum and Brintons engineering staff has restored it to full working condition. This loom is known as an Axminster gripper loom. The gripper system was invented by Brintons in 1890 and operates using a gripper shaped like a birds beak. This grips the yarn, the yarn is then cut and the gripper swings down to place the tuft into the woven backing. This particular loom also uses a jacquard system for weaving colours. In jacquard weaving, punched cards are used to instruct the loom as to which colour to use. The system was invented by Joseph Jacquard, a silk weaver from Lyon, and was introduced in 1804. It revolutionised pattern weaving as it had the capacity to create intricate patterns through the use of the cards. By 1833 there were approximately 100,000 power-looms used in Great Britain that had been influenced by Jacquards invention. Joseph Jacquard died in 1834. Charles Babbage was later to adapt Jacquards punch-card system to produce a calculator that was the forerunner of todays methods of computer programmingAxminster carpet loom featuring over 1000 Jacquard punch cards and over 100 bobbins of different colours of wool.loom carpet wool, geelong woolbrokers' association, geelong, auction

George Lee Lawrence (1901–1976) established a firm in Chicago to make slide rules for photography. In 1935 he moved to Wabash, Ind., renamed the company Lawrence Engineering Service, and began to manufacture general purpose slide rules. In 1938 he relocated once more to Peru, Ind., and in 1947 it was changed to Engineering Instruments, Inc., and the company remained in business until its building burned down in 1967. The model 10-B sold for 25 cents during this period. There is no record that Lawrence ever received a patent for any aspect of his design or manufacturing process.Used up to the 1960s prior to the invention of the electronic calculator.10 inch one-sided wooden slide rule painted white on the front face, which consists of two divided scales, one fixed and on movable, and a sliding window called a cursor.

The abacus has been used by many civilisations, and is still in use today. Its origin is masked in the depths of time, but it is believed to have originated in crude form around the years c.2500 BCE. It is interesting to note that this abacus, although in use in Australian schools, contains ten rows, each containing ten beads, suggesting that it was heavily influenced by the decimal system. The number 12 was quite prominent in Australia, no doubt introduced by the British during the first settlements. It's use, as in dozens, twelve shillings in the pound and twelve inches in a foot, was widespread until decimalisation in 1966. Even today, many items are sold in dozens or sixes.Before more sophisticated adding machines and then calculators were developed in the 19th and 20th centuries, the abacus would have been in worldwide use.Abacus or counting frame with ten rows, each containing ten wooden beads.Noneflagstaff hill, warrnambool, shipwrecked-coast, flagstaff-hill, flagstaff-hill-maritime-museum, maritime-museum, shipwreck-coast, flagstaff-hill-maritime-village, wood, abacus
