The book was compiled for the proprietor, L Oertling (Ludwig Oertling), who established his firm of precision scientific instruments in 1849 and went on to become well-known in Britain for its manufacture of precision instruments, particularly its balance scales. In 1865 Ludwig Oertling and business partner Edward Wilds Laad at 27 Moorgate Street London were granted Patent 75 for the invention of improvements in hydrometers. The firm was situated at Turnmill Street, London, in 1922, when it advertised its products including hydrometers, petroleumeters, saccharometers, balances and weights, and automatic coin weighing machines in the British Industries Fair catalogue. In 1925 the firm became part of the Avery group of companies, which acquired Stanton Instruments in 1968 and about two years later Stantons merged into L. Oertling Ltd. Joseph Long has been mentioned by some sources as the author of this book, written for the proprietor of L. Oertling Ltd.The book has been recognised as being culturally important as a basis for our current civilization. It was of great importance to the Board of Revenue for the collectors of taxes and duties Customs Offices, and used in the calculation of alcohol levels in wine and spirits.Reference book, hardcover, burgundy with gold text and lines.

Inventor Biography: Percival Everitt was a Norfolk-born engineer and regarded as the father of the coin-op industry. in 1884 he patented one of his many inventions the coin-operated scales. For many people, it was their first exposure to coin-operated machines. As a young man in 1877, Everitt invented a hay and corn pitcher, a turnip thinner in 1878 and an “Automatic Travelling Anchor” in 1880. But he hit his stride in 1883 with the first postcard-vending machine over a hundred of which he distributed around London. Everitt went on to invent the one penny scale which prompted the formation of the Weighing Machine Company in 1885. Further inventions followed a blow tester in 1887 also the machine for testing a person grip in 1888 and the dispensing machine that opera glasses could be hired from in 1889 also the fortune-telling machine in 1890. He also invented a mechanism to shut coin slots when vending machines were empty, but then as now vandals posed a problem by jamming paper into the slot. Everitt sadly did not make his fortune he died suddenly in February 1893, in his late forties with £71 to his name. Penny Slot Weighing Machine: When the Australian colonies federated to form the Commonwealth of Australia in 1901 their post and telegraph departments were merged to form the national Postmaster General's (PMG) Department. The subject scale is an automatic public weighing machine, No.387, made in England by George Salter and Co. of West Bromwich. The Australasian Automatic Weighing Machine Co. Ltd in 1923 tendered for the right to place Automatic Weighing Machines on railway and tram premises throughout New South Wales subsequently for five-year terms in return for a fixed payment per machine and a portion of the revenue to the NSW Government. The company also made arrangements with the Postmaster General's Department to place machines outside post offices across the country. Weights were measured in stones and pound's up to 20 stone (127 kg) and average weights were shown separately for men, women, boys and girls by various heights in feet and inches. The subject item has had its scale change by the Eastern Scale Company to metric and it is believed to have occurred shortly after April 2000 as the company was first registered and began trading on this date. This weighing machine was originally installed by the Australasian Automatic Weighing Machine Co. Ltd at Warrnambool Post Office and was made by the firm, George Salter and Company, in West Bromwich, England to the Percival Everitt patent. Salter advertised that these machines were suitable for hotels, pleasure gardens, theaters, exhibition halls, clubs, baths and places of public resort. The company had been established in 1760 by the brothers, Richard and William Salter, manufacturing springs and pocket steelyards (spring balances). After several generations, the company was taken over by a nephew, George, and in 1884 the Salter trademark was registered to show a Staffordshire knot pierced by an arrow. The company's expanded range of products included the first coin-operated public weighing machines in the 1880s and in 1895 the first English made typewriter. When the last George Salter died in 1917, the company passed into the hands of other relatives but continued to grow before being bought out by Staveley Industries in 1973. Despite several subsequent mergers, the Salter name continues today on home ware products such as digital scales.A very rare example of a penny in the slot weighing machine imported into Australia and used in public places the item is significant as it gives a snapshot into community life at the time where the public could go and get weighed given there were no personal weighing machines or equipment that people could use at home. So if they needed to post a letter or go on a train journey they could use a machine to check their weight. Whats interesting is that this patent by Percival Everitt was the worlds first slot machine and the start of casino, arcade and other types of slot machines. Personal weighing scale metal large silver painted penny coin operated. Weight measurements are in stones and pounds.
