This Boyle’s machine was made by the British Oxygen Company (BOC) in the 1950’s. The original Boyle's machine was invented by the British anaesthetist, Henry Boyle in 1917. His machine was a modification of the American Gwathmey apparatus of 1912, and became the best known early continuous flow anaesthetic machine. The Boyle’s machine was first made by Coxeter and Sons, under the direction of Lord George Wellesly, which was later acquired by the British Oxygen Company (BOC). Though a lot of changes have been made to the original design of the Boyle’s machine, the basic structure remains the same today.Green trolley on casters with flowmeter and vaporiser bottles attached to a stainless steel cross bar. There is a glass shelf at top of the trolley and a second glass shelf at base of trolley, above a pull out drawer. The pull out drawer contains 4 x black rubber masks, 3 x black rubber tubing connectors, 4 x seals, 1 a black corrugated rubber hose with red rebreather bag, red tube and masonite support board.Tin plate attached to upper portion of trolley: THE / BOYLE / apparatus / BY THE BRITISH OXYGEN CO.

In Australia, the wholesale druggists Fenton, Grimwade and Company, established in 1876, were producing small quantities of oxygen for medical and industrial purposes(11,11). In 1910, they produced a booklet promoting the therapeutic use of oxygen, suggesting it's use in pulmonary and cardiac affections, asphyxia, and morphine poisoning(9). Eventually, oxygen was to play a more significant role in medicine following two significant events. In 1895, Karl Von Linde succeeded in liquefying air, and then fractionally distilling its individual components, including oxygen. This new technique for the production of oxygen from air was revolutionary, but large demand for it did not develop in the wider community until Claude and Hess managed to compress acetylene into cylinders safely in 1897, keeping the highly explosive fuel stable by dissolving it in acetone. By 1900, the oxy-acetylene welding technique was born, and the demand for oxygen for industrial purposes accelerated worldwide. In Australia, Russell Grimwade, working for his father's company, ordered the first oxygen plant to be built in Australia in 1910.

In 1903 the oxyacetylene welding process was developed. Around the same time, new cryogenic air separation processes, based on work undertaken by Carl von Linde and others, replaced the barium oxide process. This paved the way for larger scale and more efficient production. British Oxygen Company, [1905 to 1969] was formally BRIN'S Oxygen Company Ltd from 1886 to 1905. In 1969 it became BOC.
