This compressor was part of the E.G. Ward Collection. It is connected to the diving suit and boots also in our collection. Siebe Gorman & Company Ltd was a British company that developed diving equipment and breathing equipment and worked on commercial diving and marine salvage projects. The company advertised itself as 'Submarine Engineers'. It was founded by Augustus Siebe, a German-born British engineer chiefly known for his contributions to diving equipment. Siebe Gorman traded as an engineering firm for over 180 years from 1819 to 1999. The early success of the business was due to its founder, the Prussian immigrant Christian 'Augustus' Siebe (1788-1872). For business reasons, he applied for and was granted British citizenship in 1856. He was a gifted engineer who was able to translate theoretical problems into practical, working products. During the industrial Victorian period, the business traded as 'A. Siebe' at 145 High Street Holborn London, but in 1828 new premises were acquired at 5 Denmark Street, Soho. The family firm produced a wide range of manufactured goods including paper-making machinery, measuring machinery, water-pumps, refrigeration equipment and diving apparatus. Augustus Siebe specialised in submarine engineering early on and the company gained a reputation for the manufacture of safe, reliable diving apparatus. Augustus Siebe is best remembered for the development and manufacture of the ‘closed’ Diving Dress based on the ideas of Charles and John Deane, George Edwards and Charles Pasley. Apart from some small modifications to valves and diver communications, the basic 12 bolt ‘closed’ diving dress remained relatively unchanged after the 1870s. Later company successes were also based on innovation, with new products that could be successfully developed and manufactured to high standards. This was largely attributed to the inventive nature, foresight, engineering and entrepreneurial skills of Robert Henry Davis (1870-1965). In 1882, RH Davis joined the company of 'Siebe & Gorman' as a young 11-year-old office boy and he was to remain with the company until he died in 1965. Augustus Siebe retired in 1869 and handed over the company to a new partnership of Henry H. Siebe (1830-1885) and William A. O'Gorman (1834-1904). The new firm traded as 'Siebe & Gorman' (1870-1879) from premises in and around Mason Street, Westminster Bridge Road, Lambeth, London. The two partners soon recognised the potential of R.H. Davis and in 1894, aged 24, he became General Manager of Siebe & Gorman. Davis increasingly ran the company until the surviving partner (W.A. Gorman) died in 1904. The firm was disposed of to the Vickers (armaments) family and a new company 'Siebe Gorman & Co. Ltd.' (1905-1998) was formed. Under the chairmanship of Albert Vickers, R.H. Davis was kept on as Managing Director, and the company forged ahead. However, after WW1, the Great Depression caused manufacturing output and share prices to slump. In 1924 Robert Davis made a deal with the Vickers Board and acquired control of the company through majority shares. Under his leadership, the Siebe Gorman Company flourished and within time, four of his sons also joined the firm. The company gained a worldwide reputation for the manufacture of diving apparatus, decompression and observation chambers, and safety breathing apparatus of all types for use on the land, in the air and under the sea (including mine rescue, tunneling, aircraft, diving, submarine escape and in other hazardous environments). Close research and development links with the MOD (especially the Admiralty), also provided a lucrative outlet for the company products. In 1932, Robert Davis was knighted by King George V, principally for his invention of the ‘Davis Submerged Escape Apparatus’ (D.S.E.A.). Siebe Gorman essentially remained a family firm from the beginning (under A Siebe) until it became a public company for the first time in 1952. However, following WW2, British manufacturing stagnated through stifled investment and post-war austerity, and there was little innovation. Siebe Gorman fortunes began to decline as an ageing Sir Robert Davis failed to invest, or change the company business and management practices. In 1959, Siebe Gorman was acquired by the “Fairy Group” and the ailing Sir Robert was made Life President. Consequently, nothing changed and the slow decline continued until Sir Robert's death in March 1965. Around 1960, Siebe Gorman acquired the diving apparatus manufacturer C E Heinke, and for a brief period, it manufactured some diving equipment under the combined name of Siebe Heinke. Around 1964, Mr. E. 'Barry' Stephens was appointed as the new Managing Director to modernise Siebe Gorman. Changes were made, including a move to a new factory in Wales in 1975. The new company concentrated on fire fighting breathing apparatus and escape equipment, and the move coincided with the loss of many of the older, traditional craft skills. Between 1985 and 1998, Siebe expanded through acquisitions, and several other companies were acquired. The Siebe Gorman (diving apparatus) company has therefore traded as A. Siebe (1819-1870); Siebe & Gorman (1870-1879); Siebe Gorman & Co (1880-1904); Siebe Gorman & Co. Ltd (1905-1998).The compressor is a very significant item as it gives a snapshot into marine history and the development of diving equipment generally especially that used for salvage operations before and during WW2. Siebe & Gorman the company that made the equipment was a leading inventor, developer and innovator of marine equipment with its early helmets and other items eagerly sought after today for collections around the world. The items in the Flagstaff Hill collection give us an insight as to how divers operated and the dangers they faced doing a very necessary and dangerous job during the early days of marine exploration.A single cylinder divers' pump by Siebe Gorman & Co Ltd, London, eccentric hand cranked in brass mounted mahogany case with instructions to the underside of the lid, brass covered pressure gauge and air outlet, brass makers plaque to the front, water inlet and outlet to the rear, green painted lifting rings.

Bib, ill, maps, p.243.non-fictionAustralia's Submariners are a group with an extremely strong sense of identity that goes well beyond occupational comradeship or the esprit de corps of military life in peace or war. Since 1914, the unique skills, attitudes, values and demands of the work they do and the environment in which they do it have forged unparalleled camaraderie. A camaraderie that extends beyond nationality, embracing submariners past and present of every other nation. No one but submariners understand the experience of diving deep beneath the waves in technology filled tubes of steel, each submariner totally dependent on the other for a safe return to the surface. The ethos of Australia's submariners is based upon these factors and remains strong even when they leave the sea and take up other occupations. Australia's future submarines will certainly present challenges in terms of sophistication, technology and capability however the characteristics of our submariners evolved over previous generations will remain much the same; trained and equipped to meet the challenges; just as they have been met and surmounted so many times, in silence, over a century of service.royal australian navy - submarine forces, submarine warfare

After years of precursory surveying, debate and proposals the most ambitious civil engineering project of the day, the Overland Telegraph Line, began construction in September 1870. Superintendent of Telegraphs, Sir Charles Todd led the construction through “terra incognita,” guided by the precursory surveys of John McDowall Stuart and technologies such as his prismatic surveying compass. The unknown and hostile landscape claimed the lives of several men and scores of transport animals in the dogged pursuit of telegraphic connection to the rest of the world. Completed in August 1872, the Line connected Australia to the world via telegraph wires running 3,200 kilometres from Port Augusta in South Australia, to Darwin, then connecting via submarine cable to Java and beyond. The “earth [had been] girdled with a magic chain” according to the then Governor of New South Wales, Sir Hercules Robinson. How does it work? For use in surveying, the sight vane and prism are turned up on their hinge and the instrument is held horizontally either in the palm of one's hand or on a tripod. Two small discs of red and green glass attached to the prism can be flipped down over the sight line to reduce glare. The objective is to bring the subject into the sightline created by the prism, aligning with the thread of the sight-vane until the subject is bisected evenly. Once aligned, the division on the card may be read through the prism. This reading provides the magnetic azimuth, used for calculating the bearings of distant landmarks. Circular instrument mounted in a brass case with glass window and brass lid. The compass card face four black compass points printed on mint green paper; on the underside the magnetic needle would be affixed, all held in place by a brass knob at the centre. The arched labels of "Sawtell" and "Adelaide" and the Prince of Wales feathers appear to have been affixed with adhesive which has since yellowed in the areas of application on the compass card. The compass face is printed with numbers, every 10 degrees from 10 - 360, printed in reverse indicating this compass would have once held a mirror at the sighting bracket. On one side of the brass case is a brass hinged sighting-prism, possibly of ebonite. The sighting-prism is mounted in a hinged brass bracket on one edge of the brass case. It has two flip-type filter glasses (red and green) and folds down into a retracted travelling position. A hinged brass bracket on the opposite edge would have held the sighting bracket - carrying the sighting vane and mirror - which is now missing or removed. Under the hinge is a lever, possibly related to the movement of the bracket. Underneath the brass case is an indented circle with screw threads, possibly for attachment to a tripod, and indistinguishable marks scratched into the surface.Etched on to the centre of the lid, "Sawtell ADELAIDE / No 792." Affixed to the paper compass face, possibly from separate pieces of paper, "SAWTELL / ADELAIDE" with the Prince of Wales Feathers above "SAWTELL". Underneath on remains of white tape in red: "159."surveying, compass, charles todd, overland telegraph line, telegraph
