Standard diving dress (also known as hard-hat or copper hat equipment, or heavy gear) is a type of diving suit that was formerly used for all relatively deep underwater work that required more than breath-hold duration, which included marine salvage, civil engineering, pearl shell diving and other commercial diving work, and similar naval diving applications. Standard diving dress has largely been superseded by lighter and more comfortable equipment. Standard diving dress consists of a diving helmet made from copper and brass or bronze, an air hose from a surface-supplied manually operated PUMP or low pressure breathing air compressor, a waterproofed canvas suit, a diving knife, and weights to counteract buoyancy, generally on the chest, back and shoes. Later models were equipped with a diver's telephone for voice communications with the surface.Hand operated divers air pump for one or two diversdiving, air pump

The donor's father (William Clarence Christopher) was born in 1906 in Williamson Street, Bendigo and was schooled at the Bendigo School of Mines. The notebook on theoretical Carpentry must date from around 1920 when he was an apprentice. His brother James Charles Christopher was a teacher, the Solid Geometry drawings date from 1925-1932 and were submitted by students at Ballarat Junior Technical school. The book od building regulations was used by William Clarence in the 1940's and 50's while employed as a building foreman at Braybrook by Industrial Engineering Ltd.The manuals are covered with brown paper and the title in red or black texter on the front. The theory Carpentry is handwritten, the three Solid Geometry are made up of individual drawings and the Uniform Building Regulations is printed.technical books, school of mines

These are sales photographs for William Tatham Ltd. of Rochdale. These photographs are taken in the fitting shop at William Tatham Ltd. where final assembly would have taken place. The Automatic Feeding Machine automatically dispenses wool to a carding machine, so that an even, constant supply is received. This eliminated the manual labour previously needed for the initial weighing and feeding of wool. The photographed machine was made by William Tatham Ltd, a textile engineering company based in Rochdale, UK. Established in 1866, Tatham developed innovative textile machinery and sent their products to Australia and other countries around the world.Two black and white photos of an Automatic Feeding Machine in a landscape format.

Machine Maker Front bottom right corner - 1146 Rear - 78” wide Automatic Feeding Machine having Dual Hoppers in which the first and large section feeds the second Hopper so as to maintain a constant level of material in the latter. The driving of both spiked lattices is by electro-magnetic clutches, the one in the first Hopper being actuated by a sensitive feeler motion in the second, the second spiked lattice however, being controlled, of course, from the Scale Pan. Through a mercury switch. The scale is of our latest super-sensitive pattern mounted diagonally across the Feed. Only the opening doors are used in the actual weighting and the trap doors placed over the scale which close immediately the correct weight is deposited, operate through a solenoid. The machine incorporates many other features and is arranged to divide for facility in cleaning. 8037.2 - Front mide right edge - Wm. TATHAM Ltd. ROCHDALE.

A collection of 5 manuals for a range of Clyde Diesel Locomotives. The collection includes instructions for the Clyde G8B, G16C, G26C, 1800 HP Model A and the Clyde Mailiner Model 2. On the cover of each manual, the owner has written the letter for the name of class which the relevant locomotive was ascribed in Victoria. The Clyde Engineering Company Limited was registered on 30 September 1898 in New South Wales. It was one of the iconic Australian engineering firms whose history spanned just over a century and was one of the few locomotive and rolling stock builders in the world that transitioned from steam to diesel to electric traction. The company was formed by Walter Maplesden Noakes who purchased the works of Hudson Brothers Limited in the Sydney suburb of Granville, which had been established by in 1882. The manuals refer to the following locomotives:- Clyde Model G8B which operated in Victoria as the new T class locomotive. It was introduced in 1955 and was the most numerous class of diesel locomotive used in Victoria. This model continued in operation until 1968, although many were modified for continued service. Clyde Model G16C, later superseded by the G26C operated in Victoria as the X class locomotive between 1966 and 1976. Clyde Model 1800HP Model A became the S class locomotives in Victoria. Additional numbers were purchased in preparation for the opening of the standard gauge line between Melbourne and Albury, They entered service between 1957 and 1961. Clyde Mainline Model 2 became the B class in Victoria. The B class were the first mainline diesel-electric locomotives in Victoria entering service in June 1952. They were initially used on the main passenger and freight services, before moving out to other areas. They remained in service until the early 1990s.fiction This collection of Diesel Locomotive Manuals was published by the Clyde Engineeringclyde engineering, diesel locomotives, locomotives victoria

A collection of Locomotive operation manuals. All are paperback and feature an image of the relevant locomotive on the cover. Relevant illustrations are included in each publication. Cover is of card and they are bound with staples.fictionThe manuals refer to the following locomotives:- Westrail L Class (November 1983) originally built by Clyde Engineering from 1967 for the Western Australian Government Railways (WAGR) for use on the Eastern Goldfields Railway between Perth and Kalgoorlie. In 1983, three were leased to V/Line to haul services on the standard gauge Melbourne to Albury line, sometimes extending through to Sydney.A class (January 1984) were initially used for "Intercity" passenger services within Victoria. In this service, they operated at speeds up towards 125 km/h. Later, they were also used for freight services.N class (September 1985) produced by Clyde Engineering and entered service in 1985 and still operating in 2023. 422 Class diesel-electric locomotives (August 1983), designed by Clyde Engineering were introduced in January 1969. Following crew training, the engines entered service on the Main Southern line between Sydney and Albury and the Illawarra line from Sydney to Port Kembla and Moss Vale. Among the passenger services they hauled were the Southern Aurora and the Spirit of Progress. From 1982, they began to operate through to Melbourne. This ceased in February 1990 when non-air-conditioned locomotives would no longer be accepted by Victorian drivers.railways victoria, diesel-electric locomotives
