Measurement of the circumference or diameter of a log was essential for determining the log's volume for the purposes of paying falling and carting contractors and for royalty calculations. The rugged Lufkin diameter tape was in widespread use in the Forests Commission. The tape was so calibrated as to enable a direct reading of a log's diameter when the tape was run around its circumference. The direct measurement side of the tape is marked in feet and tenths of feet (rather than inches) while the diameter-calibrated side is marked in inches and tenths of inches. diameter tapeOn the casing: THE LUFKIN RULE CO.

E. R. Watts and Son, makers of theodolites and other surveying instruments, of 123 Camberwell Road, London. The company was established in 1856 by Edwin Watts at twenty-three he had saved £100 from his earnings to start the business with his staff consisting of one boy and later Alexander Clarkson as an apprentice with the workshop a small room over a Bemondsey stable. Watts' first order was from Negretti and Zambra for a mining dial Alexander Clarkson In the early days the firm worked mainly on marine compasses. Edwin Watts would go down to the Docks to adjust the compasses once they had been installed on the ships. In May 1873 the business moved to larger premises a house with a garden. The workshop was also the home of Mr and Mrs Watts and their five sons and three daughters. By now there were fifteen to twenty men employed by the firm. The company were commissioned to supply the Theodolites and Levels for the construction to the Canadian Pacific Railway in 1881. Towards the end of the century, the firm began to make heliographs continuing to produce them for the government until just before the Second World War when by agreement assigned their manufacture to another firm. 1904 The first dividing engine was completed by George William Watts. It was so remarkable an instrument at the time and for years afterwards, In 1907 Arthur Ames went to Canada and started an organisation in Winnipeg in 1909 this became a separate company called E. R. Watts and Son Ltd. of Ottawa. This firm developed considerably and was eventually with the co-operation of three other instrument companies (Cambridge Instrument Co, Ross, and Negretti and Zambra), were reconstituted as ”Instruments Ltd” of Ottawa and Toronto. During the next ten years, the firm expanded greatly to include glass grinding, leather work, dividing and engraving, testing, adjusting and packing. This expansion was continued during the First World War when workshops were completed and the machinery installed and running within eleven weeks from the start of construction. During the war, a Sergeant Coles, among the rats, lice and mud of the trenches, fitted various bits of scrap into his cocoa tin and made the first Flash Spotter for plotting the positions of enemy guns. Coles was rushed home to the firm's factory where he and George William Watts designed a spotter not made out of a cocoa tin and as a result, the Watts Vertical Force Variometer was developed during WWI. Other Watts instruments made in the First World War included the Light Mountain Theodolites which were taken on Mt Everest expeditions. In 1919 ER Watts and Sons was incorporated as a limited company and in 1939 G. A. Whipple joined the Board of Directors. Shortly afterwards, Frank Charles Watts died having been Chairman of the firm for over 37 years and seen it through the First World War with all its expansions and difficulties. He was succeeded by his brother George William Watts with the vacant post of Managing Director being filled by G. A. Whipple. During the Second World War, the company expanded further and the number of employees rose to well over 1,300. In 1946 Watts acquired 78% of Adam Hilger and the microscope maker James Swift and Son Who were Manufacturers of Theodolites, Levels, Alidades, Meteorological Instruments, Variometers, and many other types of scientific instruments Then in 1948 the company amalgamated with Adam Hilger as Hilger and Watts which was then incorporated as a public company.Naval Rangefinder with a vertical wooden handle, and an arrangement of optical lenses.

This Sike’s Hydrometer was donated by the Port Fairy Customs Office as it was no longer required by them due to a change in the law. The hydrometer was part of a system for Ullaging or calculating the amount of liquid remaining in a container of liquor such as a barrel, and the amount of alcoholic content in the contents. It can also measure the free space or head space remaining. Hydrometers were used to measure the density, or relative density, of liquids from the late 1600s. In 1816 Bartholomew Sikes won the competition for the most useful accurate hydrometer. Hydrometers were commonly used by distillers, vintners, and brewers to establish accurate measures of alcohol concentration in their beverages. Following this manufacturing process, government inspectors and excise officers used them to check that the labelled indications of alcohol-proof were correct and that the right amounts of duty were being paid.The Sikes hydrometer is of local significance because of its association with the Government's Customs Office in Port Fairy, in the southwest region of Victoria. It is also associated with Bartholomew Sikes, whose design of a hydrometer was chosen in 1816 as being the most useful and accurate hydrometer. The hydrometer has evolved into the digital version available today to measure density of liquids.Sikes Hydrometer and thermometer in a fitted wooden case with crimson lining inside the lid and dark lining in the base.

A pelvimeter is used in obstetrics for measurement of the female pelvis, with the aim of attempting to determine whether there will be any potential issues with a vaginal birth. This pelvimeter is similar in style to Martin's pelvimeter (see Aesculapius). This instrument was included with other obstetric instruments, mostly destructive instruments, given to RANZCOG from Box Hill Hospital labour ward in February- March 1998. The maternity service at Box Hill Hospital combined with St Geroge's Hospital in Kew to be known as Birralee Maternity Service. These instruments were collected by Julie Collette, Unit Manager, St George's Kew and given to RANZCOG Museum Curator, Susan Barnett.Pelvimeter, manufactured by Ramsay.

This resistor was part of the Hydro generator control metering system which displays what electricity is produced at the underground generators. The control centre can be hundreds of meters above the generators and this resistor reduces the large current to a small voltage entering a calibrated control monitor. This resistor is highly significant to the Kiewa Valley because it represents a major construction and ongoing operational industry dealing with the supply of hydro electricity to Victoria. Although it is relatively small in size it is part of the controlling mechanism for the supply of a non polluting energy source for home and industrial use.This mainly metal and wire resistor has been built of copper and brass and designed to carry a current of 2000 Amperes. Wires are wound around a non conductive cement block which has grooves on the top and bottom ledges to hold the wires snuggle into place. At the rear there are three connection rods which have long 5mm thick screws (to fasten cable ends)On one side it is scribed "0.2 OHMS" and underneath this "10 AMPS"kiewa hydro electricity scheme, victorian state electricity commission, transformers

This Gestetner Cyclostyle duplicating machine was invented and manufactured by David Gestetner. He claimed in 1922, once he had released several models, that if a Gestetner Durotype stencil was used together with his Cyclostyle machine, then 10,000 copies could be made from the one Durotype stencil, an amazing claim for office technology of that era. David Gestetner (1854-1939), was born in Csoma, Hungary. He has been called the “founder of the worldwide office copying and duplicator industry.). He moved to London and in 1879 filed his first copying patent. In 1881 he patented the Cyclostyle stylus (or pen), which was used in conjunction with his Cyclograph device for copying text and images, He established the Gestetner Cyclograph Company in England at this time (1881) to protect his inventions and to produce his products; stencils, stylos (stylus or pen) and ink rollers. HIs inventions included nail-clipper and the ball-point pen (although the latter is more commonly associated with Laszlo Biro). Gestetner’s patented Cyclograph duplicator was used with his Cyclostyle Stylus or pen to write or draw on special thin wax-coated stencil paper (originally used for kite making paper) in the following way; 1. The Cyclostyle stencil was placed on a lower, framed metal plate of the Cyclograph 2. An upper frame was clipped over the top 3. The Cyclostyle pen, with its tip being a small metal-spiked or toothed wheel, was used to write or draw on the stencil, punched small holes into the paper and removed the wax coating in those places 4. The upper frame and stencil was then removed and a piece of blank paper was placed onto the metal plate in the lower frame and the upper frame with stencil was replaced 5. A roller was given an even distribution of Cyclostyle ink and rolled by hand over the stencil in the frame. This forced the ink through the holes in the stencil to and made a copy of the stencil on the paper 6. The upper frame was raised, the printed paper removed and another blank sheet was put into place. The whole process was repeated until enough copies were made. Gestetner’s invention developed further in 1894, with a stencil that could be placed on a screen on a revolving drum. The drum was manually rotated, the stencil then wrapped around another drum and was fed between cloth-covered rollers on which ink was evenly spread. Each revolution of the drum forced ink through the holes in the stencil and transferred the ink onto paper that had been fed between rollers and pressed against the drum. The process was repeated for each page. The paper was still fed and removed manually in this earlier invention but became more automatic in later models. In 1902 Gestetner duplicator model 6 was put onto the market. This model included the improvement of an automatic paper feed that synchronised with the rotation of the stencil. The Gestetner machine was the first office printing machine. It was easily installed and it made exact copies of the sane document quickly, effectively and inexpensively. This changed the way offices operated, making information easily available to many more users. The machines were commonly used in small businesses, schools, churches, clubs and other organisations for the wide distribution of a wide variety of information in the form of worksheets, newsletters and more. In 1906 the Gestetner Works were opened in Tottenham Hale, North London, and thousands of people were employed there up until the 1970’s. Due to the fast growing success of the Gestetner Duplicator machines many international branches for sales and service centres were established. David Gestetner was succeeded by his son Sigmund, followed by his grandson’s David and Jonathan. Further advancement was made by using a manual typewriter with specifically designed stencils. The end product was a printed, typewritten copy similar to the print from newspapers and booklets. In the next few years there were further developments of this revolutionary invention. The Gestetner Cyclostyle duplicator in our Collection is dated c.1922 - 1929 and it uses Gestetner Durotype stencils The 1922 British Industries Fair’s catalogue contained advertising for the Gestetner Rotary Cyclostyle “The World’s Premier Duplicator”, demonstrated at Stand K 86.” A Notice at the foot of the advertisement’s page boasts "Important - D Gestetner's latest invention, the "Durotype" Stencil, enables you to obtain 10,000 copies from one original if desired. It contains no wax of any description, is indestructible, can be stored indefinitely and printed from as required” In 1929 the look of the Gestetner machines changed; American designer Raymond Loewy was invited by Gestetner to improve the look of his duplicators, resulting in a very streamlined appearance. Eventually, around 1960’s, offices replaced their Gestetner with small photocopying machines and printers. Gestetner took over ownership of other office machine companies over time, including Nashua, Rex Rotary, Hanimex and Savin and eventually all came under the holding company name of NRG (Nashuatech, Rex Rotary and Gestetner). In 1996 Ricoh acquired the Gestetner Company, and it was renamed the NRG Group.
