Metal surgical instrument. Consists of scissor like handles with circular finger grips atop two metal arms. There is a metal gauge extending between the handles approximately an inch below the finger grips which provides a measurement as to how far apart the tips of the instrument are at any given time. A curved metal plate is attached between the handles below the gauge which functions as a spring to give some resistance to the instrument. The arms are joined together by a pin at the centre. Metal plates attached to the underside of the lower part of the arms lock into place as the instrument is opened. Each arm narrows in the last two inches and ends in a round point, with the end points resembling the nose of a pair of pliers. The words 'MEDICAL SUPPLY DEPOT' are engraved on one arm of the instrument. The number '18' is engraved on the inside of both arms towards the tip.'MEDICAL SUPPLY DEPOT', '18'gynaecology

This set of calipers was used for measuring and marking in the planning and making of components for the ship model Sovereign of the Seas. It is part of a collection of objects used by Jim Williams, maker of fine ship models from about 1930-1955. Most of the components for the models, as well as many of the tools, were handmade by Jim Williams. Jim’s family has donated the ship model “Sovereign of the Seas” and many tools, accessories and documents used in the making of this and other ship models have been donated to Flagstaff Hill Maritime Village. Ship model of HMS Sovereign of the Seas, scale model of 17th Century English war ship, was handmade and carved from plans, enclosed in airtight glass case. All components of that model, including even the smallest pulleys, were hand crafted using tools designed and made by Jim. Outstanding details include functional rigging and moving cannons. Please see our record 3732 of the mode Sovereign of the Seas for further details of the ship and the maker. This calliper is connected with the hobby and skill of ship model making that has been crafted as a leisure activity for many generations. The hobby is often chosen by serving and retired mariners who appreciate the connection with maritime history. This calliper was used by local Warrnambool man, Jim Williams, who was employed at Cramond and Dickson clothing store, and then at Fletcher Jones menswear for 27 years. It was used in making components for the model of the historic ship, the Sovereign of the Seas. The Sovereign of the Seas was a historic 17th century English war ship with important maritime heritage. Calipers, metal, two arms joined by hexagonal bolt.

In 1885 Julius Pitrat of Gallipolis, Ohio, patented the first computing scale. Six years later, Edward Canby and Orange Ozias of Dayton, Ohio, purchased Pitrat's patents and incorporated The Computing Scale Company as the world's first computing scale vendor. And four years after that, The Computing Scale Company introduced the first automatic computing scale In 1911. the Computing Scale Company merged with the International Time Recording Company and Tabulating Machine Company to form the Computing-Tabulating-Recording Company, a business that was renamed IBM in 1924. An early example of a hanging clock face scale patented in October 1897 and made by a company that pioneered the first computing scales used in retail businesses. This company went on to become incorporated with IBM that late became an international computer manufacturer.Scale, patented Oct 12, 1897. Measures in pounds and ounces, up to 10lb.

An aneroid barometer is an instrument used for measuring air pressure as a method that does not involve liquid. Invented in 1844 by French scientist Lucien Vidi, the aneroid barometer uses a small, flexible metal box called an aneroid cell (capsule), which is made from an alloy of beryllium and copper. The evacuated capsule (or usually several capsules, stacked to add up their movements) is prevented from collapsing by a strong spring. Small changes in external air pressure cause the cell to expand or contract. This expansion and contraction drives mechanical levers such that the tiny movements of the capsule are amplified and displayed on the face of the aneroid barometer. Many models include a manually set needle which is used to mark the current measurement so a change can be seen. This type of barometer is common in homes and in recreational boats. It is also used in meteorology, mostly in barographs and as a pressure instrument in radiosondes.5 inch Aneroid barometer on wooden basebarometer, aneroid

In 1902, William E Sessions and other family members purchased a controlling interest in the E.N. Welch Company, a clock manufacturer located in Forestville, Connecticut. Sessions' father owned a foundry located in the town of Bristol, Connecticut that produced cases for E.N Welch Co. On January 9, 1903, the company was reorganized and registered as The “Sessions Clock Company”. Within a few years the Sessions Clock Company was producing clock movements, cases, dials, artwork and castings for their line of mechanical clocks. Between 1903 and 1933 Sessions produced 52 models of mechanical clocks, ranging from Advertisers, large and small clocks with logos of various businesses, to wall, or regulator clocks, and shelf or mantel clocks, designed for the home. Many of the Session clocks from this period are prized by collectors. In 1930, the company expanded to produce electric clocks and timers for radios, while continuing to produce traditional brass mechanical movements. Beginning at the end of World War II Sessions W Model (electric) was widely used by various casting companies for their clocks. The dial of the W Model read Movement by Sessions. In the early 1950s Sessions begin to produce timers for television. In 1956, Sessions was absorbed by a company interested mainly in their timing devices. In 1959, William K. Sessions, grandson of William E. Sessions left the Sessions Clock Company and formed the New England Clock Company. In 1960, one of the Sessions Clock buildings was sold to the Bristol Instrument Gears Company. Kept as the Sessions Company, the new owners ran the operation until 1969 when changes in the market forced the Sessions Company into liquidation. In 1970, the remaining buildings were sold to Dabko Industries, a machine parts manufacturer.The item marks a time when clock production in America was at it’s peak producing clocks for sale in many countries, they were keenly priced, mass produced and available to all. The company had a relatively short life span life regards clock manufacture later diversifying into electric timer mechanisms. Yet it was perhaps inevitable with the advent of electricity along with stiff competition from other clock manufactures that would ultimately herald the end in 1935 of the Sessions company's ability to continue manufacturing mechanical clocks.

A fob watch is an instrument for measuring time. It is designed to hang from a chain that is attached to a wearer's waistband or waistcoat. The chain keeps the fob watch from being dropped or falling out of a pocket. A person possessing a fob watch or similar instrument in the 18th century would be viewed as someone in a good financial position and often a position of power or respect. It was a social statement as well as a useful object.Silver pocket watch and brass iron winder. Watch has Roman numerals on face and gold flower, floral and diamond shaped motif. Marked "0.800 x/5 115/15 39443" Picture of a bird, flying, griping a painter's pallet and brushes and another separate picture of a bird. There is also a floral pattern on the back of the watch.

William Thomson described a new "Marine Azimuth Mirror" at the 1877 meeting of the British Association for the Advancement of Science, and patented the design in Britain and the U.S. This instrument is an example of the improved design, with a reflecting prism in place of the original mirror. Thomson introduced this form in the early 1880s. The signature indicates that it was made during the period 1900-1913. A child prodigy, William Thomson went to university at the age of eleven. At twenty-two he was appointed Professor of Natural Philosophy in Glasgow where he set up the first physics laboratory in Great Britain and proved an inspiring teacher. He primarily researched thermodynamics and electricity. On the practical side he was involved in the laying of the Atlantic telegraph cable. He was also the partner of a Glasgow firm that made measuring instruments from his own patents.An instrument of significant importance which made marine navigation easier and more accurate in the early twentieth century.An Azimuth mirror with wooden box.Kelvin & Hughs Ltd Serial No - illegible Made in Great Britainazimuth mirror, william thompson, lord kelvin, naviagtion, marine instruments

William Jackson Thomas is credited with making the first ever telephone call in Victoria. Thomas was a customs inspector at the Geelong Customs House and a keen amateur scientist, astronomer and woodworker. He experimented with electricity and induction to develop his own telephone soon after its invention by Alexander Graham Bell. He built most of the experimental telephone equipment himself – right down to the screws. According to the Geelong Advertiser, on 27 December 1877, Thomas held a telephone conversation with friends in a summer house 40 metres away.This instrument is of great historic significance as the instrument which made Australia's first telephone call in 1877, between two houses in Geelong. Although predated by Alexander Graham Bell's invention, this instrument is an example of Australian innovation and design; characteristic of Australian communications history. The instrument has excellent provenance, carrying a descriptive plaque about the use of the item. As an early prototype of a telephone, it is an incredibly rare example of communications technology.Stained wooden rectangular box containing mechanism with circular turned section at one end being the receiver and transmitter.

This representative example demonstrates a mariner’s astrolabe. Historical examples are rare. There are less than one hundred known to exist and most of these have been recovered from shipwrecks, many from Spanish and Portuguese vessels. An astrolabe is a measuring device once used to navigate the seas by observing the sun and stars to measure their altitude. The measurement of altitude could then be used to calculate the ship’s latitude but at that time in history there was no means of measuring longitude. The body of the navigational astrolabe was cast brass and much heavier, and less complicated than the variety used on land. The heavier weight and cut-away shape reduced the effect of the wind and waves when trying to use it at sea. A mariner’s astrolabe or ‘star finder’ is a simplified version than that used by Arabic astronomers to find the altitude of the sun and stars above the horizon, and time of the sunrise and sunset. It is a forerunner to the quadrant, octant and sextant and was popular for about 200 years over the 1500s and 1600s to find the latitude of a ship at sea. The user held the astrolabe at eye level and, usually with assistance, aligned the stars through the two small sights (pinnules), then read the altitude indicated by the pointer on the arm. It could also be used to sight the sun by holding it lower down, aiming it at the sun, and adjusting it until the sun shone through both pinnules. This astrolabe is an example used to demonstrate the mariner’s astrolabe, which was navigational tool of the 1500s and 1600s, in the time before longitude was able to be determined. It is a forerunner to modern navigation technology. Mariner’s astrolabe – a representative example. A gold painted, disc shaped object with cut outs and revolving arm in centre.

The sphygmomanometer is an early diagnostic instrument used to measure blood pressure. Since the discovery of blood circulation in 1628, the search for accurate, convenient, simple, and non-invasive tools has led to evolving measuring devices and cuffs. Until the twentieth century, few doctors tolerated the inconvenience of blood pressure measurers and relegated the exiting tools to laboratory research. The mercury and later aneroid sphygmomanometers provided the accuracy and portability required for clinical use.The sphygmomanometer is an early diagnostic instrument used to measure blood pressure.

Formerly of Station Works, Wakering Road, Barking, Essex, Henry Browne & Son were important British compass makers. The company was founded in the nineteenth century in Barking and London. They were respected English instrument makers who made fine quality compasses, ships clocks, inclinometers, sextants and chandlery items for over 140 years. Their "Dead Beat" compass, which was well dampened to reduce oscillation, was fitted to many Allied ships during the Second World War. Sestrel was their famous Trade Mark brand. The company was sold to John Lilley & Gillie Ltd and SIRS Navigation, both UK companies, in 1993.
