Instrument - Hydrometer, 1878 to 1930s
... pressure measurement... Shipwreck Coast Sikes Hydrometer Scientific Instrument pressure ...This Sikes brass hydrometer was manufactured by the optical and scientific instrument makers Kasner & Moss of 17 Collins Street West, Melbourne, in the latter part of the nineteenth century. The firm adverted hydrometers, as well as optical instruments, as early as August 13th, 1864, in The Age, Melbourne. This hydrometer set was donated to Flagstaff Hill in 1979 by local wine and spirits merchants Lynch Bros of Fairy Street, Warrnambool. Giffen Russell had established the business in 1878, and Harry Lynch took it over in the 1930s, and after he passed away in 1953 Kevin Matthew Lynch became proprietor of K M Lynch Food and Liquor. The business closed in the 2010s. The hydrometer may date back to the establishment of the business in 1878, as Kasner & Moss were selling hydrometers in Melbourne from 1864. 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. This hydrometer and its fitted and hinged wooden container show signs of heavy and protracted use in a working environment. Although the instrument has some parts missing and has been recently repaired, the original quality of the inlaid box and the fine engraving on the instrument and the attachable weights, are indications of the hydrometer’s very real value when new. This Sikes hydrometer, bearing the maker's mark of “Kasner & Moss Melbourne” and the registered number “20373”, was presented to the purchasing public as a precision-made instrument designed for professional use. The Sikes hydrometer is of local significance because of its implied association with the alcohol trade in the southwest region of Victoria. It was donated by a family member of Lynch Bros, a local licensed outlet for wines and spirits in the period before the general relaxation of liquor licensing laws in the State of Victoria. It may have belonged to Griffin Russell who established the liquor store in 1878.Hydrometer; original Sikes brass hydrometer in a polished wooden case with an inlaid plaque on the lid. The brass float is a sphere with a thin flat upper stem and a short, lower stem with a bulb-shaped end. The upper stem is engraved scale on both sides with the numbers 1 to 10, and five divisions between each number. There are ten fixed pegs in the base to secure the thick brass horseshoe-shaped, numbered, various-sized weights (20, 30, 40, 80, 90); the free pegs would have originally stored another five weights (10, 50, 60, 70, and 100). The empty compartment in the box suggests another part in the initial set, probably a thermometer. The fitted, fabric-lined box has two brass closures and two brass hinges. The scientific instrument shows signs of heavy use and repairs. The Serial Number on the float matches the Serial Numbers on the weights. The plaque on the lid, the float and the weights have inscriptions. Made by Kasner & Moss, Melbourne. Plaque: “SIKES HYDROMETER / KASNER & MOSS / MELBOURNE” On float's lower stem: “SIKES 20373” On one thin edge of the float's scale, engraved in script “Kasner & Moss” and stamped “MELBOURNE”, and symbol“P” rotated 90 degrees.

... pressure measurement... Scientific Instrument pressure measurement measuring instrument ...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.

... . Harvey Cushing Blood pressure Measurement Anaesthetics John Marum ...In the 1600s, William Harvey realised a finite amount of blood circulates in one direction through the body. Jean Léonard Marie Poiseuille introduced the mercury hydrodynometer in the early 1800s for measuring blood pressure. Karl von-Vierordt created the sphygmograph in 1855 and, in 1881, Samuel von Basch created the sphygmomanometer, distinct improvements on the hydrodynometer. In 1896, Scipione Riva-Rocci developed the mercury sphygmomanometer. American neurosurgeon, Harvey Cushing, was an early adopter, and advocate for monitoring patients during surgery and anaesthesia. Blood pressure monitoring is still an essential component of evaluating a patient’s condition.This blood pressure kit is housed in a rectangular, vinyl covered box with metal handle and press-stud lid release mechanism. The lid opens upwards and the glass blood pressure valve and plastic scale is attached to the underside of the lid. The measurements are written in black and go up in increments of ten, from 0 to 300. The glass valve has unidentified increments labelled in red, which is housed within a metal cylinder. The bellows is attached to the measuring valve via a dark green pressure cuff and rubber hose.Blue sticker affixed inside the kit: JOHN MARUM Ornate manufacturer's label: THE ARMOURED / ELLISCO / SPHYGMOMANOMETER / MADE BY / ELLIOTTS & AUSTRALIA DRUG / [indecipherable] LTD / CENTEN[indecipherable] MODELharvey cushing, blood pressure, measurement, anaesthetics, john marum, sphygmomanometer, elliotts & australian drug pty ltd, centenary model, cuff, bellows, ellisco, armoured -

Photograph - Johnson Ground Elevation Meter (JGEM) Survey Vehicle - Army Survey Regiment, Fortuna, Bendigo, c1960s
This is a set of 16 photograph of the Royal Australian Survey Corps’ Johnson Ground Elevation Meter (JGEM) Survey Vehicle taken at the Army Survey Regiment, Fortuna, Bendigo. The JGEM vehicle was extensively used by RA Svy within Australia from the late 1960s. A limited number of Ground Elevation Meter (GEM) station wagon type vehicles were manufactured by General Motors Corporation (GMC) in the USA for the United States Geological Survey, Canada’s mapping agencies, RA Svy and National Mapping (Natmap). The GEM was a four-wheel drive, four-wheel steer vehicle. Four-wheel steering was necessary to avoid systematic errors caused by non-tracking of front and rear wheels on conventionally steered vehicles. The manufacturer substituted the rear axle with a front axle and connected them to form the four-wheel steering mechanism. The two Australian GEM vehicles, referred to as Johnson GEMs (JGEMs) were converted into right-hand drive. After delivery in 1964, acceptance Natmap and RA Svy testing and operator training was undertaken at the Army's School of Military Survey located at Balcombe, Victoria. A small fifth wheel was mounted on a cantilever arm suspension midway between the front and rear wheels on the right side of the vehicle. It was lowered to and raised from its operating position by use of a constant pressure air cylinder. A telescopic bar, suspended between the front and rear axles, provided the reference datum for the angle measurement. The wheel provided the velocity or distance signal through a pulse generator system. A sensitive pendulum mounted on this bar provided the angle measurement for each minute distance traversed. The JGEM contained electromechanical instruments used to determine relative elevations, by trigonometric principles, along a traversed path. These relative elevations were obtained through apparatus which measures the instantaneous angle of inclination of the road and the instantaneous velocity of the meter along such a path. Road routes over which the JGEM operated were planned so that each started and ended as near as practicable to an existing point of known elevation (formally referred to as a level traverse bench mark). The difference in height from the bench mark and the road surface alongside the JGEM’s fifth wheel was measured with a level and staff. Along each route, mapping control photo reference points where new elevation values were required were identified on aerial photographs. Under favourable conditions it was possible to survey as much as 160km in an ordinary working day. The first of RA Svy’s JGEM operations was undertaken in 1:250,000 scale map areas of Queensland. CPL John Hook was the JGEM’s main operator in the early 1970s undertaking operations covering 1:250,000 scale map blocks over northern Victoria and central NSW, each requiring 36 points (9 runs of photography and 4 points across. SPR Lyn Thompson and SPR Bob McDonagh teamed with CPL Hook on some of these JGEM operations. When RA Svy was integrated into the Royal Australian Engineers in 1996, the JGEM vehicle with the Survey Corps collection was donated to its museum. It is believed to be the last of the original manufactured fleet in existence. The JGEM has undergone extensive refurbishment to achieve roadworthiness and is currently housed at The Australian Army Museum of Military Engineering, Hoslworthy Barracks, NSW. It can be viewed by making an appointment with the museum’s curator.This is a set of 16 photograph of the Royal Australian Survey Corps’ Johnson Ground Elevation Meter (JGEM) Survey Vehicle taken at the Army Survey Regiment, Fortuna, Bendigo.

Instrument - Scale, George Salter & Co, Circa 1921
The Hughes’ Family Scale No. 48 is a spring balance scale. It uses the Imperial measurements of ounces and pounds. There are 16 ounces (OZ) in one pound (LB), and each pound equals approximately 454 grams in Metric measurements. Scales have been used to measure and compare items for value for centuries. A weight was placed on one side of a balance and the object was placed on the other. Adjustments were made to either the weight or the object until the balance was horizontal, which meant that each side was the same weight. The Salter family business began in 1760 with spring makers, Richard and William Salter. In the late 18th century, Richard Salter invented the spring scale, where the weight of an object on the tray of the scale causes pressure on a spring in the scale. The pressure caused by gravity was then measured to calculate the weight of an object. Spring scales are still used today along with the more recent and accurate digital scales. The company began manufacturing in West Bromwich, England, in 1770. The firm was taken over by William’s sons, John and George. In 1824, after the death of John, the firm became George Salter & Co. The company produced a wide variety of products, including Britain’s first bathroom scale and the first English typewriter. In 1884 the Salter Trademark of a Staffordshire knot pierced by an arrow was registered. After over 100 years of manufacturing, the company was bought out by Staveley Industries, which was bought by Weigh-Tronix, and then that company was bought by HoMedics Company in 2004.This scale was made by Salter, the company that invented the balance scale, the first British bathroom scale and the first English typewriter. The scale represents the domestic equipment used for measuring in food preparation over 100 years ago. Modern kitchen scales are still using the same principal, along with scales used in business and industry.Scale; a domestic spring balance scale for measuring weight from 0 to 20 pounds. The scale’s grey metal case has a round white dial on the front with black markings, an arrow indicator and a round shallow metal bowl on a pedestal at the top. The scale is raised on a rectangular metal base with outward-sloping sides. An adjustable screw is on the dome top. The scale is marked from 0 to 20 pounds, with each pound marked in 1-ounce increments. The scale is named the Hughes Family Scale No. 48 and was made in Britain by Salter.“HUGHES’ / FAMILY SCALE / No. 48” “BRITISH MADE” “TO WEIGH 20 LBS BY 1 OZ” “SALTER” above logo [knotted rope with an arrow through loops]flagstaff hill, warrnambool, maritime museum, maritime village, great ocean road, shipwreck coast, hughes, salter, british made, family scale, no. 48, spring balance, scale, weighing instrument, weights and measures, weighing machine, kitchen utensil, baking accessory, domestic equipment, cookware, bakeware, kitchen scale, kitchen accessory, food preparation, recipes, cooking, measuring -

Instrument - Aneroid Barometer
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 -

Surveyor's Pocket Altimeter, c 1940
This instrument measures elevation by sensing minute changes in barometric air pressure relative to a fixed datum point at sea level or a known elevation, such as the starting point of a major town during a road survey, and has an accuracy of +/- 20 feet when used in experienced hands. The finely divided scale around the perimeter of the face is marked from 0 to 6000 feet elevation and 25 to 31 inches of mercury (Hg) for barometric pressure The single fine counter-balanced hand or pointer rotates anti-clockwise with increasing elevation and decreasing pressure. The label "compensated" indicates that the instrument is constructed to compensate for the effect of temperature changes on the accuracy of readings.
