Instrument - Scale, George Salter & Co, Circa 1921
... scale weighing instrument weights and measures weighing machine ...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 - Letter Scale, Ca. early 20th century
... Collection scale weighing instrument measure weight postal scale ...This handheld portable pendulum quadrant scale was used to weigh small paper items such as letters and documents, powdered chemicals or metals like gold, and animal fleece samples. This mechanical scale can weigh up to a maximum of 10 ounces, which is about 285 grams or one-and-a-half cups of brown sugar. The operator holds the scale’s ring and connects the item to be weighed onto the wire clip. The weight of the item causes the pendulum to pivot, and the scale measures the weight of the object, indicated by the arrow. This scale belonged to Dr William Roy Angus and is now part of Flagstaff Hill’s comprehensive W.R. Angus Collection, donated by the family of Dr W R Angus, 1901-1970, surgeon and oculist. The W.R. Angus Collection: - The W.R.

Instrument - Scale, George Salter & Co, ca. 1886
... weighing instrument mechanical scale hanging scale Stamped ...There were at least three 1880s vessels named Lady Loch, all built in Victoria; a river launch (ca 1884-ca 1916, originally named Lady of the Lake), a steamer ferry (1884-1920s) and a government lighthouse tender steamer HMV Lady Loch (1886-1962.) The spring balance scale was part of the equipment on the HMV Lady Loch. The scale was made by the renowned company Salter Weighing Machines in the United Kingdom. It was made to Silvester's patent design. Salter Weighing Machines, Britain, began making spring scales in the 1820s. In 1908 Salter opened up an Australian branch named Salter Scales Pty. Ltd. The scale, marked HMV SS Lady Loch, would be suspended by its top ring, a basket or other container is hung from the hook, and the items inside the basket then pull downwards on the hook, which stretches the springs inside the works. The pulling action moves a rack and gears a calculated distance and the gears turn the pointer on the dial to indicate the weight of the goods. This scale measures up to 200 pounds capacity. The HMV SS Lady Loch was an iron steamship built in Footscray, Melbourne, by Campbell, Sloss and McCain in 1886 for the colonial Victorian government’s Department of Trade and Customs. It was armed with a 6-inch gun and two 1-inch Nordenfelt guns. The Sydney Morning Herald of 27th January 1888 describes the vessel in detail. It even comments on the interior of the Saloon “The wood work … is on a very elaborate scale and is exceedingly neat …”. The HMV Lady Loch performed Customs duties, and serviced the lighthouses along the coast. The scale could have measured goods for the Customs Tax, or for measuring out supplies for the lighthouse keepers. The vessel was named after Lady Elizabeth Loch, wife of Sir Henry Loch, Governor of Victoria from 1884 to 1889. In 1932 Lady Loch was converted to a hulk and used in Brisbane, and finally scuttled in 1962 at Moreton Bay, Queensland.The scale has importance due to its connection to the 1886 HMV Lady Loch, a vessel of great significance to Melbourne’s shipbuilding industry. It was the largest auxiliary vessel in the Victorian Colonial Government’s fleet and the first prominent vessel launched by Melbourne’s shipbuilding industry. The scale is also important for its connection with the colonial navy's Custom's work, as the scale was available to weigh goods that could attract taxes and deal out goods for distribution to lighthouse keepers. The HMV Lady Loch was also important part of Victoria's maritime history for its communication and support of the lighthouse keeper's along the coast of Victoria.Scale; Salter's spring balance mechanical hanging scale, brass and iron. Equally spaced marks around the circular dial have values from 0 to 200 in increments of 10, each increment is also divided into 10. An iron ring is attached to a fitted loop on the top of the scale, and an iron hook is attached to the fitted loop onthe bottom of the scale. A moving pointer attached to the centre of the dial has a calibration screw joined to its base. Four screws fix the brass face to the works at the back. There are stamped and embossed inscriptions. Made by Salter in Britain, to Silvester's Patent design. The scale was once equipment carried abourd the steamship HMV SS Lady Loch.
