Scales, Imperial, Spring, 'Salter Household Scale’ 28lb, c1920
In the 18th century, spring scales appeared. To produce these scales, a manufacturer would use the resistance of a spring to calculate weights, which could be read automatically on the scale’s face. The ease of use of spring scales over balance scales is what led most post offices to outfit their clerks with spring postal scales. One of the most common types of spring scales was the kitchen scale—also known as a family or dial scale. Designed for horizontal surfaces, these scales used the weight of goods in a pan at the top of the scale to force the spring down. Such scales were common in early-20th-century households and were sold by Sears and Montgomery Ward. Many had flat weighing surfaces but some were topped by shallow pans. Companies such as Salters, Chatillon, and Fairbanks made both. SALTER HOUSEWARES began in the late 1760 in the village of Bilston, England. At this time Richard Salter, a spring maker, began making 'pocket steelyards', a scale similar to the fisherman's scale of today. By 1825 his nephew George had taken over the company, which became known as George Salter & Co. and later established a large, well equipped manufacturing site in the town of West Bromwich. The business thrived throughout the 1900s, and in 1972 the company was purchased by Staveley Industries Plc. In 2002, the management team at Salter Housewares Ltd, backed by Barclays Private Equity, bought the company out from the group, to concentrate on its consumer businesses.

Equipment - Spring Balance Scale, George Salter & Co, 1920s
Scales such as the subject item were used to measure commercial quantities, possibly grains and farm produce for quite large amounts of product. Bags of grain etc would have been hooked up and weighed. Salter has been a name long associated with weights and measures. The firm began life in the late 1760s in the village of Bilston, England when Richard Salter, a spring maker, began making the first spring scales in Britain. He called these scales "pocket steelyards", though they work on a different principle from steelyard balances. By 1825 his nephew George had taken over the company, which became known as George Salter & Co. George later established a manufacturing site in the town of West Bromwich, about 4 miles (7 km) from Bilston. West Bromwich Albion football club was formed from workers at this works site. From here the company produced a wide variety of scales including the UK's first bathroom scales. Other items were added to the range, including irons, mincers, potato chippers, coin-operated machines and the first typewriters made in the UK. The business thrived throughout the 1900s, and by 1950 it employed over 2000 people, still in the same area and owned by the same family.Salter is a British housewares brand developing products that span a wide range of core product categories, including scales, electrical, cookware. It is a market leader in kitchen and bathroom scales and one of the UK’s oldest consumer brands. Established in 1760, Salter has been developing precision products for over 260 years.

Machine - Fusee Clock Mechanism, early 20th Century
The origin of the fusee is not known. Many sources credit clockmaker Jacob Zech of Prague with inventing it around 1525. The earliest dated fusee clock was made by Zech in 1525, but the fusee appeared earlier, with the first spring-driven clocks in the 15th century. The idea probably did not originate with clockmakers, since the earliest known example is in a crossbow windlass shown in a 1405 military manuscript. Drawings from the 15th century by Filippo Brunelleschi and Leonardo da Vinci also show fusee mechanisms. The earliest existing clock with a fusee, also the earliest spring-powered clock, is the Burgunderuhr (Burgundy clock), a chamber clock whose iconography suggests that it was made for Phillipe the Good, Duke of Burgundy about 1430. Springs were first employed to power clocks in the 15th century, to make them smaller and portable.[1][5] These early spring-driven clocks were much less accurate than weight-driven clocks. Unlike a weight on a cord, which exerts a constant force to turn the clock's wheels, the force a spring exerts diminishes as the spring unwinds. The primitive verge and foliot timekeeping mechanism, used in all early clocks, was sensitive to changes in drive force. So early spring-driven clocks slowed down over their running period as the mainspring unwound. This problem is called lack of isochronism. Two solutions to this problem appeared with the first spring-driven clocks; the stack freed and the fusee. The stack freed, a crude cam compensator, added a lot of friction and was abandoned after less than a century. The fusee was a much more lasting idea. As the movement ran, the tapering shape of the fusee pulley continuously changed the mechanical advantage of the pull from the mainspring, compensating for the diminishing spring force. Clockmakers empirically discovered the correct shape for the fusee, which is not a simple cone but a hyperboloid. The first fusees were long and slender, but later ones have a squatter compact shape. Fusees became the standard method of getting constant force from a mainspring, used in most spring-wound clocks, and watches when they appeared in the 17th century. Around 1726 John Harrison added the maintaining power spring to the fusee to keep marine chronometers running during winding, and this was generally adopted. The fusee was a good mainspring compensator, but it was also expensive, difficult to adjust, and had other disadvantages: It was bulky and tall and made pocket watches unfashionably thick. If the mainspring broke and had to be replaced, a frequent occurrence with early mainsprings, the fusee had to be readjusted to the new spring. If the fusee chain broke, the force of the mainspring sent the end whipping about the inside of the clock, causing damage. The invention of the pendulum and the balance spring in the mid-17th century made clocks and watches much more isochronous, by making the timekeeping element a harmonic oscillator, with a natural "beat" resistant to change. The pendulum clock with an anchor escapement, invented in 1670, was sufficiently independent of drive force so that only a few had fusees. In pocketwatches, the verge escapement, which required a fusee, was gradually replaced by escapements which were less sensitive to changes in mainspring force: the cylinder and later the lever escapement. In 1760, Jean-Antoine Lépine dispensed with the fusee, inventing a going barrel to power the watch gear train directly. This contained a very long mainspring, of which only a few turns were used to power the watch. Accordingly, only a part of the mainspring's 'torque curve' was used, where the torque was approximately constant. In the 1780s, pursuing thinner watches, French watchmakers adopted the going barrel with the cylinder escapement. By 1850, the Swiss and American watchmaking industries employed the going barrel exclusively, aided by new methods of adjusting the balance spring so that it was isochronous. England continued to make the bulkier full plate fusee watches until about 1900. They were inexpensive models sold to the lower classes and were derisively called "turnips". After this, the only remaining use for the fusee was in marine chronometers, where the highest precision was needed, and bulk was less of a disadvantage until they became obsolete in the 1970s. Item is an example of clock mechanisms used until 1910 for many different styles of clocks and went out of fashion in the 1970s due to improvements in clock and watch making.Brass fusse clock movement, It has very heavy brass plates and wheels, high-count machined pinions, and a fusee. The mounting of the pendulum is missing and It has a recoil escapement. A fusee is a conical pulley driven through a chain by the spring barrel. As the spring runs down, the chain acts at a larger and larger radius on the conical pulley, equalising the driving torque. This keeps the rate of the clock more even over the whole run. It has motion work to drive an hour hand as well as a minute hand and the centre arbor is extended behind the back plate to drive some other mechanism.Inscription scratched on back"AM 40" flagstaff hill, warrnambool, shipwrecked-coast, flagstaff-hill, flagstaff-hill-maritime-museum, maritime-museum, shipwreck-coast, flagstaff-hill-maritime-village, clock mechanism, fusee mechanism, horology -
