The Crane foundry opened some time before 1827 and was known as Atherton’s Foundry, run by James Atherton and Henry Crane. Initially it was a brass foundry, but by 1827 iron castings were also produced on the site. The main products were castings for the building industry, ironmongery and brassware. In the 1830s castings for the hand tool and lock industries were added to the product range and by 1836 Henry Crane had taken control of the business. The company became known as the Crane Foundry in 1847 with its own registered trademark. By the 1850s iron weights were produced, and a design was registered in 1872 with roundels decorating the edge. Brass weights were also produced, mainly after the regulation of 1890 that required weights of 2oz. or less to be made of brass. In the early 1900s the foundry began to produce castings for electric motors and continued to do so throughout its life. The Crane family continued to control the company until 1917 when William Cyril Parkes of lock makers Josiah Parkes & Sons Limited, Willenhall became a majority shareholder. Things were going well until the company’s liabilities spiraled out of control with the rise in electricity and gas prices along with the loss of two of the company’s largest customers. The factory went into liquidation and then closed in 2006 an end to one of Wolverhampton’s oldest companies.An item made by one of England's foundry’s based in Wolverhampton that exported items all over the world for many years.

Information from Norman F. Dalton: Ballarat had a reticulated DC supply in the early part of last century and in 1905 had sufficient generating capacity to enable the trams to be changed from horse drawn to DC electricity. The use of electricity increased with the main power station located on Wendouree Parade, near Webster Street, under the ownership of The Electric Supply Company of Victoria. AC generating plant was installed in 1925 and conversion to AC proceeded. In 1934 the company was taken over by the State Electricity Commission Victoria (SECV) and more AC generation was installed and the changeover of customers was accelerated. This is around the time that the Synchronome Frequency Checking Mast Clock was installed at the Wendouree Parade Power Station. The SECV Annual Report of 1921 states: ::Section 11 of the act directed the COmmission to enquire into the question of securing the adoption of such standards of plant and equipment of a system, frequency and pressure for the generation and distribution of electricity as will admit of the efficient interconnection of undertakings throughout the State. In 1934 when the SECV took over the Ballarat operations the question of linking with the State grid had been a planned operation for some years but due to financial considerations had hindered it and in fact would continue to do so for a further 10 years. So while the need for close frequency control for interconnection was hardly an issue, the need to keep electric clocks correct was important, particularly as this item was a frequent sales point to cover the inconvenience and sometimes expense of converting from DC to AC. The clock is a very accurate pendulum clock with provision for varying effective length during operation for precise time regulation. There are two normal time dials and one is controlled by the pendulum and the other is operated by the system frequency. When the clock was in use it was installed by the MEter and Tests Laboratory and the time was checked daily by radio time signals. The two dials were repeated in the operators control panel in the Power Station. A maximum deviation between the two dials was set in the operating instructions (eg 5 seconds) and the operator would correct this when necessary by remote manual alteration of the turbine governor set point. The clock was used to drive and regulate a system of "slave" clocks which were used to display the time in various locations around the power station. A slave clock is a simple clock which is driven by a small electric motor, its accuracy is regulated by the master clock every 30 seconds to ensure that it and all the other slave clocks in the station are on exactly the right time; slave clocks were placed in various locations, from common rooms to workshops. A master clock could potentially run thousands of slave clocks at one plant. The clock also contains a rectifier. A rectifier is a device that is used to convert AC power to more stable DC current.Two clocks in a timber case. Both are electric, one is powered by the main pendulum mechanism, the other is a self contained electric clock. The main mechanism is of the gravity arm and roller type, which sends an impulse to the slave clocks every 30 seconds. The This Synchronome Frequency Checking Master Clock was used at the Ballarat Power Station. Below the main section of the case is a smaller cabinet containing a rectifier to provide consistent DC power for the clock. The rectifier was made by the Victorian company Hilco, which was located in Burwood. There is a high chance this is not the original rectifier from this clock as there appears to be brackets to hold a larger device in the space the rectifier occupies.Front below main clock face on front of case: "Patented Sychronome Brisbane" Lower left-hand clock face: "Frequency time" Lower right-hand clock face: "Standard Seconds" Synchronous electric clock mechanism on door (Frequency time clock): >200/250 V. 50~ >"Synchronomains" Made in England >Direction indicator for clock starting switch >"To start move lever in direction of arrow and release" >"Patent applied for" Mechanism for "standard seconds" clock: >"English Made" >"Patented" >Serial number "321" >0 above right-hand pillar on front-plate Mechanism for "standard seconds" clock: >"English Made" >"Patented" >Serial number "321" >0 above right-hand pillar on front-plate Mechanism for main clock face: >"English Made" >"Patented" >Serial number "8751" >0 above right-hand pillar on front-plate Inside case, back panel, top enamel plate: >Seconds Battery + Pos. > Battery Common or - Neg. >1/2 min dials Inside case, back panel, bottom enamel plate: external seconds dial Inside case, right hand side, electrical knobs: two switches, both "A.C. mains" Pendulum rod, below suspension spring: Serial number (?) 0000005 Rectifier in bottom cabinet: >"Hilco Rectifier" >"A.C.

he subject item is a pedal-powered rip saw with a tilting table made in the USA by W.F. & John Barnes Co. of Rockford, Illinois, between 1874 and 1890. The saw's blade moves rapidly in a circular motion and is driven by a pedal that spins a heavy flywheel with a leather belt attached to a gear drive that in turn drives the circular saw blade. The operator holds a wood workpiece on the table and moves it forward so the blade cuts it to the desired width and length. Company History: WF & John Barnes Co. was established in 1869, by making a formal partnership between William F. Barnes and John Barnes in 1872, and then incorporating in 1884. This company was an early manufacturer of pedal-powered equipment. By 1881 they were also making powered machinery such as lathes and pedestal drills. Many companies were making lightweight foot-powered equipment, but Barnes and the Seneca Falls Co. were the only ones to also make professional-grade workshop machines. From the beginning of their existence, they focused on pedal-powered machinery and specialised in making scroll saws. By 1937 the company focus had completely shifted to automotive assembly machinery, and custom-built machinery, machine tools, electrical, hydraulic, and mechanical controls and systems, including nuclear hardware. their production of foot-powered machinery had ceased. In the intervening years, they have got out of manufacturing completely. After a series of ownership changes, their equipment parts and stock were purchased in 1998 by LeBlond Ltd. of Amelia, Ohio.

Singer was first established as I. M. Singer & Co. in 1851 by Isaac Merritt Singer with New York lawyer Edward C. Clark. Best known for its sewing machines, it was renamed Singer Manufacturing Company in 1865, then the Singer Company in 1963. The Singer company began to market its machines internationally in 1855 and won first prize at the Paris world's fair that year. They had offices established in both Sydney and Melbourne by the mid-1960s. The company demonstrated the first workable electric sewing machine in 1910. Singer was also a marketing innovator and a pioneer in promoting the use of instalment payment plans, making their machines more affordable for many people. According to its serial number, this machine was manufactured in 1950 and was one of the new models designed to be more portable as it only weighed about 10 KG.This sewing machine is of local, national and international significance as it represents developments in technology and the impact this had upon the work of women.The Singer 99 was a sturdy and reliable machine that was easy to use. Lighter than other machines of its time, this machine weighed only 10 Kgs. It is mounted on a wooden base with a small compartment under the balance wheel to store accessories and bobbins. It has a 'Bentwood' (polished plywood) cover which also provided some room for storage. The machine is driven by a small electric motor and a light to illuminate the work area. It is decorated with gold decals and a filigree pattern. It includes a knee control which is inserted in a hole at the front of the machine. The serial number EG045782 indicates it was manufactured in 1950.Across the top in gold script: "The Singer Manufacturing Co. / Made in Great Britain" On light cover: "SINGER" Plate with specifications also attached.
