Megger as the device was called, is in fact its brand name. It is a device that supplies a DC (direct current as per car batteries) voltage to enable testing of electrical apparatus. This particular device produces 250volts DC when the handle is turned vigorously. If an electrical device, such as a kettle or toaster, blew a fuse or tripped a circuit breaker, when switched on, then it must be checked electrically before any more use. Following the repair of the faulty item a megger would be used to check if either of the AC 240volt plugs leads were touching the metal case (earth). The output leads of the megger would be connected with one to the earth (metal case) and the other to each of the power connections in turn. A good megger reading of 50,000 ohms (resistance) would enable the device to be returned to service. A reading of zero ohms resistance would mean that it would again blow a fuse, and was therefore unsafe to use. In the electrical industry e.g. the former State Electricity Commission, a megger would be used to test lots of similar item in sequence. Because of the vigorous job of winding the handle, two persons were often used to save time. One would crank madly whilst the other shifted the leads. This particular megger is of a small voltage, but other meggers are bigger and have a few ranges of DC voltages able to be selected. The optimal megger for large Generating machines was motor driven megger. This was applied to the device being tested for a duration of approximately 30 minutes with reading of the resistance taken at regular intervals.All equipment belonging to the State Electricity Commission of Victoria was labelled with a metal plaque attached to it. The SECV constructed the Kiewa Hydro Electric Scheme in the Upper Kiewa Valley and on the Bogong High Plains. The scheme began in 1938 and finished in 1961 when this megger was used and also possibly later as the SECV remained to maintain and operate the Scheme. This megger is of significance in relation to the advancement of technology.A rectangular box in dark brown bakerlite casing. It has an agent's plaque fixed to the left of the face and on the right is the marker's recessed stamp. In the middle in a transparent window so the level of ohms can be read. The front also has two recessed fixing knobs in black. On one side is a crank handle with a knob that lifts up and is turned vigorously to create the voltage.

This is the MINJAH telephone exchange testing unit. The exchange was adjacent to the property of MINJAH which is situated near Hawkesdale in Western Victoria. The exchange operated between 1955 and 1985. The testing unit was used for detecting and testing faults in the telephone system. The keys along the front were called "Hospital Keys" and were used to give subscribers a temporary connection in the event of a break down. The telephone exchange was replaced by an automatic exchange.This is a good example of a manual telephone system in Western VictoriaThis is a rectangular polished wooden box with a telephone mechanism on the side connected by a hook.

This burgundy coloured, portable electric belt sander is stored in its own heavy duty cardboard box. It was made in England and, according to the label on the lid of the box, it is a Portrix Sander-Polisher, all-electric, portable, sands wood metal and polishes. Its uses include decorating, carpentry and polishing. It has a complete with electric unit with flex. The price of 75/- (75 shillings) is printed on the label of the box. The model and the brand of the sander have been removed from the manufacturer’s information embossed on the side of the sander. The sander 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. Please see our record 3732 of the mode Sovereign of the Seas for further details of the ship and the maker.This vintage Portrix sander-polisher represents tools used for the hobby and skill of ship model making that has been carried as a leisure activity out for generations. Ship model making was also a pastime for sailing crew, who often made a model of the ship in which they were sailing. This sander 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.Belt sander, electric.

In times past the only way to measure a ship’s speed was to throw a wood log into the water and observe how fast it moved away from the ship. In the 16th century, the log was fastened to a rope knotted at set intervals. The log was thrown over the stern (back) of the vessel and a crew member counted the number of knots that were paid out in a set time. From this, they could estimate the vessel's speed through the water. This was known as streaming the log and is also the derivation of the knot as a measurement of nautical speed. Various manufacturers of nautical equipment had sought over the years to perfect the operation of determining a ship's speed and it wasn't until Thomas Walker and his son Ferdinand developed a mechanical system that eventually made this task became easy for marine navigators. Thomas Walker & Son were internationally renowned in the manufacturing of ship logs the founding father, Thomas Walker (1805–1871), an engineer in Birmingham, patented his mechanical log in 1878 which was a recording instrument that attached to a rail at the stern of a vessel connected by a long cord with a rotor which was towed behind the ship. The instrument dial then recorded the distance travelled. Thomas Walker first went into business to manufacture stoves at 58 Oxford Street Birmingham. Walker’s self-feeding stove was widely lauded at the Paris Exhibition of 1855, winning a prize medal and kickstarting the first of many notable innovations for the Walker family's manufacturing business. However, it wasn’t until working on an earlier ship’s log model invented by his Uncle that Thomas Walker became interested in the further development of this device, used to ascertain a ship’s speed. Walker continued to improve on the common log for the company of Massey & Sons and these improvements were deemed revolutionary. This log became a firm favourite of the West India Association (a British-based organisation promoting ties and trade with the British Caribbean), being the most common log in use for two generations. It took until 1861 for Thomas Walker and his son, Thomas Ferdinand Walker (1831-1921) to patent the first Walker log of many. Together, with the introduction of the A1 Harpoon Log two years later, they established the Walker Log Business as a force to be reckoned with. By his passing in 1871, Thomas Walker Snr had not only founded a family business with considerable staying power but also instilled a tradition of public service. Having sat as a representative on the Birmingham Town Council for 15 years and played an active role in public works, he was soon given the nickname of ‘Blue Brick Walker’. Much like his father, Thomas Ferdinand Walker changed the face of the maritime industry. His patent of 1897, the ‘Cherub’ log, was a notable departure from the past providing a far more accurate reading and replacing the majority of logs of the age. They were the first to produce an electric log (Trident) and the Walker factory was one of the first to introduce the 48-hour work week for employees.The ship log was invented and made by a significant marine instrument maker and innovator of machinery. It demonstrates the huge leap taken to improve navigational accuracy at sea with an instrument that was in use for decades.Ships Log, Walker Trident electric motor, in wooden box with instructions inside box.

c1881 Henry W Seely, of New Jersey, USA, designed and patented an electric sad iron for pressing and smoothing material. He continued to modify and improve his designs, with his partner Richard Dyer, and other electrical appliance firms, e.g Hotpoint, began producing these flat irons that could provide continuous heat by connecting via an electrical flex to a light socket and hence without the need for hot fires, ash, or burning hot handles. Women with access to an electricity supply were delighted and their ironing chore became much less arduous No heat was felt at all from the iron as it is all concentrated on the bottom surface. By the early 20th century enthusiasm was building for the new electric smoothing irons: clean, powerful, adjustable, and labour-saving.
