The Excelsior IV Log is a nautical instrument for measuring a vessel’s speed and distance travelled. When navigating a ship it is essential to be able to estimate the boat’s speed and distance travelled to determine its position at sea. 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 speed of the vessel through the water. This was known as streaming the log and is also the derivation of the knot as a measurement of nautical speed. The Walker’s Excelsior Mark IV instrument was designed for smaller vessels, such as yachts, launches and fishing vessels. Historical: Thomas Walker & Son was internationally renowned in the manufacturing of ships logs, founding father , Thomas Walker (1805–1871), an engineer in Birmingham, patented a 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 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 kick starting 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 (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 the time of 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 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.Ship's Taff Rail Log, rope attached. Walker's Excelsior IV Log model.

Used on Gabo Island to measure maximun gust over previous 3 hours or between weather observations. Information on the back of the device implies that it was battery powered and indicates that it was used in conjunction with a Synchrotac brand anemometer. Its particular function was to measure maximum wind speed over three hours between weather observations. Like the other weather recording instruments in the collection, it became redundant to the Bureau of Meteorology’s needs. It is a good example of its kind and has first level contributory significance for its historic value and provenance to the lightstation.Black metal box with grey metal front.

This Timing Relay is quite a large (industrial type) apparatus. The Timer is started by having a voltage of 250 volts direct current (as supplied by batteries). A DC motor then rotates driving into a clockwork mechanism, the output of which is an arm rotating at the same speed as a minute hand on a clock. Attached to this arm is a mercury switch which tips and makes an electrical circuit operate in a sequence control system. The sequences that use these timers are when starting and stopping Hydro Generators. They check that the machine has connected to the power system grid before 20 minutes duration. Brakes must go on for a set time when shutting down a generator slowing at the right speed as measured by this apparatus. These generators are powered by the hydro force of "stored" water at a higher altitude. The establishment of both the NSW and Victorian Hydro schemes was achieved from the mid 1900's to the 1960's. At this point in time the need for additional power sources to quench both an industrial and domestic demand for electricity was purely an economic and not and environmental (carbon reduction) factor. This Timing Relay apparatus is very significant to the Kiewa Valley as its use was introduced during the Kiewa Hydro Scheme. Although only a relay apparatus, it was however part of the explosion of human resources into the valley. This influx of population transformed the region from that of a basically quiet rural region to one which evolved into both an industrial and a larger residential community. This evolution in the valley created a change, not only in the "physical" landscape but also the socio-economic expansion which permitted other "tourist" based industries into the valley. This Hydro Scheme was instigated by "the Government of the day" as a bold move and was the major force behind the acceptance of World War II refugee and "technical" workforce. Inclusion of skilled and unskilled migration into the Australian environment was of a higher priority than a selective quota system of later years.. Although this mass "invasion" of workers with families was thought of in some circles as intrusive, the expansion of population post war years and its integration into the Australian rural sector, produced the multi- lingual, multi-cultural diversity of later years.sec vic kiewa hydro scheme, alternate energy supplies, alpine population growth

This post drill press has been made by Melbourne business, Dawn Manufacturing Company. It can be operated manually or by a pulley driven flywheel, with the aid of an engine connected to a power supply. In the late 1800s early 1900s a drill press like this would have been driven by steam from a boiler, the main power source for manufacturer’s power at that time. Dawn’s Golden Anniversary 1917-1967 Catalogue describes this model 611 drill as … “Ruggedly constructed with accurately reamed bearings. The coupling between the main spindle and feed screw engages the full circumference of the spindle, and embraces a ball-bearing thrust race. The pillar, as in all “Dawn Drilling Machines” is a solid bright steel bar, in place of the usual light tubing. Adjustable automatic feed.” And “F. & l. Pulleys extra, if required”. DAWN MANUFACTURING CO. The Dawn Manufacturing Co. was founded in Coburg, Melbourne, in 1917 by the four Blake brothers, who were all engineers. After World War I Dawn was supplying drills Australia wide and the company was growing at a healthy rate. During the depression they remained busy, with employees working 60-80 hour weeks. Dawn was contracted to supply vices and clamps to the Australian Defence Department and munitions factory during the World War II. - 1959 the company was taken over by G.N. Raymond Group. - 1967 the Dawn Manufacturing Co. had distributors in Australia and overseas, including USA, Canada, New Zealand, Asia and the Middle East. - 1973 the Siddons Ramset Limited acquired Dawn. - December 1991, Dawn became a unit of the United States owned Stanley Works Pty. Ltd. - November 1998 Dawn became 100 per cent Australian owned. The drill is a typical tool of a blacksmith, cart wright, wheelwright and garage business. It is an example of the tools of the blacksmiths’ trade in Victoria in the early to mid-20th century.Post type drill press machine with gear driven flywheel. Drill press is attached to a post and is fitted with a pulley belt and will run at a speed of maxim 200 r.p.m. The machine can also be manually operated.
