A marine foghorn gives an audible navigational signal to warn vessels of dangers, hazards and the presence of other vessels in fog conditions. The foghorn signal is a series of long and short sounds with short or long pauses between them. These common signals conform to a code called the International Regulations for Preventing Collisions at Sea and provide such information as whether the vessel is under sail or motor, large or small, aground or at anchor. The designs of foghorns vary but they all use a column of air to make a loud sound. Some use vibrating plates or metal reeds, others force air through holes in a revolving cylinder or disc, sounding like a siren, and some use a clockwork mechanism to open the valves that let the air into the horn. They are usually built to meet particular specifications e.g. U.S.C.G. (US Coast Guard). This Tyfon plunger foghorn has a horizontal handle attached to a vertical rod that moves up and down inside a cylinder. When the handle is plunged down, in a similar way to a bicycle pump, the air is forced out of the bottom of the cylinder into a pipe with a bell-shaped horn on the end, making a loud, low sound. The wider base of the cylinder helps to keep it stable. The original type Tyfon foghorns were manufactured in about 1910 by Kochums Mechanical Workshop (Kockums Mechanical Werkstad, Ltd.), Malmo, Sweden. The company was established in 1840, became a Limited company in 1866, and established a shipyard at the Port of Malmo, Sweden, in 1870. The civilian ship production in Malmo ceased in 1987. As well as building ships the company built large industrial and agricultural machinery and maritime goods.this replica foghorn represents the design of a Swedish, Tyfon model 1910. It is an example of the type of safety equipment used on marine vessels to signal other vessels and signal to land. Replica foghorn; portable marine, plunger operation.

An hourglass or sandglass is an instrument for measuring a defined time and can be used perpetually by simply turning it over immediately the top bulb empties. The clear blown glass is shaped into two equal sized bulbs with a narrow passage in the centre and contains uniform sized sand or glass particles in the lower bulb. The width of the neck regulates the constant flow of the particles. The glass is held in a stand with top and bottom of equal shape and size. Hourglasses can measure an infinite variety of time by gauging the size of the particles, the shape and size of the bulbs and the size of the passage between the bulbs, thus measuring hours or minutes or even seconds. Generally an hourglass sits between discs of wood at the ends, which are joined by long wooden spindles between the ends and tightened by screw caps. The length of time can be adjusted by adding or removing sand particles. The use of the marine sandglass (or hourglass) has been recorded in the 14th century in European shipping. A one minute sandglass was used in conjunction with the ship’s log for ‘dead reckoning’, (see below) that is, for measuring the ship’s speed through the water. They were also used to regulate ringing the ship’s timetable; for example a 4 hour sandglass was used for the length of the sailors’ watch, and a half hour timer for taking of readings for the ship’s log; the ship’s bell would be rung every half hour. It was usually the role of the cabin boy to watch and turn the sandglasses over at the exact time of them emptying their upper chambers and to ring the ship’s bell. Hourglasses have been used historically for many hundreds of years. Some have been used for timing church sermons, in cooking, in industry and at sea. Even today they are used for measuring the cooking time of eggs and timing a player’s turn in games such as Boggle and Pictionary. The sandglasses at sea were gradually replaced in the late 1700’s to early 1800’s by the more accurate chronometers (marine clocks) when they became reliable instruments. DEAD RECKONING (or Deduced Reckoning) Dead reckoning is the term used to describe the method of calculating the ship’s position from its speed and direction, used in early maritime travel, mostly in European waters. Both the (1) speed and the (2) direction of travel were recorded on a Traverse Board at half-hourly intervals during a helmsman’s watch of 4 hours. The navigator would record the readings in his ship’s log, plot them on his navigational chart and give his updated course directions to the next helmsman on watch, along with the cleared Traverse Board. This was a very approximate, but none-the-less helpful, method of navigation. The wooden Traverse Board was a simple pegboard with a diagram of a compass with eight peg holes along the radius to each of the compass points, plus a grid with ascending half hours in the left column and increasing ship’s speed in knots in a row across the column headings, with a peg hole in each of the intersecting cells. A number of wooden pegs were attached to strings on the board. By placing one peg consecutively in the direction’s radius hole, starting from the centre, and the speed holes when the half hourly reading was taken, a picture of speed and direction for the whole 4 hour watch was created. (1) To measure the ship’s speed a one minute hourglass timer was usually used to measure the ship’s speed through the water and help to calculate its longitude. A rope, with knots at regular standard intervals and a weight such as a log at the end, would be thrown overboard at the stern of the ship. At the same time the hourglass would be turned over and a seaman would start counting the number of knots on the rope that passed freely through his hands as the ship travelled. When the timer ran out the counting would be stopped. A timer of one minute (one-sixtieth of an hour), knots spaced one-sixtieth of a nautical mile apart, and simple arithmetic easily gave the speed of the ship in nautical miles per hour ("knots"). This would be recorded every half hour. The speed could however be inaccurate to the travel being affected by ocean currents and wind. (2) To calculate the ship’s direction a compass sighting would be recorded each half hour.Marine hourglasses or sandglasses were used from around the 14th to 19th century during the time of sailing ships. This hourglass is representative of that era, which is during the time of the colonisation of Australia. Hourglass or sandglass; an instrument used to measure time. Two equal sized clear glass bulbs joined with a narrow passage between them, containing equal sized particles of sand grains in lower bulb.

In the 19th century, the Industrial Revolution meant that shipbuilders could build ships using iron. These iron ships could be much larger, with more space for cargo and they didn't need as much work to keep them in good condition. Isambard Kingdom Brunel's "Great Britain" built in 1843, was the first ship to be built entirely of wrought iron. In the 1880's steel began to be used instead of iron. Ships also began to be fitted with steam engines although a great deal of coal was needed to travel even short distances. For this reason, ships continued to be fitted out with sails even though many came with engines. The iron-hulled, four-masted barque, the Falls of Halladale, was a bulk carrier of general cargo. She left New York in August 1908 on her way to Melbourne and Sydney. In her hold, along with 56,763 tiles of unusual beautiful green American slates (roofing tiles), 5,673 coils of barbed wire, 600 stoves, 500 sewing machines, 6500 gallons of oil, 14400 gallons of benzene, and many other manufactured items, were 117 cases of crockery and glassware. Three months later and close to her destination, a navigational error caused the Falls of Halladale to be wrecked on a reef off the Peterborough headland at 3 am on the morning of the 15th of November, 1908. The captain and 29 crew members all survived, but her valuable cargo was largely lost, despite two salvage attempts in 1908-09 and 1910. ABOUT THE ‘FALLS OF HALLADALE’ (1886 - 1908) Built: in1886 by Russell & Co., Greenock shipyards, River Clyde, Scotland, UK. The company was founded in 1870 (or 1873) as a partnership between Joseph Russell (1834-1917), Anderson Rodger and William Todd Lithgow. During the period 1882-92 Russell & Co., standardised designs, which sped up their building process so much that they were able to build 271 ships over that time. In 1886 they introduced a 3000 ton class of sailing vessel with auxiliary engines and brace halyard winches. In 1890 they broke the world output record. Owner: Falls Line, Wright, Breakenridge & Co, 111 Union Street, Glasgow, Scotland. Configuration: Four masted sailing ship; iron-hulled barque; iron masts, wire rigging, fore & aft lifting bridges. Size: Length 83.87m x Breadth 12.6m x Depth 7.23m, Gross tonnage 2085 ton Wrecked: the night of 14th November 1908, Curdies Inlet, Peterborough south west Victoria Crew: 29 The Falls of Halladale was a four-masted sailing ship built-in 1886 in Glasgow, Scotland, for the long-distance cargo trade and was mostly used for Pacific grain trade. She was owned by Wright, Breakenridge & Co of Glasgow and was one of several Falls Line ships, all of which were named after waterfalls in Scotland. The lines flag was of red, blue and white vertical stripes. The Falls of Halladale had a sturdy construction built to carry maximum cargo and able to maintain full sail in heavy gales, one of the last of the ‘windjammers’ that sailed the Trade Route. She and her sister ship, the Falls of Garry, were the first ships in the world to include fore and aft lifting bridges. Previous to this, heavily loaded vessels could have heavy seas break along the full length of the deck, causing serious injury or even death to those on deck. The new, raised catwalk-type decking allowed the crew to move above the deck stormy conditions. This idea is still used today on the most modern tankers and cargo vessels and has proved to be an important step forward in the safety of men at sea. On 4th August 1908, with new sails, 29 crew, and 2800 tons of cargo, the Falls of Halladale left New York, bound for Melbourne and Sydney via the Cape of Good Hope. The cargo on board was valued at £35,000 and included 56,763 tiles of American slate roofing tiles (roof slates), 5,673 coils of barbed wire, 600 stoves, 500 sewing machines, 6,500 gallons of oil, 14,400 gallons of benzene, plumbing iron, 117 cases of crockery and glassware and many other manufactured items. The Falls of Halladale had been at sail for 102 days when, at 3 am on the night of 14th November 1908, under full sail in calm seas with a six knots breeze behind and misleading fog along the coast, the great vessel rose upon an ocean swell and settled on top of a submerged reef near Peterborough on the south-west Victoria’s coast. The ship was jammed on the rocks and began filling with water. The crew launched the two lifeboats and all 29 crew landed safely on the beach over 4 miles away at the Bay of Islands. The postmistress at Peterborough, who kept a watch for vessels in distress, saw the stranding and sent out an alert to the local people. A rescue party went to the aid of the sailors and the Port Campbell rocket crew was dispatched, but the crew had all managed to reach shore safely by the time help arrived. The ship stayed in full sail on the rocky shelf for nearly two months, attracting hundreds of sightseers who watched her slowly disintegrate until the pounding seas and dynamiting by salvagers finally broke her back, and her remains disappeared back into deeper water. The valuable cargo was largely lost, despite two salvage attempts in 1908-09 and 1910. Further salvage operations were made from 1974-1986, during which time 22,000 slate tiles were recovered with the help of 14 oil drums to float them, plus personal artefacts, ship fittings, reams of paper and other items. The Court of Marine Inquiry in Melbourne ruled that the foundering of the ship was entirely due to Captain David Wood Thomson’s navigational error, not too technical failure of the Clyde-built ship. The shipwreck is a popular site for divers, about 300m offshore and in 3 – 15m of water. Some of the original cargo can be seen at the site, including pieces of roof slate and coils of barbed wire. This particular artefact was one of many found by John Laidlaw (a local Warrnambool diver) when diving on the Falls of Halladale in the 1960's. In August 1973, John Laidlaw and Stan McPhee went on to discover the underwater location of the Schomberg - a passenger ship that ran aground on December 26th 1855 near Peterborough and which now lies in 825 metres of water. When John Laidlaw died, his family donated a number of artefacts to Flagstaff Hill. The brass finial may have been part of a larger decorative item such as a lamp or clock bracket.This item is significant as it was taken from the Falls of Halladale shipwreck which is listed on the Victorian Heritage Register (No. S255). She was one of the last ships to sail the Trade Routes. She is one of the first vessels to have fore and aft lifting bridges. She is an example of the remains of an International Cargo Ship and also represents aspects of Victoria’s shipping industry. The wreck is protected as a Historic Shipwreck under the Commonwealth Historic Shipwrecks Act (1976)A brass, bell shaped object with a body approximately 3 cm high. It has an outer lip, straight sides that taper in and a flat "cap". The inside of the object is plain with evidence of vertigris. It has a decorative topping almost 2 cm high which has a double concave hollow neck.flagstaff hill, flagstaff hill divers, flagstaff hill maritime museum and village, great ocean road, warrnambool, falls of halladale, falls of halladale wreck, shipwreck artefact, artefact, brass artefact, brass finial, brass fitting, shipwreck coast, diver, john laidlaw, finial, brass decoration, handmade
