Tank lid
Lid for ship's tanks used for early domestic water storage (1860's) at the lightstation The water tank and lid are probably from the same unit that was used for transporting drinking water or perishable dry goods on ships. The unit comprised a large, riveted metal tank which was fitted with a heavy cast iron round lid to form a hermetically sealed container. It had a rubber sealing ring ‘which was screwed tight with the aid of lugs cast into the lid and wedges cast into the rim of the loading hole’. A raised iron rod welded across the outer face of many lids allowed for screwing the lid tight. Ship tanks were invented in1808 by notable engineer, Richard Trevithick and his associate John Dickinson. Their patent obtained the same year described the tank’s superior cubic shape that allowed it to fit squarely as a container in ships and thus use space efficiently, while its metal fabric preserved and secured its contents, whether liquid or solid, from damage. The containers revolutionised the movement of goods by ship and made wooden casks redundant. Research by Michael Pearson has determined that they were carried on passages to Australia from at least the 1830s, conveying ships’ victuals and water storage as well as general goods heading for the colonies, and by the 1870s they were in common use. Once in the colonies, the tanks were often recycled and adapted for many resourceful uses such as water tanks, packing cases, dog kennels, oil containers and food stores and this invariably led to the separation of the lid and tank. Raised lettering on the lids indicates that nearly all of the ship tanks transported to Australia came from London manufacturers, and it was usual also for the brand name to feature as a stencil on the associated square tank but in most cases this eventually wore off. It is not known if the Wilsons Promontory tank retains its stencil, and the heavy lid will need to be turned over to reveal its manufacturer’s name. How it came to the lightstation is also not known, but it was either brought to the site as a recycled tank or salvaged from a shipwreck. Pearson writes that Ship tanks show up at a wide range of sites, many of them isolated like lighthouses. They were, I think, usually taken there for the purposes they filled, usually water storage, as they were readily available, relatively light to transport, and probably very cheap to buy as second‐hand goods containers. In rural areas they may have been scavenged for their new uses from local stores, to whom goods were delivered in them. Recycled to serve as a water tank, the Wilsons Promontory tank is the last surviving example of several that were used at the site to hold water for domestic consumption. The tank has had its lid removed and a tap fitted to the one of the sides. It stands on concrete blocks next to a building to receive water running off the roof via a metal pipe. Wilsons Promontory is the only lightstation managed by Parks Victoria with a tank container, although Cape Otway and Point Hicks have lids. Parks Victoria has identified four other lids which include two at Point Hicks, one manufactured by Lancaster and Co. the other by Bellamy. Cape Otway also has two, one unidentified and the other by the Bow Tank Works, East London, which produced tanks between 1910 and 1930. Pearson notes that ‘surviving lids are far less numerous than the tanks themselves, presumably because the uses to which the tanks were put did not require the lid to be retained’. The tank and lid, which are possibly part of the same unit, have first level contributory significance for their historic values and rarity. Round ship's tanks lid, iron. -

Lid, ship tank
The heavy cast iron, round lid was originally fastened into a large, riveted metal box, known as a ship tank. It has the name ‘John Bellamy London’ cast in capitals in a continuous circle on the outer edge of the lid face, and the words ‘Byng St Millwall’ on the inner circle. , of Millwall, London, manufactured boilers and ship tanks from the 1860s to the 1930s and came from a family of tank makers who began manufacturing tanks some time before 1856. Ship tanks were invented in 1808 by notable engineer, Richard Trevithick and his associate John Dickinson. Their patent obtained the same year described the tank’s superior cubic shape that allowed it to fit squarely as a container in vessels and thus use space efficiently, while its metal fabric preserved and secured its liquid or solid contents from damage. The containers revolutionised the movement of goods by ship and made wooden casks redundant. Research by Michael Pearson has determined that they were carried on passages to Australia from at least the 1830s conveying ships’ victuals and water storage, as well as general goods heading for the colonies. Pearson found photographic evidence of their use in the 1860s, and by the 1870s they appeared to be in common use. lids surviving from containers indicate that nearly all the tanks transported to Australia came from London manufacturers. It was usual for the brand name to also feature as a stencil on the tank but in most cases this eventually wore off. A tank without its original stencil survives at Wilsons Promontory. Tanks transporting ‘drinking water or perishable dry goods were hermetically sealed by the use of the tightly fitting lid with a rubber sealing ring ‘which was screwed tight with the aid of lugs cast into the lid and wedges cast into the rim of the loading hole’. The raised iron rod welded across the outer face of many lids such as the Bellamy example, allowed for screwing the lid tight. Once in the colonies, the ship tanks were often recycled and adapted for many resourceful uses such as packing cases, dog kennels, water tanks, oil containers and food stores and this invariably led to the separation of the lid and tank. The Bellamy lid could have been salvaged from a shipwreck but is more likely to have to have originated from a recycled tank that was brought to the lightstation for water storage purposes. Pearson writes that: Ship tanks show up at a wide range of sites, many of them isolated like lighthouses. They were, I think, usually taken there for the purposes they filled, usually water storage, as they were readily available, relatively light to transport, and probably very cheap to buy as second-hand goods containers. In rural areas they may have been scavenged for their new uses from local stores, to whom goods were delivered in them. Parks Victoria has identified five tank lids in the lightstation collections covered by this project. In addition to the Bellamy lid at Point Hicks, they include a Bow brand lid at Point Hicks and another at Cape Otway, unidentified lids at Cape Otway and Wilsons Promontory. Pearson and Miles Lewis have each recorded two versions of the Bellamy trade name on the lids; one being ‘John Bellamy Byng St. London’; the other, ‘John Bellamy Byng St. Millwall London’. The Point Hicks lid has the second version of the name, as do other examples in Victoria that Lewis has identified at Illawarra, Toorak; Warrock homestead, Casterton; Eeyeuk homestead, Terang; Ward’s Mill, Kyneton; and Boisdale homestead near Maffra, and in NSW at Ayrdale Park, Wolumla; and Bishop’s Lodge, Hay. Pearson’s list includes the same lids in NSW at Tumbarumba; the Quarantine Station, Sydney; Willandra Station; Bedervale, Braidwood; Gunnedah Museum; Walla Walla and Macquarie Island. The Point Hicks lid is currently stored in the lighthouse although it is unlikely that its use had any association with this building. The lid is in good condition and retains the central bung. Pearson notes that ‘surviving lids are far less numerous than the tanks themselves, presumably because the uses to which the tanks were put did not require the lid to be retained’.347 The Bellamy ship tank lid has first level contributory significance for its historic values. Circular cast-iron disc with raised outer ridge with inscription. It also has an inner depression with inscription. Two metal sections form handles over inner depression. Hole in middle of disc.Around perimeter of outer edge "JOHN BELLAMY LONDON" Around inner area "BYNG ST MILLWALL" -

Electrometer, Quadrant Elliot
Brass quadrant electrometer consists of four quarter-cylindrical brass boxes (quadrants ) each mounted on a glass insulating pillar. The whole is housed within an electrostatic shield (Faraday cage) - a beehive shaped wire cage enclosure (aka a “bird cage”). The quadrants and cage stand on a round base platform on three legs with levelling screws (tribach base?). Arising from the platform is a separate vertical rod arises from the periphery and terminates over the axis of cylindrical symmetry and from which provision is made for a conducting suspension fibre which supports the horizontal “paddle” which is free to rotate within the cylindrical cavity of the four quadrants. The suspension and paddle are unfortunately missing.Label on front: “Natural Philosophy Laboratory No. University of Melbourne” Engraved on front: “Elliott Bros London” -
