Stand, pump & tank

Historical information

Was the stand for a Chance Brothers air & oil containers fitted with pump handle & pressure gauges.This type of installation was once common and relied on the lightkeeper having to pressurise the cylinders manually at regular intervals throughout the hours of darkness. The oil was fed under pressure to the burner mantle. It is all that remains of an air and kerosene oil tank installation, with each rounded side formerly supporting a heavy iron tank. The containers would have been fitted with a pump handle and pressure gauges. An intact assemblage is displayed in the AMSA offices, Canberra with a text that explains ‘This type of installation was once common and relied on the lightkeeper having to pressurise the cylinders manually at regular intervals throughout the hours of darkness’.The system involved vaporising kerosene under pressure and mixing it with air and then burning the vapour to heat an incandescent mantle. The use of kerosene as a fuel to light the lantern became the most common system of illumination from the 1860s after the oil industry in the United States began to develop. The kerosene vapour burner was created in 1901 by British inventor Arthur Kitson (1859-1937) and perfected by Chance Bros for burning a more intense light in their renowned lenses. The lamp had to be watched throughout the night in case a mantle broke, and the tanks needed to be maintained by hand-pumping each hour or so. The Point Hicks lantern was initially lit by a six-wick Trinity house kerosene burner. This was replaced by the more efficient and brighter 55mm vaporised kerosene mantle burner in 1905, and the tank stand is probably original to this apparatus. Electricity eventually replaced kerosene at Point Hicks in 1964 making the tank installation obsolete, and the last kerosene system in an Australian lighthouse was replaced in 1985. Gabo Island Lightstation has a pair of tanks that are not attached to the optical system and are no longer in the lighthouse. They are also missing the pressure gauges that were formerly attached to the top of each cylinder. An intact tank assemblage is displayed at the Cape Schanck Lighthouse Museum it is detached and not original to the lighthouse.

Significance

Although corroded, the remnant Point Hicks tank stand has first level contributory importance to the lightstation. It is significant for its provenance and historical value as part of the Chance Bros vaporised kerosene burner introduced in 1905 to intensify
the light and improve the efficiency of the system.

Physical description

The rusted iron stand rests on four short legs and is shaped like a pair of spectacles.
