MERL 'Handwritten accession' form (Institute of Agricultural History) – 'Standard museum name: PRESSURE LAMP // Accession number: 93/49 // … // Recorder: JMB // Date: 8.9.93 // Description: This kerosene pressure lamp has a round, cream coloured tank at the base with filler/pressure pump at one side. The vertical pipe fits into a metal ring with a wider cap at the top. There is a control valve on the pipe. The mantle is damaged but the round glass cover is intact. // Inscription on glass: TILLEY // MADE IN IN ENGLAND // Dimensions: Height: 58.0 cm // Associated information: This lamp came from a house in Pell Street, Reading.’, MERL miscellaneous note, Greta Bertram, 20 May 2014 – Extract from an unknown text on lighting in the accession file, “There were many types of pressure lamps and lanterns, though the principle was basic: the pre-heating with methylated spirits of a generator tube. // When the fuel tank was pumped full of air the fuel was forced through the heated generator and vaporised, igniting as it left the tiny hole in the nipple or end of the generator. Simple to use, the main requirements are that the generator must be heated adequately and that sufficient pressure must be maintained in the tank, which gives a most economical result owing to the high proportion of air consumed. // Pressure lamps and lanterns were made by firms experience in the making of pressure stoves for they use the same principle as a Primus stove. It was possible to buy an adaptor unit which would stand on the top of a Primus stove and convert it to a mantle pressure lamp. The Swedish Primus, the American Coleman and the British Veritas, Tilley and Vapalux (Aladdin) accounted for a large part of the market in pressure lighting and though the domestic demand waned the portable lantern is still sold in quantity to industry and to the developing nations. The portable floodlights are still widely used in civil engineering projects and for emergency air strips, though many of them now use propane gas instead of paraffin. // Many Coleman lamps from North America were available with petrol as a fuel, but they were never widely used in Britain, possibly because paraffin was naturally considered a safer fuel for home use.”
