An indoor paraffin lamp from Aladdin, rated 250 CP in a catalogue from 1911. It probably dates from the years around 1910. Aladdin was founded in 1905, but disappeared as a freestanding company as early as 1913 when AB Lux managed to buy the entire stock as a result of a patent feud Aladdin lost in favour for AB Lux. Unfortunately Aladdin stayed as a subsidiary under Lux with its own name, so it's not to be absolute certain that an item from Aladdin must be from the period 1905-13. It might date a few years later. Aladdin plagiarized freely many things from Lux (hence the lost dispute), and the tank for this lamp is no exception. Apart from sheer looks, It also has the same separate high pressure compartment for the air and a very "Lux-alike" combined bleeder/regulator valve. The high pressure compartment shall be filled with around 6 bars of air, and that will last a long time since the lamps only use around the regular 1,5. The fuel compartment is vented to the atmosphere when the regulator key is turned to the "OFF"-position. When turning it to "ON", the fuel compartment will be sealed off from the atmosphere and the regulator valve will instead apply a well regulated pressure of the mentioned 1,5 atm from the high pressure part of the tank. It works like a charm! The mantle I used in one of the pictures is actually meant for a Lux Inverella, but I put it there to show that they used the same size for the ceramic ring. The mantle for this Aladdin should probably be a bit longer though. In the third thumbnail you can see the attachment for the fuel feed, the little funnel with its lid where you pour the preheating meths and since I removed the covering plate also the jet pointing upwards to the mixing chamber. Unfortunately the cleaning needle mechanism is missing (it should be attached where you see a plate with four threaded holes).
