Last week I found this Swedish beauty. It looks like a lot of parts are missing. I could't find any information of this lamp on the internet. Also here in the reference gallery is no information or pictures of another lamp. Is there someone who has information, maybe pictures from another lamp of the missing parts?
Lux lamps are in general rare, and the ones with a ring shaped tank (do-nut tank) are even rarer since most Lux lamps used a separate tank with a hollow wire. Your lamp came in both variants, and below is a page from the Lux-invert paper with your version of the lamp. Yours is the third (last) of the variants listed, and the text there says: Lux-invert with a ring shaped tank, consisting of a combined kerosene and air container surrounding the chimney of the lamp, including manometer but no reduction valve. Normally Lux lamps were pressurised with co2 under high pressure, and those needed a reduction valve. Yours is the for us more "normal" kind with regular air pressure, hence the lack of a reduction valve. It uses a loose foot pump that attach to the valve under the little lid screwed on top of the actual fuel lid. The paper dates from 1912 In a later paper from 1915 they state that the air pressurised one with a do-nut tank was for outdoor use, which make sense since indoor lamps used a hollow wire system and a remote tank. The outdoor lamp was rated 400-700 CP depending of pressure.
Thanks for the information, it's much appreciated. Now I hope that there is someone who also has such a lamp and is complete, so that I can get a better picture of how the burnerhead and the attachment of the glass looked like
Good luck on that! Lux lamps in general are rare even here in Sweden. Regarding the attachment of the glass, Lux generally had a metal mesh surrounding the globe which was tightened up to a ring that locked it all up to the lamp. And unfortunately it is all missing on your lamp. But from the pamphlet I posted, you atleast can get an idea of what the globe itself should look like.
Hi Johan, Yes, I saw that lamp on a Swedish auction site and I noticed that probably burner parts were missing. Around ten years ago I had a Lux Invert donut lamp that I later traded to a Swedish collector "Mr. Lux", Birger Väremo. I understood that Birger was better suited to restore this more or less complete Lux lamp and I was right in my assumption, as Birger did a great job on that lamp. I know he had a hard time to fettle the burner into a functional condition but he managed to fix it and also a new shade globe to it, that had been missing. On a Primus Meeting 2017 he showed the lamp in working order and I will attach a photo of it from that meeting. The photo was taken, I think, by Bo Ryman, and I hope it is OK to show it here on CPL. As Christer already has said, these are very rare lamps and I know only of Birger with a working Lux Invert donut example. I'm sorry, but I don't think he is active in forums and also not active in social media. /Conny
I have one myself but unfortunately missing the burner and the glass, just like yours. I have had it for approx 50 years but not been able to complete it. So it is really tough. Mine was converted to electricity, like many of these oldies. Good luck in finding the missing parts. Bo
I got the Lux invert working. Original parts are not available, or possible to find. So I made a burner myself, and bougt a big glass. A glass from a petromax 835 is to small. Action photos here
