Hi all, This is the mid 30´s Akron 150 vase lamp made for Montgomery & Ward/Chicago. The lamp is equipped with the "infamous" Instant-Glo burner unit. I've tried to figure out the idea behind the Instant-Glo format from the 1933 patent and I must say it is most intricate and complicated. Although interesting engineering burner wise; it must have been many things here that could go wrong. The burner has three different "valve housing modes" that is regulated by the control knob. From what I've learned of the patent the two end positions with a pressurized tank give you either "shut off" or "fuel only" and the intermediate position gives a mix of air and fuel for "cold lighting" the burner. When the generator gets hot you have to switch on to the "fuel only" position. The only way I could get the burner to function was to treat it as a conventional burner unit and after some generator pre heating switch on to the "fuel only" mode. The patent you can find here - https://www.google.com/patents/US1920933?dq=akron+lamp+company&hl=sv&sa=X&ei=vYoLVKnNKaaCzAOA-III&ved=0CB0Q6AEwAA The lamp was easy to get in order; just needed some cleaning. I've waited a long time to get a nice parchment replacement shade to put on this vase lamp but couldn't find any. The original shade is probably impossible to obtain, but the paper shade I now found looks OK. /Conny
Very nice Conny, congratulation on a fine lamp . The burner almost looks like the gasoline-burner from my Leacock 107 - on the outerlook that is. The shade fits the lamp well Claus C
