Hi, My lastest cute lantern. Changed the seals. Gave a good polish. Revealed some old shiny beauty. Regards willi
Yes, heatshield of stainless steel . This reflects the light. And makes the light even brighter. And prevents the tank from heating up too much. Regards Willi
In German, this special version of tank and main body is called "Sicke". How is this being translated to English? "crimp" ? Regs Willi
Hi Willi, I really like the Petromax N°821/250 HK. It is a very reliable little lamp, i have four copies that i often turn on. Congratulations for the beautiful quality of the pictures. Thank you so much for sharing. Best regards, Titoo
Hi @bp4willi , in another post I used the term "indentation" to explain, but I'm not sure whether that's correct... Maybe "notch" would also do. Regards, Martin
I haven't checked my German/English dictionary yet, but Google Translate has 'Sicke' as 'Beading'. Perhaps the tank is crimped to form a bead (i.e. a length of seal) of some sort, possibly referring to the way the seal around the tank base was made...
Hi @David Shouksmith maybe that picture illustrates what "Sicke" means in German. I also saw the word "beading", but was not confident with it being translated backwards by Google or DeepL, since it seemed more to be what is the German word "Bördelung". However, "Beads" would most likely be correct, according to this page. This construction element is mostly used to gain more stability for sheet metal pieces or at bending seams of sheets. Regards, Martin
Thanks David and Martin. Yes, beads seems to be the proper name for the dents in the upside of the tank, in which the "feet" of the main body lock when put on the tank. Regards willi Maybe an admin can ammend to the subject of this thread ".... Sicke/beading....."
Last year in Ontario Canada I was at an antique sale and bought a Petromax model 826 300cp " sicken tank " about 1955 model. Original globe thank you. Plan on cleaning it up this summer and will post photo's. Do not see original Petromax lanterns around here very often. Cameo
I think we'd use the word 'corrugation' for that. In addition to corrugations, pressing a shape into sheet materials is a well-used method to add stiffness and stop them flapping about...
It could be my eyes or the camera angle, but the old girl seems to be a tiny bit tilted to one side. The second image shows it quite distinctly. Hardly surprising on a lamp this age but are you considering gently getting it back into alignment again or will you leave it as it is?
@David Thanks for the miracle from remote. @eiremax the 350cp Petromax is the larger one, same size as the 500cp. This 250cp is similar in size , proportion and brightness to a Tilley.
Could be but in this case it was all about heat transfer. The horizontal ribs, holes and feet (Sicke) of the Petromax had all to do with heat transfer to the tank. or better find a way to get rid of the heat before it reached the tank.
Yes, I agree. However, the approach was not successful at all: The four bars at the frame which build the contact areas were too weak. After that was revealed, the frame design was changed to the last that was fabricated: with the ribbed frame base and rectangular holes.
Can I ask why the pricker valve control wheel has the word Petromax in mirror writing? Was that a 'thing' for some reason?
It's not in mirror. It's just upside down on the picture. If the wheel is turned 180 degrees so the arrow is pointing upwards, the text will be correct.
