  • Geniol?

    Zitat

    Original von Neiljohn
    Picked up a rather sad looking lamp at the dump this morning, only identifier on the plate is 'Lanterne' and '250CP Automatic' I think its probably a Geniol? It also has a rapid lighter.
    It needs a new glass and mantle and the coleman fuel draining out and refilling with paraffin, oh and completely straightening out, looks like it was dropped on its side as the vapouriser is bent!
    Not bad for £1 even if its not a go'er. :applaudit:
    Over a year since last visit, too busy with work following a huge fire there, due to an electrical failure. So busy I've also had to give up Scouting. :traurig:


    Hi,


    I think that for that price it's a great find, even if goes only for spare parts!


    Be sure to check that the bent vapouriser was the only part that suffered from being dropped, I mean that there isn't any signs of breakage/leak in where the vapourizer is attached into the tank. Pressurizing the tank and dipping it into a bucket full of water should be a good test, watch for bubbling.


    I hope you'll have a chance to be back in scouting some day, the good thing is that it's a habit that one does not completely forget easily, I too had a 10-year break before the second round :)

    aahm - let me say it in this way:


    Your lantern is not that ordinary, collectors would watch out for one in this good conditions. It was produced in this way in the late 1920ies and early 1930ies, so ceep a good look on it :naughty:


    Best regards, Björn


    Thanks, I appreciate these old lanterns and try to maintain them respectfully. Here's a family photo of my three E&G stamped Maxes, the new red top happily together with the two earlier aquired ones:

  • 828 Rapid, pre-heater maintenance


    Björn, thank you for this additional info! I will take a look if I can replace the whole gasket unit with a better one, or if finding a suitable factory-made one is impossible, just try to put a better "filling" into the current one by using some suitable material, maybe a piece of rubber or something. The curernt gasket is so flat and hardened it's no wonder it's not tight.


    PS: another question to anybody interested: This lantern has a separate manometer, not one that is integrated with the tank cap. How unusual this is? The manometer has Petromax logo text in it, and the fixing point in the tank looks like it's factory made.


    Cheers, FM

  • 828 Rapid, pre-heater maintenance


    Hi and thanks for the reply! I will try to take some pictures soon, after I have cleaned it a little bit.


    Overall condition is OK but it has some minor corrosion, the handle is bad and tank has taken couple of small hits.
    I think it's probably fully original, it has a tank marked with EG, a two-color needle knob, a separate manometer and an original Jenaer glass.


    This is the first Rapid model I have ever had. I don't know if the spoon alone should be able to hold the pressure (I don't see any gasket there), or how it is supposed to work?


    I would like to keep the original rapid if possible, for the looks and originality, but if it is unusable, I may have to replace it. This model does not have a spirits cup.


    Have a nice day!

  • 828 Rapid, pre-heater maintenance

    Hello,


    I found a red-top 828 Rapid with a preheater torch of "Löffelrapid" type (is there an English name for that?). The lantern seems otherwise to be a promising restauration project, but it's letting the pressure out from the preheater torch: more accurately the nozzle can't be blocked well enough to keep the pressure in. Do you have any tips I should try? I haven't disassembled it yet, as it seems to be well stuck and I'm worried if using force could broke something. Are the current preheater spares suitable for this "löffelrapid" variation?

    now we would like to see it burning :D


    Hi Doron,


    Altough the lantern obviously needs to have yet more restoration (it seems that my soldering work was not as superb as I thought, as it apparently reduced but did not end minor leaking from the bottom), I could not avoiud the temptation to have a test run when I got suitable mantles. You can see the result below :)


    I also bought a new nipple and a needle (meant for Px 250HK, as there were none availabe with the original 200HK spec), no problem fitting the needle but it appears that the nipple is slightly too wide to fit comfortably in the carburettor (did not want to force it violently). So I had to do this with the old and maybe quite worn nipple.


    What else is not yet satisfactory: The lantern lit nicely after burning one very full cup of alcohol (about 2 min pre-heating). After a short time I noticed that altough the mantle glows fine, there's a more visible glowing aura around it compared to other lanterns I've seen. Not actually flames pushing through, but I guess it is pretty close to that. I suspect that for one reason or other, there are too much petrol fumes rushing into the mantle.


    I noticed also a small flame that busted couple of times from under the large screw that connects the carburettor ("vaporizer upper part") from the bottom to the pipe with the needle wheel assembly ("vaporzer lower part"), altough I tightened it quite firmly. The light output of thee lantern dimmed during some minutes of test burn, probably because of these leaks, nevertheless it was a rewarding experience to see the old lady in its' glory, even if not for long time.

    picture - the bubbles are coming from a microscopic hole halfway the side of the fount. Does anyone have a good tip what to do with this?


    I got an idea; perhaps I could pour about a large spoonful of liquid acrylic alkyd varnish (or something similar) into the tank and then place the tank in such position that most of the varnish will settle over the area where the almost invisible hole is, forming a hopefully strong enough cover to stop the leak when the varnish hardens. On the other hand, if the varnish will not stick properly to the brass, or will be dissolved over the time by the chemical effect of being in contact with the kerosene, lumps of it may travel to entirely wrong places and cause problems there...

  • Question Re Hipolito Lantern

    Hi Annie and welcome,


    One thing comes into my mind... Is your lantern a full-sized one (about 40cm high, the glas being 110mm x 115mm), or a smaller one? I could imagine that if we're talking about a smaller lantern, the reason for overheating might be that somebody has in the past accidentally equipped it with a nozzle that is actually meant for a larger model, and thus the lantern is now burning more fuel and respectively producing more heat than it's been designed to handle.


    According to what I've read, especially the inexpensive Far Eastern lanterns have fragile glass chimneys, so there are quality differences - but I have to emphasize that this is just a general comment - I can't say this or that about those that the suppier you mentioned provides. Anyway, a Schott glass should be a safe bet.


    By the way, my understanding is that full-sized Petromax lanterns are either 350 or 500CP but not 400CP (possibly excluding some very old an rare models) - trying to avoid to sound like a nit-picker... :)

    Still a very nice find :applaudit:

    Thanks for the compliments and lots of optimism :done:


    In one previous posting I wrote that there must be a leak in the bottom of the tank. Following a tip given in another discussion, I sunk the tank into water and found the exact spot: it was in the seam between the bottom plate and the edge of the fount. I have only a low-powered soldering iron (25W) which is not a very good tool to handle anything this big, but I succeed to put some solder over the leak, and it seems to be air tight now.


    Unfortunately I found another leak, too, and this one is in a more difficult place (at least to fix without aesthetic damage to the lantern): see the following picture - the bubbles are coming from a microscopic hole halfway the side of the fount. Does anyone have a good tip what to do with this?

    Hello, Doron,


    Here is a picture after first cleaning session. Quite a bit more shiny, but apparently the nickel coating is more or less corroded here and there, I am not sure if anything could to be done to get rid of those matt looking patches without causing more damage than good...

  • Petromax 826

    Hello,


    Your lamp looks great, and fine to see that restoring such and old one into working order is possible!


    I have earlier manged to buy a pre-war large Petromax in excellent condition
    (see http://www.pelam.de/petromaxfo…x-826,-aber-wie-alt-.html)
    but last week I found yet another one "oldie" - from closer than I could ever expect... this 821 was forgotten at my late grandparents' summer cottage, buried among abandoned stuff in a shed. A historical Petromax with a family history, not bad! It's here just in the condition as it was when found, I will start working with it when my holiday begins. I have tested that the cleaning rod and pressure pump work, but there seems to be a minor (invisible) leaking point under the tank. Unfortunately the original glass is broken. This one has a slightly different looking hood, note the smaller ventialtion holes, but there are two screws on the top like in yours (a 30´s feature, if I'm not mistaken).

  • Petromax 826, aber wie alt?

    Hallo Alle,


    (Erstens, entschuldigen Sie bitte meine rostig Deutschkenntnisse :) )


    Ich habe eine ganz interessant Petromax gefunden: diese Lampe hat viele Dekaden in Reservelager Finnischen Armee abgestellt sein, und ist 100% ungebraucht. Ich glaube das die folgende Details wink das sie von Ende 30er oder Anfang 40er Jahre ist, aber kann jemand noch meine Schätzung konfirmieren:


    - vertikale Luftschlitze
    - 2-teilige (schwarz/rot) Bakelit(?)-Handrad ohne Nase
    - Knickvergaser
    - metallische Pumpenteile und Füllschraubdeckel mit mit Flügeln, die alte Entlüftungsschraube
    - logo mit "EG"
    - Mischrohr ohne Schraube
    - es gibt ein "Schützplatte" in der Innenmantel in zwishcen das Mischrohr und der Tonbrenner


    Andere interessante Detail: Der Tank ist aus Messing, aber die Tragegestell ist aus magnetisch Material gebaut (die Hut ist nicht magnetisch, ausser oberstes Ende) und schwarz gemalt. Ich denke es ist karakteristich für ein Vorkriegslampe, aber vielleicht ist es möglich das ein untypisch Ausführung für Export/Sonderbestellung hätte solche Spezialitäten. Es gibt keine Typenschild, oder keine Marken das ein solches einmal war da. Das Glas ist definitiv nicht Original.


    Viele Danke für alle Information ich habe aus diese grossartige Seiten gefunden!
