Hi all here is a 1051 Primus from 1950 (AO 17) What is the 17 for ? first of july ? The lamp seems to be complete but needs a bit of cleaning, so I am dismantling with care because this old lady's construction is unusual for me. here is where I am. I want to separate the collar and the fount but I don't know the manner. The fount is nickel plated and the collar is tin plated I think. This don't need the same cleaning treatment. I don't want to damage. Any help would greatly be welcomed.
Bonjour Michel, nobody knows what the number means, there are many guesses but no answers! (stoves also have the letter & a number in a circle, same problem!). Nice project, I don't know anything about Primus lanterns but this one seems to work on petrol (essence). Good luck! Bien à vous, Wim
Thanks Wim I think swedish collectors are going to give me the solution for this gasoline lamp and we'll see this old lady running soon ;-) Michel
Hello Michel, That is a very interesting lamp, the preheater and external pump give it a look all it's own. With the stamping on the frame there should be no doubt as to which fuel to use, pure genius. I look forward to seeing the progress on this one.
1051's are very good lanterns. I really like those gentle flame preheaters. To get the globe rest and collar off, it's just to continue where you are considering your pictures above. You have already managed to pry that little aluminium disc out and removed the nut hidden under it. Both control spindles and their boxing nuts must be removed, of course. I grabbed a readily available spare parts lantern to illustrate the remaining steps. From your last picture, you just need to separate the globe rest from the collar. They do stick together, but press them firmly apart, and you will be left with this: Then you need to gently squeese the collar slightly oval in order to get it past the main valve casting, as seen here: The rest is easy!
Nice illustration Christer, I love the Primus lanterns. Michel your one looks to be in great condition, nice find. Did it come with the original glass?
Unfortunately, the glass is broken. Thanks Christer, Now I need to clean neatly the old fuel and dirt. have a good day
It's a terrific little torch David. Soft and gentle, but it's all that's needed for the short period of preheating needed on a petrol vapouriser. Here's from mine in the gallery: Perhaps yours has a slightly enlarged orifice, Michel. It's a bit too yellow, but the function is still there. Time to post this lamp in the gallery, perhaps? Don't forget the before pictures if you do.
Hi Christer Carisson Wish you are good. I found the Primus 1051 in my granddad's house recently and I love this lamp very much. I want to clean this and am trying to separate the collar and the fount, but it is very difficult and I don't know how as I already go to the last step as per your helpful advice. I have actually removed the main flame spindle (yellow part) and unscrewed the two nuts (red parts), but the problem is I still can't remove the small light spindle in green as on the picture... Does anyone can please tell the way to remove this part in order I can separate the collar and the fount. Many thanks in advice
Tony, that lever is attached to the spindle with a taper, so it will sit pretty tight. You need to get it straight out from the spindle. I usually do this with a pair of common polygrip pliers, but any tool with parallel jaws will do the job. You need to have the nut still on the threads, but it should of course be loosened a little bit. But just a little bit! Otherwise the small threaded part can get bent since the force when not using a real puller always will be a bit askew. They can sit very hard, so just feel it out at first. To heat the area of the lever that sit on the taper is never wrong. And you can always try some penetrating oil, even if that seldom does anything at all to things mounted on a tapered surface. But it feels good... I think you get my point best by the picture below. If you can manage to use two pair of pliers opposite of eachother, it will of course be better, and achieve a more correct, straight force. A tiny puller would of course be the absolutely best... Here's what the tapered spindle look, once the lever is removed:
Thanks very much for your help Christer and thanks for the detailed information with the pictures attached for my easy reference. I finally made it and is cleaning the collar now. Cheers
