Unic number 2 burner

Hello Gents,

I've had the opportunity to purchase a Unic #9 wall lamp, My first French lamp
It's coming from France and had been electrified so I've got some work to do once it arrives; and I will have many questions.

I found this picture of the lower burner on David's lamp.



Does this assembly come apart any further or is it one solid piece of brass? Minus the air tubes of course.

Thank you,
John

 

you can disassemble all the parts, no problem.
heat a little and knock gently, then turn anticlock

 

Michel is right but remember that: what comes loose doesn't mean it will get together well again.
When it is not broken don't fix it. Threads and parts are burned into each other.

 

Thank you both for the replies, I wondered if these suffered from the same heat related thread ailment as Tilley burners.

The good news is that it's now a possibility that the tube was unscrewed from the upper housing and then disposed of leaving the housing unmolested

One way or the other it looks like I'll need to get a new tube and mantle holder turned out of brass, are the threads on these a standard thread or some special pitch for Unic?

 

The shiny new air intake was made for me by another member here. For engineering reasons, the design was simplified into a one-piece tube without a removable end so for dismantling and re-assembly the whole tube has to be unscrewed from the burner body. I wasn't particularly concerned about this compromise because the lamp is mainly for display and might be lit only once or twice per decade.

I have a NOS mantle for this lamp, complete with the bayonet-type mounting ring but I don't intend to use it. Instead, when I lit the lamp I just tied on a suitable bag-type mantle onto the burner. This worked OK but after a few lightings, the three burner pegs eventually pushed through the mantle. I did think of having a mantle-ring fabricated from brass and then a mantle could be tied onto that but it hardly seemed worth the bother in the end.

Given I'm, having to downsize my collection and the foreign stuff is going first, my lamp could be for sale if anyone's interested. Here's the original thread:-

as far as I know, the threads are standard but French standard is metric

 

Metric is standard

How long has the metric system been the standard in France? I don't have any idea how old this lamp would be,

 

At a guess a bit over 200 years. Napoleonic for sure. ::Neil::

 

the metric system date of the French Revolution in 1790 and 1795, but I seem to remember that it was adopted by Great Britain around 1965 mainly because of difficulties in commercial exchanges.

it is difficult to date an Unic 9 because those lamps have been produced during a long time from the 30/40 to the end of the 60's
there is an old model of the Unic 9 which dates of the 30's
see this lamp.

 

Erm! actually metric came into the U.K engineering scene in 1972,or at least that when it was first taught in colleges as a standard unit of measurement ,
It had been used many years before that in many u.k industries like Motorcycles

 

Hi John

I made David's air tube but I can't for the life of me remember what thread it was ( it was a few years ago now ) , I'd be surprised if it was a metric thread, and I can't even remember if it was screwcut or threaded by die

Pete Sav posted sometime back how he made one of those bayonet fittings, search his posts and I'm sure you'll find it.

Wish I could advise you more John

Best of luck

Cheers

 

However you did it, Ray, it's a perfect fit!

 

Found it Here

 

Thank you for the link Ray, it will come in handy.

The one picture I have of the actual burner is awful so I'll post a better one of it in a fettling forum post once it arrives.

I'm hoping that it simply unscrews from the upper portion of the burner and that the the threads are still there If not we'll cross that bridge when we come to it.

Michel,

No grapes on this one so it's probably going to be of later production, still older than me though

I've seen pictures of both the aluminum and steel burner housings, mine is steel. Were these produced at the same time or as a cost cutting measure later in production.

 

the oldest are enameled steel, without enameled shades (as Unic 7 for exemple) the youngest are aluminium made with aluminium shade.

all parts can be unscrewed

 

Excellent, thank you all.

 

We'll await your pic then John

Cheers

 

The lamp arrived today

My six year old daughter saw the box and immediately decided that it was to be wrapped up and that daddy could play with it after Christmas; now how can one argue with that?

I managed to convince her that I needed to check it for shipping damage first, you know since it had come so far.

Here's my general impression of the electrocution attempt.

The tip cleaner is missing but the threads are there and thanks to this site I have a picture so I can get another made



The very tip of the burner body has been cut, from the looks of it the tube wouldn't unscrew so they just hacked it off close.



From the top side you can see that there are still threads left there too, I'll just need to remove the stub with a bit of heat and quench before building a replacement.



It's time to wrap it up now so I'll see you guys after Christmas.

 

Put a brick in the box, let her wrap that up and then you've still got the lamp to play with.

 

Or less deviously, just remove the parts that need fettling and let her help you re-box the rest. Then you can get the machining done over the next few weeks and it'll all be ready for you in January. Simple...

 

A good story John!
