    Hi, I am working on a Blachard wall lamp model 850,150 CP.
    This lamp has no shut-off option. In pictures I have seen but that lamps of this type have something. Am I doing something wrong ? What does the glass look like and what dimensions does it have? How is it fixed? Does someone from the round pictures of it?
    Answers to my questions would help me a lot.
    I wish you all a nice evening with lots of light

    I think the pricker acts as the shut off.

    There is a some thing at the top of the glass though :-k

    If the gallery is with the lamp you have, you can answer those two questions by observing and measuring.

    Hello Roland,

    The glass is a similar size and shape on some Hasag lamps,
    HASAG 65 Wall lamp


    Perhaps @karli can help you.

    I think these images will show how the glass fits into the lamp.

    I made one from 3mm wire and the inside diameter of the ring is 106mm.

    Henry.

    Blanchard wall lamps normally don't have a shut off valve. You shut the lamp off by releasing pressure. Blanchard burners are difficult to work with because they are so very different to any other types and require some special tools to remove the jet and release the pricker shaft spring. Actually simple enough once you work on a few though and they do work very well. Designed in 1909 and never changed but some of these 100 year old burners give an amazing light.

    All Blanchard lamps are hard to find and a lot of collectors never manage to find one. However there are a few of us who have several and have made them work. Getting the pricker to work correctly can be tricky if you need a new needle as these are long obsolete but you can make a needle. I do this by grinding a new tip on a piece of an old Tilley pricker wire. Tilley wire is the right size to fit the needle holder in a Blanchard and grinding down to 0.006" is simple enough.

    Neil.

    @Mackburner is it possible to know some more about how you grind to 0.006" please?
    I would have no idea where to start!

    I fix a piece of Tilley pricker wire in a dremel and take off the bulk using a file in a vice and then take it down to 0.006" with a small hand held oil stone. The Dremel runs faster than a drill so is better for dealing with small diameter stuff. Not tried with a drill and a hand held abrasive. Anthony's method might give better control and I will give it a try next time I want a pricker grinding down. ::Neil::
