Hi folks, could anyone please tell me about this model of lamp? It is not like a normal protector in that it has a flat wick, and so I am led to believe is paraffin based. The strangest thing I don't understand is that it uses what appears to be high voltage to ignite the flame. The reason I say this is that there is a stud on the outside, heavily insulated from the body. The thick wire travels up toward the top of the wick holders before terminating some 6mm from the edge. There appears to be no way that a filament was ever attached here, as there nothing to connect the other end.
The problem I have is that Paraffin has a very high flash point, too high for spark ignition!
I will post some pics and a video of my attempt to ignite when I can.
In the mean time, could someone possibly give me some hints as to the correct lighting procedure, and perhaps specific fuel for this lamp?
Thanks in advance,
Olly.

The spark was supplied by a magneto. I think it was hand cranked.

ok thanks Ken, Do you know any more about these lamps then? Pity information is so sparse!

Have you been able to open the lamp? If not you may have a job. The base is locked with a magnetic lock which operates a ratchet and pall. The opening magnet was placed on the base under the insulator which pulled the pall down. If it opens already the pall has been sawn off like mine. So to light the lamp just unscrew the base and use a match!!!.
So you could use kerosene in the lamp but I don't think that is the correct fuel. It is probably smoky.

Hi Ken, original locking mechanism has been restored and the lamp has new wicks. Neodinium magnet unlocks as it should. I am just too curious and so wanted to attempt to light the lamp as it would have been originally, which I have in fact achieved but only with a touch of petrol mixed with the paraffin which I am not too happy with! Voltage to create arc is very high!!! I have actually taken the lamp underground on a couple of occasions, being a member of the DCC we look after the mines at Alderely Edge. Have to say how miners managed with this light I will never know! goo.gl/photos/G67Loev1cxgsPaDr9^^ Link to video of it lighting flame |

My experience with oil lamps extends only to the Protector make. But I doubt any oil lamp used in firedamp testing would be fueled by paraffin, I doubt you'd get a testing flame suitable to read a gas cap. The Deputy's or U/M's on the forum could correct me on that one. Fuel most common were Naptha based like "coalzaline" (sp)
Clean burning and produces the best testing flame.
We did flame safety lamps in our first year under the old five year apprenticeship in Mining Technology, but we only dealt with the Protector relightable and workman's lamps, and the Spiralarm types.

I have about 2 litres of Cozalene if anyone wants to try some, also various protecter bits and pieces.ie flints etc plus 1 home made charging unit using Oldham parts for cap lamps. I am not selling these items but if anyone is interested in making a small contribution to cancer research that would be welcome. I live near the South Derbyshire / Leicestershire county border. Contact through this site.

Hi John, thanks for your help. I tried this lamp on lighter fuel which seems the choice for protector lamps and the result was a very unstable flame! This was partly because the wide wick holder has a slot down the middle which facilitates adjustment via a claw that is controlled from the bottom. This resulted in the fumes catching light at the base and starving the wick top of oxygen. Result was that the flame would extinguish very quickly! Anyway, I had almost given up, ended up with another Patterson A1 which equally performed poorly. It was only then that someone told me these lamps were designed to run on paraffin and not fuel! They said as there is no wadding in the chamber with petroleum based fuel I potentially had a bomb!! The moment I filled with paraffin it burnt perfectly! I wondered weather these were designed for underground use except for the fact it has a mechanism to prevent unauthorized access and lighting! I would love to know more about it but information is very thin on the ground! |

I would be more than happy to make a donation too :-) |
