It reminds me of the acetylene lamps which were used in lighthouses, but that actual design is new to me. Lighthouse Lamps Through Time by Thomas Tag | United States Lighthouse Society
If we were voting - that would be where I would go. Is that two gas jets on the top tho ? Intriguing find..
Hi all The lamp is clean and it works But we have absolutely no idea of the usefulness of these spheres and multiple taps. They seem to have no effect on the functioning of the lamp ... mystery And as there is no registration on the lamp, it is impossible to do a patent search
If the lamp was made like that from a factory, the spheres and other stuff may be part of the safety system since you obviously have a positive shut off valve directly under the burner. Atleast Swedish regulations didn't allow a shut off valve there on regular drip lamps without other precautions to take care of the pressure remaining water could build up. (As we all know, acetylene by itself can explode with just a tiny increment in pressure. That's why we have so many regulations with carbide lamps. Like the pressure escape via the safety holes in the water compartment or the extremely coarse and tapered burner threading which allow the burner to pop out before the pressure below get critical. Just to mention some.) I have atleast a hundred carbide lamps- mainly drip lamps- but the only drip lamp I have that has a shut off valve like that is the one seen below. That one has some sort of extra volume built in to take care of residual gas formation after the valve was shut. (A double mantle around the carbide container, giving the lower part an unproportional size.) This particular manufacturer did actually bragg about being the only lamp (in Sweden during the carbid lamp era of WW1) with the drip system that has been approved to use a shut off valve under the burner! Possibly yours have similar means to get around that problem. If it actually is a manufactured lamp, and not something cobbled together afterwards.
@Carlsson thank you very much I don't know if this lamp is factory made or not Yes could be a security system, but how much complicated !!!
I think it's an old sterilizer that was used to kill pathogens using heat and pressure. Pressured steam was used to disinfect medical equipment.Microorganisms such as bacteria,viruses and fungi were to be killed.I assume that such devices were developed during the First World War.
