Kemp & Co Kemp's Coil Machine - What is it's purpose?
Hi everyone I picked this coil up today, I like the look of it and think it must have quite some age to it but I don't know what it would be used for. It was completely covered in dust as it had been stored in a sandblasting place but cleaned up very nicely.
It's marked Kemp's Coil Machine on one plate and Kemp & Co Makers ........ (Can't read the location unfortunately). I'm thinking it's possibly medical? I really don't know. If anyone can tell me anything about the company that would be great too I can't find anything through Google. I've attached a few photos, apologies for the slightly poor quality the lighting wasn't great. Thanks in advance, Cameron |

Re: Kemp & Co Kemp's Coil Machine - What is it's purpose?
It looks like a classic induction coil, Ruhmkorf coil. I built a number of these in my mid teens. I had an old ( 1888 ) book on Electricity and Magnetism which gave details.
If you google Ruhmkorf there are some youtube videos featuring such coils. They were made for medical use, and general amusement ( do not try this at home ). When I was a student at Southport Tech' 1954 - 1957 there was an enormous Ruhmkorf coil in the physics lab. The coil was about 18 - 24" long and 8" diameter. They need a high current source say 12 v DC. This coil ran off a car battery and the secondary could produce big fat sparks about 8" in length.

It does seem to be a medical coil, they were popular from the late 19th Century well into the 20th Century, used to treat various conditions paralysis being one.

Sounds like it could be interesting to have a play around with, I will try to ignore the temptation.

There would have been a damper rod inserted into the coil to control the energy of the output.
