What is a Lucas Smoke Gage?

I have no clue.

I am still looking for a picture of a Lucas clock that was an option on the Bugeye.
 
Lucas Clock? or Smiths
 
When the glove box door closes on a wire & a lot of smoke comes out of your vents, the gage tells you if that bad or good. Mine always comes up bad.
 
Wasn't the Lucas voltage gage a rare bird in the late 50's
(as opposed to an amp gage)

That's my WAG
 
There is also another version that measures the quantity of smoke in the wires. As most of us know from experience, occasionally the smoke builds up excessive pressure, and forces its way out. Usually in the vacinity of corroded terminals, generators, or old switches.

Gesh, I am setting here laughing. That't kind of what I thought.

However that said I can find references all over the web on Smith Clock, repair for autos, but no pic or other data. Anyone ever seen one. Oh come on someone must have one.
 
I've seen a couple on ebay. What diameter?
 
I guess not.
 
I bet, I just bet that's it. The price is not even too bad to put on the bottom of my want list.

Thanks
 
Now you must remember that Lucas systems are based on the transfer of energy via visible ions. The theory was that the common systems based on electrons were much too difficult to troubleshoot because you can’t see an electron with the naked eye. This is why Lucas uses the Simple Monitoring Of Key Elements system or SMOKE for short. In the beginning they used negative smoke that was drawn to the positive ground of the car. This was a by far a superior system because you could always tell when the jumper cables were hooked up wrong. The problem is that it very expensive to ionize negative smoke and have it maintain its charge in inventory (hence all the jumper cables). To combat this problem they changed to positive smoke. This smoke is naturally occurring (smoke rises from a campfire, and up is positive, so were all made positive smoke when we were kids). A common misconception is that all smoke is the same color. This is not true. The color you see in the wire is actually the color of the smoke. When it escapes from the wires it oxides and turns the grayish black color that we are all familiar with. Jeff is correct in that excessive pressure will cause smoke to escape. Lucas built in pressure relief valves into their design in the form of loose connections and corroded terminals. Our attempts to correct these loose connections and corroded terminals are really just part of the ingenious design of the Lucas engineers. All relief valve systems need regular maintenance and this is their way of getting us to do it. So you see it was all planned for, and it is only those owners that don’t perform the proper PM on their safety systems that must resort to adding Genuine Lucas Smoke back to their cars.

Whoot, I had to put my feet up on the desk for that.
 
The gauge checks to see if the original Lucas smoke is still installed in your wiring. If smoke appears all is well. If no smoke appears you will have to locate where it leaked out , fix or replace the bad item, and refill your system with whatever after market smoke you can find.

Ahh, shucks and the second pic is a clock, was sure someone had one.

Now that first pic, what is that an ash tray?
 
Biff, I love your clock and am going to have one for sure.

Now, smoke gage, what is it for, where does it hook up?

It surely is an intresting item and wish I could fine one just for fun if nothing else.
