Hokey set-up, but I'll be danged - it works!

Update:

After researching Tuttle & Kift's patents, it turns out that little box is a filter condenser to prevent radio interference from the arcing of the switches. Which means that the infinite heat switch motor, pilot lights, convenience outlet, and automaticook timer are all on a separate 110 volt system throughout the range.

Cool. Maybe....

But, the wiring diagram I found doesn't explain the indicator lights - so will be researching those further.

Can you explain how the switch motor functions? I'm not clear as to what it does.

I don't know either at this point...

Apparently, the motor drives a cam/follower system turning the current on and off to the burner at varying times depending on the setting of the dial to maintain a desired temperature. To maintain a higher temperature, the motor turns on the burner more frequently than it would for a lower temperature. To see the actual operation, I would have to destroy the switch bank or try to follow the description in the patent. The patent drawing is quite a bit different than what I actually have so it's hard to "see" what the operation looks like. I do think that the on/off of the circut depends on how well the burner element maintains heat between cycles to keep the desired temperature. If it looses heat too quickly, there would be definite spikes between high and low. (On/off)...

Indicator Light

That's pretty cool!

I'm exhausted just reading all that without a coffee pot break

 

[davey7]

That's just pretty darn cool!

I would DEFINATELY!

Use the original switch unit! If it works that is, Now to find some original TK Monotubes!

Do I smell coffee?

For Rick, only Universal

Now to find some original TK Monotubes!

Well,

That's all very well and good Hans - but where am I going to find someone who lives in Mocksville N.C., who knows just about everything there is to know about vintage ranges and who and/or his partner has a knack at finding unused NIB treasures such as monotube range "eyes" at estate sales and well established dealers that have been in business since the 1930's?

I'm sure that I don't know anyone like that..........

Bill - very nice percolator! Three cup Puritan pattern?

Ok dear heart!

I will start Looking!!!! Tell me exactly what you need!!!
