Coffee brewing 50’s style

These brewing machines are incredibly durable.
The other day I discovered a wall-mounted two-pot coffee brewer built by the Württembergische Metallwarenfabrik WMF.
It still works like a charme and brews excellent coffee!

What a beauty!


This thing is directly connected to the house‘s water tubing.


The lamp is on and soon the very essence of a satisfactory life will start dripping into the stainless steel pot below.


Here comes the coffee!


I did a bit of research after reading that plaque. These machines were built from the mid 50ies up to the late 60‘s if I‘m not mistaken.


See that box attached to the left with that glowing switch? They told me that this is the heating element for the water and that it works with mercury.
I‘m not so sure if it really uses mercury for heating (as they implied) but that it rather has a mercury thermostat for regulating the heat.

    I wonder if it maybe has a mercury switch attached to a float in it to turn the power off when the water level gets low?
    That is quite the unit man, it looks like something you would see in a restaurant.
    Back in the 50’s here we used percolators.

      Dunno if this is related to your suggested mercury switch – but take a look at the last picture: right above that plaque you can see some little stick protruding out. It’s not a switch you could operate but it rather jumps up and down like mad while that machine does its job…
      I‘m sure they used to have such machines in restaurants, too. This one I found in a bed & breakfast pension that was built in the 50‘s.
      Percolators, huh. I just looked it up on Wikipedia. The only thing I know that’s close to a coffee percolator are these “Bialetti” Espresso makers. They work the same but they don’t cycle the brew. The water that’s being pushed upwards is also pressed through a chamber containing ground coffee and then exits trough a tube at the top where it remains.

        If that little knob jumps up and down rapidly then I would speculate that it is hooked to an electric solenoid.
