The "Ideal" way to brew coffee...

...back in the early 1900's, anyway, was with the "Ideal" Coffee Pot.

Quite a difference a hundred years makes. And as we found out from Jitterbuzz, the "TACUCo" stamp was used from 1901-1925. This pot's stamp...

...adds its patent date as June 10, 1902. It's 10" tall and 6" at the base, about 8 cups. It has an odd filtering system, consisting of two perforated cylinders that fit one inside the other.

The larger (and shorter) cylinder has a lip that rests on a corresponding ridge inside the pot that keeps it about 1/2" off the bottom of the pot. It's also closed at the base, whereas the smaller (and longer) cylinder is open-bottomed.

I was fortunate enough to find instructions to this thing. Ground coffee is place between the two cylinders, and boiling water is poured into the smaller one. Once filled, the pot is placed "where it will keep hot (but not boil) from three to ten minutes (not more than ten minutes)". I reckon that means you could keep it over very low heat until the brewing time is complete.

The only reason I haven't used it yet is I don't want to make a full 8-cup pot.
