I have recently tracked down a few of the early patents that are stamped into the bottom of some of the Manning Bowman percolators. There was a total of six US Patents that were issued and assigned to Manning-Bowman between 1904 and 1906. I will list the most referred to patents first. 

The Nov. 8, 1904 U.S. Patent Number 774,278 is referred to extensively when people write their description, but most people are unaware of what this patent describes. This was the U.S. Patent for the Alcohol Lamp that was used to heat the pot.

U.S. Patent Number 751,565 issued February 9, 1904 is a very significant coffee patent. This patent describes the basic percolator bell that fits on the bottom of the coffee pot. Ever seen a Pyrex coffee pot?
