Americus was originally from Kentucky and lived for years living in Chicago, Illinois.
In June 1902 he received a patent for the window envelope. It was first referred to as the "outlook envelope". To form the window, very thin rice paper was first used, later replaced by clear plastic. This allows the inside address to then serve as the outside address for mailing. The plastic window is also referred to as a patch.
Americus leased the patent to the Envelope Company of Springfield, Mass., which began its manufacture in July 1902.
