Soldier's copper coffee pot, in two pieces - base and upper half. The inner section of upper half is stamped: 'Patent Kin-Hee Quick Pot'. Circa 1900 USA.

In 1900, Charles Lewis was granted a United States patent on an improved reversible filtration coffee pot known as the Kin-Hee. This pot has since been further improved, and the patent rights sold in several foreign countries. It employs a filter cloth in place of the metal or china strainer used in the French drip pot.

This coffee pot is said by the donor to have been used by troops in World War One.  According to the book "All about coffee" by William Harrison Ukers, published by the New York The Tea and Coffee Trade Journal Co in Toronto,  the 'Kin-Hee Quick Pot' was made in the U.S.A. circa 1900 onwards to produce filter coffee. It was patented by Charles Lewis as an improved reversible filtration coffee pot.

The Bersten Antique Coffee & Tea collection, Queensland, notes that a cloth filter was fastened over the upper section which was then connected to the base and the whole pot upturned. Their collection holds four examples, made in copper, tin and pewter.  This coffee pot may come from American troops who entered World War I on the side of Britain and Allied countries in April 1917.
