Entirely by accident I stumbled upon a mention of a patent issued to Henry Waterman of Brooklyn, New York. It dates from the 1888 and is for the design of a coal burning stove.
It would seem that this would have to be Henry, Sr. rather than the proprietor of the stove company which was active some 40-50 years later.
