The position of the intermediary tube plate in the for-ward barrel is easily distinguishable by the second row ofrivet heads. The great antiquity of this invention, as alsoof the U bent smoke-tube superheater, will be understood fromthe fact that this form of superheater figures incidentally—as would achimney or a firebox in a locomotive boiler—in the French patent ofEmorine, No. 13246, April 2, 1853.
