Improvements in and relating to hot water-heating Apparatus for
Greenhouses, Conservatories, and other Places.
I, ARTHUR HUXLEY of 20 Pine Street in the City of Liverpool in the County
Palatine of Lancashire Gasfitter &c. do hereby declare the nature of this invention
to be as follows:-
The chief aim in this my improved apparatus, is to utilize to its fullest extent the
Heat given off and wasted by the flue pipe. To do this I construct two Tubes or
Pipes of differant diameters, the smaller one being enclosed in the larger and secured
in a central position by means of two midfeathers running longtitudinaly ; thus
dividing the larger tube or pipe into three sections the inner section being used as
the Flue-pipe, the outer sections as the flow & return water ways respectively.
The midfeathers are made continuous with the whole length of the Tubes, with the
exception of a small space at one end to allow the water in the upper section or water
way to pass in to the lower.
The Flue pipe is now connected to the stove, and the water ways to the Boiler,
by short lengths of pipe providing, a complete circuit for the water to & from the
Boiler.
Dated this 13th day of December 1886.
ARTHUR HUXLEY.

I, ARTHUR HUXLEY of 20 Pine Street & 49 Renshaw Street in the City of Liverpool
Heating & Ventilating Engineer etc. do hereby declare the nature of this invention
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
As stated in my Provisional Specification, my cheif aim in this my improved
apparatus, is to utilize to its fullest extent the Heat given of and wasted by the flue
pipe in heating apparatus as at present constructed.
To do this I construct two Tubes of differant, diameters, the smaller one being
enclosed in the larger & secured in a central position by divisions or midfeathers
running longtitudinally thus dividing the larger Tube into three sections, the inner
section (1) being used as the flue, or escape smoke pipe, the outer sections (2 & 3)
as the flow and return water-ways.
The midfeathers (4) are made continuous with the whole length of the tubes save
with the exception of a small space (5) at the extreme end to allow the water in the
upper section to pass into the lower.
The flue pipe is now connected to the stove or furnace, and the waterways to the
boiler, by suitable short lengths of pipe (6) as may be required the upper and lower
sections of the tube are terminated and enclosed (7) at any desired point, the inner
section or flue pipe being continued on with ordinary stove or furnace pipe to where
required.
When the apparatus is in operation it will now be seen that the surplus heat not.
absorbed by the boiler is passed through the water in the upper and lower sections of
the tubes. The heated water from the boiler flows by circulation along the upper
section (2) of the tube, passes through the openings (5) at the end of the midfeathers,
and returns to the Boiler by the lower section (3) thus being kept in contact for its
whole length with the heated inner section or flue pipe (1).
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed, I declare that what
I claim is
An improvement in heating apparatus, by constructing a combined flue and water-
way pipe or tube for the purpose of utilizing the heat that would be otherwise
wasted.
And I humbly pray that letters Patent may be granted to me for the same.
