PROVISIONAL SPECIFICATION.
Improved Heating Apparatus for Greenhouses and other Buildings.
I, EDWARD REES of 12 Union Street Swansea in the County of Glamorgan
Tinsmith do hereby declare the nature of this invention to be as follows:-
The object of my Invention is the efficient heating of greenhouses and other
buildings with the minimum amount of fuel and my invention consists of a
modification of the usual hot water apparatus.
To effect my end I carry the flue of the heating fire grate through the building
to be heated, in a convenient direction preferably in a horizontal, or nearly so, direction
some distance before it rises into the air.
This flue is made in convenient sections which can be easily joined together and
consists of a double tube, one within the other, the outter or annular space being
intended to be filled with water for the regulation of the heat. The different
sections, made so that they can be easily added to each other for length are formed
to this end in the following manner. Each section has its annular space closed at the
ends save one or two holes, while the inner tube projects either at one or both ends
and made so that one end of the one may enter one end of the next. The annular
spaces are now connected by short junction pipes at the holes so as to allow a free
passage for the water. The water space may communicate by a pipe with a cistern, to
keep it full.
Air tubes and taps aro provided to allow the escape of air in filling the water
space. The greater portion of the heat of the fuel is thus by traversing the long
length of flue communicated to the water and so to the air and thus a saving is
effected.
Dated this 21st December 1888.
COMPLETE SPECIFICATION.
Improved Heating Apparatus for Greenhouses and other Buildings.
I, EDWARD REES of 12 Union Street Swansea in the County of Glamorgan,
Tinsinith 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:—
The object of my Invention is the efficient heating of greenhouses and other
buildings with the minimum amount of fuel, and consists of a modification of the
usual hot water apparatus.
To effect my end I place my fire grate in any convenient position and from it I
carry the flue through the building to be heated in a horizontal-or nearly so-
direction to a suitable distance, either in a straight line, or round the building or
backwards close to and parallel to itself, afterwards rising and discharging into the
outter air.
The flue is made in convenient lengths which can be readily joined together in
manner hereafter shown.
This flue consists of a double tube one within the other, the outter or annular space
being intended to hold water to form a water-jacket so that the water shall absorb
the heat from the heated gases as they pass along the flue.
The different sections or lengths are made so that they can be easily added or joined
to each other for length in the following manner.
Each section or length has its annular space closed at each end so that in looking
at the end it would appear as a thick pipe, or tube having a thick wall.

page_text: The inner tube of each section however projects at one end at least, so that this
projecting end of the one may enter the other end of the next and thus build up a
continuous inner or flue tube. Holes are made in the annular coverings at the ends
and these are connected by short junction pipes so as to allow of a free passage or
circulation to the water.
The water space may communicate by a pipe with a cistern to keep it full. Air
tubes or taps are provided to allow the air to escape on filling the water space.
A greater portion of the heat from the combustion of the fuel is given up to the
water from the fact that the heated gases have to pass so great a distance along
a surface in contact with the water, the heat again passing into the place to be
heated.
Referring to the accompanying drawings Fig. 1 is an elevation of the tubes at a
junction of one section with another F. F. being the flue tubes shown at the broken
ends. G is a continuation of the flue tube entering the next section. J J are the
junction pipes between the water spaces. These may be soldered screwed or
otherwise fastened watertight.
Fig. 2 represents the end of one of the sections, the centre F being the flue W W
being the wall of the enclosed water space.
Fig. 3 represents a section through Fig. 1. The tubes may be made of sheet iron
with a seam or of cast iron. The thick lines represent a section in sheet iron.
Where cast iron is used the walls would be thicker and the junction pipes would
have screw connections. W W is the annular or water space F. F. the flue, G the
projecting portion of the one entering the next to form a continuous flue JJ the
junction tubes for the circulation of the water.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
1st. A waterjacketed flue carried into a room or house for the purpose of heating
substantially as described.
2nd. The arrangement for adding length to length substantially as described.
Dated this 6th November 1889.
