Improvements in Apparatus for Heating Water, and for Warming
Greenhouses and other Structures and Apartments.
I, ALFRED FOSTER, 182 York Road, Battersea, London, S.W. Foreman
Ironplate Worker, do hereby declare the nature of this invention to be as
follows:-
:-
Although my improved apparatus is intended primarily for heating greenhouses,
it is equally adapted for other structures and apartments.
1 carry my invention into effect in or in about the following manner. I provide
a coil of piping of suitable diameter and length and supported on legs or in any
other convenient manner. Each end of the coil is closed. Near the upper end of
the coil is a funnel opening into the coil. Below the lower end of the coil is a
beating chamber containing a paraffin or other lamp or a gas jet or other heating
power. Above the lamp or the like and about half way up the heating chamber is
a shallow boiler of rather less diameter or length and breadth than the heating
chamber. At the top of the heating chamber is another shallow boiler which may
be equal in diameter and length and breadth to that of the heating chamber. The
interiors of the two boilers communicate by means of a vertical tube the upper end
of which opens into the under part of the upper boiler and the lower end into the
upper part of the lower boiler. A pipe also connects the upper boiler with the
lower end of the coil. Another vertical pipe is also provided and the upper end of
this opens into the funnel already mentioned and passes watertight through the
upper boiler in the heating chamber and opens at its lower end into the upper part
of the lower boiler. The lower part of the coil is provided with a draw off cock
and the door of the heating chamber is furnished with a mica covered opening to
facilitate regulation of the lamp or jet. The apparatus is set in action in the
following manner. Cold water is poured into the coil (by means of the funnel
attached to the upper end) until it covers the end of the vertical pipe which opens
into it (the funnel). The lamp or gas jet in the heating chamber is then lighted
and in a few minutes the water expanding in the lower boiler is forced up the pipe
into the funnel and circulates through the coil and pipes as long as the heat is kept
up and in due course the water reaches boiling point.

Improvements in Apparatus for Heating Water, and for Warming
Greenhouses and other Structures and Apartments.
I, ALFRED FOSTER, 182 York Road, Battersea, London, S.W. Foreman
Ironplate Worker, 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:-
My invention relates to apparatus for heating water and for warming purposes,
and although more especially intended for heating greenhouses, is equally adapted

page_text: for use in other structures and apartments. In carrying my invention into practice
I proceed substantially as follows;-I provide a coil of piping of suitable diameter
and length and supported on legs or in any other convenient manner. Each end of
the coil is closed. Near the upper end of the coil is a funnel opening into the coil.
Below the lower end of the coil is a heating chamber containing a paraffin or other
lamp or a gas jet furnace or other source of heat. Above the lamp or the like and
about half way up the heating chamber is a boiler of rather less diameter or length
or breadth than the heating chamber and preferably shallow in depth. At the top
of the heating chamber is another boiler (also preferably shallow) which may be
equal in diameter or length and breadth to, and form part of, the heating chamber.
The interiors of the two boilers communicate by means of a vertical tube the upper
end of which opens into the under part of the upper boiler, and the lower end into
the upper part of the lower boiler. A pipe also connects the upper boiler with the
lower end of the coil. Another and vertical pipe is provided the upper end of
which opens into the funnel already mentioned, and passes on its way watertight
through the upper boiler in the heating chamber and opens at its lower end into
the upper part of the lower boiler. The lower part of the coil is provided with a
draw off cock, and the door of the heating chamber is furnished with a mica
covered opening, to facilitate regulation of the lamp, jet or equivalent.
The apparatus is set in action in the following manner. Cold water is poured
into the coil (by means of the funnel already mentioned) until it covers the end of
the vertical pipe which opens into it (the funnel). The lamp, gas, or furnace in
the heating chamber is then lighted and in a few minutes the water expands in the
lower boiler and is forced up the pipe into the funnel and circulates through the
coil and pipes, so long as the heat is kept up, and in due course the water reaches
boiling point. The heating chamber may be provided with a furnace for the
consumption of any suitable fuel, instead of employing a lamp or jet.
In order to more fully describe my invention I make reference to the
accompanying drawings which represents a longitudinal section of an apparatus
made in accordance with my invention.
a is the coil; the supports; c the heating chamber; d lower boiler; e upper
boiler; pipe leading from d to e; g funnel; pipe connecting d and g; i pipe
connecting e and lower part of coil; ; draw off cock. Safety valves and other
fittings may be provided if required. The various parts may be made of sheet or
case metal or a combination thereof as may be deemed most suitable for the purpose
for which the apparatus is used.
. I do not restrict myself to the precise shapes, configuration, relative proportions
or disposition of parts, as shown in the drawing or described in the above
specification, as they can be considerably varied without departing from the spirit
of my invention.
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 ;-
An apparatus for heating water and for warming greenhouses and other
structures and apartments the said apparatus consisting essentially of a coil and a
heating chamber the latter containing above the heating surface two boilers, the
lower one communicating by a pipe with the upper one; the said upper boiler
having a pipe connecting it with the lower part of the coil, and the said lower
boiler having a pipe connecting it with a funnel attached to the upper part of the
coil, the whole substantially as described in the above specification, and exemplified
in the accompanying drawing.
