PROVISIONAL SPECIFICATION.
A New or Improved Hot Water Boiler for Warming Greenhouses,
and for other useful and similar purposes.
I, JOSEPH (OOPER of Vulcan Iron Works, Russel Street, Hyde, in the County of
Chester, Engineer, do hereby declare the nature of my said invention to be as
follows:
My invention has for its object to produce a simple, inexpensive and efficient hot-
water circulating boiler for warming greenhouses, and other buildings, and consists
essentially of a shallow and, by preference circular form of metal vessel of about ten
inches diameter, and such vessel enclosed within a hood or dome of sheet iron of any
suitable shape or design, and having openings in its sides for the entrance of the
flow and return pipes of the heating apparatus. Beneath this vessel is a Bunsen
burner, with connections to a gas supply, which on being lit, and owing to the large
area of the vessel surface and the thin layer of water, rapidly heats up the water in
said vessel, and in the said heating apparatus.
The products of combustion or fumes (if any) from this burner pass up into the
hood aforesaid, and before escaping into a suitable flue at the top of said hood, serve to
heat up the upper surface of the vessel and the pipes connected with it. These latter
are all fitted into the upper side of the vessel and are, by preference in the form of
bends which may be adapted for coupling up the pipes at various heights and angles.
The aforesaid cover may be connected with the vessel, and supported upon a suitable
base or stand to afford compactness and portability.
In lieu of heating by gas an oil lamp may be fitted to the boiler, or a special grate
or fire basket may be employed for heating the boiler by fuel, but I prefer gas as it
can be more conveniently regulated according to the temperature required.
Dated this 25th day of October 1895.

A New or Improved Hot Water Boiler for Warming Greenhouses,
and for other useful and similar purposes.
I JOSEPH COOPER of Vulcan Iron Works, Russel Street, Hyde, in the County of
Chester, Engineer, 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 has for its object to produce a simple, inexpensive and efficient hot-
water circulating boiler for warming greenhouses, and other buildings, and consists
essentially of a shallow and, by preference, circular form of metal vessel of about ten
inches diameter, and such vessel enclosed within a hood or dome of sheet iron of any
suitable shape or design, and having openings in its sides for the entrance of the flow
and return pipes of the heating apparatus. Beneath this vessel is a Bunsen burner,

page_text: with connections to a gas supply which on being lit, and owing to the large area of
the vessel surface, and thin layer of water rapidly heats up the water in said vessel,
and in the said heating apparatus. The products of combustion or fumes (if any)
from this burner pass up into the hood aforesaid, and before escaping into a suitable
flue at the top of said hood, serve to heat the upper surface of the vessel and the
pipes connected with it. And in order that my said invention shall be the more
readily understood and carried into practical effect I have hereunto annexed a sheet of
drawings shewing a vertical elevation in section (about size) of my improved
boiler, and I will now proceed to describe the same with the assistance of the
various figures and letters of reference marked thereon. (A) is the aforesaid shallow
vessel for holding the water, and forming my improved boiler. Beneath such boiler
is a Bunsen burner (B), the gas flame of which impinges against the under-side of
said boiler as illustrated, and thus serves to heat up the water,-the peculiar inverted
dish shape of the boiler being designed to direct the heat towards the centre of the
vessel. Surrounding, or enclosing the boiler is a shell and dome like casing (C) of
iron, which rests upon base plate (D) standing upon legs (D¹). Through this casing
the pipes (E) for the flow of the water, and the pipes (F) for the return of the water
pass as illustrated, the respective pipes being coupled to the boiler by bends (G), and
T piece (H) with rubber rings (C) to make the joints. The top of the casing leads
to a flue (I) for any fumes or vapour from the gas to escape through, and for producing
a current of air through the casing, for combustion and ventilating purposes.
Whilst the top of the casing (U) is shewn sloping, it may be made flat or horizontal
and arranged to carry a shallow pan or dish, or made with a fixed flange (as shewn
by dotted lines) entirely or part way round, and forming a dish or tray for holding
water, which, by the heat below, is vaporised and serves for humidifying purposes.
Owing to the peculiar shallow and disc like construction of boiler, the water within it
is presented to the heating medium in a thin sheet, and with such heating medium
acting upon the top as well as the lower side of the boiler, the water is very rapidly
heated. Moreover, the fumes and heated air passing up through the casing play
upon the pipe connections, which further serves to enhance the efficiency of the boiler.
The supply of gas is controlled by tap (J), and the temperature of the water can
thereby be regulated to various degrees. For draining the circulating pipes when
required, I provide a tap (K). A similar tap is also provided at the highest point for
allowing the air to escape when filling the apparatus. In lieu of heating by gas, an
oil lamp may be fitted to the boiler, or a special grate or fire basket for heating the
boiler by fuel, but I prefer to use gas as it is more conveniently regulated according
to temperature required.
Having thus 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 and desire to secure by Letters Patent is :-
In means for warming greenhouses, the use of a shallow and inverted dish Ele
vessel (A), in combination with a casting (C), and mounted and arranged and coupled
up with circulating pipes, and heated by gas, oil or fuel, as set forth ari
illustrated on the accompanying drawing.
