Improvements in Boilers for Heating Purposes.
We, WILLIAM GEORGE MISON, Clothier, JAMES CARPENTER, Gardener, and
ALFRED ONION NEVILLE, Tailor, all of 3, Ada Villas, Hereward Road, Tooting,
do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in boilers for use in hot houses and
for other heating purposes, and provides a boiler of this kind which will be more
effective than those at present in use.
In carrying out our invention we fit the boiler within a cylindrical casing, the
lower part of which receives a gas burner or lamp. Openings are formed in the
lower end of the casing for ventilating purposes and to allow of the insertion of
the lamp.
A.
The boiler is of conical form both internally and externally, the inner plate
forming a funnel-through which the heated air from the burner passes.
tube at the top leads this heated air into the upper part of the casing where it
escapes through a suitable chimney.
The outside of the boiler is of different form to the inside, the cone tapering
somewhat less. The lower edges thus meet and the boiler becomes gradually
thicker towards the upper end so that the main body of water is contained at its
upper part.
Pipes lead through the top of this boiler in both directions, the hot water flowing
out through these pipes and corresponding pipes are fitted at its lower end through
which the cooler water returns.
A constant circulation is thus kept up and the heat is utilised in the most
economical manner. The pipes pass out through the sides of the cylindrical
casing.
Improvements in Bollers for Heating Purposes.
We, WILLIAM GEORGE MISON, Clothier, JAMES CARPENTER, Gardener, and
ALFRED ONION NEVILLE, all of 3, Ada Villas, Hereward Road, Tooting, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
This invention relates to improvements in boilers for use in hot houses and

page_text: for other heating purposes and provides a boiler of this kind which will be mors
effective than those at present in use.
In order to more clearly describe this invention reference is had to the accom-
panying sheet of illustrative drawings on which
Fig. 1 is a front elevation partly in section showing a heating boiler constructed
in accordance with this invention an oil lamp being employed for heating and
Fig. 2 shows a double apparatus heated by means of a gas burner.
The casing A preferably of cylindrical shape is adapted at its lower part to
receive a lamp B as shown in Fig. 1 or a gas burner C as shown in Fig. 2 and
openings or c are provided to allow of the insertion of the lamp or burner and
for ventilation purposes.
The boiler D is formed of the internal and external cones d d¹. The two cones
are connected together at their upper and lower ends and the outer cone d tapers
less than the inner cone d¹ so that the space between them is greater at the top
of the boiler than at the bottom and the main body of the water is contained at
its upper part.
An opening is formed through the boiler at immediately over the lamp or
burner, so that the boiler D) forms a funnel, the heated air from the lamp or
burner passing through the said opening into the upper part a of the casing A
where it escapes through the chimney E.
Pipes or tubes F F¹ pass through the casing A and are connected to the
boiler D at f f¹. The pipes F F are suitably arranged to serve the heating
purposes required and are connected to the water container G. The hot water
flows away through the upper pipe F and thence back to the container G while
the cooler water arrives from the container G by means of the lower pipe F¹. A
constant circulation of water is thus kept up and the heat is utilized in the most
economical manner.
In the arrangement shown in Fig. 1 only one set of pipes F F¹ and one con-
tainer Gare employed but in Fig. 2 the arrangement is double there being two
sets of pipes F F¹ connected to the boiler D at each side and two water con-
tainers G.
In either arrangement a lamp B or a gas burner C may be employed or other
means for heating may be used without departing from this invention.
The chimney E is preferably formed with a downward extension e open at its
lower end by which means any down-draught occasioned by a gust of wind or
other means above the chimney is prevented from passing back to the lamp or
gas burner.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:-
(1) An improved boiler for heating purposes comprising a double cone shaped
boiler arranged within a suitable casing the outer cone of which tapers less than
the inner cone so that the main body of water is contained in the upper part, an
opening being also formed at the top through which the heated air passes to the
upper part of the surrounding casing and thence to a chimney, a system of pipes
by which water is brought to the lower portion of the boiler and taken away from
the upper portion thus setting up a circulation of water, and a heating lamp or
gas burner arranged at the lower end of the casing and below the boiler sub-
stantially as described.
(2) An improved boiler for heating purposes comprising the casing A having
opening or cat its lower end, lamp B or gas burner C, boiler D formed of the
internal and external cones d d and provided with an opening d² by which heated
air passes from the lamp B or gas burner C to the space a and thence to the
chimney E, pipes F F¹ connected to the boiler D at f and fl and a water con-
tainer Gall arranged and operating substantially as described and for the pur-
poses specified.
