Improvements in Gas or Vapour Burners and Generators for
Heating Purposes.
We, HENRY ALONZO HOUSE, Senior, HENRY ALONZO HOUSE, Junior, both
of the Orleans Boat House, Teddington, in the County of Middlesex, Mechanical
Engineers, and ROBERT RINTOUL SYMON, of 20 Abchurch Lane, in the City of
London, Gentleman, do hereby declare the nature of the said invention and in
what manner the same is to be performed to be particularly described and ascer
tained in and by the following statement, reference being had to the accompanying
sheet of drawings and to the letters and figures marked thereon, that is to
say:―
This invention relates to gas or vapour burners and generators for heating
purposes, such as for the generation of steam in steam boilers, for motive power
purposes, for cooking and such like.
In the drawings hereto annexed
Figure 1 is an elevation of a burner and generator constructed in accordance
with the invention, Figure 2 a corresponding sectional elevation, Figure 3 a plan
of the burner, and Figures 4, 5 and 6 sectional plans of same taken on lines 1-1,
2-2 and 3-3 respectively of Figure 2.
Figure 7 is a sectional elevation showing a slight modification of the burner
shown in Figure 2, and
Figure 8 is an elevation of the generator looking from left to right in Figures 1
and 2.
A is the metallic body of the burner made in one piece as shown in Figures 1
and 2 or, if preferred, in several separate pieces screwed or otherwise connected
together. B is a chamber formed at the lower part of the body A and having an
opening closed by a screw plug C or otherwise. D is an inlet passage for the
admission of gas or vapour to the chamber B from the generator M or any other
available source of gas or vapour. E is a nozzle leading the gas or vapour from
the chamber B into the gas and air combining chamber F which is provided with
a series of holes G round its base for the admission of atmospheric air. H is a
third chamber also provided with holes I round its base for the introduction of a
further supply of atmospheric air. This third chamber H terminates in a kind of
nozzle or chimney J at the top of which the combustion of the mixed gas or vapour.
and air takes place. The top of the nozzle E is closed with a valve K the upper
part of which is carried upwards in a conical shape as shown in order to form the
upper part of the chamber F as an annular passage. The valve K is weighted by
a weight L or, if preferred, by a suitable spring, so that the gas or vapour entering
the chamber F can only do so by raising the valve K and weight L and this
requires the gas or vapour to be delivered at such a pressure that it escapes round
the valve K, when the latter is raised, at such a velocity that it induces an inrush
of atmospheric air through the holes G. This air mixes intimately with the gas
or vapour and the mixture rushes with considerable velocity into the chamber H
and induces a further inrush of air through the holes I; this air mixing with the
air and gas or vapour coming from the chamber F produces a mixture which
burns with an intense heat at the nozzle or chimney J.
It will be understood that the weighted valve K gives a constant pressure to
the gas or vapour whatever quantity may be passing through the nozzle E.
In some cases either or both of the chambers FH may be dispensed with the
lower part of the burner including the chamber B and nozzle E and weighted
valve K only being retained. And it is sometimes convenient to arrange for

page_text: the upper part of the body to be connected to the lower part by a screw
thread A as shown in Figure 7 so as to enable the parts to be separated for
cleaning and repair.
As above stated the gas or vapour supplied to the burner may be taken from
any available source of supply such as a gasholder suitably weighted to supply
the gas or vapour at the required pressure, a vessel containing compressed gas
or vapour, or directly from a generator in which gas or vapour is produced from
a hydrocarbon liquid, as for example from the gas or vapour generator M. This
generator is placed immediately over the burner A so as to be heated thereby
and is constructed as follows:-
M is a disc of gun-metal, iron, steel or other suitable metal or material of an
inverted saucer or bell form provided with a hollow space or chamber M¹ prefer-
ably but not necessarily filled with asbestos or other suitable incombustible and
more or less porous material through a hole in the top which is afterwards closed
by a screw plug M². N is a pipe for conveying the hydrocarbon liquid in regulated
quantity from an overhead tank or other source of supply not shown in the
drawings under sufficient pressure. P is a pipe leading from the upper part of
the hollow space M¹ in the generator to the inlet passage D of the burner A
placed below. Q is a passage leading downwards from the hollow space M' into a
conical projection R and terminating in two fine holes S S.
The action of the generator is as follows:-
Hydrocarbon liquid is admitted into the hollow space M' through the pipe N,
the supply being regulated by means of a tap or valve in the said pipe (not shown
in the drawings and heat is applied to the underside of the generator, especially to
the conical projection R, by means of a spirit lamp or otherwise. This vaporises
a portion of the hydrocarbon in the hollow space M' and a part of the gas or
vapour issues at the holes S S and ignites on contact with the flame of the lamp;
the lamp may then be withdrawn and these burning jets of gas or vapour continue
the heating of the underside of the generator M and the consequent vaporisation
of the hydrocarbon liquid supplied to the hollow space M. Part of the gas or
vapour thus produced continues to supply the jets at S S but part thereof passes
by the pipe P to the burner A and when this gas or vapour is ignited at the nozzle
or chimney J the flame impinges upon the underside of the generator M and a
part of the heat is expended in vapourising or gasifying the hydrocarbon liquid
supplied thereto in regulated quantity by the pipe N, this vapour or gas then
passes to the burner by the pipe P and is there mixed with air in the manner
before described, the mixture being heated in the chambers F and H before
combustion by the heat communicated to the body of the burner from the
burning gas or vapour. The part of the heat of the flame not required for
vaporising or gasifying the hydrocarbon liquid is available for any heating purpose
required, such as that of raising steam in a steam boiler, for cooking, and so forth.
When the burner A is extinguished a very small supply of hydrocarbon liquid
to the generator keeps the two jets S S burning and these act as pilot burners to
ignite the mixed gas or vapour and air at the burner A when the supply of hydro-
carbon liquid is increased sufficiently to supply gas or vapour to it.
It will be understood that the generator M above described may be used in
connection with any other suitable burner instead of the burner A such as an
ordinary "Bunsen "burner for instance.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
First. In a gas or vapour burner, a gas or vapour chamber B, & nozzle E and a
weighted or spring-urged valve K combined, arranged and operating substantially
as described with reference to the annexed drawings.
Second. In a gas or vapour burner, a gas or vapour chamber B, a nozzle E, a

page_text: weighted or spring-urged valve K, and an air and gas or vapour combining
chamber F having air inlet holes G, combined, arranged and operating substantially
as described with reference to the annexed drawings.
Third. In a gas or vapour burner, a gas or vapour chamber B, a nozzle E, a
weighted or spring-urged valve K, an air and gas or vapour combining chamber F
having air inlet holes G, and a second air and gas or vapour combining chamber H
having air inlet holes I and a nozzle or chimney J, combined, arranged and
operating substantially as described with reference to the annexed drawings.
Fourth. The improved gas or vapour generator which consists of a disc M, a
hollow space or chamber M preferably but not necessarily filled with asbestos or
other suitable incombustible and more or less porous material, a pipe N for the
admission of hydrocarbon liquid to the hollow space M', and a pipe P for con-
veying the gas or vapour from such hollow space to the burner, combined and
arranged substantially as described with reference to the annexed drawings.
Fifth. The combination of the improved gas or vapour generator consisting of
the disc M, the hollow space or chamber M¹ and pipes N and P with a heating
burner of any suitable construction placed below the said generator, substantially
as described with reference to the annexed drawings.
