New or Improved Means for Generating Gaseous Products of
Combustion under Pressure, for Operating Engines or for other
purposes.
We, EVERARD HESKETH, of Beachcroft, Eltham, in the County of Kent,
Engineer, and ALEXANDER MARCET, of 3, Cresswell Gardens, South Kensington,
in the County of London, Engineer, do hereby declare the nature of this invention
to be as follows:
-
This invention has for its object to provide new, or improved, means for gener-
ating gaseous products of combustion under pressure, (principally intended for
operating engines, but applicable also to any other purpose for which they may
be used) from coal-gas and air, or oil-vapour and air, or other equivalent com-
bustible mixture of like nature, in such manner that, when used for obtaining
motive power for example, the said mixtures are utilized more economically than
has hitherto been possible, and so that engines, like ordinary steam engines, as far as
regards their general construction, can be employed for operation by the said gaseous
products of combustion without injury to the said engines, and so that they can
be manipulated for varying speed and for reversal, as readily as can ordinary
steam engines. According to my invention the constituents of the combustible
mixture are supplied separately, (so as to prevent danger of back-firing), under
pressure to a closed vessel, so that, immediately after admission to the said closed
vessel, they become intimately mixed to constitute the combustible mixture which
is ignited. The said constituents are preferably forced into the interior of a
hood, or inner chamber, of refractory material, perforated at its lower sides to give
communication with the interior of the said closed vessel. This hood becomes
incandescent and insures the ignition of the combustible mixture. The tempera-
ture of the products is modified by injecting water thereinto, the said water being
preferably first passed through a jacket surrounding the lower part of the said
closed vessel it then passing through a pipe, or passage, into the interior of the
said closed vessel by jets, or nozzles, projecting into the interior of the vessel.
The products resulting from the ignition of the fuel and the decomposition of the
water can be passed directly to the engine, or place of utilization, or into a
receiver in which they are stored at any desired pressure; and they will be at a
temperature at which they can be safely employed in an engine resembling for
example an ordinary steam engine.

We, EVERARD HESKETH, of Beachcroft, Eltham, in the County of Kent,
Engineer, and ALEXANDER MARCET, of 3, Cresswell Gardens, South Kensington,
in the County of London, 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:-
This invention has for its object to provide new, or improved means for gener-
ating gaseous products of combustion under pressure (principally intended for
operating engines, but applicable also to any other purpose for which they may
be used) from coal-gas and air, or oil-vapour and air, or other equivalent com-
bustible mixture of like nature, in such manner that, when used for obtaining
motive power for example, the said mixtures are utilized more economically than
has hitherto been possible, and so that engines, like ordinary steam engines, as far as
regards their general construction, can be employed for operation by the said gaseous
products of combustion without injury to the said engines, and so that they can
be manipulated for varying speed, and for reversal, as readily as can ordinary
steam engines. The accompanying drawing represents in vertical section in
Figure 1 and in horizontal section in Figure 2 an apparatus for carrying this
invention into effect. According to this invention the constituents of the com-
bustible mixture are supplied separately (so as to prevent danger of back-firing)
under pressure through the passages ab (the passage a being for gas and the
passage b for air for example) to a closed vessel A, so that, immediately after
admission to the said closed vessel, they become intimately mixed to constitute
the combustible mixture which is ignited. The said constituents are preferably
forced into the interior of a hood, or inner chamber, C, of refractory material,
perforated at its lower sides at c to give communication with the interior of the
said closed vessel A. This hood C becomes incandescent and insures the ignition
of the combustible mixture. The temperature of the products is modified by
injecting water thereinto, the said water being preferably first passed through
the pipe d and through a jacket D surrounding the lower part of the said closed
vessel A, it then passing through a pipe, or passage into the interior of the
said closed vessel by jets, or nozzles d³, projecting into the interior of the vessel A.
The products resulting from the ignition of the fuel and the evaporation of the
water can be passed directly by the pipe E to the engine or place of utilization,
or into a receiver in which they are stored at any desired pressure; and they will
be at a temperature at which they can be safely and economically employed in an
engine resembling for example an ordinary steam engine.
The passages are provided with suitable valves not shewn, for controlling the
ways for the air, gas and water and the outlet for the products.
The closed vessel A is provided with a door not shewn to enable the burner to
be ignited at first start off. Or the inverted inner chamber may be dispensed
with and the chamber A be lined with refractory material and the gas and air
be ignited therein and the products of combustion at high temperature and high
pressure be passed into a vessel containing water and so that the said products
pass through the said water thus generating a mixture of steam and gases under
high pressure and under moderate temperature as described. The water vessel
can be fitted with a gauge glass, like an ordinary boiler. The large body of water
will act to steady or regulate the pressure when the passing off of the products
fluctuates.

page_text: Having now particularly described and ascertained the nature of this
invention and in what manner the same is to be performed we declare that what
we claim is: -
1. An apparatus for generating gaseous products of combustion under pressure
the said apparatus consisting of, or comprising, a closed vessel and means for
supplying separately thereto, and under pressure, the constituents of a combustible
mixture, and means for injecting water into the said closed vessel; substantially
as herein before described.
2. An apparatus for generating gaseous products of combustion under pressure,
the said apparatus consisting of, or comprising, a closed vessel and a perforated
hood, or inner chamber covering separate inlets for supplying, separately under
pressure, the constituents of a combustible mixture, and means for injecting water
into the said closed vessel; substantially as herein before described.
3. An apparatus for generating gaseous products of combustion under pressure,
the said apparatus consisting of, or comprising, a closed vessel and means for
supplying separately thereto, under pressure, the constituents of a combustible
mixture, and a water jacket surrounding the said closed vessel and communi-
cating with nozzles projecting into the said closed vessel; substantially as here-
in before described.
4. An apparatus for generating gaseous products of combustion under pressure,
the said apparatus consisting of, or comprising, a closed vessel and a perforated
hood, or inner chamber covering separate inlets, for supplying, separately, under
pressure, the constituents of a combustible mixture, and a water jacket, surround-
ing the said closed vessel and communicating with nozzles projecting into the
said closed vessel; substantially as hereinbefore described.
5. An apparatus for generating gaseous products of combustion under pressure
the said apparatus consisting of, or comprising, a closed refractory lined vessel
and means for supplying separately thereto and under pressure the constituents
of a combustible mixture and a vessel containing water so connected with the
first named vessel that the products of combustion pass through the water before
they issue from the vessel for use.
