I FRANCIS WINDHAM of 124 Cheyne Walk Chelsea London S.W. Engineer do
hereby declare the nature of this invention to be as follows:-
The Invention has for object improvements in an apparatus or Generator in which
carbon or hydrocarbon is vapourized by the heat of its own combustion under pressure
and mixed with oxygen, the resultant gases being used in an engine as a motive power.
In an apparatus or generator according to this Invention, there are employed, an
incandescent grate, or filter, a combustion chamber, a vapourizing chainber, feeding
and clinker doors, a mixer or mixing nozzle or mixing chamber an apparatus for
superheating air, or air and steam and one or more nozzles or orifices for projecting
the above named products, regulating cocks, valves &c.
The apparatus or generator consists of a combustion chamber of wrought or cast
iron or other suitable material, lined with fire brick or other suitable material similar
to that described in my Specification No. 3697 A.D. 1886, a chamber surrounding
the combustion chamber in which carbon or hydrocarbon is vapourized. From this
surrounding chamber the vapourized carbon or hydrocarbon is conveyed in a main or
pipe or pipes to a mixing chamber or mixer or mixing nozzle or nozzles, where it is
mixed or incorporated with air or air and steam and projected onto an incandescent
filter or grate under pressure. In this apparatus or generator the action is commenced
and maintained by producing incandescense on or of the grate and filter. The resultant
gases due to combustion are conveyed under pressure to an engine for use as a motive
power. The air may be heated by the exhaust gases from the engine or by radient
heat. The steam may be generated and superheated in a coil, any waste heat may be
used in heating liquid hydrocarbons.

page_text: I FRANCIS WINDHAM of 124 Cheyne Walk London in the County of Middlesex,
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 :-
It relates to Generators in which an incandescent grate or filter together with a
combustion chamber are employed similar to that described in my complete specification
of Patent No. 3697-1886; and differs entirely from those in which explosion or
combustion is produced by a naked flame, electric spark, or incandescent surface heated
by any supplementary means.
The object of the invention is to introduce certain improvements in the apparatus
or generator in which carbon, carbon compounds, or hydro-carbons with or without
the addition of water are vapourised, by the heat of their own combustion under
pressure and mixed with air.
The improvements consist-first, in the introduction of a vapourising chamber, and
in the employment of mixing nozzles, together with a recess or inlet passage in which
vapourised carbons or hydro-carbons are mixed or incorporated with air or air and
steam, and in which the firing takes place. Second, in the use of the external or sur-
rounding chamber as a regenerator or air heater, and also as a nonconductor of the
heat of combustion. Third, in the employment of an injector for the introduction of
the fuel air steam and water, as and in the proportions required. Fourth, in the intro-
duction of a second water supply beyond the incandescent grate. And fifth in the
combination of the incandescent grate with the arrangement described.
Referring now to the accompanying drawing in which similar letters refer to similar
parts throughout. Figure 1 is an outside elevation of the producer, figure 2 is a
sectional elevation and figure 3 is a sectional plan on the line A A. Figure 4 shows a
horizontal arrangement of the producer with the injector attached, figure 5 is a section
of the same and figure 6 an end view-Figure 7 is a plan of the feeding door.
The combustion chamber is represented by the letter B, the walls C of which are
composed of fire brick or other suitable refractory material, the grate or filter D which
is of similar material is situated near its lower end. Surrounding the combustion
chamber B an annular vapourising chamber E is formed its exterior wall F being of
iron plate or other suitable material: and outside the chamber E a second annular
chamber G is formed, which acts as a regenerator or heating chamber for the air used
for combustion which is admitted at H and also as a nonconductor of the heat generated
in the chamber B. The outside shell I of the producer which forms the outside wall
of the chamber G may be of iron or other suitable material. Below the filter D the
chamber B is provided with a suitable cleaning door J and a delivery pipe K. In
figures 4. 5 and 6 a cleaning door J¹ is provided. In figures 1 and 2 à petroleum
main L is shown together with small connecting pipes by which the petroleum or
other liquid fuel is conducted to the vapourising chamber E, the main L may be
supplied by a pump or other convenient means. The air admission pipe H conducts

page_text: the air which is supplied under pressure from a pump attached to the engine or other-
wise into the chamber G and from thence by the holes m in the nozzles M to the
recess N or inlet passage to the chamber B. In figures 3. 4. 5 and 6 a small cock O
is shown for the admission of water below the filter, and in figure 2. 0¹ represents
the end of the pipe connected with the cock O. The doors J J and Jare of ordinary
air tight construction, arranged to screw down upon a ring of asbestos or other
suitable material. The wall of chamber E is arranged to fit into groves in the
cover P and circular bracket Q, in which asbestos rings are placed, thus when the
producer is screwed up and ready for work, an air tight joint is formed. In figures 4.
5 and 6 an injector R is shown, air is forced in at s and rushing through the central
tube carries with it and mixes with the petroleum coal dust and water or other liquid
fuel which is forced in at t and the water which is forced in at u, the supply is regulated
by the hand wheel T.
The action of the producer is as follows. First in order to start it, a fire is lighted.
in the chamber B and the doors are closed, then a supply of air is delivered at H and
passing through M reaches the recesses N, the fuel supply is also delivered through L
and to the chamber E where it is vapourised upon C, the vapour passing into N
where it mixes with the air and immediately fires. The fire brick walls C of the
chamber B as well as the filter D rapidly become incandescent, and the fire upon D
burns out. The gases resulting from the combustion in chamber B after passing
through D are delivered at K for use in an engine, under pressure. A supply of
water may be delivered into the gases as they pass from the generator, at O. After
the producer is once started and the temporary fire has burnt out, combustion is
maintained by the incandescence of the wall C and filter D of the chamber B.
In figures 4. 5 and 6 an injector is shown which carries in the supply of fuel and
water by means of an air jet, heated air also enters from the nozzles M and firing
takes place at or near the recesses N.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is:
1. In Gas Generators using liquid fuel the use of an evaporating chamber E in
combination with mixing nozzles M and recesses N substantially as and for the
purposes described.
2. In Gas Generators using liquid fuel the use of an external annular chamber G
as an air heater and a nonconductor substantially as set forth.
3. The combination of an evaporating chamber, mixing nozzles, and passages with
an air heating, nonconducting chamber, in Gas Generators substantially as described
and shown.
4. The use of an injector for the supply of liquid fuel substantially as and for the
purposes described.
5. The introduction of a jet of water into the chamber containing the generated
gases as they pass from the producer as set forth.
6. The combination of an incandescent grate and walls of the combustion chamber B
with the evaporating chamber, mixing nozzles and passages, and air heating and
nonconducting chamber, and second water supply, by or in which combustion is pro-
duced assisted and maintained under pressure, and a steady supply of noncombustible
gas (dilute carbonic acid and steam) is driven off at a uniform pressure substantially
as shown.
