Complete Specification Accepted, 5th Feb., 1889
I ALFRED WILSON of Stafford in the County of Stafford, Engineer, do hereby
declare the nature of this invention to be as follows:-
This invention has reference to those arrangements of gas engine in which the
gas engine is combined with a gas producer.
In such arrangement it has heretofore been usual to provide means for generating
stean under pressure for use in inducing or propelling currents of air or air and
steam through the gas producer.
Objects of this invention are to dispense with the necessity of providing special
means for such generation of steam under pressure, and to more perfectly utilize the
heat generated in the production of motive power in such arrangements of gas
engine and gas producer. According to this invention for the purpose of obtaining
increased simplicity and economy in such combinations of gas engines and gas
producers employ a jet of air or a jet of the products of combustion passing out
of the cylinder of the gas engine and known as the Exhaust-to inject or suck a
current of air or air and steam or water, or water vapour to form mixtures suitable
for gasifying fuel in the gas generator.
The air or the products of combustion for forming the initial jet may be obtained
from a receiver or reservoir that is supplied either direct by and with a portion of
the exhaust gases of the engine or by means of a pump worked by the engine itself
or by other convenient means.
lustead of using a jet of air or a jet of the products of combustion from the gas
engine to force the current into the gas producer for burning the fuel therein I may
in some cases employ a pump to force the whole of the air required mixed with a
certain proportion of the exhaust gases, or products of combustion from the engine,
or with water or water vapour.

page_text: Mixtures of air and gases or vapours such as described whether propelled by a
jet arrangement or exclusively by a pump may in some cases be passed through
a regenerator of the kind described in the specification of Letters Patent granted to
me No. 1699 A.D. 1882. Water may be put into the regenerator along with the
mixture to be heated so as to produce water vapour or steam in case there is no other 5
supply of steam available.

L, ALFRED WILSON, of Stafford, in the County of Stafford, Engineer, do hereby
declare the nature of this invention, and in what manner the same is to he
performed, to be particularly described and ascortained in and by the following
statement:
This invention has reference to those arrangements of gas engines in which the
gas engine is combined with a gas producer. In such arrangements it has heretofore
been usual to provide means for generating steam under pressure for use in inducing
or propelling currents of air or air and steam through the gas producer.
Objects of this invention are to dispense with the necessity of providing special
means for such generation of steam under pressure and to more perfectly utilize the
heat generated in the production of motive power in such arrangements of gas engine
and gas producer. According to this invention for the purpose of obtaining increased
simplicity and economy in such combination of gas engines and gas producers I
employ a jet of air or a jet of the products of combustion passing out of the cylinder
of the gas engine, and known as the exhaust, to inject or suck a current of air or air
and steam or water, or water vapour to form mixtures suitable for gasifying fuel in
the gas generator. The air or the products of combustion for forming the initial jet.
may be obtained from a receiver or reservoir that is supplied either direct by and with
a portion of the exhaust gases of the engine or by means of a pump worked by the
engine itself or by other convenient micans. Instead of using a jet of air or a jet of
the products of combustion from the engine to force the said air or other current into
the gas producer for burning the fuel therein 1 may in some cases employ a pump to
force the whole of the air required mixed with a certain proportion of the exhaust
gases or products of combustion from the engine or with water or water vapour.
Mixture of air and gases or vapour such as described whether propelled by a jet
arrangement or exclusively by a pump may in some cases be passed through a
regenerator of the kind described in the specification of Letters Patent granted to me
No. 1699, A.D. 1882.
Water may be put into the regenerator along with the mixture to be heated so as to
produce water vapour or steam in case there is no other supply of steam available.
On the accompanying sheet of drawings there is shewn a gas engine provided with
arrangements for inducing or propelling currents of air and waste gases and steam
through a gas producer.
A is the cylinder of the engine; B a pipe leading from the cylinder and serving as
an outlet for gases: (a back pressure valve and stop valve: D a receiver for gases
or for mixtures of exhaust gases and air from the pump or for air alone; E a pump to
pump air or exhaust gases or both into the receiver or direct to the gas producer or
generator. Jis the air inlet to the pump; K is a pipe leading from the air inlet J

page_text: to the exhaust pipe L. Fa jet or injector or ejector operated by compressed air or
gas or both to force or sck air through the gas producer or generator: H water or
Steam supply to form a mixture of water or steam with th air forced by the jet F.
It will be understood that the whole of the arrangements shewn on the drawings
are not necessarily employed in every case. For instance the pipe B, valve C,
pipe O, receiver D and jet F may be employed apart from the pump E, air inlet J,
and pipe K and with or without the water supply II. Under such conditions a
portion of the inflamed charge will pass the valve (at ench explosion in the cylinder A
and will enter the receiver D, the amount of gases depending upon the degree of
lift allowed to the valve and to the pressure in the receiver. This receiver acts as an
equalising vessel to maintain an approximately constant jet at F during the non
impulse strokes of the piston. The gases are emitted at F and induce a current of air
in the cone opposite in a way which is well understood.
If steam is supplied at II it is carried forward with the air or if water be omitted it
is more or less broken into spray or atomised by the same means.
When the engine
is furnished with a pump air may be forced by this pump direct through the pipe M
and the valve N to the producer. Or the air drawn into the pump may be heated by
admixture with exhaust gases passing from the exhaust through the pipe K to the
inlet J, the proportion of air and gases being regulated by the cock or valves on the
respective pipes. Or the discharge from the pump may be delivered through the
pipe O into the receiver D and be employed to feed the jet F.
Under these lattor conditions there would be required a smaller quantity of air at a
higher pressure than when working direct from the pump to the gas generator.
Having now particularly described and ascertained the nature of said invention
and in what manner the same is to be performed I declare that what is claimed in
combined arrangements of gas engines and gas producers is
1. The use of gases delivered under pressure from the engine cylinder to indner a
current of air through the producer substantially as describe.
2. Heating tho air delivered to the producer by admixture with exhaust or hot
gases from the engine cylinder substantially as described.
3. The combination with an engine of a pump delivering air with admixture of
exhaust or hot gases to the producer either directly or through a jet blower
substantially as described,
4. The combination with a gas engine of a pipe B leading from the cylinder, a back
pressure valve, a receiver D and a jet Substantially as described and for the
purpose specified."
5. The combination with a gas engine of a pump E with air inlet J and pipe K
connected to the exhaust with or without the receiver D and jet F substantially as
described.
6. The combination with a jet blower or air injector operated by gases from the
cylinder of a gas engine, or air mixed with such gases, of a water or steam supply
substantially as described and for the purpose specified.
