PROVISIONAL SPECIFICATION.
Improved Motive Power Engine.
I LOUIS ADRIEN BOISSET of 66 Rue de la Rochefoucauld, Paris in the
Republic of France, Engineer do hereby declare the nature of this invention to
be as follows:-
This invention consists in an arrangement of apparatus for producing motive
power by means of a gas generated in the apparatus itself, and in which the gas,
after use, is conveyed to a condenser, the liquid formed being used again and again
to generate the gas in the apparatus.
In carrying out this invention, I take advantage of the property of ammonia to
give off large quantities of gas in the presence of slight heat.
The apparatus consists of a generator, an engine, and a liquifier.
The generator is a vessel divided into two parts by a horizontal partition. The
gas is generated in the lower part, in which the liquid ammonia is placed, and
subjected to slight heat from a gas jet or an oil lamp, and it is then passed
through a suitable pressure valve into the upper part, where it is dried, previous
to use.
The gas next passes through a suitable pressure valve to the valve chamber of
the chamber of the engine piston cylinder,nd enters this chamber between two
slide valves, which are conveniently operata from the driving shaft of the engine.
The inlet and exhaust to and from both sides of the piston take place at both ends
of this chamber, as the case may be.
From the piston cylinder the used gas passes to a vessel which I term the
condenser, and in which it comes into contact with water, and becomes again
liquefied.
The liquid ammonia then flows to the well of a pump, by which it is raised to the
lower compartment of the generator.
In this compartment, the gas is again set free by the slight heat, and the
operations proceed as before.
I find that in general sufficient heat may be obtained for the purpose of
generating and drying the gas, from the products of combustion arising from
a gas jet or a lamp burner passing through a flue or chimney forming part of the
generator.
Dated this 22nd day of July 1892.

COMPLETE SPECIFICATION.
Improved Motive Power Engine.
I Louis ADRIEN BOISSET of 66 Rue de la Rochefoucauld, Paris, in the
Republic of France, 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 consists in an arrangement of apparatus for producing motive
power by means of a gas generated in the apparatus itself, and in which the gas,
after use, is condensed, the liquid formed being used again and again to generate
the gas in the apparatus, the amount of heat required to effect the purpose being
represented by one or two gas jets or oil lamps.
The complete suppression of the feed water, and the reduction to about one
[Price 8d

page_text: tenth of the fuel employed in machines of corresponding power at present in use,
renders this apparatus capable of application everywhere, more particularly where
space is an object, or where the reduction of weight to the minimum is a
consideration.
In carrying out this invention, I take advantage of the property of ammonia to
give off large quantities of gas in the presence of slight heat.
The apparatus consists of a generator, a condenser, and an engine properly
so called, all of which are connected together, and with one another, by a system
of pipes suitably arranged for the purpose.
And in order that my invention may be properly understood, I will now
proceed to describe it fully, reference being had to the accompanying drawing,
in which
Fig. 1 is a sectional elevation of the generator;
Fig. 2 shows the condenser in sectional elevation; and
Fig. 3 shows the engine properly so called, partly in section.
The generator consists of a cylindrical or other vessel divided into three com-
partments A A' A' by horizontal partitions.
The bottom compartment A is provided with a grate B. The middle com-
partment A contains a series of vertical tubes a a, which are open at bottom to
the part A, and at top to the bell mouth of a pipe C contained in the upper
compartment A2, from which it issues in the form of a chimney.
The compartment A' is provided with a water gauge glass b and a funnel e, and
it is connected with a pump D by the pipe, and with the distributing valve d by a
pipe g..
The compartment A2 is provided with a thermometer h, a safety valve i, a
manometer, a cock p, and a distributing valve d'.
a
In each of the compartments A' and A2 is a horizontal porous partition k k¹.
The condenser consists of a vessel E, provided with a water gauge b',
thermometer A, and a bung or plug . It is connected with the pump D by a
pipe f, and to the engine by a pipe m, in the length of which is arranged a valve n.
This pipe m projects nearly to the bottom of the vessel E.
The engine consists of a vertical cylinder F, in which works a piston o, which is
connected by a connecting rod with the crank shaft G. This shaft is supported in
suitable bearings, and carries a fly wheel and a transmitting pulley, the latter
driving, by means of a band, the rotary pump D.
On the side of the cylinder F, is a valve box H, the parts of which are, as in the
ordinary engines, worked by an excentric mounted on the crank shaft.
2°
The valve box is connected by a pipe with the distributing valve d on the
generator, and by the pipe m with the condenser.
At the top of the cylinder is a grease cup s, and at the bottom is a blow-off
valve t.
I will now describe the operation of the apparatus.
The solution or liquefied gas is poured into the compartment A' by the funnel e,
where it is heated by the ignited fuel on the grate B, and becomes vapourised.
The products of combustion pass away by the tubes a and escape by the chimney C,
rendering up their heat as they go.
By these means, the temperature in the compartments A¹ and A³ is raised to
about 50° C.
At about 25° C., the gas commences to disengage from the solution, and passes
through the porous partition k, where purification commences.
When the thermometer indicates 30° C., the valve d is opened, which permits of
the gas passing to the compartiment A, where it expands, and becomes purified and
dried by passing through the second porous partition k. At this moment, the
temperature is further raised to about 80° C., and the valve d' is opened, so that
the gas can pass by the pipe to the valve box of the engine or motor, the slide
valve of which admits the gas alternately to each end of the cylinder F, as in
ordinary engines.
"

page_text: The gas, when it bas produced the desired result, escapes through the box in the
usual way to the pipe m, whence it passes to the condenser through the valve n.
As the condenser contains some of the liquefied solution which has been introduced
through the opening 1, and which is maintained at a low temperature by any
suitable means, the gas on entering becomes rapidly condensed.
This cold solution is then withdrawn by the pump D, and is forced into the
generator A', to be vaporized again, and the action proceeds as before.
As will be seen, the solution performs a complete cycle, changing several times
its state.
There is therefore little or no loss, and the same quantity of solution will serve
for a long time.
It will be understood that the cock of the funnel e is closed when the com-
partment A' has received the requisite quantity of the solution, as indicated by the
gauge b, and the heating does not commence until the compartment is properly
charged.
It will be observed, also, that the "purger" t, placed at the lower part of the
cylinder F, consists of a cone kept to its seat by a spring, the tension of which is
greater than the interior pressure of the cylinder.
Thus, the cone can be raised only when an accumulation of condensed gas has
taken place in the cylinder, the liquid being conveyed by a suitable pipe to the
condenser.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
The general arrangement of apparatus substantially as herein shown and
described, and for the purpose set forth.
