COMPLETE SPECIFICATION.
A Motor Engine Worked by Ether Vapour or other Volatile Fluid
in Combination with a Steam Engine.
I, PAUL DE SUSINI, of 6, Rue de Sfax, Paris, France, Doctor of Medicine, 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:-
My invention relates to a construction of ether vapour motor engine to be.
worked in combination with a steam engine, in such manner that, firstly the waste
heat of the gases from the steam boiler furnace, and secondly the waste heat of the
exhaust steam from the steam engine shall be effectually utilised in working the
other vapour engine.
For this purpose, firstly the combustion gases of the steam boiler furnace are
caused, before escaping up the chimney to impart the greater part of their heat to
an auxiliary steam boiler, the steam from which is made to pass first into a steam
jacket surrounding the high pressure cylinder and slide valve chest of a compound
ether vapour engine so as to prevent condensation of ether vapour in such cylinder
and slide valve chest, and then it passes into a steam jacket and heating tubes of a
generator of ether vapour, so that such vapour is produced by the heat of the steam
and passes from the generator to the steam jacketed high pressure cylinder of the
engine, secondly the exhaust steam from the steam engine is caused to pass into a
steam jacket surrounding the large cylinder and slide valve chest of the ether vapour
engine, so as to heat these parts and prevent the ether vapour from condensing
therein, from such steam jacket the exhaust steam is then led into a second ether
vapour generator, the ether vapour from which is made to work in the low pressure
cylinder of the ether vapour engine together with the vapour coming from the high
pressure cylinder.
Figure 1 of the accompanying drawings shows a motor engine worked by ether
vapour or the vapour of other volatile liquids generated by the waste heat of an
ordinary steam engine and boiler according to my invention;
Fig. 2 shews a sectional plan on line a-b Fig. 1.
Fig. 3 shews a vertical section of the generator of ether vapour.
V is a steam boiler heated by the hot combustion gases from the furnace of an
ordinary steam boiler that works a steam engine. The steam from this boiler is
led through a pipe V₁ with shut off valve V to the jacket A enclosing the small
cylinder B and slide valve chest of the compound ether vapour engine.
After circulating through this jacket the steam passes through a pipe I)
surrounding the supply pipe E for ether vapour to the small cylinder B which
pipe D opens into the upper chamber F of the ether vapour generator G from
which it passes down through the tubes a a into the lower chamber H while at the
same time it passes down through the jacket I surrounding the generator. The
chamber between F and H containing the pipes a is charged with the ether or
other volatile liquid, which in coming in contact with the outer surfaces of the
tubes a becomes vaporised by the heat of the steam, the resulting ether vapour being
led off to the slide valve chest and small cylinder of the engine through the pipe E
which is enclosed by the pipe D.
The vapour being expanded to a certain extent in the cylinder B then passes through
exhaust passage J into the chamber K whence it passes to the slide of the large
cylinder G. At the same time, the exhaust steam from the aforesaid steam engine
after passing from the pipe V³ through the jacket of the cylinder C passes thence
through the pipe X into the upper chamber of a second vapour generator U of the
same construction as the generator G and the resulting ether vapour is led through
a pipe, within the pipe X to the chamber K where it mixes with the vapour

The exhaust vapour from this cylinder then passes through pipe L to the surface
condenser N of any suitable known construction, working either with water or
moist air.
The liquid ether produced in the condenser is withdrawn through a pipe N by a
pump N which forces it into the generators G and U again through pipes N' N³ in
order to be re-evaporated.
The stuffing boxes o p q r of the piston and slide valve rods are supplied
with glycerine or other lubricant that will not combine with ether, from
reservoirs O. P. Q. R for lubricating the rods and stopping any leakages of ether
vapour that may accidentally take place.
The said reservoirs O. P. Q. R are connected by pipes s t u v having
cocks s¹¹¹¹, with a main reservoir S by which they are supplied and in which
are collected any particles of ether vapour that may escape up such pipes and
which are conducted through a pipe at top to the condenser. The reservoir S is
provided with a pressure gauge T that can be made to communicate with either
of the reservoirs O. P. Q. R by opening or closing the cocks &¹ t¹ u¹ v² on the
pipes as described in my application bearing equal date herewith.
Having now particularly described and explained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The combination with a steam engine of a motor engine worked by ether
vapour or other volatile fluid in such manner that the exhaust steam from the
steam engine is made to pass into a jacket of the ether vapour engine so as to heat
the same and prevent the condensation of the ether vapour therein, substantially as
described.
2. The combination with a steam engine of a motor engine worked by ether
vapour or other volatile fluid in such manner that the exhaust steam from the
steam engine is made to pass into the jacket and heating tubes of an ether vapour
generator, so as to produce ether vapour by the heat of the exhaust steam while at
the same time the latter is condensed, such supply of exhaust steam being regulated
by a cock or valve so that the ether vapour engine can be started and stopped
whenever required, substantially as described.
3. The combination of a motor engine worked by ether vapour or other volatile
fluid with an auxiliary steam boiler heated by the hot combustion gases from the
furnace of a steam boiler that works a steam engine, the steam thus produced being
used for heating the cylinder of the ether vapour engine substantially as described.
4. The combination of a motor engine worked by ether vapour or other volatile
fluid with an auxiliary steam boiler heated by the hot combustion gases from the
furnace of a steam boiler working a steam engine, the steam from such auxiliary
boiler being used to heat a generator of ether vapour for working the said motor
engine, so that by opening or closing a valve on the steam supply pipe the ether
vapour generator and engine can at once be thrown in or out of action substantially
as described.
5. The combination with a steam engine of a compound ether vapour motor
engine, two ether vapour generators an auxiliary steam boiler heated by the hot
combustion gases from the furnace of a steam boiler that works the steam engine,
and a surface condenser of ether vapour, the high pressure cylinder of the ether
vapour engine and the one ether vapour generator being heated by the steam from
the said auxiliary steam boiler while the low pressure cylinder and the second
ether vapour generator are heated by the exhaust steam from the said steam engine,
substantially as described.
