I, FELIX ROLAND, of N° 63 rue Roussin, Paris, in the republic of France, Civil
Engineer do hereby declare the nature of the said invention for "AN IMPROVED
MOTOR WITHOUT BOILER AND DRIVEN BY MEANS OF SULPHURET OF CARBON
to.
be as follows:-
"
This invention consists of a motor without boiler and driven by means of
sulphuret of carbon.
In carrying out the invention I provide a cylinder and a piston which communi-
cates motion to the main shaft by means of a connecting rod. At one side of the
cylinder I provide a vessel into which a pump, the speed of which is increased or.
diminished by a regulator or governor injects liquid sulphuret of carbon, previously.
heated (or not) by being caused to pass into a receiver utilizing the waste heat
from the chimney. The said vessel communicates with the slide box by means of
one or several tubes passing beneath the cylinder-These tubes, together with the
vessel, the cylinder and the slide-box are contained within a reverberatory furnace
of metal, brick or other suitable material, heated by any suitable known means-
The liquid injected by the pump into the vessel passes from there into the slide-
box and thence into the cylinder and its vapour acts on the piston, which is
constructed of alternate disks of asbestos and metal or other suitable disks pressed'
together-When the vapour has been utilized it passes into a condenser cooled by
air or by other suitable means, which condenser may be provided with an air valve.
for the purpose of preventing, when necessary, the creation of too great a vacuum.
in this condenser. The condensed sulphuret of carbon is again taken up by the
pump so that the same liquid is continuously re-used-The rods of the piston,
slide valve and pump traverse a safety box constructed of two successive stuffing
boxes between which is a chamber communicating freely with the condenser to
prevent any escape of vapour.

I FELIX ROLAND, of N° 63 rue Roussin, Paris, in the republic of France, Civil
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 :-
The improved motor which is driven by sulphuret of carbon without boiler is a
condensing engine of variable expansion which may be regulated by hand or by
means of a governor.
In order to enable the invention to be fully understood I will proceed to describe
the same by reference to the accompanying drawings in which figure 1 is a vertical.
section of the improved motor; figure 2, is a longitudinal section of the same (the
connecting rods and the driving shaft which are of the ordinary construction not
being shewn) Figure 3, is a section of the feed pump. Figure 4, is a section of one
of the safety boxes or chambers. Figure 5, shews a new arrangement of safety
valve.
This machine is constructed,
1stly of a hollow cast or wrought iron frame.
2ndly of a cylinder B shewn in figures 1 and 2 placed in a reverberatory furnace-
It is provided with longitudinal ribs and is enclosed by another cylinder F, figures 1
and 2 the sides of which are corrugated, the whole being enclosed by a cylinder G.
which forms the jacket of the hot bath. This cylinder is double acting but I
sometimes make it single acting and can employ in this machine any suitable
number of cylinders-The cylinder can be made of any suitable material and can
be lined with platinum or an alloy, or enamel or other suitable material.
3rdly Of the piston C shewn in figures 1 and 2. This piston is double acting
and works in the cylinder B with slight friction forming a hermetic joint. It is
formed of a cylindrical piece fixed to the rod by a nut a. The piston is provided]
with a series of metal rings V, V, V, between which are interposed coils of
asbestos X, X, X, X, compressed by means of the nut b, which can be provided
with a stop arrangement for the purpose of preventing it becoming unscrewed-
By more or less operating the nut b, the asbestos packing which surrounds the
piston can be compressed as required and caused to be pressed out against the
inner surface of the cylinder according to whether a greater or less degree of
friction is required to be given to the piston in the cylinder whereby the necessity
for lubrication is dispensed with.
4thly Of the reheater shewn at A, figure 1, and in section at figure 2. It is
arranged around the chimney and on the arch of the reverberatory furnace and is
adapted to receive through the tube c, the sulphuret of carbon injected by the
pump for the reheater. It serves as a receiver for compressed air whence the
sulphuret is injected into the cylindrical receiver D, which serves as a slide box
(figures 1 and 2) through the pipe e, when the cock R, is opened. This compressed
air reheater which is of great utility for starting the motor is of a cylindrical

shape and is bellied out at its upper part and can be constructed of cast or wrought;
iron, steel; copper or other suitable metal. It is provided with a pressure gauge,
and a safety valve for discharging the surplus when too much sulphuret is injected,
by the pump.
5thly Of the slide box D figures 1 and 2. The slide box is cylindrical and is
formed with corrugations F and surrounds the cylinder B; it contains the vapour
of the sulphuret of carbon. This vapor is put in communication with the reheater A,
which contains the motive fluid, when the cock R is opened, by means of a pipe e,
(shewn broken off in the drawing) extending at a suitable point into the slide.
box D.
6thly Of the equilibrium piston cylindrical slide valve T (figure 1) which like
the motive piston C is constructed of a series of iron discs between which are:
interposed discs of asbestos, tightened upon the rod by nuts. By more or less
screwing these nuts the asbestos discs can be expanded as required so as to obtain
a perfect joint. The slide has a to and fro movement communicated to it by an.
eccentric which moves a connecting rod.
7thly Of a heating apparatus constructed (1) of a reverberatory furnace M, which-
comprises the dome r, and its chimney 8, the fire place t, and the ash pit u; (2) of
a tubular hot bath consisting of a cylindrical receiver G, which surrounds the:
slide box D, figures 1 and 2 and provided at its lower part with two collecting
tubes a and a¹ To the tube a, is jointed by a suitable connection a series of tubes
which pass down into the fire place t, so as to form the bars of the grate z ;
figure 2 shews a side view of these tubes and figure 1 a front view of the same.
The liquid from the heated bath freely circulates through these tubes and there is:
an ascending current from the tubes into the collector a and a descending current
from the collector a' through the tubes g, gl, which are outside the fire place up
to the collector al; the bath is filled through an upper tube and is emptied
through a cock placed on the collector a¹¹, The liquid of the bath may be linseed:
oil or water saturated with different known salts and even in certain cases with.
acetate of soda.
The apparatus may be heated (1) with any suitable fuel (2) by gas (3) with:
mineral or other oils (4) with water steam. It will be obvious that I can heat the.
parts contained in the fire place direct without the herein before described bath..
8thly Of an apparatus for condensing the vapour formed of a number of metallic.
winged or corrugated tubes projecting into a collector in which the liquid resulting
from the condensation is deposited and whence it is drawn by the pump for.
forcing it into the reheater A through the tube b, figure 1. The condenser is
cooled either. by a current of water or by a current of cold air.
9thly Of a feed suction and force pump shewn in section at figure 3, without
valve, provided with a valve cock and the piston x, of which consists of a series
of metal discs between which are interposed discs of asbestos; it is provided at m,
with a stuffing box and at n, with a chamber serving to collect any leakage
through the piston. This chamber communicates by a tube with the condenser.
The pump is thus rendered perfectly tight.
10thly Of safety boxes shewn at figure 4 which have for object to prevent the
escape of vapour outside the apparatus. The piston rod, slide valve rod and pump
rod are each provided with one of the said safety boxes; h, is the first stuffing box
and h¹, the second stuffing box; j, chamber from which passes a pipe o, which
communicates with the condenser into which is conducted any small quantity of
vapour which passes through the stuffing box h.
11thly Of a suitable governor of known construction such as a ball or anchor
governor which serves to regulate the admission of vapour into the cylinder by
varying the stroke of the slide valve T, figure 1. It also serves at the same time
to regulate the delivery of the pump by varying the stroke of its piston.
12thly Of metallic pressure gauges and the safety valve shewn in section at
figure 5. This spring valve is provided with a plug q, formed of iron discs and
asbestos discs which can bear with more or less pressure on the spring p, according

page_text: to the degree of tension at which the valve is required to work. The safety valve
communicates by means of the tube k, with the condenser into which it throws
the vapour when the valve is raised.
My improved motor is applicable for most purposes. It can be employed for
purposes of navigation, for railways and tramways, for omnibuses, carriages of all
kinds, velocipedes, etc and for aërial navigation by reason of its great power and
lightness. It can be constructed vertical or horizontal, fixed or-portable and can
be arranged as a road machine without fire or smoke and without any apparent
escape of vapour it is not liable to frighten horses and can be employed for
underground railways without inconvenience to the passengers.
The vapour of sulphuret of carbon can be applied as a motive power to
machinery, implements, steam hammers, perforating machines, as well as to
compressing air for compressed air engines etc.
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 a motor without boiler the employment of sulphuret of carbon as a motive
fluid or agent substantially as hereinbefore described.
2. Injecting and vaporizing the motive fluid in the slide valve box or in the
cylinder substantially as herein before described.
3. The production by the means herein described of the vapour of sulphuret of
carbon in the required quantity and instantaneously according to requirements

before described.
6. The employment of a piston and a slide valve packed with asbestos which
allows the machine to work easily without lubricating the cylinder substantially
as herein before described.
7.. The employment of a piston without piston valve and packed with asbestos
so as to render it completely tight substantially as herein before described.
8. The employment of a safety valve having a plug packed with asbestos for
rendering it tight substantially as hereinbefore described.

carbon and storing the pressure so as to facilitate the starting of the machine
without operating the fly wheel substantially as hereinbefore described.
10. The improved motor herein before described and represented in the accom-
panying drawings.
