Improvements in or relating to Internal Combustion Motors or
Engines.
A communication from CHARLES DE HAUPT, of 2, Rue de la Sablonniere, Brussels,
in the Kingdom of Belgium, Stockbroker.
I, ALFRED JULIUS BOULT, of 111, Hatton Garden, in the County of Middlesex,
Chartered Patent Agent, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:
This invention relates to internal combustion motors or engines and particularly
to means for supplying air saturated or charged with oil to the motor or explosion
chamber, and means for heating and vapourising said charge on its way to the
explosion chamber; and, at the same time, heating the ignition tube or device;
the invention further relating to the means for mixing the vapour with air and
admitting the charge to the explosion chamber.
In the accompanying drawings an apparatus according to this invention is
illustrated comprising a mixing device, a vapouriser, an ignition and heating
device, a lanp or burner in connection therewith, and a valve apparatus.
Fig. 1 is a vertical section on line a-x, Fig. 2:
Fig. 2 is a longitudinal view partly in section of the general apparatus:
Fig. 3 shows a section through the vapouriser:
Fig. 4 shows the lamp casing:
Fig. 5 is a top view of the petroleum feeding and heating device for the lamp,
and
Fig. 6 is a plan view of the mixing device or reservoir.
The oil, say petroleum, is introduced into the reservoir A, through a suitable
opening, until the level reaches say to two-thirds of the height of the reservoir,
the rest of the chamber above the level of petroleum, being filled with compressed
air, by means of a pump, say a cycle pump or the like attached to a valve B and
worked by hand or by a pump operated by the motor itself.
The petroleum forced out of this reservoir enters two conduits C and D which
are closed respectively by the two taps E and F.
The ends of the pipes C and D extend into the reservoir A and end in fine
meshed metallic straining tubes or covers a, b with a view of preventing the
passage of any impurities.
The tube C conducts the petroleum to the vapouriser G it passing through a
very small hole d-say 12 mm.-in the tube connection c and thence into the
serpentine or coiled pipe H of the vapouriser after which it enters the mixing
chamber through a small hole e of say mm. diameter.
The tube D leads the other supply of oil to the lamp or burner K which con-
sists of a bent tube which is preferably divided at its upper part into two
passages f (Fig. 5).
The tube descends on the opposite side until it reaches the central part beneath

page_text: the quadrangle formed by the branches where it is turned upwards and provided
with a hole or burner i for the exit and burning of the heated oil.
The lamp is covered with a casing L, Figs. 3 and 4, which is provided with
crifices so as to admit to the flame the necessary supply of air.
The working of the apparatus is as follows:
After the reservoir has been filled with the requisite quantity of oil, air is
pumped into it through the valve B until the desired pressure is obtained.
The amount of pressure can be indicated by a pressure pump, screwed into the
cover g of the reservoir.
The required pressure having been obtained, alcohol is poured into the reservoir
or base of the lamp K and ignited, after which the regulator tap F is opened.
The oil will now pass along the conduit D into the tubes f, f, of the lamp unti!
it reaches the orifice where the oil already heated by the alcohol flame will
ignite and henceforward continuously heat the tubes f¹ forming the quadrangle,
whereby the oil for the lamp becomes vapourised and, owing to the casing L
forming a kind of Bunsen burner, when ignited has a great heating power.
The same flame also heats, up to white heat, the igniter M connected to the
explosion chamber and coiled tube H. At this stage the regulator tap E is opened
and the petroleum necessary for the working of the motor actuated by the com-
pressed air, passes through the conduit C and the small passage into the coiled
tube H where it becomes vapourised, the vapours passing through the orifice e
into the mixing chamber I and thence through a valve N into the explosion
chamber of the motor where the igniter M effect the explosion.
The construction of the valve box and mixing device and the action of the
inlet and exhaust valves N and P will now be described.
The inlet valve (Figs. 1 and 2) consists of the valve body N provided with a
central tube which is open at its lower end, and in addition is provided with
holes m and serves for the purpose of introducing by suction, air through the
orifices n in the upper part of the tube.
The result of such an arrangement is, that when the valve N is lifted the charge
from the vapouriser enters the explosion chamber together with pure air ad-
mitted through the orifices m and thus forming a very effective explosive
mixture. The spring R presses against the valve to keep it normally on its seat.
The valve P provided with spring S is actuated from the motor and serves for
the removal of the gases of combustion.
Any convenient means may be employed for actuating the valves at the required
times.
Having now particularly described and ascertained the nature of the said inven-
tion as communicated to me by my foreign correspondent and in what manner the
same is to be performed, I declare that what I claim is:
1. In an internal combustion motor or engine a closed liquid fuel reservoir
means for introducing compressed air into said reservoir and a tubular conduit
between the reservoir and the explosion chamber of the motor substantially as
described.
2. In an internal combustion motor or engine a closed liquid fuel reservoir
means for introducing compressed air into said reservoir and a tubular conduit
between said reservoir and explosion chamber of the motor and a second tube
issuing from said reservoir for supplying liquid fuel to a burner for heating the
liquid in its passage through the first tubular conduit and also if desired for
heating an ignition tube of the motor substantially as described.
3. Means for heating the liquid fuel in its passage through the tube between the
reservoir and the explosion chamber comprising an oil supply and vapourising
tube f f so formed that its flame shall not only heat the liquid fuel in the tube
leading to the combustion chamber but also heat its liquid fuel on its way to tho
burner substantially as described.
4. A tubular conduit between the liquid fuel reservoir and the explosion chamber

page_text: of an internal combustion motor or engine comprising a tube C provided with a
nozzle d, a coiled tubular extension H and exit nozzle e substantially as described.
5. A heating device of the character described comprising a coiled tube H
provided with an enclosing casing and a burner K substantially as described.
6. Carburetting apparatus for internal combustion motors or engines comprising
a chamber provided with a vapour inlet a tubular valve N means for admitting air
to the mixing chamber an explosion chamber and means for igniting the explosive
mixture substantially as described.
7. The complete mixing chamber and valve substantially as described and illus-
trated in Figures 1 and 2 of the accompanying drawings.
S. The complete carburetting apparatus for internal combustion motors or engines
substantially as described or illustrated in the accompanying drawings.
