Improvements in Carburetting Apparatus or Vaporizers for Internal
Combustion Engines.
I, ROBERT EDWARD PHILLIPS, of 30, George Street, Hanover Square, London,
in the County of Middlesex, Engineer, do hereby declare the nature of this
invention to be as follows:-
-
This invention relates to carburetting apparatus or vaporizers for internal
combustion engines, and it consists of the device hereinafter more particularly
described for agitating the oil so as to enable it to more readily vapourize.
According to this invention, a fan or its equivalent is mounted in a suitable
vessel which under some circumstances may be the oil reservoir and is adapted
to be set in motion either by the passages of the exhaust gases or products of
combustion as they escape from the cylinder or by the passage of the vapour into
the cylinder, or by both in combination.
The fan or its equivalent forming the agitator is preferably vertically arranged
and if used in combination with the oil reservoir is of such a length that it
will act upon the oil at all times irrespective of the quantity in the said reservoir.
As an alternative construction the fan or its equivalent may be a shallow one
adapted to act either on the oil or at a small depth therein, the said fan being
automatically kept at the desired point of immersion by means of a float, in
which case it would be mounted on the shaft which drives it so that it can rise
and fall thereon.
Motion is imparted to the fan or agitator by means of a fan wheel or its
equivalent adapted to be operated either by the passage of the exhaust gases from
the cylinder or by the passage of the vapor from the carburetting apparatus to
the mixer or by the passage of the vapor from the mixer to the cylinder. In
the former and latter case it is obvious that the fan driving wheel or its equivalent
would be arranged exterior to, or in a separate compartment from, the car-
buretting chamber.

Improvements in Carburetting Apparatus or Vaporizers for Internal
Combustion Engines.
I, ROBERT EDWARD PHILLIPS, of 30, George Street, Hanover Square, London,
in the County of Middlesex, 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 relates to carburettors for internal combustion engines using

page_text: light oil, and it consists of a paddle wheel or its equivalent adapted and arranged
to agitate the oil, the said paddle wheel or its equivalent being set in motion by
the escape of the exhaust gases or products of combustion from the cylinder of
the engine acting on an air-turbine or its equivalent.
In the accompanying drawing, which-by way of illustration-shows this
invention applied to a surface carburettor :-
Figure 1 is a view in side elevation partly in section and Figure 2 is a view in
plan.
Throughout the views similar parts are marked with like letters of reference.
The paddle wheel A or its equivalent forming the agitator is preferably
arranged vertically and if used in combination with a surface carburettor such
as X it is either made of such a depth that it is always more or less immersed
in the oil, or it is of shallow construction and made either wholly or partially of
such material or materials that it will float on or near the surface of the oil so
that only a part of its depth is submerged.
In the latter construction which is the one illustrated the paddle wheel A has
a block a of cork or other light material on its boss and it is adapted to slide on
the axle B and yet rotate therewith so that it is free to rise and fall thereon
following the level of the oil, its depth being regulated by the floating capacity
of the block a.
In a suitable position preferably exterior to the tank X is an air-turbine C
the axle of which is either formed in one with or coupled to the upper end of
the axle B on which the paddle wheel A is mounted either by means of a screw
or feather engaging a key or featherway or an equivalent device. The case D
of the air-turbine is provided with two openings the one & connected to the
exhaust pipe E from the cylinder and the other connected to a pipe F leading
to the silencer if one is used, the arrangement being such that the exhaust gases
or products of combustion from the cylinder act on the air turbine C during their
escape and thus impart motion to the paddle wheel or agitator_A.
The case D of the air-turbine is enclosed by a suitably shaped cover G which
is provided with a suitable number of holes g so arranged that the air which
passes into the carburetting tank X through the holes a, e, therein has to pass
over and around the case of the air-turbine and thus becomes heated whereby it
is enabled more readily to absorb the vapour of the oil.
I prefer to place at a convenient position above the highest level of the oil
in the tank X à screen Y of gauze or other suitable material to prevent the spray
formed by the agitator being sucked up into the mixing valve Z which may be of
the well-known type illustrated or of any other suitable type.
It will be obvious that this invention may be applied to all types of surface
carburettors and is not restricted only to those surface carburettors combined
with oil tanks as shown in the accompanying drawing.
I wish it also to be understood that I do not limit myself to the construction
and arrangement of parts hereinbefore described and illustrated by the accom-
panying drawing, but 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;-
The combination and use with a surface carburettor for internal combustion
engines, of an agitator set in motion by the exhaust gases or products of com-
bustion in their escape from the cylinder of the engine.
