I JOHN HENRY JOHNSON of 47 Lincolns Inn Fields in the County of Middlesex
Gentleman do hereby declare the nature of this Invention to be as follows:-
This Invention relating to apparatus for carburetting air consists essentially in so
constructing the said apparatus that a jet or stream of hydrocarbon liquid is caused to
meet and become mixed with a jet or stream of warm or heated water as hereinafter
described. By these means the whole of the hydrocarbon is enabled to be volatilized
or converted into vapour and the waste is reduced. Cooling of the liquid at the time
of its evaporation is also obviated and the gaseous mixture is maintained at a regular
temperature carburetters constructed according to this invention well adapted for
supplying gas engines drawing gas direct from the carburetter; the carburation
being absolutely constant or uniform and the irregularity of speed resulting from the
employment of ordinary carburetters is obviated.
In a carburetter constructed according to this Invention the hydrocarbon is
supported through a tap or cock the orifice of which is provided with a balanced valve
connected with the engine governor so as to regulate the flow of liquid according to
the consumption of vapour.
The liquid falls from this tap on to a brush where it meets a thin stream or jet of
heated water supplied from another tap. This brush divides and distributes the liquid
in a thin stream or film over the surface of a helical brush situated underneath the
first brush and serving to complete the mixing and facilitates the evaporation.

page_text: This helical brush is continued in a tube or cylinder surrounded by warm water
which may be supplied from the motor. The same water may also be mixed with the
hydrocarbon as hereinbefore described. The lower end of this tube or cylinder is
provided with a valve through which the remaining liquid and the carburetted air
escape into a chamber from which the carburetted air or vapour passes to the motor
through a tube provided with a valve in order to prevent accidental explosions. The
water is collected in the bottom of this chamber whence it is drawn off by a perforated
pipe. A float of cork or other buoyant material is placed on the surface of the water
in the chamber in order to prevent splashing or disturbance of the liquid arising from
the sudden exhausting action of the motor.

1, JOHN HENRY JOHNSON of 47 Lincolns Inn Fields in the County of Middlesex
Gentleman do hereby declare the nature of this Invention which has been communi-
cated to me from abroad by Edouard Delamare Deboutteville and Leon Paul Charles
Malandin both of Fontaine le Bourg Seine Inférieure in the Republic of France,
Manufacturers and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
The improvements forming the object of this Invention relate to apparatus for
carburetting air for supplying motive power engines or other purposes the air being
drawn into the apparatus by the action of the engine itself when employed in
connection with a motor. These improvements consist essentially in the simultaneous
introduction of a jet of hydrocarbon and a fine or thin stream of hot water the latter
accelerating the volatilisation of the hydrocarbon and reducing the waste to a minimum.
By these means the excessive cooling of the liquid at the time of its evaporation is
prevented and the gaseous mixture is maintained at a uniform temperature."
By these means the hydrocarbon is utilised to a maximum degree and the car-
buretted air or vapor engines are enabled to be worked much more economically than
with ordinary carburetters-The carburetting action being absolutely constant the
force produced is equally so and the irregularity of speed attending the employment
of the ordinary carburetters is entirely obviated-The hot water used in the improved
carburetters also has the effect of clearing the liquid from the solid matter in suspension
which would be liable to foul the engine. Vapor engines are thus enabled to work
with petroleum and its carburets without being liable to have the working parts made
foul with deposits as is the case when ordinary carburetting apparatus is employed.
And in order that my said Invention may be fully understood I shall now proceed
more particularly to describe the same and for that purpose shall refer to the several
figures on the annexed sheet of drawings the same letters of reference indicating
corresponding parts in all the figures.
Figure 1 of the sheet of drawings annexed represents a vertical section of a
carburetter constructed according to my Invention and composed of a vessel Z for the
carburet, furnished at its lower part with an adjustable tap or cock R for regulating
the discharge-The outlet orifice of this tap is provided with a balanced valve S as
indicated in figure 2 which represents the tap R drawn to a larger scale-This valve is
connected at a to the governor of the motor in such a manner that when the said
governor cuts off the supply of gas or vapour to the engine it also closes the valve S
and the supply of liquid to the carburetting apparatus is thus automatically regulated
according to the consumption of gas or vapour.
The liquid thus supplied falls on to a dividing or distributing surface such as a
brush b at the same time as hot water is supplied from a tap R-This brush 6 divides
and distributes the liquid in a thin stream or film over the entire surface of a helical
brush M which completes the mixing and facilitates the evaporation-―This helical

page_text: brush M is contained in a tube or cylindrical case provided with a hot water jacket T
which may be supplied with water from the motor at E and escape at E-This hot
water is indispensable for ensuring a regular action.
The remaining liquid and the carburetted air are discharged at D through a valve V
which serves to prevent the escape of vapour-The carburetted air or vapour is
supplied to the motor through a tube A surmounted by a valve B (shown drawn to a
larger scale in Figure 3) which removes all danger of explosion in the apparatus
arising from a rush of flame from the engine and the water is collected in the lower
vessel C whence it is drawn off through a perforated pipe (".
A cork or other float L is placed on the surface of the water in the vessel C. in order
to prevent splashing or disturbance of the liquid arising from the sudden exhausting
action of the motor-It is evident that the apparatus illustrated by way of example in
the drawing may be variously modified as regard details of arrangement and con-
struction without affecting the principle of the invention.
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
1st. In an apparatus for carburetting air effecting an intimate mixture of the
hydro carbon or carburet with hot water in order to facilitate and equalize the
production of carburetted air or vapour suitable for gas engines or motors or for
lighting or other purposes the said mixture being effected by directing a jet of
hydrocarbon liquid or carburet and a fine stream of water on to a brush or other
dividing or distributing surface substantially as herein before described.
2nd. In an apparatus for carburetting air heating the hydrocarbon or carburet
mixed with hot water or otherwise by means of a hot water jacket such as T acting in
combination with a helical brush such as M whose office it is to divide or break up
the stream of liquid and facilitate the carburetting of the air as hereinbefore described
with reference to figure 1 of the accompanying drawing.
3rd. In an apparatus for carburetting air for motive power purposes a hydrocarbon
or carburet supply tap such as R in combination with a valve (S) connected with the
governor of the motor in order that the supply shall be automatically controlled and
regulated according to the consumption substantially as hereinbefore described with
reference to figures 1 and 2 of the annexed drawings.
4th. In an apparatus for carburetting air the employment of a valve (B) for
excluding flame in combination with a valve (V) preventing the escape of vapour
substantially as hereinbefore described with reference to figures 1 and 3 of the annexed
drawings.
5th. In a carburetter the combination of the hydrocarbon or carburet distributer R.S.
and the hot water tap or distributer R¹ with a brush b and a helical brush M enclosed
in a hot water jacket T all acting as and for the purpose herein before described with
reference to figure 1 of the accompanying drawings.
6th. The general arrangement and combination of parts forming a carburetter and
comprising a reservoir Z taps or distributers R and R', a brush b, a brush M, a hot
water jacket T a valve V, a valve B and a float L in a vessel C. all arranged and
operating in the manner and for the purpose hereinbefore described with reference to
the annexed drawings.
