1, ARMAND PEUGEOT of Valentigney (Doubs) France, Manufacturer, do hereby
declare the nature of this invention to be as follows:-
This invention has for ite object to remedy the objections attendant on the use
of the apparatus now employed for carburetting air to be supplied to hydro-carbon
gas engines and it consists of a novel system of carburetter which is based on the
principle of volatilization by capillary surfaces.
The apparatus of my invention will be readily understood by reference to the
accompanying drawings wherein
Figure represents a vertical section of one arrangement of the apparatus
consisting of a cylindrical receiver containing a cylindrical diaphragm of capillary
material which is traversed by the air.
Figure 2 is a section of a rectangular receiver containing vertical parallel plates
of capillary material the number and thickness of which may be regulated according
to requirements.
Figure 3 is a section of a cylindrical carburetter having cylindrical partitions of
capillary material concentrically disposed with sheet iron baffles F for prolonging
the passage of the air, which in this example does not traverse the capillary
material but becomes carburetted by flowing along the surfaces which are
impregnated with liquid hydrocarbon. The course of the air is indicated by the
arrows.
Figure 4 is a horizontal section of a carburetter of rectangular form in which
the air follows the course indicated by the arrows and becomes saturated with
hydrocarbon vapours by impinging upon capillary plates arranged in quincunx
order.
Figures 5 and 6 represent respectively a sectional elevation and plan of a
carburetter in which the capillary surfaces are of spiral form around which the
air is forced to flow the extent of capillary surface being regulated by the number
of spirals.
My apparatus is constructed as shewn of a receiver A containing one or more
diaphragms of capillary material B. The receiver is provided with an air
admission orifice C, air exit orifice D, and a liquid inlet passage E. The capillary
diaphragm B being constantly immersed in an invariable quantity of liquid the
latier rises by capillarity in the diaphragm so as to present surfaces constantly
impregnated with hydrocarbon by contact with which the air becomes carburetted
either by traversing the diaphragm of capillary material in a state of extreme
sub-division or by licking the capillary surfaces arranged as baffles to the passage
of the air.

page_text: By this means I obtain as perfect a carburetting action as possible without any
liquid being carried off and thereby obtain an intimate mixture of carburetted air
with atmospheric air. By this means fouling of the valves of the engine and
premature explosions are avoided, besides obtaining economy of liquid and great
regularity of working of the engine.
The composition of the capillary diaphragm would vary according to circum-
stances. It may consist of a hair pad wrapped upon wire cloth but I may use any
other materials possessing capillary properties, such as for example hemp, silk,
cotton, animal hair or vegetable hair, tampico, piassava, ramie, wadding, felt,
ground wood, fabrics, etc.
In the drawing I have supposed the liquid to be maintained at a constant level
by any suitable means.
The carburetted air should on its exit from the apparatus be mixed with a
certain amount of pure air which would be supplied by a cock not shewn.
It will be evident that the forms, details, accessories, materials, and dimensions
of the several parts of which the apparatus is composed may be varied without in
any way departing from the principle of the invention.

I, ARMAND PEUGEOT of Valentigney (Doubs) France, Manufacturer, 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 an apparatus for carburetting air for supplying
hydrocarbon gas engines and it consists of a carburetter in which the liquid is
volatilized by capillary surfaces arranged so as to expose an extended surface to
the air passing through the apparatus as hereafter described with reference to the
drawings accompanying the Provisional Specification wherein Figure 1 represents a
vertical section of a carburetter having a cylindrical diaphragm of capillary
material and Figure 2 is a sectional perspective view of a carburetter containing
vertical parallel slabs of capillary material through which the air passes.
Figure 3 is a section of a carburetter having concentric cylindrical partitions of
capillary material alternated with sheet iron baffles. Figure 4 is a horizontal
section of a carburetter having parallel plates of capillary material and Figures 5
and 6 are a sectional elevation and plan of a carburetter in which the capillary
surfaces are of spiral form.
The apparatus is constructed of a receiver A containing one or more diaphragms
of capillary material B and provided with an air inlet C, carburetted air exit D,
and a liquid inlet passage F. The capillary diaphragm B is in all cases constantly
immersed to an invariable depth in the liquid which is maintained at a constant
level by any suitable means and which ascends by capillarity so that the diaphragm
presents surfaces constantly impregnated with the hydrocarbon liquid.
In Figures 1 and 2 the air is caused to traverse the diaphragm or diaphragms
of capillary material in a state of extreme sub-division and so becomes charged
with the vapour.
In Figures 3 4 5 6 the air does not traverse the capillary material but becomes
carburetted by licking the surfaces of the capillary diaphragms which are saturated
with liquid hydrocarbon, the course of the air being indicated by the arrows, and

page_text: the capillary surfaces being so arranged in combination with the baffles F or in
relation to one another as to cause a prolonged contact of the air with said surfaces
so as to obtain as perfect a carburetting action as possible without any liquid being
carried off.
The carburetted air on emerging from the carburetter should be diluted with
atmospheric air forming an intimate mixture which avoids fouling of the valves of
the engine and premature explosions, and ensures economy of liquid and regularity
of working of the engine.
The capillary diaphragm may consist of a hair pad wrapped upon wire cloth but
other materials possessing capillary properties may be used such as hemp, silk,
cotton, animal hair or vegetable hair, tampico, piassava, ramie, wadding, felt,
ground wood, fabrice, etc.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is
The herein described air carburetter having capillary diaphragms immersed to a
constant depth in liquid hydrocarbon and arranged and combined as described with
reference to the drawings so that the air to be carburetted must pass through
them or in contact with their surfaces as and for the purpose specified.
