Improvements in Carburettors.
We, EDOUARD ALEXIS VIVINUS and AUGUSTE JULES HECIT, both of Schaerbeck-
lez-Bruxelles, Belgium, Engineers, 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 improved carburettor wherein fresh liquid can be
continually exposed to the air to be carburetted; which possesses in a small
volume a very large carburetting surface, and which allows of an extremely easy
regulation of the delivery of the carburetting liquid.
The invention comprises two superposed receptacles, one forming the distributor
of the carburetting liquid and the other the carburetting chamber proper, the
two receptacles communicating throughout their entire length by means of a
strip of felt or equivalent material, part of which is situated in the liquid dis-
tributing receptacle whilst another part passes into the carburetting chamber, the
latter portion of the felt or the like being cut into small strips, or unravelled or
otherwise treated so as to increase the carburetting surface and to extend the felt
or the like to all parts of the carburetting-chamber.
Both receptacles have preferably contracted extensions forming a tightening-
collar and by means of which one of the receptacles is fixed or fitted in the other;
securing bars, capable of being brought towards one another by means of screws
or other tightening devices, being arranged outside the said collars so as to be
able to more or less compress the part of the band of felt or the like constituting
the communication between the two receptacles and thus regulate the delivery of
the carburetting liquid.
The accompanying drawing represents a carburettor constructed in accordance
with our invention,
Fig. 1 being a front view, and
Fig. 2 a vertical section.
The carburettor consists of a tubular receptacle A open underneath along its
entire length and having an extension formed of two spring-like sides a a capable
of being moved towards each other. The receptacle A is by means of this exten-
sion introduced or fitted into a corresponding extension 6 6 formed on the upper
part of the second receptacle B which is of larger section and open at the top.
The upper receptacle A is closed at its two ends and is furnished with an inlet-
tube T for the liquid whilst the lower receptacle B is provided at one end with
an opening E for the introduction of air and at the other end with a discharge
tube S leading to the motor to be driven, or elsewhere as required.
The sides bb are preferably covered by two bars or plates c c which, as well
as the extensions a a and b b are pierced with holes, to allow of the introduction of
the tightening screws V.
The receptacles A and B intercommunicate by means of a strip of felt or the
like D placed between the sides or strips a a of the extension of the upper recep-
tacle A and extending the entire length of the two receptacles. The part of the
strip of felt or the like in the lower receptacle is divided by numerous cuts or is
unravelled or otherwise treated and is caused to extend to all parts of this recep-

page_text: tacle B as shewn in Fig. 2. The part of the strip of felt or the like between the
collars a a, b may be more or less compressed by means of the plates CC' and the
tightening screws V.
The operation of the apparatus is as follows:-
The carburetting liquid is delivered into the distributing receptacle A by the
tube T and is absorbed along the entire length of this receptacle by the strip of
felt or the like D) which becomes moistened down to and includes the part cut or
otherwise treated and well spread out in the lower receptacle B.
The air, sucked in by the motor, enters at E, is carburetted by meeting on its
passage the felt 1) impregnated with the liquid and reaches the pipe S as a gas.
Air, therefore, has only to be added more or less to this gas to obtain an explosive
mixture suitable for driving a motor. The desired delivery of carburetting
liquid is attained by screwing the screws V and the plates C C¹ bb, a a more or less
tightly against the band of felt D.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed we declare that what
we claim is:-
1. A carburettor consisting of two superposed receptacles, one distributing the
carburetting liquid and the other forming the carburetting chamber, the two recep-
tacles intercommunicating along their entire length by means of a strip of felt or
the like part of which passes into the liquid distributing receptacle
and another part into the carburetting chamber, the latter part being
cut or divided or unravelled and spread out so as to extend to all parts of the
carburetting chamber and another part of the said strip being situated between
tightening-plates so as to regulate the delivery of the carburetting liquid by more
or less compressing the strip substantially as specified.
2. A carburettor consisting of two superposed tubular receptacles (A) and (B),
one open below and the other open at the top, the two receptacles being fitted one
within the other by means of contracted extensions (a a, b b) between which is
placed a strip of felt (D) or the like which establishes communication between
the two receptacles, substantially as described and shown in the accompanying
drawing.
3. A carburettor consisting of two superposed receptacles (A) and (B) fitted one
within the other by means of tightening-collars (a a, b b) and intercommunicating
by means of a strip of felt or the like cut or divided or unravelled and spread out
at its lower end, two tightening plates or bars (C C¹) being applied to both sides of
the tightening-collar and being traversed by screws (V) to more or less compress
the part of the strip of felt or the like between the collars.
4. The improved carburettor constructed arranged and operating substantially
as described and shewn in the accompanying drawing.
