We, GEORGE SEAGRAVE, and PIERRE ALCIDE OLIVIER, both of Lime Street
Chambers, 21 Lime Street, City of London, Engineers, do hereby declare the nature
of this invention to be as follows:-
:―
This invention relates to an apparatus, within which, gas or air can be carburated
for lighting or other desired purpose.
We construct a case in which a series of tall pipes are arranged and within this case
we arrange a buoyant or floating body, the internal part of which is provided with
baffle plates alternately arranged from the two sides so that the gas or air passes in a
zigzag manner sidewise from between the partitions, which partitions are provided
with flannel or other fabric forming curtains descending therefrom which are kept
immersed in the hydro carbon or equivalent liquid at whatever height the buoyant
body may be in the vessel.
The buoyant vessel has two or more tubes projecting from the upper part, of larger
diameter than the tubes of the first named vessel, so that a clear space is left between
the tubes for the passage of ordinary air or gas into the vessel and of carburetted gas
or air out of the vessel.
The cover of the vessel is also provided with tubes closed at the ends like the tubes
of the buoyant vessels for said tubes to rise up in when the vessel is full of bydro
carbon liquid to prevent escape or evaporation.
We prefer to place the direct inlet tube outside the first named vessel and by a
branch or bend, lead the gas or air into a tube which reaches to above the level of the
outer vessel so as to be always within the tubes of the buoyant vessel.
Any appliance can be fitted to the buoyant vessel to project through the cover for
indicating the height of the hydro carbon liquid.
We purpose making a liquid tight joint at the charging hole of the hydro carbon
vessel for the attachment of a supply reservoir.

Improvements in or Connected with Apparatus for the Carburation
of Gas or Air.
We, GEORGE SEAGRAVE and PIERRE ALCIDE OLIVIER both of Lime Street, City of
London, 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 apparatus, within which gas or air can be carburated for
lighting or other desired purpose.
The apparatus is composed of an outer vessel as a hydrocarbon container and of an
inner vessel (buoyant) provided with baffle plates on the interior, covered or partially
covered with flannel or absorbent material and with each baffle plate alternately stopped
to form zigzag passages for the gas or air to impinge upon the saturated material to
become enriched, this being enhanced by contact with loose threads hanging across the
zigzag passages as curtains.
The outer vessel has a service pipe leading through the bottom and up within a tube
provided at the top of the inner vessel, there being a clear space between the two
tubes for gas or air, which passes up the inner one, to descend between said inner
tube and an outer one previous to entering the carburetting chamber.
The opposite end of the apparatus is similarly provided with tubes, so that the gas,
enriched by the hydrocarbon, passes up the space between the outer and inner tube,
and then down the inner tube to the outlet.
The outer vessel is provided with a cover, having pipes for the tubes of the buoyant
vessel to ride up and down according to the height of the hydrocarbon liquid in the
container, the flannel being kept immersed whether much or little hydrocarbon be
therein.
The apparatus is constructed as shown in the annexed drawings, Figure 1 being a
longitudinal vertical section and Figure 2 a plan, with the cover removed and with
part of the inner vessel broken away to show the baffle plates more clearly and the
zigzag direction which the gas or air has to travel to become impregnated with the
hydrocarbon, on its way to the outlet.
A is an outer vessel of rectangular shape and B is the gas inlet branch leading, by
the pipe C, into a tube D fitted on the top of the inner vessel E, the upper end of the
tube being closed to prevent escape. F is a cover to the apparatus, hermetically
closed, and G is a tube on the cover also closed at its upper end.
The vessel E is provided with air tight compartments H of suitable number as
shown in the plan view, or it may be with an air tight belt to enable the vessel E to
float in the hydrocarbon liquid and always maintain a liquid tight joint by immersion.
I, I, are the baffle plates which are arranged from the side of the vessel E alternately,
leaving a clearance for the passage of gas or air as it travels through the apparatus.
These baffle plates I, I, are covered on both sides with suitable absorbing material J,
the lower ends of which hang therefrom and act as feeders to the whole of the said
material.

page_text: J¹, J, are loose thread curtains dipping in the liquid hydrocarbon and hanging across
the zigzag passages to break up the gas.
K is another pipe on the cover F closed at top and serves in conjunction with the
tube G as guides for the rising or falling of the tube D) and also of the tube L, the
tube L like the tube D being closed at top, so that the impregnated or enriched gas, as
it leaves the last of the baffle plates 1, passes up the space between the tube L and the
tube M, down which, it descends to the outlet N, from thence to the burner or burners.
P is a screw plug hermetically covering the feeding pipe. Qis also a screw plug
similarly covering the pipe provided for emptying the vessel A.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed we declare that what
we claim is :-
--
The apparatus composed of an outer vessel A as a hydrocarbon liquid container
arranged as described and the inner buoyant vessel E, containing clothed baffle plates I
with alternate side
and for the pe side passages, and the arrangement of pipes U, D, G, K, L, M, all as
