Improvements in Apparatus for Oarburetting Air.
1, EDOUARD BOUCHAUD-PRACEIQ, of 42, Rempart du Midi, Angouleme,
(Charente), France, do hereby declare the nature of this invention to be as
follows:-
My invention relates to simple and compact apparatus for carburetting air to
serve as combustible gas, the apparatus being so arranged that there is no danger
or difficulty attending its use.
For this purpose, I employ a vessel which may be a covered flagon such as is
used for carrying oil; I fix very near its bottom a sheet of wire gauze and on this
I pile a number of small blocks of porous material, such as wood which has been
boiled with alkali, sponge, felt, porous paper, peat, coke or the like, these blocką
being all kept at a little distance apart, by interposed pieces of wire or otherwise.
When the vessel is thus filled up, very nearly to the top I cover the blocks with
a sheet of wire gauze and fix the cover which has through it the usual charging
hole and another hole down which I pass a pipe through both gauzes nearly to
the bottom. The porous blocks being all saturated with the volatile carburetting
liquid, air entering by the charging hole passes through the narrow spaces which
separate the blocks absorbing the vapour and becoming heavier and finally issues
as combustible gas by the pipe which leads from the bottom.
A small carburetting apparatus of this kind may be arranged to supply one lamp
or several lamps. Vessels niny be employed which have a charging hole at the
top and an outlet from the bottom furnished with a stop cock, this constructing
the outlet for the carburetted air.

improvements in Apparatus for Carburetting Air.
I. EDOUARD BOUCHAUD-PRACHIQ, of 42, Rempart du Midi, Angouleme,
(Charente), France, do hereby declare the nature of this invention and in what
imanner the same is to be performed to be particularly described and ascertained.
in and by the following statement:
-
My invention relates to simple and compact apparatus for carburetting air

page_text: to servo as combustible gas, the apparatus being so arranged that there is no
danger or difficulty attending its use.
For this purpose I employ an apparatus such as I will now describe with refer-
ence to the accompanying drawings.
Fig. 1 is a side elevation; Fig. 2 is a horizontal section, Fig. 3 is a vertical
section on the line 3-3 of Fig. 2; Fig. 4 is a vertical section of a slightly modified
form of the apparatus on the line 5-5 of Figs. 5 and 6; Fig. 5 is a horizontal sec-
tion of this modified form, and Fig. 6 a plan of its top; Fig. 7 is a perspective
view on an enlarged scale of one of the blocks B; Figs. 8 and 9 shew the apparatus
installed for use.
A is a vessel which may be a covered flagon such as is used for carrying oil. I
fix very near its bottom a sheet of wire gauze C and on this I pile a number of
small blocks B of porous material, preferably wood, which have been boiled with
alkali, but I may also make them of sponge, felt, porous paper, peat, coke or the
like. These blocks are built in the vessel like bricks and are all kept at a little
distance apart from each other, so as to form numerous channels and to allow free
circulation of air throughout the whole pile. The blocks may be kept apart by
interposed pieces of wire, or as an alternative each block may have wrapped round
it a band c. Only one such band is necessary if the blocks with their bands are
arranged as shewn in Fig. 5.
.
When the vessel is thus filled up very nearly to the top I cover the blocks with
a sheet of wire gauze C and fix the cover which has through it the usual charging
hole D and another hole E (Figs. 1 and 3); the former serves to permit access
of air to the apparatus, while down the hole E I pass a pipe F through both
gauzes nearly to the bottom of the vessel. This pipe forms the exit for the
carburetted air and may with advantage be cut obliquely at the end as shewn in
Fig. 4, so that should liquid of condensation occupy the bottom of the vessel; the
mouth of the pipe may not be closed causing an irregular flow of the carburetted
air.
The porous blocks are all saturated with the volatile carburetting liquid, care
being taken that no liquid remains unabsorbed; blocks of wood prepared in the
manner described will absorb a volume of liquid nearly equal to their own volume.
The air which enters the apparatus at D passes through the narrow spaces between
the blocks, absorbs the vapour of the volatile substance and the mixture becoming
specifically heavier descends to the bottom of the vessel whence it issues through
the pipe F.
The pipes D and E may be bent as shewn in Figures 4 and 5, so as to form a
handle.
'
The pipes from several apparatus may be connected so that the vessels may be
used in series, a fresh vessel being substituted for the exhausted vessel when
required.
In an installation the exit pipe E is connected with a pipe G (Fig. 8) of the
existing service. In order to start the flow by charging the siphon thus formed,
the vessel may be inverted so that the carburetted air may flow by reason of its
specific gravity. The carburetted air being specifically heavier than air, continues
to flow down the pipe G, and to tho burners which may be of any kind including
regenerative burners, incandescence burners, and others. The size of the carburet-
ting vessel as shewn in Fig. 9 should be suited to the extent of the installation
this vessel being filled with absorbent material and charged with volatile car-
buretting substance from time to time.
The connection with the service pipe may be made at the bottom of the vessel,
instead of being connected at the top of the vessel, to a pipe passing down through -
tho material to the bottom of the vessel.
The sysem is independent of heat; on the contrary, the evaporation which takes
place in the vessol chills the gas thus avoiding liability to accidents and ensuring
the descent of the gas by increasing its specific gravity.

page_text: Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I declare that what I
claim is:-
1. An apparatus for carburetting air consisting of blocks of wood which has
been boiled with a solution of alkali, or of other porous material, these blocks
being saturated with a volatile carburetting substance and arranged in a vessel
provided with an inlet for air and an outlet for carburetted air from its bottom
substantially as described with reference to the accompanying drawings.
2. In apparatus such as is above referred to the use of blocks having bands
wrapped around them substantially as and for the purpose set forth.
