I, EDOUARD BOUCHAUD-PRACEIQ, of 42, Rempart du Midi, Angouléme, (Char-
ente), France, Mechanic, do hereby declare the nature of this invention to be as
follows:-
My invention relates to apparatus for carburetting air so as to supply.combus-
tible fluid for working engines or other purposes, the chief object of my invention
being simple means of regulating the amount of carburation.
or
are
;
For this purpose, in an air tight vessel I superpose a number of porous plates
or slabs, which may be of felt, porous wood or other suitable material and may
have perforations through them. These slabs or plates are kept
slightly apart by studs otherwise so that there
thin passages
for air between each plate or slab and that above it. Through
the middle of all the plates or slabs is a hole down which can be lowered a collect-
ing tube which is closed at the bottom, but just above the bottom has lateral open-
ings preferably in the form of horizontal slits. The vessel is covered with wire
gauze or perforated metal allowing air to pass down and circulate through the
interstices between the plates or slabs which are impregnated with the carburet-
ting liquid. As the collecting tube is more or less lowered it receives through the
openings at its lower end, air which has passed through a greater or less depth
of the slabs or plates and has thus received a greater or less degree of carburation.
The tube may be flexible so that it can be bent over the top of the vessel and con-
nected to the pipe leading the carburetted air to its place of consumption.
Instead of a single collecting tube there may be several vertical tubes all
branching from a main horizontal tube at the top, and these can all be simul-
taneously raised or lowered by a screw or otherwise.

I, EDOUARD BOUCHAUD-PRACEIQ, of 42, Rempart du Midi, Angouléme, (Char-
ente), France, Mechanic, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
My invention relates to apparatus for carburetting air so as to supply combus-
tible fluid for working engines or other purposes the chief object of my invention

being simple means of regulating the amount of carburation as I shall describe
referring to the accompanying drawings."
Fig. 1 is an elevation partly sectional and Fig. 2 is a plan of one form of car-
buretting apparatus according to my invention. Fig. 3 is a section and Fig. 4
is a plan drawn to an enlarged scale of the regulating tube.
Fig. 5 is a section and Fig. 6 is a plan of the perforated plates.
Figs. 7 and 8 are respectively longitudinal and transverse sections and Fig. 9
is a plan of a carburetting. apparatus suitable for a motor car. Fig. 10 is an ele-
vation partly sectional shewing a flexible tube for delivery of the carburetted air.
Referring first to Figs. 1 to 6 inclusive, A is an air-tight vessel containing a
number of superposed porous plates B which may be of felt, wood or other suit-
able material separated by small ribs so as to leave thin spaces a between the plates.
On the top of the vessel A is a perforated cover b, and through it and through all
the plates is a passage in. which can be moved up and down a tube C closed at
the bottom but having at its lower end lateral holes or preferably slits das shewn
in Figs. 3 and 4. The porous plates B may be perforated with a number of small
holes e as shewn in Figs. 5. and 6.
The plates being impregnated with carburetting liquid the tube C. is, intro-
duced to greater or less depth according to the degree of carburation desired.
Air drawn by a pump or other suction appliance passing through the holes of the
cover 6 descends through the plates B to the depth of the slits at the lower end
of the tube C which it enters in a condition more or less carburetted according as
the tube C is pushed more or less down through the plates. As the liquid in the
upper plates, becomes consumed the tube C is from time to time pushed down so
as to maintain the same degree of carburation.
.
As shewn in Figs. 7 and 8 perforated porous plates E are superposed in an air
tight vessel D, and have several perforated tubes passing through them, each
of these tubes having fitted to slide in it a tube G with slits at its lower end as
previously described with reference to Figs. 3 and 4. All the tubes G and the
central tube G¹ communicate with a main tube H for passage of the carburetted,
air. In order to move the tubes G up or down there is a guide tube I fixed to the
bottom of the vessel, this tube being internally screw-threaded at its upper part.
A screw spindle J which can be turned by a hand wheel K being engaged in the
thread of the tube I, serves to raise and lower the tubes G and G.
As shewn in Fig. 10 the adjustable tube is attached to a flexible-metallic tube.
which can be bent in the direction desired..
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
A carburetting apparatus consisting of a number of superposed perforated porous
plates separated by thin spaces, down through which passes a tube having lateral
openings at its lower end, or several such tubes which can be raised or lowered
and communicate with a pump or other suction appliance, substantially as and
for the purpose set forth.
