Improved Construction and Arrangement of Carburetting Apparatus.
I GEORGE SEAGRAVE of Chelsea Gardens, Chelsea, in the county of Middlesex,
Engineer, do hereby declare the nature of this invention to be as follows :-
This invention is an improved carburetting apparatus for the purpose of giving a
very great illuminating power to fluids, air, or gas.
This apparatus is composed of two chambers, one above the other of suitable form,
serving, one as receiver, and the other as automatic feeder of the carburetting fluid.
The upper or circular receiving chamber is placed above a rectangular chamber
which contains a grating supporting wicks. These wicks at their lowest part dip into
the carburetted liquid which rises to the bottom of the feeding tube. This tube is
surmounted by a funnel with slots. In this funnel is a movable cone which is hollow
and also provided with slots which can be placed opposite those of the funnel by
turning the conical cock from the exterior by means of the square of a rod.
The air or the gas contained in the lower chamber cannot pass into the upper
chamber except by the tube which dips into the carburetting fluid; as soon as it
comes out of the carburetting fluid the air or the gas in passing into the chamber
forces the said carburetting fluid to descend more or less rapidly by the slot always
open (during the working of the carburetter) in the tube and the chamber so as to
immerse anew the tube and thus to stop automatically the supply into the lower
chamber. By this means the level of the carburetting fluid is always the same in said
chamber the feeding being in equal proportion with the required quantity of
carburetting fluid. The emptying of the chamber is effected by a draw off cock.
To fill the receiving chamber the cock is completely closed, to prevent overflowing
of the chamber, then the plug which forms a tight joint by its hydraulic packing, is
unscrewed.

page_text: When the desired level is attained the plug must be closed and the cock gradually
opened (the cock should always be closed during the filling of the chamber) until the
normal level of immersion of the wick is secured. To prevent all escape by the cock,
its rod is fitted with a ring, upon which rests a screwed socket forming a cup which
is pressed strongly against the ring and which serves as a support to the screwed cap
in form of a bell which is placed on the top of the square of the rod.
A glass level index tube serves to note the level of the liquid in the chambers.
The air or the gas desired to be carburetted finds its way into the chamber by the
tube and thus becomes enriched by coming into divided contact with the carburetted
liquid, with which the wicks are saturated, and leaves the chamber by means of a
tube to the burner or burners.

Improved Construction and Arrangement of Carburetting Apparatus.
I GEORGE SEAGRAVE of Chelsea Gardens, Chelsea, in the county of Middlesex,
Engineer do hereby declare the nature of this invention which has been communicated
to me from abroad by Paulin Fougeron Junr. of Paris, France and in what manner
the same is to be performed to be particularly described and ascertained in and by the
following statement :-
This invention is an improved carburetting apparatus for the purpose of giving a
very great illuminating power to the fluids air or gas.
This apparatus is composed of two chambers, one above the other of suitable form
serving, one as receiver and the other as automatic feeder of the carburetting fluid.
The figures of the drawings annexed represent the different parts comprising my
improved carburetting apparatus.
The figure 1 is a front elevation and the Figure 2 is a plan from the top of my
carburetting apparatus.
The Figures 3 and 4 are vertical sections through the lines 1 2 3 4 and 5 6 of the
Figure 2.
Figure 5 represents the automatic feed cock worked from the outside.
In these figures the same letters designate the same part.
The circular receiving chamber a is placed above a rectangular chamber b which
contains a grating 6 supporting the wicks c these wicks c at their lowest part dip
into the carburetted liquid which rises from the bottom of the feeding tube f. This
tube is surmounted by a funnel e with slots e¹; in this funnel is a movable cone e¹¹
which is hollow and also provided with slots which can be placed opposite those of the
funnel by turning the conical cock from the exterior by means of the square f¹ of the
rod f¹¹.
The air or the gas contained in the chamber b cannot pass into the chamber a
except by the tube d which dips into the carburetting fluid; but as soon as it comes
out of the carburetting fluid the air or the gas in passing into the chamber a forces
the said carburetting fluid to descend more or less rapidly by the slot el (always open
during the working of the carburetter) in the tube f and the chamber 6 so as to
immerse anew this tube d and thus to stop automatically the supply into the chamber b.
By this means the level of the carburetting fluid is always the same in the chamber b
the feeding being in equal proportion with the required quantity of carburetting fluid.
The emptying of the chamber b is effected by a cock l.
To fill the receiving chamber a, the cock ell is completely closed to prevent the
overflowing of the chamber b, then the plug a¹ is opened which plug otherwise forms
a light joint by its hydraulic packing.
When the desired level is attained the plug a¹ must be closed and the cock ell
gradually opened (the cock ell should always be closed during the filling of the
chamber a), until the normal level of immersion of the wicks c is secured. To
prevent all escape by the cock its rod f" is fitted with a ring k upon which rests a

page_text: screwed socket m forming a cup which is pressed strongly against the ring k which
serves as a support to the screwed cap ¹ and is in form of a bell placed over the top
of the square of the rod f¹¹.
The glass level index tubes i serve to note the level of the liquid in the
chambers, a, b.
The air or the gas desired to be carburetted finds its way into the chamber 6 by
the tube and thus becomes enriched by coming into divided contact with the
carburetted liquid with which the wicks c are saturated and leaves the chamber by
means of the tube h.
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. In a carburetting apparatus to give to air or gas a great illuininating power,
the combination of two closed chambers, one over the other, one as a receiver and
the other as a carburetter, the automatic feeding of which is effected by means of
a cock worked from the outside as described and represented.
2. The arrangement of the cock for the automatic feeding represented by Figure 5
allowing the communication between the two chambers to be free or arrested during
the working or suspension of the action of the apparatus as represented.
3. The combination of the two chambers a and b, with the cock e¹ and the air
tube d, for the purpose of maintaining a fixed level shown by the glass level
index tube and a regular and constant carburation during the working of the
carburetter as described and represented.
