PROVISIONAL SPECIFICATION.
Improvements in and connected with Gas Carburetting Apparatus.
I, JACOB ORMEROD of 68 Bury New Road Higher Broughton Manchester in
the County of Lancaster, Lt.-Colonel United States Army (retired), do hereby
declare the nature of this invention to be as follows:-
:-
This invention relates to apparatus and means for carburetting illuminating gas,
its principal objects being the use of a carburetting liquid which will not flash
at or below the temperature prescribed by the existing Petroleum Act, and the
prevention of condensation of the carburetting liquid in the service pipes.
The liquid which I use for the purpose of my invention consists of an admixture
of benzine from petroleum, having a S.G. of about 720 to 750 and rosin spirit
having a S.G. of about 800 in the proportions of about 2 parts of benzine to about
1 part of rosin spirit.
a
The carburetting apparatus which I use for the more effective combination of
the carburetting liquid with the gas, consists of a metallic chamber, to the lower
portion of which the liquid is admitted in proportion to its evaporation, by
ball-cock or otherwise. This part of the chamber is divided by radial perforated
partitions, through which wires are threaded for the suspension thereon of wicks
or the like, the lower ends of which dip into the carburetting liquid. The gas to
be enriched is also admitted to this part of the chamber, and by contact with
the wetted wicks becomes supercharged with the vapours of the liquid. Above
this chamber, there is a second chamber consisting of an annular part and a
central circular part. The annular part is divided by perforated radial partitions
as in the case of the lower chamber, and, as in the lower chamber, one of the
partitions is replaced by a solid plate. The spaces between the perforated
partitions are lightly packed with cotton wool or other suitable and similar
material and from them, or some of them, gutters lead into the liquid in the
lower chamber. The central part of the chamber contains a circular pipe the
inner circumference of which is radially perforated, and this part of the chamber
is also lightly packed with charcoal or some similar material, in pieces.
The saturated gas, rising from the lower chamber into one of the spaces in the
annular part of the upper chamber next to the solid division plate, passes through
the cotton wool in all the spaces until it reaches the last, from which there is an
outlet to the perforated pipe, through which it passes into the mass of charcoal.
By these devices the saturated gas is relieved from any free globules of the
carburetting liquid, and a practically permanent mixture is obtained.
The carburetted gas may pass from the charcoal mass direct to the service pipes,
but I prefer to allow it to pass to a third chainber from which it may be led to the
service pipes.

I, JACOB ORMEROD of 68 Bury New Road, Higher Broughton, Manchester, in
the County of Lancaster, Lt.-Colonel, United States Army, (retired) 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 apparatus and means for carburetting illuminating gas,
its principal objects being the use of a carburetting liquid which will not flash at
or below the temperature prescribed by the existing Petroleum Act, and the
prevention of condensation of the carburetting liquid in the service pipes.
The liquid which I use for the purpose of my invention consists of an admixture
of petroleum "benzine" or petroleum naphtha, having a S.G. of about 720 to 750
and rosin spirit, having a S.G. of about 800 mixed in about the proportions of
2 parts of the petroleum naphtha, to 1 part of the rosin spirit.
The carburetting apparatus which I use is illustrated by the accompanying
drawings in which :-
Figure I is a sectional side elevation.
Figure 2 is a transverse section along the line - and Figure 3 is a similar
section along the line y-y Figure 1.
It consists of the tank A, the supply cistern B, and the carburetter C, together
with the necessary pipes and taps.
The illuminating gas arrives from the main through the pipe a which communi-
cates with the lower part of the carburetter, from which it finally issues, enriched,
by the pipe b.
The supply of the carburetting liquid is contained in the tank A, whence it
flows through the pipe c to the supply cistern B, the outlet of the pipe being
controlled by the ball cock d, so that a constant level is maintained in B, and in
the carburetter C, with which the cistern communicates by the pipe e.
cistern should be closed with a tight fitting cover to prevent the evaporation of the
liquid.
The
The carburetter C is divided into three parts, D. E. F. by diaphragms fg.
The lower part D is divided by radial partitions all of which except one, h', are
perforated. Through the upper part of the chamber, wires i are threaded for the
suspension thereon of wicks or the like, the lower ends of which dip into the
carburetting liquid. The wicks are maintained in a constant damp condition by
capillary action, and present a large area of wetted surface to the gas which enters
at a into the division next the blank partition 1, and passes through all the
perforated partitions in turn until it arrives at the other side of the blank partition,
near which there is an opening k in the diaphragm f, through which the gas passes
into the part E of the carburetter.
This part of the carburetter consists of an outer annular part and an inner
circular part. The outer annular part is radially divided as in the part D, by
radial partitions, all of which except one, l', are perforated. The spaces between
the partitions are lightly packed with cotton wool, or other similar substances, and
from them, or some of them, gutters or pipes m lead into the liquid in D so as to
drain away any condensed liquid. The central part of the chamber contains a ring
pipe G, which is radially perforated in the manner of a "ring gas burner" and
which has only one open end, in communication with the division of the annular
part which is on the opposite side of the solid partition to that on which the
inlet is placed. The gas thus passes from the annular space into the circular
space through the pipe G the perforations of which spread or diffuse it. The
circular part is lightly packed with lumps of charcoal or other similar material.

page_text: The diaphragm g is solid above the annular part and perforated above the circular
part of E, whence the enriched gas passes into the open part or chamber F and
finally issues through the pipe b.
For the purpose of cutting out the carburetter for repairs and other purposes,
a bye-pass n may be provided.
To avoid confusion the perforated partitious wires and packing materials are not
represented in Figure 1.
The saturated gas, rising from the lower chamber into one of the spaces in the
annular part of the upper chamber next to the solid division plate, passes through
the cotton wool in all the spaces until it reaches the last, whence it passes by the
ring pipe G into the mass of charcoal lumps. By these devices the saturated gas
is relieved from any free globules of the carburetting liquid, and a practically
permanent gaseous mixture is obtained.
The carburetted gas may pass direct from the charcoal to the service pipes, but
I prefer to allow it to pass first, into the third chamber F, as illustrated by the
drawings.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The hereinbefore described means for carburetting illuminating gas which
consist in passing the gas in contact with wicks and the like, saturated with a
liquid composed of about 2 parts of petroleum naphtha aud one part of rosin spirit,
and thereafter through cotton wool, charcoal and the like materials, substantially
as hereinbefore described with reference to the accompanying drawings.
2. A gas carburetter consisting essentially of two chambers the first of which is
divided by perforated partitions and contains wicks suspended on wires or the like
and the second of which has an annular part divided by perforated partitions, and
a central part communicating therewith; constructed and arranged substantially
as and for the purpose hereinbefore described and as illustrated by the accom-
panying drawings.
3. Apparatus for carburetting illuminating gas, constructed arranged and
operating substantially as herein before described and as illustrated by the accom-
panying drawings.
