We, JAMES PARKES, and JOSEPH PARKES, both of 116 Alma Street, Aston in the
county of Warwick Manufacturers do hereby declare the nature of our invention to
be as follows:-
This invention relates to improvements in the construction and arrangement of
apparatus for the enriching of the illuminating power of ordinary coal gas, by mixing
therewith the vapours of hydro-carbon substances; whereby the amount of the supply
of carburretted or enriched gas is regulated at will; and also the more useful and
convenient disposing of the parts of the arrangement; and being to a great extent,
further improvements and modifications of the inventions for which letters patent
have been granted to the first named of us viz. James Parkes, Nos. 454, 1886, and
2950, 1886.
We use a carburretting vessel having a supply pipe formed upon its upper part,
and upon the interior part of which are holes for the passage of the gas supply
from the main into the carburretting vessel, or otherwise more directly to the outlet
pipe, and thence to the burner or burners. An internal outlet pipe is provided the
one end of which is placed opposite to a hole in the supply pipe, so that the tendency
of the gas issuing from such a hole would be, to pass at once into the outlet pipe, and
thence to the burner or burners with little or no hydrocarbonization.
We further provide in the supply pipe an outlet for gas, that it may pass into the
vessel in order to be carburretted before passing thence through the outlet pipe
beforementioned to be consumed.
We further provide means for the opening and closing of the outlet, by inserting a
plug tap or a screw tap, or other convenient method; for instance, we may insert from
the upperside of the vessel directly over the hole in the supply pipe we may wish to
deal with, a screw plug, the inner end of which may have for a short distance, half or
thereabouts of its diameter removed, so that about half a turn of such plug (on the
outside) would open or close the supply passage.

page_text: In some instances we may make the regulating tap or plug, having three ways,
so that the entire supply may be carburretted, or, partly so, or, little or none
carburretted.
From the carburretting vessel the outlet pipe may lead to the burner similarly as
those described in the above quoted specifications, or, in some cases, I should prefer
to carry the outlet pipe to the bottom of the vessel, and near thereto place a threeway
tap having upon one side an heating burner which is sufficiently close to and under-
neath the vessel to heat or melt the contents of the latter in order to give off their
vapour, while upon the other side, the pipe is carried to the illuminating burner or
burners.

COMPLETE SPECIFICATION.
Improvements in Carburretting Apparatus.
We JAMES PARKES, and JOSEPH PARKES both of 116 Alma Street, Aston, in the
county of Warwick Manufacturers 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 :-
This invention relates to improvements in the construction and arrangement of
apparatus for the enriching of the illuminating power of ordinary coal gas, by mixing
therewith the vapours of hydro-carbon substances, whereby the amount of the supply
of gas to be carburretted or enriched is regulated at will, and also the more useful
and convenient disposing of the parts of the arrangement; and being to a great extent
further improvements and modifications of the inventions for which letters patent
have been granted to the first named of us, viz. James Parkes, Nos. 454, 1886, and
2950, 1886.
We use a carburretting vessel having a supply pipe formed upon its upper part, and
through the interior part of which, holes are made for the passage of the gas supply.
from the main, into the carburretting vessel, or, otherwise inore directly to the outlet
pipe, and thence to the burner or burners. An internal outlet pipe is provided the
one end of which is placed opposite to a hole in the supply pipe, so that the tendency
of the gas issuing from such a hole would be to pass at once into the outlet pipe and
thence to the burner or burners with little or no hydrocarbonization.
We further provide in the supply pipe an outlet, or passage for gas, so that some
may also pass into the vessel in order to be carburretted, before passing thence through

page_text: the outlet pipe to be consumed. We further provide means for the opening or
closing of the outlet, by inserting a plug tap or screw tap, or other similar convenient
method; for instance we may insert from the upperside of the vessel directly over the
hole in the supply pipe we may wish to deal with, a screw plug, the inner end of
which may have for a short distance, half or thereabouts of its diameter removed, or,
what would be equal, a hole drilled through its diameter, so that about half a turn of
such plug or tap, would open or close such passage.
In some instances we may make the regulating tap or plug, having three ways,
so that the entire supply may be non-carburretted, or, partly so, as it may be
desired.
From the carburretting vessel the outlet pipe may lead to the burner similarly as those
described in the above quoted specifications, or, in some cases I should prefer to carry
the outlet pipe to the bottom of the vessel, and near thereto place a three-way tap
having upon one side an heating burner, which is sufficiently close to and underneath
the vessel, to heat or melt the contents of the latter in order to give off their vapour,
while upon the other side, the pipe is carried to the illuminating burner or burners.
Having now described the nature of this our said invention we will proceed to more
particularly describe and ascertain the manner in which it may be carried out, having
reference to the accompanying illustrative sheet of drawings, upon which are figures
and letters of reference.
Fig. 1, is a sectional view of one form in which this our invention may be
arranged. Fig. 2, is a sectional view of a modified form of this our invention.
Fig. 3, is a sectional view of a further modification of this our invention. Fig. 4 is
an enlarged detail of one part of Figs. 1, & 2. Figs. 5, 6, & 7 are enlarged detailed
views of the three various positions in which the regulating tap, Fig. 3, may be used.
Similar letters throughout the various views indicate the same part, thing, or
purpose.
In Fig. 1, a, is the carburretting vessel, b, is the raw gas supply pipe, c, is the
outlet pipe, d, is the passage leading from the pipe & directly over the pipe c; e, is
the passage from the pipe b, to the interior of the vessel a; is the regulating tap or
plug, having a passage made through its diameter corresponding to the passage e;
9 is an extended outlet pipe conveying the mixed or unmixed gas from the outlet
pipo c, to the burner or burners h, & i; i, is the heating burner, j, the heating burner
tap or regulator, k, is the opening through which the vessel may be charged with the
carbonaceous substances by the removal of the plug l.
It will be seen from the direction of the arrows, (see also Fig. 4) that the raw gas
passes from the main through the supply pipe b, a very large portion of it passing
directly through the passage d into the pipe c, and thence to the burners; with the
passage in the plug or tapf however, being placed fair or open to the passage e,
a portion of raw gas passes therethrough into the vessel a, and having become
impregnated with the vapours therein, then finds its way in the direction of the
arrow m into the outlet pipe c, passing on to be consumed. Should it be desirablo
however to still further limit the amount of gas passing through the passage e, the
plug may be turned round and so regulate or cut off such supply.
e,
from
In Fig. 2, the arrangement is modified in order to allow of the raw gas being
supplied through the bottom of the vessel a. Provision is here also made for some
portion of the raw gas to pass into the vessel a, through the passage or hole
the supply pipe b, in order to be carburretted, and then to pass on in the direction of
the arrow m through the plug f, to be consumed, the said plug acting as before if
required to cut off such flow from passing through. We find that when the plug is
turned round so as to close the passage e¹, Fig. 2, there is little or no tendency for the
gas in its passage through the supply pipe b, to enter the hole e, but passes on into
the outlet pipes c, g, &c.
Fig. 4 is a detail of Fig. 2, but in this case the direction of the arrows shewn would
be reversed.
A further modified arrangement of this our invention is shewn in Figs. 3, 5, 6, & 7.
It will be here seen that the plug or tap f is made not only to regulate the supply of

page_text: raw gas to be carburretted, but also to control the entire supply, by reason of its being
made after the manner shewn in detail in Figs. 5, 6, & 7, Fig. 5 shewing a direct
open communication between the supply pipes b, and also an open passage e,
leading to the vessel a. The gas which passes through the passage e, to be carburretted
afterwards finds its way into the outlet pipe g, in the same manner before described,
in the direction of the arrow m. Fig. 6 shews how, by turning the plug round a little
way, the to be carburretted is cut off, leaving the passage open for raw gas to pass
freely into the outlet pipe g. Fig. 7, shews a further position of the plug where the
supply is entirely cut off.

The details of the arrangements of the illuminating and heating burners, and the
pipes leading thereto may be somewhat modified to suit requirement, but generally
they would be adopted and used as shewn.

Having now particularly described and ascertained the nature of this our said
invention and in what manner the same is to be performed, we declare that what we
claim as our invention of Improvements in carburretting apparatus is:
1st. The general arrangement and combination of the parts of the said apparatus
herein before described and illustrated in Figs. 1 & 4, of the accompanying drawings,
that is to say The combination with the supply pipe to a carburretting vessel, of an
outlet pipe, and also a direct gas passage from the supply pipe to the carburretting
vessel, which passage is controlled at will by a plug or tap, in the manner and for the
purposes specified.
2nd. The modification herein described and illustrated in Figs. 2 & 4, that is to say,
The combination with the supply pipe to the carburretting vessel, of an outlet pipe,
and also a gas passage from the supply pipe to the carburretting vessel, together with
a passage from the carburretting vessel to the outlet pipe, which passage is controlled
at will by a plug or tap in the manner and for the purposes specified.
3rd. The modification herein described and illustrated in Figs. 3, 5, 6, & 7, that is
to say, The combination with the supply pipe to a carburretting vessel, of an outlet
pipe, and also passages from the supply pipe to the outlet pipe and also to the carbur-
retting vessel, being formed and controlled by means of a plug or tap, which is capable
of allowing, simultaneously a communication to the outlet pipe, and also to the carbur-
retting vessel, (see Fig. 5) or, of communicating only with the outlet pipe, (see Fig. 6)
or, of completely shutting off the gas supply, each and all in the manner and for the
purposes specified.
