I, JAMES PARKES of 234 Burbury Street, Aston, in the county of Warwick
Gas Engineer do hereby declare the nature of my invention for IMPROVEMENTS
IN APPARATUS FOR ENRICHING ILLUMINATING GAS, 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 the construction and arrangement of apparatus for
enriching gas used for illuminating purposes by the admixture of hydro-carbon
vapours therewith; the apparatus being so arranged that the vessel containing the
hydro-carbon substance is heated direct by the illuminating light in the manner
hereinafter stated, without the use of heat conducting plates, or other similar means
now in use.
I will at once proceed to describe this my said invention by the assistance of
the accompanying sheet of drawings, upon which there are figures and letters of
reference.
Like letters refer throughout to the same thing.
Fig. 1, is an elevation of the apparatus, giving an external view, and shewing one
form of pipe f.
Fig. 2 is a sectional view of Fig. 1 also shewing one form of extension of pipe f
to carry extra burner.
a, is the carburretting vessel. At the upper part of the vessel I form the gas
supply pipe b. I find it an improvement in most cases in constructing these vessels
to make the upper part of the vessel by casting it in one with the supply pipe b,
after the manner shewn, also providing the plug and plug hole at c, through which
the hydro carbon substance is passed into the vessel a, In and through the
underneath of the supply pipe b, I perforate a number of holes d, d, and so place
them that the pressure of the gas in the pipe shall tend to force the gas downwards
in the direction of the arrows, ensuring by these means the more complete mixing
of the gas with the hydro-carbon vapours, before its escape to the burners.
end of this pipe at 7 is stopped.
The
Upon the other side of the carburretting vessel I place the outlet pipe e, which is
carried to the lower part of the vessel and thence to the burner or burners by the
curved pipe or pipes f.
I wish it to be noticed that the pipe e is for conveying the enriched gas to the
burners, and also that its position is slantwise to the side of the vessel, opposite to

page_text: and as far as possible from the supply pipe b, thus not only utilizing the heat of
the melted hydro-carbon substance to prevent the clogging of the vapours in the
pipe, but at the same time giving plenty of room from the exit of the pipe b, at d, d,
to the entrance of the outlet pipe e, for the gas to become well mixed with the
vapours of the said hydro-carbon substance.
Instead of carrying only, one pipe f, if I wish to obtain more than one light,
I may carry pipes similarly as shewn by dotted lines at f1, f2, f3 & f4, although
I do not confine myself to the precise shape shewn by these pipes f, f1, f2, f3 & ƒ 4.
I may also further furnish if desired, each or any of these pipes with a tap or
cock at any desired point between the bottom of the vessel and the illuminating
burner.
When adopting the double pipe f & f2 in Fig. 2, the illuminating burners m, n,
would be arranged as shewn at f3, f 4, so that one of the burners shall lie (in plan)
some little distance from under the vessel a, as shown at o, while the burner n is
more or less direct under the said vessel for the purpose of heating it.
The general cock for the regulation of the supply of the gas, may be placed at any
desired point of the main, before reaching the vessel, or, it may form the connection
between the vessel and the said main; the end of the supply pipe b, being provided
at k with an internal or external screw thread or otherwise, to suit attachment to
controlling tap or other gas fitting.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed I declare that what
I claim is
1st. The casting of the supply pipe b, in one with the upper part of the
carburretting vessel a, substantially as herein described and shown upon the
drawings Fig. 1 & Fig. 2.
2nd. The arrangement of the supply pipe b, having its end 7, stopped, and
provided with holes d, d, underneath, in such a manner as to produce a downward
course for the gas when passing therefrom, for the more complete mixing of the
same with the hydro-carbon vapours.
3rd. The combination of the carburretting vessel, together with the outlet pipe e,
and with one or more pipes f to convey the enriched gas to the illuminating
burners, one or more of such burners being also used to heat the apparatus, as
herein described and shewn upon the drawings.
