page_text: I HARRY EDWARD ALEXANDER WALLIS of Farringdon Street, London, Gas
Engineer, do hereby declare the nature of this invention to be as follows:-
The object of this invention is, to construct and arrange a cup or conical shaped
conductor of heat, over or partially over a gas flame so that the heat vapour arising
from it, may be gathered within the hollow for imparting the maximum of heat
thereto before escaping.
The conduction is part of or connected to a vessel containing a bydro-carbon
preferably of a solid character, for reducing it to liquid and for vapourizing it
previous to its admixture with, or while in combination with coal gas in order to
increase the lighting power of same. The cup or conical shaped heat receiver and
conductor may be plain, fluted or of other construction, but of a solid-not
hollow form for direct conduction of beat by metallic conduction, there being no
chamber in which air, gas or vapour is acted upon by the heat taken up by the
conductor proper and then conveyed into the carburetting vessel.

Engineer, 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 :-
=;
The object of this invention is to construct and arrange a cup or conical shaped
conductor A of heat over or partially over a gas flame so that the heat vapour
arising from it may be gathered within the hollow for imparting, the maximum of
heat thereto before escaping.
The conductor B is part of or connected to a vessel C containing a Hydro carbon
preferably of a solid character for reducing it to liquid and for vapourizing it
previous to its admixture with, or while in combination with coal gas in order to
increase the lighting power of same. The cup or conical shaped heat receiver A
and conductor B may be plain, fluted or of other construction but of a solid―not
hollow form for direct conduction of heat by metallic conduction there being no
chamber in which air, gas, or vapour is acted upon by the heat taken up by the
conductor proper A and then conveyed into the carburetting vessel C.
Figure 1 of the annexed drawings shows an arrangement of the apparatus for
one gas flame, the coal gas enters by the tube D' and is admitted by the two way
cock E to either of the pipes F, G, the. pipe F. supplying the flame with nearly pure
gas, while the pipe G supplies the gas to be mixed with the Hydro-carbon vapour
in the vessel C.
Figure 2 shows the invention adapted to two lights, but any number may be
employed as desired.
I am aware that Hydro carbon bodies (notably napthaline) have been employed
for carburetting coal gas for the purpose of enriching the flame thereof the
application and use of such material for that purpose having been described in the
Specifications of Letters Patent granted to Donovan and to Bowditch in the years
1830 and 1862 respectively and also by others since those years therefore my
invention does not relate to the application or use of a Hydro-carbon (Napthaline)
as a means of enriching gas flame in a broad sense but to special appliances or
special means by which the use of Hydro-carbon (Napthaline) is enhanced without
detriment to the apparatus employed.

page_text: 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
Affixing to a Hydro-carbon container a solid conductor of heat, one end of said
conductor being of cup or conical form and fitted over a gas flame and the other in
the body of the carburetting vessel below the surface of the Hydro-carbon for
heating and vaporizing the same previous to admixture with the inflowing gas for
the purpose of enriching said gas as described and as shown in the annexed
drawings.
