We HARRY EDWARD ALEXANDER WALLIS of Farringdon Street, London, Gas
Engineer, and HOWARD TAYLOR RATCLIFF of New Summer Street, Birmingham,
Warwick, Brass Founder do hereby declare the nature of the invention to be
as follows:-
The object of this invention is to arrange a conical, bell, or equivalent shaped
canopy on a gas supply pipe that the heat arising from a flame or flames can enter
the hollow and communicate heat to the said pipe and consequently to gas passing
through it for heating the gas to not only improve its illuminating power but to
utilize said heated gas for the vaporization of hydro-carbon previous to the
mixture passing to the burners. The canopy is adjustable by means of screwing,
keys or their equivalents to regulate and determine the height at which said
canopy shall be set within range of the heat arising from the flame or flames and
so determine the amount of vaporization that shall take place for producing
steadiness of flame and maximum of light.
The canopy can be surmounted by rosette or ornamental collar with asbestos or
other nonconductor of heat between so that the canopy can be raised or lowered
by turning the collar which is kept cool for that purpose.

Gas Flame to a Hydro-Carbon Container.
We HARRY EDWARD ALEXANDER WALLIS of Farringdon Street, London, Gas
Engineer, and HOWARD TAYLOR RATCLIFF of New Summer Street, Birmingham,
Warwick, Brass Founder, 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 arrange an adjustable conical bell, or equivalent
shaped canopy on a gas supply pipe having a carburetting vessel in connection that
the heat arising from a flame or flames can enter the hollow of the canopy and
communicate heat to the said pipe and consequently to gas passing through it for
heating the gas, to not only improve its illuminating power, but to utilize said
heated gas for the vapourization of hydro-carbon contained in said vessel previous
to the mixture passing to the burners. The adjustable canopy is set by screwing
to regulate the height within range of the heat arising from the flame or flames
and so determine the amount of vapourization of the hydro-carbon such as
napthaline that shall take place for producing maximum of light and steadiness
of flame, the vessel acting as a governor for that purpose. The canopy is sur-
mounted by or has its upper part provided with a rosette or ornamental collar
with asbestos or other nonconductor of heat between so that the canopy can be
raised and lowered by hand, by turning the collar this being kept cool for that
purpose.
In the annexed drawing A is the bell of conical shape forming the canopy
screwed and adjustable on the pipe B and formed with a hollow C into which
heat from the flames E E can enter and so warm the pipe B and also the gas
passing through it. D is the carburetting vessel connected to the pipe B and the
heated gas as it enters the vessel D conveys its warmth against or upon the
surface of the hydro-carbon (napthaline) placed in said vessel so as to vapourize
said napthaline which vapour commingles or intermixes with the gas and increases
its illuminating power.
The screw thread F on the pipe B may be continued to any required distance so
that the canopy can be brought close to the flame or regulated at any distance
therefrom. The upper part of the canopy is formed with an ornamental collar G
filled with asbestos H to keep it cool and thus enable the canopy to be turned by
hand as required.
The degree of heat that is to be conveyed or communicated by the flame E to
the canopy A and pipe B to determine the amount of vapourization of the hydro-
carbon is as before mentioned regulated by the distance of the canopy therefrom
and by dipping the lower end of the pipe B well into the body of the vessel D
forms a chamber above the level which serves to regulate and steady the flame.
The napthaline can be inserted into the vessel through an aperture otherwise
closed by a tight fitting plug P.

page_text: We are aware that means have been adopted for determining the amount of
heat that shall be communicated to a vapourizing vessel but those refer mainly to
that class of apparatus in which the vessel is at the side of or above the flames.
In the first case the heat imparted to the vessel is by conduction through a metallic
body brought within range of the flame and by the other the heat of the flame
acts directly upon the bottom of the vessel or upon a screen placed between the
flame and the vessel, the heat by this means being also transmitted by conduction
to the vessel and does not act upon the gas before it enters the vessel, but by our
invention there is no conduction of heat to the carburetting vessel except by the
gas which is heated in transit to the carburetting vessel the heated gas first
impinging upon the surface of the hydro-carbon to vapourize it before any heat
is communicated to the vessel consequently the degree of vapourization is
determined by the consumption at the burners.
We
We are aware of a former Patent No. 1331 of the year 1881 in the name of James
Livesey in the specification of which, coal gas is heated while passing through a
swelling forming part of the supply pipe against which swelling heat of a gas flame
impinges but in that case the swelling is immovable. In our Invention we have
no swelling on the gas supply pipe for the purpose but we fit a separate appliance
on the gas supply pipe which we term a canopy. It is hollow and is adjustable on
said pipe by a screwing operation up or down so that the degree of heat imparted to
the inflowing gas can be regulated and the temperature be determined by the amount
of carburation desired.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is
1. The adjustable canopy A on a gas supply pipe B for conveying heat to gas in
transit so that said gas thus heated is caused to impinge upon the hydro-carbon
contained in a vessel for vapourizing said hydro-carbon as herein set forth and as
shown on the annexed drawings.
2. An adjustable canopy on a gas supply pipe provided at its upper part with
asbestos or other nonconductor of heat to facilitate its easy turning by hand for
regulating the distance from the flames of a carburetted gas the consumption of
which is above the vessel as set forth.
