PROVISIONAL SPECIFICATION.
Improved Means of Utilizing the Waste Heat of a Gas Flame for
Warming Purposes Generally and for Increasing the Luminosity
of the Flame.
I, ROBERT ANDREWS GILSON, of 180, Union Street, Southwark, S.E. Stained
Glass Manufacturer, do hereby declare the nature of this invention to be as
follows:-
My Invention has for its object to intercept and store the waste heat passing
upwards from a gas-flame used for lighting purposes and utilizing it for warming the
apartinent generally and at the same time increase the luminosity of the flame.
The heat interceptor and deflector of my invention is placed directly over the
gas flame within a very short distance therefrom so that the flame will burn near to,
or under, but not upon, the surface which is thereby heated to redness or thereabouts.
The heat thus intercepted and stored immediately above the flame is deflected
downwards warming the atmosphere generally and at the same time improving the
luminosity of the flame.
The heat interceptor and deflector may be made of fireclay or other refractory
material or of metal backed with a non-conducting agent such as slag-wool or other
suitable material, to prevent the upward transmission of the heat, and the surface
upon which the gas plays may be of flat, concave, convex or other suitable form.
The contrivance of my invention may be suspended adjustably, so that when
not required for heating it may be raised to a greater distance from the flame
and will then act as an ordinary protector for preventing the blackening of the
ceiling.
The deflector may be so constructed that water or other liquids may be heated or
converted into steam for medicinal or other purposes.

COMPLETE SPECIFICATION.
Improved Means of Utilizing the Waste Heat of a Gas Flame for
Warming Purposes Generally and for Increasing the Luminosity
of the Flame.
I, ROBERT ANDREWS GILSON, of 180, Union Street, Southwark, S.E. Stained
Glass Manufacturer, 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 :-
My Invention has for its object to intercept and deflect the waste heat passing
upwards from a gas-light flame and to utilize it for warming the apartment
generally.
The heat interceptor and deflector of my invention is placed directly over the
gas flame and as near as possible thereto (say about half an inch) so that the flame
will approach closely to, without actually impinging upon, the surface which is
thereby heated to redness or thereabouts. The heat thus intercepted and stored
immediately above the flame assists to ensure the more perfect combustion of the
carbon given off by the flame and also serves to improve the luminosity of the flame
and warm the atmosphere generally.

page_text: One example of the heat interceptor and deflector is illustrated in the accompanying
drawings forming part of this specification.
The heat interceptor and deflector a is, by preference, made of fireclay or other
refractory material. The under surface may be flat, concave, or convex, as may be
preferred, and inay be glazed or enamelled. This heat interceptor is made
preferably from about one to three inches in thickness, although I do not limit
myself in this respect, and it is distinguished from an ordinary smoke consumer by
the fact of its being applied in close proximity to the flame and by its being adapted,
by its mass (which is preferably upwards of two or three. pounds) and by the
nature of the material of which it is made, to intercept and store a large quantity of
heat.
The contrivance of my invention may be suspended adjustably by a wire cord or
chain b So
that when not required for heating it may be raised to a greater distance
from the flaine and will then act as an ordinary protector for preventing the
'blackening of the ceiling.. For this purpose the cord or chain & may be carried over
an overhead pulley, and attached to a counterweight d sliding on the cord or chain.
Or it may be adjustably suspended in any other convenient way.
11.
Having now particularly described and ascertained the nature of the said inven-
ition and in what manner the same is to be performed, I declare that what 1
claim is;
:
...The herein-described heat interceptor and deflector applied immediately above a
gas flame, in the manner and for the purpose specified.
