PROVISIONAL SPECIFICATION.
Improvements in Gas Burners.
I, SAMUEL HODGER ROBINSON of Fairlight, Streatham Common, in the
County of Surrey, Engineer and Sole Owner of the Wenham Patents, do hereby
declare the nature of this invention to be as follows:-
:-
This invention relates principally to gas burners for lighting, heating, ventilating
and other purposes and has for its object the ensuring of a brilliant white light by
raising the gas to a high temperature before reaching the burner.
According to this invention the method adopted is the use of spiral coils or
tubes of metal or other material in which the supply of gas becomes superheated
by the products of combustion which on passing from the flame come in contact
with the outer surfaces of the coils or tubes before ignition. These coils or tubes
may be of various shapes and placed vertically, horizontally, or otherwise, and may
be adjusted either to upward, downward or other flames.

Improvements in Gas Burners.
1, SAMUEL HODGER ROBINSON, of Fairlight, Streatham Common, in the
County of Surrey, Engineer and Sole Owner of the Wenham Patents, 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 relates to an improvement in gas burners whereby the gas is
heated to a high degree just before it enters into combustion, by which means a
brilliant white light, or a flume having high heating powers is obtained.
The invention consists in the employment of a coiled pipe, through which the
gas is made to pass on its way to the burner nozzle, the said coiled pipe being
heated externally by the hot combustion-gases and the hot air rising from the
flame or flames of the burner, the coil being however sufficiently removed from
the burner nozzle to prevent its coming in direct contact with the flame itself.
Such coiled pipe can be formed and arranged in a great variety of ways,
according to the purpose to which it is to be applied, whether for lamps for
illuminating purposes or for burners for heating, or cooling or ventilating
purposes.
On the accompanying drawings are shewn by way of example some of the
various arrangements and applications of the said pipe coils.
Figure 1 shows a sun-burner gas lamp with my invention applied thereto. To
the gas supply pipe C, closed at c by a partition, is connected the upper end of the
helically coiled pipe A, the lower end of which is connected to the pipe D, leading
to the sun burner B, so that the gas arriving through pipe C is caused to pass
through the coil A on its way to the sun burner, and as the hot combustion gases

page_text: from the latter and the hot air are made to pass in close contact with the outer
surface of the said coil, the gas passing through the same will become highly
heated thereby before issuing from the burner and will thus produce a much
brighter light in burning than the flames of the burners in which the gas supply is
not heated as described.
Figure 2 shews a perspective view of a gas cooking stove, in which the heating
coil A, through which the gas passes on its way to the burner nozzles B B is
arranged as a horizontal flat or zig-zag coil in the upper part of the stove.
Figure 3 shews a vertical section of a heating stove in which the coil A. is
arranged in a vertical flat or zig-zag coil, or it may be a circular or oval coil, over
the single burner nozzle B. Figure 4 shews a similar stove with the circular pipe
coil A arranged horizontally over the row of burner nozzles B.
Figures 5 to 10 shew variously modified forms and arrangements of the pipe
coils.
Figure 5 shews a helical coil A attached at its upper end to a central gas supply
pipe C, and after being coiled helically downwards round the pipe D, the lower
end of which is connected to the burner or burners, it is then coiled upwards again
and communicates at top with the said central pipe D, so that the gas is made to
travel through a considerable length of coiled pipe heated externally by the hot
combustion gases and air rising up from the burner or burners. Figure 6 shews
a similar arrangement to the above, but with only a single coil A, which
communicates with the pipe D at bottom.
Figure 7 shews a flat or zig-zag coil A connected at its upper end to the gas
supply pipe and at its lower end to the burner.
Figures 8 and 9 shew circular coils, arranged respectively in a horizontal and in
an inclined position.
Figure 10 shews a spiral or pyramidal coil, and
Figures 11 and 12 shew respectively a sectional elevation and a plan of a
circular coil of a small height but with the convolutions placed close together,
and connected at top to the supply pipe C and at the bottom to the burner pipe D,
similar to Figure 6.
I do not claim as part of this invention the use of the said coiled gas pipe for
heating the gas supply to a burner, as applied to the "Wenbam" lamp but
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The combination with gas burners for illuminating, cooking, heating or
ventilating purposes, of a coiled pipe through which the gas supply for the
burner or burners is made to pass and which is heated externally by the hot
combustion gases and hot air coming from the flame or flames of the burner so
that the gas issues from the latter in a highly heated condition, substantially as and
for the purposes herein set forth.
2. The several constructions and arrangements of pipe coils for heating the
gas supply to burners herein described with reference to the accompanying
drawings.
