IMPROVEMENTS IN AND RELATING TO GAS-BURNERS
Year: 1884

page_text: COMPLETE SPECIFICATION.
I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co, Patent Agents,
Southampton Buildings in the County of Middlesex do hereby declare the nature
of my invention for "IMPROVEMENTS IN AND RELATING TO GAS-BURNERS" 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 gas burners.
In the use of gas as an illuminating agent, serious and fatal accidents occur from
ignorance as to its proper method of use, for instance by reason of an unskilled or
careless person blowing out the gas flame, instead of extinguishing the flame by
cutting off the supply of gas producing it; further, it often occurs that a sudden
draught of air blows out the gas. In either event unconsumed gas escapes from
the burner, often resulting in injury to the occupant of the roon.
The objects of this invention are to avoid these serious objectious by providing
a gas-burner with novel, simple, and efficient means whereby, if the gas flame be
blown out, the escaping gas will be immediately re-ignited, and by providing novel
devices whereby the gas-flame is prevented from being extinguished and unconsumed
gas escaping from the burner if the flame be exposed to a draught of air. These
objects I accomplish in the manner and by the means hereinafter described.
In the accompanying drawing.
Figure 1 is a vertical central sectional view of a gas burner constructed in
accordance with my invention.
Figure 2 is a similar section on the line x x Figure 1.
Figure 3 is a transverse sectional view taken on the line yy of Figure 1, and
Figures 4 and 5 are detached views of the coil and its carrying sleeve.
1 indicates a gas-burner tube having a burner tip 2 of any suitable forin, and
3 a circular casing having a contracted neck 4 at its base, which casing is secured
to the lower end of the burner and forms an enlarged chamber 5 around the said
burner. The upper part of the casing is provided with a conical cover 6 having
a pendant flange 7 hinged at 8 to the vertical wall of the casing, the said cover
having a slot 9 for the escape of the gas flame. The cover is perforated at 8ª
while the contracted neck 4 of the casing is perforated at 9" for the introduction of,
atmospheric air to the gas flame to ensure a steady light.

page_text: The side of the burner-tube I is provided with a small pipe 10, which com-
municates with the interior of the said burner-tube in such a manner that when
the gas-supply is open to the burner a small jet of the gas will issue from the pipe.
The burner tube is provided at a point above the jet-pipe 10 with a vertically
sliding sleeve 11, carrying a coil 12 of platinum wire, the arrangement being such
that the coil is placed between the upper open end of the jet-pipe 10 and the
burner tip 2. The coil carrying sleeve is divided from end to end as at 13, and
slotted as at 14 in order. to constitute a spring clamp conforming interiorly to the
shape of the burner-tube, so that' in adjusting the sleeve vertically it will be
retained in its adjusted position by frictional contact with the burner-tube incident
to the inherent elasticity of the sleeve and its clamping action on the tube. The
coil may have its ends connected respectively with opposite portions of the divided
sleeve as in Figure 4, or with the sleeve as in Figure 5, and in either event the
device provides simple and efficient means for supporting the coil on. the burner
directly above the jet-pipe 10, and also perinits the coil to be conveniently adjusted
to the best position in relation to the burner tip and jet-pipe, as may be found
most suitable for the objects to be attained.
In practice, when the gas-supply is open and the gas is ignited at the burner and
at the jet-pipe, the flame from the latter, which I designate the secondary flame,
serves to heat the air in the surrounding chamber 5, whereby the flame from the
burner tip is supplied with heated air and its brilliancy thus increased. The
secondary flame also heats the platinum coil 12 to a red heat, and if the main and
secondary flames be extinguished by a violent draft of air the gas escaping from
the jet pipe is immediately re-ignited, by coming in contact with the red-hot coil,
the flame thus produced serving to re-ignite the gas escaping from the burner tip.
These results are ensured by the provision of the chamber which encloses the jet-
pipe, coil and burner, so that the coil is readily brought to a red-heat and at the
same time the gas is mixed in the interior of the chamber with atmospheric air,
which, by contact with the heated coil promptly re-ignites the gas if the same
should be extinguished by any draught.
The burner is useful for street lamps, steam-boats and other places where the
flame is liable to be exposed to draughts of air and it is also of great usefulness in
apartments where the gas flame is likely to be blown out by the ignorance or
carelessness of a person, inasmuch as the gas is immediately re-ignited as stated,
if attempts be made to blow out the flame. The coil may be made of any material
suitable for the purpose, its object being to present a body to the jet-pipe which
will easily be brought to a red-heat and will not be destroyed by exposure to
atmospheric air.
I am aware that heretofore a gas burner has been surrounded by a casing and
provided with a pipe having a platinum wire brush fixed to its upper end in
proximity to the burner tip to aid in the ignition of the gas at the burner; and
also that a gas burner has been provided with a hood over its tip which carries an
interior platinum coil above the tip to re-ignite the gas if the flame be extinguished.
Such, therefore, 1 do not claim, as my invention differs therefrom in having a sleeve
supported on the burner itself between the gas jet-pipe and the burner-tip and
carrying a wire coil between such jet-pipe and burner-tip; also, in having the sleeve
adjustable on the burner between the jet-pipe and the burner tip, and in having
the coil-carrying sleeve in the form of a spring clamp on the burner tube, so that
by its inherent clasticity it will be retained in the position to which it is adjusted.
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 :-
First. The combination of a gas burner tube having a tip, a jet-pipe communi-
cating with the interior of the tube, and a sleeve on the burner tube carrying
a coil between the burner-tip and the open end of the jet-pipe, substantially as

page_text: Second. The combination of a gas-burner-tube having a tip, a jet-pipe com-
municating therewith, and a vertically adjustable sleeve on the burner-tube carrying
a coil between the jet-pipe and the burner tip, substantially as described and for
the purpose set forth.
Third. The combination of a gas burner, a jet-pipe communicating therewith,
a spring clamping sleeve on the burner, and a coil carried by the sleeve, substantially
as described and for the purpose set forth.
Fourth. The combination of a gas-burner, a jet-pipe communicating therewith,
a sleeve divided from end to end and adjustable on the burner, and a coil carried
by the sleeve, substantially as described and for the purpose set forth.
Fifth. A gas-burner consisting of a burner-tube having a tip, a jet-pipe com-
municating therewith, a sleeve on the tube carrying a coil between the open end of
the jet-pipe and the burner-tip, the casing forming the surrounding chamber, and
the conical cover to the casing, substantially as described and as and for the purpose
set forth.
