PROVISIONAL SPECIFICATION.
Improvements in Incandescent Gas Burners.
I DAVID WILLIAM SUGG of 79 Queen Victoria Street, London, E.C., and
Vincent Works, Vincent Street in the City of Westminster, Engineer, do hereby
declare the nature of this invention to be as follows:-
The object of this invention is to overcome the difficulties hitherto inherent in
incandescent gas lighting, namely, the deposition of carbon on the mantle and
other parts, the fracture of the mantle at the neck, and the liability of the glass
chimney to crack, and to produce, in addition, an automatic cut off in combination
with a pilot light, whereby the use of special taps or cocks for the burner and the
pilot light, when a pilot light is employed, are dispensed with.
The deposition of the carbon may be said to arise principally from the want of
oxygen to the centre of the flame, and the fracture of the mantle and the cracking
of the glass are practically caused by the lack of a proper exit at the top of the
mantle for the products of combustion, which are thus deflected outwards through
the upper part of the mantle onto the chimney, thus cracking the chimney and
destroying the mantle.
In carrying out my invention, I employ a disc or diaphragm valve, which rests
on a raised seat contained in a suitable chamber in a casing provided with a
threaded socket for attachment to the chandlier arm or other fitting.
In the casing I form a side gas way from the valve chamber below the valve to
a central hollow peg above the chamber, and I also form a relief air passage from
the top of the chamber to the outside of the casing, near the central peg, to relieve
the pressure on the top of the valve.
From a point in the threaded socket below the valve seat, I carry up to the top-
of the burner a small tube for the pilot light.
The gas issues from the central peg into a mixing chamber, which is provided
with suitable lateral openings for air, as is usual in burners of the Bunsen type,.
and this mixing chamber terminates in an annular burner of the Argand type,
through the lower part of which air tubes are inserted (preferably radial), so that
air may pass to the centre of the burner.
This central space is fitted with a plug in which a central rod or peg is inserted,
and this rod carries at its upper end a perforated supporting disc for the mantle,
preferably of woven or sheet asbestos steeped in a suitable fireproof solution, and
having perforations of such a size that the products of combustion will readily
pass out, instead of being deflected through the mantle onto the glass.
The central column of air serves to support combustion, and thus to use up, so
to speak, the carbon atoms, which might otherwise be deposited on the mantle and
other parts.
By the use of the improved burner, the mantles will last longer than heretofore,.
as they do not break away at the upper part, being uniformly supported all round
at the neck.
The cock or tap on the arm of chandelier, or the bracket, is provided with an
additional but removable stop pin, by which means the complete shutting off of
the gas is prevented, when the pilot light is required. The pressure of the gas
thus supplied will not be sufficient to raise the automatic cut off, and only enough.
gas will be supplied to keep the pilot alight.

page_text: Improvements in Incandescent Gas Burners.
I DAVID WILLIAM SUGG of 79 Queen Victoria Street, London, E.C., and
Vincent Works, Vincent Street in the City of Westminster, 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 overcome the difficulties hitherto inherent in
incandescent gas lighting, namely, (1) the deposition of carbon on the mantle and
other parts; (2) the fracture of the mantle at the neck; and (3) the liability of
the glass chimney to crack; and to produce, in addition, an automatic cut off in
combination with a pilot light, whereby the use of special taps or cocks for the
burner and the pilot light when a pilot light is employed are dispensed with.
The deposition of the carbon may be said to arise principally from the want of
oxygen to the centre of the flame, and the fracture of the mantle and the cracking
of the glass are practically caused by the lack of a proper exit at the top of the
mantle for the products of combustion, which are thus deflected outwards, through
the upper part of the mantle, onto the chimney, thus cracking the chimney and
destroying the mantle.
And in order that my invention may be clearly understood, I will proceed to
fully describe it, reference being had to the accompanying drawing, which
shows, in sectional elevation, (at Fig. 1) a burner constructed according to my
invention.
In carrying out my invention, I employ a disc or diaphragm valve A, which
rests on a raised seat B, contained in a suitable chamber B₁ in a casing B*
provided with a threaded socket B³, for attachment to the chandelier arm or other
fitting.
In the casing B2, I form a side gas-way C, from the valve chamber B', below
the valve A, to a central hollow peg or stump D above the chamber B', and I also
form a relief air passage D' from the top of the chamber B' to the outside of
the casing, near the central stump D, to relieve the pressure on the top of the
valve A.
From a point in the threaded socket B, below the valve seat B, I carry up to
the top of the burner a small tube E for the pilot light.
The gas issues from the central stump D into a mixing chamber F, which is
provided with suitable lateral openings F¹ for air, as is usual 'in burners of the
Bunsen type, and also a guard'F', which extends downwards beyond the openings F¹.
This mixing chamber F. terminates in an annular burner G, of the Argand type,
through the lower part of which air tubes H are inserted (preferably radial), so
that air may pass to the centre of the burner G.
In the central space is fitted a plug G', in which is inserted a central rod or
or peg J, and this rod carries at its upper end a perforated supporting disc K for
the mantle. It will be obvious that any other form of Bunsen burner. may be
employed which will permit of a central air supply and a plug for the central rod J.
The suporting disc K may be of any suitable material, but is preferably of woven
or sheet asbestos, steeped in a suitable fireproof solution, and having perforations
(see the detail view, Fig. 2) of such a size that the products of combustion will
readily pass out, instead of being deflected through the mantle onto the glass
chimney.
The central column of air serves to support .combustion, and thus to use up, so
to speak, the carbon atoms which might otherwise be deposited on the top of the
mantle and other parts.

page_text: By the use of the improved burner, the mantles will last longer than heretofore,.
as they do not break away at the upper part, being uniformly supported all round
at the neck, and the degree of incandescence will be considerably increased.
The cock or tap on the arm of chandelier or the bracket, is provided with an
additional, but removable stop pin, by which means the complete shutting off of
the gas in one direction is prevented when the pilot light is required. The pressure
of the gas thus supplied to the pilot light E will not be sufficient to raise the
automatic cut off, and only enough gas will be supplied to keep the pilot alight.
The burner will carry the usual gallery for the glass chimney, and may, if
desired, be provided with a governor or regulator. L is a regulating screw, the
use of which is now well known. The valve A may be of any form or material,
but I prefer to use a valve consisting of two discs of thin metal or other material,
connected together at a suitable distance apart by a stem. This double valve has
two seats, one below at B, as before stated, at the inlet for the gas, and the
other B above the valve A. The object of the upper seat B is to prevent gas.
passing out by the air opening D₁, when the valve is raised by the pressure of the
gas below it.
'
Having now particularly described and ascertained the nature of the said inven--
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. An incandescent gas lamp burner constructed, arranged, and operating as.
herein shown and described.
2. In an incandescent gas lamp burner, providing for a central current of air, as
and for the purposes set forth.
3. In an incandescent gas lamp burner, the use of an automatic cut-off valve in
combination with a pilot light, as set forth.
4. The automatic cut-off valve arrangement for incandescent gas lamp burners,.
as herein shown and described.
Dated this 3rd day of January 1896.
