Improvements in Burners for Incandescence Gas Lights.
We, ALEXANDER MACDONALD, of Springbank, Brodick, Arran, in the
County of Bute, North Britain, Gentleman, and ALEXANDER PATERSON,
of 158, Woodlands Road, in the County of Glasgow, North Britain, Engineer,
do hereby declare the nature of this invention to be as follows, that is
to say-
Our said invention has for its objects to improve incandescence gas lights, to
obtain a more complete and uniform incandescence of the mantles, to prevent the
mantles from being injured by fluctuations of air or gas currents, the mantles
being thus rendered more durable, and to allow of the satisfactory use of rich gas
such as is obtained from oil without smoking or depositing carbon, the improved
burners being with suitable adjustments advantageously applicable with combustible
gases of various qualities, and very economical in the quantity of gas used for a
given illuminating effect.
Our improved appliances may be fitted to incandescence burners constructed as
hitherto, or the construction may be altered so as to embody our improvements.
Our invention consists in providing the burner with means for adjusting the
admission of air at two parts. As in existing burners of the kind air is admitted
at the lower part of the burner tube to mix with the combustible gas prior to its
ignition. We make this primary admission adjustable by fitting a movable piece
so as to close the air inlet holes more or less. In combination with the adjustable
primary admission of air, we make the admission of air at the base of the chimney
adjustable also. In ordinary incandescence burners a comparatively large admission
of air takes place through openings in the chimney gallery these openings being
permanent; and the consequent passage of too much cold air up the chimney
and on the outside of the mantle, prevents complete combustion and incandescence
and lowers the temperature and diminishes the illuminating effect. The proportions
of air to be admitted primarily and secondarily so as to obtain the best effects,
depend on the quality and also on the pressure of the combustible gas employed,
and are easily determined by a few trials with different adjustments of the air,
inlets. In the case of existing burners or of ordinary construction there may be
fixed at the bottom of the chimney gallery a flat or conical plate made with,
suitable perforations and in contact with this plate there may be arranged a
movable plate having perforations and made adjustable so as to open or close
the openings more or less. Or beneath the chimney gallery there may be a
tube or a shell of any ornamental form with air inlet holes made in it and provided
with a movable piece adapted to cover the holes more or less.

We, ALEXANDER MACDONALD, of Springbank, Brodick, Arran, in the
County of Bute, North Britain, Gentleman, and ALEXANDER PATERSON,
of 158, Woodlands Road, in the County of Glasgow, North Britain, 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, that is to say:-
Our said invention has for its objects, to improve incandescence gas lights,
to obtain a more complete and uniform incandescence of the mantles, to prevent
the mantles from being injured by fluctuations of air or gas currents, the mantles
being thus rendered more durable, and to allow of the satisfactory use of rich
gas such as is obtained from oil without smoking or depositing carbon, the
improved burners being with suitable adjustments advantageously applicable with
combustible gases of various qualities, and very economical in the quantity of gas
used for a given illuminating effect. The objects of the invention are effected
by the provision of means for controlling the admission of air to the space between
the exterior of the mantle and the chimney, combined with means for controlling
the air admission to the interior of the burner tube.
And in order that our said invention and the manner of performing the same
may be properly understood we hereunto append a sheet of explanatory drawings to
be hereinafter referred to, and showing parts of burners for incandescence gas
lights, as made according to our invention.
Figures, 1, and 2, of the drawings are respectively a plan and a vertical section of
one modification of the improved burner.
Figures, 3, and 4, are respectively an elevation and a vertical section of separate
modifications of a detail of the improved burner, the modification shown in Figure, 3,
being the same as that.shown in Figures, 1, and 2.
In these drawings the same reference letters are used to mark the same or like
parts wherever they are repeated.
Our improved appliances may be fitted to incandescense burners constructed as
hitherto, or the construction may be altered so as to embody our improvements.
Our invention consists in providing the burner with means for adjusting the
admission of air at two parts. As in existing burners of the kind air is admitted
at the lower part of the burner tube, A, to mix with the combustible gas prior to
its ignition. We make this primary admission adjustable in a usual manner by
fitting a movable piece, B, so as to close the air inlet holes, C, more or less. In
combination with the adjustable primary admission of air, we make the admission
of air at the base of the chimney (not shown) adjustable also. In ordinary incan-
descence burners a comparatively large admission of air takes place through)
openings, D, in the chimney gallery, E, these openings being permanent, and the
consequent passage of too much cold air up the chimney and on the outside of the "
mantle (not shown) prevents complete combustion and incandescence, and lowers
the temperature and diminishes the illuminating effect. The proportions of air to.
be admitted primarily and secondarily so as to obtain the best effects, depend on
the quality and also on the pressure of the combustible gas employed, and are
easily determined by a few trials with different adjustments of the air inlets. In
the case of existing burners or of ordinary construction we fix at the bottom of the
chimney gallery, E, a plate, G, which may be conical as shown in Figures, 1, 2,
and 3, or cylindrical as shown in Figure, 4, or flat, and is made with suitable
perforations, H. In contact with the plate, G, tbere is arranged a plate, J, made
with perforations, K, and movable by an arm, L, so as to open or close the

page_text: openings, H, more or less. Or beneath the chimney gallery, E, there might be a
tube or shell (not shown) of any ornamental form with air inlet holes in it and
provided with a movable piece to cover the holes more or less.
The outer plate, J, is held in contact with the inner conical plate, G, by a
piece, M, and the arm, L, which are both in one with the outer plate, and which
after projecting through the inner plate, are suitably bent for the purpose. The
conical plate, G, is made with an upper tubular part, N, and a lower flanged
part, P; and in fitting the plate, G, to the burner, the usual neck ring Q, is first.
removed, and the plate is thereafter slipped over the neck, R, until notches, S, in
the flanged part, P, engage with projections, T, on the bottom part of the chimney
gallery, E, the neck ring being then replaced to hold the appliance between it and
the lower part of the gallery. The engagement of the notches, S, in the flanged
part, P, of the inner plate, G, with the projections, T, of the gallery, E, prevent
the inner plate from turning with the outer plate, J, when the latter is being
adjusted assuming the gallery to be held at the same time if necessary.
The cylindrical plate, G, Figure, 4, is also made with a lower flanged part, P,.
having similar notches, S, in it engaging with similar projections (T) on the
gallery (E), and the outer cylindrical plate, J, is held in contact with the inner
plate by a separate upper tubular piece, N, and the neck ring, (Q) the latter of
which holds the whole appliance on the burner neck (R) between it and the
gallery.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
In a burner for an incandescence gas light, providing separate inlets for air into
the burner tube and into the space between the upper part of the burner tube and
the chimney, respectively, the said inlets being fitted with adjustable appliances
for separately regulating the air admission at the two parts, substantially as.
hereinbefore described.
