the Supply of Gas thereto.
I DAVID WILLIAM SUGG of Strathsteven, Ouseley Road, Balham in the County of
Surrey, Engineer do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in the burner for which I have obtained
Letters Patent dated the 3rd day of February 1885 No. 1499.
In large burners constructed according to the said patent, I have found that the
separate jets of gas issuing from the holes in the steatite burner, do not properly
combine to form a perfect sheet of flame and also that the flow of the gas is not always
evenly distributed, both of which disadvantages more or less impair the efficiency of
the burner.
Now the object of this invention is to overcome these disadvantages, and the
invention consists first in so forming the holes in the burner as to ensure the separate
jets, so to speak, impinging on one another and thereby forming a perfect sheet of
flame, and second, in providing means inside the burner whereby the supply of gas
shall be introduced to the burner so as to be evenly distributed on all sides.
In carrying out my invention I form the burner with a hollow head, as described
in the former patent, but instead of piercing the holes radially with a slight
downward inclination, as therein described, I form them tangentially with the
downward inclination.
The means for distributing the gas consists of a short tube formed at its upper end
with a flange. This tube is inserted in the burner with the flange resting on the
top, and its length is such that it will extend below the holes and nearly to the bottom
of the burner. Thus the supply of gas will be conveyed centrally to the bottom of
the burner and will be evenly distributed to the holes.
.
It will be evident that this distributing tube may be applied to the burners as
described in the patent before mentioned.
Dated this 15th day of December 1886.

the Supply of Gas thereto.
1 DAVID WILLIAM SUGG of Strathsteven, Ouseley Road, Balham, in the County of
Surrey, 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 :-
This invention relates to improvements in the burners for inverted lamps for which
I have obtained Letters Patent dated the 3rd day of February 1885, No. 1499.
The inverted lamps to which these improved inverted burners are particularly
intended to apply, are those constructed in accordance with, or having the same
characteristics as the lamp for which a patent was granted to me and dated the
21st of February 1884 No. 3707; but with a slight modification, the new burner is
also applicable for use in those lamps of the same class in which the burner is placed
low down in the glass.
In some of the burners constructed according to my said former patent, I have
found that the separate jets of gas issuing from the holes in the burner, do not
properly combine to form a perfect sheet of flame, and also, that the flow of the gas
is not always evenly distributed, but sometimes inclines more to one side than the
other, giving an irregularly shaped flame, which smokes on the side where the excess
of gas issues, and thus rapidly impairs the ventilation of the now well known inverted
lamps by the deposition of carbon.
Now the object of this invention is to overcome these disadvantages, and the
invention consists, first, in so forming the holes in the burner, as to ensure the
separate jets properly combining, and thereby forming a perfect sheet of flame; and
second, in providing means inside the burner, whereby the supply of gas shall be so
introduced to the burner as to be evenly distributed on all sides.
In carrying out my invention, I form the burner with a hollow head, as described
in the specification of the former patent, but instead of piercing the holes radially
with a slight downward inclination as therein described, I form them tangentially to
an imaginary concentric circle within the burner, giving them either an upward or
downward inclination, according to the form of lamp in which the burner is to be
used. For example, in the lamp for which I have obtained a patent before referred
to, I use the holes with a downward inclination, but in the lamp in which the burner
is placed low down in the glass, I use the holes with the upward inclination.
The means for distributing the gas consists of a short tube formed at its upper end
with a flange. This tube is inserted in the burner with the flange resting on the top,
and its length is such that it will extend below the holes, and nearly to the bottom
of the burner. Thus, the supply of gas will be conveyed centrally to the bottom of
the burner, and will be evenly distributed to the holes.

page_text: It will be evident that this distributing tube may be applied to the burner
described in the patent before mentioned.
In the accompanying drawing, Fig. 1 shows my improved burner in side elevation,
Fig. 2 in sectional elevation, and Fig. 3 in cross section, on the line of the holes. All
the figures are on an enlarged scale, to more clearly show the invention.
A is the hollow head of the burner, the walls of which are thinned down, so that
each of the holes will be distinct and separate, as described in my former patent.
The holes, as will be seen by the cross section Fig. 3, are formed tangential, or nearly
so, to the inner periphery of the gas distributing pipe before mentioned. By this
means, a spiral movement in the several jets will be produced, and as the form of the
exit will be slightly oval, a flattened form will given to each jet of gas.
The currents of air coming down directly on to the flame, and at an angle to the
jets, cause a change in the direction of the jets, and serve to spread them out, thus
producing a perfect sheet of flame.
The number of the holes will depend upon the size of the same, and can only be
ascertained by experiment in the manner described in my former patent.
B is the distributor or regulator tube. This tube, it will be seen, is formed with a
flange B¹, and extends downwards nearly to the bottom of the hollow head, A, of the
burner, and some distance below the row of holes. By thus carrying the gas centrally
of the burner, and below the holes, I ensure that the gas shall be evenly distributed
to the latter, and thus I obtain a regular and even flame.
In Fig. I have shown the distributor tube applied to a burner of the form shown
in my former patent.
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 :-
1. A hollow headed inverted burner having holes pierced in the head tangentially
to an imaginary circle within the burner and concentric therewith, and with a slight
downward or upward inclination, as and the purposes set forth.
2. The application to hollow headed inverted burners, of a distributor or regulator
tube, as and for the purpose set forth.
