AN IMPROVED CONSTRUCTION OF INVERTED GAS BURNER
Year: 1885

page_text: I, DAVID WILLIAM SUGG of Vincent Works, Vincent Street in the City of
Westminster, Engineer do hereby declare the nature of my invention for AN
IMPROVED CONSTRUCTION OF INVERTED GAS BURNER to be as follows:-
This invention relates to that class of burner in which the flame issues and burns
in a downward direction, the object being to produce a simple and inexpensive
burner which can be readily applied without the assistance of a fitter in case of the
burner in use becoming injured or useless from any cause.
In carrying out my invention I prefer to use steatite, and I take a solid cylinder
of this material of any convenient length and diameter.
One end of this cylinder I turn down to a semispherical form which I will term
the head, and at the opposite end I form a thread by means of which the cylinder
is secured in a suitable hollow holder or the gas pipe.
With a specially formed tool I bore out the cylinder longitudinally and when
near the head I move the tool slightly to one side by which means I form a
chamber in the head of larger diameter than the passage, but corresponding in form
to the external form of the head.
From the outside I form in the semispherical head an annular series of radial
holes extending into the chamber. These holes which may be of any size or
number according to requirements I form in such a manner that the gas shall issue
at an angle of about 45 degrees to the perpendicular.
By the use of my improved construction of burner I avoid all the complication
of parts usually necessary in the so called inverted regenerative burners.

An improved Construction of Inverted Gas Burner.
I, DAVID WILLIAM SUGG, of 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:-
This invention consists in a novel construction of burner or jet to be used with
that class of lamp now known as Inverted Gas lamps, in which the gas is burnt at
the bottom of the lamp, so that the whole illuminating power of the flame may be
utilized, the object of the invention being to obtain better results than heretofore in
the illuminating power, and also to produce a simple and inexpensive burner which
can be readily fitted to the lamp without the assistance of a gas fitter, should a
burner become injured or useless froin any cause.
In the accompanying drawing I have shown my improved burner or jet in
several forms, which will be more particularly referred to.
In carrying out my invention, I prefer to use steatite, of which I take a solid
cylinder of any suitable length and diameter.
One end of this cylinder I turn down to a semi-spherical form, which I term the
head, see a in the sectional views Figs. 1, 2 and 3.-At the opposite end of the
cylinder I form a thread b, by means of which the burner or jet is secured in a
suitable holder, or to the gas pipe.
With a suitably formed tool I bore out the cylinder longitudinally, as shown at c
in Figures 1, 2 and 3, and when inside the head a, I move the tool a little to one
side, by which means I form a chamber a¹ in the head a, of slightly larger diameter
than the passage c, but corresponding in form to the external form of the head a.
From the outside I pierce, in the semi spherical head a, an annular series of
radial holes a², extending into the chamber a¹. These holes a³ I so arrange that
the gas will issue at an angle of about 45 degrees to the perpendicular.
The number and size of the holes will vary according to requirements; thus for
a burner to burn 2 cubic feet per hour, and with holes of 003 of an inch, I have
found eleven holes to give the best results, while for a 6ft burner with holes
005 of an inch, I find fourteen holes the most suitable number. It is however
impossible to give any strict rule, except that if the separate jets of gas are
distinguishable, that is to say, do not form a complete ring, or saucer-like flame,
the number of holes is not sufficient. The maximum number of holes can only be
determined by making several burners with a different number of holes of a given
.size, and testing the illuminating power with the photometer.
By forming the holes in the side of the head, I retain a solid portion at the
bottom of the gas tube, which acts, so to speak, as a baffle, which prevents the
stream of gas issuing with a rush, and causes the gas to collect and settle down in
the chamber a¹, from which it flows through the holes quietly in equal streams.
Although, for general purposes, a single ring of holes is sufficient, I may, in some
cases, prefer to have a double ring of holes, in which case the holes of the second
ring are arranged between the holes of the first ring, as shown in the plan view

page_text: Fig. 4, and in this way I obtain a thicker flame, which is sometimes desirable.
The number of the holes of a given size will be regulated as before explained.
I have sometimes found that in these burners, after they have been alight some-
time, a deposit of carbon will be formed at the bottom below the holes.
This carbon deposit seldom forms in the centre of the burner, in which position
it might be of service, but most often on one side or the other, the consequence
being that the flame is drawn down on that side, and the shape is spoilt. In order,
however, to prevent the formation of the carbon, and at the same time retain any
advantage that such a deposit, if in the proper place, might have, I form on the
under side of the burner, and centrally thereof, a small pip d, which may be of the
dovetail form shown at Fig. 2, or of the conical form shown at Fig. 3, and in the
plan view Fig. 5.-This pip & draws down the flame equally all round, forming a
more saucer-like flame than, without it, is possible, becomes incandescent by the
beat, and serves to destroy, or rather causes the perfect combustion of, any particles
of carbon that may deposit temporarily upon it.
By forming the chamber a¹, as described, in the head, I thin down the walls
thereof, so that when I pierce the holes, each hole is distinct and separate inside as
well as out, and I am therefore enabled to get a more equable supply of gas than I
should, were the holes to run into one another internally.
By the use of my improved construction of burner, I avoid all the complication
of parts usually necessary in the so-called inverted regenerative burners.
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. An inverted gas burner constructed as herein shown and described.
2. In an inverted gas burner, the combination of a chamber, as a¹ in the head a
of the burner, with holes as a², said holes being pierced in the side walls of such
chamber, as and for the purpose set forth.
3. In an inverted gas burner, the combination with a hollow head, as a a¹,
having holes a in the sides thereof, of a pip or projection, as d, as and for the
purpose set forth.
