PROVISIONAL SPECIFICATION left by the said William Robert Lake at the
Office of the Commissioners of Patents on the 26th August 1882.

nication to him from abroad by Eugénie Zoé Ingé Téterger, of Paris, France.]
This invention relates to an improved gas-burner which spreads the gas in a
thin sheet in the form of a ring or halo around the circumference of the burner.
The said burner may be constructed in various manners, of which those hereinafter
described are examples.
According to the said invention I provide a hollow rod or tube of any suitable
form, the upper end of this tube is closed with the exception of a number of small
holes bored or otherwise made in it laterally, through which the gas passes into an
annular space enclosed by a cup below, and a disc above, the latter being held in
the centre by a screw. The said cup forms a part of, or is attached to, the said
tube. Between the cup and the disc is left a very narrow passage all round, by
which the gas is spread out in a thin sheet in such a manner that it burns in the
form of a halo or ring.
As the thickness of the sheet of gas which flows from the burner is very slight
the consumption of gas is very small, moreover the ring of gas is on all sides in
contact with the external atmosphere so that the combustion is complete and all
the illuminating power of the gas is utilized.
Another form of the said improved gas-burner is made with three slits or
apertures upon its circumference, separated by three small plates or pieces which
connect the lower part of the burner with a cap or upper part. These slits or
apertures, which are of equal size, allow the gas to escape so that it will burn in

page_text: the form of a ring or halo. But in this arrangement the said plates or pieces form
slits or divisions in the flame; to avoid this inconvenience I provide two circles of
slits or apertures, one above the other, so that the said plates or pieces in one circle
are midway between those in the other. By this means there is no interruption in
the flame.
According to another modification I provide the burner with an annular piece
perforated with a number of holes, or series of holes, through which the gas
escapes.
In order to prevent the flame from rising or from disturbance by currents of air
from below, I sometimes fix a circular plate of glass below the burner, or upon the
tube below that part from which the gas issues.
When it is desired to arrange this burner in combination with an ordinary
burner, the latter is placed above, and is supplied by means of, a small central tube.
These burners may be made of any suitable form and size to accommodate them
to domestic or industrial use and according to the kind of lighting required.

nication to me from abroad by Eugénie Zoé Ingé Téterger, of Paris, France
This invention relates to an improved gas-burner from which the gas issues in a
thin sheet in the form of a ring or halo around the circumference of the burner.
The said burner may be constructed in different forms or modifications, some of
which are illustrated in the accompanying drawing.
One form of the improved gas burner is shewn in elevation in Figure 1, in plan
in Figure 2, in vertical section in Figure 3, and in horizontal section in Figure 4.
A represents a hollow rod or stem which may be of any suitable form, the upper
end of this tube is closed with the exception of a number of small holes a bored or
otherwise made in it laterally, through which the gas passes into an annular
enclosed by a cup b below and a disc c above, the latter being held in the centre
by a screw d. Between the circumference of the cup b and the disc c is left a very
narrow passage through which the gas is spread out in a thin sheet in such a
manner that it burns in the form of a halo or ring, as shown in Figures, 1 and 2.
space
As a very thin sheet of gas flows from the burner, the consumption of gas is
very small, moreover the ring of gas is on all sides in contact with the external
atmosphere so that the combustion is complete and all the illuminating power of
the
gas is utilized.
Figures. 5 is a side elevation and Figure 6 a horizontal section on the line x, x
Figure. 5, of another form of the improved gas-burner in which there are three
horizontal circumferential slits or apertures e separated by small projections or
pieces f which connect the lower part B of the burner with the cap or upper part C.
These slits or apertures e, which are of equal size, allow the gas to escape so that it
will burn in the form of a ring or halo. But in this arrangement the projections
or pieces f form slits or divisions in the flame; to obviate this defect, I sometimes
provide two series of slits or apertures e, one above the other as shown in Figures 7,
8 and 9 so that the projections or pieces f in one series are midway between those
in the other series. By this means there is no interruption in the flame.
Figures 10 and 11 show another form or modification of the burner in which I
employ an annular piece perforated as shown with a number of holes through
which the gas escapes.
Figure 12 illustrates one of the improved gas burners fitted to a lamp.
In order to prevent the flame from rising or from disturbance by currents of air
from below, I sometimes fix a glass cup v below the burner. I provide a reflector R,
and make the lamp with double walls within which circulates the air from the
exterior for supplying the flame.
When it is desired to arrange the improved burner in combination with an
ordinary burner, the latter is placed above, as at x¹ Figure. 7, or at one side as at y
Figure. 12, and is supplied by means of a small tube t.
These burners may be made of any suitable form and size to accommodate them
to domestic or industrial use, according to the kind of lighting required.
Having thus fully described the said invention as communicated to me by my

page_text: foreign correspondent and the manner of performing the same, I wish it understood
that I claim :-
The improved gas-burner constructed as above described so that the gas will
issue therefrom in a thin sheet in the form of a ring or halo, substantially as set
forth.
In witness whereof I the said William Robert Lake have hereunto set my
hand and seal this twenty third day of February in the year of our Lord
one thousand eight hundred and eighty three.
