Year: 1883

page_text: PROVISIONAL SPECIFICATION left by the said Sir James Nicholas Douglass
at the Office of the Commissioners of Patents on the 14th June 1883.
Sir JAMES NICHOLAS DOUGLASS of Dulwich in the County of Surrey,
"IMPROVEMENTS IN BURNERS
"
My Invention consists of improvements in burners, and in part improvements
on Letters patent granted to me bearing date January 7th 1881, N° 84.
In the specification of said Letters patent I uso deflectors in combination with
two or more rings of flame.
According to my present invention, said deflectors can be applied to burners of
one ring
In carrying out my Invention, I proceed mainly as follows:-
I take a single ring burner of any approved type (preferably the Argand) and
apply or adapt thereto deflectors as described in my said patent, and with the
application of the glass chimney, the ring of flame is converged-The air and
oxygen acting on the internal and external surfaces of the flame, ensures perfect
combustion, and gives the maximum intensity to the flame.

by the said Sir James Nicholas Douglass in the Great Seal Patent Office on
the 14th December 1883.
Sir JAMES NICHOLAS DOUGLASS, of Dulwich, in the County of Surrey,
"IMPROVEMENTS IN BURNERS
"
My said Invention consists of improvements in the construction of combined-
burners and deflectors as described in the Specification filed at the Office of the
Commissioners of Patents in accordance with one of the conditions contained in
Letters Patent granted to me bearing date the seventh of January One thousand
eight hundred and eighty one and Numbered 84.
The burner which I employ for the purposes of this Invention consists of a
single ring around the exterior of which is arranged an outer deflecting plate the
space between such deflecting plate and the burner being divided by one or more
division rings or partitions. The said deflecting plate is constructed to cover, or
to partially cover, the burner and in connection therewith is a glass chimney
(deflecting or of other known and suitable form) both deflector and chimney being
so formed as to condense the flame to the requisite extent and to deflect the
ascending current of air on to the exterior thereof in such a manner as to invigorate
the combustion of the flame, and augment the intensity of the light.
I will now proceed to refer to the accompanying drawings from which the nature
of my said Invention will be more clearly understood
The same Letters of Reference indicato like parts in both the figures. Figure 1.
is a transverse section of a circular burner A, and a deflector consisting of the
outer deflecting plate B. and one division ring or partition C, and Figure 2. is a
transverse section of a similar burner in combination with a deflector having two
division rings or partitions C. C. The glass chimney D. is in Figure 1., shown
constructed to rest on the upper part of the plate B. and in Figure 2 a shouldered
chimney is illustrated. I do not desire, however, to confine this invention to the
employment of glass chimneys constructed and arranged as shown in the accom-
panying drawings.
Having thus described and ascertained the nature of my said Invention and the
manner in which the same is to be performed I would observe in conclusion that
what I consider novel and original and therefore claim as constituting the Invention
secured to me by the said herein before in part recited Letters Patent, is :-
The combination of burners having one ring for flame with deflectors composed
of an outer deflecting plate B. and one or more interior division rings or plates C.
in connection with a glass chimney (deflecting or of other known and suitable
form) substantially as and for the purposes hercinbefore set forth and described.
In witness whereof I the said Sir James Nicholas Douglass have hereunto set
my hand and seal this thirteenth day of December in the year of our Lord One
thousand eight hundred and eighty three.
