IMPROVE- MENTS IN GAS BURNERS
Year: 1859

page_text: LETTERS PATENT to John William Kelly, Civil Engineer, of the Town of
Ennis, in the County of Clare, Ireland, for the Invention of "IMPROVE-
MENTS IN GAS BURNERS."
Sealed the 22nd September 1859, and dated the 29th March 1859.
PROVISIONAL SPECIFICATION left by the said John William Kelly at
the Office of the Commissioners of Patents, with his Petition, on the
29th March 1859.
I, JOHN WILLIAM KELLY, Civil Engineer, of the Town of Ennis, in the
County of Clare, Ireland, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN GAS BURNERS," to be as follows, that is to say :-
This Invention consists of, 1st, the application of a small hollow cylinder or
ring to the outside or top of the fish-tail, bat-wing, or other form of burner, by
means of which a more complete combustion of the gas and increase of
illuminating power is obtained.
2nd, by making a number of appertures immediately above or on the
burner side of the cock, which appertures are to be of various sizes, corre-
sponding or nearly so with the sizes of the appertures of the fish-tail or bat-
wing burners from Nos. 0 to 4 (or larger if deemed desirable) at present in
use, and to enclose these appertures in a small chamber, at the top of which
is to be inserted a large fish-tail or other burner. By this means and the aid
of an external index and dial, the key of the cock may be turned so as to
lead the gas through any one of the appertures mentioned, and thus let pass,
to the burner a quantity of gas corresponding exactly to that which would be,
issued by any of the burners now in use.

page_text: The necessity of taking out and putting in different sized burners when
larger or smaller lights are required is thus precluded, and at the same time a
larger degree of combustion and illumination is obtained.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John William Kelly in the Great Seal Patent Office on
the 23rd September 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
WILLIAM KELLY, Civil Engineer, of the Town of Ennis, in the County of
Clare, Ireland, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-ninth day of March, in the year of our Lord
One thousand eight hundred and fifty-nine, in the twenty-third year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said John William Kelly, Her special licence that I, the said John William
Kelly, my executors, administrators, and assigns, or such others as I, the said
John William Kelly, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times thereafter
during the term therein expressed, should and lawfully might make, use,
exercise, and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
GAS BURNERS," upon the condition (amongst others) that I, the said John
William Kelly, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and seals, should
particularly describe and ascertain the nature of the said Invention, and in
what manner the same was to be performed, and cause the same to be filed
in the Great Seal Patent Office within six calendar months next and imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said John William Kelly, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement and the Drawings therein referred to, that is to say :-
My Invention consists of, 1st, the application of a small cylindrical tube or
ring of brass or other metal, to the outside or top of the fish-tail, bat-wing, or
other form of gas jet or burner, by means of which a more complete combustion
of the gas and increase of illuminating power is obtained.
2nd, by making a number of apertures immediately above or on the burner

page_text: side of the cock, which apertures are to be of various sizes, corresponding or
nearly so with the sizes of the apertures of the fish-tail or bat-wing burners
from numbers 0 to 4 (or larger if deemed desirable) at present in use, and to
cover or inclose these apertures in a small bell-shaped or other form of
chamber, at the top of which is to be inserted a fish-tail, bat-wing, Argand, or
other burner of larger apertures or consuming capacity' than any of those
inclosed beneath. By this means, and the aid of an external index or dial,
the key of the cock may be turned so as to lead the gas through any of the
apertures mentioned, and thus let pass to the burner a quantity of gas corre-
sponding exactly to that which would be issued by any one of the burners now
in usc.
The necessity of taking out and putting in different sized burners
when larger or smaller lights are required is thus obviated, and at the same
time a larger degree of combustion and illumination is obtained. For facility
of reference, I shall call this last described burner the "meter burner."
. But in order that these my improvements may be more fully understood
and readily carried into effect, I now proceed to describe them by the aid of
the accompanying Drawings," reference being. had to the Figures marked
thereon, (that is to say):-
=
Figures 1, 2, and 3. represent respectively - an elevation, plan; and longi-
tudinal section of a fish-tail burner, and the manner of applying thereto the
small metallic cylindrical tube or ring. The cylindrical tube is screwed down
upon the burner, and its most efficacious height above the top of the burner
for producing the greatest quantity of light may be adjusted by screwing it
a little higher or lower upon the burner as may be required.
Figures 4, 5, and 6 represent likewise an elevation, plan, and. longitudinal
section of a bat-wing burner, and the manner of applying thereto the metallic
tube or ring. The tube or ring is screwed down upon the bat-wing burner,
and its exact adjustment for producing the greatest light is effected as above
described with regard to the fish-tail burner.
Figures 7, 8, 9, and 10 represent respectively the plan, longitudinal section
and front and side elevations of the "meter burner." Figure 7 is a plan of the
floor of the chamber above the cock, showing the apertures communicating
with the cock. Into these apertures are to be screwed small tubes, with holes
or slits in their tops or sides, corresponding in size to the holes or slits of the
several burners now in use, or to such other size burners as may be deemed
desirable. Thus the three apertures shown in the Drawing are represented
to contain tubes, the holes in which tubes are to be respectively of the gas
issuing capacity of numbers 1, 2, and 3 fish-tail burners, and the number of
such apertures and their tubes, and their respective gas issuing capacities may

page_text: be made greater: or less than shown in the Drawing, as shall be deemed
convenient or desirable. Figure 8 shows the manner in which the bore in
the key of the cock may be made to communicate with any one of the
apertures at pleasure. Figure 9 shows the external dial and index, when the
cock is turned so as that the arrow or other mark upon it coincides with the
number. 1 on the dial; the gas passes through the corresponding aperture; when
the cock is further turned: so as that the arrow points to Number 2 on the dial;
the gas passes through its corresponding aperture, and so on. Figure 10 shows
a side elevation. All the Drawings are upon the full size or natural scale, and
are, it is submitted, explicit and intelligible.
Having now fully described the nature of my said Invention of improvements
in gas burners, and the manner in which the same may be carried into effect; I
would have it understood that I do not intend to confine myself to the precise
details herein-before set forth, as the same might be varied without departing
from the principle of the said improvements; but that which I do claim as my
said Invention, is the construction and application as herein-before described of
a cylindrical tube or ring to the fish-tail, bat-wing, and such like burners,
whereby the illuminating power of the gas consumed is increased, more
particularly of such gas as is not made from, cannel coal.
And also the construction and application of the burner herein-before
described and named the "meter burner," whereby the quantity of gas issued
by any and each of the different sized burners now in use, or that may at any
time be adopted from a number 0 burner to a number 4 burner or higher,
may be exactly obtained and meted out to the one burner, and consumed
with superior advantage.
In witness whereof, I, the said John William Kelly, have hereunto set
my hand and seal, this Thirteenth day of September, in the year
of our Lord One thousand eight hundred and fifty-nine.
Witness,
JOHN ARTHUR MULLINS.
JOHN WILLIAM KELLY. (L.S.)
