Year: 1864

page_text: LETTERS PATENT to Richard Pilkington, of West Ham, in the County
of Essex, for the Invention of "AN IMPROVEMENT IN GAS BURNERS."
Sealed the 13th January 1865, and dated the 24th August 1864.
PROVISIONAL SPECIFICATION left by the said Richard Pilkington at
the Office of the Commissioners of Patents, with his Pétition, on the
24th August 1864.-
I, RICHARD PILKINGTON, of West Ham, in the County of Essex, do hereby
declare the nature of the said Invention for "AN IMPROVEMENT IN GAS BORNERS,"
to be as follows (that is to say)
My, Invention has reference to an improvement in gas burners, by which
the illuminating power of the. flame obtained thereby is greatly increased,
economizing and ensuring greater uniformity in the combustion of the gás-than
at present, and consists in constructing or employing, in connection with the
upper part of the burner from which the gas issues, a rectangular wire, staple,
or. arch.arranged, vertically therewith, so as to bisect the lower portion of the
flame longitudinally, and thus, by communicating beat to the less luminous
part thereof, the increase of light is obtained.

WHEREAS Her.most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fourth day of August, in the year of our Lord
One thousand eight hundred and sixty-four, in the twenty-eighth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Richard Pilkington, Her special licence that I, the said Richard
Pilkington, my executors, administrators, and assigns, or such others as I, the
said Richard Pilkington, my executors, administrators, and assigns, should at
time agree with, and no others, from time to time and at all times there-
after 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 "AN IM-
PROVEMENT IN GAS BURNERS," upon the condition (amongst others) that I, the
said Richard Pilkington, my exécutors or administrators, by an instrument in
writing under my, or their, or one of their lands 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 immediately after the
date of the said Letters Patent.
+
NOW KNOW YE, that I, the said Richard Pilkington, do hereby declare
the nature of my said Invention, and in what manner the same is to be per-
formed; to be particularly described and ascertained in and by the following
statement, and the Drawings therein referred to (that is to say):
My Invention has reference to an improvement in gas burners, whereby
greater. uniformity in the combustion of the gas, as also increased brilliancy
of light, is obtained than by the system at present in use, and consists in con-
structing and employing, in connection with the upper portion of the burner
"from which the gas issues," a crown-shaped projecting wire or metallic
staple secured thereto through the medium of vertical slots formed in the
sides of the burner, by which arrangement the said wire is caused to bisect
the lower portion of the flame longitudinally therewith, and admit of being
renewed at pleasure when worn or otherwise rendered useless.
But in order that my said Invention may be more fully understood and
readily carried into effect, I now proceed to describe it by the aid of the
accompanying Drawings, reference being had to the letters and figures thereon
marked (that is to say):
Fig. 1 represents a front elevation of my improved burner; Fig. 2, a side
view thereof; Fig. 3, a top or plan view; Figs. 4, 5; and 6, corresponding
views, showing the crown wire removed, as represented at Figs. 7, 8, and 9 ;
Fig. 10, front elevation of a gas bracket, showing my improved burner applied:

page_text: thereto; Fig. 11, a side view thereof; Figs. 12 and 13, plan views thereof;
and Figs. 14, 15, 16, and 17, a modification of my said improvement as
applied to the bat's-wing burner. In each Figure the same letters of reference
denote similar corresponding parts.
A, A, tubular portion of the burner; B, B, metallic staple or wire crown
fitted thereto; C, C, side slots for securing the same; D, D, socket, into
which the burner is screwed; E, E, ordinary tap; F, F, flame, representing
the fish-tail.
In conclusion to the foregoing description it may be here necessary to note
that drilled holes or cavities formed' in the sides of the burner for the recep-
tion of the crown wire may be employed in lieu of the slots above referred to,
and the re-adjustment or substitution of one wire for another effected as in
like manner through the medium of the slots; and I would further note,
that the form and dimensions of the crown wire may be varied as required,
and composed wholly or partly of metal or otherwise.
Having now fully described the nature of this my said Invention, and the
manner in which the same is to be performed and carried into effect, I would
have it clearly understood that I do not confine myself to the precise details
herein-before set forth and described, as the same might be otherwise varied
without departing from the general principle of this my said Invention, nor
do I claim as of my said Invention the exclusive use of the said combination
or parts thereof, except when the same are employed in and for the purposes
of my said Invention, which I hereby declare to consist in the construction
and employment of the separate parts in connection with the mode of attaching
or securing the crown wire to the burner, in the manner and for the purposes
herein-before set forth and described.
In witness whereof, I, the said Richard Pilkington, have hereunto set
my hand and seal, this Sixteenth day of February, in the year of our
Lord One thousand eight hundred and sixty-five..
