Sealed the 23rd May 1865, and dated the 22nd December 1864.
PROVISIONAL SPECIFICATION left by the said Jonathan Grundy Aramı
at the Office of the Commissioners of Patents, with his Petition, on the
22nd December 1864.
I, JONATHAN GRUNDY ARAM, of Bradford, in the County of York, Wheel-
wright, do hereby declare the nature of the said Invention for "AN IMPROVED
MODE OF LIGHTING HOUSEHOLD AND OTHER FIRES," to be as follows:―
My Invention dispenses with the necessity for using chips, paper, and other
materials ordinarily applied for the lighting of household and other fires,
and also effects the desired operation in much less time and at much
less cost.
It consists in the direct application to the coal, coke, or other fuel, of a
lighted jet or jets of inflammable gas (coal gas by preference) to any con-
venient part of the fuel it is desired to ignite. Such jet or jets (when coal gas
is used) may either be applied from gas fittings used for illuminating purposes

page_text: by means of a flexible hose or india-rubber pipe fitted temporarily on to a gas
burner, or a small main for the purpose may be laid from the ordinary gas
main to any house or building to the fuel it is desired to ignite, one or more
jets being attached to an upright springing from such small main, a course I
prefer where a large number of fires are required to be lighted simultaneously.
By this mode I dispense with artificial fuel, save time, and effect the
operation with certainty as well as at much less cost than by the present
system, and I believe this mode of lighting will be of special utility in loco-
motive sheds and large hotels.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Jonathan Grundy Aram in the Great Seal Patent Office on
the 21st June 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JONATHAN
GRUNDY ARAM, of Bradford, in the County of York, Wheelwright, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-second day of December, 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 Jonathan Grundy Aram, Her special licence that I, the said
Jonathan Grundy Aram, my executors, administrators, and assigns, or such
others as I, the said Jonathan Grundy Aram, 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 Inven-
tion for "AN IMPROVED MODE OF LIGHTING HOUSEHOLD AND OTHER FIRES," upon
the condition (amongst others) that I, the said Jonathan Grundy Aram, 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 per-
formed, 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 Jonathan Grundy Aram, do hereby
declare the nature of the said Invention, and in what manner the same

page_text: is to be performed, to be particularly described and ascertained in and by the
following statement thereof, that is to say :-
My Invention dispenses with the necessity (for using chips, paper, and
other materials ordinarily applied for the lighting of household and other
fires, and also effects the desired operation in much less time and at much
less cost.
It consists in the direct application to the coal, coke, or other fuel of a
lighted jet or jets of inflammable gas (coal gas by preference) to any con-
venient part of the fuel it is desired to ignite. Such jet or jets (when coal
gas is used) may either be supplied from gas fittings used for illuminating pur-
poses by means of a flexible hose or india-rubber pipe fitted temporarily on to
a gas burner, or a small main for the purpose may be laid from the ordinary
gas main in any house or building to the fuel it is desired to ignite, one
or more jets being attached to an upright springing from such small main,
a course I prefer where a large number of fires are required to be lighted
simultaneously.
By this mode I dispense with artificial fuel, save time, and effect the
opération with certainty as well as at much less cost than by the present
system, and I believe this mode of lighting will be of special utility in loco-
motive sheds and large hotels.
In order, however, still more to expedite the operation, I use a small fan,
say, of six inches diameter, and of ordinary construction so far as the fan is
concerned, but having an ejection arrangement, which will be better under-
stood by referring to the accompanying Sheet of Drawing.
DESCRIPTION OF DRAWING.
A represents the ejection tube of an ordinary fan B. A small tube a is
fixed in the mouth of the ejection tube through. which the air passes from the
fan. b is a larger tube placed outside the air tube, and in communication
with the gas tube c, which communicates with any gas main in the manner
before named; d is a partial damper open or shut at pleasure, that part of it
which is opposite the air tube being cut away. The inner ends of the two
concentric tubes are united to each other. The fan being put in operation
and gas admitted and lighted the air passes through the centre and the fuel
is ignited. The damper d regulates the current through the outer passage &
by means of handle e. The fan may be held in the hand whilst being used,
the mouth resting upon the fire-bar.
Having now described the nature of my Invention, and in what manner
the same may be performe, I would have it understood that what I claim as

page_text: my Invention is, the principle of lighting fires directly from inflammable
gases substantially by the method described without confining myself to
precise mechanical details of apparatus.
In witness whereof, I, the said Jonathan Grundy Aram, have hereunto
set my hand and seal, this Twentieth day of June, in the year of
our Lord One thousand eight hundred and sixty-five.
JONATHAN GRUNDY ARAM. (L.S.)
