Middlesex, Gas Engineer, for the Invention for "IMPROVEMENTS IN GAS
STOVES FOR HEATING IRONS AND OTHER PURPOSES, AND IN THE CONSTRUCTION
OR IRONS TO BE HEATED AND USED THEREWITH."
Sealed the 31st May 1864, and dated the 3rd December 1863.
PROVISIONAL SPECIFICATION left by the said David Hulett at the
Office of the Commissioners of Patents, with his Petition, on
3rd December 1863.
the
I, DAVID HULETT, of High Holborn, in the County of Middlesex, Gas
"IMPROVE.
Engineer, do hereby declare the nature of the said Invention for
MENTS IN GAS STOVES FOR HEATING IRONS AND OTHER PURPOSES. AND IN THE
CONSTRUCTION OF IRONS TO BE HEATED AND USED THEREWITH," to be as follows:-
My Invention consists, first, in the construction of gas stoves in such manner
that they may have the appearance of an open fire of wood, coal, coke, turf,
or other combustible material, and for this purpose I use terra cotta, fire-clay,
metal, or other suitable material, moulded or shaped to represent wood, coal,
turf, or other combustible material, either solid or hollow by preference
hollow, so that the gas may be introduced into the inside and allowed to ignite
on the surface by means of small holes or apertures. The pieces may be
arranged to suit any ordinary grate or stove, and by the judicious arrangement
of asbestos or other indestructible material attached to such moulded or shaped
pieces, a good representation of an open fire is produced.

page_text: My Invention consists, secondly, in constructing irons to be heated with a
flue or flues in them to allow the heat to be more readily distributed.
My Invention consists, thirdly, in the
the method hereafter described of
economizing the consumption of gas in gas stoves. so that but little gas may
be consumed, except when the stove is required for use. I fit to the supply
pipe a valve or cock made self-acting in the following manner:-On this
valve, or on a lever connected thereto, I place the irons or other articles to be
heated, which, pressing on the valve or its lever, opens the said valve and thus
turns on the gas. On removing the irons or other articles, the weight or
pressure on the valve or its lever is released, and it partially closes as before,
only allowing sufficient gas to pass through to maintain a light until the irons
or other articles are again inserted in the stove.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said David Hulett in the Great Seal Patent Office on the 3rd
June 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, DAVID
HULETT, of High Holborn, in the County of Middlesex, Gas Engineer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Third day of December, in the year of our Lord One
thousand eight hundred and sixty-three, in the twenty-seventh year of Her
reign. did, for Herself. Her heirs and successors. give and grant unto 1
the said David Hulett. Her special licence that I, the said David Hulett, my
executors, administrators, and assigns. or such others as I, the said David
Hulett, 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 STOVES FOR
HEATING IRONS AND OTHER PURPOSES. AND IN THE CONSTRUCTION OF IRONS TO BE
HEATED AND USED THEREWITH," upon the condition (amongst others) that I,
the said David Hulett. my executors or administrators. by an instrument
in writing under my, or their, or one of their hands and seals, should par-
ticularly 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

page_text: 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 David Hulett, 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. reference being had to the Drawings hereunto annexed, that is
to say:-
My Invention consists, first, in the construction of gas stoves in such
manner that they may have the appearance of an open fire of wood, coal,
coke, turf, or other combustible material, and for this purpose I use terra
cotta, fire-clay, metal, or other suitable material moulded or shaped to repre-
sent wood, coal, turf, or other combustible material, either solid or hollow, by
preference hollow, so that the gas may be introduced into the inside and
The
allowed to ignite on the surface by means of small holes or apertures.
pieces may be arranged to suit any ordinary grate or stove, and by the
judicious arrangement of asbestos or other indestructible material attached to
such moulded or shaped pieces, a good representation of an open fire is
produced.
My Invention consists. secondly, in constructing irons to be heated with
a flue or flues in them to allow the heat to be more readily distributed.
Figure of the accompanying Drawings is a longitudinal, and Figure 2 a
horizontal, section of an iron made with flues in the manner just described;
Figure 3 is a vertical section of the same through the line x, y, of Figure 2.
a and b, b, are the flues. The arrows indicate the course of the gas in
its passage through. Although prefer and have shewn three flues. one
ascending and two descending. yet I do not limit myself to this number, but
I have not considered it necessary to shew less or more. as it will be readily
understood by any competent workman that the number of flues, as well as
the direction in which they run. may be varied without departing from my
Invention.
My Invention consists, thirdly. in the method hereafter described of
economizing the consumption of gas in gas stoves, so that but little gas may
be consumed, except when the stove is required for use. I fit to the supply
pipe a valve or cock made self-acting in the following manner: On this valve,
or on a lever connected thereto. I place the irons or other articles to be
heated, which. pressing on the valve or its lever, opens the said valves, and
thus turns on the gas. On removing the irons or other articles, the weight
or pressure on the valve or its lever is released, and it partially closes as before,
only allowing sufficient gas to pass through to maintain a light until the irons

page_text: or other articles are again inserted in the stove. Figure 4 is a view of this
valve constructed as just described and according to my Invention. A is the
valve; B, B, the lever for opening and shutting same: C, the balance weight
on the end of lever. The valve or cock is so arranged that when the iron
kettle or other article to be heated is placed in position for that purpose, its
weight upon the lever depresses it, as shewn by the dotted lines, and so
opening the valve causes the gas to be turned on. Upon removing the article
the balance weight causes the valve to close. The extent of the opening in
the valve or cock can by adjusted by means of a set screw or screws, pins, or
otherwise, so that any given quantity of gas may pass for consumption. In-
stead of the balance weight a spring may be substituted if required. Figure 5
shews the lever attached to a screwed spindle for opening and shutting the
valve. Figure 6 shews a lever attached to a spindle with pin working in a
slot. I do not confine myself to any particular valve or cock, as a similar
arrangement may be attached to almost any kind of cocks or valves.
And having now described the nature of my said Invention, and in what
manner the same is to be performed, I declare that I claim,-
First, the construction of gas stoves so that they may present the appear-
ance of an open fire of wood, coal, coke, turf, or other combustible material,
substantially in manner herein-before described.
Second, the construction of irons for ironing, with a flue or flues in them
for distributing the heat therein, substantially as herein-before described and
illustrated at Figures 1, 2, and 3 of the accompanying Drawings.
Third, the construction and employment of self-acting valves or cocks,
substantially in manner and for the purposes herein-before described and
illustrated at Figures 4, 5, and 6 of the accompanying Drawings.
In witness whereof, I, the said David Hulett, have hereunto set my hand
and seal, this Third day of June, One thousand eight hundred and
sixty-four.
