AN IMPROVED FUEL ECONOMIZER AND HEATING OR STOVING APPARATUS
Year: 1873

page_text: LETTERS PATENT to William Fawcett, of Burton Salmon, in the
•
County of York, Gentleman, for the Invention of "AN IMPROVED
FUEL ECONOMIZER AND HEATING OR STOVING APPARATUS."
PROVISIONAL SPECIFICATION left by the said William Fawcett at
the Office of the Commissioners of Patents, with his Petition, on
the 3rd March 1878.
I, WILLIAM FAWOETT, of Burton Salmon, in the County of York,
5 Gentleman, do hereby declare the nature of the said Invention for "An
IMPROVED FUEL ECONOMIZER AND HEATING OR STOVING APPARATUS," to be as
follows:-
My Invention is applicable to fire-grates or stoves of ordinary con-
struction used in dwelling houses and other places, and has for its object
the utilization of a great portion of the waste heat which would otherwise
pass off unemployed up the chimney or flue, by employing it for heating
or "stoving" in rooms or other places, and is as hereafter described. I
pass one or more tubes or pipes of fire-clay or metal into or through the

page_text: fire and as far as may be required below it, so as to prevent any smoke
passing into the interior thereof. The pipes or tubes passing from the
fire may be laid in any direction, and conducted into any room or out-
house, and there coiled or passed round as required. The tubes or pipes
are left open at both ends to allow free passage of atmospheric air. !
Those parts of the tubes exposed to the fire become intensely hot, the
atmospheric air is readily admitted into the tubes, and brought to a high
degree of temperature on passing through the heated parts. A current
of air is by this means created, the cold air entering the tubes at the
lower ends, and passing along and out in a heated state at the other end
or ends. Any required number of tubes may be employed.
By the herein-before described arrangement of tubes rooms and other
places may be heated or stoved without additional fires, saving thereby a
SPECIFICATION in pursuance of the conditions of the Letters Patent, 1
filed by the said William Fawcett in the Great Seal Patent Office
on the 3rd September 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
FAWCETT, of Burton Salmon, in the County of York, Gentleman, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Third day of March, in the year of our Lord
One thousand eight hundred and seventy-three, in the thirty-sixth year
of Her reign, did, for Herself, Her heirs and successors, give and grant
unto me,
the said William Fawcett, Her special licence that I, the said 2
William Fawcett, my executors, administrators, and assigns, or such
others as I, the said William Fawcett, 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 3
Kingdom of Great Britain and Ireland, the Channel Islands, and Isle of
Man, an Invention for "AN IMPROVED FUEL ECONOMIZER AND HEATING OR
STOVING APPARATUS," upon the condition (amongst others) that I, the
said William Fawcett, my executors or administrators, by an instrument

page_text: 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 immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Willinm Fawcett, 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, reference being had to the accompanying
Drawings, and to the letters of reference marked thereon, that is to
say:-
My Invention is applicable to fire-grates or stoves of ordinary con-
struction used in dwelling houses and other places, and has for its object
the utilization of a great portion of the waste heat which would otherwise,
pass off unemployed up the chimney or flue, by employing it for heating
or stoving in rooms or other places, and is as hereafter described. .
The Invention will be more completely understood by reference to the
accompanying 2 Sheets of Drawings.
Sheet 1 represents the application of my Invention to stoves of
ordinary construction.
Figure 1 is a front elevation of stove; Figure 2 a side elevation;
Figure 3 a back elevation; Figure 4a plan looking at the top; Figures 5.
and 6 shew an arrangement of water tank for the same.
Figs. 7 and 8 are a cross section and plan of stove and boiler combined,
each shewing the application of my Invention.
I provide the tubes or pipes a which may be of any required number
and size; these I arrange in the interior of the stove 6 as shewn, and
carry them below the fire, having the bottom end open and of any
desired form. At the back of the stove I by preference provide the
opening o through which the cold air has access to the bottom of each
tube without coming in contact with the smoke or other gases that
might pass from the fire.
It will be readily understood that the fire in the grate effects the
tubes a which become intensely hot, the air in the tubes thereby
becoming heated ascends and passes off at the top of the tubes into the..

combination with stoves and fire-grates, substantially as and for purposes
herein set forth.
Thirdly. The means employed for conducting the heated air into other
rooms or places, substantially as and for purposes herein set forth.
In witness whereof, I, the said William Fawcett, have hereunto set
my hand and seal, this First day of September, in the year of
our Lord One thousand eight hundred and seventy-three.
