Year: 1872

page_text: LETTERS PATENT to William Walker, of the Victoria Iron Works,
Walmgate, in the City of York, for the Invention of "IMPROVEMENTS
IN CONNECTION WITH STOVEs for the PoRPOSE OF ECONOMISING FUEL. ”
IN CONNECTION WITH STOVES FOR THE PURPOSE OF ECONOMISING FUEL ""
PROVISIONAL SPECIFICATION left by the said William Walker at the
Office of the Commissioners of Patents, with his Petition, on the
23rd October 1872.
I, WILLIAM WALKER, of the Victoria Iron Works, Walmgate, in the
City of York, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN CONNECTION WITH STOVES FOR THE PURPOSE OF ECONOMISING
FUEL," to be as follows:-
The object of this Invention is to reduce the amount of fuel burnt in
ordinary sitting room and bed room fire-places with a view of economising
fuel, whilst at the same time giving a cheerful fire. For this purpose
I place at the back of the fire-grate a metal casting which rests upon
the fire-bars and against the back of the grate, as shewn in the Drawing
hereunto annexed. In this Drawing the metal casting, which I call the
"coal saver," is marked A. It is made with closed ends, and is by
preference of a width less than the distance between the two sides of
the fire-place so as to leave a space between its ends and these sides.
The outer face of the casting has a number of grooves or channels A¹

page_text: formed in it, and may also have holes formed through it to allow air to
pass to the fuel from the back. By placing a casting of this description
at the back of an ordinary fire-grate the space occupied by the fuel is
reduced, whilst at the same time the extent of burning fuel visible from
the room is not lessened.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Walker in the Great Seal Patent Office
on the 23rd April 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
WALKER, of the Victoria Iron Works, Walmgate, in the City of York,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her.
Letters Patent, bearing date the Twenty-third day of October, .in the
year of our Lord One thousand eight hundred. and seventy-two, in the
thirty-sixth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said William Walker, Her special
license that I, the said William Walker, my executors, administra-
tors, and assigns, or such others as I, the said William Walker, 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 CONNECTION WITH STOVES FOR THE PURPOSE OF ECONOMISING FUEL," upon the
condition (amongst others) that I, the said William Walker, my exe-
cutors or administrators, by an instrument in writing under my, or their,
or one of their hands and seals, should particularly describe and ascer-
tain 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 William Walker, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement thereof, that is to say :-

page_text: The object of this Invention is to reduce the amount of fuel burnt in
ordinary stoves or fire-places (such as sitting room and bed room fire-
places or kitchen ranges) with a view of economising fuel, whilst at the
same time giving a bright and cheerful fire. For this purpose I place
at the back of the fire-grate a metal casting which rests upon the bottom
grate and against the back as shewn at Figure 1 of the Drawings here-
unto annexed. In this Figure the metal casting, which I call the "coal
saver," is marked A.
>>
Separate views of a coal saver suitable for a sitting room fire-place
are shewn on a larger scale at Figures 2, 3, and 4. The "coal saver
is made by preference with closed or partly closed ends, and is also by
preference of a width less than the distance between the two sides of
the fire-place, so as to leave a space between its ends and these sides.
The outer face of the casting has a number of grooves or channels A¹
formed in it, and may also have slots or holes B formed through it to
allow air to pass to the fuel from the back. C, C, are strengthening
flanges at the top and bottom of the casting. By placing a casting of
this description at the back of an ordinary fire-grate the space occupied
by the fuel is reduced, whilst at the same time the extent of burning
fuel visible from the room is not lessened, as the coal saver forms as it
were a hollow back of a height less than the fixed back of the grate, and
is completely covered by the burning fuel.
Having thus described the nature of my Invention and the manner of
performing the same, I would have it understood that what I claim as
my improvements in connection with stoves for the purpose of econo-
mising fuel is the manufacture of a "coal saver substantially as herein
described and illustrated in the Drawings annexed.
"
In witness whereof, I, the said William Walker, have hereunto
set my hand and seal, this Sixteenth day of April, in the
year of our Lord One thousand eight hundred and seventy-three.
WILLIAM WALKER. (L.S.)
