AN IMPROVED APPA- RATUS FOR EFFECTING THE SAVING OF FUEL USED FOR DOMESTIC PURPOSES.
Year: 1872

page_text: LETTERS PATENT to William Green, of Birmingham, in the County
of Warwick, Machinist, for the Invention of "AN IMPROVED APPA-
RATUS FOR EFFECTING THE SAVING OF FUEL USED FOR DOMESTIC PURPOSES.
Sealed the 25th February 1873, and dated the 28th August 1872.
PROVISIONAL SPECIFICATION left by the said William Green at the
Office of the Commissioners of Patents, with his Petition, on the
28th August 1872.
I, WILLIAM GREEN, of Birmingham, in the County of Warwick,
Machinist, do hereby declare the nature of the said Invention for "AN
IMPROVED APPARATUS FOR EFFECTING THE SAVING OF FUEL USED FOR DOMESTIC
PURPOSES," to be as follows, that is to say :-
My Invention consists of a solid frame of bars of cast or wrought iron,
or any other suitable metal. Upon one edge I form a projecting flange
or ledge, which will rest upon and against any of the front bars of a fire-
grate. The frame is made so that it will rest in a sloping position
against the back of the fire-grate, the back edge of the frame being
bevelled to allow perfect freedom of expansion and contraction without
any injury to the fire-grate.

page_text: By preference I make the portion of the frame near the front of the
fire-grate of a curved shape, so as to form a bed for the fuel at whatever
angle the frame may be placed.
My Invention further consists of a reflector of tin, or any other
suitable material, which may be hung down at the back of the fire-grate t
underneath the frame. This reflector will be of great use in assisting
to heat the lower part of the room in which the fire-grate is placed.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Green in the Great Seal Patent Office on
the 28th February 1873.
.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
GREEN, of Birmingham, in the County of Warwick, Machinist, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-eighth day of August, 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 succes-
sors, give and grant unto me, the said William Green, Her special
license that I, the said William Green, my executors, adminis-
trators, and assigns, or such others as I, the said William Green,
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 "AN
IMPROVED APPARATUS FOR EFFECTING THE SAVING OF FUEL USED FOR DOMESTIC
PURPOSES," upon the condition (amongst others) that I, the said William
Green, 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 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 Green, do hereby declare
the nature of my said Invention, and in what manner the same is to be

page_text: performed, to be particularly described and ascertained in and by the
following statement, that is to say :—
The nature of my said Invention will be more readily understood by
aid of the Drawings hereunto annexed, reference being had to the letters
and figures marked thereupon.
Figure 1 is a front elevation; and Figure 2, a cross section of an
ordinary kitchen fire-grate with my improved apparatus for effecting a
saving of fuel fitted thereunto; Figures 3 and 4 shew in plan and section
the apparatus half full size, and removed from the grate, Figure 5 being
a modified form of the section, Figure 4.
The apparatus consists of a portable solid frame of bars (a) of cast or
wrought iron, or other suitable metal, and formed in any convenient
manner, being straight in the direction of their length, as shewn in
Figure 1, or tapering as in Figure 3, and having open spaces between of
the width required. The front edge or flange (6) I form with a lip (¹)
to rest upon and against any one of the fire-bars according to the amount
of fire required, the back edge (c) resting against the back of the fire-
place or grate; the apparatus is shewn in Figures 1 and 2 as resting
upon the top bar of the grate, as would be the case when a small fire is
required; for a larger fire the apparatus is lowered on to the next
or one of the other bars. The back edge (c) of the frame is bevilled
to allow perfect freedom of expansion and contraction of the metal
without injury to the fire-grate, and to prevent the burning away of the
back edge (c) I form snugs or projections (d) upon such back edge (c),
which, resting against the fire-place back allow the air to pass up
between the back edge (c) and such fire-place back.
By preference I make the portion of the frame near the front of the
fire-grate of a curved shape in outline, as seen in Figures 2 and 4, so as
to form a bed for the fuel at whatever angle the frame may be placed.
In some cases however I dispense with the curved outline, and form the
frame in section by two or more straight lines meeting each other at an
angle, as shewn in Figure 5.
My Invention further consists in employing in combination with the
frame already described a reflector such as (e) formed of tin or other
suitable metal, and of any required outline, and either fluted, as shown,
or plain, or otherwise shaped upon its surface. This reflector I prefer to
suspend by means of hooks upon the ends of the wires (f), secured into

page_text: eyes at the back edge (c) of the frame (a), the reflector (e) hanging
down at the back of the fire-grate underneath the frame (a), the use of
such reflector being to assist in diffusing heat to the lower part of the
apartment.
Although I have described and illustrated my Invention as applied to
a kitchen fire-grate it may be used for any other description of open
grate, stove, or range; and in adapting my improvements to any parti-
cular shape, such as that of a register fire-grate, I suitably vary the
outline by tapering the sides of the frame (a) or curving the front part,
or otherwise altering the outline of the frame (a) as required.
I also propose using side cheeks having bars in combination with
my improved frame or bed of bars when applying the apparatus to
certain forms of fire-grates, such side cheeks being for the purpose of
contracting the width of the fire, and I connect such side cheeks to the
frame or bed by any convenient means.
Having thus described the object and nature of my said Invention,
and the manner in which the same is to be carried into effect, I
claim, without confining myself to these precise details, the "improved
apparatus for effecting the saving of fuel used for domestic purposes,"
constructed and applied in manner as herein more fully set forth and
specified.
In witness whereof, I, the said William Green, have hereunto set
my hand and seal, this Twenty-sixth day of February, in the
year of our Lord One thousand eight hundred and seventy-
