IMPROVEMENTS IN FIRE RANGES FOR DWELLING HOUSES."
Year: 1867

page_text: LETTERS PATENT to Edward Knowles Heaps, of Woodhouse Lane, Leeds,
in the County of York, Ironmonger, and Thomas Parkin Moorwood, of
Harleston Iron Works, Sheffield, in the County of York, Ironfounder,
for the Invention of "IMPROVEMENTS IN FIRE RANGES FOR DWELLING
HOUSES."
PROVISIONAL SPECIFICATION left by the said Edward Knowles Heaps
and Thomas Parkin Moorwood at the Office of the Commissioners of
Patents, with their Petition, on the 7th March 1867.
We, EDWARD KNOWLES HEAPS, of Woodhouse Lane, Leeds, in the County
of York, Ironmonger, and THOMAS PARKIN MOORWOOD, of Harleston Iron
Works, Sheffield, in the County of York, Ironfounder, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN FIRE RANGES FOR DWELLING
HOUSES," to be as follows:-
The object of our Invention is to effect economy of fuel.
Our Invention consists, firstly, in making fire grates or stoves such as are
used in sitting and other rooms, so that the bottom grating can be closed.or
opened so as to shut off or admit the supply of air to the fire through the said
bottom grating. This we propose to effect by placing a second grating (or a
plate) beneath the ordinary or fixed grating, such grating or plate being
loose and mounted in such a manner that it can be drawn out or pushed in
(or otherwise opened or closed) so as to open or close the spaces in the fixed

page_text: bottom or grating, and thus admit or shut off the supply of air through the
bottom to the fire.
And, secondly, our Invention consists in placing fire-brick upon the bottom
grating of fire or stove grates, such fire-brick being made either solid or per-
forated as may be required. When perforated the above-described sliding
bottom grate (or plate) may be used to open or close the holes.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Edward Knowles Heaps and Thomas Parkin Moorwood in
the Great Seal Patent Office on the 7th September 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, EDWARD
KNOWLES HEAPS, of Woodhouse Lane, Leeds, in the County of York, Iron-
monger, and THOMAS PARKIN MOORWOOD, of Harleston Iron Works, Sheffield,
in the County of York, Ironfounder, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventh day of March, in the year of our Lord One
thousand eight hundred and sixty-seven, in the thirtieth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto us, the said
Edward Knowles Heaps and Thomas Parkin Moorwood, Her special licence
that we, the said Edward Knowles Heaps and Thomas Parkin Moorwood, our
executors, administrators, and assigns, or such others as we, the said Edward
Knowles Heaps and Thomas Parkin Moorwood, our 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 FIRE RANGES FOR DWELLING HOUSES,"
upon the
condition (amongst others) that we, the said Edward Knowles Heaps and
Thomas Parkin Moorwood, our executors or administrators, by an instrument
in writing under our, or one of our, 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 we, the said Edward Knowles Heaps and Thomas
Parkin Moorwood, do hereby declare the nature of our said Invention, and
in what manner the same is to be performed, to be particularly described

page_text: and ascertained in and by the following statement in writing, and on reference
to the accompanying Sheet of Drawings, that is to say:-
The object of our Invention is to effect economy of fuel.
Our Invention consists, firstly, in making fire-grates or stoves such as are
used in sitting or other rooms so that the bottom grating can be closed or
opened so as to shut off or admit the supply of air to the fire through the said
bottom grating. This we propose to effect by placing a second grating (or a
perforated plate) beneath the ordinary or fixed grating, such grating (or
plate) being loose, and mounted in such a manner that it can be drawn out
or pushed in (or otherwise opened or closed, so as to open or close the spaces
in the fixed bottom or grating, and thus admit or shut off the supply of air
through the bottom grate or grating to the fire.
And, secondly, our Invention consists in placing fire-brick, sandstone, or
fire-stone upon or in place of the bottom grating of fire or stove grates or
ranges, such fire-brick being made either solid or perforated, as may be
required. When perforated, the above-described sliding bottom grate or
plate may be used to open or close the holes.
Such being the nature and object of our said Invention for " Improvements
in Fire Ranges for Dwelling Houses," we will now proceed to describe more
in detail the manner in which the same is to be or may be performed or
carried into practical effect; and in order that the same may be distinctly
understood we have annexed hereunto a Sheet of Drawings illustrative
thereof, and have marked the same with figures and letters of reference
corresponding with those in the following explanation thereof, that is to
say :-
In the annexed Drawing, Figure 1 is a front elevation of a register stove,
illustrating both parts of our Invention, the left-hand half representing stove
No. 1, or the first part of our Invention, and the right-hand half stove No. 2,
or the second part of our Invention; Figure 2 is a vertical section of stove
No. 1 through the line C, D, in Figure 1; and Figure 3 is a horizontal
section of the same through the line A, B.
a, a, is the fire-brick back of the stove, provided with air holes or passages
b, b, through which air passes, and becoming heated mingles with the smoke
as it leaves the fire and causes it to be consumed; c, c, is the ordinary fixed
bottom grate or grating, beneath which is a second grating or perforated
plate d, d, which is capable of being moved to an fro by the lever e, e, so as to
act as a valve and open or close the apertures in the fixed bottom grate or
grating c, c, so as to admit or cut off the supply of air to the fire through the
said fixed bottom grate or grating, as before described.

page_text: Figure 4 is a vertical section of stove No. 2 through the line B, C, in
Figure 1, and Figure 5 is a horizontal section of the same through the line
A, B. In this stove the fire-brick a, a, forms both the back and bottom of
the grate in one piece, the back part being furnished with air passages b, b,
for consuming the smoke, as in the former case, and the bottom part with
perforations c, c; the bottom part, however, may be made separate from the
back if preferred, and may be used either with or without the sliding bottom
grate or perforated plate, above described.
In some cases we also propose to make the bottom part solid, in which case
the sliding grate or perforated plate will of course not be used.
Having now described the nature and object of our said Invention for
Improvements in Fire Ranges for Dwelling Houses," together with the
manner in which the same is to be or may be performed or carried into
practical effect, we would remark, in conclusion, that we claim as our
Invention,―
Firstly, the construction and use of the sliding or movable grating or
perforated plate, as above described:
And, secondly, the use of fire-brick, sandstone, or fire-stone (either per-
forated or otherwise) upon or in place of the bottom grate in stove grates or
ranges, whether such fire-brick, sandstone, or fire-stone bottom be used by
itself or in combination with the said sliding or movable grating or perforated
plate.
In witness whereof, we, the said Edward Knowles Heaps and Thomas
Parkin Moorwood, have hereunto set our hands and seals, this Sixth
day of September, in the year of our Lord One thousand eight hundred
and sixty-seven..
