Year: 1873

page_text: LETTERS PATENT to David Halmshaw, of Park Works, Halifax, in the
County of York, Machino Maker, for tho Invention of "IMPROVE-
MENTS IN THE CONSTRUCTION AND ARRANGEMENT OF FIRE-PLACES OR RANGES,
OVENS, AND BOILERS FOR DOMESTIC USE, FOR RADIATING HEAT AND ECONOMIZING
FUEL."
Sealed the 15th August 1873, and dated the 17th February 1878.
PROVISIONAL SPECIFICATION left by the said David Halmshaw at
the Office of the Commissioners of Patents, with his Petition, on
the 17th February 1873.
I, DAVID HALMSHAW, of Park Works, Halifax, in the County of
York, Machine Maker, do hereby declare the nature of the said Inven-
tion for "IMPROVEMENTS IN THE CONSTRUCTION AND ARRANGEMENT OF FIRE-
PLACES OR RANGES, OVENS, AND BOILERS FOR DOMESTIC USE, FOR RADIATING HEAT
AND ECONOMIZING FUEL," to be as follows :—
This Invention is as follows:-The fire-place or grate is made to
project forward beyond the oven and boiler in ordinary kitchen ranges,
and also in room fire-places, and the projecting sides and bottom, and

page_text: also a portion of the front of such fire-place or grate are perforated, the
remainder of the front having bars arranged in the usual manner. The
back of the said fire-place may also be perforated, and the distance from
back to front varied according to circumstances, but by this construction
the space may be made much less than usual without diminishing the
heat whilst the radiation is greatly increased.
In adapting my improvements to fire-places or ranges in present use,
I apply a perforated plate in front of the bars with anothor plate not
perforated, extending backward and covering over the old fire-place,
which plate may be used as a receptacle for coals, or by forming a flue
through the old back; this plate may be used as a hot hearth, by which
arrangement smoke is consumed (the new fire range with its projecting
perforated sides and bottom being fixed in front of the said perforated
back), thus the fire-place will project further into the room than hercto-
fore by the depth or extent of the old one. The oven and boiler are to
be made of wrought iron welded, and the boiler to be tinned inside.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said David Halmshaw in the Great Seal Patent Office on
the 16th August 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, DAVID
HALMSHAW, of Park Works, Halifax, in the County of York, Machine
Maker, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventeenth day of February, 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 graut unto me, the said David Halmshaw, Her special licence that I,
the said David Halmshaw, my executors, administrators, and assigns, or"
*such others as I, the said David Halmshaw, 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 THE CONSTRUCTION AND

page_text: ARRANGEMENT OF FIRE-PLACES OR RANGES, OVENS, AND BOILERS FOR DOMESTIC USE,
FOR RADIATING HEAT AND ECONOMIZING FUEL," upon the condition (amongst
others) that I, the said David Halmshaw, my executors or adminis-
trators, 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 David Halmshaw, do hereby declare
the nature of my said Invention, and in what manner the same is to
bo performed, to be particularly described and ascertained in and by
the following statement and accompanying Sheet of Drawings, that is
to say:
-
This Invention is as follows:-The fire-place or grate is made to
project forward beyond the oven and boiler in ordinary kitchen ranges,
and also in room fire-places, and the projecting sides, the bottom, and a
portion of the front of such fire-place or grate are perforated, the
The
remainder of the front having bars arranged in the usual manner.
back of the said fire-place may also be perforated, and the distanco from
back to front varied according to circumstances, but by this construction
the space may be made much less than usual without diminishing the
heat, whilst the radiation will be greatly increased.
In adapting my improvements to fire-places or ranges in present use,
I apply a perforated plate in substitution for the old bars with another
plate perforated, and extending backward over the old fire-place, which
plato may be used as a hot plate, by which arrangement smoke is
consumed. The new fire range with its projecting perforated sides and
bottom being fixed, as above-described, in front of the said perforated
O back the fire-place will project further into the room than heretofore.

page_text: the projecting sides E, E, the bottom F, and a portion of the front G of
such fire-place or grate are perforated, the remainder of the front having
bars arranged in the usual manner. The back of the said fire-place may
also be perforated, and the distance from back to front varied according
to circumstances, but by this construction the space may be made much
less than usual without diminishing the heat, whilst the radiation will
be greatly increased.
In adapting my improvements to fire-places or ranges in present use,
I apply a perforated plate in substitution for the old bars with another
plate H perforated and oxtending backward over the old fire-place, 1
which plate may be used as a hot plate, by which arrangement smoke is
consumed. The now fire range with its projecting perforated sides and
bottom being fixed as above described in front of the said perforated
back, the fire-place will project further into the room than heretofore.
The arrows shew the flue courses to the oven and boiler.
Having thus fully described the nature and particulars of this my said
Invention, I would have it understood that I claim the construction and
arranging of fire-places, or ranges, ovens, and boilers, as hercin-described
and shewn in the Drawings.
In witness whercof, I, the said David Halmshaw, have hereunto set 2
my hand and seal, this Ninth day of August, in the year of our
Lord One thousand eight hundred and seventy-three.
DAVID HALMSHAW.
