IMPROVEMENTS IN STOVES OR FIRE-GRATES
Year: 1872

page_text: LETTERS PATENT to George Ash, of Great Marlborough Street,
Regent Street, in the County of Middlesex, Surgeon Dentist, for
the Invention of "IMPROVEMENTS IN STOVES OR FIRE-GRATES.”
PROVISIONAL SPECIFICATION left by the said George Ash at the
Office of the Commissioners of Patents, with his Petition, on the
11th November 1872.
I, GEORGE ASH, of Great Marlborough Street, Regent Street, in the
County of Middlesex, Surgeon Dentist, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN STOVES OR FIRE-GRATES," to be as
follows:-
"
The object of this Invention is to so construct and arrange the
constituent parts of stoves or fire-grates especially those of the " open'
kind, that each fresh feed of fuel may immediately upon being supplied
to the stove or grate (which can be effected at the top if that usual
mode be preferred) be placed at the bottom of the stove or grate, and

page_text: thus the fresh unignited fuel will be prevented from generating smoke,
as the products of combustion will be burnt or consumed by the mass
of matter already well ignited which remains above the fresh feed.
The above object I effect by making the fire-grate (or a fire-cage)
in circular or nearly circular form, and fitting the same upon a central
pin or axis or axes upon which the grate or cage may be turned, the
upper part of this fire-grate or cage having an opening through which
the fuel can be introduced, which opening may be closed by a door or
by travelling in a solid circular guide or against a plate. Thus when
fuel has to be charged the same can be introduced at the top opening,
then the poker can be applied and the grate made to revolve, when the
opening and fresh fuel will be brought to the bottom.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said George Ash in the Great Seal Patent Office on
the 10th May 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
Asn, of Great Marlborough Street, Regent Street, in the Connty of
Middlesex, Surgeon Dentist, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eleventh day of November, 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 graut unto me, the said George Ash, Her special licence that I,
the said George Ash, my executors, administrators, and assigns, or such
others as I, the said George Ash, 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 STOVES OR FIRE-
GRATES," upon the condition (amongst others) that I, the said George
Ash, 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

page_text: 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 George Ash, 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 :-
The object of this Invention is to so construct and arrange the
constituent parts of stoves or fire-grates, especially those of the open
kind, that each fresh feed of the fuel may immediately upon being
supplied to the stove or grate (which can be effected at the top thereof
if that usual mode be preferred) by suitable movement be placed at the
bottom of the stove or grate, and thus the fresh unignited fuel will be
prevented from generating smoke as the products of combustion will be
burnt or consumed by the mass of matter already well ignited, which is
placed by the said movement above the fresh fuel.
The above object I effect by making the fire-grate (or a fire-cage) in a
circular or nearly circular form, and fitting the same upon a central pin
or axis or axes, upon which the grate or cage may be turned, the upper
part of this fire-grate or cage having an opening through which the
fuel can be introduced, which opening may be closed by a door or by
travelling in a solid circular guide or against a plate. Thus when fresh
fuel has to be supplied the same may be introduced at the top opening,
then the poker or a lever can be applied and the grate made to revolve,
when the opening and fresh fuel will be brought to the bottom, the said
opening being first closed by shutting the door when no closing guide is
provided.
For the better exemplification of the nature and object of the said
Invention and to particularly describe and ascertain in what manner the
same is to be performed or carried out in practice, I will now describe
the said Invention more in detail by referring to the Drawings accom-
nanving this Specification as follow

page_text: back works in a guide, as shewn. Fig. 2, section of Figure 1. Fig. 3,
back view of Figure 1.
Fig. 4, front view of an arrangement in which a grate or cage is sup-
ported on axes one at each side.
Fig. 5, front view of another arrangement where the grate is supported
on two axes, one at back and the other in front.
In said Drawing A denotes the grate; B, axis or axes; and in the
arrangement shewn in Figs. 1 and 2 C denotes the guide for grate, and D,
feeding plate, which closes the opening at top of grate when no door is
used. In Fig. 5 E denotes a bracket proceeding from the back to the
front of grate and forming the bearing for the axis in front, as shewn.
Having now particularly described and ascertained the nature and
object of my Invention, and in what manner the same is to be performed
or put in practice, I hereby declare that I claim the herein described
Invention of improvements in stoves or fire-grates as the same is
herein-before set forth and described, it being understood that I do not
limit myself to the exact details of construction shewn by the Drawings
and herein described, as the same may be varied as may be found
desirable without departure from the essential character of my said
herein described Invention.
In witness whereof, I, the said George Ash, have hereunto set my
hand and seal, this Tenth day of May, in the year of our Lord One
thousand eight hundred and seventy-three.
