Year: 1838

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
JEAKES, of Great Russell Street, Bloomsbury, in the County of Middlesex,
Ironmonger, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Twenty-second day of October, in the second year of Her
reign, and in the year of our Lord One thousand eight hundred and thirty-
eight, did, for Herself, Her heirs and successors, give and grant unto me,
the said William Jeakes, Her special licence, full power, sole privilege and
authority, that I, the said William Jeakes, my executors, administrators, and
assigns, or such others as I, the said William Jeakes, my executors, admi-
nistrators, or assigns, should at any time agree with, and no others, from time
to time and at all times during the term of years therein mentioned, should
and lawfully might make, use, exercise, and vend, within England and Wales,
and the Town of Berwick-upon-Tweed, and in all Her Majesty's Colonies
and Plantations abroad, my Invention of "A MODE OF APPLYING VENTILATING
APPARATUS TO STOVES CONSTRUCTED ON DR. ARNOTT'S PRINCIPLE;" in which said
Letters Patent is contained a proviso obliging me, the said William Jeakes,
by an instrument in writing under my hand and seal, particularly to describe
and ascertain the nature of my said Invention, and in what manner the same
is to be performed, and to cause the same to be inrolled in Her Majesty's
High Court of Chancery within six calendar months next and immediately
after the date of the said in part recited Letters Patent, as in and by the same,
reference being thereunto had, will more fully and at large appear.

page_text: NOW KNOW YE, that in compliance with, the said proviso, 1, the said
William Jeakes, do hereby declare that the nature of my said Invention, and
the manner in which the same is to be performed, is particularly described
and ascertained in and by the following description thereof, reference being
had to the Drawings hereunto annexed, and to the letters and figures marked
thereon (that is to say):-
My Invention of a Mode of applying Ventilating Apparatus to Stoves con-
structed on Doctor Arnott's Principle, will be seen by reference to the
Drawing accompanying this my Specification, in which Fig. 1 is an external
view or elevation of the stove; Fig. 2 is a section of the same, taken ver-
tically through the middle of the stove; and Fig. 3, a horizontal section of
the same.
a is the furnace, containing the ignited fuel in the interior of a
box b, b, b, the lower part of which is lined with fire brick at c, c; the grating or
fire bars are shewn at d, and e, e, is the ash pit; the air to support combustion
being admitted through an adjustable ventilator in front of the ash pit; the
fuel is supplied at the door...and the smoke rising into the upper part of
the box, passes off through the lateral pipe.g into the chimney, h. The upper
part of the box b, b, is closed by a lid i, having flanges, which fall into, a
groove filled with sand round the top edge of the box, and forming a sand pack-
ing. Such is the ordinary construction of Doctor Arnott's stove, as described
in his published. treatise on that. subject. Now my Invention, is an improve-
ment on Doctor Annott's stove, consisting of, an appendage by which a current
of cold and pure atmospheric air may be brought in contact with the; sides of
the stove, and after being heated by that means, may be, discharged into the
room for the purpose of warming its atmosphere. I surround the stove
entirely by a casing k, k, k, k, which incloses it, forming air passages all round,
and by means of a pipe or tube l, leading from any convenient opening, intro-
duce atmospheric air, either from without the house or from any other apart-
ment. This air is brought through an opening in the bottom of the casing
at m into the lower part of the chamber, and from thence rises up the pas-
sages n, n, at the sides of the stove, taking up the heat as it passes, and is
ultimately discharged through openings in the top at o, o, into the room.. By
these means a constant current of warm air is supplied to the room, and that
air which is cold, or has been rendered heavy by respiration, is drawn off
through an opening p, and carried up a pipe q into the chimney; thus, a
constant circulation of the air in the room is effected, and a perfect ventilation
obtained, which will be found to be a great relief in a close room where one
of, Doctor Arnott's stoves is used, having, as they always have, the mouth of
the chimney closed at bottom. When it is not required to introduce cold
4

opening m, which shuts off the communication with the pipe or tube l, and
opens an apertures; through this aperture the atmospheric air of the room
now passes in a current up the channels n, n, by the sides of the stove, and
is discharged at top in a heated state, thus producing a circulation of air
which warms the apartment, and if it is not considered necessary to withdraw
the colder or heavier parts of the air from the room, I close the aperture p of
the pipe or tube q, and shut off that communication with the chimney.
In witness whereof, I, the said William Jeakes, have hereunto set my
hand and seal, this Twenty-second day of April, in the year of our
Lord One thousand oight lundred and thinte ning
AND BE IT REMEMBERED, that on the Twenty-second day of April,
in the second year of the reign of Her Majesty Queen Victoria, the said
William Jeakes came before our said Lady the Queen in Her Chancery, and
acknowledged the Instrument aforesaid, and all and every thing therein con-
tained and specified, in form above written. And also the Instrument aforesaid
was stamped according to the tenor of the Statute made in the fifty-fifth year
of the reign of His late Majesty King George the Third.
Inrolled the Twenty-second day of April, One thousand eight hundred
and thirty-nine.
