CERTAIN IMPROVEMENTS IN REGISTER STOVES
Year: 1839

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
STEVENS, of Stowmarket, in the County of Suffolk, Brewer, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Twenty-second day of January, in the second year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
George Stevens, Her especial license, full power, sole privilege and authority,
that I, the said George Stevens, my exors, adññiors, and assigns, or such
others as I, the said George Stevens, my exors, adñiors, 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 expressed, should and lawfully might make,
use, exercise, and vend, within England, Wales, and the Town of Berwick-
upon-Tweed, my Invention of "CERTAIN IMPROVEMENTS IN REGISTER STOVES;"
in which said Letters Patent is contained a proviso that I, the said George
Stevens, shall cause a particular description of the nature of my said Invention,
and in what manner the same is to be performed, to be inrolled in Her
said 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.
NOW KNOW YE, that in compliance with the said proviso, I, the said
George Stevens, do hereby declare the nature of my said Invention, and the
manner in which the same is to be performed, are particularly described and

page_text: the Drawings hereunto annexed, and to figures and letters marked thereon,
that is to say-
The intention of my said Invention is to produce the greatest possible heat
from a given quantity of fuels, having due regard to a healthy circulation of
the air within the room, and likewise to the wishes of the community by
allowing the fire to be exposed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a front elevation of the stove. A is the grate for the fuel;
B is the door for the introduction of the fuel; C, C, are the regulators for the
ventilation of the room, which can be opened or shut at pleasure; D, D, are
pipes or tubes for the admission of cold air to the back of the stove, to prevent
the burning away of the back plate or fire-stone; which partly lines the back
of the grate; the air enters at the bottom of the stove, passes up to the top of
the stove, as shewn by the red arrows; it then descends and passes through
holes perforated in the fire stone and makes its escape upwards into the flue;
E is the regulator for the fire, by which the temperature of the fire is increased
or decreased at pleasure down to a low red heat, below which it is dangerous
to go, as the gases would descend into the room instead of ascending up
the chimney: The same letters of reference denote similar parts in- all the
Figures.
Figure 2 is an elevation with the front taken off. A is the grate; F is the
entrance to the flues, the course of the flues is represented by the arrows';
E is the regulating valve, after passing which the hot air makes its escape up
the chimney; G is a valve which is opened at the first lighting of the fire
to cause a more rapid draught, till the cold air is expelled from the flues,,
when it is closed.
Figure 3 is a bird's-eye view of the stove. H, H, H, H, are the flues;
A is the grate; I shews the passage down which the cold air passes, as men-
tioned in the description of Figure 1. This Figure (Figure 3) represents the
stove with the flues cast on the front whole.
Figure 4 represents the same view, with the sides of. the flues cast on the
front, and with the back to be screwed on to the sides.
Figure 5 represents the same view with the sides, cast on the front; the
stove is then bedded against brickwork, which forms the back of the flue..
By these descriptions it will be seen certain advantages accrue; the heated
air, after it has left the fire, has to pass over several feet of surface exposed to
the room (into which the heat is radiated) before it makes its exit into the

page_text: chimney; nearly the whole of the front, as is shewn by Figure 2, is a radiating
surface. The warm air of the room is allowed to escape only at a sufficient
rate to produce a healthy circulation of the air, whereas in the common stove
it is under no control, and a considerable portion of heat is lost; by this means,
as the aperture is small for the escape of the air, the unpleasantness of a rush
of cold air from without, when a door is opened, is prevented. The consump-
tion of the fuel is regulated at pleasure, according to the degree of temperature
that is required; the stove is best adapted for the burning of coke, but other
fuels may be used, as openings are left for the cleaning of the flues; all the
advantages combined, a saving of from one hundred and fifty to two hundred
per cent. is effected; the cost for one day averages about threepence in a
common-sized room.
In witness whereof, I, the said George Stevens, have hereunto set my
hand and seal, this Nineteenth day of July, in the year of our Lord
One thousand eight hundred and thirty-nine.
AND BE IT REMEMBERED, that on the Nineteenth day of July, in
the year of our Lord 1839, the aforesaid George Stevens came before our said
Lady the Queen in Her Chancery, and acknowledged the Specification afore-
said, and all and every thing therein contained and specified, in form above
written. And also the Specification aforesaid was stamped according to the
tenor of the Statute made for that purpose.
