page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
STRATTON, of Frederick's Place, Hampstead Road, in the County of Mid-
dlesex, Gentlemen, send greeting.
WHEREAS His most Excellent Majesty King George the Fourth, by His
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Twenty-eighth day of August, in the ninth year of His reign, did, for
Himself, His heirs and successors, give and grant unto me, the said George
Stratton, His especial licence that I, the said George Stratton, my executors,
adñiors, and assigns, or such others as I, the said George Stratton, my exors,
adiiors, or assigns, should at any time agree with, and no others, from time to
time and at all times hereafter 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 "AN IMPROVEMENT IN
WARMING AND VENTILATING CHURCHES, HOTHOUSES, AND OTHER BUILDINGS,
WHICH IMPROVEMENT MAY BE APPLIED TO OTHER PURPOSES;" in which said
Letters Patent is contained a proviso obliging me, the said George Stratton,
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 His Majesty's
High Court of Chancery within six calcndar months next and immediately

page_text: after the date of the said recited Letters Patent, as in and by the same,
reference being had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
George Stratton, do hereby. declare that the nature of my said Invention, and
the manner in which the same is to be performed, is described and ascertained
as follows (that is to say):-
My Improvements in Warming and Ventilating Churches, Hothouses, and
other Buildings consist in the construction of an apparatus having one or
more spiral channels through which atmospheric air is to be passed, these
spiral channels being surrounded by a hot medium produced by a close vessel
containing steam. The manner in which I construct my improved apparatus
is shewn in the Drawing hereunto annexed, in which Fig. 1 is an external
view of the heating apparatus, Fig. 2 is a section of the same taken vertically,
and Fig. 3 a horizontal view of the same, the top being removed to shew the
interior. It is contained in a hollow pedestal, which may be of any convenient
form dictated by fancy or taste; that is, circular, triangular, square, or
polygonal. The most simple construction of the apparatus is that exhibited
by the three first Figures, in which the contrivance is adapted to a cylindrical
chamber or box. a, a, is the outer case or hollow pedestal enclosing the
apparatus. b, b, is a cylinder within the pedestal having another cylinder c, c,
within it, which contains the spiral d, d. The cylinders b and c are made of
sheet copper or any other suitable material, and being connected together at
top and bottom, and the ends of the passage between them closed, form a
close cylindrical box or channel for the reception of steam. A pipo e, which
communicates with a boiler, conducts. the steam into the cylindrical box. or
channel b, by which a heated medium is made to encompass the cylinder c
containing the spiral d, and any water which may accumulate by the partial
condensation of the steam runs off to the boiler or elsewhere by the pipe f.
In the bottom of the pedestal there is an opening for the admission of
atmospheric air, which, passing upwards, proceeds through the winding
passage of the spiral, and becoming heated in its progress, and is passed off at
top into the open part of the pedestal, and thence is disseminated through the
ventilator 9 into the building or apartment intended to be licated. A per-
pendicular pipe h passes up the center of the spiral as a support to the several
coils of the sheet metal by which the winding passage is formed. This pipe 3
communicates at top and bottom by means of short horizontal pipes with
the steam chamber b, and by that means allows the steam to circulate
through the center of the spiral for the purpose of assisting to heat the air
in its progress. The ventilator is formed by two perforated circular plates

page_text: sliding round upon their centre, or by other sliding apparatus of the same
kind, by which the quantity of heated air passed from the apparatus may be
regulated.
Having described the mode of constructing my improved heating apparatus
in its most simple form, I now proceed to state the manner in which I adapt
several of these spirals in one pedestal or steam box for the purpose of
increasing the quantity of air heated and passed through an apparatus of this
description. Fig. 4 is a horizontal section of a circular steam box b, b, b, with
four of the cylinders c, c, c, c, passed through it, each containing one of the
spirals d, constructed with pipes, and forming spiral channels, exactly as
described with reference to Figs. 2 and 3. Any number of these spirals may
be inserted in this way in a close steam box of any convenient shape, the
steam being conducted from a boiler and admitted by a pipe i in the centre or
elsewhere, and the atmospheric air being passed from below through the spiral
channels in the manner before explained, and discharged through a ventilator
at top.
In witness whereof, I, the said George Stratton, have hereunto set my
hand and seal, this Twenty-eighth day of February, in the year of our
