Year: 1868

page_text: LETTERS PATENT to Amos Harris, of Thame, in the County of
Oxfordshire, Ironmonger, for the Invention of "IMPROVEMENTS IN
HEATING APPARATUS FOR WARMING CHURCHES, CHAPELS, AND OTHER PUBLIC
AND PRIVATE BUILDINGS BY HOT AIR."
Sealed the 25th May 1869, and dated the 26th November 1868.
PROVISIONAL SPECIFICATION left by the said Amos Harris at the
Office of the Commissioners of Patents, with his Petition, on the
26th November 1868.
I, AMOS HARRIS, of Thame, in the County of Oxfordshire, Ironmonger,
do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN HEATING APPARATUS POR WARMING CHURCHES, CHAPELS, AND OTHER PUBLIC
AND PRIVATE BUILDINGS BY HOT AIR," to be as follows, to be as follows:-
This Invention consists of a circulating atmospheric hot-air stove or
heating apparatus, causing an equilization of temperature throughout the
building; it is most effective, economical in fuel, and perfectly safe for
boarded floors.

page_text: My said Invention will be properly understood by reference to the
accompanying Drawings, wherein the same letters of reference indicate
similar parts in each of the Figures.
Figure 1 represents a sectional elevation.
A, the fire-box, with ash-pit B; from the top of the fire-box a number
of pipes C, C, C, varying from three & upwards (according to size of
apparatus terminates in a smoke box D, thence into a chimney E. The
external cold air is introduced by a pipe or air passage F into the ash-pit B
to the fire, up thro' the smoke pipes into the smoke box, and up the
chimney E, and can be stopped off by valves at pleasure. The air is con-
ducted from the most extended and coldest parts of a building through
pipes or air passages (regulated by ventilators) into an air chamber
of my apparatus marked H, formed in the lowest portion of the same,
passing thro' openings (I) into the space S, S, forming the exterior of
the fire-box, circulating round the same and the pipes, it then passes out
at the top or sides of the apparatus thro' apertures or gratings J into
the building, causing a continual circulation of hot air throughout.
Cold air is likewise supplied a the bottom of outer casing thro' the
pipe K for ventilation, and is stepped off by a valve L at pleasure. At
the top of the smoke box is a vessel M, in which water is placed, by the
evaporation of which the hot air is moistened before passing out thro'
gratings J. In the smoke box D is fitted a valve plate N, which will
distribute the heat thro' the same after passing through pipes, so as not
to be drawn immediately to pipe E. Fig. 2, plan view at O, P; Fig. 3,
plan view at O, R. The apparatus can be fixed out in the open air, or
in brickwork, as most convenient.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Amos Harris in the Great Seal Patent Office on the
26th May 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, AMOS 3
HARRIS, of Thame, in the County of Oxfordshire, Ironmonger, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-sixth day of November, in the
year of our Lord One thousand eight hundred and sixty-eight, in the 3

page_text: thirty-second year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Amos Harris, Her special
licence that I, the said Amos Harris, my executors, administrators,
and assigns, or such others as I, the said Amos Harris, 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
HEATING APPARATUS FOR WARMING CHURCHES, CHAPELS, AND OTHER PUBLIC AND
PRIVATE BUILDINGS BY HOT AIR," upon the condition (amongst others)
that I, the said Amos Harris, my exccutors or administrators, by an
instrument in writing under my, or their, or one of their hands and
scals, 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 Amos Harris, 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:-
This Invention consists of a circulating atmospheric hot-air stove or
heating apparatus, causing an equalization of temperature throughout
the building; it is most effective, economical in fuel, and perfectly safe
for boarded floors.
My said Invention will be properly understood by reference to the
accompanying Drawings, wherein the same letters of reference indicate
similar parts in each of the Figures.
Fig. 1 represents a sectional elevation.
A, the fire-box, with ash-pit B; from the top of this fire-box a
quantity of round, square, or any other shape pipes C, C, C, varying
in number from three and upwards (according to size of apparatus)
terminates in a smoke box D, thence into a chimney E. The external
cold air is introduced by a pipe or air passage F into the ash-pit B to
the fire, up through the smoke pipes into the smoke-box, and up the
chimney E, and can be stopped off by valve G at pleasure. The air is
conducted from the most extended and coldest parts of a building

page_text: through pipes or air passages (regulated by ventilators or gratings) into
an air chamber of my apparatus marked H, formed in the lowest portion
of the same, passing through openings I, see also Fig. 2, into the
space S, S, forming the exterior of the fire-box, circulating round the
same and between the pipes, it then passes out at the top or sides of the
apparatus through apertures or gratings J into the building, causing a
continual circulation of hot air throughout the building. Cold air is
likewise supplied at the bottom of outer casing through the pipe K for
ventilation, and is stopped off by a valve L at pleasure. At the top of
the smoke box is a vessel M, in which water is placed, by the evaporation
of which the hot air is moistened before passing out through gratings J.
In the smoke box D is fitted a valve plate N, which will distribute the
heat through the same after passing through pipes, so as not to be drawn
immediately to pipe E. Fig. 2, plan view at O, P; Fig. 3, plan view
at Q, R. The apparatus can be fixed out in the open air by having an
iron outer casing, or in brickwork, as most convenient, of any ornamental
design.
In witness whereof, I, the said Amos Harris, have hereunto set
my hand and seal, this Twenty-sixth day of May, in the year
of our Lord One thousand eight hundred and sixty-nine.
AMOS HARRIS. (L.s.)
