IMPROVED APPARATUS FOR HEATING CONSERVATORIES, CHURCHES, AND OTHER BUILDINGS
Year: 1874

page_text: LETTERS PATENT to Charlos Ezard, of Manchester, in the County of
Lancaster, for the Invention of "IMPROVED APPARATUS FOR HEATING
CONSERVATORIES, CHURCHES, AND OTHER BUILDINGS."
Sealed the 5th December 1874, and dated the 9th October 1874.
PROVISIONAL SPECIFICATION left by the said Charles Ezard at the
Office of the Commissioners of Patents, with his Petition, on the
9th October 1874.
I, CHARLES EZARD, of Manchester, in the County of Lancaster, do
5 hereby declare the nature of the said Invention for "IMPROVED APPARATUS
FOR HEATING CONSERVATORIES, CHURCHES, AND OTHER BUILDINGS," to be as
follows:-
This Invention consists principally in heating conservatories, churches,
and other buildings, by carrying the heat generated by the burning of
coal, coke, gas, or other combustibles, by means of an internal pipe
passing through the whole length or any part thereof of the pipes used

page_text: to convey and circulate the heated water to and from the place where
such heat is generated, the object of the Invention being to utilize to
the utmost the heat of whatever kind employed, thereby effecting a
great saving in the amount of coal gas or other fuel used in the process
of heating.
For the sake of illustration I will here describe one form of applying
the Invention for heating small conservatorics by burning coal gas, and
it will be at once seen that the heat being carried through the interior
of the water pipe will be nearly all absorbed by the water surrounding
the flue pipe, which pipe or flue may be carried in a similar way through
any number or length of water pipes.
"
The lamp, stove, or other means of heating may be of any suitable
form, but in this case I prefer to employ a lamp on the "Bunsen
principle for burning coal gas, which is supplied through an india-rubber
or other tube fixed thereto. Above the burner is a conc-shaped com-
bustion chamber of iron, copper, or other material joined to and forming
a continuation of the flue pipe, which latter passes through the water
pipe and through the cistern at the other end. Through this internal
flue pipe the heated gases are carried by the draft, and finally escape up
a chimney or pipe into the open air. This pipe however may be carried
in any direction in and around the conservatory till what little of heat
remains in it is entirely exhausted; or it may be carried through the
hot water return pipe, as there is practically no limit to the application
of the principle, but the length of water piping used. If the flue pipe
gets foul by the accumulation of soot there is a plug at the cistern end
thereof, which may be removed, and a brush or other instrument pushed
in the whole length. The combustion chamber can be cleaned out by
withdrawing the lamp.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Charles Ezard in the Great Seal Patent Office on 30
the 8th April 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
EZARD, of Manchester, in the County of Lancaster, send greeting.

page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Ninth day of October, in the year of
our Lord One thousand eight hundred and seventy-four, in the thirty-
eighth year of Her reign, did, for Herself, Her heirs and successors,
3 give and grant unto me, the said Charles Ezard, Her special licence
that I, the said Charles Ezard, my executors, administrators, and
assigns, or such others as I, the said Charles Ezard, 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 "IMPROVED APPARATUS
FOR HEATING CONSERVATORIES, CHURCHES, AND OTHER BUILDINGS," upon the
condition (amongst others) that I, the said Charles Ezard, 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 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 Charles Ezard, do hereby declare
the nature of the said Invention, and in what manner the same is
to be performed, to be particularly described and ascertained in and
by the following statement and accompanying Drawings (that is to
say) :-
This Invention consists principally in heating conservatories, churches,
and other buildings, by carrying the heat generated by the burning of
coal, coke, gas, or other combustibles by means of an internal pipe
passing through the whole length or any part of the pipes used to
convey and circulate the heated water to and from the place where such
heat is generated, the object of the Invention being to utilize to the
utmost the heat of whatever kind employed, thereby effecting a great
saving in the amount of coal gas or other fuel used in the process of
heating.
Such being the nature and object of my said Invention I will now
་་
---

page_text: the same may be clearly understood I have annexed hereunto a Sheet of
Drawings illustrative thereof, and have marked the same with figures
and letters of reference corresponding with those in the following
explanation thereof :-
For the sake of illustration I will here describe one form of applying |
the Invention for heating small conservatories by burning coal gas, and
it will at once be seen that the heat being carried through the interior of
the water pipe will be nearly all absorbed by the water surrounding the
flue pipe, which pipe or flue may be carried in a similar way through
any number or length of water pipes.
The Drawing represents (partly in elevation and partly in section) a
heating apparatus constructed according to my Invention.
The lamp, stove, or other means of heating may be of any suitable
form, but in this case I prefer to employ a lamp a, a, on the Bunsen
principle for burning coal gas, which is supplied through an india-rubber
or other tube b, b, fixed thereto. Above the burner is a cone shaped
combustion chamber c, c, of iron, copper, or other material joined to and
forming a continuation of the flue pipe d, d, which latter passes through
the water pipe e, e, and through the cistern f, f, at the other end.
Through this internal flue pipe d, d, the heated gases are carried by the
draft, and finally escape up a chimney or pipe 9, 9, into the open air.
This pipe 9, 9, however may be carried in any direction in and around
the conservatory till what little of heat remains in it is entirely
exhausted; or it may be carried through the hot water return pipe h, h,
as there is practically no limit to the application of the principle, but
the length of water piping used. If the flue pipe d, d, gets foul by the
accumulation of soot there is a plug i, i, at the cistern end thereof,
which may be removed and a brush or other instrument pushed in the
whole length. The combustion chamber c, c, can be cleaned out by
withdrawing the lamp.
Having now described the nature and object of my said Invention,
together with the manner in which is the same is to be or may be
performed or carried into practical effect, I wish it to be understood that
I claim as my Invention, the above described construction of heating
apparatus, wherein the internal flue pipe passes through the whole or
any part of the pipes used to convey and circulate the heated water
to and from the place whence the heat is generated, whether the fuel-

page_text: employed to generate the heat be coal, coke, gas, or other com-
bustible.
In witness whereof, I, the said Charles Ezard, have hereunto set
my hand and seal, this Sixth day of April, in the year of our
Lord One thousand eight hundred and seventy-five.
