IMPROVEMENTS IN APPARATUS FOR HEATING CONSERVATORIES, APARTMENTS, OR BOILERS BY MEANS OF GAS
Year: 1866

page_text: LETTERS PATENT to Theophilus Alfred Gilbert Willington, of Rose
Hill, Handsworth, Staffordshire, for the Invention of "IMPROVEMENTS
IN APPARATUS FOR HEATING CONSERVATORIES, APARTMENTS, OR BOILERS
BY MEANS OF GAS."
Sealed the 31st July 1866, and dated the 3rd February 1866.
PROVISIONAL SPECIFICATION left by the said Theophilus Alfred
Gilbert Willington at the Office of the Commissioners of Patents, with
his Petition, on the 3rd February 1866.
I, THEOPHILUS ALFRED GILBERT WILLINGTON, of Rose Hill, Hands-
worth, Staffordshire, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN APPARATUS FOR HEATING CONSERVATORIES, APARTMENTS,
OR BOILERS BY MEANS OF GAS," to be as follows:-
I employ two or more heating, chambers or stoves which are internally
heated by gas jets. For heating conservatories or places of moderate size
two heating stoves or chambers will be found sufficient; they are connected
together by a pipe or tube for the passage of the air, which is conducted
round the place required to be heated. One of the chambers I make
larger than the other, and heat it with a greater number of gas jets; this,
to distinguish it, may be termed the inlet heating chamber, as I connect it
by means of an inlet pipe with the open air. At the other end of the pipe
or tube above mentioned I fix the second and smaller heating chamber or
stove, in which a small number of gas jets are burned, and which may be
called the outlet heating chamber, as it is connected with the open air by

page_text: an outlet pipe. The action of the heating apparatus is as follows:-The
combustion of the gas in the smaller or outlet chamber causes it to act as
an exhaust and draw a current of heated air through the connecting pipe
or tube from the larger heating chamber. The latter, in which a larger
number of gas jets are burned, is constantly delivering volumes of heated
air, which pass through the tube and are drawn into the outlet heating
chamber and then passed on into the open air. To insure a constantly
active circulation of the heated air the inlet pipe is laid in or near the floor of
the place to be heated, and the outlet pipe may be fixed in or near the roof.
The number of gas jets in the smaller or outlet chamber will be propor-
tioned to the number used in the larger or inlet chamber. When requisite,
in the case of a very long range of heating pipes or tubes, one or more
intermediate heating chambers may be used; they should-be so placed and
contain such a number of jets that the current of air which may have
given off its heat during transmission receives additional heat from the
intermediate heating chamber and is always urged in one direction.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Theophilus Alfred Gilbert Willington in the Great
Seal Patent Office on the 3rd August 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THEOPHILUS
ALFRED GILBERT WILLINGTON, of Ross Hill, Handsworth, Staffordshire,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Third day of February, in the year of our
Lord One thousand eight hundred and sixty-six, in the twenty-ninth
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said Theophilus Alfred Gilbert Willington, Her
special licence that I, the said Theophilus Alfred Gilbert Willington,
my executors, administrators, and assigns, or such others as I, the said
Theophilus Alfred Gilbert Willington, 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 APPARATUS FOR
HEATING CONSERVATORIES, APARTMENTS, OR BOILERS BY MEANS OF GAS," upon

page_text: the condition (amongst others) that I, the said Theophilus Alfred Gilbert
Willington, 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 Theophilus. Alfred Gilbert Willington,
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 thereof, reference being had to the
Figures on the accompanying Sheet of Drawings, and to the letters of
reference marked thereon (that is to say) :-
I employ two or more heating chambers or stoves which are internally
heated by gas jets. The heating stoves or chambers are connected together
by a heating pipe or tube conducted round the place which is required to
be heated. One of the chambers I make larger than the other, and heat it
with a greater number of gas jets; this, to distinguish it, may be termed the
inlet heating chamber, as I connect it by means of an inlet pipe with the
open air. To the inlet heating chamber is attached one end of the heating
pipe or tube, and when the apparatus is used for heating conservatories
or other places of moderate size I fix at or near the other end of the,
heating pipe a second and smaller heating chamber or stove in which a
smaller number of gas jets are burned, and which may be called the outlet
heating chamber as it is connected with the open air by an outlet pipe.
The action of the heating apparatus is as follows:-The combustion of the
gas in the smaller or outlet chamber causes it to act as an exhaust and draw.
a current of heated air through the connecting pipe or tube from the larger
heating chamber. The latter, in which a larger number of gas jets are
burned, is constantly delivering volumes of heated air, which are urged
and pass through the tube, and are drawn into the outlet heating chamber
and then passed on into the open air. To insure a constantly active cir-
culation of the heated air the inlet pipe may be laid in or near the floor of
the place to be heated, and the outlet pipe may be fixed in or near the roof.
The number of gas jets in the smaller or outlet chamber will be propor-
tioned to the number used in the larger or inlet chamber so as to insure
the regular passage of the heated current of air. The heating chambers
may be arranged in other convenient positions, as in the manner shown in
the accompanying Drawings. When requisite, in the case of a very long

page_text: range of heating pipes or tubes, one or more intermediate heating chambers
may be used; they should be so placed and contain such a number of jets
that the current of air which may have given off its heat during trans-
mission receives additional heat from the intermediate heating chamber and
is always urged in one direction.
On the accompanying Sheet of Drawings Fig. 1 is a section of one
arrangement of my improved apparatus for heating conservatories or other
buildings by means of gas; Fig. 2 an outside view, and Fig. 3 a section
of a smaller apparatus for heating halls or apartments.
In Fig. 1a représents the inlet or heating chamber; b, the outlet or
current chamber; c, the gas pipe; d, a number of jets or burners in the
inlet chamber; e, a smaller number of jets or burners in the outlet cham-
ber; f, a pipe for admitting air into the inlet chamber; g, the door of the
inlet chamber; and h, the door of the outlet chamber for enabling the gas
to be lit or ignited; i; pipes for conveying the hot air from the inlet
chamber to the outlet chamber; k, the pipe attached to the outlet chamber
for conveying smoke or vapour out of the building; and I, part of the wall
of the building.
In Figs. 2.& 3, m represents the inlet or heating chamber containing
four jets of gas; n, the outlet or current chamber containing one or more
jets of gas; o, the inlet pipe for the admission of air; p, doors for
enabling the gas to be lit; and g, a basin or hollow for holding water when
required.
Having now described my Invention, and the manner of performing
it, I would have it understood that I do not confine myself to the precise
arrangements of the parts described, nor do I claim the use of the parts
separately, but what I do claim is, the employment of two or more chambers
heated and acting in mutual relation in the manner and for the purposes
substantially as herein described.
--In witness whereof, I, the said Theophilus Alfred Gilbert Willington,
have hereunto set my hand & seal, this Thirty-first day of
July, in the year of our Lord One thousand eight hundred and
sixty-six.
