Year: 1873

page_text: LETTERS PATENT to George Christopher Trout Bartley, of Ealing,
in the County of Middlesex, for the Invention of "IMPROVEMENTS
IN FIRE-PLACES.”
"
PROVISIONAL SPECIFICATION left by the said George Christopher
Trout Bartley at the Office of the Commissioners of Patents, with
his Petition, on the 19th March 1873.
I, GEORGE CHRISTOPHER TROUT BARTLEY, of Ealing, in the County
of Middlesex, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN FIRE-PLACES," to be as follows :—
The object of the Invention is to economize the heat evolved in the
combustion of fuel in fire-places.
For this purpose in addition to a passage by which, as in the ordinary
arrangements of register fire-places, the smoke and products of com-

page_text: bustion may pass direct to the chimney, that passage is formed to be
closed and a separate passage in front thereof is provided, by which
the smoke and products of combustion will then be immediately con-
ducted to a channel formed for the purpose down the inside of one
front side plate of the fire-place, and thence by a channel or channels
formed in or upon the hearth to the inside of the opposite front side
nlat and thence to the chimney.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said George Christopher Trout Bartley in the Great
Seal Patent Office on the 17th September 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
CHRISTOPHER TROUT BARTLEY, of Ealing, in the County of Middlesex,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Nineteenth day of March, in the year of our
Lord One thousand eight hundred and seventy-three, in the thirty-sixth
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said George Christopher Trout Bartley, Her
special license, that I, the said George Christopher Trout Bartley, my
executors, administrators, and assigns, or such others as I, the said
George Christopher Trout Bartley, 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 FIRE-PLACES," upon
the condition (amongst others) that I, the said George Christopher

page_text: Trout Bartley, 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 George Christopher Trout Bartley,
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 thereof, that is to say :-
The object of the Invention is to economize the heat evolved in the
combustion of fuel in fire-places. For this purpose in addition to a
passage by which, as in the ordinary arrangements of register fire-places,
the smoke and products of combustion may pass direct to the chimney,
that passage is formed to be closed and a separate passage in front
thereof is provided by which the smoke and products of combustion
will then be immediately conducted to a channel formed for the
purpose down the inside of one front side plate of the fire-place, and
thence by a channel or channels formed in or upon the hearth to the
inside of the opposite front side plate and thence to the chimney. The
channel from one side plate to the other may be formed in a raised
enclosure to the front and sides of the hearth. By these means the
side plates of the fire-place and the channels in or upon the hearth
become heated and communicate the heat thereof to the air of the

page_text: A is the fuel chamber as in ordinary fire-places, and B is the moveable
back plate or register which is formed to turn on pivots at 6¹, so that at
one time it may be inclined, as in Figure 4, to admit of the smoke and
products of combustion passing direct up to the chimney, or according
to my Invention it may be drawn forward and rest on the part 62, when
the heat and products of combustion rising from the fire will be con-
ducted by the channel c down inside one cheek or front side plate of the
stove to impart heat to that cheek, and thence by the channel d to the
channel e immediately within the opposite cheek or front side plate of
the stove, and thence up to the chimney to pass away to that chimney
in the ordinary way. By these means a large amount of heat which
under ordinary circumstances simply passes direct up the chimney is
controlled to heat the cheeks or side parts of the stove, and by them to
impart heat to the air in the room or apartment in which such fire-place
is fixed.
In first lighting the fire in the fire-place A it may be desirable to
leave the moveable back plate or register B for a time open direct to
the ordinary flue as in Figure 4, and then when a good draught has
been obtained to the fire it will be closed as in Figure 3, when the
heated products by passing through the channels c, d, and e will operate
to heat the side plates and thence the apartment. The passages c, d,
and e, may be formed of metal as part of the stove, or they may be
formed in the back brick or other work forming the setting of the stove
or in terra cotta, earthenware, or any other suitable material. ƒ is a
damper worked by a handle g for reducing or enlarging if necessary
the opening to the channel c. h is the handle of a lever arrange-
ment for opening and shutting the register B. 7 represents the
passages for admitting fresh air from outside the room when such
k is an open-
arrangement is wished to be added to the fire-place.
work guard round the channel d through which the fresh air from
I may be admitted.
Having thus described my Invention and means which I adopt in
carrying the same into effect, I would have it understood that what
I claim is the improvements in fire-places whereby the heated pro-
ducts of combustion from the fire in the grate may be controlled
to pass in channels formed for them within the sides of the stove and in

page_text: or upon the hearth, to aid in imparting heat to the room in place
of their passing direct up the chimney in manner substantially as
described.
In witness whereof, I, the said George Christopher Trout Bartley,
have hereunto set my hand and seal, this Seventeenth day of
September in the year of our Lord One thousand eight hundred
and seventy-three.
GEORGE C. T. BARTLEY. (L.S.)
