Year: 1872

page_text: LETTERS PATENT to Zephaniah Deacon Berry, of Pimlico, in the
County of Middlesex, Civil Engineer, for the Invention of
"IMPROVEMENTS IN THE CONSTRUCTION OF STOVE GRATES FOR DOMESTIC
PURPOSES."
Sealed the 12th November 1872, and dated the 16th May 1872.
PROVISIONAL SPECIFICATION left by the said Zephaniah Deacon Berry
at the Office of the Commissioners of Patents, with his Petition,
on the 16th May 1872.
I, ZEPHANIAH DEACON BERRY, of Pimlico, in the County of Mid-
dlesex, Civil Engineer, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN THE CONSTRUCTION OF STOVE GRATES FOR
DOMESTIC PURPOSES," to be as follows:-
This Invention relates to the construction of stoves for warming
rooms which belong to the class known as register stoves."
"
In accordance with this Invention the back plate of the stove above
the fire-grate, and which is ordinarily vertical or inclined backwards

page_text: from the front of the grate is so constructed and arranged as to be
inclined forwards at such an angle that the rays of heat from the
incandescent fuel and the products of combustion may impinge directly
upon and be deflected by the plate into the space in front of the fire-
place, instead of being carried away by the up draught of the chimney.
For these purposes the superficies of the deflecting plate should be so
curved as to form part of a circle, and thus present a focus for the
reception of the heat rays before mentioned, or, if not curved, the
deflecting plate should be placed at such an angle as to deflect the heat
rays as desired.
In order further to utilize the method of construction before described
the deflecting plate when it is desired to obtain the greatest possible
advantages from a stove grate constructed in accordance with this In-
vention is formed either as a hollow chamber or of a series of pipes
united together or placed in juxtaposition with each other, and which
chamber or pipes can be connected with any of the well-known arrange-
ments for heating by means of hot water, and thus the benefit of the
heat derived from the fuel consumed in the stove grate can be`cam-
municated to any room or space in proximity thereto.
In the stoves constructed in accordance with this Invention the
ordinary register back is altogether dispensed with, and to prevent the
smoke and other products of combustion being projected forwards into
the room a hanging deflecting plate is when necessary provided which
is capable of sliding up and down in suitable grooves in the front and
upper part of the framing of the stove, whereby the passage of the
rarefied products of combustion in any direction is prevented, except
towards the chimney. The two deflecting plates before mentioned act
together, and by throttling the uptake to the chimney increase the
draught, and effectually prevent the descent of the products of com-
bustion, In some cases it is desirable that the plates should be so
arranged by means of joints or hinges or other suitable and well-known
contrivances as to be moveable in order to allow of the chimney being
swept.
The bottom of the grate is constructed in a solid form of any
suitable material, and when desired the bars in front are hollow for the
purpose of containing water, and are attached to a water circulating

page_text: The deflecting plates and the solid bottom of the fire-grate may be
applied to any existing arrangement.
In new stoves the solid bottom is sometimes made so as to form in
one piece the bottom and the back of the stove by placing the same at
a sufficient angle. The solid bottom and back deflecting plate are thus
fixed towards each other in such a manner that they enclose a greater
angle than 90°, and the fire occupies the angular space between the
same, in front of which are the bars. When it is desired to heat currents
of air either for raising the temperature of the room or place in which
the fire is situated, or of any other place in proximity thereto; the back
of the fire-grate is provided with metal projections which become heated
by conduction, and which protrude into a space or chamber behind
the fire-grate, which space or chamber communicates with any con-
venient source of pure air. The air which enters the space or chamber
comes in contact with the metal projections, and is thus warmed, and
can be conducted in any direction and employed for any desired
purpose.
In order to produce a more speedy combustion of the fuel in fire-
grates constructed in accordance with this Invention an extra bottom
formed of bars is used when desired, and fitted alone or in conjunction
with the solid bottom above described. In such case a regulating front
provided with a valve is adapted to the space beneath the bars so as to
regulate the current of air supplied to the burning fuel.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Zephaniah Deacon Berry in the Great Seal Patent
Office on the 15th November 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ZEPHANIAH
DEACON BERRY, of Pimlico, in the County of Middlesex, Civil Engineer,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Sixteenth day of May, in the year of
our Lord One thousand eight hundred and seventy-two, in the thirty-fifth
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said Zephaniah Deacon Berry, Her special licence

page_text: that I, the said Zephaniah Deacon Berry, my executors, administrators,
and assigns, or such others as I, the said Zephaniah Deacon Berry, 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 THE CONSTRUCTION OF STOVE GRATES FOR DOMESTIC PURPOSES," upon the
condition (amongst others) that I, the said Zephaniah Deacon Berry,
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 Zephaniah Deacon Berry, 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, that is to say :-
My said Invention relates to the construction of stoves for warming
rooms which belong to the class known as register stoves."
In accordance with this Invention the back plate of the stove above
the fire-grate, and which is ordinarily vertical or inclined backwards
from the front of the grate is so constructed and arranged as to be
inclined forwards at such an angle that the rays of heat from the
incandescent fuel and the products of combustion may impinge directly
upon and be deflected by the plate into the space in front of the fire-
place, instead of being carried away by the up draught of the chimney.
For these purposes the superficies of the deflecting plate should be so
curved as to form part of a circle, and thus present a focus for the
reception of the heat rays before mentioned, or if the deflecting plate
is not curved it should be placed at such an angle as to deflect the heat
rays as desired.
In order further to utilize the method of construction before described
the deflecting plate when it is desired to obtain the greatest possible
advantages from a stove grate constructed in accordance with this
Invention is formed either as a hollow chamber or of a series of pipes

page_text: united together or placed in juxtaposition with each other, and which
chamber or pipes can be connected with any of the well-known arrange-
ments for heating by means of hot water, and thus the benefit of the
heat derived from the fuel consumed in the stove grate can be com-
municated to any room or space in proximity thereto..
In the stoves constructed in accordance with my said Invention the
ordinary register back is altogether dispensed with, and to prevent the
smoke and other products of combustion being projected forwards into
the room, a hanging deflecting plate is when necessary provided which
is capable of sliding up and down in suitablo grooves in the front and
upper part of the framing of the stove, whereby the passage of the
rarefied products of combustion in any direction is prevented, except
towards the chimney. The two deflecting plates before mentioned act
together, and, by throttling the uptake to the chimney, increase the
draught, and effectually prevent the descent of the products of com-
bustion. In some cases it is desirable that the deflecting plates should
be so arranged by means of joints or hinges, or other suitable and well-
known contrivances, as to be moveable in order to allow of the chimney
being swept.
The bottom of the grate is constructed in a solid form of any suitable
material, and when desired the bars in front are hollow for the purpose
of containing water, and are attached to a water circulating arrangement
for any desired heating purpose.
The deflecting plates and the solid bottom of the fire-grate may be
applied to any existing arrangement of stove grates.
In new stoves the solid bottom may be made so as to form in one
piece the bottom and the back of the stove by placing the same at a
sufficient angle. The solid bottom and back deflecting plate are thus
fixed towards each other in such a manner that they enclose a greater
angle than 90°, and the fire occupies the angular space between the
same, in front of which are the bars. When it is desired to heat currents
of air either for raising the temperature of the room or place in which
the fire is situated, or of any other place in proximity thereto, the back
of the firc-grate is provided with metal projections which become heated
by conduction, and which protrude into a space or chamber behind the
fire-grate, which space or chamber communicates with any convenient
source of pure air. The air which enters this space or chamber comes

in contact with the metal projections and is thus warmed, and can be
conducted in any direction, and employed for any desired purpose.
In order to produce a more speedy combustion of the fuel in fire-
grates constructed in accordance with this Invention, an extra bottom
formed of bars may if desired be used and fitted alone or in conjunction
with the solid bottom above described. In such case a regulating valve
is adapted to the space beneath the bars so as to regulate the current of
air supplied to the burning fuel.
Having thus declared and ascertained the nature of my said Inven-
tion, and in what manner the same is to be performed, I would observe
in conclusion that what I consider novel and original, and therefore
claim as constituting the Invention secured to me by the said herein-
before in part recited Letters Patent is, the construction of stove grates
in the manner and for the purposes herein-before set forth and described
or any mere modifications thereof.
In witness whereof, I, the said Zephaniah Deacon Berry, have here-
unto set my hand and seal, this Fourteenth day of November,
in the year of our Lord One thousand eight hundred and seventy-
two.
